The paper considers the WTO negotiations on fisheries subsidies and the implications that envisaged disciplines will have on coastal developing countries. This is considered in relation to fisheries access agreements in the Central and Western Pacific where several least developed but resource rich island states such as Kiribati and Tuvalu are highly exposed to the risks associated with new WTO fisheries subsidies disciplines that do not consider their particular vulnerabilities. The paper considers some of the issues that coastal developing countries should incorporate into their emerging negotiating positions at the WTO. State-to-Sate fisheries access agreements which are often highly subsidised but where fishing vessel owners pay the equivalent of lump sum tax are paradoxically, the least distortionary and damaging to the environment. Strategies for managing the possible new disciplines are considered.  相似文献

Recreational fishing mortality can have a major impact on coastal fish populations, bringing recreational fishers into conflict with commercial fisheries. This article reviews exclusion zones for commercial fishing, or ‘recreational fishing areas’ as a solution to the conflict between commercial and recreational fisheries. Recently designated recreational fishing areas in the state of Queensland, Australia are examined as a case-study. The goal of recreational fishing areas is to enhance recreational fishing and provide economic opportunities through charter fishing. However, recently designated recreational fishing areas in Queensland have not been thoroughly assessed for their social, economic and environmental impacts and they are not integrated within existing management frameworks for fisheries. The designation of recreational fishing areas is thus a shift away from evidence-based management in Queensland's fisheries and has likely occurred solely for political reasons – there are more voters in the recreational fishery than commercial fishery. In Queensland, excluding commercial fishing on its own is unlikely to result in long-term benefits to recreational fisheries because recreational harvest is a major component of fish harvest for some key species and there is no legislated limit to recreational harvest. Current political attention on recreational fishing areas provides an opportunity for fisheries managers, politicians, conservation groups and the public to discuss what is needed to manage sustainable coastal fisheries. In particular, recreational fishing areas need to be combined with efforts to enhance stewardship among recreational fishers if they are to be successful in the long-term.  相似文献

The economic impacts of recreational fishing in Small Sea Ranch in Gyeong-Nam (GN) province, Korea, are calculated using a multi-regional input-output (MRIO) model to overcome the weakness of a single-region IO model that ignores the spread effects in other provinces. First, multiplier decomposition analysis is conducted to substantiate the existence of strong economic linkages between GN and other provinces by calculating intra-regional effects, net closed-loop effects, net open-loop effects and spillover coefficients. Subsequently, the economic impacts from spending by anglers’ visits to Small Sea Ranch are computed using a 161-sector MRIO model for each of the sixteen provinces in Korea. The results show that there exist strong relationships between the economy of GN and those of the other provinces, and that only around 68% of the economic impacts of anglers’ spending on the total output in Korea accrues in GN, with the remaining impacts (32%) being accounted for in non-GN provinces. This indicates the importance of using a multi-regional framework to estimate the economic impacts of recreational fisheries for a region whose economy relies heavily on the economies of other regions.  相似文献

Most worldwide fish stocks are overexploited, and so exploited beyond the Maximum Sustainable Yield (MSY) and the Maximum Economic Yield (MEY). Not exploiting fisheries resources at MSY or MEY leads to the loss of production and rents from the fisheries. A large part of the EU fisheries are managed based on single species stock assessments; however, in reality, most species are caught together with other species and by different fleets. In multi-species and multi-fleet fisheries, single species assessments, and consequently MSY and MEY reference points, are often not valid, and so the catch recommendations. In this paper it is investigated the MSY and MEY estimation in multi-species and multi-fleet fisheries in comparison to single species assessments. Analyses are applied to the Bay of Biscay demersal fishery using the IAM bio-economic model. The impact of exploiting at MSY and MEY on the optimal effort allocation between fleets with different exploitation patterns and economic structures is analyzed. When accounting for the multi-species nature of the fishery, MSY landings are 0.4% to 2.7% lower than the single species simulations estimates. When accounting for the multi-fleet nature of the fishery, MSY landings are 27.2% to 30.2% higher than the single-fleet estimates. When considering the multi-fleet characteristics, MEY landings are 6.6% higher and profits are 66.5% higher than in the single-fleet simulation. Optimal effort at MEY is lower than at MSY, but when accounting for multi-fleet the optimal effort decreases for some fleets while increases for gillnetters. The results also provide an estimation of the profits at MEY (or costs of not being at MEY). Profits can be then up to 10.7 times larger than the current profits (256 million Euros compared to the current 24 million Euros).  相似文献

