Satellite imagery over the past week has shown low concentrations of chlorophyll off the coast of Southwest Florida. Karenia brevis and/or other algal species may be contributing to the chlorophyll concentrations.

No Karenia brevis was detected in FWC samples in Southwest Florida. The Clinic for the Rehabilitation of Wildlife (CROW) on Sanibel received 29 birds with toxicosis symptoms (from red tide or blue-green algae) from 11/21/21 - 11/28/21.
