Abstract Mathew, S. 2011. Fishery-dependent information and the ecosystem approach: what role can fishers and their knowledge play in developing countries? – ICES Journal of Marine Science, 68: 1805–1808. An ecosystem approach to fishery management is as much a mechanism to deal with the impact of fishing on targeted, associated, and dependent fish stocks, and on the habitat, as it is to deal with the impact of habitat degradation from natural and anthropogenic factors on fishing. In developing countries, often with little institutional capacity for generating timely and reliable information for managing fisheries, effective integration of the knowledge possessed by fishers and their communities regarding, for example, oceanographic, biological, economic, social, and cultural aspects can contribute to an ecosystem approach to fisheries. The challenge is to identify and validate such knowledge and to create policy and legal space to integrate it into management, also drawing upon good practice in industrialized countries. An attempt is made to identify such knowledge, to discuss its salient aspects, and to look at the conditions under which its practical value can be enhanced and integrated into formal fishery-management systems in developing countries.

<p>The Republic of Indonesia Fisheries Management Region is an area that intended for controlling the fisheries management activities. However, the potential value of fisheries in WPP-RI 711 has been decreasing starting from 2016 to 2017. The problems are about fisheries resource management activities in the region which are then linked to government policy control. This study seeks to determine the development of fisheries resource production in FMR-RI 711, the level of utilization based on management with the MSY and MEY models, and also control of sustainable fisheries policies. This study uses experimental quantitative methods with the Schaefer, Fox and Gordon models. Data obtained came from fisheries resource groups and data samples were taken from shrimp groups. The results of the analysis show that the average development of fisheries resource production in FMR-RI 711 has decreased even experienced overfishing in the commodity of Small Pelagic Fish and Crustaceans. The Schaefer model is considered the most appropriate because it has a determination coefficient value of 42.9% and has an optimum effort value of 179 trips/year, with the MSY value obtained at 3.8520 tons/year. The policy controls carried out so far are still very lacking and need to take firm action from the government in overcoming fisheries problems that are overfishing. Therefore, it can be concluded that fisheries management in FMR-RI 711 has not run optimally, then fisheries management should also be carried out by considering the economic aspects of fisheries, besides it also needs serious efforts on fisheries supervision and the development of a cost model to maintain resources from overfishing.</p><div><p class="Els-keywords">Keywords: Fisheries management, Fisheries policy, FMR-RI 711</p></div>

This work was carried out in the Enseada da Baleia and Vila Rápida communities. Data was provided by the Co-Management Committee of the Cardoso Island State Park (PEIC) on manjuba fishery management, technique and strategies used by the fishermen, as well as locally accumulated knowledge. Based on the results, social, ecological, and economic aspects of this type of fishing were analyzed. The importance of the accumulated knowledge and experience of this community, as well as the limitations imposed by local fishing gear, was concluded to be essential in conserving manjuba fishery conditions in the area. Industrial fishing, relevant state legislation, and market conditions were found to be the main obstacles to local fishery. Various proposals are suggested for manjuba fishery management, with emphasis on the need for fishing community participation in whatever measures are ultimately implemented.

Full textAbstract:
The design of intelligent management plans for marine fisheries requires recognition of the uncertainty of marine systems when assessing fishery performance through the use of bio-economic indicators. The uncertainty causing variability in the estimated values of the bio-economic indicators is incorporated through the use of Monte Carlo analysis to estimate the probability of exceeding limit reference points. To account for natural variability and other sources of uncertainty, estimates of appropriate fishery bio-economic indicators are needed in order to re-evaluate the fishery periodically and establish new reference points and corresponding management strategies. This paper concentrates on this aspect of the management process. It presents a classification of indicators in accordance with the level, change and structure framework. Alternative approaches to deal with risk and uncertainty in data-limited management contexts are discussed.

Abstract While international agreements and legislation call for incorporation of four pillars of sustainability, the social (including cultural), economic and institutional aspects (the ‘human dimension’) have been relatively neglected to date. Three key impediments have been identified: a relative lack of explicit social, economic and institutional objectives; a general lack of process (frameworks, governance) for routine integration of all four pillars of sustainability; and a bias towards biological considerations. Practical integration requires a ‘systems’ approach with explicit consideration of strategic and operational aspects of management; multidisciplinary or transdisciplinary evaluations; practical objectives for the four pillars of sustainability; appropriate participation; and a governance system that is able to integrate these diverse considerations in management. We challenge all involved in fisheries to immediately take five practical steps toward integrating ecological, economic, social and institutional aspects: (1) Adopt the perspective of the fishery as a ‘system’ with interacting natural, human and management elements; (2) Be aware of both strategic and operational aspects of fisheries assessment and management; (3) Articulate overarching objectives that incorporate all four pillars of sustainability; (4) Encourage appropriate (and diverse) disciplinary participation in all aspects of research, evaluation and management; and (5) Encourage development of (or emulate) participatory governance.

Full textAbstract:
Marine fish populations can be vulnerable to overfishing, as a response of their life history, ecology, and socio-economic aspects. Vulnerability assessments, in this regard, can be used to support fisheries decision-making by aiding species prioritization. Assessments like Productivity–Susceptibility Analyses are well suited for multispecies fisheries, with low gear selectivity and insufficient fishery-independent and dependent data. Using this method, we assessed local vulnerability of the Galapagos grouper (‘bacalao’; Mycteroperca olfax) and compared it with other phylogenetically-related species caught in the Galapagos’ handline-fishery. Bacalao is an overfished regionally endemic fish species, characterized by low resilience, high market and cultural value and high spatial overlap with the fishery. Our results suggested that bacalao is a species of high management priority, requiring urgent measures to prevent fisheries’ collapse. In addition, if current fishing pressure persists, other related species may become threatened in the near future. We also evaluated different management scenarios using this approach. Results suggested that the inclusion of additional no-take zones in the marine reserve, comprising key nursery habitats (such as mangroves) and spawning aggregation sites, would be necessary to reduce species vulnerability and to benefit other related species. Improving enforcement and fishers’ compliance are essential to guarantee the effectiveness of these measures.

