ARTICLE WRITTEN BY DR. CHARLES ADAMS, FLORIDA SEA GRANT
The demand for seafood in the US continues to grow. This growth is a function of a number of factors, including the increased awareness of the healthful attributes of many finfish and shellfish products, the increased availability of several key imported, cultured species (shrimp, tilapia, pangasius), and more convenient packaging for home consumption, to name just a few. In terms of wild-caught seafood, effective management at the state and federal level helps ensure the sustainable harvest of traditionally important species, such as reef fish, scallops, flounders, mackerels, and crab.

According to the latest data from the National Marine Fisheries Service (NMFS), the US domestic fisheries fleet landed about 7.8 billion pounds of edible seafood products, valued at $5.2 billion. Florida plays an important role in this industry, particularly within the Gulf and South Atlantic region. Approximately $250 million worth of seafood is landed by the commercial harvesters in Florida on an annual basis, with some species being landed in Florida, and virtually nowhere else … including pink shrimp, spiny lobster, grouper and stone crab. But wild harvest is not the only source of finfish and shellfish products.
The commercial aquaculture industry is also growing, as the demand for species grown within controlled systems (such as catfish, oysters, striped bass, crawfish, and salmon) continues to increase. The latest NMFS data indicates that the commercial aquaculture industry in the US harvests approximately $1 billion worth of freshwater and saltwater species annually. The success story for aquacultured food items in Florida is molluscan shellfish, in particular cultured hard clams.
Though our wild seafood stocks are sustainably managed and aquaculture production is increasing, approximately 90% of the seafood consumed in the US is imported. Our domestic harvest and culture of seafood simply cannot keep up with demand. We are eating more and more seafood … with the latest NMFS estimate of annual, per capita seafood consumption being 15.5 lbs (edible meat weight). This is the highest level of per capita consumption since 2010. Even though demand is growing, consumers should be confident that the traditional species from our nation’s wild stocks will be there in the future. In addition, the aquaculture industry will help the seafood industry keep pace with growing demand. The seafood industry will continue to be an important source of incomes, jobs, and tax revenue for our coastal communities. And given the increasing number of cultured species and innovative packaging/preparation methods … now is a great time to be a seafood consumer!!
In his 137-page report to the U.S. Supreme Court published on Valentine’s Day, a Special Master appointed to oversee the case has stated, “Because Florida has not met its burden, I recommend that the court deny Florida’s request for relief.” This may not be the final word on the matter but it does sound like the “bottom line” as the highest court in the land will lean heavy on his recommendation when they rule on the case in the days to come. So, will this be the end of the decades-long battle over water rights in the Apalachicola-Chattahoochee-Flint River Basin? Considering the magnitude of what is at stake when it comes to this “Dixie-Style” water war, I seriously doubt it.

Florida argued for years that Georgia was illegally using water from its reservoir in Lake Lanier for unauthorized purposes according to the legislation that allowed the dam to be built in the first place. When that argument fell through during prior court rulings, the state sued claiming harm to the once prolific oyster fishery in Apalachicola Bay that has sustained a near total collapse that began in 2012. Florida contended that reduced freshwater flows tied to increased human needs upstream and sustained drought in the southeast had resulted in higher average salinities in the Bay, which added stressors (disease, parasites and predators), causing the crash.
Proponents of Florida’s case were ecstatic when the highest court in the land agreed to hear this case, following denials to do so in the past. Proponents on Georgia’s side of the case claimed that there was no proof that reduced flows had caused the crash and instead blamed poor management of the fishery for Florida’s woes.
Special Master Ralph Lancaster largely agreed with Florida’s assertions on the cause of the fishery disaster but still ruled against Florida’s request for relief saying that the evidence based on low flows during drought periods did not prove how a cap on Georgia’s water use during other times would provide the relief requested. Special Master Lancaster also hinted that Florida had made a grave mistake in not naming the Corps of Engineers as a party in this dispute. He said “Because the Corps is not a party, no decree entered by this court can mandate any change in the Corps’ operations in the basin.”
Georgia officials are breathing a sigh of relief as the economic impact to their state would have been substantial if this had not gone their way. On the other side of Lake Seminole at the State line, Florida’s resource managers still worry about what they can do to improve conditions in a struggling estuary on the Gulf Coast, once known locally as the “Oyster Capital of the World.”

