To develop a management strategy for informal fishers, a necessary first step is information about the nature of these fishers, their numbers and their socio-economic status. To accomplish this, a survey of socio-economic conditions and use of marine resources was undertaken in 1999 at 20 localities where fishing occurs around the coast of South Africa, concentrating on subsistence or small- to micro-scale artisanal commercial fishers. In each locality, 16–31 "fisher households" were surveyed by questionnaires, focus-group discussions and interviews with key informants. Demographic analyses revealed a low level of migrancy (～5%), an average of 5.3 persons per household and a mean age of 27. Only ～20% of fishers were women and ～15% were children. Poverty was prevalent: unemployment averaged 40.3% (much higher than the national norm of 29.3%). Mean adult equivalent income per month spanned R193–R735 among regions, and was not correlated with size of settlement. Education levels were low, only ～33% of people >20 years old having completed primary school. Migrancy was highest in rural areas (but still much less than the national norm), intermediate in towns and least in metropolitan areas. Household size, participation of women and poverty all followed similar trends. Comparing regions, the East Coast and the province of KwaZulu-Natal had higher migrancy rates, larger household sizes, greater poverty, and greater participation by women in fishing, than on the South and West coasts. Household expenditure on food was ～R450 per month on the South-East and KwaZulu-Natal coasts and ～R750 on the West Coast, and exceeded 60% of income (a measure of "food security") in about half the households surveyed. Harvested resources were sold, consumed or used as bait. In all regions, the two most frequently harvested resources were fish (mostly sold, predominantly fished by men) and intertidal rocky-shore invertebrates (largely consumed, and involving women to a greater degree). On the West Coast, rock lobster Jasus lalandii was the third-most important resource, but on the South and KwaZulu-Natal coasts this species was replaced by estuarine invertebrates. Abalone Haliotis midae, oysters, sandy-beach invertebrates and kelp or seaweeds made up the balance. Diversity of harvested resources increased west to east, following biogeographic trends. The resources could be divided into those of high value (rock lobsters, abalone and, to a lesser extent, fish) and those of lower value (such as limpets, mussels and bait organisms). It is argued that high-value resources are best used to create micro- and small-scale commercial enterprises that can serve to uplift poor fishers. Low-value resources constitute subsistence resources, for which preferential rights should be established for subsistence fishers, including development of exclusive-use zones where necessary. Emerging characteristics of fishing communities that were helpful in defining subsistence fishers in the South African context were poverty, harvest for self-use (whether by consumption or sale to meet basic needs of food security), use of low-technology gear, and concentration of effort on or from shores or in estuaries. At least portions of the catches of all resources are sold, and the majority of equipment is purchased, so any definition of subsistence fishers cannot exclude those who sell part of their catch or do not use hand-made equipment. Some success was evident with co-management, encouraging further exploration of this style of management for subsistence fishers.  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

This paper summarizes recommendations for the management of previously marginalized and neglected subsistence fisheries in South Africa. The recommendations stem from the activities and analyses of a task group appointed by Government and mandated to provide advice about management of the new fishing sector. The following focus areas were identified for attention: planning for implementation; definitions of subsistence fishers and other sectors; assessment and categorization of resources; determination of types of fishing activities; zonation; management systems; training; communication mechanisms; application and allocation procedures; compliance processes; research and monitoring; development of institutional capacity. Subsistence fishers were defined as poor people who personally harvest marine resources as a source of food or to sell them to meet basic needs of food security; they operate on or near to the shore or in estuaries, live in close proximity to the resource, consume or sell the resources locally, use low-technology gear (often as part of a long-standing community-based or cultural practice), and the resources they harvest generate only sufficient returns to meet basic needs of food security. A second group of informal fishers was identified that fishes for profit but cannot be equated to large industrial fisheries, and a new sector was proposed to accommodate these artisanal "small-scale commercial" fishers. Resources were classified for use by these different sectors based on accessibility, fishing methods, cash value and sustainability. In all, 12 different categories of subsistence and small-scale commercial fisheries were identified, and a preliminary list of resource species suitable for different fishing sectors is presented. A multi-tiered institutional management structure is recommended, with the national agency (MCM) controlling issues of national concern, and supporting and coordinating the activities of provincial and local structures. The management agents required for effective implementation were identified and include a dedicated national Subsistence Fisheries Management Unit, provincial management agencies that have the capacity to be delegated authority, Regional Fieldworkers, an independent Advisory Group for Subsistence Fisheries Management, local co-management structures, and community monitors responsible for observing and recording fishing activities and catches. Co-management, involving both authorities and users in joint management, is advocated in preference to previous top-down approaches, because of its potential to improve communication and compliance.  相似文献

