Seafood… What’s in Peak Season for October?

Seafood… What’s in Peak Season for October?

It’s October and it feels great outside. Time to fire up the grill and enjoy football with your favorite local seafood.  So what’s in peak season this month?

 

Clams – cultured Cedar Key clams are always in season and can be purchased at some local markets.

Oysters – they like the cooler months, there are a lot of ways to prepare them but we recommend cooking them

White Shrimp – other varieties of shrimp are not in peak season at this time but still available

Spiny Lobster – the Florida (Spiny) lobster is still in peak season but more available in south Florida

Stone Crab – we are JUST entering peak season for these guys, but like lobster – they are more common in south Florida.

Flounder – a local favorite this time of year – we are in peak of peak season – enjoy.

Mullet – This is a local favorite with those along the Florida panhandle.

Snapper – these are in peak season year round, but harvesting regulations reduce their abundance at the markets – so you will need to check.

Yellowfin Tuna – these have been in peak season for most of the summer; we are on the down side of it.

SPECIES OF THE MONTH…. MULLET

 

This is one of those – “either you love them or you hate them” fish. It is not news that these are not a popular food fish in much of the Gulf region.  In some locations that have an oily/muddy taste that does not appeal to many.  In those areas the fish is still abundant but is used as bait.  They are an oily fish and are preferred fried or smoked when fresh.  Mullet that sit too long develop a strong fishy taste.  Mullet roe has its fans… and its enemies.  Andrew Zimmern (Bizarre Foods) – did not care for them.  They were very popular in the Orient for a period of time, and the local mullet population suffered for it, but that fad has waned.

 

We actually have 3 species found in the northern Gulf. There are two that frequent the estuaries – the white and the striped mullet.  As the name implies, striped mullet does have body stripes as adults.  They grow a little larger than the whites and are the one of choice for eating.  At times though, the stripes on the striped mullet are hard to see.  What then?… well – the white mullet has 9 soft rays on their anal fin, the striped have 8… have fun counting those.  Another way is to look at the operculum (the bony plate covering the gills).  On FRESH mullet, the white will have a gold spot here that is missing on the striped.  The iris of the white mullet has a gold stripe that runs vertically… on the striped mullet the entire iris is gold.

 

Both species are what we call euryhaline – meaning that can tolerate a wide range of salinities. Striped mullet have been found several hundred miles inland and in Baffin Bay TX (where the salinities can reach 70 ppt).  The white mullet prefer saltier habitats and do not frequent the upper estuaries and rivers.  White mullet gather and spawn in the spring, striped mullet spawn in the fall – both spawn offshore on the continental shelf.

 

If you have not tried fried mullet, or smoked mullet dip, give a chance and see what you think. As always – enjoy our local seafood.

I’m so confused about seafood!

I’m so confused about seafood!

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.

Bacteria at the Beach

Bacteria at the Beach

Recent news reports have Panhandle Beaches trending on social media. Beaches are open and ready for holiday weekend. Here's information to help make sure you are ready too.

The threat of bacteria in coastal waters can be scary and a challenge to understand. Here is information that helps clarify the threat to beach visitors and recreational users of marine waters. This is a good opportunity to think about bacteria exposure risks related to the coastal environment that we can control. It is important to remember the probability of severe illness in a normal healthy individual is very low.

There are two different un-related groups of bacteria species that often are cited in the news.  One general group is fecal coliform and the other group are marine specific known as Vibrio.

Fecal coliform including Enterococci bacteria are used by public health managers as indicators of water quality. High levels of these bacteria can indicate an elevated health risk for beach visitors. For some individuals contact in impacted waters can result in gastrointestinal issues like nausea, vomiting, stomachache, diarrhea, headache or fever. Other symptoms might include rashes, sore throat, ear ache, and other cold-like or upper respiratory symptoms.