Full textAbstract:
Despite the many scientific and public discussions on the sustainability of fisheries, there are still great differences in both perception and definition of the concept. Most authors now suggest that sustainability is best defined as the ability to sustain goods and services to human society, with social and economic factors to be considered along with environmental impacts. The result has been that each group (scientists, economists, non-governmental organizations (NGOs), etc.) defines “sustainable seafood” using whatever criteria it considers most important, and the same fish product may be deemed sustainable by one group and totally unsustainable by another one. We contend, however, that there is now extensive evidence that an ecological focus alone does not guarantee long-term sustainability of any form and that seafood sustainability must consistently take on a socio-ecological perspective if it is to be effective across cultures and in the future. The sustainability of seafood production depends not on the abundance of a fish stock, but on the ability of the fishery management system to adjust fishing pressure to appropriate levels. While there are scientific standards to judge the sustainability of food production, once we examine ecological, social, and economic aspects of sustainability, there is no unique scientific standard.

The economic land management of unprotected floodplain areas is possible only if considered jointly with protected floodplain areas, for which facility fisheries provide a solution. One solution could be that a part of the natural fish increment of the spawning-grounds on unprotected floodplains be raised in protected side fishponds and then later sold. This kind of fishery utilization is also favourable from economic, conservationist and flood protection aspects.

Full textAbstract:
At the Second International Billfish Symposium in Kona, it was reported that little was known about the social and economic aspects of recreational billfish fisheries. There was plenty of background, some good questions, but few answers. There had been little history of social science involvement in fisheries management at the time and even less in billfish fisheries. Whether authorized or not, fishery management decisions worldwide are going to be made on the basis of ‘best available’ social and economic understanding. Unfortunately, the values held by many in the billfish angler community are not likelyto be well represented in the mix for various reasons. Research in the USA and in Latin America over the past 13 years hasprovided an understanding of the billfish angler constituency, its commitment to catch and release and support for resource conservation, its local and regional impacts on tourism economies, and its willingness-to-pay above andbeyond trip costs (a measure of user value) in the US Atlantic, Puerto Rico, Costa Rica and Mexico Pacific. Although knowledge of the recreational billfish fishery has improved, comparatively little is known about the social and economic benefits associatedwith commercial (direct and bycatch) billfish fisheries. With little more than dockside prices available in many localities, it is difficult to know their value in comparison with recreational fisheries and the possible trade-offs associated with various management measures. In addition to describing what is still not known, this paper will identify a future research agenda in this area.

Pengertian dasar untuk pengelolaan perikanan terkait dengan fungsi fungsi biologi, sosial, teknologi, ekonomi serta lingkungan sumber daya sebagai komponen yang saling berhubungan untuk terjaminnya pengelolaan secara berkelanjutan. Stok ikan, ekosistem dan masyarakat nelayan merupakan salah satu kesatuan yang tidak dapat dipisahkan dalam sistem yang dinamis, dimana perubahan taktik dan strategi pemanfaatan masih merupakan suatu hal yang banyak dilakukan dalam rangka penyesuaian antara faktor teknis dan ekonomis yang sering kali mengabaikan pertimbangan bio-ekologi sumberdaya ikan. Sasaran pendekatan dan kebijakan pengelolaan perikanan di berbagai negara sudah mulai berubah, diawali dengan pendekatan memaksimalkan tangkapan tahunan dan ketenaga-kerjaan menuju ke konservasi dan pengelolaan berbasis pelayanan ekosistem. Konsep pengelolaan berbasis masyarakat dan ko-manajemen masih terbatas pada pengelolaan kawasan konservasi dan habitat terumbu karang. Adanya kesenjangan dan perbedaan antara kepentingan kawasan konservasi sebagai akibat kurangnya pemahaman kolektif terhadap tujuan pengelolaan, dan kerapkali menyebabkan aktifitas perikanan tangkap sebagai bagian dari kebutuhan ekonomis berbenturan dengan fungsi kawasan konservasi dalam jangka panjang. Pengendalian upaya penangkapan dan memahami dinamika perikanan, serta mengelola nelayan menjadi prioritas untuk pengelolaan sumber daya ikan, sedangkan konsep pengelolaan berbasis masyarakat dan ko-manajemen ditempatkan sebagai pelengkap untuk menutupi kelemahan aspek legal wilayah pengelolaan perikanan atau sumber daya ikan.Basic understanding of fisheries management related to biology, social, technology and economic function of fish resources. Fish stocks, ecosystem and fishers community are the integrated component under the dynamic of fisheries system, where as changing and on fishing tactic and strategy still exist to adjust between biology, technics and economics aspects. It is obvious that all technological creeps oftenly ignored the bio-ecological consideration of fish resources. The fisheries management and its policy were gradually shifting from maximize the catch, job opportunity become conservation and ecosystem based fisheries management. The concept of community-based management and co management is still limited to the management of conservation areas and coral reef habitats. The existence of gaps and differences between the interests of the conservation area as a result of a lack of understanding collective to the management objectives and often causing fishing activities as part of the economic needs clash with the function of conservation areas in the long term. Control efforts to capture and understand the dynamics of fisheries, as well as managing fishing is a priority for the management of fish resources, while the concept of community-based management and co management issued as a supplement to cover the weakness of legal aspects of the fishery management area or fishery resource.

Information source preferences of small-scale fishers can play a role in decision-making processes and affect the sustainability of small-scale fisheries. In this respect, determining useful communication tools to eliminate the information gaps and lack of information of fishers is important for sustainable and effective fisheries management. The purpose of this study was the determination of the preferred source of information and priorities of the small-scale fishers who operate along the Aegean Sea coast of Turkey. Data were collected from a random sample of 278 small-scale Turkish fishers located along the Aegean coastline via face-to-face interviews. Information source preferences of fishers were determined by Repertory Grid Technique. In the analysis, obtaining information about fisheries focused on three criteria such as marine ecology, fisheries technology, and fisheries policies. The level of importance given by fishers for each criterion was determined. Fishers prefer to get information from other fishers, followed by fishery cooperatives, and their own experiences (χ2 (11, n = 278) = 1305.920, P < 0.001). Fishery cooperatives are the closest organizations to fishers. The use of cooperatives as a source of information can be interpreted as an element that can facilitate access to information when evaluated through the “availability” of behavioral economics. Fishery cooperatives, which stand out in fishers’ information source preferences, have the potential to be a valuable source of information in all aspects. The results of the research are thought to benefit researchers from non-governmental organizations, research institutes, and universities that carry out national and international projects with fishers.

