Thousands of fish dead in Florida Bay

Florida wildlife officials say thousands of fish that turned up dead this week in Florida Bay may be victims of a marine version of heat stroke.Everglades National Park chief of biological resources Dave Hallac says the number of dead fish was unusually large. Redfish, snook and other species were among the dead animals.The bay is a delicate ecosystem with vast flats only a few feet deep. As a result, water conditions can change rapidly with the weather - heat raising the water's salt content and killing sea grass, affecting other life.The park is still investigating possible causes of the deaths.The Miami HeraldAssociated Press - July 23, 2009 5:54 AM ET ST.
