Full textAbstract:
Engaging with fishers’ knowledge (FK) is increasingly valued in fisheries management (a) for FK’s utility for science and management, and (b) to improve the legitimacy of fisheries governance. Referring to both perspectives, this thesis examines: the nature and types of FK; FK’s relationship to scientific knowledge; and ‘extractive’ and ‘participative’ approaches taken to engage with FK. Chapters 3 and 4 compare fishers’ reports of catch rates with official landings data and underwater visual census (UVC). In Seychelles, contemporary reported catch rates and landings were consistent; but FK, landings and UVC perceived different trends over time. Over five western-Indian-Ocean countries, reported catch rates had no detectable relationship with UVC-measured fish biomass, despite a six-fold range in biomass. Such disparities between fishers’ and scientists’ perceptions provide opportunities to broaden the information base for monitoring; but challenge the legitimacy of science-based management in the eyes of resource users. Chapters 5 and 6 examine extractive approaches to engage FK. An interview-based stock assessment in Seychelles indicated that stocks were overexploited in contradiction to the qualitative perceptions of interviewed fishers. The extractive approach did not take account of fishers’ mental models which diverged from scientific assumptions about fish population dynamics and catch rates. In the North Sea, a postal questionnaire collected FK on stock trends, but had limited potential to influence scientific advice and satisfy fishers’ expectations, due to its limited scope T. Daw. How Fishers Count Page 3 and the lack of frameworks to utilise FK. Both cases illustrate the limitations of extractive methods, and the importance of engaging with more complex types of FK. Disagreements with science seem likelier, and more difficult to resolve for abstract types of FK. Extractive approaches can engage large numbers of fishers, but are less reliable and fail to improve governance. Participatory approaches, including collaborative research have greater promise for improving fisheries science and management.

Full textAbstract:
The economic behavior of Hawaii's longline fishers was analyzed using a cross-sectional and time-series dataset from 1991 to 1998. Three empirical essays were written analyzing (1) the technological and economic interrelationships in the longline fishery, (2) trip choice behavior, and (3) vessel entry, stay, and exit decisions of the longline fishers. Studies on the analysis of technical-economic interrelationships among species suggest that Hawaii's longline fishery is characterized by a joint production process. Substantial economic and technical interactions existed, as many of the cross-price elasticities were significant, indicating either complementary or substitution relations in production among species. There was insufficient evidence for rejecting the null hypothesis of input-output separability. Output supplies were independent of their own prices. Output elasticities to effort and stock levels were positive and significant. Fishers' trip (or fishery) choice behavior was examined by applying the utility theoretic mixed model. Fishers exhibited utility maximizing behavior by choosing the trip type that yields best return, but they appeared to be risk-averse by choosing trip alternatives with less varying return, ceteris paribus. They exhibited "inertia" in switching to an alternative trip. Stock abundance indices of major species significantly influenced the type of trip chosen. Older and smaller vessels were more likely to choose the tuna trip rather than the swordfish or the mixed trip. Finally, the vessel entry-stay-exit decision was analyzed by applying the multinomial logit (unordered) model. The probability of a vessel to stay (or exit) in the fishery increased (or decreased) for an increase in the annual earning potential of a fisher. The fleet congestion level had a significant impact on the vessel entry-stay-exit decision. Vessels were reluctant to enter to and willing to exit from the fishery for an increase in fleet size. Entry-stay-exit decision was also based on a perceived abundance in major species stock levels. A vessel was more likely to stay in the fishery when the vessel owner was a Hawaii resident or a vessel captain. Vessel age had little impact on the entry-stay-exit decision. Simulation of probabilities for both forms of choices was carried out under different fleet structure and stock conditions.

Full textAbstract:
The current trend towards marine spatial planning (MSP) worldwide impacts marine resource users, particularly in inshore fisheries. Understanding the spatial distribution of fishing activity and complex drivers of human behaviour may help elucidate and predict responses of fishers to changes in management. This thesis characterises fishers’ spatial behaviour and decision-making in the lobster (Homarus gammarus) fishery in Northumberland (UK). Information on the distribution of UK inshore fisheries activity is scarce, but arguably is critical to the success of future MSP and fisheries management. Chapter 2 develops a methodology using GIS to quantitatively compare the spatial coincidence of fishing effort distribution based on two different data sources. A statistically significant similarity is demonstrated between patterns of fishing activity indicated by observational and interview data. Spatial variability in lobster landings and inferred catch rates among fishing ports is examined in Chapter 3 using linear mixed effects models. A negative relationship was identified between measures of fishing intensity and landings at port level, yet this variability in landings is minimal compared to that among individual vessels, the causes of which are discussed. Based on quantitative and qualitative data collected through interviews with fishers, Chapters 4 and 5 investigate how the social context influences fishers’ decision-making and behaviour. Chapter 4 considers fishers’ perceptions in prioritising factors driving spatial decision-making. The findings are examined in light of evidence for territorial behaviour and discussed using theories of economic defendability and collective action. Social network analysis is applied in Chapter 5 to uncover information-sharing behaviour among fishers. Results highlight differences in network structure among ports, demonstrate a relationship between fishers’ position in information-sharing networks and their fishing success, and point towards the existence of social-spatial groups in fishing behaviour at sea. This thesis identifies inter-related factors driving decision-making, suggesting that an understanding of the social context shaping fishers’ spatial behaviour is important for developing appropriate management measures. Taking account of a fishery’s environmental and social characteristics is recommended for predicting fishers’ responses to changes in them.

