Full textA compreensÃo de realidades complexas do setor pesqueiro exige, necessariamente, um profundo conhecimento da dinÃmica local, da lÃgica que norteiam as decisÃes dos pescadores e das tipologias da pesca. Esse processo deve, obrigatoriamente, preceder qualquer intervenÃÃo ou proposiÃÃo em prol do desenvolvimento da atividade pesqueira. A partir de uma metodologia fundamentada em um instrumental de cunho sistÃmico, o presente trabalho se propÃe analisar e diagnosticar os diferentes sistemas de produÃÃo implementados pelos pescadores do aÃude Pereira de Miranda, no municÃpio de Pentecoste- CE. Este estudo permitiu conhecer a variabilidade interna existente na pesca praticada atualmente pelos pescadores filiados a ColÃnia Z-16 e identificar trÃs sistemas de produÃÃo pesqueira que evoluÃram e diferenciaram-se ao longo do tempo em nove diferentes sistemas. Constatou-se a importÃncia de cada sistema, igualmente, pÃde-se colocar em evidÃncia uma importante diversidade de situaÃÃes vivenciadas pelos pescadores, dentre as quais destaca-se uma grande representatividade de pescadores em situaÃÃo de fragilidade social, demonstrando a pertinÃncia da elaboraÃÃo de aÃÃes diferenciadas de desenvolvimento pesqueiro. Os fatores que explicam a maior vulnerabilidade dos pescadores devem-se, sobretudo, a aspectos fundamentais concernentes ao desenvolvimento da cadeia produtiva da pesca artesanal desde a dÃcada de 60, onde a mudanÃas estruturais ao longo do tempo nÃo construÃram estratÃgias efetivas para a atividade. Nesse sentido, Ã absolutamente necessÃrio afirmar que a pluriatividade tem garantido a persistÃncia da atividade pesqueira no aÃude Pereira de Miranda, assim tambÃm como a diversificaÃÃo no Ãmbito da pesca, ainda que com limites, pode ser desenvolvida atravÃs de atividades econÃmicas que se caracterizam como estratÃgias individuais para acumular recursos que permitam a condiÃÃo de reproduÃÃo da pesca. Por fim, pode-se confirmar a importÃncia e a contribuiÃÃo de um instrumental de cunho sistÃmico para o estudo de realidades complexas que apresenta um conjunto de propostas que visam ajudar a superar o atual estÃgio de desenvolvimento do setor pesqueiro no aÃude estudado.

Full textThese last decades have been characterized by a great development of fishing techniques, contributing to the overexploitation of numerous marine fish stocks. In order to limit this collapse and to restore impacted communities, the implementation of management measures was necessary. Marine Protected Areas (MPAs), initially developed to protect remarkable habitats and associated biodiversity, are more and more used as a tool for spatial management of fishing activities, by adult export and/or larvae migrations from protected zones to surrounding fisheries.The aim of this PhD was to evaluate using indicators and predictive models (i) the impact of the Bonifacio Strait Natural Reserve (Corse) implementation on fish communities and (ii) the benefits of such management measures for the local artisanal fishery. We then developed a model and tested (iii) management scenarios for maintaining the spiny lobster resource, en decline in the reserve, into a sustainable exploitation way.Artisanal fishery catch data from south Corsica has permitted to highlight the indirect impact of recreational fishing on exploited fish communities structure and biomass. Whereas a decrease of the fishing effort may contribute to increasing catches per unit effort (CPUE), the analysis using response groups helped us to reveal differentiated increase of the artisanal fishery catches considering the interest of species to spearfishing. Moreover, we noticed than even if the BSNR legislation represents a benefit for many species, it is not sufficient for the emblematic red spiny lobster recover. Indicators issued from the ISIS-Fish model showed that higher restrictions on this resource access are necessary in the objective of sustainable fisheries

Full textThe traditional fishing communities in Cearà coast are promoters of social movements, characteristic of Artisanal Fisheries, which are made from certain social problems (fishing, housing, health, education, etc.). En-fronts in their group, they usually only is overcome by the struggles of these movements, the citizenship rights of their residents, producing a pedagogy inherent in this action. This reality gave rise to the development of such research, which aimed to study the educational process of the social movement in the community of Prainha do Canto Verde, Cearà coast in, trying to understand their role in organizing this community, with the aim of contributing to the social actors and institutional engaged in this activity for the development of public policies that effectively allow the exercise of social rights of these populations. To this end, we follow the steps of qualitative research instruments based on the following design: a case study descriptive qualitative explanatory concepts with ethnographic and action research, as researched and studied a unique community that has a value in itself for a period of five years. We also use the phenomenological approach that aimed to capture and understand the essence of the phenomenon sought, without, however, want a universality of analysis. The primary data were obtained from a non-random sample, intentional, by quotas. The collection of these was conducted from interviews (thirty-one) structured, semistructured and informal, individual, which were applied mainly with local leaders. We also borrowed to aid participant observation and the use of elements of the critical-dialectical methodology, to help us in meeting the interconnections and contradictions that make up the existing social fabric. Tool of the "field journal", where we recorded our impressions about the relationship between the main actors and subjects of research. To organize these data, we seek help of computers, by using a software QSR NUD * IST, as a support tool to analyze the transcripts of our interviews. Data analysis showed that the existing character education in the social movement of Prainha has as a cornerstone the process of mobilization and community organization, based on the grounds of liberating pedagogy of Paulo Freire, incorporated through the practice used by deep-ers of the movement which took into account the political nature of education through an authentic dialogic relationship. This process is responsible for the high degree of conscious-tion, politics and citizenship to that reached the main subject of this research. The result of this work is the strength of the social movement of Prainha in their activity and consequently, community organization, a trait evident in their identity and relevant factors in the social role of this movement, which appears as a model for other traditional fishing communities coast. Similarly, the collective actions of the group of fishermen in this community began to pass around our coast, linking, a move to strengthen local-level state that expands in union with the MONAPE. This research also gave us the opportunity to identify and present to the academic world, two contributions to the formaÃÃo/ constituiÃÃo theory on social movements in the field.
As comunidades tradicionais pesqueiras do litoral cearense sÃo promotoras de movimentos sociais, caracterÃsticos da pesca artesanal, que sÃo constituÃdos com base em determinados problemas sociais (pesca predatÃria, habitaÃÃo, saÃde, educaÃÃo etc.) enfrentados em seu coletivo, que normalmente sà sÃo superados nas lutas desses movimentos, produzindo uma pedagogia inerente a essa aÃÃo. Essa realidade ensejou a elaboraÃÃo desta pesquisa, que se propÃs estudar o papel do movimento social da Prainha do Canto Verde no processo educativo de comunidades tradicionais de pescadores artesanais litorÃneos, com o propÃsito de contribuir com os sujeitos sociais e institucionais que atuam nessa atividade para a elaboraÃÃo de polÃticas pÃblicas que efetivamente permitam o exercÃcio dos direitos sociais dessas populaÃÃes. Para tanto, procurou-se seguir os passos instrumentais da pesquisa qualitativa, fundamentada em um estudo de caso descritivo, qualitativoexplicativo, com concepÃÃes etnogrÃficas e da pesquisa-aÃÃo, pois se pesquisou e estudou uma comunidade singular que possui um valor em si mesma, durante um perÃodo de cinco anos. TambÃm se utilizou o enfoque fenomenolÃgico que teve como objetivo captar e compreender a essÃncia do fenÃmeno buscado, sem, contudo, pretender uma universalidade de anÃlise. Os dados primÃrios foram obtidos de uma amostra nÃo aleatÃria, do tipo intencional, por quotas. A coleta desses foi realizada mediante a aplicaÃÃo de entrevistas (31) estruturadas, semiestruturadas e informais, individuais, as quais foram aplicadas, principalmente, com as lideranÃas locais. TambÃm se recorreu à ajuda da observaÃÃo participante e ao emprego de elementos da metodologia crÃtico-dialÃtica, para ajudar no encontro das interconexÃes e contradiÃÃes que formam o tecido social local; da ferramenta âdiÃrio de campoâ, onde se registram nossas impressÃes acerca das relaÃÃes entre os principais sujeitos da pesquisa. Para organizaÃÃo desses dados, buscou-se o auxÃlio da informÃtica, mediante a utilizaÃÃo do software QSR NUD*IST, como ferramenta de apoio para anÃlise das transcriÃÃes das entrevistas. A anÃlise dos dados evidenciou que o carÃter educativo existente no movimento social da Prainha possui como pedra fundamental a mobilizaÃÃo e a organizaÃÃo comunitÃria, tendo como base a pedagogia libertadora de Paulo Freire, incorporada na prÃtica utilizada pelos fundadores do movimento, que levou em conta a natureza polÃtica da educaÃÃo por meio de uma autÃntica relaÃÃo dialÃgica. Esse processo à responsÃvel pelo elevado grau de conscientizaÃÃo, formaÃÃo polÃtica e cidadania a que chegaram os principais sujeitos desta pesquisa. O resultado do trabalho à a solidez do movimento social da Prainha, de sua mobilizaÃÃo e, por consequÃncia, da organizaÃÃo da comunidade, traÃo evidente de sua identidade e fatores relevantes no papel social desse movimento, que se mostra como referÃncia para as demais comunidades tradicionais pesqueiras litorÃneas. Da mesma forma, as aÃÃes coletivas do grupo de pescadores dessa comunidade passaram a repercutir em todo o litoral do Estado, estabelecendo uma articulaÃÃo, fortalecendo um movimento na contextura municipal-estadual que se amplia na uniÃo com o MONAPE. Esta pesquisa tambÃm concedeu a oportunidade de se identificar e apresentar ao universo acadÃmico duas contribuiÃÃes para a discussÃo da teoria sobre os movimentos sociais em comunidades tradicionais.

