1844:

First fish kill in Florida suspected to have been caused by Red Tide occurs. Other outbreaks follow in 1854, 1856, 1865, 1878, 1879, 1880, 1882, 1883, 1885, 1908, 1916, and 1935.

November 1946 - September 1947:

Resort beaches from Tarpon Springs to Marathon are covered with dead fish, reportedly at a rate of up to 100 pounds per foot of shoreline. Shortly after local officials go to Washington to seek federal help, the outbreak is routed by a Gulf hurricane. University of Miami researchers discover the micro-organism that is the cause of Red tide and name it Gymnodinium breve. It is still considered to be the most severe Florida Red Tide on record.

June - December 1952:

Red Tide affects a 400 square mile area from Boca Grande to Sanibel Island; Clearwater Mayor Herbert Brown suggests using Air Force planes to fire-bomb a 150 mile area of dead fish with napalm to keep them from coming ashore.

September 1953 - Summer 1954:

Small but persistent Red Tide blooms occur from Pinellas County south to Sanibel Island, causing a $3.8 million loss to the tourist industry in Clearwater alone.

September - December 1957:

Red Tide outbreak results in what are called "catastrophic mortalities" of marine animals along the coast from Anclote Keys to Cape Sable. Officials try spraying copper sulfate from crop dusters planes on gulf waters from Clearwater to Naples, but discontinue the program because of the high cost and because the chemical damages other sea life. State prisoners are used to clean up dead fish at Clearwater Beach.

October 1959:

Red Tide kills fish along a 120 mile stretch of the gulf coast from Clearwater to the Fort Myers area. At Sanibel Island, one of the hardest hit areas, children are reported to be stacking dead fish like "cordwood" on the beach.

April 1963:

Red Tide observed from Tampa Bay to Marco Island. Authorities consider it the worst fish kill ever recorded in Tampa Bay. More than 150 tons of fish are removed from the bay's shorelines, including a dead 700 pound grouper that floats ashore at Coquina Key.

July 1964:

First documented Red Tide north of Tarpon Springs occurs. The 14,000 square mile bloom is centered in the Apalachee Bay area and as far south as Piney Point.

August 1967 - January 1968:

Red Tide first reported 10 miles west of St. Pete Beach and develops into a major bloom lasting until November. Fish kills off the Fort Myers area are reported into January. Officials close Pinellas, Hillsborough, Manatee, Sarasota and Charlotte counties to shell fishing.

May - September 1971:

Red Tide first reported in Fort Myers area and then moves north to Tampa Bay. Lost tourist dollars and clean-up costs an estimated $20 million. Thousands of dead fish fill Tampa Bay and wash up into the canals and bayous in St. Petersburg, primarily in the Shore Acres and Snell Isle areas.

January - June 1974:

Red Tide first reported in Fort Myers area and then moves north to Tampa Bay. Tourists resort to wearing gas masks on the beaches to beat the stench; loss to the tourist industry is estimated at over $15 million. City workers stretch nets across small bayous in St. Petersburg to keep out dead fish and ducks.

January - September 1982:

Red Tide ranges from Pasco County to Naples, killing 39 manatees in the Caloosahatchee River area in February and March.

September 1986 - March 1987:

Red Tide blooms as far as 79 miles offshore. Shell fishing banned in counties from Pinellas southward to Lee, including Hillsborough County.

March - May 1989:

Red Tide outbreak occurs on Pinellas and Manatee beaches, killing thousands of fish and rendering shellfish poisonous in the two county area.

July - August 1991:

Red Tide begins in Sarasota and Manatee counties and slowly moves north to the Pinellas beaches. Harvesting shellfish, oysters and clams anywhere along the West Florida shoreline is banned.

September 1992 - January 1993:

Shell fishing areas from Charlotte to Pinellas counties are closed as a result of two Red Tide outbreaks, one in September and one in November.
