Committee on Ecosystem Effects of Fishing: Phase II — Assessments of the Extent of Change and the Implications for Policy & Division on Earth and Life Studies 
Dynamic Changes in Marine Ecosystems [EPUB ebook] 
Fishing, Food Webs, and Future Options

поддержка

Recent scientific literature has raised many concerns about whether fisheries have caused more extensive changes to marine populations and ecosystems than previously realized or predicted. In many cases, stocks have been exploited far beyond management targets, and new analyses indicate that fishing has harmed other speciesincluding marine mammals, seabirds, sea turtles, and sea grasseseither directly through catch or habitat damage, or indirectly through changes in food-web interactions. At the request of the National Oceanic and Atmospheric Administration, the National Research Council conducted an independent study to weigh the collective evidence for fishery-induced changes to marine ecosystems and the implications of the findings for U.S. fisheries management. Dynamic Changes in Marine Ecosystems provides comprehensive information in regard to these findings.
