New Artificial Reefs for the Florida Panhandle

New Artificial Reefs for the Florida Panhandle

Deployment of the El Dorado as an Artificial Reef

Florida Fish and Wildlife crews also are pictured and assisted with the project from recovery through deployment. The 144 foot El Dorado reef is located 12 nautical miles south of St Andrew Pass at 29° 58.568 N, 85° 50.487 W. Photo by L. Scott Jackson.

In the past month, Bay County worked with fishing and diving groups as well as numerous volunteers to deploy two artificial reef projects; the El Dorado and the first of the Natural Resources Damage Assessment (NRDA) reefs.

These sites are in Florida waters but additional opportunities for red snapper fishing are available this year to anglers that book for hire charters with captains holding federal licenses. Federal licensed Gulf of Mexico charters started Red Snapper season June 1st and continue through August 1st. Recreational Red Snapper fishing for other vessels in State and Federal waters is June 11th – July 12th. So booking a federally licensed charter can add a few extra fish to your catch this year.

The conversion of the El Dorado from a storm impacted vessel to prized artificial reef is compelling. Hurricane Michael left the vessel aground in shallow waters. This was in a highly visible location close to Carl Grey Park and the Hathaway Bridge. The Bay County Board of County Commissioners (BOCC) acquired the El Dorado, January 14, 2019 through negotiations with vessel owner and agencies responsible for recovery of storm impacted vessels post Hurricane Michael.

The El Dorado was righted and stabilized, then transported to Panama City’s St Andrews Marina by Global Diving with support from the Coast Guard and Florida Fish and Wildlife. Hondo Enterprises, was awarded a contract to complete the preparation and deployment of the vessel for use as an artificial reef.

Reefing the El Dorado provides new recreational opportunities for our residents and tourists. The new reef delivers support for Bay County’s fishing and diving charters continuing to recover after Hurricane Michael. Several local dive charter captains assisted in the towing and sinking of the El Dorado.

The El Dorado was deployed approximately 12 nm south of St. Andrew Bay near the DuPont Bridge Spans May 2, 2019. Ocean depth in this area is 102 feet, meaning the deployed vessel is accessible to divers at 60 feet below the surface.

The Bay County Board of County Commissioners continues to invest in the county’s artificial reef program just as before Hurricane Michael. Additional reef projects are planned for 2019 – 2020 utilizing Natural Resources Damage Assessment (NRDA) and Resources and Ecosystems Sustainability, Tourist Opportunities, and Revived Economies of the Gulf Coast States Act (RESTORE Act) funds. These additional projects total over 1.3 million dollars utilizing fines as a result of the Deepwater Horizon Oil Spill. Deployments will occur in state waters in sites located to both the east and west of St. Andrew Bay Pass.

The first of these NRDA deployments for Bay County BOCC was completed May 21, 2019 in partnership with Mexico Beach Artificial Reef Association, Florida Fish and Wildlife Conservation Commission, and Florida Department of Environmental Protection using a $120,000 portion of the total funding. The deployment site in the Sherman Artificial Reef Permit Area is approximately 12 nm south east of St Andrew Bay Pass at a depth of 78 – 80ft.

In 2014, Dr. Bill Huth from the University of West Florida, estimated in Bay County the total artificial reef related fishing and diving economic impact was 1,936 jobs, $131.98 million in economic output and provided $49.02 million in income. Bay County ranked #8 statewide in artificial reef jobs from fishing and diving. Bay County ranked #3 in scuba diving economy and scuba diving was 48.4 % of the total jobs related to artificial reefs. Dr. Huth also determine that large vessels were the preferred type of artificial reef for fishing and diving, with bridge spans and material the next most popular. Scuba diving and fishing on artificial reefs contributes significantly to the county’s economic health.

Declaration of Fishery Resource Disaster Update for Hurricane Michael (as of November 23, 2018)

Declaration of Fishery Resource Disaster Update for Hurricane Michael (as of November 23, 2018)

Fishery Disaster damage to marina docks and vessels after Hurricane Michael.

