Red Tide Status (September 23, 2016)

A bloom of the red tide organism, Karenia brevis, has been observed in Southwest Florida along Manatee and Sarasota counties.

Karenia brevis was observed in Southwest Florida in background to very low concentrations in five samples collected from Pinellas County, background to high concentrations in forty-one samples collected from Manatee and Sarasota counties, background to very low concentrations in three samples collected from Charlotte County, background to low concentrations in five samples collected from Lee County, and background to very low concentrations in four samples collected from Collier County. One sample collected alongshore of Okaloosa County (Northwest Florida) contained very low concentrations of K. brevis.

Additional samples collected throughout Florida over the past week did not contain K. brevis.

Fish kills affecting multiple species, along with slight respiratory irritation, have been reported in Manatee and Sarasota counties since September 19th. Forecasts for Southwest Florida by the USF-FWC Collaboration for Prediction of Red Tides show southern, alongshore movement of surface waters, and southern, onshore movement of bottom waters between southern Pinellas and Lee counties over the next 3 days.”

Key for Results

Description Karenia breviscells/liter Possible Effects (K. brevis only)
NOT PRESENT – BACKGROUND background levels of 1,000 cells or less None anticipated
VERY LOW >1,000 to 10,000 Possible respiratory irritation; shellfish harvesting closures >  5,000 cells/L
LOW >10,000 to 100,000 Respiratory irritation, possible fish kills and bloom chlorophyll probably detected by satellites at upper limits
MEDIUM >100,000 to 1,000,000 Respiratory irritation and probable fish kills
HIGH >1,000,000 As above plus discoloration
