Conservation and management of transboundary fisheries must account for diverse national interests while adopting compromises necessary to develop and implement robust conservation and management measures. The United Nations Fish Stocks Agreement requires states to ensure that conservation and management measures for straddling and highly migratory fisheries do not transfer a disproportionate burden of conservation action onto developing states. However, fulfilling this obligation in transboundary fisheries is undermined by the lack of agreed transparent frameworks for assessing the impact of alternative conservation and management measures, and distributive decision making processes for adopting measures that meet scientific and equity obligations. A new informal and multi-disciplinary research partnership, the Fisheries Equity Research Network, has been established to encourage international research into the equitable distribution of conservation limits in trans-boundary oceanic fisheries. The Fisheries Equity Research Network will research transparent and equitable rules and frameworks for assessing and distributing conservation burdens in transboundary fisheries. 相似文献

Policy efforts to reduce fisheries impact have often created micro-management. Detailed regulations are restricting the fishing industry, and are also acknowledged to limit the progress towards sustainable management. Industry representatives, political bodies and scientists have therefore argued for more simplicity and transparency. Here, fisheries management is quantified in terms of trends in regulations for different Swedish fisheries in the Baltic Sea during the period 1995–2009. The results suggest that many fisheries are suffering from increased micro-management, but interestingly some fisheries showing a different trend. 相似文献

While the economic and environmental benefits of fisheries management are well accepted, the costs of effective management in low value fisheries, including the research necessary to underpin such management, may be considerable relative to the total economic benefits they may generate. Co-management is often seen as a panacea in low value fisheries. Increasing fisher participation increases legitimacy of management decision in the absence of detailed scientific input. However, where only a small number of operators exist, the potential benefits of co-management are negated by the high transaction cost to the individual fishers engaging in the management process. From an economic perspective, sole ownership has been identified as the management structure which can best achieve biological and economic sustainability. Moving low value fisheries with a small number of participants to a corporate-cooperative management model may come close to achieving these sole ownership benefits, with lower transaction costs. In this paper we look at the applicability of different management models with industry involvement to low value fisheries with a small number of participants. We provide an illustration as to how a fishery could be transitioned to a corporate-cooperative management model that captures the key benefits of sole management at a low cost and is consistent with societal objectives. 相似文献

This study examined the use of Individual Transferable Quotas (ITQs) to effectively manage fishing impacts on all ecosystem components, as required under Ecosystem Based Fisheries Management (EBFM) principles. A consequence of changing from input controls to output-based (catch) management is that the control of the regulating authority tends to be reduced, which may affect the outcomes for ecosystem management. This study reviewed the use of input controls across six fishing methods in 18 ITQ fisheries, which have been independently accredited as ecologically sustainable by the Marine Stewardship Council (12 fisheries) or under Australian environmental legislation for Wildlife Trade Operation (six fisheries). Input controls were retained across a range of ITQ fisheries, with non-selective fisheries such as trawl, gillnet and line employing more input controls than selective fisheries such as purse-seine, pot/trap and dredge. Further case-studies confirmed the widespread and recent use of input controls (spatial and temporal closures) with the aim of managing ecosystem impacts of fishing. The retention of input controls, particularly closures affects the security (quality of title) characteristic of the fishing use right and the theoretical ability of fishers to manage their right for their future benefit. The security characteristic is weakened by closures through loss of access, which undermines industry trust and incentive for long-term decision making. By reducing the security of ITQs, individual fisher incentives and behaviour may separate from societal objectives for sustainability, which was one of the foremost reasons for introducing ITQ management. 相似文献

Expansion and development of the fisheries sector was the driving force behind Iceland’s economic transformation during the 20th century. However, the role of fisheries in national and regional economies is neither well documented nor understood. National accounts do not fully reflect the significant part played by the fisheries as they do not take into consideration the various ways economic activity in the fisheries sector affects other branches of the economy. The fisheries sector, which includes fishing and fish processing, has been established as a base industry within the Icelandic economy. Using data collected during 2010 and 2011 and cluster analysis techniques, this paper seeks to establish the economic importance of the fishing industry in Iceland. As a base industry, this paper finds that a wide range of companies have gradually developed to service the sector and through these interlinkages, the fisheries sector and its related operations can be viewed as an industry cluster. 相似文献

