Southwest Region: A bloom of the Florida red tide organism, Karenia brevis, is currently present along the southwest coast in Lee and Collier counties. Background to medium concentrations were detected in Pine Island Sound, however the presence of K. brevis is patchy and not the cause of cloudy water conditions currently being reported in this area. Alongshore in Lee County (between southern Sanibel Island and Lovers Key) concentrations ranged from not present to low. In Collier County medium and high concentrations were detected at Lely Barefoot Beach and Clam Pass respectively. Offshore samples collected this week between Sanibel Island and Naples contained the marine cyanobacteria Trichodesmium and K. brevis concentrations ranging from not present to medium. Multiple reports of fish kills and respiratory irritation have been received from Ft. Myers Beach to Naples. Discolored water is possible in Manatee County due to a non-toxic diatom bloom in the area.
