Concentrations of Red Tide have been detected along the Pinellas coastline, but county officials say they’re not seeing the massive fish kills that inundated the coastline when the algal crisis peaked this summer.

High concentrations of Karenia brevis, the organism that causes Red Tide, were detected in water samples taken off La Contessa Pier in Redington Beach, Madeira Beach, Johns Pass Park and Treasure Island, according to Pinellas County’s online map. Medium concentrations were found off Honeymoon Island and Pass-a-Grille Beach.

Low concentrations dot the coastline, from Clearwater Beach in the north to Mullet Key in the south. The state Red Tide map shows a hub of medium and low concentrations around Anclote Key island.

Crews haven’t had to clean up dead fish from the Pinellas coastline in a month, according to the county. Pinellas reported picking up a total of nearly 1,839 tons of dead marine life as of Sept. 4, but has recorded nothing since then. Still, that’s nearly as much as Pinellas collected during the 2018 outbreak that afflicted Florida’s west coast.

The county said it has not had to bring back the contractor who conducted this summer’s clean-ups. The city of St. Petersburg says it hasn’t had to perform any clean-ups lately, either. Pasco County officials say they haven’t seen any debris since the summer.

Red Tide blooms typically occur from August to November, so blooms could still form before the end of the year. The recent Red Tide crisis was atypical because blooms don’t typically occur in the early summer.

Scientists believe there’s a link between the recent outbreak in Tampa Bay and the April release of 215 million gallons of polluted wastewater into the bay from the old Piney Point fertilizer plant site. The nitrogen-rich wastewater could have fueled an existing Red Tide bloom.

How to stay safe near the water

• Do not swim around dead fish.

• Those with chronic respiratory problems should be careful and stay away from places with a Red Tide bloom. Leave if you think Red Tide is affecting you.

• Do not harvest or eat mollusks or distressed and dead fish from the area. Fillets of healthy fish should be rised with clean water, and the guts thrown out.

• Pet owners should keep their animals away from the water and from dead fish.

• Residents living near the beach should close their windows and run air conditioners with proper filters.

• Beachgoers can protect themselves by wearing masks.
