The two A states in the South, Alabama and Arkansas, kick off our state aquaculture spotlight portion of our series on Aquaculture in the Southern United States. Alabama and Arkansas together contribute about 9% of all Southern aquaculture, with 102 and 55 farms, respectively. Catfish farming reigns supreme in Alabama, accounting for approximately 50% of all farms in Alabama. Baitfish farming is very popular in Arkansas, and the Arkansas baitfish industry provides over 60% of the baitfish in the United States. Let us take a quick dive into both of these A states!
Alabama Aquaculture
Just like the Song of US States we learned in grade school, we start off our state spotlights with Alabama. Alabama, especially West Alabama, is known for its catfish farms. In 1960, a small channel catfish hatchery opened up in Greensboro, Alabama, and helped jump-start the commercial catfish farming industry.
Environmental and economic factors have favored Alabama’s success, including a warm climate, suitable topography, abundant rain, low energy costs, and proximity to Auburn University’s fisheries expertise. The channel catfish is hardy and adaptable, making it ideal for farming. The STRAL Company, founded by Chester Stephens, Richard True, and Bryant Allen, was pivotal in developing catfish farming. They used methods from U.S. Fish and Wildlife Service researchers and opened the first successful hatchery.

The industry faced early challenges, including market oversupply, high feed costs, and disease outbreaks. Technological advancements, such as the paddle-wheel aerator and improved feed, helped address these issues. The establishment of the Alabama Fish Farming Center in 1985 provided essential research and support. The industry also formed marketing associations and legislative measures to combat predators and imported competition.
Down on the coastline, oyster farming is the major contributor to marine aquaculture. In Bayou Le Batre, Point Aux Pins started oyster farming in 2009. Recognized as one of the first pioneer oyster farms in Alabama, Steve and Dema Crockett opened their farm to interested oyster farmers (in fact, it was the first oyster farm I visited). The Crockett’s farm and business, eventually joined by the McClure family, were dedicated to producing off-bottom oysters for upscale restaurants and raw bars around the United States. To this day, they are credited with helping grow and spread oyster aquaculture across the Gulf.

Auburn University and their extension program has played a vital role in supporting aquaculture development in Alabama. Currently, Auburn has a lab on Dauphin Island dedicated to oyster aquaculture, an inland shrimp farm in Gulf Shores dedicated to shrimp & pompano aquaculture, and the E.W. Shell Fisheries Center, located just north of campus, dedicated to freshwater aquaculture, catfish genetics, and pond management.

The Claude Peteet Mariculture Center, located in Gulf Shores, plays a vital role in marine aquaculture research and production. It features a hatchery used to raise species such as red drum, pompano, and flounder, and earthen ponds to grow out red drum and pompano. The center also conducts research on broodstock management.

Arkansas Aquaculture
Arkansas is the birthplace of warm-water aquaculture in the United States, with the first commercial goldfish farms established in the 1940s. Since then, the industry has expanded to produce more than 20 species of fish and crustaceans, serving food markets, recreational fishing, the aquarium trade, water gardening, and aquatic weed or parasite control.
The state ranks second nationally in aquaculture production and leads the country in baitfish, largemouth bass, hybrid striped bass fry, and Chinese carp. It also ranks third in catfish production. Lonoke and Monroe counties are home to the world’s largest baitfish, goldfish, largemouth bass, and hybrid striped bass farms. By the mid-2000s, Arkansas farms were selling more than six billion baitfish annually, shipped nationwide and internationally.
Golden Shiner Minnows – Jeremy Trimpey
Catfish farming began in the 1950s and remains a cornerstone of the industry, with major economic impact in counties such as Chicot. However, baitfish aquaculture is the biggest industry in Arkansas, producing about 61% of the nation’s cultured baitfish value. Each year, six billion minnows (primarily golden shiners, fathead minnows, and goldfish) are raised on Arkansas farms and shipped nationwide. With an annual farm-gate value of roughly $23 million and a six- to seven-fold economic impact, the industry supports local economies in counties such as Lonoke, Prairie, and Monroe.
Before farming, most baitfish were harvested from the wild, often leading to ecological risks like accidental transfer of invasive species. Farm-raised baitfish, however, provide a renewable, healthy, and consistent supply. Arkansas became the hub of the industry due to favorable soils, climate, water, transportation, and pioneering farmers who developed production methods with support from the Stuttgart National Aquaculture Research Center. The baitfish industry generates jobs, supports feed mills, supply companies, and live-hauling businesses, and has adopted best management practices to conserve water, ensure biosecurity, and provide sustainable “Quality Bait from the Natural State.”
In addition to large-scale farms, Arkansas has hundreds of thousands of farm ponds managed for livestock water, wildlife, and recreational fishing. Stocking combinations of bass, bluegill, and catfish are common, with populations managed to sustain healthy fisheries.
Aquaculture is especially important in the Arkansas Delta, a region challenged by poverty and unemployment. Fish farms often serve as major local employers and generate demand for supporting businesses such as equipment suppliers, tradespeople, and transport services. Today, aquaculture ranks among Arkansas’s top ten agricultural industries, blending economic significance with ecological and recreational benefits.
UAPB Students With a Fresh Catfish Harvest – UAPB
The University of Arkansas at Pine Bluff is the only university in Arkansas that has an aquaculture program, and is home to the Aquaculture/Fisheries Center of Excellence, a research and extension center that is dedicated to aquaculture research and dissemination of problem-solving information.
While aquaculture is gradually gaining traction in the United States, it’s important to note that this approach to farming has a long and established history in many parts of the world, particularly in Asia. Asia accounts for over 90% of global aquaculture production, with China, India, and Indonesia leading the sector. The most commonly cultivated species in Asia include carp, shrimp/prawns, and tilapia.

