The Florida Fish and Wildlife Conservation Commission is reporting an outbreak of Trichodesmium, sometimes called a brown tide, in waters offshore of Manatee County.
It is a separate species but similar to the well-documented Karenia brevis, a photosynthetic organism responsible for the persistent red tide hitting Manatee and other nearby counties along 130 miles of coastline. Concerns are now being raised that if the two blooms merge, it could essentially deepen an ongoing red tide.
