East Coast
Karenia brevis, the Florida red tide organism, was not detected in water samples collected this week in the Indian River (Brevard and Indian River counties).
Discolored water that has been reported in the Indian and Banana Rivers (Brevard County) for more than two months (first reported 05/13/2011) is from an ongoing bloom of a non-toxic alga. In other areas of the Indian River (Indian River Aquatic Preserve, Indian River County), there have been reports of discolored water due to a bloom of the dinoflagellate Takayama tasmanica (first reported on 07/15/2011). Fish kills have recently co-occurred with algal blooms throughout the Indian River Lagoon.
