The number of dead and dying fish washing up on Collier County beaches is declining. But hundreds of marine animals from crabs and lobsters to eels and nurse sharks were seen on beaches or swimming near the beach Monday and Tuesday. Experts think the fish kill was caused by an algae bloom which created a so called dead zone in the Gulf…an area with very little dissolved oxygen. WGCU’s John Davis spoke with Carli Segelson of the Florida Fish and Wildlife Research Institute which is monitoring the situation.
