The first is biology - the organism must be present in the water and it must out-compete other phytoplankton. The Florida red tide alga, Karenia brevis, needs the following components to form a bloom. brevis blooms from red tides caused by other species of algae, researchers in Florida call it “Florida red tide.” In marine (saltwater) environments along Florida’s west coast and elsewhere in the Gulf of Mexico, the species that causes red tides is Karenia brevis, often abbreviated as K.
FWC-Mote Facebook page, Florida Red Tide and Other Harmful Algal Blooms: /FLHABs/Ī red tide, or harmful algal bloom, is a higher-than-normal concentration of a microscopic alga (plant-like organism). research/redtide/monitoring/offshore-monitoring/ FWC’s red tide offshore monitoring program – a way for volunteers to help.

Red tide background info from Mote and FWC, respectively (including FAQs): /redtide and /research/redtide/. Mote’s Beach Conditions Reporting System provides shoreline observations as often as twice daily: /map. Mote’s CSIC app allows users to report when and where they experience respiratory irritation or see discolored water or dead fish - all potential indications of Florida red tide. Based on statewide results, the National Oceanic and Atmospheric Administration provides forecasts of potential respiratory irritation: /. FWC’s statewide red tide status reports (on abundance of the Florida red tide algae, Karenia brevis) are typically updated every Friday afternoon: /research/redtide/statewide (with mid-week reports on Wednesdays). A daily sampling map can also be found at the top of the current status page (updated daily at 5 pm). To report fish kills, contact the FWC Fish Kill Hotline at 80 or submit a report online.