Full textIn this thesis, a survey carried out in 1988 is analysed in order to quantify the fishing production in the area of the medium river Tocantins, and to evaluate the importance of the fishing activity for the local populations. It is aimed to understand the adaptation of the techniques used by the fishermen to the ecological characteristics of the fisheries target species, considering the environmental changes during a hidrological cycle. The fishes adapted its life strategies to the seasonal variations, as well as, the community of fishermen adapted themselves to this space-temporal variability choosing apropriate capture strategies. The fishermen select the species based in their knowledgement of the environment, and of its organisms through the selectivity of the fishing gears. Fishermen are forced to supply all its production to the first merchant in exchange of financing the expenses in order to maintain the ships, buying fuel, uphold the equipments, and supply ice for fish conservation. A preference exists in capturing scale fish, as the curimatá Prochilodus nigricans and the jaraqui Semaprochilodus brama, in spite of having inferior commercial value. This preference is determined by their abundance and acceptance in the local market. Recent surveys performed by the Ministry of the Environment in the same area, supplied important information, which allow to conclude that alterations in the physical and biological characteristics of the medium river Tocantins, provoked by the construction of the dam of Tucuruí, allowed the mampará Hipophtalmus marginatus the conquest of the environments above this area. During the closed season, Siluriformes becomes the target of the fisheries, which afect will negatively the structure of the fish community. The curimatá population, extending from Imperatriz (MA) till the confluence zone of the rivers Araguaia and Tocantins has been estimated for 1988, using the depletion method, as 200 t, with an interval varying from 174 t to 227 t

Diante de um contexto de crise socioambiental da pesca artesanal, as mulheres, em famílias de pescadores, desenvolvem papéis de fundamental importância para a manutenção dos modos de vida das famílias. Apesar disso, elas enfrentam um processo de invisibilidade na pesca, social e institucional, que reflete as desigualdades de gênero. Assim, o objetivo principal desta pesquisa foi compreender quais os papéis das mulheres na manutenção dos modos de vida de famílias pesqueiras artesanais do estuário da Lagoa dos Patos, e compreender como esses papéis relacionam-se com a capacidade adaptativa dessas famílias, diante desse contexto de crise. Tem ainda como objetivos específicos: realizar um diagnóstico de gênero sobre a situação atual das mulheres no estuário da Lagoa dos Patos; analisar quais os papéis e estratégias desenvolvidas por elas, que contribuem para a manutenção dos modos de vida das famílias, e relacionar esses papéis com a capacidade adaptativa das famílias frente à crise. A pesquisa é quanti-qualitativa e envolveu pesquisas exploratórias, análise de gênero de dados secundários e também de entrevistas dos modos de vida de famílias de pescadores artesanais, em quatro localidades de pesca no município de Rio Grande - RS. Os dados quantitativos foram submetidos à análise simples de estatística descritiva e os dados qualitativos analisados pela metodologia da Análise Textual Discursiva (ATD). Ambos os resultados foram analisados com base em indicadores de equidade de gênero e também relacionados à capacidade adaptativa. Os dados desagregados por sexo mostraram, em geral, uma participação feminina baixa nas atividades da pesca, mas variável ao longo do estuário, além de maior vulnerabilidade das mulheres com relação aos direitos de propriedade na pesca. As entrevistas possibilitaram encontrar uma diversidade de atividades e papéis desempenhados pelas mulheres, concentrados nas atividades de pré e pós-captura, sempre interligados aos papéis reprodutivos. Esses papéis apresentaram indicadores ligados a componentes de capacidade adaptativa, associados à adaptabilidade, diversidade e flexibilidade; no entanto, apresentam, em geral, características de mecanismos de curto prazo. O contexto institucional, apesar de alguns avanços, ainda tem contribuído para diminuir a capacidade adaptativa das famílias, restringindo possibilidades de diversificação e flexibilidade, necessários para se adaptar ao contexto de incerteza e sazonalidade da pesca. Além disso, tem-se mostrado incongruente às relações de gênero existentes na atividade pesqueira, mantendo as desigualdades no acesso e no uso dos recursos, dos direitos de propriedade e da participação em espaços de representação e decisão.
Facing a context of socio-ecological crisis of artisanal fisheries, women in fishing families develop roles of fundamental importance for the maintenance of the livelihoods of the families. However, they face a process of invisibility in fisheries, social and institutional, that reflects the gender inequalities. Thus, the main objective of this research was to understand which are the roles of the women, in the maintenance of artisanal fishing families livelihoods of the Patos Lagoon estuary, and understand how these roles are related to the adaptive capacity of these families on this context of crisis. It also has specific objectives: carry out a gender diagnosis about the current situation of women in the Patos Lagoon estuary; analyze which are the roles and strategies developed for them, that contribute to the maintenance of the livelihoods of families and relate these roles, with the adaptive capacity of the families facing the crisis. The research is quantiqualitative and involved exploratory research, gender analysis of secondary data and also interviews of artisanal fishing families’ livelihoods in four fishing localities of municipality of Rio Grande - RS. Quantitative data were subjected to simple descriptive statistical analysis and qualitative data was analyzed by the methodology of discursive textual analysis. Both results were analyzed using gender equity indicators and also related to adaptive capacity. The data disaggregated by sex showed in general, a low but variable female participation on fishing activities, along the estuary; besides greater vulnerability of women with regard to property rights in fisheries. The interviews made it possible to find a diversity of activities and roles played by women, concentrated in pre and postcapture activities, always linked to reproductive roles. These roles had indicators linked to components of adaptive capacity, associated with adaptability, diversity and flexibility; however, have in general features of short-term mechanisms. The institutional context, in spite of some advances, still have contributed to reduce the adaptive capacity of families, restricting opportunities for diversification and flexibility needed to adapt to the context of uncertainty and seasonality of fishing. And in addition, has shown inconsistent to gender relations existing in fishing activity, keeping the inequalities in access to and use of the resources, property rights and participation in decision-making and representation spaces.

This study aims to present an overview of lobster fishing in the state of Paraiba from the perspective of social changes within the last 30 years, in the fishing communities of Baía da Traição and Acaú, both of them respectively in the north and south coast of the state. Although we consider these two communities as similar because they have set in artisanal fisheries one of their main local characteristics, we can also say that the two have very particular characteristics, over which we have closely analyzed throughout this work that examines current aspects reproduced from (dis)continuities and social changes arising from the implementation of new technologies, market demands, representation and social division of labor in artisanal fisheries, and more specifically in the lobster fishing. In this regard, we use the oral history as a research method, for it enables new versions of the history as it gives voice to multiple and different narrators, providing, especially history to be a more democratic activity, in charge of the communities themselves. Underneath the notion of maritime socio-anthropology, or socio-anthropology of fishing, we have studied the variety and complexity of the technical, social and symbolic systems developed by the coastal populations in the process of marine appropriation spaces, from where they derive their subsistence and surplus market. We also present significant changes in the notions of risk and inheritance, amending and/or replacing the production system from the fishing technique, the economic relations dependent on the markets and symbolic issues in the division of labor in traditional fishing.
O presente trabalho tem por objetivo apresentar um panorama da pesca da lagosta no estado da Paraíba sob a perspectiva das mudanças sociais ocorridas nos últimos 30 anos nas comunidades pesqueiras de Baia da Traição e Acaú, litoral norte e sul do estado, respectivamente. Apesar de considerarmos estas duas comunidades como similares, pelo fato de terem na pesca artesanal uma de suas principais características locais, podemos dizer também, que as duas possuem características bastante particulares, as quais nos debruçamos ao longo deste trabalho para analisar aspectos vigentes reproduzidos a partir de (des)continuidades e mudança social advindas da implementação de novas tecnologias, demandas de mercado, representação e divisão social do trabalho na pesca artesanal, e mais propriamente na pesca da lagosta. Neste sentido, tomamos a história oral como método de pesquisa, pois possibilita novas versões da história ao dar voz a múltiplos e diferentes narradores, propiciando, sobretudo fazer da história uma atividade mais democrática, a cargo das próprias comunidades. Sob a noção da sócio-antropologia marítima, ou ainda sócio-antropologia da pesca, estudamos a variedade e a complexidade dos sistemas técnicos, sociais e simbólicos elaborados pelas populações litorâneas no processo de apropriação dos espaços marinho, de onde retiram sua subsistência e o excedente do mercado. Apresentamos ainda mudanças significativas nas noções de risco e de herança e que altera e/ou substituir o sistema de produção a partir da técnica de pesca, das relações econômicas na dependência dos mercados e das questões simbólicas na divisão do trabalho na pesca tradicional.

