ORLANDO, Fla. (AP) Scores of dolphins have died along Floridas southwest coast due to the red tide bloom in the past year, federal researchers said.

Figures released by the National Oceanic and Atmospheric Administration showed 174 dolphins were stranded in a mass die-off between last July and last week.

Fish, sea turtles and manatees also have died from the red tide bloom, which has plagued the southwest Florida Gulf Coast since November 2017.
