Identifying socio-economic drivers of small-scale fisheries is a fundamental step to understand impacts and pressures on fishery resources, and the behaviour of seafood trade actors. It is especially relevant for developing countries where such information is usually lacking and fisheries management is greatly needed. To address this gap, this study maps the structure of value chains of fish and marine invertebrates caught by small-scale fisheries from São Vicente, Cape Verde (West Africa), and examines the main socio-economic drivers behind the seafood trade on the island. Specifically, it shows how drivers, such as tourism and the local market, shape the preferences for certain species and how they affect the distribution of income among actors involved in the seafood trade. To collect this information, interviews were done with fishers, small-scale traders, market vendors, and restaurant owners, in all fishing communities of the island of São Vicente, in 2015. Tourism and the local market drive the exploitation of a wide variety of marine species, from small demersal low trophic level fish and marine invertebrates, to large pelagic high trophic level fish species. Moreover, the local seafood market, and especially tourism dynamics, contribute to the unequal distribution of income among actor groups, benefiting mostly restaurant owners due to their direct access to tourist consumers. Such findings have implications for local fishery resources management, food security, and fishing communities’ livelihoods.  相似文献

The cod resources in the Barents Sea constitute the most important fisheries in Norway. In order to reduce resource allocation conflicts among different gear and vessel groups and to ensure profit for all participants throughout the value chain, the sector is thoroughly organized. The institutions established to ensure long-term sustainability, have been developed within the framework of a joint Norwegian–Russian fisheries management regime. However, due to a very high fishing mortality, the cod stock is now under severe pressure. In addition, a major part of the cod fisheries is highly seasonal and unable to be a stable supplier to neither the land-based industry nor demanding international markets. In parallel, cod farming is expected to become a new emerging industry, with potential to copy the success of farmed Atlantic salmon. Many actors within the cod fisheries fear the future competition from the growing cod farming sector. With reference to important attributes that characterize the cod fisheries and cod farming, this paper discusses how a future farming industry may affect the traditional cod fisheries. Moreover, we discuss how the fisheries may be forced to organize in the future to encounter the expected competition from cod farming.  相似文献

Solutions to the problem of discarding in fisheries have been debated for decades. Despite this attention, measures to ameliorate discarding have had limited success. Regulators, researchers, and industry continue to struggle with fisheries management and foregone yield in the face of the continued wastage of valuable resources due to discarding.Waste minimization and by-product utilization are powerful imperatives in other sectors that are also reliant on the harvest of natural resources. This paper considers the performance of these sectors in waste minimization and by-product utilization, with the aim of identifying practices and processes that may be applied to ameliorate discarding in fisheries.This paper describes the handling, utilization, and mitigation of discards and waste in the livestock farming, agriculture, mining, and waste management industries, and in particular, in forestry. In terms of biological impact, economic objectives, and management approaches the harvesting of trees has substantial similarities to industrialized fishing. However, the forestry sector has found ways to utilize almost 100% of the natural product harvest by establishing markets and new products. Analogous developments within the fishing industry could substantially improve sustainability through reduced levels of discarding and wastage. Based on the experiences of these sectors it is suggested that evaluations of potential Management Strategies are developed to specifically examine discard mitigation approaches on a broader scale than previously conducted.  相似文献

The availability of resources and their suitability for subsistence and small-scale commercial fishers in South Africa were assessed and appropriate options for the management of resources recommended. Assessment of current resource utilization and recommendations for future subsistence and/or small-scale commercial use were based on information gathered during a nationwide survey of 144 subsistence fishing communities in South Africa and a review of relevant published and unpublished literature. Current patterns of resource use in three regions of the coast (West, South and East coasts) revealed that most true subsistence fisheries occur in the eastern half of the country. These fisheries are primarily focused on invertebrate species found on intertidal rocky shores and sandy beaches, or in estuaries. Fish are harvested by rod or handline, netting or traditional fishing methods (fishtraps, spearing, baited baskets). No "new" or previously underutilized resources were identified as suitable for subsistence fishing in any of the three regions. The potential for several new small-scale commercial fisheries was identified, but the need to retain certain resources for subsistence fisheries (rather than converting them to small-scale commercial fisheries) was evident in certain areas. Resources with high commercial value were not considered suitable for subsistence fishing, but rather for the introduction of small-scale commercial fisheries. The overall management strategy for the subsistence sector, which is currently in the process of being developed, must ensure sufficient flexibility to be able to take into account regional and site-specific requirements. It will also need to develop co-management structures, protect traditional fishing practices, avoid user conflict and provide for no-take areas, all within the framework of sustainable resource utilization.  相似文献

