A 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 concentrations in two samples collected from Sarasota County, low concentrations in two samples collected from Charlotte County, very low to medium concentrations in eight samples collected from or offshore of Lee County, background to medium concentrations in 20 samples collected from Collier County, and very low concentrations in three samples collected from or offshore of Monroe County.
In Northwest Florida over the past week, K. brevis was observed at background concentrations in one sample collected from Bay County and two samples collected from Gulf County.
Additional samples collected throughout Florida over the past week did not contain K. brevis.
Over the past week, fish kills were reported in the following Southwest Florida counties: Sarasota (4/9 at Nokomis and Venice North Jetty), Lee (4/7 – 4/11 at Bonita Beach, 4/6 and 4/9 at Gasparilla Island, 4/11 at Lighthouse Beach, 4/9 at Little Estero Island Beach, 4/8 – 4/11 at Lovers Key, 4/9 – 4/10 at Newton Park), Collier (4/7 – 4/10 at Barefoot Beach, 4/8 at Beach Central, Big Hickory Pass, Doctor’s Pass, and Vina Miramar Beach, 4/9 at Residents Beach, 4/9 – 4/11 at Vanderbilt Beach) and Monroe (4/4 in Florida Bay near Pavilion Island). Respiratory irritation was reported over the past week in Lee (4/5 and 4/7 – 4/11 at Bonita Beach, 4/10 – 4/11 at Lovers Key, 4/10 at Newton Park) and Collier (4/7 – 4/10 at Barefoot Beach, 4/9 at Seagate and South Marco Beach, 4/9 – 4/11 at Vanderbilt Beach) counties.
Forecasts by the USF-FWC Collaboration for Prediction of Red Tides for Pinellas to northern Monroe counties predict net offshore transport of surface waters and southern, onshore transport of subsurface waters over the next three days.
Hope this water issue will go away soon.