Howard, Penny McCall. ""Working the ground" labour, environment and techniques at sea in Scotland." Thesis, University of Aberdeen, 2012. http://digitool.abdn.ac.uk:80/webclient/DeliveryManager?pid=185673.
Full textAbstract:
Drawing on ethnographic research undertaken at sea in north-west Scotland, this thesis builds a labour and class analysis of human-environment and human-machine relations. Fishing 'grounds' are constituted through metabolisms of labour as fishermen develop the affordances of their environments to make them productive. Places are constituted as fishermen transform them through their labour, judge them as significant through their productivity, and name them through the social process of collectively developing their affordances. Fishermen have developed complex techniques for extending their bodily senses far beneath the sea and working there. Tension is manipulated in these extended working practices, and control over these processes must be maintained in order for them to be carried out safely. However, social relations can affect the exercise of control and the practice of maintenance to shape tools and machines around one's body and according to one's intentions. Techniques for moving through the land and seascape include tools and electronic devices such as the GPS, and market and class relations affect what tools are developed and how skippers and crew relate to them. Market pressures are incorporated into the daily lives and subjectivities of commercial fishermen, and can determine the species that are targeted and what techniques are used. They have also affected the relation between fishing boat owners, skippers, and crew as a transition from shared ownership and shared payment to casual labour and low-waged migrant labour has taken place. Class relations affect fishing techniques, subjectivities, their exposure to violence and danger in their work, their control over their own practices and skills, the balance between their work and the rest of their lives, the cosmopolitainisation of their workplaces, and their ability to develop affordances according to their own interests. Work under capitalism is regularly experienced both as an alienating and as a relational, and people develop multiple subjectivities which they draw on as they decide how to act. An 'ideology of nature' has developed with capitalist class relations and division of labour which contributes to mainstream conceptions of the sea as a wilderness where human labour is only destructive.

Karnauskas, Mandy M. "From Physics to Fishers: A Multidisciplinary Approach to Evaluating Indicators of Fishery Benefits of Marine Reserves." Scholarly Repository, 2011. http://scholarlyrepository.miami.edu/oa_dissertations/704.
Full textAbstract:
Marine reserves are promising tools for fisheries management, and are especially suited for complex, multi-species fisheries. Recent work has focused on the design of reserves to achieve particular management objectives and on defining appropriate indicators for monitoring to determine whether these objectives are being met. In principle, there should be a strong correlation between biological, social and economic indicators that are all correlated with fish abundance and ecosystem health. In practice, different indicators are often inconsistent, and it is common for researchers and fishers to have conflicting opinions on how well reserves are meeting management goals. I suggest that these discrepancies are not necessarily due to conflicting opinions regarding management objectives, but rather that the inherent biases in different sampling schemes may cause different measures of the same parameter to be uncorrelated. For example, scientists tend to sample only snapshots in time and space in randomly chosen locations, while fishers sample over much greater temporal and spatial scales but in non-random locations. Furthermore, marine ecosystems are extremely complex, and failing to account for the full extent of this complexity may lead to erroneous measurement of biological trends. The purpose of this dissertation is to determine the causes of discrepancies between different types of indicators using a multidisciplinary approach. A detailed study of the Glover’s Reef Marine Reserve (GRMR) in Belize provides a basis for comparison. Chapters 2 to 4 of the dissertation focus on understanding how the GRMR has functioned to produce fisheries benefits, and elucidating some of the factors responsible for variation in species’ responses to reserve protection. Chapters 5 to 7 of the dissertation focus on comparisons of different indicators of changes in fish abundances, and explain the circumstances under which indicators may disagree. With a better understanding of the functioning of the GRMR based on both scientific and local knowledge, efforts can be made to develop more appropriate indicators, and these indicators can then be tested for use in other coral reef reserves worldwide.

Full textAbstract:
Fisheries are complex socio-ecological systems consisting of both human and ecological components. Managing fishery resources has almost always focused on ecological concerns without due consideration being given to the human dimensions. However, increasingly more scholars are recognising the need to integrate the human dimensions of fisheries management with the ecological concerns. Managing a fishery solely on the basis of ecological information will result in the management strategies being unsuccessful. Understanding the human dimensions is important as it provides insights into who participates in the fisheries industry, and what the behavioural patterns and motivations of the fishers are. This study focused on understanding the human dimensions of fishing at Zeekoevlei, focusing on who the fishers are and why they engage in fishing. It also addressed the source of conflicts at Zeekoevlei. The management of Zeekoevlei and fishing activities is also considered. A mixed methods approach, using a case study design, was adopted. The sample included fourteen fishers and six individuals involved on various levels of management of Zeekoevlei. Data-collection methods included the use of a structured questionnaire and semi-structured interviews. On the basis of this study, the demographics show that two types of fishers were found at Zeekoevlei – recreational and small scale. These fisher groups display contrasting socio-demographic profiles; however, a correlation between socio-demographics and motivations was observed. Recreational fishers appear to be white, educated males who are employed and engage in fishing for a sense of achievement, which is underpinned by the size of the fish. Small-scale fishers, on the other hand, are unemployed coloured males, with low levels of education and to this group of fishers the Zeekoevlei fishery system has an important function as it is used to diversify livelihoods. As with many fisheries, conflicts are prevalent at Zeekoevlei. These conflicts arise between fishers because Zeekoevlei has limited demarcated fishing spots and fishers display ownership over these spots; to exacerbate this situation, Zeekoevlei is located in an open reserve, which makes it easier for fishers to enter the reserve illegally. The management of the vlei appears to be based on recreational considerations with unclear measures to accommodate small-scale fisheries.