In the United States, the Southern* states are at the forefront of aquaculture, contributing over 50% of the nation’s total domestic aquacultured species and generating $850 million in annual sales. From Louisiana’s renowned crawfish industry to the burgeoning oyster industry in the Atlantic and Gulf states, and the established catfish industry in Mississippi, Alabama, and Arkansas, the Southern states produce some of the most well-known aquacultured seafood. Farmed oysters from the South are commonly found in markets from New York to California, and Louisiana’s crawfish industry supplies much of America’s crawfish boils.
Several universities in the region are at the cutting edge of aquaculture research. Institutions like Auburn University, the University of Florida, Florida State University, Louisiana State University, the University of Southern Mississippi, Mississippi State University, and the University of Georgia are dedicated to developing the best growing techniques and finding solutions to animal health issues. Aquaculture is a rapidly evolving industry, with advancements in husbandry practices and disease resistance occurring daily.

In this series, we aim to explore aquaculture in the Southern states comprehensively, breaking down the information by state and, eventually, by species. We hope this series will illuminate the world of aquaculture in America and inspire readers to try some delicious aquacultured seafood.
In Part 2 of our series, we will delve into the aquaculture profiles of Alabama and Arkansas!

The Atlantic Tripletail (Lobotes surinamensis) is a very prized sportfish along the Florida Panhandle. Typically caught as a “bonus” fish found along floating debris, the tripletail is a hard fighting fish and excellent table fare. Just as the name implies, this fish is equipped with three “tails” that help aid it in propulsion; and also help contribute to their strong fighting spirit. In addition to the caudal fin, tripletail have very pronounced “lobed” dorsal and anal fin soft rays that sit very far back on the body, giving it the appearance of three tails (triple-tails).
Tripletail are found in tropical and subtropical seas around the world (except the eastern Pacific Ocean) and are the only member of their family found in the Gulf of Mexico. Tripletail can be found in all saltwater environments, from the upper bays to the middle of the Gulf of Mexico. In the Florida Panhandle, tripletail begin to show up in the bays beginning in May and can be found up until October/November. They are masters of disguise, usually found floating along floating debris, crab trap buoys, navigation pilings, and floating algae like Sargassum. When tripletail are young, they are able to change their colors to match the debris, albeit it is usually a variation of yellow, brown, and black. Adult tripletail can change color as well, but the coloration is not as vibrant as the juveniles. Floating alongside debris and other floating materials protects them from predators and gives them food access. Small crustaceans, like shrimp and crabs, and small fish will gather along the floating debris, looking for protection, giving the camouflaged tripletail an easy meal.
Baby Tripletail or Leaf? – Thomas Derbes II
Tripletail are opportunistic feeders that are what I classify as “lazy hunters.” Tripletail will hang out along any floating debris and wait for the food to come to them. They typically will not chase their prey items too far and will abandon the hunt if they expend too much energy. Since they are opportunistic feeders, their diet varies widely, but they cannot resist a baby blue crab, shrimp, or small baitfish like menhaden (Brevoortia patronus) that might visit their floating oasis. When further offshore, it is not uncommon to find many tripletail “laying out” on sargassum or floating debris. I personally have seen a dozen full-sized tripletail inside of a large traffic barrel 25 miles offshore that saved a skunk of a deep-dropping fishing trip.
Tripletail Caught Off An Oyster Farm – Brandon Smith
When targeting tripletail, anglers will typically sit at the highest point of the boat (some anglers have towers for spotting tripletail) and cruise along floating crab trap buoys, pilings, and sometimes oyster farms looking for Tripletail. These fish are very easily spooked, and a slow, quiet approach is best. Once in casting distance, toss your preferred bait (I typically want to have baby crabs or live shrimp when targeting tripletail) close to the floating structure, but not too close to spook the fish. You can usually watch the fish eat your bait (another added bonus) and once you set the hook, the fight is on! In the state of Florida, tripletail must be a minimum of 18 inches and there is a daily bag limit of 2 fish per person. Be very careful handling tripletail as they have very sharp dorsal and anal fins and their operculum (gill cover) is also very sharp with hidden spines.
