Fishing for prawn (Macrobrachium rosenbergii) postlarvae is a major contributor to the livelihoods of the coastal poor in Bangladesh, including women. A study of coastal livelihoods along the lower Pasur River in southwest Bangladesh indicates that on average 40% of total annual income comes from postlarvae fishing during the few months involved. However, indiscriminate fishing of wild postlarvae, with high levels of by-catch, has an impact on biodiversity in coastal ecosystems. This has provoked imposition of restrictions on postlarvae collection. The ban has, however, not been firmly enforced because of the lack of alternative livelihoods for coastal poor. A conceptual framework, drawn from an approach to poverty reduction known as the sustainable livelihoods approach, is applied to understanding the role of prawn postlarvae fishing. Evidence from this study suggests that postlarvae fishers faced a number of livelihood constraints, including poor livelihood assets. This paper concludes that wider livelihood options need to be found for postlarvae fishers to support their livelihoods.  相似文献

The Newfoundland fishery has always been a dangerous industry, but since the collapse of groundfish stocks the pattern of risks has changed. To understand these changes we developed the Fishing Vessel Safety Longitudinal Analysis, a linked database comprising Department of Fisheries and Oceans catch and effort records, Search and Rescue Information System records, and Newfoundland and Labrador Workplace Health Safety and Compensation Commission claims. This paper discusses the methodological challenges and solutions associated with linking these databases. We conclude that improved coordination between these agencies is a prerequisite for linking their respective databases, which would in turn offer greatly enhanced opportunities to contribute to fishing safety.  相似文献

Fish producers' organizations (POs) bring together fishers or fish farmers on a voluntary basis so as to ensure the best market conditions for their fish. How fishers perceive and understand their membership experience is crucial to their capacity to learn from each other and adapt when interacting with their environment. These issues are explored by using the case of Propeixe, a Portuguese PO of purse seine fishers. Fishers ‘perceptions’ of their PO experiences are discussed using an analytical framework based on social learning literature. POs appear to stimulate social learning amongst fishers through changes in practices, economic and other incentives, rules and trust in leadership. Moreover, POs add to a simple market structure the properties of network coordination: interdependency and trust as a basis for co-operation. However, POs fail to change modes of interaction and communication amongst fishers. Within the PO network there are informal subnetworks, differing in terms of interests and influences, and disagreeing on problems (e.g. resource status) and on how to deal with them. By enhancing their members' social learning capacity, POs may increase their capacity to learn and cooperate with other actors in the sector. Leadership strategy, to encourage day-to-day dialog and deal with power relations, is essential in this respect.  相似文献

The need for alternative strategies to assist in the monitoring and sustainable management of many commercially important fish stocks is widely recognized. In recent years, greater utilization of fishers’ knowledge has been advocated as a potentially valuable source of ecological data in the assessment and management process. In this study changes in the distribution and relative abundance of common megrim Lepidorhombus whiffiagonis in the North Sea were investigated by comparing three data sources: fishers’ knowledge collected through a structured questionnaire; a vessel’s haul-by-haul catch data from the personal diaries of a single skipper over a 10-year time-series, and catch rates from fishery-independent surveys (IBTS Q1 and Q3). Trends in the distribution and relative abundance of megrim were broadly comparable between the three data sources. The results of the study indicate that, in the northern North Sea, fishers’ knowledge and catch data can provide valid data sources which can contribute to the assessment and management process. A structured approach consisting of a formal agreement, full transparency and commitment between all stakeholders is needed to provide and utilize the necessary data required to provide the most effective and inclusive approach to resource management.  相似文献

An experiment observed the behavior of selected tagged plastic items deliberately released in different habitats of a tropical mangrove forest in NE Brazil in late rainy (September) and late dry (March) seasons. Significant differences were not reported among seasons. However, marine debris retention varied among habitats, according to characteristics such as hydrodynamic (i.e., flow rates and volume transported) and relative vegetation (Rhizophora mangle) height and density. The highest grounds retained significantly more items when compared to the borders of the river and the tidal creek. Among the used tagged items, PET bottles were more observed and margarine tubs were less observed, being easily transported to adjacent habitats. Plastic bags were the items most retained near the releasing site. The balance between items retained and items lost was positive, demonstrating that mangrove forests tend to retain plastic marine debris for long periods (months-years).  相似文献

Stakeholders’ perceptions can influence the success of a fishery. It is important to take these perceptions into account when evaluating the development of a management system and its conservation policies. Structured questionnaires were used to determine fishers’ management and conservation perceptions of the Asturian gooseneck barnacle co-management system. Perceptions were analyzed for the entire fishery and for different socioeconomic factors, these were: location, age, years in the management system, way of access, alternative income sources and income. Fishers’ perceptions varied widely among socioeconomic factors. In fact, a trade-off between management and conservation perceptions was observed for the different categories within each socioeconomic factor, particularly for the years in the management system, location and income factors. Despite the heterogeneity in perceptions, the co-management system has successfully generated a strong conservation ethic in its resource users. Furthermore, as a group, gooseneck barnacle fishers hold positive perceptions on the performance of the management system. When generating management policies, fisheries’ managers must take the heterogeneity of resource users present in the fishery into account. The gooseneck barnacle co-management system demonstrates that even within the same fishery there can be multiple paths to sustainability.  相似文献