The science and management of marine resources is increasingly grappling with the use of ecosystem-based fisheries management. Though ecosystem-based fisheries management seeks to unite biological and sociocultural concerns into a holistic framework, people are often seen simply as external drivers of change. The technical questions that are often posed, such as the delineation of boundaries or the strategies of governance, are however more broadly questions concerning the social production of nature. This paper explores these issues by analyzing both the spatial fishing practices of different fishermen and the results of a series of workshops held in New England to solicit opinions about ecosystem-based fisheries management. The paper emphasizes teasing apart the human dimensions of fishing embedded in predominant notions such as fishing effort through more explicit consideration of spatially based resource dependencies and mutual constitution of society-nature.  相似文献

This study investigated how an industrial tuna fishery functions in terms of procedures, practices, governance and finance in the context of Ghana, West Africa. Tuna is Ghana’s biggest seafood export, contributing significantly to the domestic fisheries sector. A case-study approach was used to analyse relevant social and economic factors at the local scale to better understand how the global seafood industry operates in a low-income country. A value-chain framework was adopted to assess market structures, sales pathways and revenue distribution. We also investigated the role of actors engaged in the industry using secondary data, interviews, questionnaires and participant observations. The results revealed a changing organisational structure in tuna production, moving from bait-boat fishing with smaller companies to large-scale purse-seine fishing backed by consolidated Asian seafood companies. Production was found to depend significantly on local female intermediaries for access to funds through prefinancing arrangements. Considerable illegalities were identified within the value chain, highlighting the need for improved partnership and licensing negotiations, and for low-cost marine control and surveillance tools. As vertical integration increases within the industry, the influence of corporations as keystone actors becomes evident for the future social and ecological sustainability of the industry.  相似文献

The pressure on aquatic renewable resources has rapidly increased over past decades as a result of both sustained high demand and technological innovation. The relative scarcity of fishing resources is not new, but it seems today to have become a generalised phenomena for most aquatic ecosystems from local to oceanic scales. Either motivated by the desire to regulate conflicts between groups of fishermen (gears, communities, etc.) or to improve efficiency by internalising part of free access externalities, fisheries management appears fundamentally to represent a process of access rule definition and implementation. Whatever is the instrument (output or input based, regulatory or economic, market oriented or not) it is the structure of access rights that is initially affected. There is nothing original in the fact that increasing relative scarcity calls for property right structure changes. It is also not surprising that in many cases, creating an access right structure provides an opportunity for a market expression of resource value. But in the case of fisheries resource appropriation is not as simple or easy as on land. Mobility and variability of the resource, diversity of fishing techniques interacting over stocks or areas, makes the case more difficult. Furthermore, management instruments are not as similar as the economic theory of management implies. Therefore, there is no straightforward answer. This is the reason why many different routes have been chosen to regulate world fisheries. In practice, efficiency and equity objectives are rarely successfully met. The European Union, with the Common Fisheries Policy and the various local or national management schemes, offers a fair range of such examples. Referring to European examples, the key issues in the debate over fisheries management are considered.  相似文献

Conventional top-down, exogenous approaches to fisheries management have been ineffective in more traditional and small-scale fisheries. Yet, there remains little understanding of the effectiveness of alternative approaches. This case-study of small-scale fisheries in the Comoros examines how effective local fishing associations are at managing common fisheries resources, and provides some understanding of the underlying characteristics of effectiveness. Emphasis is placed on assessing governance effectiveness according to characteristics appropriate within the local context, and on suggesting ways to enhance local institutional strength and capacity to manage resources. Qualitative methods were used to collect data on local governance structures and management tools, fishers’ knowledge and beliefs, and perceptions of the status of fisheries resources in four major fishing villages on the island of Ngazidja. Results show that fisheries management in the Comoros is informally shared between the State fisheries department, a national fishing syndicate, and village fishing associations. Village fishing associations play an active role in fisheries management by collectively designing, monitoring, and enforcing local regulations. Compliance with local regulations is high, primarily due to participatory decision-making, community-monitoring, and strong feelings of solidarity among fishers. Perceptions of the benefits of these regulations are also high. This suggests that by working within these pre-established informal management systems, collective governance of common pool resources can be achieved within communities, and feelings of empowerment and shared responsibility among resource users can lead to effective management practices.  相似文献

