Karenia brevis, the Florida red tide organism, was not detected in water samples collected this week alongshore of Pinellas, Hillsborough, Charlotte, Lee and Collier counties or offshore of Sarasota and Collier counties and the Florida Keys (Monroe County). Two samples (out of 28 total samples) collected alongshore of Sarasota County contained background concentrations of K. brevis and one sample collected alongshore of Manatee County contained very low concentrations of K. brevis.
FWRI is currently conducting a research cruise offshore of southwest Florida with data reported daily from the field. Only one sample collected offshore of Lee County has contained background concentrations of K. brevis (out of over 90 samples collected since Friday 10/15).
Discolored water with associated fish kills and a foul odor were reported this week in the area of Ft. Myers Beach south to Starling Avenue (Lee County) and is due to a bloom of the non-toxic dinoflagellate Peridinium quinquecorne
