Management strategies are challenging to implement in Zanzibar's fisheries because the local people depend upon these resources for basic subsistence. This difficulty epitomizes the vital need for sustainable management: the more people need a fishery, the harder it is to limit fishing to allow regeneration. Comparing fisheries management strategies in two coastal villages in Unguja, the largest island of Zanzibar, Tanzania, this paper confirms the results of existing scholarship that communitybased strategies provide the most promising solutions to this challenge. Interviews with officials from the Department of Fisheries and Marine Resources, Village Fishermen Committees, and 51 fishermen in the villages of Kizimkazi Dimbani and Jambiani reveal the efficacy of strategies where local fishermen are centrally involved. The fishermen interviews reveal ignorance of existing fishing regulations and a lack of enforcement while fishermen at both sites noted that many illegal methods of fishing are still in use and expressed concern that such methods damage fish stocks. The Village Fishermen Committees, a recently implemented community-based initiative, are well attended by fishermen, and constitute a management strength that this paper concludes should be the foundation of future policy. To be successful, these committees need additional educational and financial resources.  相似文献

This paper assessed the socio-economic implications of climate change and vulnerability of fishing communities known as “Koli” living in Mumbai, India. The vulnerability indicators are derived from sustainable livelihood literature and use of multi-criteria analyses and are validated with expert opinions. A survey of two hundred fishermen from five fishing villages in Mumbai was conducted to collect data. The results demonstrate that vulnerability perpetuates due to physical and financial resource constraints among the fishing community. Fishermen from Madh and Worli villages are observed to be more vulnerable and less adaptive due to their inability to use efficient mechanized boats and advanced fishing implements, such as fish finders and GPS (Global Positioning System). The divergence in the vulnerability scores among fishing villages is attributed to the coping strategies, resource availability, knowledge and the benefit derived from the local government. Fishermen have been observing the negative impacts of climate change on their fishing livelihoods. Adaptation strategies to maximize fish catch are observed in such practices as targeting different species and fishing intensively for several days. However, these practices are leading to an imbalance in the common resource pool and biased resource sharing among different groups of fishermen.  相似文献

One of the reasons for the failure of some Marine Protected Areas (MPAs) is the lack of respect for their boundaries and regulations, which intensifies the need to assess the attitudes of stakeholders affected by MPAs. To this end, it is necessary to know the perception and behavior of resource users in these areas in relation to the management process. This study addressed the perception of different groups of fishermen in three MPAs that allow sustainable use of resources on the Brazilian northeastern coast. The perception analysis was based on four aspects: biodiversity conservation, flexibility and adaptability of fishermen, participation in management and opinions about the MPA. The interviewed fishermen (n=100) were classified into natives or immigrants,≥than 40 years old or <40, predominant use of selective or nonselective fishing gear and part or full time fishermen. The results showed that younger fishermen and the ones who use selective fishing gear presented a more conservation prone perception; nonselective fishermen and part-time fishermen were more flexible and adaptable to changes; and younger fishermen tended to agree more with the establishment of the MPAs. Taking these differences in perceptions among fishermen into account could serve as a basis for improvements in the management and conservation of fishing resources, besides helping predict possible future behavior due to changes in management policies.  相似文献

One hundred and twenty-four fishing areas were identified and georeferenced according to fishermen's traditional ecological knowledge. Nearly 80% of the designations of the fishing areas were known by fishermen only and are registered for the first time. Fishermen identify fishing areas according to depth, wooden logs used to anchor fixed nets, gradation of water transparency, and traditional use of certain areas. This study reveals the richness of knowledge held by fishermen, it illustrates their solid straight relationship with the natural environment where they live, and shows the potential uses of TEK for fisheries management.  相似文献

