Walton County in the Florida Panhandle has 26 miles of coastline dotted with 15 named coastal dune lakes. Coastal dune lakes are technically permanent bodies of water found within 2 miles of the coast. However, the Walton County dune lakes are a unique geographical feature found only in Madagascar, Australia, New Zealand, Oregon, and here in Walton County.
What makes these lakes unique is that they have an intermittent connection with the Gulf of Mexico through an outfall where Gulf water and freshwater flow back and forth depending on rainfall, storm surge and tides. This causes the water salinity of the lakes to vary significantly from fresh to saline depending on which way the water is flowing. This diverse and distinctive environment hosts many plants and animals unique to this habitat.
There are several ways to enjoy our Coastal Dune Lakes for recreation. Activities include stand up paddle boarding, kayaking, or canoeing on the lakes located in State Parks. The lakes are popular birding and fishing spots and some offer nearby hiking trails.
The state park provides kayaks for exploring the dune lake at Topsail. It can be reached by hiking or a tram they provide.
Walton County has a county-led program to protect our coastal dune lakes. The Coastal Dune Lakes Advisory Board meets to discuss the county’s efforts to preserve the lakes and publicize the unique biological systems the lakes provide. Each year they sponsor events during October, Dune Lake Awareness month. This year, the Walton County Extension Office is hosting a Dune Lake Tour on October 17th. Registration will be available on Eventbrite starting September 17th. You can check out the Walton County Extension Facebook page for additional information.
My son and his girlfriend were visiting last week and wanted to go fishing. Since she had never been deep sea fishing before, we decided that the best course of action would be to take the short four-hour trip on one of Destin’s party boats.
Party boats, also known as a head boat, are typically large boats from 50 to 100 feet long. They can accommodate many anglers and are an economical choice for first-time anglers, small, and large groups. The boat we went on holds up to 60 anglers, has restrooms, and a galley with snacks and drinks, although you can also bring your own. The cost per angler is usually in the $75 – $100 range and trips can last 4, 6, 8, or 10 hours.
We purchased our tickets through the online website and checked in at the booth 30 minutes before we departed. Everyone gets on and finds a spot next to a fishing pole already placed in a holder on the railing. For the four-hour trip, it is about an hour ride out to the reefs. On the way out, the enthusiastic and ever helpful deckhands explain what is going to happen and pass out a solo cup of bait, usually squid and cut mackerel, to each angler. When you get to the reef, you bait your hooks (two per rod) and the captain says, “start fishing.”
The rods are a bit heavy and there are some tricks you need to learn to correctly drop your bait 100 feet to the bottom of the Gulf. The deckhands are nearby to help any beginners and soon everyone is baiting, dropping, and reeling on their own. There are a few hazards like a sharp hook while baiting, crossing with your neighbor’s line and getting tangled, and the worst one, creating a “birds nest” by not correctly dropping your line. Nothing the deckhands can’t help with.
When you do finally catch a fish, you reel it up quickly and into the boat where a deckhand will measure it to make sure it’s a legal species and size and then use a de-hooker to place the fish in your bucket. After about 30 to 40 minutes, the captain will tell everyone to reel up before proceeding to another reef. At this time, you take your fish to the back of the boat where the deckhands put your fish on a numbered stringer and on ice.
For the four-hour trip, we fished two reefs. We had a lucky day with the three of us catching a total of 16 vermillion snapper, the most popular fish caught on Destin party boats. It’s a relaxing ride back to the harbor during which the deckhands pass the bucket to collect any tips. The recommended tip is 15-20% of your ticket price. These folks work hard and exclusively for tips, so if you had a good time, tip generously.
Once back in the harbor, your stringer of fish is placed on a board with everyone’s catch and they take the time for anyone that wants to get some pictures with the catch. Then, you can load your fish into your cooler, or the deckhands will clean your fish for you for another tip. If you get your fish filleted, you can take them to several local restaurants that will cook your catch for you along with some fries, hush puppies and coleslaw. It is an awesome way to end your day.
The Snake Watch Project is one that is helping residents in the Pensacola Bay area better understand which species of snakes are most encountered, where they are encountered, and what time of year. The project began in 2022 and over the last two years between 50-60% of the 40 species/subspecies of snakes known in the Pensacola Bay area have been encountered. The majority of these encounters have been in the spring, with garter snakes, black racers, banded water snakes and cottonmouths being the most common.

