A patchy bloom of the Florida red tide organism, Karenia brevis, persists in Southwest Florida.
In Southwest Florida over the past week, K. brevis was observed at background to medium concentrations in 12 samples collected from Sarasota County, background to high concentrations in 11 samples collected from or offshore of Charlotte County, background to high concentrations in 22 samples collected from or offshore of Lee County, and background to high concentrations in four samples collected from or offshore of Collier County.
Background concentrations were observed in one sample collected offshore of Hernando County. Additional samples collected throughout Florida over the past week did not contain K. brevis.