Madagascar, the world's fourth largest island, is one of the world's poorest developing countries, and its people depend heavily on marine resources for subsistence and income. Exports of these resources and foreign fishing access agreements are also important, at least from a large-scale economic perspective. In recent years, concerns have been voiced amongst local fishers and industry groups regarding the growth of the country's fishing effort. Despite these concerns, existing knowledge of the scale, composition and trends of Malagasy fisheries remains poor, and there is negligible information regarding unreported catches and illegal fishing in Madagascar's waters. Small-scale fisheries, which are often substantial in developing countries such as Madagascar, are often unreported or underestimated. Unfortunately, fisheries legislations, management plans and foreign fishing access agreements are often influenced by these incomplete data, leading to serious over-estimations of resource availability. This also appears to be the situation in Madagascar, where the reconstruction of total catches by all Malagasy fisheries sectors conducted here showed that total catches between 1950 and 2008 were twice the volume reported by national fisheries agencies. Most importantly, much of the subsistence sector is missing from official statistics, and signs of decline have already been observed in several stocks, suggesting that current levels of catches are likely to be exceeding sustainable yields. This has profound implications for the economic and ecological sustainability of fisheries, as well as food security in a country where people rely heavily on the ocean for their daily protein needs and livelihoods.  相似文献

Decisions regarding the selection and implementation of management strategies that constrain fishing pressure can be among the most difficult choices that fisheries managers and stakeholders must make. These types of decisions often need to be confronted in a data-limited context, where few if any management measures are currently in place or fisheries are managed independent of adequate scientific advice. This situation can sometimes create a high risk of overfishing and potential loss of economic and social benefits. To address this situation, simple model-free indicator-based frameworks have the potential to be effective decision-making platforms for fisheries where quantitative estimates of biomass and fishing mortality based reference points are lacking. In this paper, a multi-indicator framework is developed that enables decision-makers to proceed with management decisions in data-limited situations. Model-free indicators are calculated using trends in observed data, rather than stock assessment derived estimates of biomass and fishing mortality. The framework developed is adaptive so that adjustments to catch or effort are recursive and can respond to changing environments, socioeconomic conditions, and fishing practices. Using stakeholder-defined objectives as a foundation, indicators and reference points of fishery performance are chosen that can be evaluated easily by undertaking analyses of available data. Indicators from multiple data streams are used so that uncertainty in one indicator can be hedged through careful interpretation and corroboration of information from alternative indicators. During the adaptive management cycle, managers and stakeholders evaluate each indicator against the associated reference points to determine performance measures, interpret the results using scientific and local knowledge, and adjust fishery management tactics accordingly using pre-defined harvest control rules. The framework facilitates the interpretation of situations in which performance measures suggest divergent stock abundance or productivity levels. A case study is presented on this framework's development for conch and lobster fisheries of Belize.  相似文献

Taiwan used to have the biggest precious coral fisheries industry in the world. However, due to changes in the fishery, including increased fishing restrictions and the replacement of obsolete vessels, the scale of the industry had been gradually reduced since 1979. Unfortunately, the initiative proved to be poorly managed and resulted in an increase in illegal, unreported and unregulated (IUU) coral fishing. This forced the government to review and amend the precious coral fisheries management regulations, which had been in place for decades. The Taiwanese government introduced stringent monitoring, control and surveillance (MCS) management methods, already used in deep water fisheries, as a precautionary approach. At the same time, an investigation and evaluation of existing resources was carried out. Together, these initiatives were introduced in order to encourage the domestic industry to adopt the concept of ecosystem-based fishery management.  相似文献

This paper explores the failures of the quota allocation system in the hake fishery in Walvis Bay, Namibia through an examination of the complex processes that link commodities, labour, production, markets, and knowledge in the industrial setting. The relationships between state regulations and public nature point to a specific engagement in which nature is divided, distributed, and owned, namely through the market driven prospects of transferable quotas. This article examines fishing quota as a set of relations that links the transformation of fish from biological organism to global product and thus weaves science, the state, markets, and social relationships into an entanglement of different forms of capital. In this context, the tension between the quota holder, the value of that quota, and their participation in the industry reflects a complex network of capital mediated through various strategies. Based on ethnographic research in the Namibian trawl sector, this article surfaces these modes of capital in the dynamics of the fishing operations. As such, the fishing industry, the company that holds the fishing rights, the government׳s role in quota allocations, the vessels, gear, and technologies, and the relationships and roles of the crewmembers and skippers׳ knowledge all contribute to a particular formulation of fishing practices. Fisher׳s knowledge in industrial fishing practices becomes a site in which to explore the consequences of ITQs that may also begin to destabilise the neoliberal business model for fisheries in times of crisis.  相似文献