Evolution of a new policy for the management of marine fisheries in South Africa led to the Marine Living Resources Act of 1998 (MLRA). Among other innovations, this requires that management strategies be developed for subsistence fisheries. As a prerequisite, definitions and criteria are needed to identify and distinguish them. To achieve this, the Chief Director of Marine & Coastal Management (MCM), the authority responsible for managing marine fisheries, appointed a Subsistence Fisheries Task Group (SFTG) to make recommendations about definitions and modes of management. The process involved successive surveys and consultations with fishing communities, communication with MCM, and a national workshop of all participants. This led to consensus about the following definition:

Subsistence fishers are poor people who personally harvest marine resources as a source of food or to sell them to meet the basic needs of food security; they operate on or near to the shore or in estuaries, live in close proximity to the resource, consume or sell the resources locally, use low-technology gear (often as part of a long-standing community-based or cultural practice), and the kinds of resources they harvest generate only sufficient returns to meet the basic needs of food security.  相似文献

Following the legal recognition of subsistence fishers in 1998 through the promulgation of the Marine Living Resources Act, a Subsistence Fisheries Task Group (SFTG) was appointed by national government to provide recommendations on the management of subsistence fishing in South Africa. To achieve effective management, the SFTG recognized that fishers' needs, perceptions and concerns must be understood and incorporated into future management strategies. As a result, information from fishers was gathered through a five-month research programme that included questionnaire surveys, focus-group meetings, a "roadshow" and a national workshop. Research findings indicated that the fishers' responses centred on four key themes related to (1) the criteria for defining a subsistence fisher, (2) current management practices, (3) resource use and (4) livelihood strategies. Feedback from fishers revealed several issues that have led to uncertainty and dissatisfaction among informal and subsistence fishers. However, these perceptions need to be contextualized within the historical circumstances of fisheries management in South Africa, and it must be recognized that attitudes will only change when management approaches embrace the needs, perceptions and concerns of the users. The information outlined in this paper was instrumental in guiding the formulation of the SFTG recommendations regarding the definition of subsistence fishers and their future management in South Africa.  相似文献

Subsistence fishers were first recognized as a formal fishing sector in South Africa when new fishing legislation, aimed at redressing past inequalities, was enacted in 1998. Little information was available about these fishers, their activities, and the resources upon which they rely. Recognizing the imperative to gain an understanding of the fishers and to consult broadly, the national agency responsible for the management of marine living resources, Marine and Coastal Management (MCM) of the Department of Environmental Affairs and Tourism, appointed a Subsistence Fisheries Task Group (SFTG) in December 1998 to provide advice on the implementation of appropriate management systems for subsistence fisheries. This paper describes the process followed to formulate recommendations that were presented by the SFTG to MCM in February 2000. The activities of the SFTG fell into two categories: research aimed at identifying subsistence fishers and gaining an understanding of their activities and socio-economic profiles; and consultation aimed at ensuring that the needs and aspirations of fishers and the experience of local managers were incorporated. Research included both field-based studies and synthesis of information about comparative fisheries elsewhere. Consultation took the form of local interviews and focus-group discussions, meetings with fishers and a national workshop. A pivotal activity was the development of a clear definition and qualifying criteria for subsistence fishers. A significant outcome was the identification of a separate small-scale commercial sector, previously erroneously lumped with subsistence fishers. Needs of fishers and problems identified during the process provided the basis for recommendations in the following areas: definitions, assessment and categorization of resources, management systems, communication mechanisms, application and allocation procedures, capacity building, compliance, research and monitoring, and funding and staff required for the management of this new sector. An evaluation is made of the opportunities presented by the SFTG process, constraints experienced and lessons learnt, giving important insights that are applicable to other similar processes, yet seldom documented in formal literature.  相似文献

