The red tide organism, Karenia brevis, was not observed in samples collected over the past week. Additional details are provided below.
- In Southwest Florida over the past week, K. brevis was not observed. For additional information, please view the southwest coast report and map.
- In Northwest Florida over the past week, K. brevis was not observed. For additional information, view the northwest coast report and map.
- Along the Florida East Coast over the past week, K. brevis was not observed. For additional information, view the east coast report and map.
In Southwest Florida over the past week, fish kill reports were received for Collier County (please see https://myfwc.com/research/saltwater/health/fish-kills-hotline).
Respiratory irritation was reported over the past week in Pinellas, Manatee, and Lee counties. Additional details are provided in the Southwest Coast report.
Forecasts by the USF-FWC Collaboration for Prediction of Red Tides for Pinellas to northern Monroe counties predict net northern transport of surface waters and minimal net movement of subsurface waters over the next four days in most areas.

Key for Results
|Description||K. brevis abundance||Possible effects (K. brevis only)|
|NOT PRESENT- BACKGROUND||background levels of 1,000 cells or less||no effects anticipated|
|VERY LOW||> 1,000 - 10,000 cells/L||possible respiratory irritation; shellfish harvesting closures when cell abundance equals or exceeds 5,000 cells/L|
|LOW||> 10,000 - 100,000 cells/L||respiratory irritation; shellfish harvesting closures; possible fish kills; probable detection of chlorophyll by satellites at upper range of cell abundance|
|MEDIUM||> 100,000 - 1,000,000 cells/L||respiratory irritation; shellfish harvesting closures; probable fish kills; detection of surface chlorophyll by satellites|
|HIGH||> 1,000,000 cells/L||as above, plus water discoloration|