Salmon fishing used to be the primary source of income in many rural areas of Arkhangelsk oblast in northwest Russia. People who settled in the area received a name Pomory, from Russian po moriu, meaning by sea, because their subsistence activities became marine fishing and hunting and seafaring. Local fisheries have undergone significant changes as post-Soviet Russia embraced the market economy and the state introduced fishing concessions. The current Russian law only allows fishing for salmon through officially registered recreational or commercial fisheries. Both these options are often either unavailable or unaffordable to rural dwellers, which leaves them with limited or no legal access to their traditional salmon fisheries. There has been a growing concern for protecting communities’ fishing rights among wider society in Arkhangelsk oblast. City activists promoted Pomory identity and appealed to the Russian government to grant Pomory an indigenous status to secure their access to fisheries. Although Pomor activism did not reach most of its proclaimed goals, it has contributed to promoting the image of Arkhangelsk oblast as a homeland to Pomor fishing. This image has played an important part in what Arkhangelsk authorities have called socially-oriented fisheries management. Officials have made good attempts to better accommodate rural communities’ access to fishing resources. Yet, these attempts have failed to include fishermen as active participants in the process. This paper looks at constraints on community participation in fisheries management in Russia. It considers both historical and contemporary reasons for the low participation of local community in fisheries management.  相似文献

This is the first regional study of artisanal fisheries in Pacific Island countries and territories that demonstrated that the future of the region's artisanal fishery sector and the livelihood of coastal communities will be highly dependent on alternative subsistence and income sources, which are necessary to reduce fishing pressure to a sustainable level to maintain ecosystem services and food security. The overall objective of this study was to identify socio-economic indicators and drivers to improve the understanding of the dynamics between socio-economic conditions and current exploitation levels of finfish and invertebrates of coastal communities in 17 Pacific Island countries and territories. We showed that exploitation rates and thus possible overexploitation are not solely the consequence of a simple demographic growth process but are in fact a result of the choices people have. Our results confirmed a close relationship between resource exploitation rates and economic development at the national level and the availability of alternative income opportunities at the community level. Multivariate analysis results suggest that communities in countries with somewhat unfavourable conditions and limited access to alternatives and fishing households in communities with overall favourable economic conditions are at highest vulnerability as they have the highest dependence on coastal fisheries resources. Alternative economic opportunities at the national scale and availability of alternative income at the community level vary significantly between cultural groups. Based on our results, the development of management strategies with realistic expectations of ensuring livelihood of coastal communities and sustainable resource use in Pacific Island countries and territories requires a hierarchical and integral approach. Major drivers identified at the regional, cultural and local levels should be used to identify priorities, to assess overall advantages and limitations at the different levels as well as the vulnerability of communities targeted, and to develop strategies accordingly.  相似文献

Substantial economic opportunities have been identified in many Australian fisheries but may remain unimplemented due to the perception that the role of government is to ensure harvests are biologically sustainable, while economic decisions should be left to the commercial industry. This paper explores the role of government in driving changes that increase revenue and profit from fisheries (termed economic benefit). Australian fisheries resources are managed by eight different jurisdictions. While each have separate legislation, there is invariably a responsibility to manage on behalf of, and to the benefit of the public, who are the owners of the resource. This paper uses case studies to explore how government can struggle to determine the public interest, separate this from private interests and then implement management changes to ensure the public utility is maximised. Common problems were: (i) overarching economic objectives, which define who should benefit, were often ambiguous and open to interpretation; (ii) the public interest was usually abstract and often under-represented in decision-making processes, (in contrast to industry, who have direct representation); (iii) special interest groups were often able to lobby against changes; and (iv) government was often reluctant to seize opportunities to increase economic benefit when there was significant industry opposition to management changes. In drawing attention to these challenges and how they have been overcome historically, it is argued that government has both a role and requirement under their legislative objectives to take the lead in implementing measures that increase the economic benefit from Australian fisheries.  相似文献

Although overexploitation of commercial fish stocks in European waters has been in the public debate now for more than 20 years, the European Union has so far failed to implement sustainable fisheries management. Millions in subsidies paid to the fishing industry have led to significant excess capacity in the fishing fleet. Various feeble attempts to stop overexploitation of marine resources have failed. The cause is that fishing policy is highly dominated by short-term socioeconomic interests. There is an urgent need for a new fisheries management system in Europe that supports reductions in the fishing fleet, increases responsibility among fishers and guarantees long-term conservation of natural marine resources.Transferable rights to fish have proved a reliable and effective means of creating incentives to conserve marine resources. By strengthening individual fishing rights under flexible quota management systems, the EU Member States could, within the Common Fisheries Policy, make a significant contribution to conserving fish stocks, to reducing excess capacity and to raising the profitability of the fisheries industry. A closer look at existing reservations against a flexible management system shows most of the objections to be overstated or capable of resolution.  相似文献

