Algae blooms on coastal waters in Collier County

NAPLES, Fla. Concerns are rising among residents over a blue-green algae that has formed along the coast.

The algae has been spotted from the city of Naples down to Marco Island, and is being pushed by the wind.

Although the algae is harmless, it can potentially cause some fish kills, wildlife biologists said.

This algae blooms every year in the Gulf of Mexico.