Resumo: A interação cotidiana com o ambiente marinho e com seus organismos leva pescadores artesanais a acumularem um conhecimento rico e particular acerca da biologia, da ecologia e da taxonomia de peixes. Assim, informações fornecidas pelos pescadores podem servir de subsídio para estudos ictiológicos, planos de conservação e manejo pesqueiro. Este estudo foi desenvolvido na Praia do Perequê, litoral de São Paulo, e é parte do projeto temático da BIOTA-FAPESP, subprojeto "Etnoecologia do Mar e da Terra na Costa Paulista da Mata Atlântica: Áreas de Pesca e Uso de Recursos Naturais". A Praia do Perequê está localizada na periferia do município do Guarujá e sofre as conseqüências da urbanização desordenada. O local abriga uma comunidade de pescadores que se dedicam à pesca do camarão e de peixes diversos. Os meus objetivos foram: traçar o perfil de pescadores de peixes e de camarão; inventariar as técnicas empregadas na captura das espécies estudadas; verificar e comparar com a literatura científica o conhecimento dos pescadores sobre habitat, dieta, reprodução e migração de peixes; analisar os critérios que os pescadores usam na classificação dos peixes. As informações foram obtidas com a utilização de questionários padronizados e fotos das espécies estudadas. Observei que os pescadores de camarão são em sua maioria migrantes provenientes de Santa Catarina, enquanto os pescadores de peixe são, na maioria, caiçaras nascidos no local. As técnicas de pesca são adequadas ao ambiente de captura do pescado e a escolha de iscas está relacionada com o hábito alimentar de cada espécie. Pescadores de peixe e camarão demonstraram conhecimento similar sobre técnicas de pesca. Tal similaridade pode ocorrer porque os dois grupos desenvolvem as atividades pesqueiras no mesmo local e entre as famílias de pescadores estão presentes membros que desenvolvem ambas as modalidades de pesca, o que pode propiciar a partilha do conhecimento. Em geral o conhecimento etnoecológico é condizente com o conhecimento científico. Tanto pescadores de peixe quanto os pescadores de camarão conhecem o habitat e a dieta das espécies mais capturadas, como: robalo, tainha, corvina, espada e garoupa. Ambos os grupos de pescadores fazem inferências sobre habitat e dieta a partir de aspectos morfológicos dos peixes. Conhecimentos sobre migração e reprodução por sua vez, foram mais escassos entre os pescadores estudados. Os pescadores apontam períodos específicos para ocorrência de tainha, corvina e anchova: a tainha e a corvina foram apontadas como espécies que se reproduzem no inverno, enquanto o robalo, o badejo e a garoupa se reproduzem em meses quentes. Essas espécies são de grande interesse comercial, o que pode explicar o conhecimento mais detalhado sobre elas em comparação com outras espécies menos conhecidas e de menor valor. Os pescadores do Perequê utilizaram a nomenclatura binomial especialmente em casos de ocorrência de mais de uma espécie por etnogênero. Os etnogêneros foram agrupados em etnofamílias principalmente de acordo com critérios morfológicos. As informações fornecidas apontaram particularidades que podem ser úteis no delineamento de planos de manejo adequados ao ambiente e à pesca local
Abstract: Artisanal fishermen can provide an elaborate and particular knowledge about biology, ecology and taxonomy of fish and about the ecosystem which they interact with. This knowledge is local and resulted from a continuity of resources use practices. Information supplied by fishermen can be the base for improvements of scientific research and to subsidis for conservation and fishery management plans. This study was conducted in the Perequê Beach, coast of São Paulo State. Perequê Beach is located in the periphery of the city of Guarujá, and suffers consequences of the disordered urbanization. Local people are dedicated especially to the shrimp and diverse fish fishery. The aims of this study were: to characterize local fishermen and fishery; to access the fishermen¿s knowledge concerning fish habitat, diet, reproduction and migration; to analyze the criteria that fishermen use in the classification of fish and to compare this knowledge with the scientific literature. Interviews using questionnaires and fish photographs were performed to obtain information regarding fishermen economical and social aspects and fish biology and ecology. The majority of shrimp fishermen are from Santa Catarina state while the fish fishermen are usually ¿caiçaras¿, local native. Fishery technologies and techniques are adjusted according to the environment and feeding habits of the target species. Both fish and shrimp fishermen demonstrated similar knowledge on fishes. Probably it can be related to the fact that both groups develop their activities in the same local and are members of families that develop the two modalities of fishery, sharing their knowledge. In general, the ethnoecological knowledge is in concordance with the scientific literature. Both fish and shrimp fishermen know the habitat and diet of the main fished species, as: snook (Centropomus spp.), mullet (Mugil platanus), croaker (Micropogonias furnieri), and groupers (Epinephelus marginatus e Mycteroperca acutirostris). Both fishermen groups make inferences on habitat and diet based on morphologic aspects. Knowledge on migration and reproduction was scarcer. The fishermen points out specific periods in respect to occurrence of mullet (M. platanus), croaker (M. furnieri) and bluefish (Pomatomus saltatrix). Mullet and croaker was suggested as a species that reproduces during the winter, while snook, and the groupers (E. marginatus e M. acutirostris) reproduce in hot months. These species have a great commercial interest that can explain the more detailed knowledge in detriment of others of lesser value. The Perequê fishermen use the binomial classification particularly in cases where there are more than one species in the same genus. The species were grouped in ethnofamilies mainly in accordance with morphologic criteria. The supplied information suggested particularities that can be useful in the management plans delineation in compliance with environment and its fishery place