So next time you’re out fishing and see something floating, make sure you give it a good look over. There might be a camouflaged tripletail that you can add to your fish box!
Tripletail Caught While Working Oyster Gear – Thomas Derbes
Day 2 of the Oyster South Symposium was the final day of presentations and the trade show, but it is also the day of the Shuck and Tell closing ceremonies. Another grey sky day greeted us, but the symposium was still full of oyster enthusiasts and farmers. Day 2’s talks focused more on marketing and the future of oyster farming, including discussion of a new program for Federal Crop Insurance and a panel of chefs discussing “What Chefs Want” when it comes to an oyster. The oyster disco ball also made an appearance, and I was finally able to snap a photo of that beauty!
The Famous Oyster Disco Ball! – Thomas Derbes II
Saturday’s talks started with a reflection of what Oyster South is and what it could be. Oyster South is a 501(c)(3) charitable organization that strives to connect communities and provide resources to support oyster farmers, cultivate thriving communities, and promote healthy waters (Oyster South’s Mission Statement Here). While South is in its name, the scope of Oyster South has become national with visitors and farmers from both coasts coming to collaborate and share stories of their oyster farms. I was able to talk with farmers from all over the USA, from California, Washington State to New Jersey, North Carolina and even Texas where oyster farming is still in its infancy.
After the reflection, we were treated to two awesome panels, one discussing what chefs look for in an oyster and another on making the most out of social media. Every chef has a different view of what they want in an oyster, but consistency and a certain salty yet umami taste came up as something they strive to serve. Social media also plays a major role in oyster farming and distribution. I remember when I was an oyster farmer, I quickly had to learn how to do social media as this was the best way to advertise and promote your product. Most people have Instagram or Facebook now-a-days, so being able to post your story and availability was always helpful in increasing your following and sales.
Talking About What Extension Can Do For You at Oyster South Symposium – Thomas Derbes II
After the lunch break, we had a Three-Minute Tech Talk Session. We heard from graduate students that needed input from the oyster community on their research topics, oyster farm innovators discussing their newest and greatest creations to help oyster farmers, and I was even given the opportunity to talk about what extension can do for oyster farmers. After the tech talks, we heard about the federal crop insurance program for oyster farmers, as well as a great talk from Julie Qiu (a well-known oyster blogger, advocate, writer, and founder of the Oyster Master Guild) on oyster stewardship and how important it is to oyster consumers and the oyster industry. Beth Walton, executive director of Oyster South, closed out the talks with Oyster South Looking Forward, and the future of Oyster South and oyster farming is very, very bright.
Before the Shuck and Tell, I was able to grab a quick “linner” at an incredible restaurant named Cochon. I had previously worked with a chef that came from Cochon, and his stories were the reason I made a reservation. The food in New Orleans is top notch, and Cochon was the cherry on top of a great gastronomy tour.
When it comes to oyster parties, the Shuck and Tell is the ultimate oyster experience. Farmers from all over got together to shuck their product and tell their story of why they oyster farm and the story of the oyster being shucked at the wonderful Southern Food and Beverage Museum (aka SOFAB). I was blessed enough to jump in and help shuck for some passionate oyster farmers and learn more about their farms and history. A relatively new oyster farmer at Salt Revival Oyster Company arranged for a second line to come through SOFAB, and it was an incredible way to cap off a great Oyster South weekend. The Coalition to Restore Coastal Louisiana was there to make sure all shells were recycled and used for future restoration projects.