The tropical ecosystem had high biomass productivity but still less in economic values. Integrated Bio-cycle Farming System (IBFS) was an alternative system that harmoniously combines agricultural sectors (agriculture, forestry, animal husbandry, fishery, plantation estate, horticulture) and non-agricultural aspects (industry, household, infrastructure, the marketplace) on integrated ecological management. The key characteristics of IBFS developed in UGM University Farm were (i) an integration of agriculture and non-agriculture sector, (ii) value of environment, esthetics and economics, (iii) rotation and diversity of plants, (iv) artificial and functional biotechnology, (v) management of closed organic cycle, (vi) ecosystem health management, (vii) agropolitan concept, (viii) specific management of plant and (ix) holistic and integrated system. The management of cycle of energy, organic matter and carbon, water, nutrient, production, crop, money conducted through 9R (reuse, reduce, recycle, refill, replace, repair, replant, rebuild, reward) to obtain optimal benefits for global environment and livelihood. The system had a sustainable multifunction and multi-product (food, feed, fuel, fiber, fertilizer, biopharma, water, energy, oxygen, edutainment, eco-tourism). They would meet the expected basic need for daily-, monthly-, yearly- and decade’s income at short-, medium- and long- term periods. IBFS was a good prospect for sustainable economic, environmental, and socio-culture aspects.

Full textAbstract:
In Canada our approach to the management of fish resources and their habitats has been in turmoil for several decades, especially during the past decade. That many direct and indirect users of the aquatic ecosystems have been and are continuing to make improper use of them is widely recognized by the public and in formal government policies. Some of the improprieties have been reduced while others are intensifying. How to reduce all improprieties and how to foster meliorative husbandry are being addressed with respect to ecological, social, economic, and political aspects of the man–nature ecosystem. Reconsideration of all rights to the use of fish and their habitats, where the "rights" may be de jure and formally sanctioned, or de facto and informally accepted or imagined and illegal, is leading to proposals that legitimate rights be clarified and be allocated in more explicit and open ways. As allocative devices both the market system and processes of community-level negotiation are being developed further, and the centralized administrative (or bureaucratic) device is being reformed to accommodate the greater use of complementary devices. These issues are here explored with respect to intrajurisdictional problems and opportunities in Canada.

An interdisciplinary team of academics and representatives of fishing fleets and government collaborated to study the emerging requirements for sustainability in Canada’s fisheries. Fisheries assessment and management has focused on biological productivity with insufficient consideration of social (including cultural), economic, and institutional (governance) aspects. Further, there has been little discussion or formal evaluation of the effectiveness of fisheries management. The team of over 50 people (i) identified a comprehensive set of management objectives for a sustainable fishery system based on Canadian policy statements, (ii) combined objectives into an operational framework with relevant performance indicators for use in management planning, and (iii) undertook case studies that investigated some social, economic, and governance aspects in greater detail. The resulting framework extends the suite of widely accepted ecological aspects (productivity and trophic structure, biodiversity, and habitat–ecosystem integrity) to include comparable economic (viability and prosperity, sustainable livelihoods, distribution of access and benefits, regional–community benefits), social (health and well-being, sustainable communities, ethical fisheries), and institutional (legal obligations, good governance structure, effective decision-making) aspects of sustainability. This work provides a practical framework for implementation of a comprehensive approach to sustainability in Canadian fisheries. The project also demonstrates the value of co-construction of collaborative research and co-production of knowledge that combines and builds on the strengths of academics, industry, and government.

Abstract The northern shrimp (Pandalus borealis L.) stock in the Skagerrak is shared by Sweden, Norway, and Denmark. Although the fishery is regulated by an annual agreement between the EU and Norway, there are also national regulations as well as differences in fleet composition and shrimp markets. In early 2014, the World Wildlife Fund gave all Skagerrak shrimp a red light in their seafood consumer guide, which led to an extensive debate, especially in Sweden, about the sustainability of this fishery. The aim of this study was to quantify a set of indicators that together give a broad picture of the sustainability of the three fisheries to provide an objective basis for a discussion on needed measures. The different indicators concerned environmental, economic or social aspects of sustainability and were quantified per tonne of shrimp landed by each country in 2012. The Danish fishery was most efficient in terms of environmental and economic indicators, while the Swedish fishery provided most employment per tonne of shrimp landed. Fuel use in all fisheries was high, also when compared with other shrimp fisheries. Interesting patterns emerged, with smaller vessels being more fuel efficient than larger ones in Sweden and Norway, with the opposite trend in Denmark. The study also demonstrated major data gaps and differences between the countries in how data are collected and made available. Various improvement options in the areas data collection and publication, allocation of quotas and enforcement of regulations resulted. Product-oriented studies could be useful to follow-up performance of fisheries over time and to identify how to best utilize the Skagerrak shrimp stock. This could involve evaluating novel solutions in terms of technology and management, based on current and future scenarios aiming to maximize societal benefits generated from this limited resource, at minimized environmental impacts.

The results of fisheries are effects of important economic and social importance. Therefore, the problems of the development of the fishing industry occupy a special place in economic policy at all levels of government. There is a fairly large set of measures for such a policy. Nevertheless, the scale and complexity of the problems in the fishing industry in our country necessitates a further search for optimal forms of interaction between the state and the organizations of the fishing business. The basis of interaction can be the PPP mechanism — one of the generally recognized ways to solve complex socio-economic problems. The purpose of this article is to develop an approach to the organization of financial management of PPP projects in the field of fisheries. The theoretical basis of the work is the provisions of the methodology of financial planning and project finance management. The article discusses the financial and economic aspects of PPP projects in the fishing industry. A multilevel model for organizing financial planning of such projects is proposed, recommendations are given on its practical application and the selection of tools that serve as its filling. It is concluded that the goal of financial planning of PPP projects in the fishing industry is to ensure long-term sustainable development of enterprises, consistent with the priorities and goals of social development. The scientific novelty of the work done is to systematize the views on PPP finance management and develop on this basis an approach to organizing a financial planning system within the framework of PPP projects taking into account the specifics of the fishing industry. The practical value of the results of this study is determined by the possibility of using them to develop measures of state economic policy in the field of the fishery complex, in particular, in the formation of state and regional target programs, as well as in the implementation of PPP mechanisms in the industry. It seems that the detailed study of financial planning tools and the development of practice-oriented methods that ensure the effectiveness of the PPP financial management system in the fishing industry can become a promising area for further research.

