The hordes of fish were killed by a red tide, a large "bloom" of toxic algae that appears on Florida's Gulf Coast about once a year. Experts say the bloom shouldn't be happening right now.

Red tide is officially impacting Pinellas County. Crews have picked up a total of 33.48 tons of dead fish and hauled them off to the county dump.

The toxic algae bloom has already been named as the killer or suspected killer of more than 100 manatees since the spring.

On a more helpful note, fish farts also are giving researchers and managers clues about fish distributions.