There was a special Fishery Disaster declaration post-Hurricane Michael. Here is an example of the damage to marinas and vessels that service our local fisheries. Unseen is the economic damage to fishing crews and supporting shore base businesses such as seafood processors, bait and tackle shops, and tourism related businesses. (Photo by Allen Golden).

Florida Governor Scott requested Fishery Disaster Assistance because of Hurricane Michael October 23, and the US Secretary of Commerce official responded with a determination letter providing additional disaster assistance to impacted fishing businesses and individuals October 31, 2018. https://www.commerce.gov/news/press-releases/2018/11/us-secretary-commerce-wilbur-ross-declares-fishery-disaster-florida

This link provides an outline for the established process to obtain Fishery Disaster Assistance: https://www.fisheries.noaa.gov/insight/frequent-questions-fishery-disaster-assistance

Additional Hurricane Michael relief funds and resources for local fisheries are welcome and encouraging. However, there are several steps before these specific program funds will be available. After the Secretary of Commerce sends the Florida Governor a determination letter, there are additional steps before those funds will reach the industry.  The timing of these specific fisheries disaster resources varies; Hurricane Irma (2017) funds have not made it through the entire process at this time. A funding plan for Irma was recently developed by the state of Florida in September 2018. http://myfwc.com/conservation/special-initiatives/irma

Other disaster recovery programs, including those for Hurricane Michael, can be accessed now by fishing and coastal businesses. There is a helpful document written to help guide fishermen to other recovery resources with examples of how fishing businesses accessed some of these program funds. See more at https://www.fisheries.noaa.gov/webdam/download/66759294

One important immediate aid program to consider is the Florida Small Business Development Center ‘bridge” loan program. Solo proprietors can borrow $25,000 while businesses with paid employees can qualify for up to $50,000 for one year interest free. This program is meant to provide immediate dollars to assist business owners while they await other payments from insurance or federal assistance such as the Small Business Administration loan. Important Deadline: Applications will be accepted through December 7, 2018. Learn more about the Florida SBDC Bridge Loan program at http://www.floridadisasterloan.org

Federal Small Business Administration Disaster Loan Program is a long term loan to aid in business or personal recovery. https://disasterloan.sba.gov/ela/Documents/Three_Step_Process_SBA_Disaster_Loans.pdf

Business Recovery Centers (BRC) provide one on one counseling and assistance from both the Florida SBDC and US SBA to help individuals navigate the recovery process. The current location of the Hurricane Michael Business Recovery Centers is available at: http://floridasbdc.org/services/business-continuation/disaster/

The Florida SBDC also has permanent offices throughout Florida. Visit http://floridasbdc.org/locations/ to find a location near you.

If you need additional information assistance for your marina, commercial fishing, or for-hire charter business related to Hurricane Michael, please contact your local UF/IFAS Extension Office and Florida Sea Grant Extension Agent.

Hurricane Michael Devastates Regional Seafood Industry

Hurricane Michael Devastates Regional Seafood Industry

Erik Lovestrand, UF/IFAS Franklin County Extension

It may be a long time before the memories of Hurricane Michael begin to fade in the mind’s eye for residents of the Florida Panhandle. A record-breaking tropical cyclone in many respects, Michael caught a lot of people in the region off guard as it continued to gain strength on its rapid path through the Northern Gulf of Mexico. When many people went to bed the night before landfall, they had no idea what terrifying news would greet them upon hearing that a still-strengthening category 4 hurricane was about to rumble ashore.

It was not long after the wind slackened that folks began looking around and realizing the devastation left behind. Cotton crops in the path of the storm in North Florida and South Georgia suffered near 100% losses. Peanut crops were also severely impacted just at the time that harvest was beginning. The estimated damage to timber harvests alone were coming in around 1.3 billion dollars for Florida as virtually entire forests had been leveled. Even more damage was realized near the coastline where storm surge across the region ranged from 8 to 14 feet above normal water levels; smashing or flooding structures near the coast and carving new inlets across St. Joseph Peninsula near Cape San Blas.

