Sommario/riassunto |
|
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 species-including marine mammals, seabirds, sea turtles, and sea grasses-either 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. |