When “no-swimming” advisories are posted you can avoid these concerns by following warning and guidance information. Many times advisories are for specific locations due to storm run-off and water circulation patterns. If an area has a warning or is closed, usually there are better choices for swimming activities nearby. The Florida Department of Health has an established testing of many of Florida’s coastal swimming areas. The latest guidance information can be found at http://www.floridahealth.gov/environmental-health/beach-water-quality

On the other hand, Vibrio exposure that results in illness is potentially more severe. The US Centers for Disease Control and Prevention now estimate 80,000 Vibrio illnesses and 100 deaths occur annually in the United States. In perspective, The Clean Beaches Coalition estimates 180 million Americans annually make 2 billion visits to ocean, gulf and inland beaches.

According Georgia Sea Grant’s SafeOysters.org website and research, many Vibrio infections are not reported and usually do not cause serious or life-threatening illness in healthy people, although they may cause gastroenteritis (nausea, abdominal pain, vomiting, and/or diarrhea) or cellulitis (skin infection). For a Vibrio infection to occur there must be an entry point into the body. This usually is either through water entering an open wound or eating raw or undercooked seafood.

Symptoms of infection due to consumption of raw or undercooked seafood often develop in 12 to 48 hours and may include:

  • Fever/chills

  • Nausea/stomach pain/vomiting

  • Diarrhea

Individuals with weakened immune systems, chronic diseases or conditions, or undergoing certain medical treatments (see list below) are more susceptible to Vibrio vulnificus infections and are also more likely to become seriously ill or die from them. The fatality rate may be as high as 61% for Vibrio vulnificus infections in people that have been diagnosed with one or more of the following health conditions:

  • Liver disease (from cirrhosis, hepatitis, or cancer)

  • Diabetes

  • Alcoholism

  • Kidney disease or failure

  • Cancer (includes lymphoma, leukemia, and Hodgkin’s disease)

  • HIV/AIDS

  • Stomach disorders including surgery, taking acid reflux medication or antacids

  • Hemochromatosis (iron overload disease)

* If you are unsure of your risk, consult your doctor. You can always indulge in great oyster recipes that are fully cooked like Oyster Rockefeller or oyster chowder.

Perhaps one of the most common group of listed individuals are those taking acid reflux or heartburn medications. This would also include antacids and prescription medications for acid reflux and other common digestive conditions. Many of these medications work by reducing acid which can potentially increase pH in the digestive system. This lowers the natural defense barrier to several foodborne bacteria including Vibrio. If you take these medications do not eat raw or under cooked seafood. If you have any question about your risk, consult your doctor.

Shellfish harvesting is managed by the Florida Department of Agriculture and Consumer Services – Division of Aquaculture and Florida Fish and Wildlife Commission. This is done in cooperation with Florida’s certified shellfish harvesters and processors. While Vibrio counts may be higher in warmer weather, shellfish harvest areas are monitored all year. A system of specific harvest protocols are consistently maintained. Florida’s regulatory agencies and seafood industries work together with the goal of having the safest shellfish supply at all times of the year.

As mentioned earlier, Vibrio can also enter the body through open wounds. Vibrio is sometimes misnamed as “flesh-eating” bacteria.  “Flesh-eating” is not a medical term and was likely derived from the fact that tissue death, or necrosis, can occur during advanced, late stages of infection around a wound if it is left untreated, especially in those with weakened immune systems (Oliver 2005). The best advice is to seek medical attention early if you experience any of these symptoms or have suffered cut or puncture injury in coastal waters. (See Vibrio FAQs from UF/IFAS and Florida Sea Grant)

Wound infection symptoms may develop within 3 to 24 hours and include:

  • Rapid swelling, pain, and reddening of skin around wound (present in 100% of infections)

  • Large blisters, die-off of tissue around wound (30 – 50% of infections)

  • Gangrene (<10%)

If Vibrio vulnificus infections are left untreated in people at risk for serious infection, symptoms may quickly increase in severity and include:

 

  • Fluid accumulation, especially in legs

  • Blood-filled large blisters, mainly on extremities

  • Septicemia (bacteria enter and spread through blood stream)

  • Shock (rapid drop in blood pressure)

  • Death

Here are some final thoughts and advice:

  • Remember the majority of healthy individuals will not have any problems.