Full textFisheries resources are being over-exploited worldwide. Excessive fishing can lead to trophic cascades and this exploration may be unsustainable. Therefore, management policies are urgent, but data are lacking to support such policies. In this sense, studies addressing interviews with fishermen have collaborated with the knowledge about the dynamics of fishing. The Brazilian artisanal fishing is the main economic and subsistence activity and the main source of protein for riverine Amazonian Caboclo populations and caiçara populations, who live in the coastal area of the Atlantic Forest. This study examined spatial and temporal ecological patterns in Brazilian artisanal fisheries in two ecosystems: the southeast coast of the Atlantic Forest and the fluvial Amazon; the data was based in interviews with fishermen on the course of several research projects. In Chapter 1 it was analyzed the fishery productivity in the southeastern coast. It was checked the variation in the average biomass of fish captured according to the interviews with fishers, due to temporal factors (fishermen’s age and date of their last fishery) and spatial factors (the region where the community of fishermen interviewed is located). There were analyzed interviews with 423 fishers, indicating that: a) there was a decrease in the biomass of fish caught over time, b) the biomass of fish caught was not influenced by the spatial factor c) there was no influence of age of the fisherman on the biomass of fish caught that was mentioned by them. Chapter 2 addressed the southeast coast of the Atlantic Forest and the Inland freshwater Amazon. It was analyzed the composition of fish caught, through their popular names mentioned by fishers and their mean trophic level. There were analyzed interviews with 658 fishers in the Amazon Basin (from 1987 to 2006) and with 821 fishers in to the southeast coast of the Atlantic Forest (from 1986 to 2009) (n = 1479 fishers). There was no variation in trophic level according to the time since the last fishing trip, and according to the spatial factors (ecosystem and region), and the region was the factor that most influenced the variation in trophic level. On the southeast coast of the Atlantic Forest species with similar trophic levels have been probably replaced by species of similar economic value over time. However, in the freshwater Amazon this pattern of species replacement was not observed. It is concluded that the decrease in biomass captured over time and the replacement of species on the Atlantic coast, may indicate that the fishery has been not sustainable. Preventive fisheries management measures should thus be devised.

A Praia de Redonda tem o segundo maior contingente populacional do municÃpio a que pertence â IcapuÃ, com 3.000 habitantes, com um total de aproximadamente 610 famÃlias, e tem o segundo maior nÃmero de embarcaÃÃes à vela destinadas à pesca de lagosta, atrÃs somente da capital Fortaleza. O estudo propÃe a construÃÃo de um modelo de gestÃo participativa â co- gestÃo â que pode promover a conservaÃÃo da pesca e dos recursos pesqueiros em grande escala, a partir da implementaÃÃo de modelo piloto em comunidades pesqueiras, integrando o elemento humano (usuÃrio) ao manejo pesqueiro. O objetivo geral dessa proposta foi realizar um levantamento do estado da arte do setor pesqueiro na comunidade de Redonda e estabelecer um marco de trabalho para o desenho dos planos de gestÃo dos recursos pesqueiros. Os planos de gestÃo incorporam princÃpios de sustentabilidade utilizando uma aproximaÃÃo de gestÃo integrada das Ãreas costeiras. O modelo de gestÃo foi baseado na participaÃÃo de todos os agentes envolvidos no setor pesqueiro, local ou nÃo, participando no processo de desenho, elaboraÃÃo e implementaÃÃo do plano de co-gestÃo. O estudo comeÃou a partir da aceitaÃÃo da necessidade de um novo modelo de gerenciamento pesqueiro cooperativo na Comunidade objeto do estudo, passando pela compreensÃo de que o sucesso da co-gestÃo pesqueira nÃo à somente dependente da boa implementaÃÃo do programa, mas tambÃm sobre o modo de como a idÃia foi concebida. Nosso foco no estÃgio da prÃ- implementaÃÃo nos levou a examinar a origem da idÃia e de que maneira, ou circunstÃncias, esse processo comeÃou na Comunidade para, a partir desse ponto, ter inÃcio a fase de levantamento de dados. A coleta de dados foi realizada entre 2007 e 2010 e esteve baseada na coleta de dados primÃrios e dados secundÃrios. O principal conflito relatado por moradores na Praia de Redonda à a luta de seus pescadores contra a presenÃa de mergulhadores na Ãrea de pesca de Redonda. A soluÃÃo da crise apresentada pela populaÃÃo à a criaÃÃo de uma AMP - Ãrea Marinha Protegida, com 2.200 kmÂ, dentro do que preconiza a lei do SNUC â Sistema Nacional de Unidades de ConservaÃÃo, beneficiando 13 comunidades pesqueiras pertencentes aos municÃpios de Aracati e Icapuà e aproximadamente 1930 pescadores. Foram contabilizadas 229 embarcaÃÃes pesqueiras somente em Redonda e, dessas, 180 unidades sÃo denominadas bote de casco e representam 78,6% da frota local. As principais artes de pesca utilizadas em Redonda sÃo as cangalhas para a captura de lagosta, enquanto que para a captura de peixe sÃo utilizadas as redes de espera, espinhel e linha de mÃo. A produÃÃo mÃdia de lagosta viva desembarcada em Redonda, no perÃodo de 2004 a 2009 foi 47,8 kg/barco/dia. AlÃm de lagosta, os peixes mais pescados sÃo: guaiÃba, cioba, dentÃo, sirigado, guarajuba, cavala, dourado, agulhÃo e albacora. O estudo demonstra a necessidade da implementaÃÃo do sistema de co-gestÃo pesqueira para a pesca artesanal na regiÃo leste do Estado como forma de propiciar a sustentabilidade da atividade pesqueira.
Redonda, a fishing village that is 200 km away from Fortaleza, capital of Cearà State - Brazil, located at geographical coordinates 04 25â 28,79â S and 037 54â 17,97â W. Redonda Beach has the second largest population in the city, to which it belongs - IcapuÃ, with 3,000 inhabitants, with a total of about 610 families and a large number of sailing lobster boats, second only to the State capital, Fortaleza. The purpose of this study is the building of a model of participative management â co-management â which can promote the conservation of fisheries and fishery resources in a large scale, through the implementation of a pilot model in artisanal fisheries villages, integrating the human element (user) to fisheries management. The overall objective of this proposal was to survey the state of the art of the fishing sector in the Redonda community and establish a frame of work for the design of management plans for fishery resources. Management plans incorporate principles of sustainability using an approximation of integrated management of coastal zones. The management model was based on the participation of all stakeholders in the local fishing industry or not, participating in the process of designing, developing and implementing the plan of co-management. The study began by accepting the need for a new model of cooperative fishery management in the Community object of study, and realizing that the success of fisheries co-management is not only dependent on the successful implementation of the program, but also how the idea was conceived. Our focus at the pre-implementation stage led us to examine the origin of the idea and in what manner, or circumstances, this process began in the Community, and from there, began the data collection phase. Data was collected between 2007 and 2010 and was based on primary and secondary data. The main conflict reported by residents in Redonda Beach is its fishermenâs struggle against the presence of divers in the fishing area of Redonda. The solution presented by the population was the creation of an AMP - Marine Protected Area, with 2,200 square kilometers, in accordance with SNUC - National System of Conservation Units, benefiting 13 fishing communities belonging to the municipalities of Aracati and Icapuà and about 1,930 fishermen. In Redonda, alone, 229 fishing boats were accounted for out of which 180 are called boat hull and represent 78.6% of the local fleet. The main fishing gear used are cangalhas to catch lobster and fish is caught through the use of gill nets, longlines and hand line. The average landing of live lobsters in Redonda, from 2004 through 2009 was 47.8 kg/boat/day. Other than lobster, some important landed species are: yellowtail snapper, red snapper, dentÃo, sirigado, guarajuba, mackerel, dourado, marlin and yellowfin tuna. The study demonstrates the need of implementation of a fisheries co- management system for artisanal fisheries in the eastern coast of the State as a means to provide the sustainability of the fishing activity.

Full textIn the context of the Brazilian artisanal fishery, the assurance of access to fishing territories and the development of value chains that consider both fish and fisherman are conditions that can be achieved through cooperative organization of production and communities. This work is based on the theoretical-methodological approaches of the collective actions and the shared management of common-use resources, especially marine resources. That background was used to analyze the historical trajectory of two cooperatives in traditional fishing communities in Brazil: the Cooperative of Artisanal Fishermen of Carutapera, in the indentation of the coastline in Maranhão State, and the Cooperative of Oyster Producers of Cananeia, in the South coastline of São Paulo State. The following methodological proceedings were carried: literature review, secondary data collection, direct observation of facts and phenomena, contact with stakeholders for the provision of data and analysis of the study cases context. The territories where each cooperative are located were described according to demographical, social, economical and environmental aspects, as a starter for the understanding of the current state of the study areas. The trajectory of the collective action that had led to the creation of the cooperatives were organized in a historical perspective, separated by phases, and it was listed/organized according by the main events that had contributed to the development of local cooperatives. The analysis of the data allowed the inference of what were the facts and key phenomena in promoting of the joint and coordinated action among individuals. The local value chain was described, and the social relations of production that deal with the market aspects in these cooperatives, were also identified as well as the traditional and ecological knowledge in what had occurred the production in the fishery systems. Finally, it was described the common areas used for fishing and artisanal mariculture, and how the property regimes employed works in the management of these territories. The realization of this research allowed the opposition between the data from both case studies in an identification prospect of similar and divergent patterns between the studied cooperatives. The main contributions were to the effect that it is necessary to pay attention to the context that drives the development of collective actions. When aimed to better living conditions for the communities, it needs to identify potential leaders, the reasons that make people cooperate with each other and the mechanisms that maintain trust between individuals, which in turn leads to feedback that solidarity cycle fabric on values such as reciprocity.

