The ecosystem approach for fisheries management is a widely accepted concept and various international instruments require its application. However, there are various interpretations of the ecosystem approach and its application almost always brings about confrontations and resistance among managers, proponents, and stakeholders. This paper categorizes the ecosystem approach into four distinguishable types: bycatch mitigation, multi-species management, protection of vulnerable ecosystems, and integrated approach. Furthermore, the lack of identification and understanding of specific management goals is hampering the application of the ecosystem approach. Unless the stakeholders understand and accept the goals, the ecosystem approach will not succeed. 相似文献

A multi-objective programming model has been applied to investigate conflicting goals of the Norwegian cod fisheries. The goals included in this article are economic rent and employment. Fisheries managers are confronted with the problem of how best to allocate the total allowable catch (TAC) of cod among eight vessel groups. Compromise solutions taking into account both objectives by giving them equal weights in the multi-objective programming model are calculated and discussed. This article is an extension of an earlier article in which the trade-off analysis was performed using data only for North Norway and one particular year. The present analysis includes the entire Norwegian cod fisheries and is carried out using time series data for 2003–2007, examining the annual variations of key economic and technological parameters of the cod fisheries. Based on the results from compromise programming, the article discusses management and policy implications of reallocation of the TAC by vessel groups. 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

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

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

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

How can uncertain fisheries science be linked with good governance processes, thereby increasing fisheries management legitimacy and effectiveness? Reducing the uncertainties around scientific models has long been perceived as the cure of the fisheries management problem. There is however increasing recognition that uncertainty in the numbers will remain. A lack of transparency with respect to these uncertainties can damage the credibility of science. The EU Commission's proposal for a reformed Common Fisheries Policy calls for more self-management for the fishing industry by increasing fishers' involvement in the planning and execution of policies and boosting the role of fishers' organisations. One way of higher transparency and improved participation is to include stakeholders in the modelling process itself. The JAKFISH project (Judgment And Knowledge in Fisheries Involving StakeHolders) invited fisheries stakeholders to participate in the process of framing the management problem, and to give input and evaluate the scientific models that are used to provide fisheries management advice. JAKFISH investigated various tools to assess and communicate uncertainty around fish stock assessments and fisheries management. Here, a synthesis is presented of the participatory work carried out in four European fishery case studies (Western Baltic herring, North Sea Nephrops, Central Baltic Herring and Mediterranean swordfish), focussing on the uncertainty tools used, the stakeholders' responses to these, and the lessons learnt. It is concluded that participatory modelling has the potential to facilitate and structure discussions between scientists and stakeholders about uncertainties and the quality of the knowledge base. It can also contribute to collective learning, increase legitimacy, and advance scientific understanding. However, when approaching real-life situations, modelling should not be seen as the priority objective. Rather, the crucial step in a science–stakeholder collaboration is the joint problem framing in an open, transparent way. 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

In response to the shortcomings of the EU's Common Fisheries Policy, the European Commission has suggested regionalising fisheries management. Examples already exist of the more decentralised management of certain fisheries. Since 2007, the Commission has requested national eel management plans (EMPs) from all EU eel-fishing nations, giving national management bodies considerable freedom to develop their own EMPs. To examine the prerequisites for decentralisation, the Swedish EMP was chosen as a case. The European eel is critically endangered due to overfishing and environmental degradation. Analysis of the Swedish EMP reveals serious flaws: the conflict between the objectives of species and fishery preservation has not been clarified nor is the prioritisation clear. The plan has not been critically reviewed and alternative options are not considered. Though the basic data are uncertain, this uncertainty is viewed as support for not adopting any safety margin. Management is therefore directed towards mitigating the negative effects of fishing and other human activities rather than realising the conservation objective. The efficiency of the various protection measures is also disputable; for example, translocation is problematic, as translocated (i.e., stocked) eels display impaired navigational abilities. Another problematic aspect of this conservation strategy is the slow implementation of the EMP. In conclusion, this study emphasises the necessity of legal and social science as well as natural science research to evaluate the efficiency and implementation of fishery management. 相似文献

