An Update on the Lionfish Situation in the Panhandle
In the past couple of years, we have posted articles about the lionfish during NISAW week. A question we hear more now is – “how is lionfish management going?”
First, they are still here…
Wish I could say otherwise, but they are here and probably always will be. Since the time of the first sighting in 2010 their numbers have increased. In 2013 Dauphin Island Sea Lab reported densities on artificial reefs at 14.7 lionfish / 100m2; which was among the highest recorded in the western Atlantic and the time. At some point all populations reach carrying capacity and begin to level out; we do not know if this has begun to happen yet.
Second, removal…
Scientists have suggested that effective management would require a minimum 25% of the population to be removed during removal events. We are not sure how many are out there but FWC does maintain records on how many have been removed.
In 2014 there were 28 derbies held in Florida; 10 of those in the panhandle (36%). 17,246 lionfish were removed; 8,643 (50%) were from the panhandle. This could be because of a stronger effort (we had 2 more derbies than the west coast of peninsular Florida) or we just have more lionfish here.
In 2015 there were again 28 derbies; 6 of those in the panhandle (21%). But only 10,953 lionfish were removed; 2,106 in the panhandle (19%). We did have a decrease in effort locally.
So why the decrease in effort?
Speaking with members of the Gulf Coast Lionfish Coalition – time and money. Coordinating and hosting derbies is time-consuming, and those who were volunteering their time were charter captains who forwent charters to do this… money. Everyone who has worked on lionfish since the 1980’s has commented that derbies have a lifespan. They are effective at removing large numbers of lionfish, especially if repeated often, but that they alone will not solve the problem.
So what now?
Well, here in Escambia county we are looking at the possibility of lionfish as a seafood product. At the Lionfish Removal and Awareness Day in Pensacola several local chefs’ tried different recipes with the public; one restaurant even offered smoked lionfish dip! The public seemed to like the fish but the cost of a fillet can be quite high. Publix offers a program called “Reel Variety” where you can order any fish you are interested in – lionfish is one, but the price ranges from $20-$30 / lb. Local divers in the Pensacola area are currently selling lionfish at prices bit lower but for the dip; fillets are still pricy. We will continue to experiment with this idea and see, if a low by-catch lionfish trap, can be developed and whether that will bring prices down. We are also monitoring for lionfish inside of our bays. In 2015 we can confirm two lionfish found inside Pensacola Pass in Big Lagoon; we will continue to monitor in 2016.
In Okaloosa County the Emerald Coast Reef Associationis working on a proposal that would reward those removing lionfish with permission to catch other regulated species out of season. We will see where 2016 takes us. The 2016 Lionfish Removal and Awareness Day will again be in downtown Pensacola May 14-15.
Red Lionfish are a predatory reef fish that are non-native invasive species and have spread throughout Florida Waters. They are members of the family Scorpaenidae whose members are venomous and the lionfish is no exception. This fish is relatively small ranging from 10-12 inches in length and have a zebra-like appearance with long, showy pectoral fins. They have a row of long dorsal spines that contain venom glands. Their native range is the South Pacific and Indian Oceans and preferred habitat is on offshore reef structures. These fish are considered to be voracious eaters feeding on native fish, reducing vital native populations, and competing for food with native fish such as grouper and snapper.
With few predators, these fish are thriving in Florida waters, even in the northern Gulf of Mexico. They reproduce often, under good conditions as often as every 3-4 days, with eggs hatching after about two days. They also consume a variety of local species. Research has found in some cases there has been an 80% decline in reef fish recruitment and loss of some economically important species. These fish are able to expand their stomachs for large meals and can survive starvation for over 12 weeks. Lionfish are an invasive species in our local waters and removal is encouraged.
The most effective control of this species is removal by spearfishing; though some recent reports of hook and line capture using live bait have occurred. Lionfish are cryptic and nocturnal but local divers have found them hovering near reefs at midday. Florida Fish and Wildlife Conservation Commission (FWC) changed regulations to increase harvesting opportunities. Such changes include no requirement for a recreational fishing license when using spearing devices (pole spear, a Hawaiian Sling, handheld net, or spearing devices marked for use on lionfish), and no recreational or commercial bag limit; though recreational fishing license is required for other fishing methods. Check the FWC regulations before fishing or diving for these species.
