Red Tide Status - Florida Southwest Coast April 16, 2021 Present Status: The red tide organism, Karenia brevis, persists in Southwest Florida. K. brevis was observed at background to medium concentrations in 20 samples collected from Sarasota County, background to high concentrations in seven samples collected from Charlotte County, background to very low concentrations in six samples collected from and offshore of Lee County, and background to medium concentrations in seven samples collected from Collier County. No samples were analyzed this week from Monroe County. A more detailed summary is provided in the table below. A fish kill suspected to be related to red tide was reported over the past week in Sarasota County. For more details, please visit: https://myfwc.com/research/saltwater/health/fish-kills-hotline/. Respiratory irritation was reported over the past week in Sarasota County (4/10 at Casperson Beach; 4/12 and 4/15 at Lido Key; 4/11-4/12 at Manasota Beach; 4/8 and 4/10-4/11 at Nokomis; 4/10-4/15 at Siesta Key; 4/8, 4/10, and 4/12 at Venice Beach; 4/8-4/12 and 4/15 at Venice North Jetty).
