TAMPA, Fla. — The Bay area is continuing to see the effects of red tide. 

Some beaches in Manatee County are coated with dead marine life, which is impacting the tourism industry.

The county has pulled more than 160 tons of dead fish and debris from the area beaches. People say you can smell the red tide more than a mile from the coast in some spots. 

At four Sarasota beaches, including Venice Pier Beach and Longboat Key Beach, there is a no swim advisory.

Siesta Beach was also marked with a no swim advisory last week, but is now back open.

However, lifeguards in the area are being offered masks for protection to help with breathing while out on the coast. 

In Pinellas County, there is only small concentrations of toxic algae that causes red tide, according to the most recent report from Florida Fish and Wildlife. 

Dr. Deepa Verma says if you choose to take a dip in a beach that has red tide present, proceed with caution.

"Bacteria are very hearty, so it takes a lot to really expunge them or eradicate them," she said. "Just make sure you don't have anything active that's going on. Be aware."

Experts say the few fish that have turned up on Pinellas County beaches may have floated in from farther south. 

Experts say they do not know when this will end. They say it is all about the wind and currents.
