Plans by government to accelerate the establishment of a national representative system of marine protected areas (NRSMPAs) in Australia have caused increasing disquiet within the fishing industry. Rock lobster fishers have raised concerns regarding plans to establish large “multiple‐use” MPAs that may or may not contain a substantial no‐take component in the continental shelf waters adjacent to the coast. Key industry concerns including the potential impacts on present and future harvest rates are examined. The industry response to government MPA policy in each of the major jurisdictions is outlined. An industry position developed at the National Rock Lobster Congress in Perth, Western Australia (September 2003) is put forward. The position advocates the need for an adjustment scheme to account for displaced effort, the need for government commitment to the development of management plans that include the long‐term monitoring of all MPAs, and the need for a thorough risk assessment process to be conducted before the establishment of an MPA. The issues raised in this paper should be relevant to the establishment of MPAs in an international context.  相似文献

Since the 1980s, there have been continuous increases in the coverage of marine protected areas (MPAs) in China, and a total of 158 MPAs have been declared. The MPA system in China is characterized by (1) decentralised designation and management with reduced control from the central government; (2) a dominance of de jure fully protected MPAs that are often implemented as de facto multiple-use areas; and (3) a lack of objective evaluation processes. To improve China's MPA system requires an appropriate integration of fully protected and multiple-use MPAs, and an approach that balances the advantages of top-down and bottom-up approaches.  相似文献

The introduction of marine protected areas (MPAs) in Australia has resulted in an increase in the number and total area of ‘no-take’ zones. The resulting closures impact all forms of commercial and recreational fishing in and around them despite international recognition indicating that Australian fisheries were already well managed according to ecological sustainable development guidelines. Furthermore, it is recognised within Australia that most MPAs are not designed to provide protection from the full suite of known threats that can affect biodiversity and long-term ecosystem viability. By directing MPA management disproportionately towards comprehensive no-take zones that affect fishing practices that are already required by state and federal legislation to adhere to sustainability requirements, the suite of threats affecting both protected and unprotected areas can be left inadequately and/or inappropriately managed. It is shown in this paper that the modified definition of the Precautionary Principle, which was developed specifically for the MPA process in Australia, is not in keeping with accepted international definitions and guidelines for the use of precaution. It is argued that the development of a definition of precaution to justify a predetermined output (MPAs) devalues the sound use of scientific principles and diminishes the conservation outcome. Furthermore, by distracting efforts from determining and managing the full suite of recognised threats, the value of what protection is provided in Australia's marine protected areas is eroded further.  相似文献

Various approaches have been used to establish marine protected areas (MPAs) in different countries. In this paper we compare and review three processes to establish MPAs within the United States and Australia. These two countries share many similarities in their cultures, but their approaches to managing marine resources differ considerably. Each of these efforts to establish or review MPAs was motivated by concern about declines of targeted marine species or habitats. However, the government actions varied because of differences in governance, planning process including public input, and the role of science. Comparing these processes highlights effective approaches for protecting marine ecosystems and gaining public support.  相似文献

No-take marine protected areas (MPAs), where all fishing is prohibited, have been shown to provide benefits that include greater productivity of fish stocks due to increased densities, average sizes, and reproductive output. A critical component of this success is the effective management of MPAs to ensure that only those activities deemed permissible, are allowed to occur. As of 2008, 161 MPAs had been designated on the Pacific coast of Canada by federal, provincial or municipal authorities. The objective of this study was to discover how many of these MPAs are intended to provide full protection to habitats and species from commercial fishing and whether management measures were put in place to actualize this conservation intent. The comprehensive spatial dataset was built illustrating commercial fisheries closures and this was overlaid with MPA locations in a GIS. The majority of MPAs were designated as IUCN Strict Nature Reserve (Type Ia), Wilderness Area (Type Ib), and National Park (Type II) marine reserves, which are intended to be free from exploitation. It was found that 160 of the 161 MPAs are open to some commercial harvesting within their bounds. One small municipal MPA and portions of three other MPAs are not open to commercial harvesting. The incongruence between management intent and fisheries permitted suggests a management failure between designation of MPAs and implementation of fisheries management regulations.  相似文献

