When you hear about oyster farming, you typically hear the word “seed” and how it is highly important to the future of the farm. While it might not be a typical seed that produces agricultural crops like corn, this seed is a living, breathing (albeit in the water) organism that produces a beautiful, cupped oyster. Depending on market size demand and requirements, it could take anywhere from 8 to 24 months to reach “shucking ready” size. Let’s take a dive into the timeline of an oyster, from seed to shuck.

Oyster farmers typically buy seed from an oyster nursery or hatchery, where they carefully spawn male and female oysters together in individual spawning chambers. Depending on the farmer’s needs, they can produce either diploid or triploid oyster larvae (more on triploids next week). These larvae are free-swimming for the first 2-3 weeks of their life until they develop into pediveligers (Oyster 101). Hatcheries will, for lack of better terms, mix the pediveligers with very tiny grains of ground-up oyster shells. These pediveligers will then attach to a single grain and begin to form into a “seed” oyster. Seed costs range and vary from year to year, and this cost is usually one of the biggest financial purchases oyster farmers can make. Seed is sold by size, starting at 6 millimeters (typically called size R6), and by increments of 1,000. Hatcheries and nurseries are located all along the Gulf Coast, but Florida law requires seed put in the Gulf of Mexico waters and estuaries must come from Gulf of Mexico hatcheries, and the same rules apply to Atlantic waters.

Once purchased, these seed oysters make it to their homes in beautiful nutrient-rich waters and grow at a steady rate, and can reach an overall size of 2 inches in 4 to 9 months. During those months, the seed are filtering gallons of water per oyster per day, helping sequester carbon in their shells and consuming large amounts of plankton and algae that could contribute to the eutrophication of the bays. Oyster farmers will check on the seed almost weekly, changing bag mesh sizes and sorting the seed by size. Farmers will also take this opportunity to check for any oyster predators and swiftly evict them from their all-you-can-eat buffet. Sorting is done by using a “tumbler” that has a long drum with holes of varying sizes. This tumbler also helps clean the oyster and chip away at the lip of an oyster shell, causing the oyster to grow deeper and create a beautiful cup.
Farmed oysters do not have a size limit, but most farmers stick to a 2.5 to 3-inch size oyster. These oysters have filtered over 7,000 gallons of estuary water individually and sequestered a very generous amount of carbon, in the form of calcium carbonite (more here), in their shells in their first year of life. Once deemed ready for harvest, farmers will pull them out of the water and get them quickly in the fridge, following strict biosecurity guidelines and regulations to provide a safe product year-round.

For many who grew up in the Pensacola area October meant flounder gigging season. This once popular past time involved going out at night along the shores of Santa Rosa Sound with flounder lights and gigs seeking a local favorite flounder. Everyone has their favorite recipe for this fish but in this article, we are going to focus on the fish – maybe something you did not know about it.
In the northern Gulf of Mexico, flounder are flatfish with the two eyes on the left side of the head. Locally, flatfish with eyes on the right side are called soles. We do have native soles, but all species are too small to be a food option. If you are not familiar with the “two eyes on one side of the head” idea, yes – flounder hatch from the egg looking like a normal fish, an eye on each side of the head. But earlier in development one eye slides across to the other side. This is a weird transformation and there are probably videos online, so you see how this happens – check them out. The reason for this transformation is to improve depth perception. Eyes close together give the animal binocular vision. Binocular vision does not have a wide viewing range, can basically see what is in front of it but not so much what is behind it, but it does give the animal good depth perception, it can tell how far away the prey actually is, and this is important when hunting.
Once the eyes have shifted to the left side of the head, flounders lose the pigments on the side without eyes, which becomes white, and the fish lays on its side – white side down. The cells on the “eye side” have chromatophores that allow the fish to change color to match the sand on the bottom. Another important feature of being a successful hunter. Most of know they will bury themselves in this sand as well. With their binocular vision, camouflaged body, and sharp teeth, they lie in wait to ambush predators.
You may also be surprised at how many different kinds of flounder are found in the northern Gulf of Mexico. There are 21 species listed, and they range in size from the small Spiny Flounder which can reach an average length of 3 inches, to the Southern Flounder which attains a length of 3 feet. The Gulf flounder and Southern flounder are two species that are popular seafood targets, but any decent sized flounder will do.
Flounder are found in a variety of habitats ranging from shallow seagrass beds nearshore, near structure just offshore, to artificial reefs and the base of bridges, to depths of 1200 feet in the Gulf of Mexico. Many species spend the warmer months in the estuaries moving offshore when the weather cools down to spawn. Hard northerners can trigger a mass migration and a great time for commercial and recreational fishermen alike.
It is flounder season. Whether you prefer to catch your own or buy from the local seafood market I think will enjoy one of the variety of ways to prepare this fish.