The 1st quarter reports cover the winter months, and you would expect fewer encounters – but encounters do happen. In 2022 there were only 6 encounters during the winter months. There was one mid-sized snake (between 12-24” maximum length), 2 large snakes (greater than 3’ maximum length), 1 water snake and 2 cottonmouths for a total of five species. In 2023 there was a significant increase in 1st quarter reports. There were 57 encounters (26% of the total for the year) and 13 species logged.
Two species of small snakes (less than 12” maximum length) were encountered three times.
Three species of mid-sized snakes were encountered nine times, this included an encounter with the eastern hognose snake.
Six species of large snakes were encountered 17 times. These include the rarely seen eastern kingsnake and Florida pine snake.
Three species of water snakes were encountered, including the green water snake.
The cottonmouth was encountered 10 times during the 1st quarter of 2023.
This increase in sightings may be more a result of more people interested in the project than a true increase in snake activity, but it does provide us with information on snake activity during the winter months. Eastern garter snakes, eastern ribbon snakes, banded water snakes, and cottonmouths were the most frequently encountered.

Snake encounters during the 1st Quarter of 2024 are down. This year 27 encounters occurred logging eight species. The cottonmouth continues to be the most encountered snake in our area and the only one who was encountered in double digits (n=11). Other species encountered included the eastern garter snake, eastern ribbon snake, gray rat snake, corn snake, southern black racer (encountered every month), eastern coachwhip, banded water snake (encountered every month), and the cottonmouth (also encountered each month this quarter).
We will continue to log encounters during the spring. If you see a snake, please let Rick O’Connor know at roc1@ufl.edu.
Organized and sponsored by Florida Sea Grant, the “Stem to Stern” workshop in November 2023 at the Emerald Coast Convention Center marked a significant gathering in marine conservation and management. This event drew together legal experts, representatives from the Florida Fish and Wildlife Conservation Commission (FWC), local marine resource coordinators, law enforcement, and industry stakeholders to tackle critical issues facing Florida’s marine environments. Through discussions that ranged from legal frameworks for boating and waterway access to environmental conservation strategies, the workshop facilitated a deep dive into the complexities of marine policy and stewardship.

Even though oysters have a hard shell that even humans have a hard time opening, they do have natural predators in our waters that can easily slurp up a couple dozen. Your usual oyster slurping suspects include oyster drills, blue crabs, and fish (such as the black drum). In this article, we will focus on the 3 major predators that contribute the most toward natural mortality in oysters here in the Florida Panhandle.
The Oyster Drill
When it comes to the marine snail world, oyster drills would win an oyster-eating contest. Oyster drills (Urosalpinx cinerea) are marine gastropods that grow to sizes of 0.5 – 1 inch. Oyster drills can be found all along the Atlantic coast of North America and the Gulf of Mexico, and they have been accidentally introduced into Northern Europe and the West Coast of North America. These small but mighty snails have become specialized in consuming oysters. Using chemotaxis, they locate their prey oyster. Once they find it, they secrete an enzyme to soften a portion of the oyster shell. Once softened, they drill into the shell and siphon out oyster meat. Oyster drills have been known to occur in great numbers when the environmental conditions are prime and can wipe out not only entire oyster beds but also clam beds. Oyster drills do have natural predators as well, but these predators also consume oysters.

The Blue Crab
Most of us know about the very tasty blue crab (Callinectes sapidus), but many do not know that it is a major consumer of oysters, especially on an oyster farm. Blue crabs are a decapod crab (meaning 10 legs) of the swimming crab family Portunidae. Blue crabs can indeed swim and their last leg on each side has developed into what are called paddle fins. Juvenile oysters are the main target for blue crabs, but they have been observed eating adult oysters when given the opportunity. On an oyster farm, blue crabs can get into an oyster bag when they are very small. Once inside, they have an all-you-can-eat buffet of oysters, and can quickly wipe out a bag of oysters. Oyster farmers have to be very cautious and must either remove the blue crabs manually or dry their bags out in hopes of destroying any blue crabs. Blue crabs can easily break open a juvenile oyster, but for them to consume an adult oyster, they will wait for it to open to feed before shoving a claw inside of the shell to keep the oyster open. Once they have their claw in the shell, they will use their other claw to consume the oyster.

The Fish
Even though oyster-eating fish like black drum (Pogonias cromis) and sheepshead (Archosargus probatocephalus) are much bigger than snails and crabs, they tend to contribute less to oyster mortality on oyster farms. However, during certain seasons wild oysters and other shelled invertebrates can contribute up to 33% of a black drum’s diet (more here). Fish will usually congregate around oyster beds and farms, but they are more interested in consuming oyster predators like crabs and snails. The black drum is a fish that was built for oyster consumption. While black drum lack sharp teeth, they have crushing plates in their throat that can crush an oyster shell which allows the drum to eat the oyster meat. Many oyster farmers welcome these fish on their farms as a free source of anti-fouling and predator deterrent (in the form of consumption).

There are many more oyster predators, but these are the top 3 in terms of threat and ability to consume/do detriment to oyster beds and farms in the Florida Panhandle. While oyster drills rank up towards the top, crabs and fish can also greatly contribute to natural mortality.