Fisheries co-management is claimed to increase the legitimacy of regulations by allocating management authority to selected users. In this article, experiences from a case study in the inshore fisheries of Ireland involving the establishment of a fisheries co-management system are used to discuss the specific problem of finding an unit to whom regulatory authority may be delegated. Here, the fishers who will benefit from the co-management scheme will also carry the costs, and it is argued that establishment of formal economic liability between those granted management privileges and those excluded can optimise the legitimacy of management authority in fisheries co-management systems. 相似文献

The European Common Fisheries Policy (CFP) has failed to deliver on social, economic and ecological goals. This failure is in part the result of a number of social–ecological feedback mechanisms. The policy is currently undergoing reform, with unknown practical outcomes. Here, relatively successful fisheries policies outside the European Union are reviewed. Through interviews and workshops with scientists, managers and other stakeholders, complemented with literature reviews, practices that can create incentives for long-term sustainability are investigated. The focus is on how the provision of clear and trusted scientific evidence can stimulate defensible decisions, in turn creating incentives for compliance, leading to positive social–ecological outcomes. Despite differences between Europe and the investigated case studies, the prospects of an increased regionalization within the European CFP provides the best starting point for implementing best practice identified in this study. 相似文献

Despite their apparent economic benefits to harvesters, individual fishing quotas (IFQs) have only been adopted in three US fisheries: Mid-Atlantic surf clam and ocean quahog; South Atlantic wreckfish; and, North Pacific halibut and sablefish. During the 1996 reauthorization of the Magnuson-Stevens Fishery Conservation and Management Act, Congress temporarily blocked implementation of additional IFQ programs in US fisheries. In this paper, we argue that because of the emergence of an alternative, the cooperative, it is unlikely that new IFQs will be adopted in federally managed US fisheries. From an economic perspective, cooperatives offer the advantage of eliminating production externalities that may remain under an IFQ program with relatively large owner classes. More significantly, development of IFQ programs appears to be increasingly overwhelmed by the proliferation of both equity concerns and seemingly interminable rent-seeking behavior — both issues that can effectively block adoption of IFQs. Ironically (and paradoxically?), by reducing the scope of the equity issues acknowledged, the cooperative alternative narrows the pool of claimants and modifies the behavior of the remainder, making implementation more likely. A further irony exists in that IFQs are widely thought to be best designed at the local/regional level while part of the appeal of the cooperative model is that it appears to shortcut the often protracted nature of the local/regional political process by relying on direct intervention from Washington, DC, in the form of actions by Congress or the Justice Department. 相似文献

This paper chronicles and analyzes the political dispute that resulted when Russia gave South Korea permission to fish for saury in the Kurile area disputed by Russia and Japan. The dispute became a three-sided diplomatic wrangle and threatened to disrupt relations between the countries involved. In the resolution of the dispute, each side gained and lost both politically and economically. Given the difficult political relations in Northeast Asia, fisheries policy makers should consider the international political ramifications of their decisions. 相似文献

There are two types of interactions between seals and commercial fisheries in South Africa: biological (potential competition for shared resources between the two "predators") and operational (conflicts during fishing operations). Using data for the 1980s, a comparison is made of relative consumption by different predators in South African waters. Seals and fisheries are not the major consumers in the system, but they do take comparable amounts. This has resulted in calls for a reduction in the seal population, but to date, no studies have shown that reducing seal predation of commercial species will make more fish available for the fisheries. Most fisheries are subject to some form of operational interaction with seals. These interactions include consumption of catches (operational consumption), disturbance of fishing operations (operational disturbance) and damage to fishing gear (operational gear damage); they vary in degree of severity, both seasonally and regionally. Estimates of the consumption by seals from fishing operations in South Africa show it to be a minimal percentage of fishery catches and a small proportion of the total predation by seals. Preliminary calculations of overall economic losses resulting from seal interference show this to be small in comparison with the wholesale value of the catches. Seals die as a result of fishing operations, and estimates of the potential mortality through entanglement, drowning and deliberate killing indicate this mortality to be of a magnitude that should be monitored. 相似文献

The new protocol signed in July 2012 by the European Union and Mauritania under the existing Fisheries Partnership Agreement did not produce the expected results. The main component of this protocol consisted of the access rights for 300,000 t/yr of small pelagics. During the first five months after the signature of the protocol, no EU pelagic trawlers used the opportunities created by the protocol. Only after the formal approval of the protocol by the European Council in December 2013, some eastern EU member states started sending their pelagic trawlers back to Mauritania. This resulted in a utilisation of the protocol of 54% for the whole of 2013. Although the EU repeatedly stated that the €70 million/yr paid under the protocol provided good value for money, this assertion was hard to maintain considering the limited utilisation of the agreement. The paper analyses why the EU concluded an agreement with Mauritania that was not wanted by their industry and that was therefore only partially used in the end. It describes the decision making process inside the EU; the different parties involved and their different objectives. It is concluded that the EU decision making process suffers from a lack of transparency and that the combination of a business agreement with development aid resulted in an agreement which did not attain either of the stated objectives. It is proposed that in future the two aspects are clearly separated, and that the development component is extended to other countries in West Africa, including those that have no fish to sell to the EU. 相似文献