October is National Seafood Month and we are celebrating all month long! There’s no better time than now to #CelebrateSeafood. Adding seafood to your meals (at least twice a week for the amazing health benefits, according to the experts) can be exciting and fun! There are so many flavorful recipes, simple cooking methods, and fast meals so you can spend more time with your family. Simple seafood recipes are our specialty and they can be yours, too! We guarantee these simple seafood recipes and tips will help you step up your seafood game.
Here are the top three reasons you should step up your seafood game:
Live longer: Eating fish literally saves lives – eating seafood two to three times per week reduces the risk of death from any health-related cause. Plus, seafood has essential omega-3s.
Seafood is a “protein with benefits”: It’s among the highest-quality proteins and offers many additional health benefits. It can reduce your risk of heart disease, improve how you feel during pregnancy, help your child develop a healthy brain and eyes, and improve memory and sharpness in older adults.
Seafood is delicious, versatile, budget-friendly, and fast: From delicate, mild flounder to flavorful salmon, seafood can please any palate. Fresh, seasonal catches are easy on the wallet as are frozen and canned options. From start to finish, you can get fish or shellfish on the dinner table in 15 minutes or less.
Did you know 7 out of 10 deaths in the U.S. are preventable through nutrition and lifestyle changes, like adding omega-3s to your diet? Low seafood intake contributes to 55,000 deaths each year, making seafood deficiency a leading dietary contributor to preventable death in the U.S.

February is American Heart Month and when I think of heart, my thoughts turn to seafood. Perhaps that is unusual, but I love seafood and the fact that the American Heart Association recommends 1 to 2 seafood meals a week fits right into my gastronomic plans. More seafood on your table can improve your overall health and help fight off infections.
During the recent pandemic, an increase in home cooking has resulted in a rise in seafood consumption. Consumers rediscovered frozen and canned fish, a trend that continues today. Canned tuna and fish stick consumption rose as home cooks perfected their tuna melts and fish sandwiches. Home chefs throwing fish steaks, aluminum wrapped fillets, shrimp, and even oysters on the grill have raised the bar on home-cooked meals.
Other new trends on the horizon are more innovative. How do Atlantic salmon hot dogs sound? High-end canned and jarred seafood, think canned smoked oysters, are gaining in popularity as well as being quick and easy to prepare. Nose to tail is another trend that promotes maximum utilization of the whole seafood product. Cooking fish whole or tanning fish skins for an upscale leather are new ways to enjoy seafood. Want to try something new? Sea vegetables, including kelp and other seaweed are taking the culinary world by storm because of their great taste and nutritional benefits.
Let us not forget about our furry friends. Sustainable seafood-based pet treats are gaining quite a bit of market share. Seafood has one of the lowest environmental footprints of any protein, and as such makes a great, healthy, sustainable snack for fido.
Sustainable seafood, both wild and farm-raised, is an option that is good for your heart and good for the planet. Buying sustainably harvested or raised seafood is one way you can do your part to protect the ocean and ensure plentiful seafood for the future. Make a resolution to try a new product, recipe, or cooking method during this month to celebrate a healthy heart.
There are a lot of good oyster quotes. One I remember from childhood is the saying to only eat oysters in months with the letter “r,” basically September to April. I believe this originated when all oysters came from the wild. This was a way to avoid the hot months that may have led to a watery oyster, or even food poisoning. Today, with the rise of oyster aquaculture and refrigeration, oysters can be enjoyed year-round.
The Florida Fish and Wildlife Conservation Commission recently made the tough decision to shut down wild oyster harvesting in Apalachicola, FL for up to five years in response to a struggling bay oyster population threatened by water flow issues and overharvesting. This was devastating news to an area that historically produced 90% of the state’s oysters and 10% of the nation’s. On the bright side, oyster aquaculture has been steadily growing in the area and is working hard to fill some of the gap.
A team of Florida Sea Grant Agents recently made a visit to Apalachicola to learn more about this historic oyster town and how the industry is adapting. Our first stop was Water Street Seafood, the Florida Panhandle’s largest seafood distributer. Water Street provides a wide diversity of both fresh and frozen seafood, including oysters, delivering daily in northwest Florida and shipping worldwide. We visited their oyster processing facility where we saw mesh bags of oysters brought in from Louisiana and Texas. The oysters, both farmed and wild caught, are carefully cleaned and sorted, with some going to the live, halfshell, restaurant market and some shucked onsite for the shucked market.
Next, we visited one of the many new oyster aquaculture farms in the area. Oysters farms are permitted by the state and are located in waters that have been carefully evaluated for their suitability for oyster production. Small plots are leased to the farmer allowing off-bottom production in mesh bags teathered with anchors in the shallow, productive bay waters. Oyster farmers tend to their crop by turning the bags regularly to reduce fouling of the oyster shell, and sorting by size as the oyster grows. Oysters take between eight to eighteen months to reach a harvest size.
Given the increasing demand for oysters by tourists and locals, we can thank aquaculture for keeping these tasty gems on our plates. If you are lucky enough to find some locally raised oysters on the menu, take the opportunity to try something new and support a local farmer.
