Red Tide Fish Kills Reported Along Central Gulf Coast

Respiratory issues and fish kills have been reported along several beaches as red tide woes continue along the Central Gulf Coast.

MANATEE COUNTY, FL — As a persistent Florida red tide bloom continues to plague the central Gulf Coast region of Florida, reports of fish kills and people experiencing respiratory irritations have come in from multiple beaches. The bloom that stretches from Pinellas County south to Lee has been an ongoing concern for several months.

In its Friday Red Tide Status report, the Florida Fish and Wildlife Conservation Commission noted that no water samples taken in the region over the past week showed high concentrations of the red tide organism. Even so, multiple reports about respiratory irritations and fish kills did roll in.

Red tide, also known as Karenia brevis, is a naturally occurring organism found in Gulf of Mexico waters. When it accumulates in large amounts, it can kill fish and cause respiratory problems for people and animals.

Toxins in red tide can “enter the air and cause respiratory irritation among beachgoers, such as coughing, sneezing or a scratchy throat,” according to Sarasota’s Mote Marine Laboratory. Mote scientists conduct year-round monitoring of Bay area waters.

According to FWC, red tide was found in water samples as follows over the past week:

  • Pinellas County – background to very low concentrations in three sample
  • Manatee County – background to very low concentrations in six samples
  • Sarasota County – background to medium concentrations in 26 samples
  • Charlotte County – background to low concentrations in six samples
  • Lee County – background to low concentrations in 21 samples

A sample taken from the east coast’s Brevard County also contained background concentrations, FWC reported.

Florida red tide blooms are known to be patchy, according to Mote Marine. That means a beach with a high concentration of the organism can be located close to another that’s not experiencing issues.

Beachgoers with respiratory conditions, such as emphysema and asthma, may be more susceptible to red tide irritants. FWC recommends these public health tips when red tide is present:

  • People who experience issues, such as nose, throat and eye irritations may want to leave the immediate area
  • Those with severe or chronic respiratory conditions should avoid areas that are known to have active red tide
  • When dead fish are present alongshore, it is advised that beachgoers avoid swimming in the water
  • Red tide may also pose a risk to pets. Pets should not eat fish or drink water from water with a high concentration of red tide
  • Recreational harvesting of such mollusks as hard clams, mussels and oysters is banded when red tide is present. To find out if harvest of shellfish is available in an area, visit the Florida Department of Agriculture and Consumer Services, Division of Aquaculture online.
