Cost benefit analysis of fisheries management plans

The management of freshwater fisheries in France is generally entrusted to angling associations, which are in turn grouped into departmental federations. These associations, act under State supervision to protect the aquatic environment and develop recreational fisheries. The National Fishing Council has developed a general method for the formulation of departmental fishery management plans. More than half the departments of France have been involved in this programme since 1995. The approach focuses on the potential number of adult wild fish in each homogeneous ecological unit called a 'context'. The cost of any rehabilitation work needed to restore habitat and to place the context under self-sustaining management (called 'patrimonial management') is estimated. Examples of the way in which cost-benefit analysis helps determine the economic viability of management plans are drawn from the Indre and Hérault, two departments with contrasting ecological and fishery situations. The analysis takes into account the value of wild fish in relation to stocked fish.     

Catch-and-release science and its application to conservation and management of recreational fisheries

Abstract  Catch-and-release angling is a well-established practice in recreational angler behaviour and fisheries management. Accompanying this is a growing body of catch-and-release research that can be applied to reduce injury, mortality and sublethal alterations in behaviour and physiology. Here, the status of catch-and-release research from a symposium on the topic is summarised. Several general themes emerged including the need to: (1) better connect sublethal assessments to population-level processes; (2) enhance understanding of the variation in fish, fishing practices and gear and their role in catch and release; (3) better understand animal welfare issues related to catch and release; (4) increase the exchange of information on fishing-induced stress, injury and mortality between the recreational and commercial fishing sectors; and (5) improve procedures for measuring and understanding the effect of catch-and-release angling. Through design of better catch-and-release studies, strategies could be developed to further minimise stress, injury and mortality arising from catch-and-release angling. These strategies, when integrated with other fish population and fishery characteristics, can be used by anglers and managers to sustain or enhance recreational fishing resources.     

Economic evaluation of inland fisheries in England and Wales

Recreational inland fisheries are recognized to have considerable socio-economic benefits, not only for individuals participating directly but also for others in both local and wider communities. In England and Wales the Environment Agency (EA) has a duty to maintain, improve and develop inland fisheries. At present, there are no recent economic evaluations of the whole range of UK inland fisheries for the EA to refer to when confronted with resource issues. There is a particular need to explore the benefits of fisheries to the wider community, in order to secure more resources for management and protection of fisheries. Preliminary results from a multi-modular project to study the economic values associated with recreational fisheries in England and Wales are presented. Topics examined included recreational anglers' consumer surplus, general public non-use values of fisheries, social benefits of recreational fishing and impacts of fisheries on local communities.     

Diagnosis and management of small-scale fisheries in developing countries

Small‐scale fisheries (SSF) make important but undervalued contributions to the economies of some of the world’s poorest countries. They also provide much of the animal protein needed by societies in which food security remains a pressing issue. Assessment and management of these fisheries is usually inadequate or absent and they continue to fall short of their potential as engines for development and social change. In this study, we bring together existing theory and methods to suggest a general scheme for diagnosing and managing SSF. This approach can be adapted to accommodate the diversity of these fisheries in the developing world. Many threats and solutions to the problems that beset SSF come from outside the domain of the fishery. Significant improvements in prospects for fisheries will require major changes in societal priorities and values, with consequent improvements in policy and governance. Changes in development policy and science reflect these imperatives but there remains a need for intra‐sectoral management that builds resilience and reduces vulnerability to those forces beyond the influence of small‐scale fishers.     

Examining changes in participation in recreational fisheries in England and Wales

Abstract Inland fisheries in England and Wales have high economic and social values. Managing participation to maximise fishery performance is key to maintaining this status. The capital value of fishing rights for migratory salmonid fisheries is €165 million. Coarse fisheries contribute €1030 million to the economy. The central tenet to increasing participation in recreational salmonid fisheries is that an increase in stock size will result in more anglers accessing the fishery. This was examined for salmon on the rivers Usk and Lune where exploitation restrictions increased the number of salmon available to anglers. On the River Lune, the number of salmon available post‐intervention increased by 66%. There was no significant increase in catch while the number of anglers decreased by 16.3%. On the River Usk, the closure of the net fishery potentially resulted in an additional ～1200 salmon being available. Following closure, there was no significant change in rod catch or in the number of anglers. Increased participation is dependent less upon stock manipulation for coarse fisheries and more upon facilitating the activity. In recent years, urban fishery development programmes have provided improved access to local fishing opportunity. Also, new anglers have been targeted through campaigns such as Get Hooked on Fishing and the Scout Angler Badge.     