The scarcity of data on fish catches difficult management of small-scale fisheries in developing countries. This study applies fishers’ knowledge to investigate temporal changes in the amount (biomass) and composition (major ecological categories) of fishing resources exploited by small-scale coastal fisheries in the southeastern Brazilian coast. Four hypotheses were investigated: (1) The amount of fish caught reported by fishers would decrease over time. (2) Older fishers would report higher fish catches than younger fishers. (3) Recent interviews would mention large-sized predators less often. (4) Recent interviews would mention less high valued fishing resources. Interviews with 421 fishers in 36 communities in the southeastern Brazilian coast were analyzed, covering a time span of 14 years, from 1995 to 2009. The hypothesis 1 was confirmed, 3 was partially confirmed, while 2 and 4 were not confirmed. Fishers’ age was unrelated to all variables. The results from fishers’ interviews indicated the temporal trends of: (1) a decrease in the biomass of fish caught; (2) an increase in the occurrence of smaller fish and invertebrates in the catch; (3) an increase of high value fishing resources; and (4) maintenance of large predators. The first two indicators suggest excessive fishing, but the later indicators (3 and 4) suggest that the socioecological system of the southeastern Brazilian coast had not yet undergone major ecological shifts.  相似文献

Knysna Estuary supports an estimated 30 full-time and 200 part-time subsistence fishers involved in bait collection, mud crab harvesting, and fishing. The mud prawn Upogebia africana dominates the bait-fishery, with estimated catches amounting to about 3% of the standing stock, suggesting sustainable use. Harvest of Marphysa spp. and Gorgonorhynchus dayi is conducted in a destructive manner. Most of the value of fishing lies in the setline catches of spotted grunter Pomadasys commersonnii and white steenbras Lithognathus lithognathus, whereas small species and individuals, particularly Cape stumpnose Rhabdosargus holubi, are also caught with handlines. Indications are that the linefishery is also sustainable at present. The subsistence fishery is worth an estimated R0.7-R1.1 million per annum, with full-time fishers earning at least R11 000-R17 000 per annum from the estuary. Currently operating under recreational regulations, the fishery is poorly controlled and fails to reach its full potential. The main threat to the estuary from damaging harvests of bait species, such as Marphysa spp. and G. dayi, should be discouraged through heavy penalisation of buyers and traders. Sales of mud prawn could probably be legalised. If off-take rates are found to be sustainable, sales of certain fish species could be legalised if access to the fishery could be effectively controlled under a co-management arrangement.  相似文献

East coast rock lobsters Panulirus homarus are collected by the indigenous people of the Wild Coast, in the Eastern Cape, South Africa, and are sold to coastal hotels and holidaymakers. The South African government has proposed a small-scale commercial fishery based on P. homarus to improve socio-economic conditions in that region. Catch data and information on fishery operations were collected for the artisanal fishery from Coffee Bay, Presley Bay, Port St Johns and Mbotyi, as well as from a commercial buying station near the Mdumbi Estuary, between March 2003 and October 2005. The catch per unit effort of rock lobster poling varied from 13.5 ± 7.7 fisher–1 outing–1 at Port St Johns to 5.9 ± 3.1 fisher–1 outing–1 at Coffee Bay, but the number of fishers or fishing frequency could not be verified. About two-thirds of the lobsters caught (69%) were smaller than the minimum legal size. Hotels and the buying station complied with size limits, but cottages and campers often bought undersized lobsters. Smaller lobsters (females) are caught by poling than by diving. Geographical variations in poling effort and lobster mean sizes could be indicators of heavy fishing pressure on shallow, inshore reefs. The implications of commercialising the fishery and its associated management are discussed.  相似文献

