Available in PDF, EPUB and Kindle. Book excerpt: Although the ocean-and the resources within-seem limitless, there is clear evidence that human impacts such as overfishing, habitat destruction, and pollution disrupt marine ecosystems and threaten the long-term productivity of the seas. Declining yields in many fisheries and decay of treasured marine habitats, such as coral reefs, has heightened interest in establishing a comprehensive system of marine protected areas (MPAs)-areas designated for special protection to enhance the management of marine resources. Therefore, there is an urgent need to evaluate how MPAs can be employed in the United States and internationally as tools to support specific conservation needs of marine and coastal waters. Marine Protected Areas compares conventional management of marine resources with proposals to augment these management strategies with a system of protected areas. The volume argues that implementation of MPAs should be incremental and adaptive, through the design of areas not only to conserve resources, but also to help us learn how to manage marine species more effectively.

This book was released on 1999-03-05 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fluctuations and declines in marine fish populations have caused growing concern among marine scientists, fisheries managers, commercial and recreational fishers, and the public. Sustaining Marine Fisheries explores the nature of marine ecosystems and the complex interacting factors that shape their productivity. The book documents the condition of marine fisheries today, highlighting species and geographic areas that are under particular stress. Challenges to achieving sustainability are discussed, and shortcomings of existing fisheries management and regulation are examined. The volume calls for fisheries management to adopt a broader ecosystem perspective that encompasses all relevant environmental and human influences. Sustaining Marine Fisheries offers new approaches to building workable fisheries management institutions, improving scientific data, and developing management tools. The book recommends ways to change current practices that encourage overexploitation of fish resources. It will be of special interest to marine policymakers and ecologists, fisheries regulators and managers, fisheries scientists and marine ecologists, fishers, and concerned individuals.

Available in PDF, EPUB and Kindle. Book excerpt: This book really began in 1980 with our first microcomputer, an Apple II +. The great value of the Apple II + was that we could take the computer programs we had been building on mainframe and mini-computers, and make them available to the many fisheries biologists who also had Apple II + 's. About 6 months after we got our first Apple, John Glaister came through Vancouver and saw what we were doing and realized that his agency (New South Wales State Fisheries) had the same equipment and could run the same programs. John organized a training course in Australia where we showed about 25 Australian fisheries biologists how to use microcomputers to do many standard fisheries analyses. In the process of organizing this and sub sequent courses we developed a series of lecture notes. Over the last 10 years these notes have evolved into the chapters of this book.

Available in PDF, EPUB and Kindle. Book excerpt: "This document has been developed to provide information and guidance on the use of marine protected areas (MPAs) in the context of fisheries. As MPA implementation moves ahead in the arena of marine biodiversity conservation, many people feel that the fisheries aspects are not fully understood nor always appropriately taken into account, and that guidance specific to this sector is needed. These Guidelines look specifically at fisheries features of MPAs, but also address the interface between fisheries management and biodiversity conservation and provide support for MPAs with multiple objectives. The Guidelines are divided into two sections: the first discusses definitions and context, and provides background information on fisheries management, the ecosystem approach to fisheries (EAF) and MPAs as a tool for fisheries management, including socio-economic and biological impacts. The second section considers the planning and implementing of MPAs including the institutional, legal and policy context, the planning process and actual implementation considerations. Conclusions and future directions are offered in the last chapter of this section, while a selection of annexes offers in-depth information on a few key issues. The document highlights the need for increased coordination across sectors and agencies/departments. Integration of diverse interests and viewpoints is required if we are to successfully manage our oceans and their resources for future generations. As with all fisheries management, good governance -- including adequate stakeholder participation -- is key to successful and equitable management outcomes."--P. [4] of cover.

Download or read book Utility and Implications of No-take Marine Reserves in Fishery Management Strategies written by Carey R. McGilliard and published by . This book was released on 2012 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work explores (1) the potential for using marine reserves to manage data-poor fish populations, (2) the potential for marine reserves to influence the performance of commonly used stock assessment approaches relative to alternative approaches that explicitly account for a marine reserve, and (3) hypotheses about the role of older females to population persistence and arguments that marine reserves are needed to maintain this role. In Chapter 1, the potential use of the ratio of the density of fish outside a marine reserve to that inside the reserve in a fishery management control rule (DRCR) is evaluated by Management Strategy Evaluation. The cumulative catch under the optimal DRCR was 90% of the cumulative catch from an optimal constant effort rule (CER). A small range of parameter values for the DRCR produced 75% or more of the cumulative catch produced from optimal CERs for a variety of assumptions about biology and initial stock status. The optimal DRCR was most sensitive to movement patterns of larvae and adults and survey variability. In Chapter 2, a simulation model was used to analyze the ability of several stock assessment approaches to estimate current biomass after the implementation of a marine reserve. Results show that assessing populations as a single stock without accounting for a no-take marine reserve and performing separate assessments for fished and protected areas can lead to severely biased estimates of biomass. An assessment approach which explicitly accounted for fish movement was robust to uncertainty in movement patterns. In Chapter 3, two popular hypotheses are modeled; one assumes that older mothers produce larger offspring capable of surviving longer starvation periods than offspring from younger mothers. The other modeled hypothesis is that mothers of different ages spawned in different times or locations. Recruitment variability was 55-65% lower than for control models in the absence of fishing and increased with increases in fishing mortality rates for both models. A marine reserve policy did not benefit measures of sustainability for either model.