This paper undertakes a critical assessment of the present state of fisheries insurance in India. Various factors that contribute to the poor performance of fisheries insurance in the country were identified and ranked based on the responses of fishermen and fish farmers in major maritime states. In the light of the findings, measures such as leveraging the potential of technological interventions, developing innovative institutional mechanisms, bridging the trust deficit amongst the stakeholders and bringing about attitudinal changes through awareness drives are suggested as way forward towards harnessing the potential of insurance as a safety net tool in fisheries sector of India. 相似文献

This article investigates the role and value of user participation in fisheries management. New empirical data on changes in the institutional structure of fisheries management systems is presented by examining the management structure of two Danish fisheries. The analysis focuses on how user participation functions are institutionalized as co-management between administrators and user groups. General lessons for successful user participation in management are deduced. The paper concludes that co-management is able to overcome some of the fundamental problems related to modern fisheries management and that co-management can work as an active and effective management tool rather than as an impediment to efficient management. 相似文献

The present paper presents the practical implementation of the Ecosystem Approach to Fisheries Management (EAFM) in Norway. This involves defining management objectives and developing simple and efficient tools to achieve an overview of management needs and prioritise among these, while integrating broader conservation issues and ensuring stakeholder involvement. A new Marine Resources Act entered into force in Norway in 2009. By integrating conservation and sustainable use as basic principles, the law represents a paradigm shift in the management of Norwegian fisheries. The law indicates which concerns should be addressed, but neither how nor how often evaluations should take place. That is for management to decide. A management principle in the Marine Resources Act confers on the Ministry an obligation to evaluate whether continued fishing at the present scale is justifiable, or whether improved management is required to ensure sustainability. A Stock table, and a table of "Catches of data-poor species" constitute a comprehensive system for monitoring the management principle. Along with a Fisheries table, these tables establish a framework for developing an ecosystem-based fisheries management by providing a basis and tools for prioritising the needs of new and/or revised management measures. 相似文献

Declining catches are typically taken to be a warning sign of overfishing. But in fact, many such declines have been driven by recruitment changes unrelated to stock size, as evidenced by the failure of stocks to recover after reduction in fishing or recovery despite the failure to reduce fishing. Given a declining pattern, supposedly precautionary decisions to reduce fishing should be treated as experimental management options with a high probability of not resulting in the desired recovery to more productive stock sizes. Simple decision tables can be used to compare such experimental options to “wait and see” options that do not involve fishing reductions. A case example with a grouper fishery in Kuwait demonstrates that experimental effort reduction may not be the best policy from a decision analysis perspective, at least when there are substantial reasons to expect recruitment changes unrelated to stock size. In this case, virtual population analysis and stock reduction analysis models indicate either unusually weak recruitment compensation (steepness h < 0.4) or progressive decline in recruitment carrying capacity, possibly caused by decreases in estuarine rearing habitat associated with declining flows of the Tigris and Euphrates Rivers. 相似文献

Market-oriented regional fisheries management—an analysis of four fish regions in the North Atlantic
《Ocean & Coastal Management》2003,46(9-10):917-941
What influence do exchange methods have on ex-vessel prices and what are the potential implications for the regional management of the fisheries? This paper undertakes an empirical analysis of exchange methods and ex-vessel prices for specific demersal fish controlled for fish size and quantity in four North Atlantic regions, including Iceland, North-Norway and Scotland. The methodology consists of a comparative analysis of total average price (TAP) and Anova analysis of monthly average prices of cod and plaice landed fresh during the period 1990–1999. Scotland's auctions have the highest TAPs for the species analysed whilst the lowest TAPs are returned from contract sales in Iceland and North-Norway. Icelandic auctions and Møre–Romsdal auctions adopt intermediate positions in this price hierarchy. Price differences are still present even when correcting for factors such as legal barriers, transport costs from different geographical locations, exchange fees and seasonal variations in supplies. The implications of these findings for current and prospective systems of regional resource and coastal management are then considered and the scope and need for further study is established. 相似文献

