MARCO ISLAND — Several areas around Marco Island are continuing to report the presence of red tide at a level that could cause respiratory irritation and kill fish.
The so-called “medium” presence of red tide was reported at Cape Romano, two miles southeast of there, Big Marco Pass, Caxambas Pass and the Goodland Bridge from water samples taken Monday.
Staff members for the Collier County Natural Resources Department said Thursday that reports of dead fish have diminished since last week, though there was one report on South Marco Beach on Wednesday.
Reports of respiratory irritation also declined in the past week, with most occurring during the weekend when winds were onshore, staff members said.
County staff members advised people with respiratory illnesses such as asthma or emphysema to avoid going to the beach.
Weather forecasts call for some onshore winds during the coming weekend, which means potential effects to those with a respiratory illness.
Locations with a low level of red tide in samples taken Monday or Tuesday included Naples Bay, the Collier Boulevard boat launch ramp, Barefoot Beach, Vanderbilt Beach, Seagate and Naples Pier.