The traditional fishing with rafts is characterized by unpredictability, high stakes and inadequate work conditions. The extensive working hours, physical wear, inadequate nutrition, unsanitary conditions, lack of salvage equipment and instruments suitable working, added by the presence of changes in the nutritional status of fisherman, that contribute to the picture of insecurity in high seas, injuries and health. This study aimed to analyze the activity of the fisherman s from Ponta Negra, Natal / RN, and check the conditions of supply of these fishermen and their implications on health and development of their work. To this finality, was used a methodology based on the ergonomic work analysis employing techniques such as observational and interactional conversational action, listening to the answers, observation protocols, photographic and video records. The script conversational dynamic action was developed from literature searches about the artisanal fisheries, culture and food habits of this population, and analyzes the overall situation of focus and two reference situations. To collect data on the usual diet of fisherman as well as quantitative and qualitative analysis that was used for data analysis and 24h recall the Food Frequency Questionnaire (FFQ). The impact of this power to the health of fisherman was evaluated performing a nutritional assessment. The results revealed that the fishermen carry out their activities with poor working conditions, health and nutrition. Feeding practices of these fishermen undertake development work, making it even more stressful, as well contributing to the emergence of Chronic Noncommunicable Diseases. The management of the activity, as well as the current structure of the vessel, also contributes to the adoption of inappropriate feeding practices during the shipment of catch. The results of this indicate the need for adequate interventions in order to assist in recovery and / or maintenance of health of fisherman minimizing reflections of nutritional disorders for the development activity by improving the quality of life in this population

Full textBycatch mortality in longline fisheries is considered the main threat for numerous seabirds worldwide. In the Mediterranean, this mortality is seriously affecting the viability of some populations. However, the information available on the level and extent of its impact is scarce. Likewise, no mitigation strategy has yet been implemented in the fleet. The present thesis aims to asses and contribute to the knowledge about the seabird bycatch in longline fisheries of western Mediterranean, as well as to identify the most appropriate mitigation strategy for the fleet. The study has focused on demersal longliners, since they use the most dangerous gear for seabirds and also because there is little information available. This study shows a high seabird mortality on longlines, in particular of the three endemic shearwaters: Scopoli’s (Calonectris diomedea), Balearic (Puffinus mauretanicus) and Mediterranean (P. yelkouan), calling for urgent actions to reduce their bycatch rates. There are several factors influencing on bycatch risk, but the most important are the season and the setting time. Other influential factors are the bait type, wind conditions, longline configuration, proximity to the colonies and the number of hooks set. Moreover, in Scopoli’s shearwater, the reduction of discards by trawlers led to increased interaction between these seabirds and longliners, thus increasing the bycatch risk. Consequently, the incoming legislation that intends to ban discards will likely aggravate this problem. This study also shows adult- and sex-biased mortality in longline fisheries. In addition, this mortality is more pronounced but not limited to the local colonies. It appears that night setting would be the most effective method to reduce bycatch without compromising target or non-commercial species. However, this should be confirmed in longliners targeting species other than European hake. A temporal closure of the fishery is also a promising strategy, although its effects on fishing activity should be carefully evaluated. Others methods include increasing the longline sink rate and avoiding baits attractive to seabirds. The high diversity of strategies and gears hampers the identification of solutions applicable to the whole fleet. Consequently, it would be necessary to establish a set of different measures that can be adapted to the majority of fishing methods.

Full textThe fishery characterizes coastal human populations, as the caiçaras from south coast of São Paulo state. By making the fishery in an artisanal method, these fishermen explore the aquatic environment in a peculiar way. To maintain and recreate their subsistence system, the fishermen acquire a considerable and significant knowledge about the nature and its cycles. In their productive activities, they establish and maintain large diversity of direct interactions with their environment. However, over the last few decades these populations have incorporated new economic activities, as service rendering. The tourism associated to sportive fishery its, eventually, an alternative form of income to the fisherman. They provide several forms of services and apply their knowledge about fishery resources to the new activity. Such a new reality brings out new challenges to the caiçara population and its traditional way of life. The present work had three central objectives and so, three lines of investigation. (1) Analysis of the artisanal fishery activity related to the methods and fishery points used, the seasonality and captured fish species and the environmental conditions that influence the fishery activity, according to the artisanal fisherman knowledge. The relationships between the fishermen and other economic activities were also studied. (2) An ethnoictiological study concerning aspects of fish morphology and behavior, emphasizing its ethnoecology. The correspondences and divergences between the caiçara ethnoknowledge and the scientific literature were also identified. (3) The characterization of sportive fishery practiced in the studied caiçara communities, tracing the sportive fishermen profile. The relationship with the artisanal fishermen and possible influences in their way of life were also analyzed. The present research was carried out in the caiçara communities of Barra do Ribeira, and Jairê (Iguape city), Carijo, and Porto Cubatão (Cananéia city), and Pedrinhas (Ilha Comprida City). The data collection was carried out by using interviews, direct observations, and biological material collection. In all the five studied communities, some common characteristics related to the analyzed aspects were verified. The artisanal fishery still characterizes itself as one of the main income sources. Its dairy practice is still quite frequent, showing its strong presence in the quotidian of the caiçaras communities. Nevertheless, other economic activities related to the sportive fishery in three of the studied communities were observed. According to the fishermen, the fishery production is influenced by variables as moon phase, tide and rainfall. The ethnoknowledge guides the traditional fishery activity and has been applied to the other economic activities. For instance, the collection of natural fishing bait to sell to the sportive fisherman. There is still a large ecological knowledge about the fishes among the artisanal fisherman. It was also verified a high correspondence between the ethnoknowledge of the artisanal fisherman and the scientific knowledge. In three of the communities studied, tourism associated to sportive fishery has been intensified, competing for resources and spaces with the artisanal fishery, leading to alterations in the routine of the caiçaras, which have not yet been evaluated in ecological and sociocultural terms. The increase of the sportive fishery demands knowledge and planning to prevent negative sociocultural and environmental effects. Studies about its impact on the local population dynamics and fishery stocks are necessary.

Full textSmall-scale artisanal (or subsistence) fisheries have been little studied. Few studies have attempted to understand the factors that influence the fisheries on this scale. Human populations that depend upon natural resources show good knowledge about the environment and the exploited resources. Dams are among the main impacts affecting inland fisheries and there is little knowledge about the impacts of dams on fisheries over time. Information from local populations and subsistence fishing may improve and complement the scientific knowledge on fisheries and dam’s impacts. The aim of this study is to analyze the dynamics of subsistence fishing in the Lower Tocantins River (Brazilian Amazon) through interviews and fish landings. We tested the efficiency of recording fishermen’s local ecological knowledge through interviews for assessment of the fisheries dynamics and environmental changes caused by dams in large rivers (1st chapter). We also analyzed the fishing income and the variables that influence the biomass of fish caught in five fishing communities of the Lower Tocantins River (2nd chapter). We conducted 300 interviews with fishermen in nine riverine communities and recorded 606 fish landings in five of these communities in 67 sampling days. Through interviews it is possible to identify the most caught fish species, the fishing gear and gillnet mesh sizes used by most of the fishermen, and the seasonal fish abundance patterns. The composition of fish landings changed 22 years after the dam’s closure. Through interviews with fishermen, also it was possible to identify the species of fish that increased (Plagioscion squamosissimus), decreased (Characidae, several species of pacu) and even disappeared (Semaprochilodus brama) after the dam’s closure. The annual production and financial income of fishing have been reduced by about 55% after the dam’s closure. Most of the variation in the biomass of fish caught is explained by variables related to the fishing effort and to the fisherman’s behavior , such as fishing time (35%), number of fishermen (30%) and distance to fishing grounds (20%). Interviews with fishermen showed to be fast, reliable and inexpensive methods to obtain important information about the fisheries and the impacts downstream from a dam in a large Amazonian river. The local ecological knowledge of resource users can complement long-term ecological research efficiently. The fishermen, their knowledge and their behavior should be considered when developing fisheries management plans appropriate to local realities. This seems to be the most promising way to ensure the maintenance of biodiversity, conservation of fishing resources, and maintenance of artisanal fisheries as an economic activity.

