Many species of animals go through dramatic swings in population numbers over time. For some, these fluctuations are related to the dynamics of a natural symbiotic connection such as a predator-prey relationship. A classic example of this is the famous snowshoe hare/lynx model taught to all wildlife ecology students. The lynx numbers follow the hare numbers with a lag in the population upswings and downswings. For other species, it may simply be related to changing environmental conditions that they either do not tolerate well or that they thrive in. This is primarily the case with our panhandle bay scallop populations from year to year. During the time I’ve lived in North Florida I’ve experienced both ends of the spectrum during local scallop seasons. Some years, you can limit-out as fast as you can pluck them from the sea grass bed. Other times, the old adage of “finding a needle in a haystack” comes to mind. Over the past few years we have experienced some of these dramatic swings for various reasons.
Bay Scallop Argopecten iradians
Bay scallops are mostly an annual species, with spawning taking place as water temperatures drop quickly during fall cold fronts. Harvest numbers the following summer are a result of larvae that matured in a single season. Occasionally, you will find an old “mossy-back” that is significantly larger and likely a holdover from the previous season. During spawning, a single scallop can release millions of eggs but very few survive to adulthood and throughout their brief lifespan they are susceptible to many mortality factors.
Predation by crabs, sea stars and several species of marine snails takes a toll but is generally not the driving force in significant declines.
One factor that does have population-level impacts is the amount of rainfall locally. Too much freshwater will create physiological stress and kill scallops over large areas. They can also be hammered by extreme heat or cold events due to their nature of inhabiting relatively shallow coastal waters. Other population pressures may not be so obvious because they sneak up on scallops gradually rather than happening all of a sudden. Factors such as propeller scarring in seagrass beds and siltation from terrestrial runoff or human activities, can have a cumulative effect that gradually degrades the seagrass habitat where scallops live. Another factor that can cause near-extinction of local populations is the occurrence of harmful algal blooms such as red tide. The toxins produced by these marine dinoflagellates will kill fish, marine mammals and shellfish alike. This is what happened to the scallops in St. Joseph Bay during the fall of 2015 when a red tide bloom killed most of the spawning population.
A more recent event in St. Joseph Bay, that put a damper on the 2017 season, was a bloom of a different marine dinoflagellate species known as Pseudo-nitzschia. This organism can produce a toxin known as domoic acid which can cause amnesic shellfish poisoning in humans. Thankfully, it is not expected to harm the shellfish themselves and next season may be a real bumper year. That is, if everything else that can go wrong for a scallop decides to give them a bit of a break. When environmental conditions are good, it is astounding what Mother Nature will provide.

Actually, if you like seafood – it’s all good! However, not everyone does and sometimes when this question is asked they are interested in not how it taste but where the seafood came from.
In recent years, there has been a move across the country to learn more about where their food comes from. Whether that is because they are concerned what the livestock and chickens have been fed, their living conditions, or whether they came outside the United States – more people are asking and it is affecting how they purchase their food. Is it the same for seafood?
In some cases, yes. Several years ago, I ran the marine science program at Washington High School. We were discussing whether, with a growing human population, the ocean could sustain the demand for seafood. Would we need to focus our production on aquaculture? We decided to survey locals to see whether (a) they liked seafood, and (b) if so, would it matter whether the product came from the ocean or a farm. Over a 10-year period, we found that (a) the percentage of locals who did not like seafood increased. (b) Those who did like seafood did not have strong feelings whether it was from a farm or from the sea. Curious as to why those who did not like seafood felt that way, we followed up with those questions and found it was not as much a concern with seafood safety in that they just did not like the taste of it. Of course, this was a high school science project and not a formal science investigation, but they did a good job with it and the results were interesting.
That was almost 20 years ago, do people feel the same? According to Dr. George Baker (Florida Sea Grant), yes… things are about the same. If they can get access to wild harvested seafood at a good price, they will buy. If it is not available, or to expensive, they will, purchase farm raised. Moreover, more people do not like seafood.
What about the local issue? In California, there is a program that allows you to find out which boat captain caught your fish. In Florida, there are studies going on to determine what type of filet you are actually buying. As with produce and livestock, people seem to be interested in where their seafood comes from – and for many, if effects where and how they buy seafood.

So what is local?
Well, we call any seafood product harvested or cultured within 250 miles local. For Pensacola, that would include Alabama, Mississippi, and eastern Louisiana. We know that between 80-90% of the seafood you currently purchase is imported from both commercial fishing and aquaculture overseas. That said, local seafood is still here and available.
The commercial fishing in Pensacola goes WAY back. It was one of the first industries to get off the ground shortly after Florida became a U.S. territory. According to Dr. Jack E. Davis, in his book The Gulf; The Making of an American Sea, Cuban fishermen harvested seafood from the Gulf coast of peninsula Florida prior to our becoming a territory. Shortly after becoming a U.S. territory, New England fishermen came to harvest the Gulf, including one by the name of Leonard Destin. Soon a fishing industry was operating in Pensacola. They sold a variety of species but in 1840 they found red snapper – and the boom was on. Shrimp followed but water quality, habitat loss, and overharvesting have plagued the industry over the years. Fishermen did well for a time, then the landings decreased, the fishermen believed the fish had moved, and so the fleet would move. This continued until they have literally moved all over the Gulf of Mexico seeking fish. At this point quotas had to be initiated and regulation has been the norm ever since. Add to this an increase interest in recreational fishing, increasing the number of fishermen, and increased regulation with this sector. Today we can include the introduction of invasive species as another stressor.
All that said, local seafood is still available. Some species have become quite pricey, but they are still available. The Gulf & South Atlantic Fisheries Foundation created a Gulf Coast Seafood Species Chart. This chart indicates when selected species are in peak season for commercial harvest. This chart suggests they are in season year round but there are peak months. It varies from one state to another, but the list below includes Florida and Alabama.

The health benefits from consuming seafood are understood. We certainly think it should be part of your of weekly dinner menu. There are concerns for safety in some seafood products, as in mercury and king mackerel, and we will address that in another article – but the lack of consuming seafood can create health issues as well. We hope you enjoy local Gulf seafood.

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.”

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.