In the United States, the iconic groundfish fishery for Gulf of Maine cod has endured several dramatic reductions in annual catch limits and been federally declared an economic disaster. Using a repeated cross-sectional survey of fishing captains to assess potential social impacts of the fishery failure, we found that psychological distress and social disruption were pervasive throughout New England fishing communities. For instance, our results indicate that 62% of captains self-reported severe or moderate psychological distress 1 y after the crisis began, and these patterns have persisted for 5 y. Using classification tree analyses, we found that low levels of trust in fisheries management was the most powerful predictor of both initial and chronic psychological distress. Distress was most severe among individuals without income diversity and those with dependents in the household. Compared to other aspects of fisheries, measuring and managing for noneconomic social outcomes and human well-being has lagged behind, even though it is a necessary component of mitigating the adverse impacts of fisheries disruptions.

The United Nations calls on the international community to implement an ecosystem approach to fisheries (EAF) that considers the complex interrelationships between fisheries and marine and coastal ecosystems, including social and economic dimensions. However, countries experience significant national challenges for the application of the EAF. In this article, we used public officials’ knowledge to understand advances, gaps, and priorities for the implementation of the EAF in Chile. For this, we relied on the valuable information held by fisheries managers and government officials to support decision-making. In Chile, the EAF was established as a mandatory requirement for fisheries management in 2013. Key positive aspects include the promotion of fishers’ participation in inter-sectorial Management Committees to administrate fisheries and the regulation of bycatch and trawling on seamounts. Likewise, Scientific Committees formal roles in management allow the participation of scientists by setting catch limits for each fishery. However, important gaps were also identified. Officials highlighted serious difficulties to integrate social dimensions in fisheries management, and low effective coordination among the institutions to implement the EAF. We concluded that establishing clear protocols to systematize and generate formal instances to build upon government officials’ knowledge seems a clear and cost effective way to advance in the effective implementation of the EAF.

Overfishing can occur in open access fisheries, where fishermen conduct fishing activities without restrictions. Fisheries management based on biological factors alone (Maximum Sustainable Yield approach) is considered inadequate because it does not consider socio-economic aspects in fisheries management. The study aims to analyze the utilization of small-scale fishery resources in Semarang City and determine its policies to be sustainable. Bioeconomic analysis was used to optimize the utilization of fishery resources. Small-scale fisheries management strategic policies, used analysis of Interpretative Structural Modeling (ISM). The results showed utilization of small scale fishery resources in Semarang City can be achieved with optimal production of anchovy (Stolephorus spp.) 1,477.79 tons/year and optimal effort of 324 units; optimal production of Tembang (Sardinella fimbriata) 235.96 tons/year and optimal effort of 516 units; optimal production of mackerel (Rastrelliger kanagurta) 28.51 tons/year and optimal effort of 479 units; and optimal production of Petek (Leiognathus sp.) 25.54 tons/year and optimal effort of 847 units. In conclusion, the Anchovy (Stolephorus spp.) resources have experienced overfishing since 2007-2008; Mackerel (Rastrelliger kanagurta) resources overfishing occurred from 2009-2015; and Petek (Leiognathus sp.) resources have experienced overfishing since 2014-2016; while Tembang (Sardinella fimbriata) resources have not experienced overfishing because they are not the main target. The key sub-elements of small-scale fisheries management in Semarang City include: a) fishermen; b) Semarang City Fisheries Agency; c) overcapacity; d) decreasing catches; e) environmentally unfriendly arrests; f) ineffective regulation; g) conservation fish resources; h) increasing fishermen's income; i) limitation environmentally unfriendly fishing gear.

Tittle: Sustainability Analysis of Small Scale Fisheries in Tegal District of Central Java (a Fish Approach).The research on sustainability of small scale fisheries in Tegal district, Central Java has been carried out. Fishery sustainability is determined by several interacting factors, such as ecology, technology, social, economic and legal-institution. The objective of this study was to determine the sustainability status of small scale fishery according to ecological, technological, social, economic, and legal-institutional dimensions. The second objective was to identify policy promoting for the capture fisheries sustainability. Sustainability of fishery in the coastal area of Tegal district analyzed quantitatively by Rap fish technique. Fishing gears, such as Jaring Rampus, Bundes and Payang Gemplo weren’t in sustainable status from ecological, economic, technical and legal- institutional standpoints. The study showed that ecological aspect has the lowest score in order to support small scale fishery sustainability in the coastal water of Tegal. Differences in sustainability status are likely due to variations in main characteristic of the fisheries. Several sensitive attributes and recommendations in order to support fisheries sustainability, also identified in this study. This study reconfirms the need to apply comprehensive and integrated bio-technico-socioeconomic aspects in developing fisheries management.

Abstract The slipper lobster Scyllarides delfosi is an important resource captured by fishery fleets of red lobster (Panulirus argus westonii) in northern Brazil. Despite the economic potential of this species, information on its biological and fishery aspects is still nonexistent. This study was conducted using four-year data on slipper lobster (2001 and 2003, 2013 and 2014) to analyse population structure and estimate fecundity and egg size of S. delfosi. A total of 547 slipper lobsters, S. delfosi, were collected. Ovigerous females and individuals of all size classes were captured by the fleet, mostly individuals newly recruited to the adult stock. These lobsters showed a 7-mm decrease in total mean length over a period of 10 years. Fecundity ranged from 24,710 to 190,060 eggs and egg diameter ranged from 0.60 to 0.64 mm. Research on life cycle, reproduction, and growth of S. delfosi is essential to provide support for the sustainable exploitation of this species, which is considered by-catch on the northern Brazilian coast, and as such, has no adequate public policies regarding its management.

Full textAbstract:
Finding an alternative feed source for the replacement of fish oil (FO) and fish meal (FM) produced from whole fish has been an important issue for realizing sustainable aquaculture. In this study, fishery by-products generated in the distribution phase, known as urban fisheries biomass (UFB), were focused on. The quality parameter and nutrient components of FO and FM from UFB were analyzed. Although crude FO produced from UFB showed relatively poor quality properties, the refinement process made an improvement of the quality to make it comparable to commercially available FO. There is no big variation in several samples in fatty acid profiles of FO and amino acid profiles of FM, and they seem to be able to replace FO and FM from whole fish in the diet for cultured fish. The utilization of UFB should be promoted in economic and ecologic aspects; however, in use of the FM, there remains a risk of intra-species recycling that might lead to transmissible spongiform encephalopathy. Furthermore, we must take into consideration the possibility of contamination of fishery products from at-risk species and illegal, unreported, and unregulated (IUU) fisheries due to the lack of regulations in Japan.