Although failures and successes in fisheries management are related to decision making processes, these are rarely analyzed in detail and even less often following quantitative or semi-quantitative approaches. Herein, we study the decision making process for Chile's most important fisheries using a binary decision model. This model evaluates the probability that an annual total allowable catch (TAC) will or will not be modified by the National Fisheries Council (NFC) based on biological, economic, and social factors. We also analyze some aspects of individual voting, particularly whether the members vote against or abstain from voting on the proposed TAC and if they prioritize resource conservation objectives. Our results indicate that the risk of over exploitation for many important stocks in Chile is aggravated by failures at the decision making level: the scientifically recommended TACs for those fisheries that generate higher levels of employment and have greater economic value are normally increased. This analysis shows that the NFC has clearly prioritized short-term economic and social objectives over resource conservation goals. We discuss the need to adjust the composition and functioning of the NFC in order to ensure long-term sustainability of the fisheries. 相似文献

The North Atlantic Ocean has numerous global, regional, and sub-regional instruments for fisheries management. Research for this paper has examined North Atlantic State levels of compliance with these instruments. The study reveals there to be moderate levels of overall compliance, and a latitudinal gradient of compliance with Northern States scoring higher than those in the south. Of particular significance for other global regions, and the future development of international fisheries law, are the findings that: few regional fishery bodies have a systematic program in place to monitor and assess compliance; and despite overall moderate levels of compliance with the conservation and management regimes, most fishery stocks are either overexploited or at risk or collapse. 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

This article presents a decision-making model based on situations that are typically encountered in fisheries management when setting the total allowable quota. The model allows assessing the differences in outcomes when different management institutions make the decision under uncertain conditions. Social preferences are considered to measure the social expected costs raised by different institutions. Moreover, stakeholder participation and the notion of “legitimacy cost” are taken into account, the latter being defined as the cost of actions that stakeholders may take when they do not agree with decisions made by the management authority. Within this context, economic policy choices are discussed in terms of what type of institutions will generate a higher expected welfare depending on social preferences and legitimacy costs in specific contexts. Finally, this article also discusses what aspects should be considered when designing stakeholder and scientific boards in the TAC setting process. 相似文献

In this paper, we address the implications of changing social-ecological feedback links for a sustainable management of coastal regions applying an ecosystem management perspective. This case study focuses on user patterns of fish resources in the Central Baltic Sea archipelago consisting of three sub-regions: Stockholm archipelago, Sweden, the Åland islands and the archipelago of SW Finland. The transition from a region, mainly relying on a mixture of local natural resources towards a region more dominated by the recreational demands of nearby large urban areas, has altered user patterns of fish resources. This transition has partly followed different pathways in the three sub-regions depending on how socio-economic driving forces have been manifested in management actions. Nevertheless, functioning ecosystems are still the basis for the delivery of ecosystem services and a living archipelago system. The significance of capturing and (re)building feedback links into management regarding knowledge on ecosystem services for a sustainable ecosystem management is discussed. 相似文献

Small-scale fisheries are often seen as a solution for ensuring sustainability in marine exploitation. They are viewed as a suitable alternative to industrial fisheries, particularly when considering their social and economic importance in developing countries. Here, we show that the booming small-scale fishery sector in Senegal, in the context of increasing foreign demand, has induced the collapse of one of the most emblematic West African marine fish species, a large grouper Epinephelus aeneus, historically called ‘false cod’ by European fishers. The overexploitation of this species appears to be on account of the increasing effort sustained by a growing international demand and important subsidies, which resulted in a relative stability of the average economic yield per fishing trip and an incentive for continuing targeting this species to almost extinction. It is a critical time for addressing and mitigating the pressure of the small-scale fisheries to prevent declines of fish species that are highly valued by northern markets. A balance between conservation and exploitation is necessary to maintain ecological viability while considering the socio-economic importance of the small-scale fisheries. However, a new strategy is needed for conservation that will consider and articulate simultaneously the concerns regarding unmanaged and growing small-scale fisheries, rampant subsidies and increasing foreign demand. 相似文献