A large number of the marine protected areas (MPAs) designated in Spain have been proposed by public authorities or conservation NGOs in conjunction with their own administrations and other social and economic stakeholders. The only examples to date of MPAs proposed by fishing interests – the fishermen and their organizations – are located at Cedeira and Lira, two small communities in North West Spain. These fishing interests have been involved in these two proposals from the start, including design and development, as well as internal awareness-raising. However, 5 years from the outset, both marine reserves have failed to meet the conditions and essential requirements of a successful fisheries management system. This paper evaluates how the artisanal fishing sector has been identified with the idea of sustainability; and how the role and power relations of the Galician regional administration acquired both the key institutions of co-management and their associated functions which have conditioned the consolidation process of these marine reserves.  相似文献

The dangers associated with commercial fishing are well documented, and fishermen consistently face one of the highest job-related mortality risks of all US occupations. This study explored fishermen's perceptions of these risks in a representative sample of Maine commercial fishing vessel captains. Data were collected on sociodemographic characteristics and risk preferences during sea boardings of working commercial fishing vessels (n=233) along the full extent of the Maine coastline. Trends in perceived risk were explored across the various sociodemographic categories. Fishermen in this study consistently undervalued their true occupational risk, and rated it as average despite consistent evidence to the contrary. Those more likely to downgrade the risk of fishing included state registered vessels and those found to be non-compliant with existing safety regulations. Less educated fishermen and those who come from a fishing family were also more likely to underrate the risks, as were those fishermen who displayed risk-loving tendencies in other facets of their lives such as smokers and those who did not use seat belts. Middle-aged fishermen were also more likely to underrate the risk than the youngest and oldest groups, suggesting that overconfidence grows and then wanes over time. The results of this study strongly suggest that the current safety training and awareness programs targeting fishermen are inadequate. Furthermore, widespread voluntary participation in organized safety training is unlikely since the majority of fishermen believed that the risks were not relevant to their own activities.  相似文献

Much of the research that concerns the impacts of management measures in the eastern Baltic cod fishery has focused on fish stock rather than understanding fishermen's attitudes towards regulations. Hence, there is little information available on fishermen's responses although they are the ones whom the regulations affect most profoundly. This study analyses the views of fishermen towards management measures with an emphasis on fishing closures (marine protected areas, MPAs). Swedish log-book data from 1996 to 2005 were used to describe MPA induced fishing effort displacements. Fishermen argued that MPAs have been inefficient in conservation of cod stock. The enlargement of Bornholm MPA in 2005 caused substantial effort displacement towards areas dominated by smaller sized fish. This contributed to the increased discarding of juvenile cod. Enlarged MPAs also intensified competition between different fleet segments and reallocated fishing areas. To reduce fishing mortality, fishermen suggested days-at-sea (effort) regulation and an effective landings control system for all fleets that exploit cod stocks in the Baltic Sea Main Basin. These measures would better motivate fishermen for mutual rule compliance, which is a prerequisite for a sustainable cod fishery.  相似文献

The 2003 Marine Parks Congress recommended networks of marine reserves to be established covering 20–30% of habitats by 2012. Most marine reserves are, however, failing to meet their objectives, the main reason being attributed to lack of funding. In light of the growing need for effectively managed marine reserves, a survey ascertaining tourists' support and willingness to pay extra to stay at reserves managed by the private sector – Hotel Managed Marine Reserves (HMMRs) was conducted at Whale Island Resort, Vietnam. A total of 97.5% support HMMR, 86.3% were willing to pay, the median amounting to US$9.6/room/night, or 10% of the average room rate, equaling US$67,277 at 60% occupancy.  相似文献

