Describes and evaluates the use of marine reserves as a fishery management tool, and concludes that efficacy of this strategy is evidenced by increases in affected fish stocks, increases in affected fishes' biomass, increased catches in areas close to reserve boundaries (known as "fishing-the-line"), inter alia

The world’s stocks of wild fish continue to decline, making the task of finding innovative, sustainable and socially acceptable methods of fisheries management more important than ever. Several new approaches from around the world have proved to be successful in stemming the decline whilst increasing fish catches, and under the editorship of McClanahan and Castilla this international team of authors have looked to these examples to provide the reader with carefully chosen case studies offering practical suggestions and solutions for problem fisheries elsewhere. Coverage includes: Community based fisheries Collaborative and co-operative fisheries management Coastal fisheries management The future for sustainable fisheries management Written by many of the world’s most experienced practitioners Fisheries Management: Progress toward sustainability is an important purchase for all fisheries scientists, managers and conservationists. All libraries in universities and research establishments where this area is studied and taught will find this book a valuable addition to their shelves.

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.

Building on work presented at the IUCN World Parks Congress (WPC) held in Australia in 2014, this document outlines experiences with aquatic protected areas (PAs), marine protected areas (MPAs) and protected areas in inland waters in the context of livelihoods and food security. It provides a general overview of MPAs and reports on their interface with livelihoods and food security, based on case studies in Africa, Asia, Latin America and Oceania. It also synthesizes the papers conclusions and discusses the observed outcomes of aquatic PAs, together with problems and solutions.

Since the industrial revolution, natural resource systems have rapidly modernized and globalized. Commercial fishing industries have expanded and optimized resource extraction but have often times exceeded sustainable levels of harvest. In the Pacific Northwestern United States, the commercial fishing industry is one of particular economic and cultural importance. Due to reduced yield of many native fish stocks, marine reserves have been implemented in Oregon's nearshore waters in an effort to conserve biodiversity. While spatial closures of marine reserves seek to preserve and stabilize Oregon's ocean ecosystems, adverse socioeconomic implications are inevitably created when profitable waters are set aside. A main challenge of marine policy is achieving conservation goals while simultaneously protecting and maintaining the socioeconomic livelihood of ocean users. As policy makers push for aggressive conservation policy, it is imperative to understand the ways in which different groups of stakeholders will be impacted by regulation. The objectives of this study were to (1) assess potential fishing displacement from marine reserve designation and identify internal and external socioeconomic factors explaining variability in fishing behavior, and (2) evaluate shifting familial succession patterns across fisheries and port groups within Oregon's nearshore fisheries. A mail survey dispersed to permit holders in Oregon's commercial Dungeness crab, salmon, and groundfish fisheries contained questions regarding spatial and temporal shifts in fishing behavior, operating expenditures, as well as demographic information. The first study objective was to assess impacts of marine reserve designation on the ways that fishing effort is exerted and how efforts differ between fishing communities and fleets in Oregon's nearshore environment over time. Quantitative and spatial measurements of fishing effort can help determine which areas are most heavily fished, which areas are collectively perceived to be the best and worst fishing grounds and how fisher's behaviors are responding to market, regulatory, ecological, and climatic variability. A repeated measures analysis of variance revealed that fishing effort was not reduced or displaced by marine reserve implementation, but rather driven by fishery closures resulting from low stock health linked to climatic variability. Linear mixed effects models revealed that large-scale fishing operations are more resilient and flexible to climatic, regulatory, economic, and ecological variability. The second study objective evaluated familial succession in Oregon's nearshore fisheries. Many rural industries, such as agriculture, timber and commercial fishing, are experiencing reduced youth recruitment and participation. Rural to urban migration patterns and large barriers to entry have been cited as reasons for the graying of Oregon's commercial fishing industry. It is important to understand which socioeconomic factors drive recruitment into the fishery in order to successfully manage and communicate with fishery participants. A binomial logistic regression model revealed that fishers with large-scale fishing operations are much more likely to participate in familial succession within the industry, compared to a fisher with a relatively small business. Chi-squared goodness of fit analyses indicated that in some regions along the coast, succession often mirrors the health and economic viability of a fishery and dynamics of local economies.

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.