This article examines adaptive resource management (ARM) as it has been applied to the US horseshoe crab fishery over the past decade. As a critical yet constructive exercise, I have three goals: to suggest how adaptive management, for all its promise, can still be improved; to add a nuanced case study to the literatures on the quantification of nature and environmental decision-making; and to use the example of ARM to make certain temporal aspects of contemporary natural resource management more salient to science and technology studies scholars—that is, to show the ways in which time matters in environmental science, policy, and the analysis thereof. I draw attention to the time-related aspects of adaptive management by developing the notions of temporal orientation and chronological accountability. Temporal orientation refers to the time-based perspectives and epistemological commitments—that is, past-facing empiricism versus future-oriented modeling—that scientists of different types bring to bear on environmental problems. Chronological accountability refers to the missing link in adaptive forms of environmental governance: firm time lines and commitments to reflexively revisit management decisions. The time-related aspects of natural resource management deserve greater attention among both environmental managers and analysts of environmental policy.

Full textAbstract:
Abstract A development of the ecological risk screening (ERS) technique, scale intensity and consequence analysis (SICA), is described and application to the varied fisheries and ecosystem off the southwest of England on behalf of an industry steering group (SG) is summarized. The purpose was to prioritize ecological risks systematically and consistently in relation to policy goals agreed by the SG. Scientists listed and advised on ecosystem components, their units (individual species, stocks, habitats, or communities) and attributes, as well as agents of change in the SW, their activities, and generalized effects relevant to the policy goals. A working group (WG) of fishers, fishery observers, technical advisors, and marine scientists paired each unit with the activity thought most likely to impact the most sensitive policy goal, then scored risk according to defined rules spatially, temporally, and as intensity and duration of effects. The geometric mean of the four scores, slightly adjusted for unscored factors if necessary, was the relative impact score (RIS). With this standardized method, the main aspects of risk were considered separately and independently, thereby assisting objective prioritization. Nineteen unit–activity pairs were listed as priority risks (RIS >3) in the SW region during a 2-d meeting that fully exploited the wide range of information and experience available at the WG. Socio-economics was not considered. The ERS for the SW was designed to be compatible with other similar ERSs that might be carried out for neighbouring marine regions. ERS can minimize extra monitoring needed for ecosystem management and, in principle, collaborating non-fishery agents of change could be included. By engaging all stakeholders in the setting of initial priorities for action and by assembling all available sources of information, ERS offers a useful starting point for holistic ecosystem management.

Full textAbstract:
Since 1979, southern hake (Merluccius australis) has been exploited in Chile from the Bio Bio to the Magallanes regions, between the parallels 41°28.6'S and 57°S. There is evidence of a constant fishing effort and a sustained reduction of the fish population, consistent with a progressive decrease in total annual catches. Management strategies based on the maximum sustainable yield (MSY) and quota assignment/ distribution criteria have not been able to sustain acceptable biomass levels. A non-linear optimization model with two objective functions was proposed to determine an optimal total catch quota for more sustainable exploitation of this fishery. The first function maximizes the total catch over time in response to an optimal assignment of fishing mortality rates per fleet; the second function maximizes the total economic benefit associated with the total catch. The dynamics of the fish population were represented with the equations of a predictive age-structured model. Decision variables were fishing mortality rates and annual catch quotas per fleet, subject to constraints that guarantee a minimum level of biomass escape over a long-term period. The input parameters were obtained from the last stock evaluation report carried out by the Instituto de Fomento Pesquero (IFOP) of Chile. The historical background data of the fishery and the regulatory framework were relevant aspects of the methodology. Five scenarios were evaluated with the two objective functions, including a base scenario, which considered the referential mortality rate as input data as the average mortality rate per fleet from 2007 to 2012. Total economic benefits fluctuate between 102 and USD 442 million for total catches in the range of 108 to 421 thousand tons, which were obtained from maximizing the economic and biological objective functions. Economic benefit/catch ratios were reduced for scenarios with higher constraints on catch limits, and they were more efficient from a biological point of view. Situations with lighter constraints showed in general higher economic benefits and better performance ratios than those with stronger restrictions. The use of optimization models may provide a useful tool to evaluate the effect of regulations for adequate conservation and economical utilization of a limited resource.

<p>ABSTRACT<br /><br />Tuna is an important fish commodity in Southeast Sulawesi. It valued as an export and interisland trade product as well as an important component of local fish consumption for coastal community around Southeast Sulawesi Waters (PSST). Indonesian fisheries management is currently adopting the concept of ecosystem approach to fisheries management (EAFM). EAFM implementation in Indonesia has continued by indicators establishment to assess the sustainability performance of fisheries. Catch per unit effort standard (Standard CPUE) and juvenile composition were implemented as indicators to assess resource sustainability. Data limitations are one of the issues in fisheries management at this time, however, management efforts remain to be implemented by utilizing the best available data. This study aimed to derived recent ten years coverage of standard CPUE and it trends as well as juvenile proportion in tuna fishery based on statistical data and field observation. Assessment results show that Standard CPUE in 2014 was 0,31 tons per trip and tends to increase in year coverage, while juvenile composition was 48,6%. Based on these results, the tuna fishery in Southeast Sulawesi is still sustainable. However, there is a need to have further control and monitoring, especially on a fishery that caught tuna under Lm. Management measure has to be selected carefully in line with social economic aspects of tuna fishery in this area.<br /><br />Keywords: EAFM, juvenile proportion, Standard CPUE, tuna</p><p>-------<br /><br />ABSTRAK<br /><br />Tuna merupakan komoditas perikanan penting di Sulawesi Tenggara baik sebagai produk ekspor, perdagangan antar pulau maupun pemenuhan kebutuhan lokal bagi masyarakat pesisir di perairan bagian selatan Sulawesi Tenggara (PSST). Untuk mempertahankan keberlanjutan perikanan tuna di daerah ini maka perlu adanya suatu upaya pengelolaan komprehensif yaitu pengelolaan perikanan dengan pendekatan ekosistem atau Ecosystem approach to Fisheries Management (EAFM). Implementasi EAFM di Indonesia terus dikembangkan dengan tersusunnya indikator penilaian kinerja pengelolaan. Tangkapan per Unit Upaya atau Catch per Unit Effort (CPUE) dan komposisi yuwana merupakan bagian dari indikator EAFM Indonesia khususnya dalam domain sumberdaya. Penelitian ini bertujuan untuk memperoleh nilai CPUE baku dan kecenderungannya selama sepuluh tahun terakhir, dan proporsi yuwana berdasarkan data statistik perikanan yang diintegrasikan dengan data yang diperoleh melalui pengamatan, wawancara dan pengisian kuesioner dengan pemangku kepentingan terkait. Hasil penilaian menunjukkan bahwa CPUE baku tahun 2014 adalah 0,31 ton/trip dengan kecenderungan meningkat, sedangkan komposisi yuwana adalah 48,6%. Berdasarkan nilai CPUE baku dan proporsi yuwana, maka kinerja perikanan tuna Sulawesi Tenggara masih dinilai baik. Perlu adanya upaya pengendalian dan pemantauan lebih lanjut terutama pada perikanan yang menangkap yuwana tuna. Namun demikian, pemilihan tindakan pengelolaan harus dilakukan secara hati-hati dengan memperhatikan pemenuhan kebutuhan sosial ekonomi lainnya dari perikanan tuna di daerah ini.<br /><br />Kata kunci: EAFM, proporsi yuwana, CPUE baku, tuna</p>