Resumo: Transformações biofísicas nos solos, nos oceanos e na atmosfera provocados por atividades humanas e processos naturais, têm aumentado consideravelmente desde o início do século XX. Estas transformações e mudanças na estrutura e função de sistemas socioecológicos podem ser percebidas por populações humanas. As comunidades de pescadores artesanais de Ubatuba, estado de São Paulo, Brasil, que ainda vivem diretamente dos recursos pesqueiros percebem tais mudanças e têm se adaptado a elas ao longo do tempo, a fim de manter suas subsistências e renda. O conhecimento ecológico local (CEL) a respeito dos sistemas socioecológicos costeiros destas comunidades pode auxiliar na redução da vulnerabilidade e aumento da capacidade adaptativa, em faces de mudanças ambientais globais. Este estudo visa contribuir com informações sobre mudanças ambientais globais, incluindo as mudanças climáticas, bem como seus impactos sobre o ambiente local e as populações humanas, e verificar como populações de pescadores artesanais do litoral norte de São Paulo percebem e se adaptam a tais mudanças. A hipótese considerada neste estudo consiste em que o CEL de pescadores artesanais com relação ao ambiente natural é utilizado para reduzir a vulnerabilidade e aumentar a capacidade adaptativa de comunidades de pesca artesanal costeira frente às mudanças ambientais globais, dentre elas as mudanças climáticas. Os resultados apontam que as comunidades pesqueiras do litoral norte de São Paulo fazem uso do CEL para entender os efeitos das mudanças ambientais nos ecossistemas costeiros, assim como têm capacidade de se adaptarem a tais mudanças ao longo do tempo, diminuindo a vulnerabilidade de sistemas socioecológicos costeiros frente às mudanças ambientais globais. A análise em nível local da percepção de mudanças ambientais e sociais por populações humanas subsidia o entendimento dos efeitos dessas mudanças em ecossistemas complexos e este entendimento pode contribuir para futuros planos de manejo em áreas costeiras brasileiras
Abstract: Biophysical transformations on land, in the oceans and the atmosphere, provoked by human activities and natural processes have increased considerably since the beginning of twentieth century. These changes, with affect the structure and function of coupled socio-ecological systems, are being observed by human society. Coastal fisheries communities of Ubatuba, São Paulo state, Brazil, highly dependent upon fisheries observe such changes and have adapted to them over time in order to maintain communities, livelihood activities and income. The detailed local ecological knowledge (LEK) of these communities regarding coastal socio-ecological systems can help reducing the vulnerability and increasing adaptive capacity, in face of global environmental change. This study contributes with knowledge global environmental change, the impacts on the local environment and human beings and how the communities realize and adapt to these changes. The hypothesis drivinhg study is that LEK of coastal fishers about the natural environment contributes to reduce vulnerability and to increase adaptive capacity in the smll-scale coastal fisheries in the face of global environmental change, including climate change. The findings show that the small-scale coastal fishers of the North coast of São Paulo make use of LEK for understanding the effects of the environmental change on the coastal ecosystems, as well as how they can adapt to such changes over time, thereby reducing the vulnerability of coastal socio-ecological systems in face of global environmental changes. An analytical insight into the local level regarding the perception of environmental and social change are essential to provide a better understanding about the effects of diverse changes in the complex ecosystems. Such understanding can contribute to future design of resources management plans in Brazilian coastal areas.

Full textSea fishing is often characterized by the unsustainable exploitation of fishing resources in most parts of the world. The strong demand forseafood causes the fishing industry to grow, which is steadily constraining its own geographical limits and its technical capacities,generating conflicts caused by the massive exploitation of fishing areas that, until recently, were only occupied by artisanal fishermen.The Amazonian border region in northern Brazil illustrates this context, while artisanal fishermen in Oiapoque (north of the state ofAmapá) are subject to the invasion of fishermen from different regions. The thesis addresses the artisanal fishing dynamics in Oiapoque,based on the concept of territory, through the relations engaged in by the fishermen, the productive chain, the forms of conflict for thefishing area, the restrictions imposed by the general regulations in a protected area. This work is qualitative and quantitative methodology:direct observation, questionnaires, interviews and maps. This research highlights many shortcomings in the current system (publicpolicies, resource and ecosystem assessment, etc.) in order to understand, monitor and sustainably manage the resource. Theseshortcomings encourage the disorderly exploitation of fishing resources, which threatens the future of artisanal fishermen and marinebiodiversity. Local artisanal fishermen are now under a fairer and more stringent enforcement of the regulations in the protected areaaimed at preserving its use, while avoiding overfishing
A pesca marítima é frequentemente caracterizada pela exploração insustentável dos recursos pesqueiros na maior parte do mundo. A forte demanda por frutos do mar favorece o crescimento da indústria pesqueira, que está constantemente pressionando seus próprios limites geográficos e os de suas capacidades técnicas, o que está causando conflitos com a exploração maciça de áreas de pesca até então ocupada por pescadores artesanais. A região amazônica transfronteiriça do norte do Brasil ilustra esse contexto, onde os pescadores artesanais do município de Oiapoque sofrem com a invasão de sua área por pescadores de diferentes regiões. Esta pesquisa visa uma melhor compreensão da pesca na costa atlântica da Amazônia, suas questões econômicas, sociais e ambientais. A tese aborda a dinâmica da pesca artesanal em Oiapoque, norte do estado do Amapá. Baseia-se no conceito de território, através das relações exercidas pelos pescadores, a cadeia produtiva, as formas de conflito para a área de pesca, as restrições impostas pela regulamentação geral com a presença de uma área protegida. A metodologia é qualitativa e quantitativa, consiste em observação direta, questionários, entrevistas e elaboração de mapas. O processamento de dados geográficos, obtidos a partir de sistemas a bordo de embarcações de pesca e levantamentos de campo permitiu a identificação de áreas de pesca na área marinha e sua partilha com conflitos entre os diferentes usuários. Os atores do conflito vêm de diferentes níveis (local, nacional e internacional) e se manifestam em diferentes intensidades da área de pesca. A pesquisa destaca muitas deficiências no sistema atual (políticas públicas, conformidade regulatória, avaliação de recursos e ecossistemas, etc.) para entender, monitorar e gerenciar de forma sustentável o recurso pesqueiro. Estas deficiências encorajam a exploração desordenada dos recursos pesqueiros, o que ameaça o futuro dos pescadores artesanais e da biodiversidade marinha.

The populations ofelasmobranchsare especially susceptibleto overexploitationdue to the continuedexploitation offish stocks, to anthropogenicactivitiesoncoastal and marine environments, to theirk-strategists characteristicsand the lack ofcontrol of theirtotal landings, mainly from theartisanal fleet. In this scenario, it shows the necessity of develop new management techniques of fishing resources that take into account the local ecological knowledge (LEK) of all those involved in this activity.The present studyaimed tounderstand theLEK aboutthe fishing activitiesofelasmobranch inthe city of Raposa-MA,within a perspectiveof building aco-management. Thus,54artisanal fishermenwere interviewedthroughfreeinterviews andsemi-structured forms,with a mean ageof44.9 years, more than half (51.85%) withincompleteelementary schooland64.81% exclusivedependent on fishingfortheirmonthly income.

Through the CEL of artisanal fishers were described 45 generic folks, with the determination of 7 monotypic and 17 polytypic, of which 25 scientific species were identified through the description of fishermen and research in the scientific literature, and five of these are listed as endangered in level national or global. On the influenceof abioticfactors infishing activity, fishermen listedseveralnames to describethe lunar phasesbut did not determinethe most suitablefor fishing,and consideredunfavorablestrong windsand high temperatures,commonin the dry season, especially starting in August.That way, this study exposes theCELof local fishermenand gapsofknowledgeon the dynamicsand conservation ofelasmobranchsin the region.
As populações de elasmobrânquios são especialmente suscetíveis à sobre-exploração devido àexploração contínua dos estoques pesqueiros, às atividades antropogênicas em ambientes costeiros e marinhos, às suas características k-estrategistas e à falta de controle de seus desembarques totais, principalmente, da frota artesanal.Neste cenário, mostra-se necessárioo desenvolvimento de novas técnicas de manejo dos recursos pesqueiros que levem em consideração o conhecimento ecológico local (CEL) de todos os envolvidos nessa atividade. O presente estudoteve o objetivo de compreender o CEL sobre as atividades pesqueiras dos elasmobrânquios no Município de Raposa – MA, dentro de uma perspectiva de construção de uma gestão compartilhada. Assim, foram entrevistados 54 pescadores artesanais através de entrevistas livre e formulários semiestruturados, com média de idade de 44,9 anos, mais da metade (51,85%) com ensino fundamental I incompleto e 64,81% dependentes exclusivos da pesca para sua renda mensal. A captura de elasmobrânquios ocorre de forma acidental por três tipos de embarcações (o barco, a biana e a MAR) com a utilização de redes de emalhar direcionadas às espécies ósseas de maior valor comercial. O indicador de atitude conservacionista exibe a baixa intenção de conservação destes estoques pelos pescadores. Através do CEL dos pescadores artesanais foram descritos 45 genéricos folks,com a determinação de 7 monotípicos e 17 politípicos, dos quais 25 espécies científicas foram identificadas através da descrição dos pescadores e de pesquisas na literatura científica, destas cinco estão listadas como ameaçadas de extinção em nível nacional ou global. Sobre a influência dos fatores abióticos na atividade pesqueira, os pescadores listaram diversos nomes para descrever as fases lunares, mas não determinaram as mais adequadas para a pesca, e consideraram desfavoráveis os ventos fortes e temperaturas altas, comuns no período de estiagem, especialmente, a partir de agosto. Dessa forma, o presente estudo expõe o CEL dos pescadores locais e as lacunas desse conhecimento sobre a dinâmica e a conservação dos elasmobrânquios na região.

