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.

You might have seen a floating oyster farm while driving over Garcon Point Bridge or along Scenic Highway. Many people know them for the beautiful, tasty oysters they produce, but those farms have a major ecological benefit that many aren’t aware of. First, the oysters in those cages act as a very efficient water filter, filtering upwards of 30 gallons per day. The floating farms also act as an oasis for other marine creatures, from crustaceans to finfish, and can help increase the biodiversity in the area. Oysters are also great at sequestering carbon into their shells. Today, we will go over these ecological benefits and proper etiquette when maneuvering around the farms to enjoy some of the ecological benefits of the oyster farm.
Florida Pompano Caught Off an Oyster Farm – Thomas Derbes II
Besides being tasty, oysters are very well known for their ability to filter massive amounts of water in a single day. Research has shown rates of up to 50 gallons per day in a laboratory setting, but they filter upwards of 30 gallons per day in the wild. With most oyster farms in the area having more than 500,000 oysters on their farm, that’s more than 15,000,000 gallons of water per day per farm! Oysters can filter out any excess sediments from the water, forming them into small packets and depositing the sediment on the bottom of the bay, keeping the sediments from being re-suspended. This is very beneficial to any bay or estuary as eutrophication (More Here on Eutrophication) has been an issue in almost every bay in the southern United States.
Another benefit to oyster farms is that it is a floating oasis for all types of marine creatures. Blue crabs and stone crabs are a common threat to oysters, and they love to congregate around oyster farms waiting for an easy meal from a dropped oyster or oyster spat on cages. Common bay fish, like the Spotted Seatrout, Sheepshead, and Red Drum, have been known to hang out under the cages consuming smaller finfish and crabs, but some uncommon fish like Tripletail and Florida Pompano also patrol the cages looking for a meal. Because of its ability to hold all types of fish, fishermen love to fish around the oyster farms. Fishing around oyster farms is allowed, but most farmers want the boats to stay on the boundary of the farm and not inside of it. This is due to there being lines under the surface of the water that could potentially damage any lower unit and can cut free a line of cages. Also, it is against state law to be within the boundary of the farm if you are not an authorized harvester of that lease, and I have personally seen FWC enforce those rules. As a seasoned oyster farmer once told me “We know our farm holds fish and it is okay for them to fish the farm, heck put out some blue crab traps around it, but do not mess with the cages and stay outside of the boundary and we can all live in harmony.”

Last but not least is the ability of oysters to sequester carbon and excess nitrogen into their shells and pseudofaeces (aka bio-deposits). Carbon and nitrogen sequestration is a crucial service provided by oysters that helps battle global climate change. Just as they do with excess sediments, they deposit excess carbon and nitrogen into bio-deposits that accumulate on the bottom, keeping them from being re-suspended into the waters. Oyster reefs are currently on the decline around the world, and their decline has “resulted in a forfeiture of several ecosystem services” including carbon and nitrogen sequestration and water filtration. (More Here on Carbon Sequestration)
While oysters might be tasty, we have learned about some of the ecological services oysters provide to an estuarine environment. From water filtration to increasing biodiversity to carbon/nitrogen sequestration, oysters are a major benefit to any estuary and can help fight climate change and eutrophication. Next time you see an oyster farm or reef, give oysters (and farmers) a little appreciation for their hard work in helping make the world a healthier place!
Pompano?! More like Pompa-YES! Growing up in the Panhandle of Florida, I was exposed to many great fishing seasons and opportunities, from the Cobia (Rachycentron canadum) run in the spring to the “Bull” Red Drum (Sciaenops occelatus) run of the fall, but my absolute favorite season was the Florida Pompano (Trachinotus carolinus) run on the beaches. While I enjoyed being on the boat scouring the beaches with a small bucktail jig, casting at sliver flashes in the cuts of the sandbar, I had my most memorable trips on the beach with a few rods, sand spikes, and a “flea rake.” There were no bad days on the beach (as they say, it’s better than a day in the office), and when you happen upon a honey hole, it makes for an incredible day with very little effort and usually an incredible dinner to follow. Since we are rapidly approaching peak pompano season, I will pay homage to the “Silver Surfers of the Emerald Coast” with a little overview of the life of a Florida Pompano.
Beach Fishing for Florida Pompano is for Everyone, Young and Old – Thomas Derbes II
Florida Pompano have a very wide range, from Massachusetts to Brazil, and are a member of the family Carangidae (aka the Jack Family). It is a very popular sport and commercial fishery, and its rapid growth rate makes it a prime candidate for aquaculture. Florida Pompano are highly migratory fish, and they can run from the Florida Keys all the way to Texas and back in a season. In the Florida Panhandle, the Florida Pompano run starts in April/May lasting until July, with a bonus fall run in October/November when they are returning south. When fishing off the sandy beaches of the Florida Panhandle, you can run into its cousins the Permit (Trachinotus falcatus) and Palometa (Trachinotus goodei) who often get mistaken for a Florida Pompano. Another thing they have in common with Florida Pompano is their love of crustaceans including the Mole Crab (aka Sand Fleas) (Emerita portoricensis) and Atlantic White Shrimp (Litopenaeus setiferus).
Just like most members of the family Carangidae, Florida Pompano are considered “batch spawners.” A batch spawner is when a female releases her eggs into the water column and a male simultaneously releases his sperm into the water column. Female Florida Pompano can release upwards of 800,000 eggs per spawning season, and Florida Pompano typically head offshore in early spring to October in the Gulf of Mexico to spawn, and their juveniles return to the beach to grow along the shoreline. Florida Pompano can reach an aquaculture harvest size of 12 inches within one year, and males reach maturity in 1 year whereas females mature after 2 to 3 years.

When it comes to table fare, Florida Pompano ranks very high on my personal fish list, and many chefs love serving pompano at their restaurants due to the great, mild taste and fillets that are of even thickness. Their diet of crustaceans helps yield a buttery, almost crab flavor and the meat is very flaky and white. There are many preparation techniques for Florida Pompano, from grilled whole to pan-fried, and pompano have even inspired their own cooking technique, “Pompano en Papillote,” or baking pompano in parchment paper.
Beautiful Florida Pompano Caught Off Pensacola Beach, Florida – Thomas Derbes II
When fishing for Florida Pompano off the beach, most anglers employ a large rod (usually a 10ft rod) with a 20lb fluorocarbon double drop loop rig and pyramid weight. The larger rod allows for maximum casting distance from the beach, giving beach anglers a chance to reach behind the first sandbar. Most anglers will bring either fresh dead shrimp or a flea rake with them to catch the prized bait, mole crabs. Pro tip, when casting out the rods, make sure you have a bait close to the shore in the “trough” and not just past the sandbar. (Learn More About Rigging Here!) If you plan to harvest a Florida Pompano, make sure you check your local regulations. In the Florida Panhandle, Florida Pompano must be 11 inches (fork-length) or larger with a daily limit of 6 per angler.
