A red tide event near San Diego, California

Researchers at Mote Marine Laboratory are launching a new study this week that will test whether filter-feeding animals and seaweeds can mitigate the effects of Florida red tide. Mote staff scientists Vince Lovko and Tracy Fanara are leading the new project, which will examine whether organisms can sift out the red tide-causing microscopic organism Karenia brevis and the toxins it produces. Red tide can kill fish and marine mammals and harm humans by causing respiratory irritation and neurotoxic shellfish poisoning. The National Oceanic and Atmospheric Administration estimates that harmful algae blooms like red tide cause $82 million in economic losses to the seafood, restaurant and tourism industries each year in the United States.