Fisheries management in inland and coastal waters in Denmark from 1987 to 1999

Fishing is a major recreational activity in Denmark, involving both inland and coastal waters. Anglers, aged 18–67, and amateur fishermen, aged 12–67, must hold a valid fishing permit. Fees are used for stocking, river restoration and fisheries research. All proposals for stocking inland waters require stocking plans based on the carrying capacity of the aquatic habitat in question. All stocking is undertaken using hatchery-reared fish that are the offspring, either of wild fish caught in nature for subsequent stripping, or of more or less domesticated fish stocks that have lived in captivity for several generations. Stocking is also subject to genetic guidelines. This paper reviews the status of fisheries in Danish inland waters, their regulation, socio-economic aspects, stocking, aquaculture and the main problems and trends.     

Social, economic and cultural perspectives of European inland fisheries: review of the EIFAC symposium on fisheries and society

The contributions presented at the EIFAC Symposium on Fisheries and Society in 2000 are reviewed. There have been considerable advances in many sectors of inland fisheries over the past decade. Nowadays the value of inland fisheries to society is generally better understood and increasingly recognized. However, it was recognized that the allocation of fishery resources and their management could still be made more effective through more extensive application of the recent approaches and techniques discussed during the Symposium and reviewed in the paper.     

Individual transferable quotas and ecosystem‐based fisheries management: it’s all in the T

Recent articles in high‐profile journals advocating the widespread establishment of economic rights‐based approaches for managing fisheries has re‐kindled the debate over the efficacy of incentive‐based vs. regulatory‐based management approaches. Inspection of these works, written from the particular perspectives of economics, fisheries biology, or marine ecology, reveals that advocates of rights‐based regimes such as Individual Transferrable Quotas are sometimes recommending these policy instruments for quite different reasons. Hence, the advantageous attributes of rights‐based approaches from the perspective of one discipline may be quite different when seen from the perspective of another discipline. This is of concern as it exposes a tendency for particular disciplines to consider only the advantages of rights‐based approaches, such as establishing a harvest cap, but to implicitly discount the disadvantages such as less attention being paid to critical ecological and ecosystem issues.     

Ecosystem goals can reinvigorate fisheries management, help dispute resolution and encourage public support

This paper argues that if rebuilding of ecosystems is adopted as the goal for fisheries management, recent disputes over political interference in the scientific process would be reduced in severity through a clarification of objectives and procedures. The use of an ecosystem approach enables alternative end states of current harvesting policy to be evaluated more objectively. Moreover, support from the general public for fisheries policy is likely to be greater when they are given a clear and important role to play as sentinels reporting upon the status of a wide range of organisms in aquatic ecosystems.     

Sea cucumber fisheries: global analysis of stocks,management measures and drivers of overfishing

Worldwide, most sea cucumber fisheries are ineffectively managed, leading to declining stocks and potentially eroding the resilience of fisheries. We analyse trends in catches, fishery status, fishing participation and regulatory measures among 77 sea cucumber fisheries through data from recent fishery reports and fishery managers. Critical gaps in fisheries biology knowledge of even commonly targeted species undermine the expected success of management strategies. Most tropical fisheries are small‐scale, older and typified by numerous (>8) species, whereas temperate fisheries are often emerging, mono‐specific and industrialized. Fisher participation data indicated about 3 million sea cucumber fishers worldwide. Fisher participation rates were significantly related to the average annual yield. permanova analysis showed that over‐exploited and depleted fisheries employed different sets of measures than fisheries with healthier stocks, and a non‐metric multidimensional scaling ordination illustrated that a broad set of regulatory measures typified sustainable fisheries. SIMPER and regression tree analyses identified that the dissimilarity was most related to enforcement capacity, number of species harvested, fleet (vessel) controls, limited entry controls and rotational closures. The national Human Development Index was significantly lower in countries with over‐exploited and depleted fisheries. Where possible, managers should limit the number of fishers and vessel size and establish short lists of permissible commercial species in multispecies fisheries. Our findings emphasize an imperative to support the enforcement capacity in low‐income countries, in which risk of biodiversity loss is exceptionally high. Solutions for greater resilience of sea cucumber stocks must be embedded within those for poverty reduction and alternative livelihood options.     