Full textAbstract:
Les Maldiviens exploitent durablement le thon dans l'océan Indien depuis plus d'un millénaire, avec 20% des captures totales de thon de l'océan Indien actuellement débarquées aux Maldives. Après quatre décennies d'utilisation d'une moyenne de 55 dispositifs de concentration de poissons ancrés (DCPA-) répartis sur l'ensemble de l'archipel, cette thèse vise à améliorer nos connaissances sur l'écologie de la pêche au thon au sein du réseau de DCP des Maldives afin de mieux comprendre les moteurs de la durabilité de la pêche pour les années à venir. L'écologie du thon autour de ces DCP a été étudiée en recueillant les connaissances écologiques locales de 54 pêcheurs à la canne et en marquant acoustiquement 65 listaos et 57 albacores dans un réseau de 21 DCP instrumentés. La plupart des pêcheurs considèrent que des courants faibles, une température de la mer adaptée, des proies et des attractifs favorisent les agrégations tandis que des courants forts, des températures de la mer élevées et des conditions orageuses font que les thons quittent les DCP. Ils considèrent également que les thons ont tendance à rester associés aux DCP de 3 à 6 jours, ce qui est comparable aux résultats du marquage acoustique (de 2 à 5,5 jours en moyenne). Le marquage acoustique a montré que les thons n'ont pas de préférence spécifique dans la direction du mouvement, et que très peu de poissons se déplacent d'un DCP à l'autre. Par conséquent, les 55 DCP des Maldives ne fonctionnent pas comme un réseau mais semblent être relativement indépendants. Le réseau de DCP des Maldives peut être considéré comme une étude de cas pour examiner les avantages et les inconvénients des réseaux de DCP peu denses comme supports pour les pêcheries, tout en minimisant les impacts négatifs potentiels. Des recherches supplémentaires sur les aspects écologiques, sociaux et économiques de la pêche à la canne doivent être menées pour soutenir les Maldives dans leur gestion basée sur la scie nce.Mots clés: dispositif de concentration de poissons ancré, thons tropicaux, canne et ligne, Maldives, connaissances écologiques locales, temps de résidenceMaldivians have sustainably been exploiting tuna using hook and line in the Indian Ocean for over a millennium, with 20% of the total Indian Ocean tuna catches currently landed in the Maldives. After four decades using on average 55 anchored fish aggregating devices (AFADs) spread over the entire archipelago, this thesis aims to improve our knowledge on the fishery ecology of tuna within the Maldivian AFAD array in order to better understand the drivers of the sustainability of the fishery for the coming years. The ecology of tuna around these AFADs was studied by collecting local ecological knowledge from 54 pole and line fishers and by acoustically tagging 65 skipjack and 57 yellowfin tuna within an instrumented 21-AFAD array. Most fishers consider that slight currents, suitable sea temperature, prey and attractants enhance the aggregations while strong currents, high sea temperatures and stormy conditions make tuna leave AFADs. They also consider that tuna tend to stay associated with AFADs 3 to 6 days, which is comparable to results from acoustic tagging (from 2 to 5.5 days on average). Acoustic tagging showed that tuna do not have a specific preference in the direction of movement, and very few fish moved from one FAD to another. Therefore, the 55 AFADs in the Maldives do not act like a network but appear to be relatively independent. The Maldives FAD network can be considered as a case study to examine the pros and cons of sparse FAD networks as supports for fisheries, while minimizing potential negative impacts. More research on the ecological, social and economic aspects of the pole and line fishery must be conducted to support the Maldives in their science-based management.Keywords: Anchored Fish Aggregating Device, Tropical tunas, Pole and Line, Maldives, Local Ecological Knowledge, Residence Time

