              Red Tide Status Update for November 6, 2020

              Current Conditions

              The red tide organism,?Karenia?brevis, was?not observed in samples collected statewide over the past week. For additional information please view:

              Fish Kills

              No fish kills suspected to be related to red tide were reported over the past week (please see?http://m.la-feuille-enchantee.com/research/saltwater/health/fish-kills-hotline).

              Respiratory Irritation

              No reports of respiratory irritation suspected to be related to red tide were received over the past week.


              Forecasts by the?USF-FWC Collaboration for Prediction of Red Tides for?Pinellas to northern Monroe counties predict net southwestern movement of surface waters and net southeastern transport of subsurface waters in most areas over the next four days.

              Indian River Lagoon

              Over the past several weeks, a bloom of an unidentified marine/estuarine nanocyanobacterium has been documented within the Indian River Lagoon (IRL), in samples collected from the Mosquito Lagoon, Banana River, and northern to central Indian River. This bloom has been causing greenish water discoloration. Additional testing and sampling by FWRI and other partners is ongoing throughout the IRL.?For more sampling results related to this bloom, please visit?https://floridadep.gov/algalbloom.???

              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
