Scientists hoping to provide a genetic lifeline to Florida’s ailing reef are removing hundreds of colonies of healthy coral off Miami, hoping to outpace a wave of lethal bleaching spreading from the Florida Keys.

About 400 colonies have been moved by University of Miami Rosenstiel teams in the last week to tanks at the school’s fish hatchery on Virginia Key — but space is quickly running out.

“You have to realize that we’re only rescuing a fraction of our stocks where we’re saving key genotypes,” said marine biologist Diego Lirman, whose Rescue A Reef lab oversees two nurseries off Key Biscayne. “We’re leaving out there thousands of corals that we have nowhere to put.”

At May’s Nursery in Havana, algae is beginning to take over a nearby pond. Not only do farmers use the pond to water over 400 different species of plants, but scientists have found the pond feeds directly into the Gulf of Mexico and imposes a serious threat to the state’s ecosystem.

Dan Levy is the founder of AECOM’s algae practice team and is partnering with the Northwest Florida Water Management District to clean and collect algae from Northwest Florida water bodies.

“Unfortunately, when an abundance of nutrients get in our waterways, we end up forming harmful algal blooms,” said Levy.

Benson scooped up the fish and handed it off to the scientists at Bonefish & Tarpon Trust for further study. The tiny puffer was hardly the last dead fish he would see across the Florida Keys last month.