  • If you are recovering from illness know your limits and use the above resources to make informed decisions to protect your health.

  • Plan your beach vacation for safety but then confidently relax and enjoy the experience.

  • For additional beach safety and enjoyment of our natural resources see our other articles on the UF/IFAS Panhandle Outdoors website.

Oil Spill Science: Five years later, what have we learned?

Oil Spill Science: Five years later, what have we learned?

The Deepwater Horizon (DWH) oil spill occurred about 50 miles offshore of Louisiana in April 2010. Approximately 172 million gallons of oil entered the Gulf of Mexico. Five years after the incident, locals and tourists still have questions. This article addresses the five most common questions.

QUESTION #1: Is Gulf seafood safe to eat?

Ongoing monitoring has shown that Gulf seafood harvested from waters that are open to fishing is safe to eat. Over 22,000 seafood samples have been tested and not a single sample came back with levels above the level of concern. Testing continues today.

QUESTION #2: What are the impacts to wildlife?

This question is difficult to answer as the Gulf of Mexico is a complex ecosystem with many different species — from bacteria, fish, oysters, to whales, turtles, and birds. While oil affected individuals of some fish in the lab, scientists have not found that the spill impacted whole fish populations or communities in the wild. Some fish species populations declined, but eventually rebounded. The oil spill did affect at least one non-fish population, resulting in a mass die-off of bottlenose dolphins. Scientists continue to study fish populations to determine the long term impact of the spill.

Question #3: What cleanup techniques were used, and how were they implemented?

Several different methods were used to remove the oil. Offshore, oil was removed using skimmers, devices used for removing oil from the sea’s surface before it reaches the coastline. Controlled burns were also used, where surface oil was removed by surrounding it with fireproof booms and burning it. Chemical dispersants were used to break up the oil at the surface and below the surface. Shoreline cleanup on beaches involved sifting sand and removing tarballs and mats by hand.

QUESTION #4: Where did the oil go and where is it now?

The oil spill covered 29,000 square miles, approximately 4.7% of the Gulf of Mexico’s surface. During and after the spill, oil mixed with Gulf of Mexico waters and made its way into some coastal and deep-sea sediments. Oil moved with the ocean currents along the coast of Texas, Louisiana, Mississippi, Alabama, and Florida. Recent studies show that about 3-5% of the unaccounted oil has made its way onto the seafloor.

QUESTION #5: Do dispersants make it unsafe to swim in the water?

The dispersant used on the spill was a product called Corexit, with doctyl sodium sulfosuccinate (DOSS) as a primary ingredient. Corexit is a concern as exposure to high levels can cause respiratory problems and skin irritation. To evaluate the risk, scientists collected water from more than 26 sites. The highest level of DOSS detected was 425 times lower than the levels of DOSS known to cause harm to humans.

Giant Tiger Prawn (Penaeus monodon):

This catchy phrase coined by Robert Turpin (Escambia County Marine Resources Division) describes a recent invader to our marine waters in the past decade. Many coastal residents are aware of the invasive lionfish that has invaded our local reefs but less have probably heard of the Asian Tiger Shrimp. This member of the penaeid shrimp family, the same family are edible white, brown, and pink shrimp come from, was brought to the United States in the 1960’s and 70’s as an aquaculture project. Over the years farmers have moved from Tiger Shrimp to the Pacific White Shrimp and the last known active farm was in 2004.

The Asian Tiger Shrimp can reach lengths of 12"

The Asian Tiger Shrimp can reach lengths of 12″

In 1988, two thousand of these shrimp were lost from a farm in South Carolina during a flood event. Only 10% of those were recaptured and some were collected as far away as Cape Canaveral. No more was heard from this release until 2006 when 6 were captured; one of those in Mississippi Sound near Dauphin Island. Each year since the number of reported captures has increased suggesting they are breeding.