A review of indicators for an ecosystem approach to fisheries management is presented, focusing on multispecies fisheries and limited resources for assessments and implementation, as often is the case in developing countries. Emphasizing the need to link indicators to management objectives, indicators from the literature are grouped into four categories, relating to the immediate fisheries resource base (single-species and multispecies indicators) and the wider ecosystem (habitat structure and ecosystem functioning). The usefulness of these indicators is assessed along three dimensions of acceptability among stakeholders, observability, and relation to fisheries management using a traffic light approach. The top ranking indicators are highlighted as a generally good start for any particular fishery management case. It is, however, argued that, even with similar management objectives, indicators need to be specific to both ecosystems and the institutional set-up if they are to be effective for management, and that indicators may consequently differ considerably between individual management applications. 相似文献

China(herein referred as China’s mainland,and excluding Hong Kong,Macao and Taiwan)ranks as the world’s leading fishing nation,with approximately 11.1 million tons of domestic marine catch acquired in 2017.Marine fisheries resources in China are mainly exploited by its 11 coastal provinces and municipalities,and the development of fishing industry varies among them.However,few studies have examined the exploitation history of the 11 coastal provinces and municipalities.In this paper,we systematically quantified the exploitation history of marine fishery resources in China and then measured the vulnerability of the 11 coastal provinces and municipalities of China to a reduction in marine catches.Our analysis suggested that Chinese marine fisheries experienced rapid growth from the mid-1980 s to the end of the 20 th century,and this rapid increase in marine catches were mainly promoted by increased fishing effort.The total primary production required level amounted to approximately 80%of the average primary productivity in 2017,and Zhejiang,Fujian,Shandong,Hainan and Guangdong provinces were the main fishing provinces in China.By assessing three dimensions of vulnerability(exposure,sensitivity and adaptive capacity)to the impacts of a reduction in marine catches in the 11 coastal provinces and municipalities,we found that Hainan,Guangxi,Zhejiang and Fujian provinces had high or very high vulnerability,while the municipalities of Shanghai and Tianjin had low vulnerability.Identifying suitable adaptation policies and management plans based on the differences in vulnerability among coastal provinces is important in sustainable fisheries management. 相似文献

Fisheries management has long been characterised by strong user-group involvement, created to enhance the legitimacy and proficiency of decisions. Due to perennial problems of overfishing and resource depletion, the privileged position of users are increasingly being challenged, and there have been calls for more inclusive and democratic institutions. Fish, it is argued, is a public resource and should be managed through institutional arrangements that take the public interest into account. Taking the demands for more inclusive and transparent management institutions as our starting point, the article addresses some of the issues emanating from a stakeholder approach to fisheries management. Against the backdrop of stakeholder theory, as it has been developed in the literature on business management, we attempt to identify—and classify—those with a legitimate stake in the fisheries. We also address some of the problems and complexities of stakeholder management, and conclude with a discussion of some of the central issues and challenges pertaining to the creation of more inclusive and transparent institutions in fisheries management. 相似文献

In the Pacific, coastal communities have compensated for chronically low capacity of governments to manage fisheries by implementing local regulations in their marine tenure areas. In order to investigate the performance of community-based fisheries management (CBFM) in Vanuatu, trajectories and factors of change in CBFM systems since the 1990s were analysed. Focal group interviews were conducted in seven villages on Efaté island in 2011 and supplemented by a review of supporting literature. Results reveal the increasing and excessive reliance of CBFM systems on external agencies that promoted overly complex management plans. Examination of trends in CBFM systems shows that community and national fishing rules that were highly acceptable by local societies were more likely to be enforced in the long run. In particular, the establishment of marine reserves was the most widespread and best enforced community rule for the purposes of conservation, ecotourism, and/or fisheries. Overall, the results challenge the current effectiveness of CBFM in achieving sustainability of reef fisheries in Vanuatu, and highlight the over-reliance on small marine reserves as a management tool. Community initiatives must be strengthened by new specific national regulations governing subsistence and commercial reef fisheries as part of a multi-scale co-management approach. 相似文献
