Red tide increases around Tampa Bay
November 12, 2022 - According to the latest Florida Fish and Wildlife Commission (FWC) red tide update, toxic algal blooms have increased around Tampa Bay. Samples collected in Manatee County and the mouth of Tampa Bay now show medium concentrations of Karenia brevis - the organism that causes red tide - with low levels persisting off Bunces Pass. The FWC also reports fish kills and respiratory irritation due to high concentrations in Sarasota County. The red tide forecast map, created in conjunction with the University of South Florida College of Marine Science, predicts variable movement “with net southern transport in most areas over the next 3.5 days.”
