In this Monday, July 18, 2011 photo, a southern stingray swims near the shoreline on Vanderbilt Beach, in Naples, Fla. The Naples Daily News reports that an unusual arrival of offshore fish, some of them dead, littered the shoreline Monday in North Naples. The Florida Fish and Wildlife Conservation Commission is testing water samples and shark tissue to determine the cause of the dark water and fish kill. Scientists suspect low-dissolved oxygen, possibly as a result of a dying algae bloom, are killing the fish. The health department has not advised swimmers to stay out of the water.
