FWRI (Fish and Wildlife Research Institute) reports that water samples collected alongshore between Pinellas
and Monroe counties contained no K. brevis. (www.floridamarine.org).
Monitoring data collected by the River, Estuary and Coastal Observing Network
(RECON) of Sanibel-Captiva Conservation Foundation (SCCF) indicated that over
the last week Chlorophyll concentrations ranged between 1.0 to 7.0 µg/L at Shell Point and were unavailable at Ft.
Myers. The DO concentration at Shell Point ranged from 5.6 to 7.0 mg/L (www.recon.sccf.org).
