This book was released on 1998-03-13 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ocean harvests have plateaued worldwide and many important commercial stocks have been depleted. This has caused great concern among scientists, fishery managers, the fishing community, and the public. This book evaluates the major models used for estimating the size and structure of marine fish populations (stock assessments) and changes in populations over time. It demonstrates how problems that may occur in fisheries data--for example underreporting or changes in the likelihood that fish can be caught with a given type of gear--can seriously degrade the quality of stock assessments. The volume makes recommendations for means to improve stock assessments and their use in fishery management.

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 Striper Wars written by Dick Russell and published by Island Press. This book was released on 2013-02-22 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: When populations of striped bass began plummeting in the early 1980s, author and fisherman Dick Russell was there to lead an Atlantic coast conservation campaign that resulted in one of the most remarkable wildlife comebacks in the history of fisheries. As any avid fisherman will tell you, the striped bass has long been a favorite at the American dinner table; in fact, we've been feasting on the fish from the time of the Pilgrims. By 1980 that feasting had turned to overfishing by commercial fishing interests. Striper Wars is Dick Russell's inspiring account of the people and events responsible for the successful preservation of one of America's favorite fish and of what has happened since. Striper Wars is a tale replete with heroes--and some villains--as the struggle to save the striper migrated down the coast from Massachusetts to Maryland. Russell introduces us to a postman at arms against a burly trap-net fisherman, a renowned state governor caving to special interests, and a fishing-tackle maker fighting alongside marine biologists. And he describes how champions of this singular fish blocked power plants and New York's Westway Project that would otherwise compromise its habitat. Unfortunately, those who cheered the triumphant ending to the campaign, as the coastal states enacted measures that enabled the striped bass to make its comeback, have found the peace transitory--there is now a new enemy emerging on the front. In recent years a chronic bacterial disease has struck more than seventy percent of the striped bass population in the primary spawning waters of the Chesapeake Bay. Malnutrition seems to be a significant factor, brought on by the same overfishing that plagued the bass in the first battle--only this time, the overfishing is devastating menhaden, the silvery little fish upon which the bass feed. Lessons learned during the first conservation battle are being applied here, highlighting a need for a whole new ecosystem-based approach to conserving species. Only with constant vigilance by concerned citizens, Dick Russell reminds us, can environmental victories be sustained. This particular fish story is a personal one for him, and he follows the striper's saga today all the way to California, where the fish was introduced in 1879 and where agribusiness now threatens its future. For his conservation work during the 1980s Russell received a citizen's Chevron Conservation Award.