Honours thesis, Murdoch University, 2015. https://researchrepository.murdoch.edu.au/id/eprint/29398/.
Full textAbstract:
Artificial reefs have been constructed and deployed globally to enhance the productivity of aquatic habitats. In April 2013, two artificial reefs were deployed in Geographe Bay, Western Australia for the purpose of enhancing recreational fishing opportunities. These reefs are designed to create varied complex spaces and habitats, as well as to create shallow water upwelling to drive nutrients up into the water column. The deployment of artificial reefs in Australia has recently become the subject of specific focus of policy makers and regulators. Monitoring costs to meet legislative requirements can be prohibitive, however, a potential method to reduce these costs is to utilise volunteers from the general public to collect data (i.e. citizen science). Thus, the overall objective of this project was to determine whether recreational fishers could potentially provide an effective means for monitoring artificial reefs.
A small number of recreational fishers were provided with underwater video cameras and asked to record footage of artificial reefs and nearby natural reefs. Unfortunately, only limited amounts of data were received due to the lack of participation, unseasonal weather and the short timeframe of the project. However, enough videos were received to undertake a preliminary analysis of the differences in the characteristics of the fish faunas of the two types of reef. The results demonstrated that artificial reefs had much higher levels of mean and maximum abundance, number of species and ecological group affinities. However, multivariate statistical analyses did not detect any differences between the fish faunal compositions between artificial and natural reefs. This was due to the dominance of the labrid Coris auricularis and the large amount of variability between replicates.
Given the limited data provided by the above citizen science program, a literature review on other similar projects to evaluate the effectiveness of the citizen science components of the pilot project was completed and provided a set of key recommendations. These included enhancing the methods of contacting and recruiting volunteers, providing simplified and consistent instructions and consistent communication and engagement with volunteers.
Finally, Baited Remote Underwater Video (BRUV) systems, constructed from readily available materials, were deployed randomly around the Busselton artificial reef to test the applicability of this method for future use as a citizen science artificial reef monitoring tool. The video footage was analysed to determine whether there was a difference in fish assemblages between artificial reef modules and the surrounding area, i.e. videos observing areas in which artificial reef modules were, and were not, observed in the camera’s field of view. The results demonstrated that mean number of species and the number of benthic and epibenthic species were greater on footage recorded when the camera faced the modules. There was also a difference in the faunal composition. The footage observing artificial reef modules also exhibited 52.63% more recreational target species than surrounding areas. It was concluded that the BRUV technology employed here could be used, by citizen scientists, to monitor the fish faunas of artificial reefs. However, as this study has also demonstrated that there were significant differences in the characteristics of the fish faunas recorded depending on the direction the camera was facing, consideration is needed to design an unbiased and robust quantitative monitoring regime.
It is concluded that recreational fishers did not provide an effective means for monitoring artificial reefs during this project. This result, however, is a consequence of a lack of data stemming from an absence of volunteer engagement in a limited pilot project with a short time frame and unseasonal weather. This does not exclude the potential for using citizen scientists to monitor artificial reefs, following some changes in the methodology, technology and management of citizen science protocols, and thus it is possible to utilise recreational fishers as an effective means for monitoring artificial reefs. This project was subjected to restrictive and limiting factors but more importantly, discovered ways to overcome these issues by provided key recommendations on technology, methodologies and community engagement that should be followed to increase the effectiveness of using recreational fishers to provide sound scientific information in the future.

Full textAbstract:
Few empirical studies exist that compare regulation (R) and fishing crime (VL). The lack of information about R and VL effects stakeholder decision-making. Crime weakens conservation efforts and creates false baseline data. This furthers R and the cycle repeats. The purpose of this correlational study was to determine the statistical association between the number and type of annual commercial blue crab R and VL of the same. The Pearson's R correlation was used to analyze the data because it demonstrated the strength of each relationship. This quantitative study was grounded in enforcement theory. The data was public record and consisted of the number of R and VL issued yearly from the General Assembly of a Mid Atlantic's State Department of Natural Resources (MD-DNR). The intent was to correlate multiple decades, but the earliest available VL data began in 2009. The analysis uncovered divergent patterns. The correlation coefficient of 0.79644 confirmed laws from 2009 correlated positively with 2010 violations. Further analysis revealed a negative correlation for 2010 and 2011 that was indicated by a negative correlation coefficient of -0.3588 and -0.166. The mean average of VL was 12.5%. As restrictions keep increasing, the economic impact on local communities is substantial. This research has the potential to effect positive changes in restrictive harvest practices, record keeping of VL by Natural Resources of this Mid Atlantic State, and harvest reporting practices by crabbers. Sharing the findings with industry stakeholders may stimulate dialogue among stakeholders that answers why one type of regulation was violated more than another, encourage compliance by industry users, and improve conservation efforts to proliferate blue crab. This research contributes to future investigation of often-neglected variables that compromise conservation of blue crab.

Full textAbstract:
Marine protected areas (MPAs) are increasingly being used as tools for fishery management and marine conservation. This thesis investigates several aspects of the human dimensions of MPAs in Scotland with the purpose to contribute to the understanding of the attitudes of Scottish inshore fishers towards this management measure. Paper I reviews the literature on fishers’ attitudes towards MPAs. It reveals that most empirical work collects information on fishers’ attitudes towards three general issues of importance to MPAs: governance, conservation of biodiversity and the environment, and the impact of MPAs on fishing activity. Using data from surveys conducted with Scottish fishers, papers II, III, IV and V investigate fishers’ attitudes towards, and perceptions of, several issues of interest to MPAs. Plus, multivariate data analysis was used in all papers in order to identify which individual characteristics influence fishers’ attitudes towards, or perceptions about, the issues under investigation. Papers II, IV and V use data collected on a survey conducted with Scottish inshore fishers in 2006/07, while Paper III uses data from a survey conducted previously (in 2001/02). Paper II investigates Scottish inshore fishers’ perceptions about participation in the decision-making process. Results reveal that around half of the fishers perceived themselves to be informed about management, but most did not perceive themselves to be consulted or involved in the decision-making process. Papers III and IV investigate fishers’ attitudes towards labour mobility. More precisely, the papers investigate fishers’ willingness to leave the fishing sector, change to another gear or move to another area to remain fishing. Results reveal that fishers’ attitudes towards leaving the fishing sector were different in the two periods. In 2002 most fishers were willing to leave the fishing sector (Paper III) while five years later most were not (Paper V). Most importantly, both papers point to the importance of job satisfaction for fishers. Results point to the importance of understanding the economic, social and cultural contexts of the fishing industry for the success of measures and policies aimed at providing fishers with alternative job opportunities in order to counter impacts of displacement caused by the implementation of MPAs and reduction of the overcapacity of the European fishing fleets. Paper V investigates inshore fishers’ attitudes towards MPAs and issues of relevance to MPAs (e.g. compliance with, and enforcement of, rules, and state of resources). More precisely, the paper investigates the attitudes towards closed areas between users of different gears which are affected by closed areas in different ways. Results reveal that Scottish inshore fishers are not a homogenous collective; the attitudes towards closed areas differ among users of different gears.