Metode survei penilaian cepat (rapid appraisal survey) dan review literatur digunakan dalam kajian ini; sedangkan metode analisis deskriptif tabulatif dan content analysis digunakan untuk membantu pengambilan kesimpulan. Hasil kajian menunjukkan bahwa ikan bilih yang ditebarkan ke Danau Toba 2.840 ekor dengan ukuran panjang berkisar antara4,1-5,7 cm dan bobot 0,9-1,5 g pada tahun 2003 telah mampu memberikan dampak positif secara ekonomi dan sosial bagi masyarakat sekitar Danau Toba. Penggunaan alat tangkap yang kurang ataupun tidak terkontrol telah memberikan indikasi penurunan jumlah dan kualitas stok ikan bilih; sehingga implementasi opsi pengelolaan yang meliputi pengembangan kawasan konservasi dan pengaturan serta pengendalian penggunaan alat tangkap bagan untuk menjamin keberlanjutan perikanan ikan bilih perlu segera diterapkan oleh pihak pengelola.Fishery management is essentially a control of fishing and fishing effort through various management options implemented by a management authority. Studies on policies and strategies for fishery management in the Lake Toba water body post introducing or stocking of bilih fish (Mystacoleucus padangensis Bleeker)aimed at providing a sort of guidelines for management practice in order to ensure sustainability of such the fishery. Rapid appraisal survey method and literature review were used in this study. Analysis of the study used a descriptive method compounded by cross tabulated data techniques and a content anaysis method. Results show that introducing of bilih fish in the Toba Lake amounted of 2,840 piece with body length of 4.1-5.7 cm and body weight of 0.9-1.5 g in 2003 has been able to provide a positive impact to social and economic aspects of the society surrounding the Lake Toba. However, the use of uncontrolled fishing and fishing effort was led to indication of decreasing quantitatively and qualitatively such of the fish stock; therefore, implementation of management options of developing a protected or conserved area and controlled the use of bagan fishing gear has to be imposed by management authority.

Fisheries management has been traditionally governed to maximize economic benefit with little concern on its ecological impacts. Food and Agriculture Organization with its Code of Conduct for Responsible Fisheries has played an important role to a fundamental change in the new paradigm of fisheries management, which include ecosystem aspect. The Food and Agriculture Organization has mandated that every country in the world should use this approach. Weh Island is located in AcehProvince that has good coral reef condition and rich in reef fishes, therefore reef fishery is prominent. The objectives of this study are (1) to study the ecological status of reef fish, and (2) to formulate the priority areas as candidates of marine protected areas in Weh Island. Fish catch survey, underwater visual census, and focus group discussion were conducted to collect data. Data analysis used fish biomass, financial analysis, linear goal programming, and marxan analysis. Results of this study successfully identified eight fishing gears operated in Weh Island in artisanal reef fisheries. These fishing gears are gillnet, bottom gillnet, handline, muroami, trolline, speargun, longline, and purseseine. There were 84 species identified as high economic value species and were modelled in this study. Gillnet and bottom gillnet were identified as optimum fishing gears. I.e. Meulee, Anoi Itam, Iboih, Jaboi, and Klah Island were identified as priority areas.

Abstract Managers of recreational fisheries make assumptions about what anglers value, often emphasizing factors directly related to catch. Evaluations that include both catch and non-catch aspects of recreational fishing, as well as the trade-offs between attributes that are trip-based and those that measure opportunity over a season, are rarely be incorporated into management objectives and the design of management frameworks. A study of two marine recreational fisheries in the United States, Pacific halibut in central Oregon and red snapper in northeast Florida, comprised local interviews and a limited survey of recreational anglers to evaluate the relative importance of catch rates, season length, and the uncertainty around early closures. National meeting reports, interviews, and stated-preference survey results suggested that angling opportunity in the form of longer seasons may be more important to anglers than either catch rates or the uncertainty that results from mid-season changes to fishery closure dates. Results suggest that researchers evaluating economic benefits to anglers should consider including opportunity attributes directly in angler surveys. Issues associated with limited sample sizes and a lack of intermediate attribute values limit the use of this study for direct regulatory guidance, but it instead offers a potential methodology to be applied in future analyse.

