Red Tide report 7.22.11


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.
 
Northwest Coast
Karenia brevis, the Florida red tide organism, was not detected in water samples collected this week alongshore of Okaloosa County or offshore of Okaloosa and Taylor counties.
 
Southwest Coast
Karenia brevis, the Florida red tide organism, was not detected in water samples collected this week alongshore between Pinellas and Collier counties or offshore of Lee and Collier counties and the Florida Keys (Monroe County)
 
Discolored water reported alongshore of Collier County is from a mixed algal bloom that includes the dinoflagellate Takayama tuberculata and several species of diatoms.  Mortalities and morbidities of sharks, rays, various fish species, lobsters, crabs and other invertebrates were reported alongshore of Vanderbilt Beach south to Doctor’s Pass and inside of Clam Pass (Collier County) on 7/18 and 7/19.
 
Discolored water reported in Old Tampa Bay is from a bloom of the dinoflagellate Pyrodinium bahamense, which has bloomed in this same area from late spring to late summer in past years.  No effects have been reported from this bloom.