In 1999 the Marine and Marine Industries Council was established by the Tasmanian (Australia) State Government and in 2001 a Tasmanian Marine Protected Area Strategy was launched. The aims of this paper are to: investigate the views, perceptions and attitudes of commercial fishers towards this Strategy and to identify the key issues that influence fisher support or opposition to marine protected areas (MPAs). Fifty-one structured interviews with license supervisors of commercial abalone, rock lobster and scalefish fishers were conducted. Fishers stated that they would conditionally support MPAs if they sustained or increased fish populations, supported research, allowed fishing in multiple use areas, and if multiple use areas contained small ‘no-take’ zones. Fishers were concerned about the ability of the government to provide adequate marine protected area monitoring and compliance and were critical of the public consultation process that accompanied the development of the Strategy. Concern was expressed regarding the potential negative impact of additional MPAs in terms of resource sustainability and the long-term economic viability of the fishery.  相似文献

Marine protected areas (MPAs) have become a common conservation and management tool for reducing exploitation from the commercial and recreational fisheries sectors. However, the recreational fisheries sector has the potential to be compatible with no-take MPAs when catch-and-release angling is practiced because, in theory, no fish are actually harvested. This presumes that the effects of catch-and-release angling and related activities do not cause appreciable declines in fish populations as a result of direct mortality, sub-lethal effects, or indirect effects on fish habitats, or other problems contrary to the goal of a given MPA. Here, we explore the idea that recreational catch-and-release angling may be compatible with some no-take MPAs provided there are no substantive negative ecological consequences. We argue that it is not currently possible to answer definitively the question of whether recreational catch-and-release fisheries can be compatible with no-take MPAs. Mortality rates of released fish vary extensively (between zero and near 100%) and are influenced by a number of factors including environmental conditions, fishing gear, angler behavior, and species-specific characteristics. Nevertheless, research in the field of catch-and-release is beginning to show that certain handling techniques can significantly reduce post-release mortality in fish. With appropriate regulation and angler education, catch-and-release could help enhance conservation and management goals associated with MPAs while maintaining public support and providing alternative tourism-based revenues for displaced fishers. Until sufficient data are available, research should focus on contrasting the fish community characteristics in regions with no fishing and those that permit catch-and-release fishing (i.e., opportunistic observations and controlled manipulations) as well as population-level mathematical modeling to assess the effects of angling on long-term population viability and ecosystem dynamics. Additional efforts should focus on education and outreach that provide anglers and fishing guides with the best available information to reduce catch-and-release mortality, sublethal angling-induced impairments, and broader effects on aquatic environments.  相似文献

Marine protected areas (MPAs) are aimed at managing and protecting marine environments. Their design, however, often disregards both a thorough knowledge of the distribution of habitats and assemblages and the use of proper experimental evaluations of the efficacy of MPAs by comparing protected vs. unprotected zones. About 200 MPAs have been recently instituted in the Mediterranean area, but the evidence of their efficacy is scant. The MPA of Torre Guaceto (Southern Adriatic Sea, Italy) is one of the rare cases of effective protection enforcement. The reserve was instituted more than 10 years ago, a period currently considered as sufficient to show responses by organisms to protection. The MPA is divided into a C zone, the general reserve, where many activities are permitted, a B zone, the partial reserve where restrictions increase and two A zones, the integral reserve where access is prohibited. The goals of the paper were to map the distribution of benthic assemblages to assess if they were properly represented in the differently protected zones, and to test the efficacy of protection by quantifying possible differences between the assemblages in two control areas and in the two A zones, where human impact is completely excluded. The analysis of habitat and assemblage distribution within the MPA showed that the zones with total protection do not include most valuable environmental types. Most of the considered variables (i.e. cover of substratum, number of taxa, and average abundance of the most common taxa) were not significantly different in and out of the A zones, at each time of sampling. Results, however, suggested a possible effect of protection in modifying patterns of abundance of sponges under Cystoseira canopy (more abundant in the fully protected zone). In the subtidal habitat, differences were found in the structure of the whole assemblage and in the abundance of encrusting coralline red algae (more abundant outside the fully protected area). Notwithstanding the correct general methodology employed in the study, a lack of statistical power could have a role in preventing the detection of ecologically relevant effects of protection. In some instances, data pooling allowed a discrimination between cases where there was clearly no effect of protection and cases where there might be. On this basis, the optimization of this experimental design should be considered in further studies. In any case, if the goals of MPAs have not been clearly stated, efficacy of protection might prove very difficult to test even with the use of sound experimental designs.  相似文献