Full textAbstract:
Kajian ini menganalisis aspek sosial ekonomi perikanan cucut dan ikan pari di Indonesia, terkait dengan relevansi aspek tersebut dalam rencana aksi nasional (national plan of action, NPOA) untuk sumberdaya elasmobranchii. Pengambilan data dilakukan pada periode Agustus 2004 - November 2005 di lokasi-lokasi pendaratan utama, yaitu Tanjung Luar (NTB), Kedonganan (Bali), Sungai Kakap (Kalbar), Sungai Liat (Bangka Belitung), Muara Angke (Jakarta) dan Batang (Jateng) serta beberapa lokasi pendukung. Analisis deskriptif tabulatif yang dilakukan terhadap data-data tersebut, menunjukkan bahwa produksi cucut dan ikan pari memberikan kontribusi signifikan terhadap pendapatan nelayan, baik yang menangkap cucut sebagai target utama maupun hasil sampingan. Di lokasi dimana cucut atau pari merupakan target utama, yaitu Tanjung Luar, Sungai Liat, dan Sungai Kakap, setiap ABK memperoleh pendapatan berturut-turut sebesar Rp 20,8 juta, Rp 24,1 juta dan Rp 8,5 juta per tahun. Nilai ini sebanding dengan tambahan pendapatan yang diperoleh ABK di lokasi dimana cucut atau pari merupakan hasil samping (Kedonganan dan Batang), yakni sebesar masing-masing Rp 27,7 juta dan Rp 22,4 juta pertahun. Nilai ekonomi perikanan cucut dan pari juga terkait dengan nilai tambah dari aktivitas pengolah, pengrajin, tukang potong, kuli angkut, dsb. Hasil analisis selanjutnya menunjukkan adanya peluang untuk menyusun sebuah NPOA yang selaras dengan kepentingan ekonomi nelayan, misalnya dengan meningkatkan nilai tambah hasil tangkapan sehingga penurunan volume tangkapan tidak harus menyebabkan turunnya pendapatan. Sejauh ini, nilai tambah perikanan cucut dan pari bervariasi; misalnya, 3,5 % untuk cucut dan 23% untuk pari di Kedonganan, jauh dibawah nilai tambah cucut di Sungai Kakap (290%) dan pari di Batang (75%). Implikasi dari hasil ini adalah pentingnya upaya penciptaan nilai tambah disamping perlunya kajian lanjutan untuk merumuskan mekanisme teknis untuk mengurangi volume produksi sesuai dengan kondisi lapang. Tittle: Economic Value of the Shark and Ray Fishery and their Management ImplicationThis study analyses the socio-economic aspects of Indonesian shark and ray fisheries as related to the relevance of these aspects in a National Plan of Action (NPOA) for elasmobranchii resources. Data were collected in the period of August 2004 to November 2005 in primary shark and ray landing places, namely Tanjung Luar (NTB), Kedonganan (Bali), Sungai Kakap (Kalbar), Sungai Liat (Bangka Belitung), Muara Angke (Jakarta) and Batang (Jateng) and a number of complementary locations. A tabulated-descriptive analysis shows that shark and ray production contributes significantly to the income of the fishers, both who produce shark and ray as main targets and by-catches. In locations where shark or ray is the main target, namely Tanjung Luar, Sungai Liat, dan Sungai Kakap, an individual crew fisher would, respectively, earn as much as Rp 20.8 million, Rp 24.1 million and Rp 8.5 million annually. These values by and large match with the annual additional income earned by every crew producing shark or ray as by-catch in Kedonganan and Batang, who would receive Rp 27.7 million and Rp 22.4 million. A further analysis shows an opportunity to formulate an NPOA which is parallel with the fishers' economic interests, namely through the improvement of added values in such a way that reduction in catch will not necessarily cause decreases in income. So far, the value added for fisheries commodities is various; for example, 3.5 % for shark and 23% for ray in Kedonganan, as compared to shark value added in Sungai Kakap (290%) and ray value added in Batang (75%). The implication of this research is that efforts directed to the creation of value added and the formulation of technical mechanism to reduce production become essential in developing a workable NPOA.

Full textAbstract:
The paper provides an outline of the financial aspects of the foreign direct investment decision process and an understanding of how this can help attract funds for Australian petroleum exploration and development.Proposals to foreign investors are seen to require specific personal presentations. The investors' view of risk is discussed under the headings of political, economic, and environmental, and the major risk factors that require understanding are shown to be country risk; exchange rate risk—rate forecasting and exposure management; and international taxation.The techniques in assessing country risk are reviewed, and the methodology of international banks assessed. The Go/No-Go, Premium for Risk, Range of Estimates, and Risk Analysis techniques are described.In considering the forecasting of exchange rate movements it is recognized that, while there is no adequate forecasting measure, the major variables of comparative prices, interest rates, and comparative money supply require attention. The mechanistic tools of purchasing parity theory and the Fisher effect formula on interest are therefore outlined.The management strategy in the management of exchange rate movement exposure is seen to require a determination of economic exposure, the observance of basic rules in currency grouping, and market operation guidelines. A management guide is set down for reference.A reference to international taxation indicates the need of the tax planner to consider comparative taxation domicile of investment, and corporate structure.The basic taxation principles that apply are seen as the necessity to plan in after-tax terms; the importance of determining the nature and sources of taxes; and the requirement of a full knowledge of relevant double taxation agreements and local tax administration regulations.The role of the Australian petroleum industry in attracting foreign investment is seen as promoting the provision of data, increased opportunities to invest, risk reduction through tax effective opportunities, and assisting in proposal presentations.The need for earlier release of exploration data is expressed, as is the development of comprehensive updated data packages—which would include basin reviews—for use by industry. A zoning approach to areal permit size that provides for a reduction in permit size with exploration maturity is seen as an approach to increasing investment opportunities. Finally, APEA is encouraged to take a leading role in encouraging foreign investment through direct participation in presentations.

Abstract This study aimed to describe the characteristics and cultivation conditions of Thunnus albacares in Pelabuhan Perikanan Pantai (PPP, shore-port fisheries) of Labuhan Lombok, East Lombok. Data was collected by a simple random sample using a questionnaire for 30 fishing boats. Primary data was collected by interview with respondents and field observation, while secondary data was obtained from records of PPP in Labuhan Lombok, BPS and DKP, East Lombok. Results showed that East Lombok has a high potential for T. albacares cultivation as well as eco-friendly fishery cultivation; this is practiced by local fishermen who commonly use traditional boats sized 4-7 GT complete with fishing utilities, including handline rods and trolling rods. From a biological aspect, there was open access to T. albaceros in 2006, followed by biological overfishing in 2007, and economic overfishing in 2005, 2008, 2009, 2010 and 2011. The maximum sustainable yield (MSY) reached 922,518.18 kg per year (MSY level 3,313 per year). The resource optimization of T. albaceros reached the peak of maximum economic yield (MEY) valued at IDR 24,693,982,361, with fish haul efforts from 2,063 annual trips yielding 791,270.90 kg of tuna per year.

Full textAbstract:
Freshwater fishing is an important socioeconomic aspect of the communities in the Cagayan de Oro River (CDOR), Philippines. The fishery sector in CDOR has the elements that are generally characteristic of artisanal or small-scale fisheries. Before this study, very little was known of the scope and magnitude of artisanal level fishing activities within the CDOR. It has remained undocumented by Local Government Units (LGUs) as it does not contribute directly to the economy in terms of measurable cash flow. However, a number of fishes in the river have higher commercial value compared to marine fisheries in the nearby Macajalar Bay. This study is an attempt to examine the conditions of the CDOR fisheries and to quantify its economic contributions. The economic contribution is measured in terms of the market value of captured aquatic resources. In order to establish the behavior and trends in the fisheries of the different communities, the study area was divided into three sub-zones. Data in this study were collected through interviews of identified fishermen in the different sub-zones. Majority of the fishermen venture into other menial jobs due to proximity to the urban center. Many of them have subsidiary occupations which serve the dual purpose of alternative income and job opportunities and food source because fishing is seasonal. The peak fishing season usually spans two to four months. Comparatively, the earnings derived by the Cagayan de Oro River fishermen are relatively in almost the same range as the marine fishermen in the different parts of the country.