Full textAbstract:
This study was initiated to assess the biological, ecological and sociological aspects of the blue crab, Callinectes sapidus, fishery associated with the Pascagoula River Estuary in southern Mississippi. Household surveys were conducted in the cities of Moss Point and Pascagoula, Mississippi, September 2010 to September 2011, to identify, describe and classify subsistence fishing activities associated with the estuary. A stock assessment of blue crab was conducted to determine how biological and environmental variability affect the people engaged in this subsistence fishery.
The study revealed two types of subsistence fishing occurring in the Moss Point/Pascagoula area. The first type involves fishing as a livelihood strategy based on economic dependence, and the second type involves fishing as a lifestyle choice based on economic independence. Both are based on customary and traditional patterns of local resource use and consumption and maintained by reciprocal kinship-based social networks.
The blue crab fishery in the Pascagoula River Estuary was highly variable and exhibited strong seasonal and spatial patterns in distribution and abundance. Subsistence fishers in the region have developed strategies to cope with this biological and environmental variability. These region-specific strategies include but are not limited to: fishing using multiple gears simultaneously (rod and reel and crab nets), freezing fish, relying on other natural resources including agriculture and wildlife, and generalized reciprocity.

Full textAbstract:
Small-scale fisheries are learning contexts of importance for generating, transferring, and updating ecological knowledge of natural environments through everyday work practices. The rich knowledge fishers have of local ecosystems is the result of the intimate relationship fishing communities have had with their natural environments across generations (see e.g. Urquhart and Acott 2013). This relationship develops strong emotional bonds to the physical and social place. For fishing communities and fishers – who depend directly on local ecosystems to maintain their livelihoods – fishing environments are natural places for living, working and defining themselves. Previous research on fishers’ ecological knowledge has mainly been descriptive, i.e., has focused on aspects such as reproduction, nutrition and spatial-temporal distribution and population dynamics, from a traditional view of knowledge that only recognises scientific knowledge as the true knowledge. By doing this, fishers’ ecological knowledge has been investigated separately from the learning contexts in which it is generated, ignoring the influence of social, cultural and historical aspects that characterise fishing communities, and the complex relationships between fishers and the natural environments they live and work in. This thesis investigates ecological knowledge among small-scale fishers living and working in the ecosystems of Lake Vättern and the Blekinge Archipelago (Baltic Sea) in Sweden and explores how ecological knowledge is generated with particular regard to the influences of work and nature on fishers’ knowledge of ecosystems. The aim of this thesis is to contribute to the knowledge and understanding of informal learning processes of ecosystem complexity among small-scale fishers. This knowledge further contributes to the research field of ecological knowledge and sustainable use and management of natural resources. It addresses the particular research questions of what ecological knowledge fishers generate, and how its generation is influenced by their fishing work practices and relationships to nature. The thesis consists of three articles. Article I focuses on the need to address the significant lack of theoretical and methodological frameworks for the investigation of the cognitive aspects involved in the generation of ecological knowledge. Article II deals with the need to develop theoretical, methodological and empirical frameworks that avoid romanticising and idealising users’ ecological knowledge in local (LEK), indigenous (IEK) and traditional (TEK) ecological knowledge research, by rethinking it as being generated through work practices. Article III addresses the lack of studies that explicitly explore theories linking complex relations and knowledge that humans form within and of ecosystems. It also addressed the lack of attention from environmental education researchers to theory and empirical studies of ‘sense of place’ research, with a particular focus on environmental learning. Research into the question of what ecological knowledge fishers generate shows differences in their ways of knowing ecosystem complexity. These differences are explained in terms of the influences of the species being fished, and the sociocultural contexts distinguishing fishers’ connection to the fishing profession (i.e., familial tradition or entrepreneurship) (Article I), but also by the fishing strategies used (Article II). Results answering the research question of how work practices influence fishers’ knowledge of ecosystem complexity show a way of rethinking their ecological knowledge as generated in a continuous process of work (Article II), thus, far from romantic views of knowledge. Results answering the research question of how fishers’ relationships to nature influence their knowledge of ecosystem complexity demonstrate the complex interconnections between psychological processes such as identity construction, proximity maintenance and attachment to natural environments (Article III). Finally, more similarities than differences between fishers’ knowledge were found, despite the variation in cases chosen, with regards to landscape, target species, regulations systems and management strategies, fishing environments scales, as well as cultural and social contexts.At the time of the doctoral defense, the following paper was unpublished and had a status as follows: Paper 2: Manuscript.

