Researchers Trying to Find Ways to Kill Blue-Green Algae as it Begins to Reappear

Blue-green algae is showing up again in the Caloosahatchee River. There’s enough of it that the Florida Department of Health has put up signs, warning people not to swim.

Calusa Waterkeeper John Cassani said he expected to see algae blooms again when the Army Corps of Engineers released more water down the river from Lake Okeechobee.

Cassani took video Tuesday of fish swimming through a patch of algae.

“Those were two exotic species of fish that were trying to sort of opportunistically feed on the algae at the surface,” said Cassani.

Cassani said, with blooms already present on Lake Okeechobee, he’s worried the water coming downstream will cause it to spread.

“That’s what’s on everyone’s mind is how do we prevent this from happening?” said Cassani.