Another industry that took a hard hit in much of the area was the seafood industry; everything from the producers to the dealers, processors, retail markets, restaurants, fueling and ice house facilities that service fishing vessels. Governor Scott requested a fisheries disaster declaration from the Federal Government and on November 1 the Secretary of the Department of Commerce granted the request. This determination provides an opportunity for Congress to appropriate fishery disaster assistance for the new fiscal year, which began in October. To further facilitate recovery efforts in Florida and beyond, the Department of Commerce can look to the Economic Development Administration, which spearheads the Federal government’s efforts to deliver economic assistance and support long-term growth after natural disasters.

Oyster growers in the region who had equipment and a crop of shellfish in the water took some losses as well. For those who were able to scramble to their leases before the storm and sink their floating baskets or cages to the bay bottoms, losses of gear were minimal as storm waves above the submerged gear had less impact. Gear that was unable to be submerged was more prone to break loose and drift away. However, even the growers that sunk gear experienced some significant oyster mortality due to sediments from churned up water smothering the shellfish in a layer of mud. Shellfish leases in Alligator Harbor were dealt another blow by an incredible field of debris that was washed off Alligator Point and blown through the lease area. Everything from boats to large sections of docks, structural walls, refrigerators and freezers was in the mix. These items were caught up in oyster long-lines and broke some while pulling up anchor poles on others, leaving quite a mess for growers to untangle.

Marinas, docks and vessels were also not immune to Hurricane Michael’s wrath in Gulf and Bay Counties. Government agencies estimate the number of damaged vessels in both Gulf and Bay counties to exceed 400. It will take some time for charter boat and commercial fishing operations to rebound. Scallop restoration projects in both St. Joseph Bay and St. Andrews Bay have suffered setbacks, as well. The hurricane has not only devastated coastal Gulf county economically and ecologically, but also geographically. There are two sizable inlets that have now been carved into the St. Joseph Peninsula. T.H. Stone State Park is closed until further notice.

Overall, the impacts from this storm will take a long time to recover from for many segments of our regional economy. Lessons learned by industries as well as individuals should improve our chances to reduce the loss of life and property in the future. The name of the game is “resiliency,” both in the spirit of the people who call this place home and in the way we learn to better adapt to what Mother Nature throws at us. Hang in there. Day by day.

What’s Up with the Red Tide in the Panhandle?

What’s Up with the Red Tide in the Panhandle?

Red Tide has been a persistent presence in the Panhandle since September and responsible for many reported fish kills and respiratory distress in some people.  Over the past week, red tide was still present in low to medium concentrations in or offshore of Escambia County to Bay County.

This is a picture of a dead 4-inch striped Jack-knife fish, killed by red tide, laying next to a clump of sargassum on the beach in Miramar Beach, Florida.

Red tide is a natural occurrence and Florida experienced red tides long before humans settled here.  The tides originate 10-40 miles off shore and winds and currents bring them inshore.  Red tide is fueled by nutrient typically stemming from land-based runoff.

During winter, the northerly winds and southbound currents will push the tide back offshore.  There was hope that Hurricane Michael might help carry the red tide back out to sea. Unfortunately, it seems the nutrient run-off from the storm’s heavy rain or retreating storm surge may have contributed to the intensity and duration of the bloom.

In our economy, which is heavily dependent on tourism, the red tide is continuing to take a toll, especially on waterfront businesses.  According to the Florida Fish and Wildlife Conservation Commission, store-bought and restaurant served shellfish are safe to eat during a red tide bloom because shellfish are monitored for safety and tested for red tide toxins before they are sold. The edible parts of crabs, shrimp and fish are not affected by the red tide organism and can be eaten, but guts should be discarded.

Many remember the local red tide bloom in 2015.  The longest red tide bloom ever recorded lasted 30 months from 1994 to 1997.  Warmer water due to climate change is predicted to cause algae to bloom more often, more intensely, and in more water bodies. It is imperative that we reduce nutrient inputs to our lakes, rivers, estuaries and coastal ocean waters today.

Nature Notes – The Blue Crab

Nature Notes – The Blue Crab

Most kids who grew up on the Gulf Coast grew up catching blue crabs. These animals are common along our shorelines, relatively easy to catch, and adventurous because they may bite you.  I caught my first one in 1965 and we proudly displayed the boiled shell over the kitchen bar for many years.  This is also a popular seafood target with an estimated commercial landing value of $56,950 in the Pensacola Bay area in 2017.