The river Apodi-Mossoró, there is artisanal fishing in the region near the city of Mossoro is already showing clear signs of environmental problems such as pollution from the dumping of sewage, reduction of its riparian vegetation and sedimentation. This environmental degradation worsens even more because of the degree of water contamination in the area of urban area of Mossoro. The main purpose of study is to assess the social and environmental aspects of the Z-55 colony on the Mossoro-RN river. To analyze the environmental condition of water and fish Apodi-Mossoró river, was made the quantification of total and fecal coliforms, Escherichia coli, mesophilic bacteria, Staphylococcus aureus and Salmonella sp., and the social conditions were assessed through an interview with colony of fishermen. This study was conducted in the municipality of Mossoró-RN, more precisely in Apodi-Mossoró river stretch that cuts through this city. For environmental analysis of water and fish collections were held in Apodi-Mossoró river stretch that bisects the urban area in six different geo-referenced points according to MacFaddin methodology. For social interviews with artisanal fishermen a questionnaire was administered at the headquarters of the Z-55 cologne, as well as in the homes of fishermen and Apodi-Mossoró river. The values found for the microbiological analysis of water and fish have proven unsatisfactory, showing how the river is impacted anthropically. According to the responses of interviews with artisanal fishermen, have resulted in the positive environmental perception thereof on pollution Apodi-Mossoró river. We conclude that the Apodi-Mossoró river need for further environmental monitoring as it is with your water and your fish with microbiological parameters outside the standards of the current legislation, as well as artisanal fishermen belonging to the Z-55 cologne is the perception the Apodi-Mossoró river is polluted, but unaware of the major diseases that can cause pollution
O rio Apodi-Mossoró, onde ocorre à pesca artesanal, no município de Mossoró já apresenta sinais claros de problemas ecológicos, como poluição decorrente do lançamento de esgotos, diminuição de sua mata ciliar e assoreamento. Esse quadro de degradação ambiental se agrava ainda mais em virtude do elevado grau de contaminação da água na área do perímetro urbano de Mossoró. O objetivo principal de trabalho é avaliar os aspectos socioambientais da colônia Z-55 quanto ao Rio Apodi-Mossoró, RN. Para analisarmos a condição ambiental da água e dos peixes do Rio Apodi-Mossoró, foi feita a quantificação de coliformes totais e termotolerantes, Escherichia coli, bactérias mesófilas, Staphylococcus aureus e Salmonella sp., e as condições sociais foram avaliadas através de entrevistas com os pescadores da colônia. O presente estudo foi realizado no município de Mossoró-RN, mais precisamente no trecho do Rio Apodi-Mossoró que corta a zona urbana. Para as análises ambientais as coletas de água e peixe foram realizadas em seis pontos distintos georreferênciados de acordo com a metodologia de MacFaddin. Para as entrevistas sociais junto aos pescadores artesanais foi aplicado um questionário na sede da colônia Z-55, bem como nas casas dos pescadores e as margens do Rio Apodi-Mossoró. Os valores encontrados para as análises microbiológicas da água e do peixe se mostraram insatisfatórias, mostrando o quanto o rio se encontra impactado. De acordo com as respostas das entrevistas realizadas com os pescadores artesanais, temos como resultado a percepção ambiental compatível ao nível de poluição do Rio Apodi-Mossoró. Concluímos que o Rio Apodi-Mossoró necessita de um monitoramento ambiental mais aprofundado, pois se encontra com sua água e seu peixe com parâmetros microbiológicos fora dos padrões da legislação vigente, bem como, os pescadores artesanais pertencentes à colônia Z-55 tem a percepção de que o Rio Apodi-Mossoró se encontra poluído, porém desconhecem das principais doenças que essa poluição pode causar

The jangadeiros in the work activity are exposed to diverse and constant variability, which are extremely important to know in order to understand this activity and the risks they are exposed. The current study aims to analyze the work activity raftsmen of Ponta Negra beach in Natal, focusing on handling and quality of the fish sold by them to propose through the social construction recommendations for improving its product. To achieve this purpose was used a methodology inspired by the ergonomic work analysis using techniques observational and interactional. He was also made an assessment of fish sold by jangadeiros Ponta Negra, this evaluation was a sensory evaluation using the method "Torry Research" adapted by Vieira (2004) in order to assess the level of quality fish. In general it was observed that the fish originated from the fishing that rafts in Ponta Negra, have a good degree of freshness. But it was found that some ways of handling and storage can be improved

Full textO fechamento da temporada de pesca da lagosta no Nordeste Brasileiro, que, atualmente, vai de 1 de janeiro a 30 de abril (portaria/IBAMA n 137/94, de 12 de dezembro de 1994), à conhecido como o âdefeso da lagostaâ. Nesse perÃodo, as comunidades de pescadores litorÃneas que vivem exclusivamente da pesca desse crustÃceo passam por suas maiores necessidades e enfrentam seus piores problemas socioeconÃmicos. Assim, os pescadores artesanais dessas comunidades ficam mais vulnerÃveis e dependentes das aÃÃes, intervenÃÃes e favores dos agentes que atuam na comercializaÃÃo da pesca local. Essa realidade ensejou a elaboraÃÃo da presente pesquisa, que procurou observar e identificar caracterÃsticas dos fenÃmenos sociais e econÃmicos da pesca artesanal de lagosta, na comunidade de Redonda, localizada no MunicÃpio de Icapuà (CE), descrevendo-os, classificandoos e correlacionando-os com aÃÃes e intervenÃÃes dos comerciantes da pesca local, principalmente com relaÃÃo ao perÃodo do defeso. Para a realizaÃÃo do trabalho, foi desenvolvido um estudo quantitativo e qualitativo, no qual, para a coleta dos dados primÃrios utilizados, recorreu-se aos instrumentos metodolÃgicos da observaÃÃo participante, de questionÃrios administrados e entrevistas estruturadas e informais. Estes foram utilizados numa populaÃÃo de aproximadamente 400 pescadores, em meio a qual foram aplicados 65 questionÃrios e entrevistados os 10 principais intermediÃrios residentes no local, assim como 11 lideranÃas formais e nÃo formais. Deve-se salientar que a definiÃÃo do problema da investigaÃÃo teve a participaÃÃo direta da comunidade envolvida. Os resultados do estudo apontam para uma participaÃÃo ativa dos intermediÃrios, nos segmentos econÃmicos e sociais da pesca artesanal na comunidade, principalmente naqueles referentes aos financiamentos de seus meios de produÃÃo e nas emergÃncias de saÃde de seus habitantes. Conseguiu-se, tambÃm, identificar e quantificar a renda mÃdia bruta mensal dos pescadores, de maneira geral e por categoria, e observou-se que, quanto mais desprovidos sÃo de seus meios de trabalho, menor sua remuneraÃÃo e maior sua expropriaÃÃo por aqueles agentes detentores do capital e controladores do processo de comercializaÃÃo. Em face dos resultados alcanÃados, concluiu- se que os intermediÃrios (barraqueiros) da comunidade de Redonda contribuem para a inÃrcia do pescador no perÃodo do defeso, assim como estÃo se apropriando de seus meios e fatores de produÃÃo. Serà atravÃs de processos educativos, via entidades associativas, conscientizando o pescador nos questionamentos de seus problemas, que a categoria vai poder buscar soluÃÃes para resolve-los e, minimizar as interferÃncias impostas pelos agentes da intermediaÃÃo. à tambÃm atravÃs destes processos, que deverà fluir toda e qualquer aÃÃo de intervenÃÃo de governo na comunidade.
This study was developed in the fisherman community of Redonda in Icapuà county in the eastern side of Cearà State-Brazil. The research aimed to observe and identify social and economic characteristics of the lobster small-scale fishing in the community, describing, classifying and correlating them to the action and intervention of local fishery trademan, specially in relation to the fisheries closed season. To this, a quantitative and qualitative study was developed through the aplication of participant observation, administrative questionnaries, informed and structured interviews. They were applied to a population of four hundred fishermen, a total of sixty five questionnaries and twenty one interviews. From those last, ten were the main market middlemen and eleven, formal and non formal leadership. It is important to state that the local community had a participative role in the definition of the research problem. The results of the study point to the lack of income and its consequences as the main problem of this community as well as the negative intervention of the middlemen who provide many to them for the production means and health emergencies. Facing those problems it was concluded that the market middlemen of the community of Redonda have contributed to the lethargy of the fishermen during the fisheries closed season, as well as they are appropriating of their means and production features. It will be through the fishermen association, organizative and educative processes that the conscientization of their problems will be done. Then, the search for solutions and the minimizations of the interference of the market middlemen will be possible. It will be also through these processes that any government intervention in the community has to be done.

Full textHuman ecology examines the relationships between human populations and natural resources and can generate useful information for management of fishing activities in coastal areas. This study was conducted in the years 2007 and 2008 in two fishing communities of southern Brazilian coast, located at Guarda do Embaú (GE) and Pinheira beaches (PP), state of Santa Catarina. The main objectives of this study were: analyze the strategies of fisheries and interactions between different groups in the activities of artisanal fisheries subsistence, identifying the decisions and strategies used by fishermen on the fishing trade and register the local ecological knowledge (LEK) of fishers of two communities over the fish, comparing it with scientific knowledge and comparing the LEK between communities. On the beach GE was the number of registered fishers and the following variables of fishing through interviews with fishers: origin, economic activity, fishing gear and techniques, time spent fishing and fishing spots used in addition to the composition and biomass fishes. At the time of migration of mullets (Mugil platanus and M. curema), local fishers and fishers occasional (other regions) have intensified the activity of fishing, logging a higher yield fishery. The fishing techniques (espia and sarraio used with cast nets and fishing pole) used by fishers (n = 163) differed in yield and selectivity. The espia was the most productive technique. The sarraio and espia techniques were more selective when compared to the fishing pole. There was evidence for niche sharing between local fishers and occasional about the use of the area of fisheries and capture strategies used. Indication, rules of use of space fishing: respect for the occasional fishers on the fishing spot only used by local fishermen, and a territorial behavior of the local fishers who defended the fishing spot through social sanctions (intimidation). Were recorded the socio-ecological factors that promote co-management plans for fisheries, as the presence of the fishermen's association and others. Fishing on the beach Pinheira was analyzed using the model of optimal foraging from a "central place" (point of exit of fishing vessels), which provides that the fishers seek to maximize gains (biomass of fish caught) in points more distant fishing intensifying the fishing effort. Were recorded the following data of fishing landings (n = 285): techniques and fishing areas, travel time to the fishing areas (costs), time in the fishing areas (effort) and species caught (benefits). The behavior of the fishers did not follow the model assumptions of optimal foraging. The fishers of the fishing techniques caceio and fundeio, visited the fishing areas with the highest probability of good catches, regardless of distance from the "central place". To find these places the fishers used probing techniques indicated that the fishing areas of higher productivity. Were also conducted interviews with fishers from the beaches of GE (n = 28) and PP (n = 31), with over ten years experience in the activity, in order to register the local ecological knowledge (LEK) and compare it with the scientific literature and other biological studies. Were registered fishers LEK on the abundance, breeding period and food items eaten by 7 species of fish and 13 species at GE in the PP. Were collected five species of fish of the fishers at PP for analysis of the reproductive aspects and feeding. Fishers from both communities have a detailed knowledge about the species of fish, which was influenced by such factors as the usefulness and abundance of fish and was in accordance with the scientific literature, most of the time. Some information obtained from LEK was not found in the literature and others not consistent with the literature used to formulate hypotheses for future investigations. Differences in the KEL were fishermen on the biology of the species of mullets and bluefish (Pomatomus saltatrix), compared to the two fishing communities. The recognition of the particularities of different fishing communities allows driving the strategies for managing resources in a participatory manner and more efficiently, through practices of comanagement fisheries.