This paper presents the results of a survey of US halibut IFQ holders exploring market participation, opinions about IFQs, and perceived fishery and community effects of IFQs. A four-step mail survey was sent to a stratified random sample of 14% of the total population of quota holders, producing a response rate of 46%, or 506 returned surveys. Survey results suggest that while there is a wide diversity of opinions and perceptions of IFQs, there are some predictable trends in the ways that different groups of fishery participants experience and respond to these programs. Gender, income, age, employment and ethnicity are linked to IFQ market behavior. Income, residency, and ethnicity are linked to attitudes about IFQs. A discriminate function analysis indicates that older individuals, individuals who make less money, and indigenous fishermen are more likely to sell quota and less likely to buy quota. Women and those who are primarily employed in fishing are more likely to be buyers of quota rather than sellers. Fishermen who identify as Alaska Native, residents of small remote fishing communities in the Gulf of Alaska, and low-income fishermen show the least support for IFQ management. Quota holders who have high incomes, do not consider their communities to be dependent on fishing, and residents of Community Development Quota communities express the most support for IFQs. Overall, 84% of survey respondents believe that IFQs are changing the fishing lifestyle; 75% state that IFQs are changing the values in fishing; and 75% perceive of IFQs as private property. A majority of surveyed IFQs holders perceive both positive and negative impacts of IFQs to fisheries and to communities. Perceived positive impacts include: improved safety; improved price; market stability; improved management; consumer benefits; environmental benefits; longer fishing season; and professionalization and stability of the fishing fleet. Perceived negative impacts include: limitations on access and barriers to entry; consolidation and job loss; inequities experienced by small boats, rural fishermen, and crew; creation of a privileged class of fishermen; negative environmental impacts; and less local participation.  相似文献

In the last years, the overall fish industry in the lagoon of Venice has shown a gradual decline. In order to better understand this process, we carry out a socio-economic questionnaire next to the fisherman population. Questionnaire contains significant qualitative and quantitative data that allow us to evaluate the social and the cultural profile of the respondents, including information with respect to the different technological fishing characteristics involved, type and amount of the species harvested as well as the overall productivity of the activity. Furthermore, the questionnaire contains an economic valuation exercise so as to assess in monetary terms the preferences of the fishermen with respect to different alternative policy options that may characterize a future regulation of this economic activity. Estimation results show that fishermen welcome any regulation initiative that is characterized by: (1) banning all fishing activities during the night, (2) allocating fishing concessions areas to each fishermen in a way that minimize the distance between the fishing area and the harbor, and (3) by introducing of a labeling mechanism that certifies the origin of the product. Moreover, the underlying economic valuation mechanism reveals to sensitive to respondent's motivational profile, including the overall trust and confidence that fisherman community places on the current institutional bodies. This result reveals to be of particular significance when attempting the design of an efficient, widely supported regulation of the fishing activity in the lagoon of Venice.  相似文献

Iceland's nationwide privatized Individual Transferable Quota (ITQ) system is over thirty years old but remains a topic of public and political debate, particularly because of the continued effects on small-scale fisheries. A national survey of small-boat fishermen was distributed to: (1) identify major defining characteristics of participants in ITQ and non-ITQ fisheries, (2) document and examine differences in satisfaction with fisheries management, and (3) evaluate the existing options for newcomers to participate in small-boat fisheries. Survey results indicate that Icelandic small-boat fishermen are engaged in multiple management systems within a wide range of boat sizes. Those who held quota were more satisfied with the current ITQ system compared to those who did not hold quota; however, nearly all fishermen were still critical of fisheries management in Iceland and the two major non-ITQ options of lumpfish and coastal fishing were not perceived to offer significant opportunity for entry-level fishermen. Dissatisfaction stemmed from the lack of decision-making power, a distrust of scientific advice, and the perception that the ITQ system did not serve the purpose of protecting fisheries resources, but was rather oriented only toward economic goals. The dynamic nature of Icelandic small-boat fishing livelihoods and the pervasive negative attitudes thirty years after ITQ implementation demonstrate the need for culturally appropriate and equitable fisheries management schemes where success is measured in social as well as economic and biological terms.  相似文献

In order to avoid conflicts when spatially explicit rules are implemented, it is critical to understand the spatial distribution of fishing effort, the migration patterns of fishermen and the use of temporary fishing camps. The migration of fishermen is a process shaped by historical patterns of resource availability, in addition to economic and political factors. We present an example in which a temporary fishing camp used for extraction of benthic resources (Loco: Concholepas concholepas) changed into a permanent one during the study period. Throughout the study period fishing effort (trips) was closely related to the productivity of the different fishing grounds, with more trips directed to the most productive areas. The conversion from a temporary to a permanent fishing camp did not improve the efficiency of the loco fishery, but did allow better access to alternative resources (surf clams) on nearby fishing grounds. The succession from simple shelters to a permanent ‘caleta’ is a common situation along the Chilean coast, motivated originally by resource availability and more recently by the creation of the TURF system. In particular the TURF system converts temporary (resource driven) movements of fishermen into rigid stationary caletas, which creates a number of problems. Temporary fishing camps are common when fishing grounds are far from the base port, but they require specific administrative tools in order to achieve sustainable fisheries management.  相似文献