It has been proposed that the elkhorn coral Acropora palmata is genetically separated into two distinct provinces in the Caribbean, an eastern and a western population admixing in Western Puerto Rico and around the Mona Passage. In this study, the genetic structure of A. palmata sampled at 11 Puerto Rican localities and localities from Curaçao, the Bahamas and Guadeloupe were examined. Analyses using five microsatellite markers showed that 75% of sampled colonies had unique genotypes, the rest being clone mates. Genetic diversity among genets was high (HE = 0.761) and consistent across localities (0.685–0.844). FST ranged from ?0.011 to 0.047, supporting low but significant genetic differentiation between localities within the previously reported eastern and western genetic provinces. Plots of genetic per geographic distances and significant Mantel tests supported isolation‐by‐distance (IBD) within Puerto Rico. Analysis with the software STRUCTURE favored a scenario with weak differentiation between two populations, assigning Eastern Puerto Rican locations (Fajardo and Culebra), Guadeloupe and Curaçao to the Caribbean eastern population and Western Puerto Rican locations (west of Vega Baja and Ponce), Mona and the Bahamas to the Caribbean western population. Vieques and San Juan area harbored admixed profiles. Standardized FST per 1000 km unit further supported higher differentiation between localities belonging to different STRUCTURE populations, with IBD being stronger within Puerto Rico than on larger regional scales. This stronger genetic transition seems to separate localities between putative eastern and western provinces in the Eastern Puerto Rican region, but not around the Mona Passage.  相似文献

Various international treaty bodies and non-governmental organisations continuously urge States to establish a network of Marine Protected Areas (MPAs) in areas beyond the limits of national jurisdiction (ABNJ). Although this goal is far from being reached, the OSPAR Convention may serve as an example illustrating the efforts made on a regional level for the North-East Atlantic. However, these efforts to effectively protect the marine environment are subject to limitations under the Convention on the Law of the Sea (UNCLOS). Likewise, the OSPAR Convention itself restricts the scope of such protected areas. The OSPAR Convention does not adequately cover all human uses of the oceans that may interfere with a protected area, and it lacks opportunities for internationalised enforcement measures. Consequently, the responsibility for effective conservation measures under the OSPAR model ultimately remains with individual Contracting Parties, i.e. their commitment to set stricter standards and to agree on their enforcement. Nevertheless, ‘soft’ obligations such as reporting duties are suitable for collecting data on the need for protection and utilisation of the MPAs. Additionally, cooperation with regional fisheries management bodies allows for better protection of the living resources in these areas. Finally, OSPAR MPAs can draw attention to particularly vulnerable ecosystems and promote conservation standards and measures such as those developed under the auspices of the FAO.  相似文献

Regional efforts have increased the number and amount of marine protected areas (MPAs) in the Caribbean, yet few studies have examined how these MPAs are progressing toward their goals and objectives. Using social and ecological data from a rapid assessment of 31 MPAs and their associated human communities in the wider Caribbean, this study investigates (1) the stated social and ecological objectives of MPAs; (2) the extent to which MPAs are making progress toward their stated social and ecological objectives; and (3) tradeoffs in progress toward social and ecological objectives. Findings indicate that Caribbean MPAs have multiple objectives related to both social and ecological conditions, and that most MPAs are making at least some progress towards achieving these objectives. Those MPAs with stated objectives to promote education and serve as a model for other MPAs seem to be making good progress on these objectives, while those with the objective of reducing conflict are not. Where MPAs are not meeting their goals and objectives, planners and managers should consider reallocating human and financial resources to address deficiencies and re-evaluating existing goals and objectives. It is important to consider how existing marine protected areas are performing as efforts in the Caribbean region and elsewhere continue to promote the establishment of new MPAs.  相似文献