Full textAbstract:
The widespread practice of discarding dead fish is believed to negatively affect the sustainability of fish stocks. Between 2015-2019 a landing obligation, aiming to gradually eliminate this practice, is introduced in all EU fisheries. The Landing Obligation (LO) forces fishers to land all catch and requires monitoring at sea rather than on land, it is therefore anticipated to be particularly difficult to enforce. Based on this, the perceived legitimacy of the policy among fishers is believed to be of greatest importance to ensure successful implementation. To create an understanding of fishers’ commitment to uphold the LO, this study examines Swedish demersal West Coast fishers’ perceived legitimacy of the LO through qualitative interviews. In the interviews Swedish fishers expressed a dual commitment towards upholding the LO. On the one hand, the fishers are overall highly committed to avoiding unwanted catch, which is shown by a positive attitude towards the use and development of selective gear. On the other hand, many are sceptical to the practical formation of the LO, which is at times perceived as incoherent with the fishers’ ecological understanding, as well as with individual fishing practices and policy aims. Finally there are indications of a lack of trust from fishers in the knowledge and intentions of fishery managers, which creates a barrier for commitment to any fishery policy. For the LO to succeed it is important that fishers develop their practices to avoid unwanted catch. Therefore, it is important to facilitate fishers’ commitment to the policy’s aim rather than merely focusing on compliance with the policy rules.

Full textAbstract:
Artisanal fisheries are a key source of food and income for millions of people worldwide. However, unmanaged or excessive fishing activity can lead to declining returns for fishing effort and livelihood insecurity, and adversely impact wetland ecosystems. Management interventions such as protected areas and temporal closures may improve fishery sustainability and reduce environmental degradation, but often carry costs for fishers. Understanding predictors of fishing behaviour would allow conservation planning to minimise the adverse impacts of interventions, increasing the likelihood of fisher support of change. However, factors influencing fishers’ behaviour are rarely identified or taken into account when implementing conservation actions. Madagascar’s Lake Alaotra wetland supports the nation’s largest and most productive artisanal freshwater fishery, and provides critical habitat for endemic wildlife. Local fishers depend on the fishery for livelihood throughout the year. Catch-monitoring interviews, semi-structured interviews, focus groups, and follows were conducted over 16 months with 784 fishers at Lake Alaotra to understand the socioeconomic dynamics of the fishery. Although information from the fishers was sometimes imprecise, participatory monitoring methods engaged fishers and improved understanding of system dynamics. Linear mixed models confirmed that proposed restricted areas and temporal closures would generate direct short-term costs through reduced catch sizes, which vary between gear types. Socioeconomic data, spatial distribution of fishing effort, and fishers’ evaluations of management scenarios were used to explore alternative strategies. The conservation planning tool Marxan was used to identify reserve networks capable of achieving conservation goals while minimising adverse impacts for fishers. The research demonstrates that: interventions can have unequal impacts on local people: information about costs and benefits of interventions can produce more realistic and implementable conservation plans: and actively engaging fishers and understanding their spatial behaviour at relevant scales is critical for managing fisheries sustainability and promoting effective long-term conservation of freshwater ecosystems.

South Africa’s coastal environment is characterized by an increasing network of Marine Protected Areas (MPA), with the purpose of conserving fisheries resources and marine biodiversity. The coast is also home to over a hundred rural small-scale fisher communities, such as the community at Struisbaai Noord, which are considered to be marginalised communities heavily dependent on marine resources for their food security and income needs. The small-scale fisher community at Struisbaai Noord is one of several fisheries operating in the waters off the coast of Struisbaai. The others are: a migratory commercial line fishery, boat and shore-based recreational fishery, chokka squid commercial fishery, and commercial trawlers. The overall aim of this study is to understand the human (social, economic, cultural and institutional) dimensions of the small-scale fisheries sector in Struisbaai, with a particular focus on the livelihood strategies that fishers in this community employ, in order to inform future marine protected area planning in the Agulhas region.

Full textAbstract:
Bibliography: pages 220-234.This thesis examines the historic right of the Kalk Bay fishermen to occupy the area and exploit the marine resources of False Bay. It attempts to provide the historical base absent from anthropological, and other, works which have focussed on the area. In recent years, the local handline fishing community has faced destruction by a complex web of political, social and economic forces. This work shows that these have simply been new challenges in a long line, albeit the most serious, faced by the fisherfolk of Kalk Bay. The study begins with an examination of human settlement, and the origins of fishing, in Kalk Bay to the late nineteenth century. This is followed by an analysis of the organisation of the local fishing industry at the close of that century. These two chapters provide the backdrop for discussion of the commercialization of the local fishing effort, between 1890 and 1913. The fourth chapter deals with the establishment of the modern fishing industry in Kalk Bay, from 1913 to 1939. The thesis concludes with a brief examination of the community to the 1980s. Major findings are that the local fishermen of today are the product of a cultural and economic tradition stretching back thousands of years. By the late nineteenth century, the rhythm of life in the area was being rapidly changed by its incorporation into the social and economic orbit of greater Cape Town. Over the main period covered by the thesis, the local fishermen, as a result of their race and class, occupied the weaker position in conflicts with local authorities, the state and capital. However, they were able to fight dependence upon a single buyer and growing pressures for their proletarianisation and managed to maintain their independence as petty-commodity producers. The independence of the fisherfolk was nevertheless maintained at the expense of increasingly depressed local markets for their fish. Since the Second World War, the escalating political, social and economic subordination of the fisherfolk has progressively threatened the existence of the handline fishing industry and the fishing community at Kalk Bay. However, should racial ideologies and commitment to monopoly capitalization of the industry be set aside by the state, the Kalk Bay fisherfolk could survive, albeit in altered and diminished circumstances.

