Biologists with the National Oceanic and Atmospheric Administration (NOAA) have responded to six stranded dolphins since June 20 and while itâs too soon to directly link those sick and dead dolphins to red tide, they say thatâs much higher than average. Back in 2018 and 2019, NOAA found 180 of Floridaâs West Coast dolphins were killed by the toxic algae blooms.