Full textThe present study is one of the first attempts to analyze the societal importance of seagrasses (marine flowering plants) from a Natural Resource Management perspective, using a social-ecological systems (SES) approach. The interdisciplinary study takes place in East Africa (Western Indian Ocean, WIO) and includes in-depth studies in Chwaka Bay, Zanzibar, Tanzania. Natural and social sciences methods were used. The results are presented in six articles, showing that seagrass ecosystems are rich in seagrass species (13) and form an important part of the SES within the tropical seascape of the WIO. Seagrasses provide livelihoods opportunities and basic animal protein, in from of seagrass associated fish e.g. Siganidae and Scaridae. Research, management and education initiatives are, however, nearly non-existent. In Chwaka Bay, the goods and ecosystem services associated with the meadows and also appreciated by locals were fishing and collection grounds as well as substrate for seaweed cultivation. Seagrasses are used as medicines and fertilizers and associated with different beliefs and values. Dema (basket trap) fishery showed clear links to seagrass beds and provided the highest gross income per capita of all economic activities. All showing that the meadows provide social-ecological resilience. Drag-net fishery seems to damage the meadows. Two ecological studies show that artisanal seaweed farming of red algae, mainly done by women and pictured as sustainable in the WIO, has a thinning effect on seagrass beds, reduces associated macrofauna, affects sediments, changes fish catch composition and reduces diversity. Furthermore, it has a negative effect on i.a. women’s health. The two last papers are institutional analyses of the human-seagrass relationship. A broad approach was used to analyze regulative, normative and cultural-cognitive institutions. Cooperation and conflict take place between different institutions, interacting with their slow or fast moving characteristics, and are thus fundamental in directing the system into sustainable/unsustainable paths. Ecological knowledge was heterogeneous and situated. Due to the abundance of resources and high internal control, the SES seems to be entangled in a rigidity trap with the risk of falling into a poverty trap. Regulations were found insufficient to understand SES dynamics. “Well” designed organizational structures for management were found insufficient for “good” institutional performance. The dynamics between individuals embedded in different social and cultural structures showed to be crucial. Bwana Dikos, monitoring officials, placed in villages or landing sites in Zanzibar experienced four dilemmas – kinship, loyalty, poverty and control – which decrease efficiency and affect resilience. Mismatches between institutions themselves, and between institutions and cognitive capacities were identified. Some important practical implications are the need to include seagrass meadows in management and educational plans, addressing a seascape perspective, livelihood diversification, subsistence value, impacts, social-ecological resilience, and a broad institutional approach.

Full textCurrently, the mangrove oyster Crassostrea sp. is one of the most important fishery resources exploited by the artisanal fishery setor of the Cananéia estuary, responsible for the livelihood of 60 families of extractivists for some decades. The production system can be characterized as rudimental, involving the extraction in mangrove and its direct marketing or previous fattening in structures like trays. The oyster is marketed exclusively in natura and depuration is the only form of improvement, involving a few extractivists. The socioecological system of the oyster extractivism has been target of several interventions, since actions promoted by government agencies, to organize the production chain, till external pressures, like the market ones, which act on the management and commercial practices, affecting the sustainability of the activity. The objective of the present exertion was from the study of characteristics, management and marketing practices of the oysters extractivists groups from Cananéia, to identify the factors that affect the sustainability and to provide subsides to support the management of the activity. For that the socio-economical and productive profile of the users was studied, and the production of oysters in Cananéia, the local commercialization processes, the natural stock of oysters and the productive areas were analyzed. The identified groups of extractivists were compared, and the trends relating to the sustainability of the activity in the ecological, economic, social, technological and ethical dimensions were analyzed. The Mandira group, beneficiary of a considerable number of public interventions, was the group whose performance in the analysis of sustainability was comparatively better. In the extreme opposite, the Porto Cubatão group presented the worst performance in almost all dimensions studied, a fact associated with the small group experience in the activity. As the Porto Cubatão group much as all others located in intermediate position, even though tend to sustainability in specific dimensions, are more susceptible to crises caused by unexpected changes in the system. In the Mandira group, in spite of a better structure, the progress is fragile and it is necessary to consolidate it. The social, technological and ethical dimensions had negative influence on the trends of sustainability and should be considered as priorities in the actions of management. The aspects identified as strategic to improve the possibilities of sustainability of the activity were: encouraging the "fattening" activity of fattening of oysters as well as the replacement of the forms of sale box and desmariscada by production of oysters in dozens ; limiting the entry to the activity; restrainting the illegal commercialization and the processing technology and expanding the user s participation in the management of the activity.
Atualmente, a ostra de mangue Crassostrea sp. é um dos mais importantes recursos explotados pelo setor pesqueiro artesanal do estuário de Cananéia, responsável pelo sustento de cerca de 60 famílias de extrativistas há algumas décadas. O sistema produtivo pode ser caracterizado como rudimentar, envolvendo a extração do recurso no mangue e sua comercialização direta ou a engorda prévia em viveiros tipo tabuleiro. O produto é comercializado exclusivamente in natura e a depuração é a única forma de beneficiamento existente, envolvendo poucos extrativistas.. O sistema socioecológico do extrativismo de ostras tem sido alvo de diversas intervenções, desde ações promovidas por órgãos públicos, no sentido de organizar a cadeia produtiva, até pressões de origem externa, como as de mercado, as quais atuam sobre as práticas de manejo e comercialização, afetando as tendências relativas à sustentabilidade da atividade. O objetivo do presente trabalho foi, a partir do estudo das caraterísticas e práticas de manejo e comercialização dos grupos de extrativistas de ostras de Cananéia, identificar os fatores que afetam a sustentabilidade e fornecer subsídios para apoiar a gestão da atividade. Para isso, o perfil sócio-econômico e produtivo dos extrativistas de ostras de Cananéia foi estudado, bem como foram analisados a produção de ostras do município, os processos comerciais desenvolvidos na cadeia produtiva local, o estoque natural do recurso e as áreas produtivas. Os grupos de extrativistas de ostras identificados foram comparados, sendo analisadas as tendências relativas à sustentabilidade da atividade nas dimensões ecológica, econômica, social, tecnológica e ética. O grupo do Mandira, beneficiário de um considerável número de intervenções públicas, foi o grupo cujo desempenho na análise de sustentabilidade foi comparativamente melhor. Como contraponto, o grupo do Porto Cubatão apresentou o pior desempenho em quase todas as dimensões estudadas, fato associado à pequena experiência do grupo na atividade. Tanto o grupo do Porto Cubatão, quanto os grupos situados em posição intermediária, ainda que em dimensões específicas tendam à sustentabilidade, apresentam maior susceptibilidade a crises provocadas por mudanças inesperadas no sistema. No grupo Mandira, apesar de melhor estruturado, os ganhos alcançados são frágeis, havendo a necessidade de avanços que os consolidem. As dimensões social, tecnológica e ética tiveram influência negativa sobre as tendências da sustentabilidade, devendo ser consideradas como prioritárias nas ações de gestão da atividade. Os aspectos identificados como estratégias específicas de ação para melhorar as perspectivas da atividade quanto à sustentabilidade foram o incentivo à atividade de engorda de ostras; a limitação do ingresso à atividade; o incentivo à substituição das formas de venda na caixa e desmariscada pela produção de ostras em dúzias ; a coibição do comércio clandestino e ampliação do alcance da tecnologia de processamento pós-colheita e da participação dos extrativistas na gestão da atividade.

