All fish, minus opah and some tunas, are cold blooded. Thus, their body temperatures are regulated by the environment around them. Every fish species has an optimal temperature range — not only for survival, but also for growth and reproduction. Fish exhibit control over their thermal environment by seeking waters that are closer to their temperature optimum when waters become too warm or too cool.
High and low temperatures that are lethal for a particular species determines the distribution and abundance of its population. With water temperatures trending upward — the result of climate change — many fish are responding by shifting their latitudinal range, expanding their range, and/or moving to
Catch and Release is an important conservation tool. Catch and release fishing helps to sustain native fish populations by allowing more fish to remain and reproduce in the ecosystem. This practice provides an opportunity for more people to enjoy fishing and to successfully catch fish.
But, catch and release fishing is not perfect. Some fish still die. Including some that swim away after being released. Caught and released fish can die for many reasons including: hook injury, handling practices, air exposure, and barotrauma (swim bladder trauma in deep water fish). Released fish sometimes die immediately, but in other cases mortality due to angling stress may take days.
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.
The National Sea Grant Program is celebrating 50 years of Science Serving America’s Coasts (for a 30 second video, or even better, a 10 minute video). To commemorate Sea Grant’s cherished history of working with fishing communities, UF/IFAS Extension Florida Sea Grant Agents Libby Carnahan (Pinellas) and Angela Collins (Manatee, Hillsborough, Sarasota) hosted “A Salty Heritage: Celebrating the Fishing History of Tampa Bay.” The program, held at Weedon Island Preserve in December 2016, was open to the public and highlighted the bounty and diversity of fishing opportunities within the Tampa Bay region. Invited panelists included commercial and recreational representatives, and featured crabbers, seafood wholesalers, and fishermen. Each speaker told tales from their past, provided insight into their industries, and shared their visions for the future.
They’re feisty, fearsome predators, even cannibalistic; and they’re what’s for dinner. At least at my house! Let’s talk stone crab!
Two commercial species of stone crab coexist in the state of Florida, the Florida stone crab (Menippe mercenaria) and the Gulf stone crab (Menippe adina). These two crabs are managed as a single fishery in the state. The Florida stone crab (our crab) occurs in the eastern portion of the Gulf of Mexico and extends from North Carolina throughout peninsular Florida and the Caribbean. The Gulf stone crab occurs principally in the northern and western Gulf of Mexico.
The Florida stone crab inhabits mixed seagrass-hard bottom habitat. Adult crabs dig burrows under the seagrasses or excavate holes in emerged rocks on the seafloor. The Gulf stone crab also occupies those habitats, but prefers muddier bottoms and oyster reefs. Both species feed primarily on mollusks, including scallops, clams, conchs, and oysters, which they crush with their powerful claws. Predators that feed on stone crabs include octopus and humans.
Sea Grant is turning 50! Come and Celebrate 50 Years of Putting Science to Work for America’s Coastal Communities.
What: A Salty Heritage: Celebrating the Fishing History of Tampa Bay
When: Saturday, December 3, 2016
Where: Weedon Island Preserve Cultural and Natural History Center, 1800 Weedon Drive, St. Petersburg, FL 33702
About: Tampa Bay has a rich heritage as a fishing community. To celebrate Sea Grant’s 50th Anniversary, we are holding a Marine Science Open Classroom (10 am – 12 pm) that will be fun for the whole family! Then we’ll have cake and refreshments in the lobby (12 – 1 pm), and will proudly finish the day by hosting some of the saltiest fishermen in the bay for an open panel discussion (1 – 3 pm) with the audience! Invited panelists range from crabbers, spearfishers, wholesalers, and recreational and commercial anglers. Each speaker will tell tales from the past, provide insights into their profession, and give us a glimpse of what they see as they look to the future. A question and answer session will follow the panel discussion.
We hope that you will join us for part (or all) of the day to learn about the resources Tampa Bay provides to our community.
Fishing license rules can be confusing, especially if you’re new to Florida or don’t know where to get good information. We have fishing license requirements for fresh water and salt water. We also have fishing regulations that apply to state waters and federal waters, and they are not always consistent. Knowing how and when they apply to you is important for ensuring a good fishing trip doesn’t go sour when law enforcement arrives. Licensing and regulatory information about fishing in Florida can be found at MyFWC.com.
If you are going fishing in Florida, you can assume you need a fishing license, unless you meet one of the state’s exemptions, are fishing from a pier that has a valid “pier license” (most of them don’t), or are fishing on a licensed charter boat.
Spotted seatrout are a sought after fish species for both recreational and commercial fishermen in Florida. They are distributed along the Atlantic and Gulf Coasts from Cape Cod, Massachusetts to southern Florida and throughout the Gulf of Mexico to Carmen Island in the Lower Gulf of Campeche, Mexico. They are most common along the Gulf coast from the west coast of Florida to Texas.
Spotted seatrout are unique in that that their entire life is estuary dependent and they rarely migrate far from the estuaries where they were spawned. They can tolerate wide salinities and may be found in waters ranging from fresh to hyper saline.
In southwest Florida, spotted seatrout are generally found associated with vegetated areas, such as seagrass beds and mangroves, and in close proximity to deep areas for seeking refuge from extreme temperatures. In the northern Gulf where seagrass is sparse, spotted seatrout are found in and adjacent to marshes, over sand, mud, shell reefs, and around oil platforms.
Every so often I receive photos taken by anglers who have observed fish abnormalities while fishing. The typical question I get is, do you know what this is? If not, can you help me find someone who does? Regardless of whether or not I know the answer, my response is always the same; report it to the Florida Fish and Wildlife Conservation Commission’s (FWC) Fish Kill hotline. But the fish isn’t dead! It’s OK, FWC’s Fish Kill hotline is maintained by their Fish and Wildlife Health section (FWH), and that section is also interested in fish abnormalities.