Bycatch reduction technologies (BRTs) have been developed to limit the incidental capture of non-target marine species in fishing gear, especially those species of special concern. However, in the absence of enforcement, the proven effectiveness of a BRT alone does not guarantee its adoption by fishermen. Human factors also play a fundamental role. This case study was directed at evaluating the willingness of Sicilian longline fishermen to use relatively large circle hooks (size 16/0) as a BRT for the loggerhead sea turtle Caretta caretta. Fishermen were involved in testing circle hooks with their fishing vessels and their own commercial fishing gear, and their opinions before and after trials at sea were recorded. The present study showed the importance of creating a positive human context for testing a BRT. Findings provided additional confirmation about the usefulness of relatively large circle hooks to reduce the bycatch of loggerhead sea turtles on drifting longlines. Interviews before and after trials at sea indicated that socio-economic and emotional factors are essential for successful uptake of BRTs. Crews of large fishing vessels stated that they would be willing to use circle hooks in months with a high probability of turtle captures (June-September) if an economic incentive was provided and there was also public acknowledgement of their efforts. The fishermen's cooperatives association involved in the project is currently evaluating the creation of a product label identifying the harbors where fishing was performed using circle hooks.  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

Marine Protected Areas (MPAs) have long been advocated as effective management vehicles for promoting long-term conservation of marine resources and biodiversity. However MPAs are failing in their conservation goals, impeded by insufficient funds and a heavy reliance by low-income populations on natural resources.Investigation into a potential payment for environmental services (PES) program for marine protection was conducted in La Paz, Baja California Sur, Mexico. Surveys elicited tourists' willingness to pay (WTP) to reduce fishing pressure in Espíritu Santo Marine Park. Interviews with local fishermen investigated necessary levels of compensation in order to cease fishing, by proxy of required salaries in alternative employment outside of the fishing sector.Results indicated that required compensation values outweighed WTP by the tourist sector. Median WTP per trip amounted to US$12.50 and US$30, additional to pre-existing price, for day excursions and longer trips respectively. Median willingness to accept of fishermen was approximately US$135 per week, at time of survey, and required compensation was US$60 per week. Aggregated median WTP was able to cover annual compensation costs for approximately half of the fishing population. That fish stocks were not in collapse, thereby not creating sufficient scarcity and decreasing opportunity costs, and potential high transaction costs were identified as constraints of the proposed PES scheme.However, PES for marine protection should not be dismissed entirely; sites which are less productive and where fishermen's opportunity costs are low will be more suited to such a compensation scheme. Furthermore PES can work alongside existing markets.  相似文献

Artisanal fishing communities are often in conflict with the interests of the oil extraction industry, industrial fishing fleets and tourism. This paper considers Lobitos, a fishing enclave in northern Peru, where the oldest oil settlement in Latin America was established. The primary focus is community organization and development of the fisheries. Using a mixed methods approach, intensive ethnographic observation and analysis of the social networks of the skippers of small-scale fishing vessels was conducted by in-depth interviews with 30 artisanal fishermen, together with a social network survey involving 43 boat captains in Lobitos. The results showed the mistrust and negative attitudes of fishermen towards oil companies and the industrial fishing fleet. However, they expressed positive expectations regarding tourism development, as well as favorable attitudes towards the diversification of fishing activity through tourist services. The networks of acquaintances, social support and exchange of ecological information allowed us to identify three different groups of fishermen according to preferential fishing zones. The skippers of vessels that prefer to fish in intermediate zones have a prominent role, both in terms of local leadership and through the connection with boats belonging to other bays near Lobitos. This subgroup acts as an intermediary in the networks a whole and has an integrated vision of the coastal ecosystem. Network measures and preferential fishing zones can be used as indicators to assess the degree of availability and preparation for the implementation of new uses in the fisheries sector associated with tourism and heritage.  相似文献