Lionfish are venomous, must be handled carefully, venom glands occur on the dorsal, pelvic and anal spines. Lionfish sightings can be reported at 877.786.7267, the newly released FWC lionfish app,or (if in the Pensacola area) the lionfish map. If stung the wound can be treated with warm (but not scalding) water. You may need to seek medical attention as soon as possible. Rarely are stings fatal unless the person has an allergic reaction. The Poison Help Hotline can be reached at 800.222.1222. Inshore sighting information is being collected by Florida Sea Grant in Escambia County to track the movement of these species. You can fill out the online report on the USGS website or the REEF website and stay up to date on research as it pertains to this species at the new NOAA lionfish portal and Florida Sea Grant.

From Fear to Fascination: White Sharks in the Florida Panhandle

Recently, I was walking on our local Gulf fishing pier checking fishing line recycle bins. You can’t walk on a Gulf pier without looking over to possibly catch a glimpse of a sea turtle or a shark, and I was not disappointed. It was hard to tell which species of shark but it was about 6 feet in length. It swam south along the edge of the pier and then east to make a large arching circle through the emerald water, past bathers at the surf break, and back to the pier only to swim the pattern again. Onlookers from out-of-town were giggling with delight to see the animal while a couple of local fishermen tried tossing bait at it, but most ignored it and went on with their fishing.
Bob Shipp’s book, Fishes of the Gulf of Mexico, lists 29 species of shark found locally. Most are members of the requiem shark family, such as blacktips and bulls, and hammerheads. Though these sharks are certainly capable of attacking humans, their presence usually does not interrupt water activities. Divers who encounter sharks may be startled at first but rarely do they end their dive or have problems with them. Even in 2005, remembered as the “summer of the shark attack”, few people stopped diving or surfing. Individuals have become educated regarding shark behavior and are not as startled when they see one. However, in 2015 there were several encounters with White Sharks.
Sightings in the Gulf of Mexico are rare but usually occur in the cooler months. Is the increased interaction with White Sharks unusual or something to worry about?
Burgess assured me that White Sharks do occur in the Gulf of Mexico usually during cooler months and are transients, as opposed to residents. Their movement in and out of the Gulf is temperature driven. As late spring Gulf waters continue to warm into early summer, sighting a White Shark is less likely to occur. According to Burgess, White Sharks use deep water when traveling but prefer shallow water when hunting fish, turtles, and marine mammals. So, inshore encounters especially in cooler months would not be unusual.
Why is there a sudden increase in the numbers of encounters?
One part of the answer lies with the increased number of White Sharks. Conservation of sharks has been effective. Additionally, with the passing of the Marine Mammal Protection Act, there are more marine mammals, thus an increase in their predators, White Sharks. The other part is the number of humans visiting the northern Gulf has increased. There are more more visitors to marine waters, especially since the Deepwater Horizon oil spill. Everyone has a camera. Beachgoers, Swimmers, Divers, and Anglers all have improved technology to record their adventures.
Is Northwest Florida a “hot spot” for White Sharks? Burgess indicated that the northern Gulf of Mexico is more productive than the peninsular Florida due to the number of nutrient rich rivers in the region. Seeing more White Sharks here would not be any more unusual than finding more snapper, lionfish, or other species of shark. As far as worrying, there have been no records of White Shark attacks in the northern Gulf of Mexico since they began keeping records in 1872.
Finally, what does one do if they encounter a White Shark?
The quick answer is nothing different than with any other shark. It is true that most White Shark attacks occur at the surface but there are no records of any attacks in Florida. Burgess indicated that the Bull Shark is probably a bigger threat than the White Shark. For more information about Bull Sharks and general tips to avoid a negative shark encounter read this articlehttps://nwdistrict.ifas.ufl.edu/nat/sharktips
In a recent video, recorded near Apalachicola, a diver was on an anchor line on a decompression stop when he saw a White Shark approaching from depth. What should a diver do in this situation? Should they swim for the surface and risk decompression sickness, remain still, or return to the bottom?
The answer has a lot to do with what the shark is actually doing. Is the shark interested in the diver or acting aggressively? Burgess suggests, you assess the situation and the shark’s behavior. All options are on the table and have to be weighed against the consequences given in this scenario. As a last resort, a diver may need to make a quick but graceful exit out of the water, past the shark, and depend on their diving partners to render aid as needed. The lesson is for divers to be prepared for a variety of potential issues on every dive.
We began our series on Nature Tourism along the ICW at the Alabama state line on Perdido Key and discussed the ICW itself. This month we will continue in Escambia County with a visit to Pensacola Beach.
The dune fields of panhandle barrier islands are awesome – some reaching over 50 ft. in height. This one is near the Big Sabine hike (notice white PVC markers).
The cannons of Ft. Pickens protected the entrance into Pensacola Bay. The views of the western end of Santa Rosa Island are great from here. There is plenty of nature and history to be discovered at this park. Plan to stay the day.