Illegal fishing activities are reported to be on the increase in South Africa, including in its marine protected areas (MPAs). Research is presented on the nature and the scale of illegal fishing in Table Mountain National Park (TMNP) by analysing the numbers of abalone Haliotis midae and West Coast rock lobster Jasus lalandii confiscated from fishers operating in the park's marine protected area between 2000 and 2009. Data were collected from offence logbooks maintained by South African National Parks rangers and managers, the South African Police Services, and interviews with alleged or self-confessed illegal fishers. The research findings indicate that the annual numbers of illegally fished abalone and rock lobsters have increased significantly over time. Spatial analysis suggests that confiscations of abalone occur predominantly on the east coast of the park, whereas higher confiscations of illegally fished rock lobsters occur on the west coast. It is clear from this research that new and more efficient approaches will need to be designed and implemented to minimise illegal fishing in the TMNP MPA. Context-specific conservation targets that acknowledge and integrate social as well as developmental needs are required, and may be essential for limiting biodiversity loss in the longer term, which will ultimately ensure the success of fisheries management and conservation in TMNP.  相似文献

Understanding vulnerability of different types of fishers to the implications of a Marine Protected Area (MPA) is crucial to its long-term sustainability. It helps direct management decisions of the MPA in a way that negative impacts on specific fishers can be mitigated. This study explored the vulnerability within specific groups of fishers, namely, commercial, subsistence and recreational fishers in the context of the largest MPA in the Maldives – the South Ari Atoll Marine Protected Area (SAMPA). SAMPA is subject to a future management plan that is likely to bring changes in how resources can be accessed in the area. In order to explore the vulnerability of the fisher groups, their sensitivity to this change was measured through an exploratory factor analysis and a sensitivity index. It was found that commercial fishers were likely to be the most vulnerable group as the management plan could potentially threaten their livelihood. Subsistence fishers were found to be next, as changes in access to SAMPA will potentially influence how they obtain their dietary protein. Recreational fishers were also found to vulnerable due to the nature of their fishing operation. However, relative to other groups, their vulnerability was likely to be much lower. To ensure strategic measures are designed to alleviate these potential vulnerabilities, this study proposed collaborative stakeholder participation throughout the development process of SAMPA's management plan, and also as a platform to build much needed confidence in MPAs among fishers in the Maldives.  相似文献

Of the southern African intertidal and shallow subtidal trochid and turbinid gastropods, Turbo sarmaticus, T. cidaris and Oxystele sinensis, are the most abundant large species, and therefore obvious targets for a winkle fishery. T. sarmaticus is harvested by recreational snorkel divers, and an application has been made for a permit to experimentally harvest the other two species commercially. This study involves four major aspects, namely morphometrics and flesh yield, shore-based abundance estimates, subtidal abundance estimates, and an estimate of the potential yield for each of the three species off the South-Western Cape, South Africa. Abundance and biomass of the winkles increased from west to east, highest densities being recorded in the low intertidal regions to 2 m depth. Low biomasses of the three species were recorded west of Cape Hangklip and are unlikely to support a fishery there. East of Cape Hangklip, invasion of rock lobsters Jasus lalandii has had a considerable impact on T. cidaris and O. sinensis populations. Consequently, a boat-based fishery with an estimated annual total allowable catch of 75.5 tons for T. cidaris, with a bycatch of 9.9 tons for O. sinensis, can only be considered in the easternmost fisheries-management area between Kleinbaai and Quoin Point. Because previous studies on the harvesting potential of T. sarmaticus off the Western Cape concluded that it was not commercially sustainable, a total allowable catch for that species was not considered. Management options deserving considerations before the commencement of a giant winkle fishery are discussed.  相似文献