Aspects of fisheries and water resources management in England and Wales

Freshwater fish populations in England and Wales form an important resource with up to 2.2 million anglers involved in the recreational fishery. The resource consists principally of indigenous and naturalised cyprinids, and strongholds of species endangered elsewhere in Europe. Each component is under pressure from a range of sources including water abstraction and climate change. Water resources are under significant pressure and droughts in parts of England and Wales exposed the fragility of water supply systems. Climate change is a major concern, driving a re-assessment of water supply yields. There are no objective methods available to predict changes in fish communities likely to arise from different water resource management options, except for simple systems. It is difficult to manage water resources using anything other than a precautionary approach. Accurate assessment of environmental requirements are required to strike the right balance between the needs of aquatic ecosystems and of economic efficiency.     

A new role for MSY in single-species and ecosystem approaches to fisheries stock assessment and management

In 1977, Peter Larkin published his now‐famous paper, ‘An epitaph for the concept of maximum sustained yield’. Larkin criticized the concept of single‐species maximum sustained yield (MSY) for many reasons, including the possibility that it may not guard against recruitment failure, and the impossibility of maximising sustainable yields for all species simultaneously. However, in recent years, there has been a fundamental change in the perception of the fishing mortality associated with MSY (F_MSY) as a limit to be avoided rather than a target that can routinely be exceeded. The concept of F_MSY as a limit is embodied in several United Nations Food and Agriculture Organization (FAO) agreements and guidelines, and has now been incorporated into the US Magnuson–Stevens Fishery Conservation and Management Act. As a result, the United States now requires the development of overfishing definitions based on biological reference points that treat the F_MSY as a limit reference point and must also define a lower limit on biomass below which rebuilding plans with strict time horizons must be developed. This represents a major paradigm shift from the previously mandated (but often unachieved) objective to simply maintain fishing mortalities at levels below those associated with recruitment overfishing. In many cases, it requires substantial reductions in current fishing mortality levels. Therefore, the necessity of the new paradigm is continually questioned. This paper draws on examples from several fisheries, but specifically focuses on the recent US experience illustrating the practical difficulties of reducing fishing mortality to levels below those corresponding to MSY. However, several studies suggest that even more substantial reductions in fishing mortality may be necessary if ecosystem considerations, such as multispecies interactions, maintenance of biodiversity and genetic diversity, and reduction of bycatch and waste, are taken into account. The pros and cons of moving beyond single‐species assessment and management are discussed. A US plan for improving stock assessments indicates that even a ‘basic’ objective such as ‘adequate baseline monitoring of all managed species’ may be extremely costly. Thus, the suggestion of Larkin (1983, 1997) that the costs of research and management should not exceed 10–20% of the landed value of the catch may preclude comprehensive ecosystem management. More importantly, neither single‐species nor ecosystem‐based fisheries management is likely to improve appreciably unless levels of fishing capacity are aligned with resource productivity, as is currently being promoted by FAO and several individual nations.     

Typology of landowners in Norwegian salmon angling: attitudes towards river owner organisations and management actions

Abstract Atlantic salmon, Salmo salar L., recreational fisheries in Norway are facing shorter seasons and harvest restrictions because of low adult migration runs. Private fishing‐right holders (landowners) are important stakeholders, being co‐managers of the stocks, owners of salmon habitat and suppliers of angling. Landowners saw measures addressing salmon farming and Gyrodactylus salaris (Malmberg) as the most important management actions to strengthen stocks and downplayed actions restricting their own activity or gain. The results showed a need to build knowledge and improve communication between landowners and river owner organisations about the effects of stocking, catch and release, and other management actions. Four distinct landowner types were identified, based on their objectives for the fishing right. The diversity in the landowner group suggests managing angling tourism will be challenging, and cooperation is required to manage salmon stocks. Policy instruments to facilitate cooperation are discussed for each landowner type.