BARRIER ISLANDS
Pensacola Beach is on Santa Rosa Island. The longest barrier island in the panhandle, Santa Rosa Island stretches 44 miles from Ft. Pickens, at Pensacola Pass, to Destin Pass in Okaloosa County. With miles of some of the whitest beaches in the world, these panhandle islands have a variety of ecosystems. The mineral that makes the beach so white is quartz, one of the minerals found in granite rock. Over eons weathering and erosion has released these minerals from the granite in the Appalachians and sent it downstream to the Gulf coast. The densities of the different minerals force it to settle out at different rates. Quartz, being one of the less dense minerals, reaches the Gulf of Mexico where it encounters longshore currents. In the panhandle these currents more often run east to west moving the quartz in that direction. This sand forms bars and shallows which made colonial navigation a problem and good hiding places for pirates. Some of the bars remain above sea level and form dune fields and plant communities, forming barrier islands. Many animals, such as shorebirds and sea turtles, seek these islands for nesting because of few predators. The xeric conditions favor reptiles and birds, but there are many mammals and insects as well. Freshwater ponds form on many of the islands and here amphibians and fish came claim territory. The high energy beach of the Gulf side supports a community of subterranean organisms which include the mole crab (sand flea) and coquina. The low energy bay side harbors salt marshes along the shoreline and seagrass meadows below the surface. These habitats support a rich variety of marine life, some of the most productive in the world.
The Florida Trail extends (in sections) over 1,300 miles from Ft. Pickens to the Florida Everglades. It begins at this point.
PENSACOLA BEACH
There are many places on Pensacola Beach where visitors can enjoy these natural places. At the west end of the island is Ft. Pickens, part of the Gulf Islands National Seashore. Within the park you will find beaches to comb, piers to view wildlife and fish, jetties to fish or dive, fortifications to view the island, and a nice museum to educate you on both the natural and cultural history of the area. Here the Florida Trail begins. This trail is segmented and stretches from Ft. Pickens to the Everglades, but here it stops at Battery Langdon; it can be hiked or biked. Along the trail there are freshwater ponds and sections of maritime forest with a variety of wildlife viewing and photography. The multiple loop campground is found on this trail.
Between these pilings at Park West is one of the county snorkel reefs. Visibility is tough but the fish are there.
There is a kayak launch at Park West as well.
Just outside the entrance to the park is a county park named Park West. Here there is a kayak launch and nearshore snorkel reef on the bay side, with picnic area and beaches on the Gulf.
In Pensacola Beach proper there are several businesses that rent paddleboards for paddling the shallow seagrass filled Little Sabine. There are two marinas which offer sailing, fishing, and diving charters as well as dolphin tours. There are numerous artificial reefs off of Pensacola including the world’s largest – the U.S.S. Oriskany. On the Gulf side you will find the Pensacola Beach Fishing Pier where not only can you fish but, at times, see marine life. Sharks, sea turtles, dolphins, and large fish are often seen. The sunsets are great here. At the Visitors Center you can get a map to follow the Eco-Trail. This driving trail of 28 kiosks will take you to natural spots and the kiosks provide education about the area. There is a prize if you complete the trail.
Heading east from Pensacola Beach you once again pick up a portion of the Florida Trail. At this location there is a bike path, which can be walked or biked. Park East houses a popular nearshore snorkel reef. This snorkel reef is on the Gulf side and there are beach markers to help the diver locate it. On the bay side is Big Sabine. This area of high dunes and salt marsh has no formal trail but there are PVC pipes placed to help navigate your way in and out.
The paddleboard entry to Little Sabine can be found next to the Pensacola Beach Marina.
The Pensacola Beach Fishing Pier is not only a great spot to catch fish, it’s a great spot to see marine life – and great sunsets.
Further east you once again enter the Gulf Islands National Seashore. Escambia County is lucky to have almost 50% of their portion of the island within this national park. There are miles of natural beach to explore but you must use the public parking lots (no roadside parking) and watch your speed, this area supports several species of nesting shorebirds – some of which are listed as imperiled in the state of Florida.
The Santa Rosa island Authority’s Eco-Trail has 28 kiosk to navigate and learn about the natural history of the island. It is a fun and educational car trip. You can get the map for this trail at the visitors center on Pensacola Beach.

Next month – Santa Rosa County.
Aligning these markers will assist the snorkeler/diver in locating the Gulf snorkel reef at Park East. The swim is a bit further than Park West but the visibility is much better.
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.

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.