In Belgium a long process (1999–2005) led to the designation of several marine protected areas (MPAs). In order to analyse the designation process, the ‘policy arrangement approach’ was used as an analytical tool. Attention was given to four dimensions (actors and coalitions, arguments, rules and resources). Particular attention was paid to the switch from an authoritative to a more deliberated policy style in reaction to conflicts with stakeholders. This switch in policy style contributed to a successful legal designation, but does not guarantee the best protection of marine biodiversity. This case study linked science (setting ecological goals) to policy (analysis of a policy process) and led to some more general conclusions on the designation of MPAs and the role of participation in this process.  相似文献

Historically, martial law in Taiwan severely restricted access to and use of coastal areas. Since the martial law was lifted in 1987, the government has permitted more than 80 development projects in coastal areas throughout Taiwan. However, rapid growth and overexploitation have led to significant degradation of oceanic and coastal environments. To protect and sustain marine ecosystem functions, species, and habitats, proactive conservation measures are needed. One of the most effective measures is the establishment of marine protected areas (MPAs). In this paper, we introduce the current situation of protected areas in Taiwan. We then discuss the general concepts of MPAs, describe the characteristics of Chinwan in the Penghu archipelago, and conclude with lessons learned from the attempt to establish an MPA at Chinwan.  相似文献

The Northern Gulf of California is an area important for small-scale fisheries in terms of economic activity and food security, but widespread non-compliance with fisheries regulations impedes effective management of resources and conservation efforts. Where a previous study evaluated quantitatively a theoretical situation in which all regulations are perfectly followed, this article compares a suite of recently proposed ecosystem-based management (EBM) policies against the expected benefits of full enforcement of current regulations. Policies evaluated include no-take marine protected areas (MPAs), breeding period closures, changes in hook size and fishing effort, and gear-specific spatial closures. No-take MPAs yield ecological benefits over a wide range of MPA sizes and characteristics, but do not increase overall catch. Seasonal closures are effective at reducing overfishing for the depleted leopard grouper (Mycteroperca rosacea); changing the hook size of artisanal longlines does not increase catch of either the target species or the assemblage, and gear-specific fishery closures for crab traps near Puerto Peñasco are effective at reducing overfishing of blue crab (Callinectes bellicosus and C. arcuatus). In general, full enforcement of existing regulations outperforms these EBM policies in terms of conservation benefits, but it may be less palatable to stakeholders as it requires major reductions in catch.  相似文献

The Belgian MPA designation process started in 1999, a journey that was characterized by several conflicts related to the multi-level government system in Belgium and obstacles, e.g. the de-designation of the Special Area of Conservation (SAC) 'Vlakte van de Raan' in 2008. On the other hand a number of successful events could be noted as well, e.g. the designation of three Special Protection Areas (SPAs) in 2005 in front of the three marine harbors, and the extension of the SAC 'Trapegeer-Stroombank' (designated in 2005) to an area >30% of the BPNS surface in 2012 (now renamed to SAC 'Vlaamse Banken'). The most important aspects that contributed to the successful designation of these MPAs in the BPNS were (1) the appointment of a minister of the North Sea in 2003 (and 2011), who was dedicated and specifically mandated to coordinate all federal North Sea matters (thus excluding fisheries); (2) the growing awareness of the need for nature conservation through different EU Directives (e.g. Marine Strategy Framework Directive (MSFD)); and (3) the level of stakeholder and public involvement, especially focusing on transparency throughout the process.  相似文献

The 1992 Convention on Biological Diversity has set ambitious targets for the establishment and management of protected areas. For the oceans, the overall aim is to establish, by 2012, an effectively managed, representative, global system of marine protected areas (MPAs) covering 10% of all marine ecological regions, comprising both multiple use areas and strictly protected areas. An analysis of data for three countries in Eastern Africa, where considerable efforts to promote MPAs by many agencies have been made over the past decade, shows that rapid progress has been made towards achieving this target. Since the first MPAs were established in the 1960s and 1970s, 8.7% of the continental shelf in Kenya, 8.1% in Tanzania and 4.0% in Mozambique has been designated, with the size of recently protected sites markedly larger than earlier sites. Commitments to expand the MPA networks in these countries would, if implemented, largely achieve the 10% coverage target. The location of existing marine protected areas shows good correlation with known sites of high species diversity; and coral reefs and Important Bird Areas are well represented. Management effectiveness of MPAs is also improving. However, there are major constraints to meeting the MPA target in these countries. Many habitats and species are not yet fully represented, the area closed to fishing is less than the recommended 20–30%, and capacity building is needed to improve many aspects of management. Furthermore, despite considerable investment in monitoring of coral reefs and other coastal habitats, the data available do not show clearly whether biodiversity and socio-economic objectives are being met. Although East African countries need to be congratulated for their vision, the results thus far indicate the urgency of both improving monitoring systems for measuring progress towards the targets, and also taking further steps to expand and improve management of existing MPAs.  相似文献

