Red tide confirmed in Florida: What you need to know
Red tide is a naturally occurring, higher-than-normal concentration of microscopic algae. In Florida, the species that causes most red tides is Karenia brevis. This organism produces toxins that can affect the central nervous system of aquatic organisms such as fish and marine mammals. Red tide toxins also pose a human health risk. The toxins can aerosolize and be carried to beaches with onshore winds, leading to respiratory irritation in people. Toxins can accumulate in shellfish and result in illnesses if contaminated shellfish are consumed. Shellfish harvesting areas are closed when blooms are present.
Florida Fish and Wildlife Conservation Commission (FWC) researchers are currently monitoring two blooms along Florida’s Gulf coast, one located in northwest Florida and the other in southwest Florida.
`We confirmed the presence of both blooms in September, and they have persisted since that time,’ said Alina Corcoran, FWC research scientist. `The bloom in the Panhandle is currently affecting Santa Rosa, Okaloosa, Walton, Bay and Gulf counties. In southwest Florida, patchy blooms have been confirmed along Pinellas, Manatee, Sarasota, Charlotte and Lee counties. Extensive fish kills and respiratory irritation have been associated with the bloom in the Panhandle but in southwest Florida the effects have been less.’
Red tide public health tips:
People in a red tide area can experience varying degrees of eye, nose and throat irritation. When a person leaves an area with a red tide, symptoms usually go away.
People with severe or chronic respiratory conditions such as asthma or chronic lung disease are cautioned to avoid areas with active red tides.
In some red tides, dead fish wash ashore; during these conditions it is advised that beachgoers avoid swimming in water where dead fish are present.
Pet owners are advised that red tide poses a risk to animals brought to the beach. If a pet swims in a red tide patch at the beach, rinse off its fur and paws as soon as possible with fresh water. Also, do not let pets eat fish or drink water from the red tide.
Recreational harvesting of bivalve mollusks such as hard clams, oysters and mussels from approved shellfish harvesting areas is banned during red tide closures. To determine whether harvesting of shellfish is permitted in an area, visit the Florida Department of Agriculture and Consumer Services, Division of Aquaculture website.
FWC researchers work closely with partners, including Mote Marine Laboratory, the University of South Florida, Department of Health, Department of Agriculture and NOAA, to track blooms, share information and develop products that help to inform both citizens and scientists about bloom conditions.
`Citizen scientists play a vital role in tracking blooms. Volunteers can provide the majority of water samples for bloom tracking in regions like the Panhandle,’ said Corcoran.

Red tide sparks tourism concerns

St. Petersburg Beach, FL — Pictures of dead fish washing ashore in the Bay area are not the images that tourism officials want popping up on social media.
But red tide, say marine scientists, is now here. And how long it will last, they admit, is a mystery.
Visitors like Kathy Keleher who came to St. Petersburg from Canada to experience its cuisine and culture have seen the images of bloated fish now floating in Boca Ciega Bay.
“And then it’s gross, and it stinks,” said Keleher, “I don’t expect that at all. I expect beautiful white sandy beaches and clear water and palm trees. Not that,” she said.
It’s not what those who rely on tourism want people texting their friends and relatives back home.
“No, I mean it’s horrible for business obviously,” said Wade Parrish, head chef at O’Maddy’s Bar and Grille in Gulfport.
“You know, the smell would be a deterrent for people to come out here and sit outside and enjoy the wonderful view that we’ve got here,” said Parrish.
Bob Weisberg with the University of South Florida’s Marine Sciences lab in St. Petersburg, says red tide, or Karenia Brevis as they call it, can kill fish and even cause respiratory distress for people and marine mammals in high enough concentration.
“There is very little we can do about the red tide,” said Weisberg, describing it as simply too large.
“This particular plant can get a foothold, and when it does it then dominates,” said Weisberg, “which is what’s happening right now,” he said.
The red tide algae, says Weisberg, makes its way inland from deep in the Gulf of Mexico riding along strong underwater currents.
Scientists, he says, could better predict how long it might stick around if they were able to take more offshore observations.
Unfortunately, he says, the estimated $300,000 cost to consistently send a boat out into the Gulf of Mexico to take those readings is regularly cut out of the state budget.
Commonly, red tide will begin to dissipate this time of the year, said Weisberg.
But he also warned that there have been some seasons when the algae bloom has survived well into the summer.

The problem with Captain Wes Abell’s argument is that we all have experience on the water. That experience includes encounters with large sport fish vessels. In the overwhelming number of cases, that experience is negative. I am always surprised when I encounter a polite sport fish captain. Appreciative, definitely, but surprised. Wes, it’s your colleagues that give you a well-earned lousy reputation. I agree with the other poster that said, if you can’t manage that passage safely, find another route. Inconvenient, but what if you hurt or kill that dummy center console operator that “doesn’t get it?” If I were on that jury….
I admittedly am not familiar with the Anglefish Creek transit.
I am familiar with rules of the road and have a modicum of common sense.
If a sport boat, NEEDS, to stay on plane to transit a body of water common sense would dictate that an alternate route should be pursued.
It would seem, from looking at the map provided, that Broad Creek is an available alternative.
One thing not mentioned but should be made abundantly clear is that the captain of a boat is RESPONSIBLE for his wake. This is proven law.
Should a sports boat, pursuing a shallow channel need to stay on plane to transit that channel he is responsible for ANY damage caused by his boats wake. The reason is no release of that responsibility. A recent 2015 BoatUS Seaworthy magazine article, I believe, related a story of a sport boat who’s wake overturned a Jon boat and the sports boat was held responsible, even though there was NO, No Wake zone, for the damage caused to the Jon boat and it’s occupants.
You ‘need’ to run through a narrow channel, make sure you understand it could become a costly run.
I don’t doubt that the sportsfisher captains honestly believe that running on plane is essential, but I wonder if any actual measurement has been done to see if this belief is correct? What is the actual draft of their vessel at plane versus at hull speed; what is the actual depth at the entrances? Sure, I’d avoid ruining a $40,000 prop, but I wouldn’t place others at risk of injury or death to do so.
