Toxic algae threatens wildlife in Tampa Bay

TAMPA, Fla. ‹ An outbreak of the toxic algae known as red tide along Florida's west coast has spread into Tampa Bay, threatening the estuary's wildlife.

Water samples collected last week showed the highest levels of the organism since 1974, when a red tide bloom killed marine life in a wide part of the bay, said Tom Cardinale, head of the Hillsborough County Environmental Protection Commission's water quality laboratory.

"It's at a dangerous concentration that would normally cause major fish kills," Cardinale said. Dead fish have been found in areas hardest hit by the algae, although not yet in the numbers expected, he said.

The rare intrusion of the salt-loving algae in Tampa Bay is caused, in part, by the extended drought reducing the flow of fresh water into the bay, said Karen Steidinger of the Florida Marine Research Institute in St. Petersburg.

Clam farmers in southwest Florida have been seeing the effects of the red tide since August. Shellfish, which absorb the algae as food, become toxic and are closed to harvest during blooms.