Full textThis work aims to perform a very important discussion to understand what is to be an artisanal fisherman when spaces modernization becomes vibrant and try to subdue their ways of working and living. As a result, its intended to stimulate reflections on the relationship between working and habitation for these subjects, who lives in a complex metropolitan context. For this task, will be elucidated key issues covering the daily lives of artisanal fishermen inhabiting in Pedra de Guaratiba neighborhood, located in the western area of the city of Rio de Janeiro (RJ), on the shores of Sepetibas Bay. Therefore, we will perform an attempt to comprehend analytically the poor agents, their life experiences and their conflicts with the social production of the metropolis. We will see that artisanal fishermen represent a category of extreme complexity and that is not even partially understood by the public institutions that govern your segment. This complexity is also part in the relationship between inhabiting and working in the lives of these subjects, thus becoming one of the pillars of their existence and hence of its own resistence. For the perception of these relations and the senses (social values) that animate the lives of these men and women, we seek to hold a methodology that the researcher makes himself more sensitive to recognize the links that unite these workers to their places of work and life, understanding the dynamics responsible for building the peculiarities that distinguish them (but do not exclude) to the other urban workers. Finally, we will come to understand that habitation and work for artisanal fishermen are inseparable pairs, which contribute to the categorys fortification in times of huge adversity

Full textFace à atual crise no setor pesqueiro mundial surgiram novas abordagens e estratÃgias para a gestÃo da pesca, tais como gestÃo ecossistÃmica, gestÃo compartilhada e unidades de conservaÃÃo marinha. A pesca artesanal, sobretudo na RegiÃo Nordeste, apresenta importÃncia incontestÃvel na produÃÃo de pescado e geraÃÃo de renda. Dentro deste arcabouÃo de novas possibilidades da gestÃo, este estudo objetivou prioritariamente avaliar os sistemas de pesca utilizados nos municÃpios de Aracati e Icapuà â CE, definindo aqueles que apresentam maior eficiÃncia na captura dos principais recursos pesqueiros segundo os aspectos econÃmicos e ambientais. O objetivo secundÃrio de maior relevÃncia consistiu na elaboraÃÃo de uma proposta de gestÃo para a pesca na regiÃo, baseado nos recentes conceitos citados anteriormente. Para isso, entre 2005 e 2009, foram realizados 312 controles do desembarque das frotas motorizadas e a vela, 25 entrevistas abertas e aplicaÃÃo de 238 questionÃrios. Os resultados evidenciaram que: os sistemas de pesca que empregaram embarcaÃÃes a vela demonstraram melhor desempenho econÃmico e ambiental em relaÃÃo aos sistemas de pesca operados por embarcaÃÃes a motor; a pesca realizada por embarcaÃÃes a vela corresponde Ãs caracterÃsticas da pesca artesanal, que consiste na distribuiÃÃo de renda, geraÃÃo de mais postos de trabalho, seguranÃa alimentar e uso mÃltiplo do ecossistema, permitindo que os recursos explotados nÃo sejam sobrecarregados por um esforÃo de pesca excessivo; o futuro da pesca realizada por embarcaÃÃes motorizadas està comprometido devido aos altos custos fixos e variÃveis de operaÃÃo e a atual baixa produtividade na plataforma continental dos municÃpios de Aracati e IcapuÃ
Given the current global crisis in the fishing sector new approaches and strategies for fisheries management have arised, such as ecosystem management, co-management and marine protected areas. Artisanal fisheries, mostly in the Northeast Brazil, have an undeniable importance for fish production and rent. Within this framework of new management possibilities, this study aimed primarily to evaluate the fishing systems carried out in Aracati and Icapuà counties, Cearà State, by defining those at the highest efficiency in catching their foremost fishing resources from the economic and environmental viewpoints. The secondary objective of greater importance was the development of a management proposal for the regional fisheries, based on the above-mentioned recent concepts. To this end, in the period from 2005 through 2009, 312 fish landings by the sail and motorized fleets were statistically controlled, 25 open interviews were made and 238 questionnaires applied. The results showed that: sailboat fisheries display a better economic and environmental performance than the motorboat fisheries; the fishing performed by sail boats correspond to the artisanal fisheries characteristics, as concerns income distribution, generating many jobs, food safety and multiple uses of the ecosystem. This way resources can be exploited but not burdened by an excessive fishing effort; the future of motorized fishing is threatened by the high fixed and variable operational costs and by the current low productivity in the continental shelf of Aracati and Icapuà counties

Full textThe aim of the present work is to study the factors that may explain the variability in distribution and intensity of artisanal fishing around a marine reserve, evaluate the reserve effect and analyze and assess the biological and economic effects of alternative configurations of a marine protected area. The results revealed that artisanal vessels used more fishing gears, but shorter, in high habitat diversity areas. The fishing yield depends of protection level, distance to marine reserve and diversity of fishing gears per unit area. The protection measures have had positive results on exploited fish populations and in the local economy. The increase of protected area surface, distributed on several no take zones at appropriate locations, a few kilometers apart, more than the reduction of the fishing effort, would have positive effects on the population of commercial fishes and the local economy.

Full textThis research has as its central theme the artisanal fishing practiced in Vacacaí River, RS. In the course of the study it was sought to characterize this activity, identifying its relationship with other economic activities that also use the river water, especially irrigated rice cultivation, from the vision of artisanal fishermen, and with the contribution of bibliographical and documentary research. From information obtained through official data of rice production and planted area, rainfall and altitudes of Vacacaí River, in the years 2004 to 2013, it was established the relationship between excessive consumption of water from irrigated rice cultivation and the decrease in the level of the river, one of the main problems pointed out by fishermen. Through three expeditions in which was traveled over 200 kilometers of Vacacaí Riverbed, where the water level allows navigation, it was mapped 64 rice fields irrigation pumps and another 24 disabled facilities. To identify Vacacaí fishing sites it was used participatory mapping, in which those interviewed artisanal fishermen made the recognition of their fishing grounds with the help of satellite images mosaics. That way seventeen fishing sites were mapped by Vacacaí fishermen, ten of which have irrigation pumps. These sites were considered potential areas of conflict between the two activities analyzed. Due to the size of the study area and the need to demonstrate the elements of analysis in detail, the final map containing this information had to be divided into three parts.
A presente pesquisa tem como temática central a pesca artesanal praticada no rio Vacacaí, RS. No decorrer do trabalho buscou-se caracterizar essa atividade, identificando sua relação com as demais atividades econômicas que também se utilizam das águas do rio, em especial a orizicultura irrigada, a partir da visão dos pescadores artesanais e com o aporte de pesquisas bibliográficas e documentais. A partir das informações obtidas com o uso de dados oficiais de produção de arroz e área plantada, pluviometria e cotas altimétricas do rio Vacacaí, entre os anos de 2004 a 2013, estabeleceu-se a relação entre o consumo hidrointensivo da orizicultura irrigada e a diminuição do nível do rio, um dos principais problemas apontado pelos pescadores. Através de três expedições onde foram percorridos os mais de 200 quilômetros do leito do rio Vacacaí onde o nível da água permite a navegação, foram mapeadas 64 bombas de irrigação das lavouras de arroz e mais 24 estruturas desativadas. Para se identificar os pesqueiros do Vacacaí foi utilizada a cartografia participativa, onde os pescadores artesanais entrevistados fizeram o reconhecimento dos seus locais de pesca com o auxílio de mosaicos de imagens de satélite. Assim, dezessete pesqueiros foram mapeados pelos pescadores do Vacacaí, sendo que em dez há a presença de bombas de irrigação. Estes locais foram considerados potenciais territórios de conflito entre as duas atividades analisadas. O mapa final contendo essas informações precisou ser gerado numa articulação de três partes, devido o tamanho da área de estudos e a necessidade de demonstrar detalhadamente os elementos de análise.

Artisanal fisheries are suffering a decline in most coastal areas in Brazil and in the world, which leads to ecological problems, such as the subtraction or even extinction of particular fish species, and to social problems, since fishermen no longer have their main source of livelihood. In Brazil, state intervention has not been sufficient to overcome these difficulties. Therefore, in order to face the crisis in the fisheries sector, an alternative form of management of common property resources arises in the literature. Intellectuals who study this issue have accepted shared management (collective management or co-management) as the best institutional arrangement alternative to avoid the perverse effects of over-exploitation. In this sense, the present work has as its main objective to analyse the shared management form implemented in the estuary of Lagoa dos Patos/Rio Grande do Sul (Brazil) through the creation of the Lagoa dos Patos Forum, in 1996. Since this management alternative is based on the relevant role played by the managing bodies and users of such resources, we decided to use the contributions of theoretical analysis on common property resources, focusing on shared management, as we believe that this form of co-management can contribute to the efficient and sustainable use of fishery resources.
A pesca artesanal encontra-se em decl?nio na maior parte das zonas costeiras do Brasil e do mundo, levando a problemas ecol?gicos com a subtra??o ou mesmo a extin??o de determinadas esp?cies de pescado e a problemas sociais, j? que os pescadores n?o disp?em de seu principal meio de subsist?ncia. No Brasil, a interven??o estatal n?o foi suficiente para superar essas dificuldades. Assim, diante da crise no setor pesqueiro, surge na literatura que trata dos recursos de propriedade comum, uma forma alternativa de manejo para esses recursos. A forma de gest?o compartilhada (gest?o coletiva ou co-gest?o), tem sido aceita por intelectuais que se dedicam ao tema, como a melhor alternativa de arranjo institucional para evitar os efeitos perversos da sobre-explora??o. Dessa forma, o presente trabalho tem como objetivo principal, analisar as forma de gest?o compartilhada implementada no estu?rio da Lagoa dos Patos/RS por meio da cria??o do F?rum da Lagoa dos Patos em 1996. Tendo em vista que essa alternativa de manejo fundamenta-se pelo relevante papel desempenhado pelos ?rg?os gestores e usu?rios de tais recursos, optou-se por utilizar as contribui??es da an?lise te?rica sobre recursos de propriedade comum, enfocando na gest?o compartilhada, acredita-se que essa forma de co-gest?o possa contribuir para o uso eficiente e sustent?vel dos recursos pesqueiros.