According to the United Nations (UN) Millennium Ecosystem Assessment, there has been a dramatic decline in global biodiversity. The UN has made a global appeal for all countries to mitigate their impact on the environment. Marine environmental protection is one of the most critical and urgent issues in the world and many countries have commenced establishing marine protected areas (MPAs) by implementing ecosystem-based management (EBM) concepts. MPA planning has been considered one of the simplest and most effective methods to protect marine environments. Taiwan has recently developed policies that have focused on its marine environment, and there are plans to increase the size of Taiwan׳s MPAs to 20% of its total ocean territory by 2020, thereby achieving a sustainable ocean. To achieve this goal, the government must address specific difficulties associated with the location of MPAs and relevant zoning strategies. This study establishes MPA protection principles and a zoning framework for MPAs in Taiwan by using Gueishan Island in Yilan County as a case study site to examine specific zoning strategies. The protection of 3 objectives (hydrothermal vents, cetacean, and fisheries resources) is discussed in this paper. Multi-criteria spatial analysis and a geographic information system are applied to identify the most crucial area to protect. To understand the stakeholders׳ opinions and concerns regarding the proposed zoning framework, this research conducted in-depth interviews with experts and stakeholders. MPAs zoning strategies are formulated at the conclusion of this study that could assist in protecting critical marine resources and avoiding conflicts among various usages of the marine area.  相似文献

Many conservationists and local governments in the Philippines (and other tropical countries) have attempted to link marine protected areas (MPAs) with dive tourism, arguing that the user fees generated by dive tourism can potentially generate satisfactory outcomes for all stakeholders. In this paper, an account of the relationship between MPAs, dive tourism and small-scale fisheries in the Calamianes Islands, Philippines, is presented. It is argued that although the assumed harmonious relationship between marine conservation and dive tourism may work in theory, in practice different understandings of MPAs can create conflict.  相似文献

In the North-east Atlantic Ocean there are 550 inshore and offshore MPAs established to accomplish a high diversity of objectives, which can be classified into 24 different types of MPA designations. Only 153 of these MPAs have a management plan (MgP) --the basic tool required for an effective management. Amongst these, only 66 are actually managed, i.e. they have the staff and resources required to operate the plan. A common characteristic of these MPAs is the lack of standardized indicators of their performance. In order to address this issue, an alternative approach was developed based on the assessment of management performance using the expert knowledge and perceptions of managers operating MPAs, a universal source of information that could allow overcoming the usual gaps due to the restrictions in coverage of scientific monitoring and assessments. MgPs showed differences among countries but were homogeneous within each country, reflecting the usual top-down approach in the establishment of MPAs. Compliance with the qualitative objectives present in MgPs was higher than compliance with quantitative ones (87% versus 50%), and the MPAs that most successfully achieved their objectives were those with regular monitoring. This analysis also shows that beyond these objectives, the establishment of an MPA and the activities developed as a consequence of its creation have a positive socio-economic impact on the local human community.  相似文献

Marine protected areas (MPAs) are increasingly being established to protect and rebuild coastal and marine ecosystems. However, while the high seas are increasingly subject to exploitation, globally few MPAs exist in areas beyond national jurisdiction. In 2010 a substantial step forward was made in the protection of high seas ecosystems with 286,200 km2 of the North-East Atlantic established as six MPAs. Here a summary is presented of how the world's first network of high seas marine protected areas was created under the OSPAR Convention, the main challenges and a series of key lessons learned, aiming to highlight approaches that also may be effective for similar efforts in the future. It is concluded that the designation of these six MPAs is just the start of the process and to achieve ecological coherence and representativity in the North-East Atlantic, the network will have to be complemented over time by additional MPA sites.  相似文献