Full textAbstract:
This study from the onset sought to explore, through a postcolonial critique, the meaning ascribed to child labour by fishers in a fishing community in Ghana. The purpose was to inform practice in social work so that social justice might be achieved for working children and their parents. However the study expanded, methodologically and theoretically, to preliminarily include a psychoanalytically informed psychosocial and discursive approach, extending the postcolonial critique to develop a nuanced understandings of the fishers' lived experience of, and responses to, children's work. Distinct from the dominant reductionist and positivistic etiologic understandings of child labour, this approach neither derides child labour as morally reprehensible and unequivocally dangerous, nor romanticises its beneficial aspects and links to cultural and traditional beliefs and practices (see Klocker, 2012). Instead, enables understanding of the fishers as ‘defended subjects' who invest in certain discourses as a way of defending against their vulnerable selves. It also affords a critically reflexive understanding of myself as a ‘defended researcher', owing to my semi-insider position as a former child labourer, and of the impact of this on my research relationships and findings. The study is intended to inform social worker practices in order to deal with complex situations concerning the relationship among fishers and their children paying equal attention both to the inner and the social circumstances of the fishers (Wilson, Ruch, Lymbery, & Cooper, 2011). In this regard it is inspired by Mel Gray's (2005) contention that social work practice should be shaped by the extent to which local social, political, economic, historical and cultural factors, as well as local voices, mould and shape social work responses. The study is conducted using critical ethnographic design that draws on the lived experiences of 24 fishers. Attempts were made to explore the fishers' experiences using psychoanalytically informed method (FANI) in addition to other conventional methods. The study highlights the fishers' use of narratives of slavery to explicate child labour. It focuses on the relationships that the fishers' have developed with their children and with the laws surrounding the use of children in work. It gives an indication of how the fishers' violently and aggressively relate with their working children. It also highlights the fishers' rejection of the laws surrounding child labour as being foreign and an imposition which excludes customary laws. The study further examines the identities the fishers developed in relation to laws that regulate them and children's work. It suggests that others see the fishers as powerless subjects who don't matter. It also underscores my shame and worries as a researcher considered by the fishers as an ‘educated elite' who works for ‘white people'. It further highlights how I provided self-justifying explications to defend myself as a researcher. The findings imply that solutions to child labour need to be localised paying equal attention to both the psyche and the social life of the fishers. They speak to the imperative for critical review of social workers/NGOs practices taking into account the unconscious processes that go on between fishers as parents and social workers as service providers. This thesis introduces a psychosocial dimension and insight into debates on child labour in Ghana.

Full textAbstract:
The decline of the world’s fisheries, and the inability of traditional management frameworks to maintain them, has led managers to adopt new, alternative management frameworks. Alternative management frameworks include marine protected areas (MPA) and dedicated access privileges (DAP). The use of such frameworks has often been shown to be quite unpopular, especially with commercial fishers. In this thesis, commercial fishers’ preference for alternative management frameworks is examined in the context of the unique multispecies fisheries of the Florida Keys. By surveying commercial fishers, it was found that the size of operation plays no role in affecting fisher perception of dedicated access privileges. Furthermore, fishers who are organized are less likely to support dedicated access privilege frameworks. Finally, the fishing industry does not support the implementation of dedicated access privileges in the Florida Keys. These findings can provide inputs for managers in developing effective management plans in the region.

Fishers are among the biggest commercial resource users in the marine environment. In order to meet international, national and local policies, the UK has to designate a suite of marine protected areas (MPAs) and reach marine renewable energy (MRE) targets. Inevitably, there will be conflict between these two industries and marine conservation. This study uses a multi-disciplinary approach to examine evaluate the suitability of various sources of data, which could be used to detect, assess, and ultimately predict, fishing effort displacement within the different sectors of the > 15 m fleet in the South West of the UK. Gear-specific Vessel Monitoring System (VMS) data from 2005-2008 was used to assess potential effort displacement due to Haig Fras, a proposed MPA and Wave Hub, a marine renewable energy installation (MREI). The spatial distribution of fishing activity was highly heterogeneous and distinct areas of intense fishing could be identified for all gear-types. A closure of Haig Fras would have the greatest impact on gillnetters. Scallop dredgers also occasionally use the area. The current closure at Wave Hub has the greatest impact on potters and whelkers whose geographic specialisation is most pronounced and who use the area extensively. Longliners also use the area disproportionately would be affected. A simple index of variability was developed in order to determine baselines and two other sources of data were used. High resolution seabed data and low resolution catch data. A semi structured interview was conducted with forty fishers to elicit further information on the challenges, barriers to progress and priority issues in relation to MRE those fishers face. The theme of discontent with the consultation process scored highly throughout. Fishers’ Knowledge (FK) another source of data also scored highly, although further work must be carried out to identify what aspects of this data are useful in assessment of fishing effort displacement.

Full textAbstract:
This thesis presents a case study conducted in 1994 concerning the effects of fishery management regulations on the Native village of Old Harbor, Alaska. Access to the traditional livelihood of harvesting marine resources has profound implications for the sustainability of the economy of Alaska's rural Native villages. The institution of the limited entry system in 1975 caused the transfer of commercial salmon fishing rights away from some Native fishermen and a reduction in local fishing jobs. Although the alternatives may have had similar or worse effects on the village, limited entry is perceived as a major cause of economic and social dysfunction. One of many factors that has integrated remote villages into the global market economy, it has exacerbated the uneven distribution of wealth in the community and contributed to a growing gulf between fishing as a business and a lifestyle.