In this paper the discard ban policy within the Portuguese fisheries sector is discussed and the opportunities and impact in the fisheries economy that arise from sales of unwanted fish under the new landing obligation are evaluated. The decadal mean price of fish (€/kg, adjusted for inflation) rose from the 1940s until the 1970s, dropping thereafter. The yearly averaged economic income estimated for discards sales between 1969 and 2009 ranged from 419345€ to 2164379€. Discard ban sales could contribute from 10% to 53% of the total landed value and 9–34% of the total catches (landings + discards). Under a discard ban policy, the fishing sector with the largest economic contribution for total discards sales would be multispecies (54%), followed by trawl (26%) and seine (20%). On average, fishing sales contributed with 0.63% to gross domestic production (GDP) between 1938 and 2009. Discard sales can increase 1.07–1.46 times more than the fish landing contribution to GDP. After 1983 the average landings/imports economic ratio was 0.28:1, which means that fish imports surpassed landings economic value 3.57 fold. The discard ban policy can create economic opportunities in the national context thus helping to revitalize some specific fisheries sectors.  相似文献

Tropical small-scale fisheries are highly heterogeneous with respect to a wide range of fisheries characteristics, but that heterogeneity has generally not been adequately studied or considered in management. This study investigated fisheries heterogeneity and the extent to which it is accounted for in management regulations in eight small-scale fishing communities located in floodplain ecosystems of the Amazon basin. Analyses of 29,844 fishery landing interview data revealed that fisheries heterogeneity with respect to gear, habitat, species composition, and total catch and fishing effort was high across all communities, but low over the years in the same communities, indicating that each community must be considered as a distinct management unit. Data analyses also revealed that many important community fisheries characteristics were not accounted for by government- and community-based management regulations. Total catch and fishing effort were largely unregulated; there were no size or closed season limits for one-third of the most important fishery species; and the nursery habitats used by most fishery species were not protected in any fashion. Clearly, increased attention to cross-community fisheries heterogeneity can improve the design and implementation of management regulations. The management problems created by the heterogeneity of small-scale fisheries are discussed, and the potential of the “barefoot ecologist” concept to address them is considered.  相似文献

Small-scale fisheries and the communities they support are often given the protection of designated fishing zones from which non-artisanal vessels are excluded. This paper looks at one example of this approach, the trawl ban introduced in the Gulf of Castellammare (NW Sicily), focussing on the economic sustainability of the artisanal fishery currently operating within the protected area. The consequences of lifting the trawl ban and how far this would jeopardise the sustainability of the artisanal fishery are explored via an analysis of the financial viability of trammel net vessels under alternative assumptions concerning catch rates. The paper also investigates fishermen's attitudes towards the trawl ban and their predisposition either to remain in the fishery or to quit in the event of the ban being removed.  相似文献

The basic structure of the fishing industry in the United Kingdom is outlined, followed by a discussion focusing on six stages of development from the industrial revolution to the present. The industrial focus is evaluated with regard to the catching and shore sides of the industry respectively. The management system is discussed in terms of stakeholder groups, the fisheries resource and marine ecosystem, and regional management. It is concluded that a regional management system closely adjusted to the regional geography of the industry will be most effective.  相似文献

Joint capture of multiple species by multiple fleets results in technical and economic interactions between fleets. This paper develops a bioeconomic model that incorporates interrelationships between fleets for a representative fishery in India. The study analyzes the impacts of overcapitalization on bio-economic sustainability. Results show that a continuation of the current fishing intensity would deplete most commercially important species in the near future. However, an optimal effort re-allocation between fleets would increase fishery profits substantially, although some species would remain unsustainable. The study demonstrates how the newly emerging, large bodies of fishery data can be used for management decisions in developing countries.  相似文献

This article develops and tests three hypotheses concerning the effects of levels of democracy on levels of overfishing in Sub-Saharan Africa. The results show that the more democratic a country is, the more successful it is in protecting marine environments. However, this effect disappears during turbulent times and periods of rapid political change. The analysis also shows that democracy has a stronger effect on environmental performance than do levels of corruption and government effectiveness.  相似文献

Small-scale fishers are often believed to receive marginal earnings for seafood relative to other value- chain actors but proportionate incomes across different traded species are rarely compared. This study compares value chains for 15 species of sea cucumbers between Fiji and Kiribati using data collected on sale prices of dried products (bêche-de-mer) from fishers to middlemen and exporters, export prices and market retail prices in China. Pacific islanders comprised almost all fishers, but represented only some middlemen and few exporters. Proportional increases in prices along the value chains differed greatly among sea cucumber species and between countries. Fishers’ earnings varied greatly among species. The relative share of the end market value they received was negatively related to product end-market value; on average 50% of the end retail value for the lowest-value species but <10% for the highest-value species. Most fishers lacked information about market prices. The gross markup of exporters differed greatly between the two countries. Downstream actors reaped increasingly higher proportions of the product value for higher value species. Variation in sale prices between countries and fishers for the same product indicates a potential for higher earnings to fishers. Improved transparency of prices to fishers could empower them to negotiate higher prices, especially for more valuable species. Upgrading of value-chain governance, e.g. through fisher cooperatives or auction systems, could improve efficiency and fisher incomes, potentially reducing the need for high fishing rates. Such interventions will benefit from understanding the value-chain patterns among different species harvested in multispecies fisheries.  相似文献