In Piriápolis (Uruguay) and Paraty (Brazil), artisanal fishers view fishing as a way of life, rather than just a job. The freedom of fishing and an inherent satisfaction in the occupation figure large in fishers' attachment to it. There are strong indications, however, that the relationship of fishers to fishing is changing. First, while fishers from both areas wish to keep fishing in the future, they are moving into different occupations or supplementing their work in fishing with other employment. Second, artisanal fishers from Piriápolis and Paraty identified fishing as an undesirable occupation for their children because they believe that in the future fishing will no longer be a viable occupation. Nonetheless, despite the wishes of their parents, young men and women in Piriápolis and to a much lesser degree in Paraty continue to become involved in fishing and fishing-related activities. The paper uses a social wellbeing perspective to interpret fisher responses to the changing circumstances they face. Wellbeing is a lens to understand the distinctive features of artisanal fisheries and helps to understand fishers' disenchantment with fisheries governance processes, in a scenario where participation is being promoted by the state in Uruguay and Brazil. The implications of these findings for state efforts to promote fisher participation in governance are discussed.  相似文献

Understanding fishers’ responses to marine spatial closures is important for both resource users and managers. Fishing is a major recreational activity in Australia, and recreational fishers are key local resource users within the Great Barrier Reef Marine Park. In 2004, implementation of a new zoning plan in the park resulted in a reduction in the amount of area available to recreational fishing. A combination of phone, mail, and face-to-face surveys was used to investigate recreational fishers’ choices and spatial redistribution strategies in response to the reduction in fishing area. Approximately 56% of fishers reported losing at least one of their regular fishing locations under the new zoning plan. Fishers generally compensated by shifting their fishing effort to other areas they knew to be good fishing locations, and by finding new areas that they had not exploited previously. Potential implications of these spatial changes in recreational fishing effort for both the marine park and recreational fishers include changes in fishing frequency and satisfaction, reduced fishing quality, restricted access to areas considered to be of high quality for recreational fishing, increased crowding in areas that remain open to fishing, and increased likelihood of localized depletions in popular recreational fishing locations. Identification of the drivers of the spatial distribution of fishing effort, factors affecting fishers’ choices of locations, and adaptation strategies adopted by fishers provide a valuable tool to help understand the impact of spatial fishing closures on fishers and resources.  相似文献

The history, methods, problems and regulation of fishing of the last remaining large queen conch resource in the world, located on a Jamaican fishing bank, are examined. The fishery activities for the queen conch, Strombus gigas Linnaeus are briefly described with the main activities in the industrial sector which produce the bulk of the harvest, which is exported. There are a few large producers harvesting the single major fishing ground of Pedro Bank, southwest of Kingston. These fishers harvested at least 1500 t annually between 1992 and 1998. Management is by licensing, individual quotas and a close season from July to October. Regulations related to CITES are thought to greatly assist in making licensed harvesters provide catch data to the Fisheries Division. The industrial operators have provided funding to undertake stock assessment studies in 1994 and again in 1997. We highlight the focus on management on a participatory consensual approach with meetings with all players in the industry. The conch fishery is thought to be one of the few areas of the Jamaica fishery where there is close and successful collaboration between fishers and the Fisheries Division. It provides an example of how rapid, precautionary, participatory action can provide an adequate basis for management until more definitive scientific information becomes available. The status of the conch fishery is thought to be sustainable at present, once reductions are made to the annual quota.  相似文献

Many of the world's fish populations are overexploited, including Ghana's fish resources. This study examines spatio-temporal trends in fish species composition in relation to biotic, abiotic and anthropogenic factors, towards achieving better-informed management of the beach-seine fisheries. Fishery-dependent data were collected between November 1999 and October 2001 from 94 beach-seine hauls fished at two stations along the Ghanaian coast. The catch consisted of fish, crustaceans, other invertebrates, and macroalgae. Generally, juveniles of species that are exploited by offshore fisheries were found in the catches. Species abundance and their occurrence generally peaked between November and January. Duration of solar radiation and tide level appeared to be important predictors of fish biomass. It is important to exploit the nearshore fish assemblage sustainably because of its nursery role. A co-managed (fishers and government) three-month ban on beach-seining (between May and July) is recommended as the most appropriate control measure towards the sustainability of Ghanaian fish stocks.  相似文献

