Just in time for the Fourth of July, the outbreak of Red Tide seems to be subsiding. The state Department of Environmental Protection found very low concentrations of the organism Wednesday when sampling the Gulf of Mexico. Off the coast of Pinellas and Sarasota counties, the water also contained what researchers consider to be normal amounts of the algae. Water samples in Manatee County had low amounts. Erin Hart, an agency spokeswoman, said no complaints of dead fish or respiratory irritation were reported this week. "It does seem like it's dissipating," she said. Although better, the Red Tide still has kept shellfish harvesting areas between Pinellas and Charlotte counties closed. A decision to lift the ban likely will not be made for several more weeks.