Researchers from University of West Florida recently estimated the value of Artificial Reefs to Florida’s coastal economy. Bay County artificial reefs provide 49.02 million dollars annually in personal income to local residents. Bay County ranks 8th in the state of Florida with 1,936 fishing and diving jobs. This important economic study gives updated guidance and insight for industry and government leaders. This same level of detailed insight is available for other Northwest Florida counties and counties throughout the state.
The UWF research team is one of several contributors scheduled to present at the Northwest Florida Artificial Reef Manager’s Workshop February 22. Florida Fish and Wildlife Commission and Florida Sea Grant are hosting the workshop. This meeting will bring together about fifty artificial reef managers, scientists, fishing and diving charter businesses, and others interested in artificial reefs to discuss new research, statewide initiatives and regional updates for Florida’s Northwest region. The meeting will be held at the UF/IFAS Extension Okaloosa County Office in Crestview, FL.

I’ve spent the past 25 years studying and growing fish. When folks find out I’m a fish head, I often get a lot of questions about the safety and sustainability of many seafood products. It seems that the media and other groups have done a good job of scaring and confusing the American public to the point that some forgo consuming seafood altogether. That is such a shame because seafood is great for human health. Seafood is typically high protein, low in fat and calories and bursting with good for you stuff like omega-3s.
Seafood is either wild caught, aquacultured (farm-raised), or both. Both wild fisheries and aquaculture have their pros and cons. Overfishing, illegal fishing, bycatch, habitat degradation and lack of effective regulation have led to declines in wild fisheries. Aquaculture has been plagued with claims of pollution, disease and escapees. With all this negative press, what is the consumer to do?
You can choose your seafood based on its sustainability. Sustainable seafood has been caught or farmed in sustainable ways. And there are several groups today that make choosing these sustainable product easy. Once such group is the Monterrey Bay Aquarium. Their Seafood Watch program makes it easy for you to choose seafood that’s fished or farmed in ways that have less impact on the environment.
Using science-based criteria and input from fisheries and aquaculture experts, Seafood Watch has developed standards and guiding principles to develop consumer friendly guides. The guides are specific to each state and there is even one for sushi. These printable guides fit easily into your wallet so that you can use them anytime you purchase seafood. The guide shows with seafood items are “Best Choices” or “Good Alternatives,” and which ones you should “Avoid.” They also have an app for android and IPhone making it easier than ever to get the latest recommendations for seafood and sushi, learn more about the seafood you eat, and locate or share businesses that serve sustainable seafood.
As consumers, we have a lot of power in the seafood marketplace. With over 75% of the world’s fisheries either fully fished or overfished, we need to make smart choices about the seafood we buy and consume. By supporting fisheries and fish farms that are working hard to limit their impact on the environment we help protect the seafood we love. By using the seafood guide for your region, you’re making choices based on the best available information and supporting environmentally friendly fisheries and aquaculture operations.

September 17-24, 2016 was the nation’s 28th time to celebrate America’s coasts and estuaries during National Estuaries Week. This week helps us to remember to appreciate the challenges these coastal ecosystems face, along with their beauty and utility.
Estuaries, semi-enclosed bodies of water with both fresh and saltwater, dot the Gulf Coast of the United States from Brownsville Texas to Key West, Florida. These estuaries are important as they serve as drainage basins for many of the large river systems, and play a significant role in the nation’s seafood industry.
Florida’s six major Panhandle estuaries, which includes Perdido Bay, Pensacola Bay (including Escambia Bay), Choctawhatchee Bay, St. Andrew Bay, St. Joseph Bay and Apalachicola Bay, are unique ecosystems teeming with life and diversity. Critical habitat includes important seagrass beds that support both the larval and adult stages of fish and invertebrates. In Choctawhatchee Bay, there is also critical foraging habitat for the federally protected Gulf sturgeon (Acipenser oxyrinchus desotoi) and stream habitat for the endangered Okaloosa darter.
Choctawhatchee Bay is in Okaloosa and Walton counties in the Florida Panhandle. It is approximately 30 miles long and from three and a half to six miles wide, with a total area of 129 square miles. It is relatively shallow varying from 10 to 40 feet deep. Large portions of the western half of Choctawhatchee Bay are militarily restricted (Eglin Airforce Base). The Bay is fed by the Choctawhatchee River and numerous small creeks that feed into several bayous. The only opening to the Gulf of Mexico is the East Pass, which ironically is at the Western end of the Bay in Destin, Florida. This is where the saltwater and freshwater mix.
Continued industrial and residential development in the watershed regions that drain into many of these estuaries has impacted them in a number of ways. Pollution comes from storm water runoff, lawns, industry and farms. The shorelines are impacted by development, which causes sedimentation and in turn loss of vegetation. This reduces water clarity and habitat for wildlife.
Many organizations work to protect this estuary and reach out to others through education, restoration, and recreation events. Choctawhatchee Basin Alliance (CBA) is one such organization committed to ensuring sustainable utilization of the Choctawhatchee River and Bay. They, working with their partners, provide leadership for the stewardship of the Bay. Alison McDowell, director of the CBA, notes that 75-85% of commercially and recreationally important species that are caught in the Gulf spend part of their lifecycle in the Bay. McDowell says a key factor in the Bay’s health is monitoring the water quality and reducing erosion, and the Oyster Reef Restoration program started in 2006 does just that.
There are often opportunities for the general public to join in some of the conservation efforts taking place in the Bay. For more information, like the Okaloosa or Walton County Extension Facebook page.