Download or read book The Controversy over Marine Protected Areas written by Alex Caveen and published by Springer. This book was released on 2014-10-17 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a critical analysis of the concept of marine protected areas (MPAs) particularly as a tool for marine resource management. It explains the reasons for the extraordinary rise of MPAs to the top of the political agenda for marine policy, and evaluates the scientific credentials for the unprecedented popularity of this management option. The book reveals the role played by two policy networks – epistemic community and advocacy coalition – in promoting the notion of MPA, showing how advocacy for marine reserves by some scientists based on limited evidence of fisheries benefits has led to a blurring of the boundary between science and politics. Second, the study investigates whether the scientific consensus on MPAs has resulted in a publication bias, whereby pro-MPA articles are given preferential treatment by peer-reviewed academic journals, though it found only limited evidence of such a bias. Third, the project conducts a systematic review of the literature to determine the ecological effects of MPAs, and reaches the conclusion that there is little proof of a positive impact on finfish populations in temperate waters. Fourth, the study uses discourse analysis to trace the effects of a public campaigning policy network on marine conservation zones (MCZs) in England, which demonstrated that there was considerable confusion over the objectives that MCZs were being designated to achieve. The book’s conclusion is that the MPA issue shows the power of ideas in marine governance, but offers a caution that scientists who cross the line between science and politics risk exaggerating the benefits of MPAs by glossing over uncertainties in the data, which may antagonise the fishing industry, delay resolution of the MPA issue, and weaken public faith in marine science if and when the benefits of MCZs are subsequently seen to be limited.

Book excerpt: This is a new edition of the classic textbook on marine protected area (MPA) management in the tropics, originally produced as an output of the Bali World Parks Congress in 1982. Approaches to planning and managing MPAs have evolved considerably. Major advances include innovative financing mechanisms, partnerships with the private sector and NGOs, and collaborative management between government and coastal communities. These advances have brought new approaches for MPA establishment and management that are more participatory, involving communities through interaction and collaboration rather than prescription. With new case studies and illustrations, the guide comes in a water-resistant cover for field use. It is intended for those who plan individual and/or national MPA systems and gives philosophical context for MPAs along with some basic principles and approaches.

Available in PDF, EPUB and Kindle. Book excerpt: In the face of increasing anthropogenic threats to marine systems, marine reserves have become a popular tool to promote sustainable fisheries management and protect marine biodiversity. However, the governance structures that determine marine reserve success are not well understood. The response of resource users to reserve establishment, as well as the socioeconomic, institutional, and political contexts in which they occur, are rarely considered during reserve implementation. I use the Coupled Infrastructure Systems (CIS) framework to better understand the interdependencies between social, economic, natural, and institutional processes affecting reserve implementation and performance efficacy in the Gulf of California, Mexico. I used a combination of interviews, qualitative case study comparisons, and systematic conservation planning tools to evaluate the role of different infrastructures, institutions, and governance for marine reserve efficacy in the Gulf of California, Mexico. At a local scale, I assessed stakeholder perceptions, preferences, and knowledge on reserves in the Midriff Islands sub-region of the Gulf. My results show differences in fisher perceptions about the use of reserves for biodiversity conservation and fisheries management, misconceptions about their location, and non-compliance behavior problems. At the regional scale, I explored the trajectories of reserve implementation and performance. I show that capacity-building programs and effective collaboration between non-profit organizations, environmental, fisheries, and other government authorities are essential to coordinate efforts leading to the provisioning of infrastructure that enables effective marine reserves. Furthermore, these programs help facilitate the incorporation of fishers into diversified management and economic activities. Infrastructure provision tradeoffs should be carefully balanced for designing scientifically-sound reserves that can achieve fisheries recovery objectives and incorporating stakeholder engagement processes during the planning phase that allow fishers to include their preferences in a way that complements proposed reserve network solutions. Overall, my results highlight the importance of multiple infrastructures in understanding the dynamics of interacting action situations at various stages of marine reserve implementation and operation. I identify strengths and weaknesses within marine reserve systems that help understand what combinations of infrastructures can be influenced to increase marine reserve effectiveness and robustness to internal and external challenges, as well as delivering benefits for both nature and people.
