CHARLOTTE HARBOR — The red tide algae continues to hang on in Charlotte Harbor.

The beaches, however, remain clear of algae blooms.

The most-recent information provided by the Florida Fish and Wildlife Conservation Commission shows the amount of algae found in samples in the harbor remains high in some places. Some of the samples were taken 5 days ago and the results are available at

Three water samples contained high concentrations of the red tide algae — more than a million cells per liter of water. A fourth water sample in the Harbor contained medium concentrations — 100,000 to 1 million cells per liter.

Medium concentrations turned up in a water sample taken from a canal in Gulf Cove, at the mouth of the Myakka River.

At the mouth of the Peace River, off Laishley Park in Punta Gorda, a water sample showed low concentrations, 10,000-100,000 cells per liter.

When concentrations of red tide exceed 100,000 cells per liter, red tide blooms can lead to fish kills and that’s what happened in Charlotte Harbor.

From April 19 to April 24, state wildlife officials received more than 90 reports of fish kills throughout Charlotte Harbor.

There is some good news.

Manasota Key, other local barrier islands, Venice and Nokomis appear free for the moment of concentrated red tide blooms. Only in New Pass near Sarasota do low concentrations of red tide turn up in water samples.