Effective management of artisanal fisheries requires understanding fishers, their behaviors, and the drivers that underpin their choices. Behavioral drivers are critical links in understanding the interactions between social and ecological systems and can help inform effective management approaches. A Bayesian Belief Network modeling approach was used to investigate a diverse range of qualitative and quantitative social and ecological drivers of spatial location choice in a multi-species artisanal dive fishery in Costa Rica. Empirical and observer data used to populate the BBN showed the influence of economic factors, environmental conditions as well as social interactions on the decision-making process of spatial location choice. Good governance scenarios represented by Responsible Fisheries Marine Areas Management were analyzed for both hookah and free diving methods to assess the effects of responsible fishing on the fishers and the fishery. Model based-scenario analysis suggests that management interventions should consider the fisher's potential behavioral responses in the context of environmental variability, dependence on cultural assets, and food security. The results show that there is a need to understand fisher's decisions based on broad socio-ecological system understanding and consider the environmental outcomes alongside food security and the cultural significance of different marine species to fishing communities.  相似文献

Promoting and attaining sustainable use of resources through community participation is a central tenet of the European Union's (EU) 2013 Reform of the Common Fisheries Policy. A systematic review approach was used to identify participatory fisheries management arrangements within the EU. Following this, the participatory arrangements were categorized based on the nature of the decision-making arrangement, influence and empowerment of the fishing industry. The study identified 40 management arrangements distributed through 8 member states, with a variety of fisheries and institutional settings for participation in fisheries management in the EU. The majority of the partnerships identified are “Functional participation”, i.e., the participatory arrangement is based in pre-determined goals encouraged by higher decision-making levels in order to increase efficiency of management decisions. Interactive partnership was the highest level of participation identified in the systematic review, and is usually more conducive with local arrangements in coastal and small-scale fisheries targeting low mobility species.  相似文献

There is a general consensus that Small Island Developing States are among the most vulnerable to experience climate injustices. Vulnerability studies of climate change effects on communities have often focused on differences between communities given these climate injustices. However, there is a need to also focus on vulnerability within communities, referred to here as comparative vulnerabilities. Climate justice therefore becomes even more important with more focused attention given to the nuances within groups that fall within the vulnerable category. This article examines comparative vulnerabilities for the fishing community in Jamaica. A survey of 241 fishers from Old Harbour Bay, the largest fishing village in Jamaica, was conducted to examine the level of vulnerability of different fishers to climate change. A vulnerability index was constructed for the community and then comparative vulnerabilities were determined based on socio-demographic characteristics. Overall for the sample 46.9% of respondents would be considered as experiencing a comparatively high level of vulnerability to climate change. Climate change vulnerability was influenced by a number of socio-demographic variables with unique profiles emerging for groups that can be ranked as low, moderate, and high vulnerability. The paper therefore argues that within vulnerable populations there are comparative vulnerabilities based on economic factors and social capital, which must be taken into consideration for adaptation strategies to be implemented. Given these comparative vulnerabilities a more targeted approach to coping and adaptation strategies can then be taken. This will assist in building resilience of these communities that must now adjust to a new normal with climate change effects currently occurring.  相似文献

This essay examines neoliberal forms of resource governance and emerging struggles over control of sea space between coastal fishers, the para-statal oil industry and government authorities in the State of Tabasco, Mexico. The analysis focuses on the changing mechanisms of resource governance and networking related to contested claims over rights to offshore space. The study is based on material collected during ethnographic field research in Tabasco in 2011–2014. By linking a post-Foucauldian approach to governmentality with a Deleuzian perspective on networks, our research examines resource governance as a socio-political arena, constructed in negotiation between multiple governmental, private and civil society actors, including heterogeneous groups from local populations. The study demonstrates how hybrid techniques of resource governance lead to fishers’ socio-spatial displacement, marginalization in the fields of political representation and subjection to ideas of aquaculture entrepreneurship. The ensemble of private regulation and governmental control provides a venue for drawing fishers into clientelist practices of governing while it diffuses questions of responsibility. These modes of governance fragment the fishers’ efforts to mobilize politically, making them rely on less visible networks of contestation shaped by heterogeneous fishing groups, with varying access to resources and political representation. Recent transformations in environmental legislation and the fishers’ mobile tactics of networking may offer opportunities for them to reclaim their resource rights.  相似文献