In the Panhandle, one individual was caught in 2011 near Panama City and 5 were collected in 2012 in Pensacola Bay. They have been found in all Gulf coast states and there has been at least 1 record in each of the Florida Panhandle counties. The future impact of this shrimp to our area is still unknown but they have a high tolerance for salinity change and consume many types of benthic invertebrates. Tiger shrimp may out compete our native penaeid shrimps and could possibly feed directly on the juveniles.  It is thought that they could possibly transmit diseases to our native shrimp.

 

Giant Tiger Prawn: This large shrimp, also known as the Asian Tiger Shrimp and the Black Tiger Shrimp, can reach lengths between 8-12 inches.  It resembles are native edible penaeid shrimp but differs in that it has distinct black and yellow stripes.

NOAA scientists are interested in obtaining samples of this shrimp for DNA studies. It differs from other local penaid shrimp in that it is larger (8-12” long), dark in color (dark green to black) and has light stripes (white to cream colored). The larva and juveniles live in the bay. Sub adults will migrate offshore for breeding. They are a tropical species that have a low tolerance for cold temperatures, showing no growth below 20°C. If you think you have found one of these shrimp, record size location (GPS preferred), and email information to ExoticReports@MyFWC.com.  You can also report to EDDMapS using the website or I’ve Got One! phone app. To learn more about Tiger Prawns view the USGS factsheet.

Enjoying Local Seafood; What’s in Peak Season for February?

Enjoying Local Seafood; What’s in Peak Season for February?

There has been an increase interest, from both visitors and residents, in purchasing local seafood.  Here we are going to define local seafood as anything caught or grown within 200 miles of your location.  For Pensacola that includes Alabama, Mississippi, and much of Louisiana; for St. Mark’s that would include the Big Bend and much of Florida’s west coast.

Though some seafood is caught, or grown, year round we will focus on species in peak season each month.  This peak season list is provided by the Gulf & South Atlantic Fisheries Foundation’s Gulf Coast Seafood Program.

So What’s in Season for February?

 

Clams and Oysters

Winter is a good time to consume local bivalves.  These creatures are filter feeders and in the warm summer months there is more bacteria in the water.  Clams are a new item for Floridians but we are growing our own in Cedar Key! (see links below). There are many seafood markets providing them so ask for them by name – Cedar Key clams.

Everyone knows the historic oyster beds of Apalachicola have suffered in recent years, but there is an effort to restore oysters to beds all across the northern Gulf coast.  Oysters are a Florida classic and though many like to eat them raw, we do recommend you cook them.  For clams most people grill, roast, or steam them.  To learn more about bivalves and seafood safety visit www.flseagrant.org

 

Pink Shrimp 

Shrimp is hands down the most popular seafood species in the Gulf region.  There are three species we harvest here, and some are experimenting with culturing, but right now pink shrimp are at peak.  Pink’s are more common in the eastern Gulf, and they may trucked into your area, but local none the less.  If you want to know how to prepare shrimp – watch Forest Gump… there are 1000 ways.

Mackerel – King and Spanish

Mackerel are members of a family of fish we call “ram letters” meaning they must move in order to flush water over their gills.  Constantly on the move, getting them to bite bait is not the hard part… it is finding them and getting the bait within their range.  This time of year is good for mackerel but king mackerel is one of the species of concern with mercury.  The current recommendation is that if the king is <31” you should not consume more than one meal / month; young children and women of child bearing age should not consume at all.  King mackerel >31” should not be consumed.  For Spanish you should not consume more than one meal/week; for young children and women of child bearing age – no more than one meal/month. Read more about mercury in Florida fish athttp://www.floridahealth.gov/programs-and-services/prevention/healthy-weight/nutrition/seafood-consumption/_documents/advisory-brochure.pdf

 

Pompano

This is a Gulf coast favorite anda great tasting fish.  I like mine grilled but there are plenty of other ways to prepare pompano.  This is one fish that many like to blacken.

 

Snapper

There are 10 species of snapper in the Gulf but the red snapper is the one most are looking for.  Snapper are in season now but availability of some species is dictated by federal and/or state  quota’s and closures.  This is one of the most popular finfish species in the Gulf.

 

We’ll let you know what is in Peak Season in March.