Atlantic Canadian fisheries policy exhibits a tension between competing objectives of economic efficiency, and of well-being and equity within coastal communities and small-scale fisheries. The struggle between different actors over these objectives has generated distinct forms of neoliberalism in different regions and fishing fleets. In the lobster fishery, the right to fish has been concentrated since limited-entry licensing policy was introduced in the 1980s. This paper examines actors and events at two scales, including Lobster Fishing Area (LFA) 34 Advisory Committee meetings involving fishermen, representatives of Fisheries and Oceans Canada (DFO), and other stakeholders, and broader scale strategies of the Canadian Independent Fish Harvesters Federation (CIFHF). A Foucauldian perspective aids in understanding how fisheries governance is the product of struggles between the power and agency of individual fishermen, fishing organizations, processing companies, the DFO, the Minister of Fisheries and the courts. While many theorists view fisheries through the lens of the “tragedy of the commons”, alternative tragedies are developing in Atlantic Canadian fisheries. These include rising levels of debt, reduced earnings, vulnerability to financial volatility, loss of fishing rights within communities, and too much processor control.  相似文献

To design an effective capacity management plan for small-scale fisheries one must understand what one is measuring and define its capacity. As recognized by some authors, overcapacity is a problem that generally affects small-scale fisheries just as much as it does other types of fishing. This study aims to estimate fishing capacity, technical efficiency, scale efficiency and capacity utilization in a particular small-scale fishery in the Mediterranean, i.e., the Northwest Sardinian fleet in Italy. A non-parametric approach using a data envelopment analysis (DEA) model was applied to a sample of trawls in order to estimate their economic capacity, and related measurements were taken. The capacity and efficiency with reference to two different alternative scenarios were also calculated.  相似文献

This article provides a historical account of Chinese public policy on fisheries subsidies, and a discussion of problems and limitations resulting from the World Trade Organization (WTO) Doha Round fisheries subsidies negotiation. By analyzing subsidization trends and applying a proportional assessment of subsidized areas, the article tracks the evolvement of Chinese fishery policy objective and priorities. Chinese fishery is not historically significantly subsidized in light of its relatively market-oriented structure and a sustained momentum in reducing marine capture capacity. However, due to the commitment to encouraging qualitative growth and to satisfying a rising domestic demand for fish, the government seeks for adequate policy space to employ fuel, distant water fisheries, infrastructure and various ‘green light’ subsidies. Whether or not such a claim can be accepted as a developmental right not an exception remains to be answered by the revision of current negotiation draft.  相似文献

The results from a survey of Swedish commercial fishers on regulation compliance and attitudes to control and restrictions are reported. According to the responding fishers, 90% of all Swedish catches are reported, in spite of limited control efforts. From an economic perspective we would expect substantially lower levels of compliance. The results also show that the majority of Swedish fishers are in favour of co-management on a regional basis. However, on this and other management issues opinions divert significantly between large vessel operators and small vessel operators, which reveals conflicting interests for such and similar changes in Swedish management of fisheries.  相似文献

The current approval procedure for wind farm proposals in the German EEZ only considers site specific conflict analysis between the wind farm and fisheries. Due to the relatively small spatial coverage of the sites potential opportunity losses to the fisheries are always considered as low or negligible. Cumulative effects on fisheries that will occur once all proposed wind farms are in place are not yet considered adequately. However, those cumulative effects will be quite substantial because, in particular, opportunities to catch such valuable species as flatfish will be considerably reduced.  相似文献

Indicators of the economic performance of fishing vessels are frequently computed in various countries. In this paper, we use different types of information to assess capital value and the economic performance of fishing vessels. On the one hand, field surveys provide technical and financial information on the main components of fishing capital. On the other hand, book values are given in bookkeeping databases. We use both sources of information on fishing capital are used for the same set of vessels, namely the commercial fishing fleet of the French region of Brittany. Based on these two sources, measures of economic performance can be produced for the short term using gross surplus; and for the long term including the cost of capital. The measures of performance obtained are presented and the differences between them are then discussed.  相似文献

The main objectives of fisheries management are generally similar throughout the world. These are often stated in policy documents such as the Common Fisheries Policy and the Magnuson–Stevens Fishery Conservation and Management Act. However, at the local level often the key objectives of management are more detailed, characterised by both the overriding management structure and the status and type of fishery concerned. In this paper, we consider case study fisheries from the UK, France, Spain and Denmark to compare some of the various types of fisheries and fisheries management systems that exist in the European Union. From this, we define the key objectives for each management system.  相似文献
