In high enough concentrations, the algae turns water a distinct red color. The daily sample map from the Florida Fish and Wildlife Conservation Commission (FWC) shows low- and medium- concentrations of red tide as far north as Venice. The most common red tide organism in Florida is the dinoflagellate Karenia brevis (K. Red tide events have been noted in Florida since the 1800s and most certainly occurred prior to European settlement. Contact Florida Fish & Wildlife Conservation Commission (FWC) to report fish or marine life impacted. People with severe or chronic respiratory conditions such as asthma or chronic lung disease are cautioned to avoid areas with active red tide. Pinellas County Red Tide Monitoring Results & Map. If you experience any eye, nose or throat irritation while in an area with red tide, symptoms should go away if you leave the area. The presence of red tide can affect some people and impact fish and marine wildlife. That is why Texas A&M-Galveston, the University of Texas and Texas Parks and Wildlife Department cooperatively monitor the Texas shoreline looking for signs of harmful algal bloom-forming species.Red tide is a type of harmful algae bloom (HAB) caused by an increase or “bloom” in the concentration of certain microscopic algae in the water. "We know that fish-killing blooms here have occurred in the past. So, we cannot say where exactly it might be if it is indeed still in our waters. "Once an organism is introduced to an area, it can remain for a long time, but just at population densities too low for us to detect. "The red-tide organism has formed blooms in the past along the Texas shoreline," he said. Roelke said that it is possible that Red Tide is already present in waters off the Texas coast. Fish, marine mammals and birds are only the most visible. He added that there are many types of marine organisms affected by toxins produced by red tides. We do know that once the initiating mechanisms are underway, excessive nutrient concentrations enable the bloom to reach high population densities and to become widespread. State of Florida (FWC-FWRI) bloom status updates and 8-day interactive map of. "This is true for almost all harmful bloom-forming microalgae. There is no risk of respiratory irritation from Karenia brevis (red tide). ![]() "The bloom-initiating mechanisms for Karenia brevis are not fully understood, and what we know so far suggests they are complex," he said. In Florida, dolphins, turtles and manatees have died because of the surge of Red Tide. Roelke said the toxins can be deadly to organisms that consume the contaminated fish, such as aquatic mammals, birds and even humans. Regarding currents, the primary circulation pattern off the west coast of Florida is southward, eventually working its way around the southern tip of Florida then northward along the Florida eastern coastline." The dinoflagellates produce a toxin that can be fatal to fish, shellfish, birds and manatees. "If it were to happen, the likely mechanisms include accidental release of ship ballast waters containing the red- tide organism and counter currents moving in a westward direction. Large concentrations can discolor water red to brown, causing blooms to be called 'red tides.' Karenia brevis occurs in marine and estuarine waters of Florida and typically blooms in the late summer or early fall. "Yes, there is a chance the ongoing bloom could find its way here to the Texas coast, but not much of one," Roelke said. So far, it has killed more than 1,400 tons of fish in the Tampa area in the last few weeks. Daniel Roelke, professor and head of marine biology at Texas A&M-Galveston, said that Red Tide-technically called Karenia brevis-is an algae bloom that produces toxins that can kill fish.
