It has been a bad year for red tide throughout southwest Florida. The bloom we’ve been experiencing started last year around September and has persisted since. Blooms lasting this long are not unheard of and actually scientists have recently made some correlations between severity and duration of red tide blooms and the position of the loop current. That’s interesting stuff, but what I really want to talk about is why you shouldn’t harvest shellfish for consumption during a red tide bloom. Seems like a no brainer I know, but sadly its been happening a lot during this particular bloom.
Red tide is an example of a Harmful Algal Bloom (HAB), which results from higher than normal growth of a tiny single-celled dinoflagellate algae. Worldwide there are several algal species that can cause red, yellow, brown, and even green tide events. The species typically responsible for red tide blooms off Florida’s Gulf coast and other parts of the Gulf of Mexico is Karenia brevis. K. brevis naturally occurs in Gulf waters, but when conditions are favorable it can reproduce very quickly through cell division (every 48-120 hrs.) creating what we refer to as a bloom.
This is so not good! Late last month, FWC officer Michael Morrison observed a lionfish swimming off the Laishley Pier in Punta Gorda. This is the third documented lionfish sighting inside Charlotte Harbor, and it’s also the most up harbor. Laishley Pier is actually on the Peace River.
What’s not good about this beautiful fish? Well, for starters, it doesn’t belong here. Lionfish are native to the Indo-Pacific, but unfortunately they are well established throughout the Gulf of Mexico, the Atlantic to North Carolina, and the Caribbean.
The lionfish established here comprise two species, Pterois volitans, the red lionfish and P. miles, the devil firefish. The lions share, 93 percent of those established, are red lionfish. Genetic studies indicate that lionfish in the Atlantic are likely all descendants of a few individuals, which is consistent with the widely held belief that lionfish were introduced into the Atlantic as a result of accidental or deliberate release of aquarium pets. Isolated lionfish sightings were first documented in southeast Florida in the 1980s, and by the early 2000s they were established in that area. They then expanded to the Bermuda (2004), the Bahamas (2005), the Turks and Caicos (2008), the Cayman Islands and the Florida Keys (2009) and the Gulf of Mexico (2010). Today, they are a common sighting on any reef, in the listed areas — natural or manmade, including those off southwest Florida.
This year marks the 35th anniversary of the annual Cortez Commercial Fishing Festival. For one weekend in February, this tough and tiny village will open its doors to thousands of visitors to share the proud history and culture of one of Florida’s last true working waterfronts.
Settled by fishermen from North Carolina in the late 1800s, Cortez has never stopped fishing. Its people have withstood hurricanes, wars, recessions and storms of regulations. The village has had to adapt to shifting sands – but the perseverance and grit of the people have never wavered. Today it remains a true testament to the “real” Florida.
This region has supplied bountiful seafood to humans for thousands of years. Fishing here is good for a reason. Nestled among mangroves on Sarasota Bay, Cortez is positioned between two nationally accredited estuaries. Quick translation: the habitat here is pretty special. However, like so much of Florida, Cortez faces threats associated with an increasing human population and ever-encroaching development. But unlike so much of Florida, where similar places have simply been swallowed by the concrete, Cortez has been fighting back.
