Download or read book Sustaining Marine Fisheries written by National Research Council and published by National Academies Press. This book was released on 1999-03-19 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.

Download or read book Effects of Trawling and Dredging on Seafloor Habitat written by National Research Council and published by National Academies Press. This book was released on 2002-08-09 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concerns over the potential ecological effects of fishing have increased with the expansion of fisheries throughout the marine waters of the United States. Effects of Trawling and Dredging on Seafloor Habitat describes how assessment of fishing impacts depends on gear type, number and location of bottom tows, and the physical and biological characteristics of seafloor habitats. Many experimental studies have documented acute, gear-specific effects of trawling and dredging on various types of habitat. These studies indicate that low mobility, long-lived species are more vulnerable to towed fishing gear than short-lived species in areas where the seabed is often disturbed by natural phenomena. Trawling and dredging may also change the composition and productivity of fish communities dependent on seafloor habitats for food and refuge. The scale of these impacts depends on the level of fishing effort. This volume presents color maps of fishing effort for all regions with significant bottom trawl or dredge fisheries-the first time that such data has been assembled and analyzed for the entire nation.

Download or read book A Meeting of Land and Sea written by David R. Foster and published by Yale University Press. This book was released on 2017-01-01 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: An eminent ecologist shows how an iconic New England island has been shaped by nature and human history, and how its beloved landscape can be protected Full of surprises, bedecked with gorgeous photographs and maps, and supported by unprecedented historical and ecological research, this book awakens a new perspective on the renowned New England island Martha's Vineyard. David Foster explores the powerful natural and cultural forces that have shaped the storied island to arrive at a new interpretation of the land today and a well-informed guide to its conservation in the future. Two decades of research by Foster and his colleagues at the Harvard Forest encompass the native people and prehistory of the Vineyard, climate change and coastal dynamics, colonial farming and modern tourism, as well as land planning and conservation efforts. Each of these has helped shape the island of today, and each also illuminates possibilities for future caretakers of the island's ecology. Foster affirms that Martha's Vineyard is far more than just a haven for celebrities, presidents, and moguls; it is a special place with a remarkable history and a population with a proud legacy of caring for the land and its future.