The Galapagos Islands are a prime example of a place where fishery management policies have been established without first understanding the behavior of fishermen. Since the creation of the Galapagos Marine Reserve in 1998, there has not been a single study in the archipelago that investigates fishing behavior and the factors affecting this behavior. This paper addresses this gap in the literature by describing and analyzing the decisions of the fishing fleet for the red spiny lobster fishery. It focuses on factors that affect the short-term decisions regarding both participation and intensity of participation in the lobster fishery. This paper finds that the fishing fleet in the Galapagos Islands behaves as profit maximizing firms, because they consider all the benefits and costs that affect both their participation decision as well as their decision about how frequently to be active after they have decided to participate. The results also show that there is a large latent effort in the lobster fisheries that could threaten the sustainability of any initiatives aimed at increasing catchability, prices, or markets. It is expected that this analysis will be valuable to policy makers when designing or improving the management plans for Galapagos fisheries.  相似文献

The fisheries sector is a significant contributor to the Egyptian economy. Recently, issues relating to fishing ports have been highlighted in port planning, availability of facilities, management, and environmental issues. Additional problems include Egypt's lack of specific guidelines for planning and design of fishing ports. This paper aims to assess the current status of five fishing ports (both natural and artificial) located along the Mediterranean coast of Egypt. Data were collected via a questionnaire supplied directly to the fishermen. The questionnaire contains two sections that cover information regarding the fishermen and fishing vessels. There are sections to assess the degree of satisfaction of the fishermen regarding economic, environmental, planning, facilities, and managerial issues. 250 fishermen received the questionnaire. The data were analyzed quantitatively and qualitatively. The results confirm that the fishing ports are negatively affected by a number issues, as well as management deficiencies, resulting in several weaknesses. The main issues include pollution, sedimentation, deterioration of infrastructure, and lack of port facilities. It is recommended that decision-makers should develop monitoring tools and improve infrastructure and services. Recommendations are made for future development to enable the expansion in the fishing industry and improve the sustainability of fishing ports.  相似文献

The European Union has established a framework to achieve or maintain good environmental status in the marine environment by 2020. The Marine Strategy Framework Directive requires the application of the ecosystem approach to the management of human activities, covering all sectors having an impact on the marine environment. However, fisheries in the Mediterranean are far from a systematic implementation of an ecosystem-based fisheries management (EBFM). Aiming to address this issue, this study explores the potential of the relationship between daily yield by vessel (landings and income by species) and vessel position (known via vessel monitoring system) as a tool for fleet management. This approach is possible due to the current dynamics of Mediterranean fleets, with vessels returning daily to the harbour where landings are registered as weight and income by vessel. Moreover, vessels of >15 m total length have been compulsory monitored by VMS since 2005. A bottom trawl fleet that operates in the northwestern Mediterranean was chosen to develop this approach. Different groups of trawlers were identified, which could be linked to the strategies displayed by the fishermen that were mainly driven by the target species dynamics. Accurate knowledge of the fishing targets driving the fleet dynamics and of the fishing strategies at the vessel level (i.e. fishing ground habitat where the fishing pressure is exerted and corresponding landings) are shown to be a feasible tool for fleet management.  相似文献

A vital component of marine policy is the conservation and management of diverse marine resources. In the southeastern US, commercial fishermen target black sea bass (Centropristis striata) with pots from North Carolina to Cape Canaveral, Florida. During the fall through spring fishing season, western North Atlantic right whale (Eubalaena glacialis) distribution overlaps the black sea bass commercial pot fishery. Fishermen interviews revealed that the number of pots set ranged from 3 to 240 and the number of pots set per trawl ranged from 1 to 18. Generally, the amount of gear increased from south to north.  相似文献
