Dead Zones May Lead to Different Fisheries Management

摘要

A new approach to managing ocean fisheries by controlling nutrient runoff far upstream in watersheds has received new support from emerging evidence that resulting coastal low-oxygen dead zones,may reduce fish and shellfish harvests,said a Duke University marine scientist.Larry Crowder,a marine biology professor at Duke's Nicholas School of the Environment and Earth Sciences,recently discussed these potential long-range impacts of nutrient runoff from distant farm fields at a symposium during the American Association for the Advancement of Science's 2005 annual meeting.