Cool mornings this week reminded everyone fall is just around the corner. This subtle change in temperature inspires many of us to behave differently. It’s actually enjoyable to be outside again. Now, it’s easier to relax and drink a morning cup of pumpkin spice coffee on the porch or maybe take a brisk evening walk. These slightly cooler days not only announce the end of the dog days of summer but cue the natural world.
One of the most fascinating stories in nature unfolds this time of year. Red Drum or Redfish (Sciaenopsocellatus) are some of the most well-known and easily identified predators of the bay flats and marshes – But did you know these prized game fish can tell time? They don’t have calendars or watches but sense changes in water temperature and to the length of daylight : night time hours. Our calendar says September while their calendar says time to feed, migrate, and reproduce.
In the fish world, reproduction is known as spawning. It takes about three to four growing seasons for a red drum to mature and spawn. A mature four-year-old fish is about 28-inches in total length from head to tip of the tail. This size fish is critical to the continuation of the red drum population. This is one of the main reasons why fisheries managers regulate the number of 27 or 28-inch red drum caught. Limiting the number of this size redfish supports sustainable recruitment so there will be fish for years to come. Learn more about red drum fishing regulations by visiting Florida Fish and Wildlife at http://myfwc.com/fishing/saltwater/recreational/red-drum
When mature, red drum leave the nursery grounds of back bays and bayous and move to inlets and passes. This time of year, groups of spawning red drum may occur in entrances of the bay.
Notable members of Sciaenid or drum fish family include red drum, black drum, Atlantic croaker, and seatrout. Males have muscle fibers they vibrate against their swim bladder. The swim bladder is a hollow air filled sac fish use for buoyancy or depth control. When the muscle “strikes” the hollow sac a drum or drumming noise is created. The larger the fish the greater potential for noise. Male red drum often drum while spawning which generally occurs from sunset to sunrise.
In red drum hatcheries, light and temperature mimic the outside world and control spawning to support stock enhancement programs. In the hatchery, the drumming noise is loud and sounds like a bass drum being struck in rapid succession for about 10 seconds and then repeated. In the natural environment, Sciaenid drumming is so distinctive that researchers use hydrophones to locate and study fish species like seatrout and red drum.
While some fish species take care of their young and produce a few nurtured offspring, red drum overwhelm the odds of survival through shear numbers. During the two month spawning season, red drum spawning aggregations can produce millions of eggs each night. According to Louisiana Sea Grant, one female red drum can produce 1.5 million eggs in one night or 20-40 million per female each spawning season!
Spawning also occurs at the height of tropical storm season. Red drum eggs float on a tiny droplet of biologically produced oil that can be carried long distances by wind, waves, and water. In successful recruitment years, eggs and hatching red drum larvae make a journey into the most protected and productive portions of the bay or estuary in less than a week. Seagrass and submerged shoreline grass provide cover and protection. After rain and storms, adjacent land provides nutrients that naturally fertilize the bay waters. In response, algae and zooplankton bloom just in time to create the perfect first fish food for hatching red drum. The timing of red drum reproduction and survival is precise and elegant!
Juvenile red drum spend their next three to four-years growing to spawning adults, before migrating and starting the reproduction cycle over again.
Quick Facts: According to Texas Parks and Wildlife the oldest red drum ever recorded is 37 years old. The state record in Florida for red drum landed is just over 52 pounds and was caught near Cocoa in Brevard County, FL. A red drum caught in 1984 off the North Carolina coast holds the world record for largest red drum ever caught, 94 pounds!
