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.

Congress has promoted fisheries science for over a century and its involvement in fisheries management took a great leap forward with passage of the Fisheries Conservation and Management Act of 1976. In the past decade, Congress has requested advice from the National Research Council (NRC) on both national issues (e.g., individual fishing quotas and community development quotas) and the assessments related to specific fisheries (Northeast groundfish). This report was produced, in part, in response to another congressional request, this time related to the assessments of the summer flounder stocks along the East Coast of the United States. Following the initial request, the NRC, National Marine Fisheries Service (NMFS), and congressional staff agreed to broaden the study into a more comprehensive review of marine fisheries data collection, management, and use.

The present book is in three parts. The first one deals with general information on world sea fisheries such as major fishing areas, various resources, origins of marine fishing infrastructure and facilities needed in fishing ports, tools for development, adverse impact of certain modern fishing gears, sustainable mariculture and outlook of the future. The second part incorporates research methods on marine fish resources such as major projects and programmes needed, the data bases required, methods of their collection, population dynamics, estimation of stock size, mortalities and maximum sustainable yield, bioeconomic consideration, methods and laws for judicious management. In the third part the progress of research, development and education in India are outlined, including prominent findings so far on important resources and subjects, the endangered groups and ecosystems, marketing, exports, economy, functioning of laws and regulations, planning for the future, etc., etc. Lavishly illustrated and much more needed this book is useful for students, teachers as well as researchers.