A large gap has been identified between the current and optimal economic performance of wild-capture commercial fisheries in Australia. Economic approaches have the potential to assist fisheries to bridge this gap, such as bio-economic models that combine biology with fishing costs to evaluate the economic performance of a broad range of management measures. Economic objectives are prevalent in overarching Australian fisheries legislation, however economic data is often not collected and economic analyses or instruments not broadly applied. This paper reviews selected Australian fisheries to demonstrate the accrued economic benefits from applying formal bio-economic models and conducting empirical analyses of the impact of supply on product value. Challenges to the implementation and continued use of economic analyses and instruments are discussed including: (i) short-term transition costs and associated trade-offs between ecological, economic, social and political objectives; (ii) scarce logistical and financial capacity to collect and analyse economic data; (iii) a lack of desire among industry to change and transition to economic targets such as maximum economic yield (MEY), particularly when it is associated with lower catches; and (iv) a lack of economic literacy among fisheries managers and industry. It is contended that many of these challenges initially arise from an absence of clearly identified and prioritised objectives within overarching legislation and management plans. Once objectives are prioritised, limited resources can be allocated more efficiently to improve data collection, economic analysis and increase awareness as well as education of managers and industry.  相似文献

Given the increasing competition for marine resources, regulatory strategies that benefit multiple stakeholders are increasingly important. Offshore wind power generating facilities are becoming more common in the marine environment and alter the characteristics of the fisheries in the surrounding area. Floating wind turbines can act as fish aggregating devices (FAD), thereby increasing the catchability for some species. Many marine recreational fisheries are open access without effort restrictions; therefore, control of total harvest is difficult. Creating a limited entry recreational fishery and excluding commercial fishing from the area surrounding offshore wind turbines may aid in controlling total harvest and may benefit several important stakeholder groups: (1) recreational and commercial fishermen in terms of higher recreational catch rates and potentially higher overall yield, (2) fisheries managers in terms of more precise control of recreational fisheries harvest, and (3) owners of offshore wind power facilities in terms of reduced risk of damage to infrastructure due to fishing activity. We discuss the compatibility of wind power facilities and fisheries, conditions conducive to this compatibility, and provide an example from a proposed offshore wind power facility in the Adriatic Sea and its potential to affect the fisheries management there, particularly for bluefin tuna (Thunnus thynnus).  相似文献

The Falkland Islands has successfully met many challenges in the management and development of its fisheries resources over the last 20 years. To meet a new set of challenges the current licensing system based on the allocation of non-transferable, variable duration licences to individual vessels is being replaced by a system of long-term individual transferable rights owned by Falkland Islanders. The anticipated gains are enhanced economic performance of the sector because fishing businesses have increased security and flexibility, rapid diversification from harvesting into value-added activities and increased international competitiveness as poorly performing companies sell rights to well performing companies. Implementing a rights-based regime in a small coastal state is challenging. Thin markets for rights, a desire to maintain local control of fishing rights, and a dependence on foreign direct investment in the fisheries sector are key considerations in the design of an effective and efficient management regime. Starting operation in 2006/07, the new rights-based management system provides a model for small coastal states or small industrial fisheries that previously had considered rights-based systems too complex to implement and administer, despite the inherent advantages of rights-based management.  相似文献

This study investigates the local social and fisheries impact of formal fisheries policies in Bahía de Kino, one of the most important fishing villages in terms of extraction of benthic resources in the Northern Gulf of California, Mexico. The paper focuses on cross-scale institutional interactions, describing how existing formal policies are functioning on the ground, how these policies interact with local arrangements, and how this interaction may affect the incentives of different actors towards sustainable fisheries. Besides providing lessons on how the performance of a local fishery could be improved, this paper addresses the question of whether the formal institutional structure of Mexican fishing regulations is effective in promoting responsible behavior by small-scale fishery stakeholders. It is argued that the design of the most widely used management tool to regulate access to marine resources throughout Mexico -the permit (licensing) system- provides the wrong incentives for sustainable-use. Granting secure rights to resources to those actively involved in the fishery is a necessary step for promoting sustainable fishing practices.  相似文献