But who is this crab that we enjoy so much? What do we know about it?

 

As you probably already know, it is one of an estimated 30,000 species of arthropods we call crustaceans.  Crustaceans differ from insects and arachnids in that they have five pairs of legs and two sets of antenna.  Insects typically have a head, thorax, and abdomen – however, in the crustaceans the head and thorax are fused into what is called a cephlathorax and covered with a section of the shell called the carapace.  Like all arthropods, their body are completely covered in a chitinous shell that serves as their exoskeleton.  This exoskeleton must be periodically shed (molting) so they can continue to grow.  Crustaceans tend to molt about 10-11 times each year and typically in the summer months.  To molt, crustaceans will remove some of the salts and minerals from the shell into their tissue, this weakens the shell enough to separate it.  The crack is usually between the cephlathorax and abdomen.  When they emerge, they are completely soft and about 30% larger than before – it is amazing to see this large crab emerge from the small shell it once lived in.  Because of the softness of the body after molting, this is usually done under the cover of darkness for protection.  The salts and minerals it removed during pre-molting are now used to harden the new shell – which can take a couple of days.  It is at this stage we call them “soft shells”.

 

The crustaceans include many different kinds of arthropods – most notably are the crabs, shrimps, and lobsters. There are over 4500 species of crabs and they differ from shrimps and lobsters in the fact their abdomen flexes beneath their body – you do not see the “tail” you see in a lobster or shrimp – but its there.  Crabs can also move very well laterally, which their cousins are not so good.  Blue crabs differ from other crabs in that their last pair of legs are modified as paddles and the animal can swim.  They can swim forwards, backwards, and laterally – and they are often seen swimming at the surface.  There are other crabs who have these swimming paddles and they are all called protunid crabs.

 

Blue crabs perceive their world through their eyes, antenna, and sensory cells on their body. They are very good at burying in the sand – eyes and antenna exposed – and sensory cells all working – seeking prey and avoiding predators.  Their eyes differ from ours in that they have numerous lenses, compared to our single one, and are called compound eyes.  Each lens does not provide them with an image of you or me however.  Rather each lenses provides them with a single pixel of light.  It is much like the image you see on television when they are trying to block out a brand name, or someone’s face.  The more pixels (lenses) you have, the clearer the image.  Those this type of eye does not give as clear an image as ours; it is very good at detecting motion and has served the arthropods very well over the years.

 

For blue crabs, food can be just about anything. They are active hunters – usually using the ambush method of capture (buried in the sand), but are also known scavengers – eating any bits of food they can find.  Those enjoy crabbing know this – you can put just about anything as bait in a crab trap and it works.  They have numerous predators including fish, birds, mammals, and sea turtles.

Blue crabs can be found in a variety of salinities (euryhaline). Males are typically found in the lower salinities of the upper bay.  Females join them during mating season – which is in late spring and summer.  Males cradle the females beneath his legs for several days waiting for the right location and moment to breed.  Fishermen refer to them as “doublers” during this time.  The females will molt and the male will then deposit his sperm into a sac called a spermatophore – which he then deposits to the female.  She will then migrate to the more saline lower portions of the lower bay, while he remains and seeks another female.  This may be the only spermatophore she receives her entire life – which can be up to five years, though most do not live beyond three years.  She will use sperm from this spermatophore over that time to fertilize eggs.

 

The eggs develop in a sponge mass that develops beneath her abdomen. This egg mass is orange when in early development and becomes a darker brown with age as the larvae consume the yolk.  There can be between 750,000 and 2,000,000 developing eggs within this mass.  The females are called gravid at this stage and it is illegal to harvest gravid crabs in Florida.

 

The eggs hatch in about two weeks and a small microscopic mosquito looking larvae emerges – at this stage, they are called zoea.  The zoea drift into the Gulf of Mexico where they feed and molt.  Eventually they return to the estuary and become a microscopic crab with a tail – this stage is called a megalops.  The megalops will feed and molt.  The tail will eventually flex beneath and the crab becomes sexually mature.  The entire process from hatching to sexual maturity is about 12-18 months.

