| Recent genetic and toxin analyses confirmed that the bloom observed in Northeast Florida in prior weeks was composed of Karenia papilionacea, rather than Karenia brevis (the red tide organism). These two species can be difficult to distinguish using light microscopy alone, so genetic analysis was used to confirm the identification. Karenia papilionacea produces substantially less toxin than K. brevis (if any), and no brevetoxins have been detected in Northeast Florida counties during this bloom. FWC will continue to monitor the event and incorporate microscopy, genetic, and toxin analyses to best characterize the bloom population. Current Conditions Over the past week, the red tide organism, Karenia brevis, was observed at background concentrations in one sample from Northwest Florida. We continue to use satellite imagery (USF and NOAA NCCOS) to help track nearshore and offshore conditions. In Southwest Florida over the past week, K. brevis was not observed.In Northwest Florida over the past week, K. brevis was observed at background concentrations in one sample from Franklin County. Along the Florida East Coast over the past week, K. brevis was not observed.Fish Kills No fish kills suspected to be related to red tide were reported to FWC’s Fish Kill Hotline or other partners over the past week. Respiratory Irritation Respiratory irritation suspected to be related to red tide was not reported over the past week. Red Tide Status Report Courtesy of FWC |
