Crimson Tide

About the red tide

Red tide is a discoloration of the surface of a body of water that occurs when colonies of algae grow out of control. Red tide blooms occur almost every summer on the Gulf Coast of Florida and the most notable impacts are fish kills and unpleasant odors. Killed fish are large groups of dead marine life whose wind and tide conditions condense into a common area, resulting in unpleasant odors along waterfronts or areas near affected water bodies. Additionally, the red tide itself produces a distinct odor, burning eyes, and nose or throat irritation in areas adjacent or near blooming water bodies.

The answer to cleaning up dead fish can be found in the map below.

How you can help

During active red tide events

The City of St. Petersburg encourages residents and visitors to report marine life washed up on shore.

fish kills: Notify the City via the See Click Fix application or on for the fastest response.
Kills non-fish (manatees, dolphins, mammals, etc.): Notify the Florida Fish & Wildlife Commission via the FWC app or by calling 888-404-3922.

Citizens wishing to pick up dead fish on their private property may double bag the fish and throw them in their usual trash can.

All year

Algal blooms, like red tide, are made worse by nutrient pollution. Help minimize the effects of red tide by preventing nutrients from reaching our local waterways throughout the year.

  • Dispose of yard waste properly – collect yard waste and put it in your compost or wrap it up and throw it in the trash, or take it to one of the city dumps.
  • Adhere to St. Pete’s annual fertilizer ban that runs from June 1 through September 30. More here.
  • Use your sprinklers only when needed and never when it is raining.
  • Always pick up your dog’s droppings. More here.
  • Wash your car in a commercial car wash or on grass/gravel if you must wash it at home.