The 2024 Oyster South Symposium was definitely one for the record books. The turnout was fantastic, and the camaraderie and collaboration between oyster farmers, researchers, and enthusiasts was a sight to behold. A major thank you to Bill and Beth Walton for always putting on an incredible symposium, and a big thank you to all the farmers who took time out of their busy schedule to share their oysters and stories. The Oyster South Symposium is an annual event, so keep your eyes peeled for the next symposium. I hope to see you at the next one in 2025!
The Second Line To Close Out Oyster South Symposium – Thomas Derbes II
When you sit down and enjoy some fresh, farmed oysters during the summer, you might notice that the oyster is not watery but yet plump and full of meat, unlike the usual wild oysters. These farmed oysters are very special and are called “triploid oysters.” What makes an oyster a triploid? Well, it all starts in the oyster hatchery and involves using tetraploid male oysters to breed with diploid female “wild” oysters.
Before we dive into triploids, let’s go over some definitions. A diploid organism contains two sets of chromosomes. As humans, we have two sets of chromosomes, and the pair is formed by a chromosome from the mother and a chromosome from the father. Triploid organisms contain three sets of chromosomes and while very rare, triploidy does happen in the wild. Tetraploid organisms have four sets of chromosomes and are usually only formed in a laboratory setting using pressure or other means to cause tetraploidy. When you breed a tetraploid oyster with a diploid oyster, the result is a triploid oyster.
A hatchery worker keeping an eye on spawning chambers with diploid oysters – Thomas Derbes II
Inside of an oyster hatchery, you will see many small breeding chambers for the oysters. When a hatchery decides to spawn oysters, they place a single wild diploid oyster in each chamber. During spawning, the hatchery will introduce a cycle of cold then warm water and this cycle is repeated until a spawn is triggered. Hatchery workers will closely watch the oysters and will shut off the water supply to any oyster that has spawned so they can trap the gametes in the chamber. You can determine the sex of an oyster by watching it spawn; a female oyster “claps” out her eggs while a male opens slightly and releases sperm into the water. When spawning for triploid oysters, the hatchery workers will only obtain the eggs from female diploid oysters and discard any diploid sperm to avoid cross contamination. During the spawn, a worker will strip the sperm from male tetraploid oysters and once all female diploids are done spawning, they will introduce the tetraploid sperm to the diploid eggs. After 30 minutes, fertilization rates are calculated and stocking densities are formed.
3-month-old triploid seed – Thomas Derbes II
Why Would a Farmer Want to Grow a Triploid Oyster?
There are many benefits for a farmer to raise triploid oysters. First and foremost, triploid oysters are sterile. This is a major benefit for the farmers during the summer months. During the summer, wild diploid oysters spawn, and when they spawn, the meat turns very thin and watery. In the Panhandle of Florida, the harvest of wild oysters is prohibited in the summer and only farmed oysters can be harvested.
Another added benefit is the increased growth rate of a triploid oyster compared to a diploid oyster. As mentioned above, triploid oysters lack the ability to spawn. Since a triploid oyster does not have to spend energy producing gametes, it puts all of its energy into growing its shell and meat. A typical diploid oyster could take more than two years to reach harvest size, where a triploid oyster can reach harvest size within 8 months (commonly 12-24 months but there are usually some fast growers in a batch).
There are more benefits of triploid oysters including selective breeding for disease resistance and environmental sustainability. With the use of triploid oysters for oyster farming, wild stocks go relatively unaffected and help contribute to more sustainable aquaculture practices. I hope this brief explanation of triploid oysters will help you understand more about the somewhat unknown world of oyster aquaculture. With demand for oysters on the rise, triploid oysters hold great promise in meeting the needs of an ever-growing oyster aquaculture industry.
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.
A cooler full of R6 oyster seed headed out to the farm – Grayson Bay Oyster Company
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.
Oyster Seed (>R16) – Thomas Derbes II
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.
Some oysters are fast growers! These were apart of the same spawn. – Thomas Derbes II