 

These are fascinating animals. They are very common and a large part of the coastal culture of the Florida panhandle.  Kids will have great fun catching them with a hand net, letting them swim in their beach buckets, but be sure to let them go before you head home and watch those claws – they do know how to use them.  It is a great animal.

Researchers Test Traps for Controlling Deepwater Invasive Lionfish

Researchers Test Traps for Controlling Deepwater Invasive Lionfish

It’s early morning as Dreadknot Charters speeds out of Destin Harbor towards the offshore reefs in the Gulf of Mexico. Researchers Holden Harris (Graduate Research Fellow, University of Florida), Alex Fogg, (Marine Resource Coordinator, Okaloosa County), and the Dreadknot crew, Josh and Joe Livingston, ready their equipment on board. They’re working on a new method of capturing invasive lionfish: deepwater traps.

Red lionfish (Pterois volitas / P. miles) are a popular aquarium fish with striking red and white strips and graceful, butterfly-like fins. Native to the Indo-Pacific region, lionfish were introduced into the wild in the mid-1980s, likely from the release of pet lionfish into the coastal waters of SE Florida. In the early 2000s lionfish spread throughout the US eastern seaboard and into the Caribbean, before reaching the northern Gulf of Mexico in 2010. Today, lionfish densities in the northern Gulf are higher than anywhere else in their invaded range.

Invasive lionfish negatively affect native reef communities. They consume and compete with native reef fish, including economically important snappers and groupers. Their presence has shown to drive declines in native species and diversity. Lionfish possess 18 venomous spines that appear to deter native predators. The interaction of invasive lionfish with other reef stressors – including ocean acidification, overfishing, and pollution – is of concern to scientists.

Lionfish harvest by recreational and commercial divers is currently the best means of controlling their densities and minimizing their ecological impacts. Lionfish specific spearfishing tournaments have proven successful in removing large amounts in a relatively short amount of time. This year’s Lionfish Removal and Awareness Day removed almost 15,000 lionfish from the Northwest Florida waters in just two days. Lionfish is considered to be an excellent quality seafood, and they are now being targeted by a handful of commercial divers. Several Florida restaurants, seafood markets, and grocery stores chains are now regularly serving lionfish.

While diver removals can control localized lionfish densities, the problem is that lionfish also inhabit reefs much deeper than those that can be accessed by SCUBA divers. Surveys of deepwater reefs show lionfish have higher densities and larger body sizes than lionfish on shallower reefs. In the Gulf of Mexico, the highest densities of lionfish surveyed were between 150 – 300 feet. While SCUBA diving is typically limited to less than 130 feet, lionfish have been observed deeper than 1000 feet.

For the past several years, researchers have been working to develop a trap that may be able to harvest lionfish from deep water. Dr. Steve Gittings, Chief Scientist for the Office of National Marine Sanctuaries at the National Oceanic and Atmospheric Administration, has spearheaded the design for a “non-containment” lionfish trap. The design works to “bait” lionfish by offering a structure that attracts them. The trap remains open while deployed on the sea floor, allowing fish to move in and out of the trap footprint. When the trap is retrieved, a netting is pulled up around

the fish inside and they are brought to the surface.

The researchers are headed offshore to retrieve, redeploy, and collect data on the lionfish traps. Twelve non-containment traps are currently being tested offshore NW Florida. The research is supported by a grant from the Florida Fish and Wildlife Conservation Commission. The study will try to answer important questions for a new method of catching lionfish: where and how can the traps be most effective? How long should they be deployed? And, is there any bycatch (accidental catch of other species)?

Recent trials have proved successful in attracting lionfish to the trap with minimal bycatch. Continued research will hone the trap design and assess how deployment and retrieval methods may increase their effectiveness. If successful in testing, lionfish traps may become permitted for use by commercial and recreational fisherman. The traps could become a key tool in our quest to control this invasive species and may even generate income while protecting the deepwater environment.