Understanding resource stakeholders' perceptions of resource condition and management is vital to the formulation of efficacious management policy to sustain natural systems because agreement among stakeholders is likely to result in more effective outcomes. Understanding perceptions is particularly important in the context of coral reefs because threats are often diverse and management options are numerous, and therefore perceptions are likely to be diverse. This study identified the dominant discourses of reef fish decline, and increase, among 119 fishers and fish traders (herein middlemen) in Solomon Islands, and compared these discourses to current scientific knowledge. Discourses were then explored for dominant themes that might improve understanding of resource user perceptions. The findings suggest that certain fisher and middlemen discourses align with scientific understanding of the causal links between human activity and fish stock declines, and that many of the elicited management strategies are aligned with current scientific recommendations. A theme that emerged across the fisher and middlemen discourses of fish decline was a dichotomy in perception between fishing for economic affluence and fishing for subsistence and economic survival. A theme that emerged across discourses of fish increase was a dichotomy between support for command-and-control approaches and support for community-based approaches to management. Differences between some fisher and middlemen discourses were explained by the location in which interviews were conducted suggesting consensual perceptions achieved through local knowledge networks. Similarity between scientific understanding and local perceptions suggests that local resource users are aware of, and might support, fishery management strategies based on scientific evidence. Such strategies must consider factors such as location because resource user perceptions differ between locations and because many threats to the fishery and preferred management strategies are likely to be context specific.  相似文献

El Salvador is one of the most environmentally degraded nations in Latin America, but the declining fishing industry is under-studied compared with deforestation and landuse. This paper examines the reactions to fish stock decline of two generations of fishers in La Union, El Salvador on the Golfo de Fonseca, one of the most important fishing areas in Latin America, using face to face interviews and questionaires. Both older (>35 years) and younger (<36 years) fishers supplemented their income with trading, farming and loans from their relatives in the United States. All older fishers reported larger fish catches five and ten years previously than at present. Previously, fishers caught more fish, but significantly more younger fishers than older fishers reported their fathers caught more fish than they did, indicating an increasing gap in fish catches in recent decades. More younger fishers than older fishers had fathers or male kin who were also fishers, indicating young men were less likely to join fishing without a parent or kin already involved. Minorities of both older and younger fishers engaged in supplementary activities. Environmental degradation disuaded fishers from switching to farming or hunting. The findings are similar to findings elsewhere on the decline of fish resources and generational gaps in environmental knowledge, but differ in that some other studies report fewer opportunities for fishers to access alternative or complementary activities. These findings are relevant to Latin American studies, considering the great value of the Golfo de Fonseca to the livelihoods of Central America.  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

The tropical rocklobster fishery in the Torres Strait, based on the species Panulirus ornatus, is currently managed by input controls. The Australian Commonwealth government’s aim is to transition to a quota management system (QMS) for this fishery. The fishery is complex in terms of international boundaries, multiple jurisdictions and management objectives regulating a mix of commercial and traditional indigenous fishers and a commercial non-indigenous sector. One key objective is to promote indigenous fisher participation to meet their aspirations of achieving a greater control of the region’s fisheries resources. A Bayesian Network analysis has been applied that considers the variability in participation of indigenous fishers under key economic and socio-cultural drivers, such as the availability of a government employment program, lobster prices, social capital and capacity, and infrastructure availability. The model identifies three distinct indigenous fisher groups: full-time, active part-time, and casual lobster fishers. Scenario analyses suggest that changes in the government employment program will have a substantial impact on the relative proportion of fishers in these groups. Similarly, changes in the provision of logistics, infrastructure, and building social capital and capacity are expected to have a significant impact on the occurrence of full-time fishing. As the Commonwealth has an obligation under the Torres Strait Treaty to protect the traditional way of life and livelihood of Islanders as well as promoting employment opportunities for Traditional Inhabitants, it is important that management authorities consider both the effect of management changes for the fishery as a whole and for each indigenous fisher group separately.  相似文献