Full textAbstract:
Woodside has been managing seismic acquisition and drilling operations as part of a gas exploration program in the offshore Otway Basin in southwest Victoria since July 1999. There are a number of sensitive and complex environmental and multiple-use issues facing companies undertaking exploration activities in these waters, including a seasonal aggregation of feeding blue whales, winter calving and breeding habitat for southern right whales and a productive rock lobster fishery. Recent changes to the legislative regime for environmental approvals of petroleum activities in Commonwealth waters has introduced further complications for operators in this area. Consequently, a key aspect of this exploration program has been the pro-active management of environmental and stakeholder issues.A comprehensive management strategy addressing these issues was developed for seismic acquisition and drilling operations, with the key objectives of ensuring regulatory compliance and facilitating a process where all stakeholders were fully informed about proposed activities. This process focussed on informing stakeholders of the potential impacts of seismic acquisition and drilling, and how Woodside intended to manage those impacts. This approach was driven by a desire for continuous improvement of performance, over and above compliance with all regulatory requirements. It also recognises the legitimacy of stakeholder risk through social, environmental and political values, and has had environmental and economic benefits for the project.Environmental benefits included early identification and assessment of potential environmental impacts resulting from the different phases of exploration, development of management strategies to control and mitigate these potential impacts, and improved environmental awareness across the project team, joint venture partners and external stakeholders. Prevention of delay or denial of regulatory approvals for exploration activities had significant economic benefits to Woodside and the joint venture partners. The development and implementation of a stakeholder involvement process, involving explorers, external affairs and environmental advisers, was an innovative approach that has application across other Woodside activities and the industry generally, particularly for projects in locations with a high level of environmental sensitivity, multiple-use and stakeholder concern.

The study adopted descriptive survey design and draw on a quantitative inquiry. The sample size, determined by Fishers method, were 245 patients and 10 medical officers (medical superintendent, oncologists and nurses) drawn from the Nakuru County Teaching and referral Hospital. The research instruments employed were the questionnaire and interview schedules. Before the actual data collection, piloting of questionnaires and the interview schedule was done in Moi Teaching and Referral Hospital in Uasin Gishu County. Data analysis followed both parametric and non-parametric approaches. Data was presented using graphs, tables and scatter diagrams. The findings of the study suggest a strong association of cancer with loss of income (????16, 0.01 = 40.101) and a significant increase in medical expenditure (????12, 0.01 = 66.789). Similarly, it was shown that cancer patients were impacted both socially and economically by cancer type (????12, 0.033 = 22.46) and duration of treatment. The results from the study will contribute immensely to the development of new strategies to improve patients’ economic status in the management of cancer within Nakuru county and Kenya in general.

Abstract. Hypoxia has become a world-wide phenomenon in the global coastal ocean and causes a deterioration of the structure and function of ecosystems. Based on the collective contributions of members of SCOR Working Group #128, the present study provides an overview of the major aspects of coastal hypoxia in different biogeochemical provinces, including estuaries, coastal waters, upwelling areas, fjords and semi-enclosed basins, with various external forcings, ecosystem responses, feedbacks and potential impact on the sustainability of the fishery and economics. The obvious external forcings include freshwater runoff and other factors contributing to stratification, organic matter and nutrient loadings, as well as exchange between coastal and open ocean water masses. Their different interactions set up mechanisms that drive the system towards hypoxia. Coastal systems also vary in their relative susceptibility to hypoxia depending on their physical and geographic settings. It is understood that coastal hypoxia has a profound impact on the sustainability of ecosystems, which can be seen, for example, by the change in the food-web structure and system function; other influences include compression and loss of habitat, as well as changes in organism life cycles and reproduction. In most cases, the ecosystem responds to the low dissolved oxygen in non-linear ways with pronounced feedbacks to other compartments of the Earth System, including those that affect human society. Our knowledge and previous experiences illustrate that there is a need to develop new observational tools and models to support integrated research of biogeochemical dynamics and ecosystem behavior that will improve confidence in remediation management strategies for coastal hypoxia.

The present study was concerned to assess the present status of biodiversity in the Bhairab river, Jessore with its conservation measures. The study was based on primary observations, questionnaire interviews with 50 fishers, focus group discussions with river bank community members and cross-check interviews with key informants. The study was conducted for a period four months from May to August, 2016. The objective of the study was to assess the fish biodiversity in the Bhairab river, understand the existing fishing practices of the river and to identify proper management strategies for the conservation of fish biodiversity. Results of the study revealed that three kinds of fishers were engaged in the Bhairab river namely, professional fishers; seasonal fishers and subsistence fishers. Seven types of fishing gears like seine net, gill net, cast net, push net, lift net, trap and hook and line were operated to fish by the fishers during the survey. A total of 39 species of fish were identified in the catches of the Bhairab River. There are degraded ecosystems and declining biodiversity have found during the study. According to survey, fishing pressure and over fishing were responsible for almost 38% loss and pollution and siltation caused about 27% loss of ecosystem. Around 21% and 14% loss of ecosystem were caused by urbanization and human encroachment, and the recreational activities respectively. These have been created a great impact on river ecology. As a result, the water quality is deteriorating day by day and the availability of fish species and other aquatic biodiversity is decreasing gradually. During the survey, 20 species was found at a risk of being endangered. From the survey, it was found that the overexploitation of fish was responsible for the 40% losses of biodiversity in the Bhairab River and water pollution caused 35% loss of biodiversity. Henceforth, river course change and habitat degradation resulted in 15% and 10% loss of biodiversity of the river respectively. This study was identified possible ways to achieve a rich fish biodiversity in the Bhairab River with social, economic and environmental aspects. The specific recommendations are included community based fisheries management, establishment of sanctuary, control of pollution, maintenance of fishing gears and the implementation of fish act for conservation of fish biodiversity of the Bhairab River.Asian J.
