FILE PHOTO - In this April 27, 2010 file photo, a shrimp boat is seen in the Gulf of Mexico near the Chandeleur Islands, off the Southeastern tip of Louisiana. Efforts to protect endangered sea turtles in the Gulf of Mexico have prompted strenuous complaints from the dwindling fleet of shrimpers blamed for drowning them in their nets, who say their own livelihoods are threatened. By next March the federal government wants about 2,435 shrimp boats, most run by mom-and-pop operations, to install turtle-saving gear in their nets to protect the turtles, whose survival has gained renewed concern after BP's catastrophic 2010 Gulf oil spill. The spill prompted closer study of turtle deaths, though scientists have concluded that most were due to drowning and not effects of the spill. (AP Photo/Gerald Herbert, file)
