Nature has provided us with an incredible resource in the diverse assemblage of molluscan shellfish that inhabit our coastal bays and estuaries. One bivalve species in particular provides many human benefits. The eastern oyster (Crassostrea virginica) has not only proven to be a preferred food species for people but also derives many vital ecosystem services through its existence in our near-shore estuaries. Oysters are born as planktonic larvae that drift in the water for about 2 weeks. They are called a spat when they settle out of the water column and glue themselves to a suitable hard surface, such as another oyster shell, and begin to grow their own shell. Oysters feed on particulates in the water throughout their life and when mature can filter as much as 50 gallons per day. Because of this life style they provide some degree of water purification and improvement in water clarity. The structure of an oyster reef is also a valuable habitat component which provides shelter for a plethora of small creatures that support a vast food web in the estuary ecosystem.

Barges will also be used to relay shells for replenishing oyster habitat.
Although we have several native species of oysters in the Gulf of Mexico the eastern oyster is the only species that supports a commercial industry. in Florida, the bulk of that industry has traditionally been centered around Apalachicola Bay in the mid-Panhandle region of the state. This one estuary system typically produces 90 percent of the state’s oyster crop and 10-13 percent of the nation’s harvest. Some good harvest years have yielded 4-6 million pounds of oyster meat (shells excluded) from this single bay. In recent years however there has been a dramatic decline in oyster abundance. The industry, along with concerned natural resource managers, is seeking to rebuild numbers to a sustainable harvest level. The reasons for this precipitous drop in numbers is the subject of much debate but savvy natural resource professionals believe a combination of factors have been involved over several years to cause the current situation.
Fossil oyster shell being relayed to bay bottom.
So, how do you bring back a thriving oyster industry from the brink of collapse? Several factors need to be considered and addressed as part of a holistic management approach. At the present time there are two primary mechanisms being employed to support increased oyster recruitment to Apalachicola Bay. The first involves “planting” a suitable material on the bay bottom for oyster spat attachment and growth. In the past this has primarily consisted of oyster shells from the shucking plants. More recently the industry has been employing the use of fossil shell material from a local mine. Oystermen are being employed to transfer the shell from land-based loading areas to the designated deposition sites in the bay. Funding is also forthcoming to allow shelling by barges to cover more area. The other strategy to assist with recovery has involved the use of regulatory authority in consultation with local experts and oystermen with decades of experience on the bay. This approach can reduce the harvest pressure on oysters and support a more rapid recovery, given proper conditions in the estuary. Bag limits have been reduced, enforcement has been stepped up to ensure compliance with the rules, and harvest areas have been adjusted.
Oystermen line up early to receive shell for relay project.
There are, of course, other important aspects to the solution for bringing back the thriving industry of the past and many of them relate to natural cycles of drought and flooding. Increasing human demands for water from the river system that feeds the bay tend to magnify the effects of natural drought cycles. If salinity remains high for longer periods there is an increased pressure from oyster predators that typically are limited by lower salinity. Factors related to oyster diseases and parasites are also in the mix. To say that it is a complicated situation would be an understatement. Researchers who have studied the system for their entire careers find it difficult to quantify the problems and solutions for this large, complex natural ecosystem that has been an important cultural and economic component of Florida’s makeup since early humans roasted or cracked open the first oyster. Hopefully, with enough concerned partners working towards effective management strategies we can once again enjoy in abundance the wholesome, delicate morsels that have been called the food of the gods.
Beginning this month we will be posting a series of natural resource articles high lighting Florida’s Panhandle. The photographs and hikes presented in this series are from Escambia and Santa Rosa counties but the same natural places can be found anywhere between the Perdido and Apalachicola Rivers. We hope our readers will visit these places and DISCOVER FLORIDA’S PANHANDLE on their own. This year we will begin at the Gulf of Mexico and visit our BARRIER ISLANDS. We will visit the same location on Santa Rosa Island in Escambia County each month over the course of a year. During this series we should see how things change each season and learn more about our natural places.

Here is the Gulf of Mexico. The northern Gulf is primary sand but their are areas of hard bottom that provide habitat for many of our commercial important fisheries. 450 feet off the shore from this photo is an artificial reef placed by Escambia County for residents and visitors alike to explore. These reefs attract a variety of reef fish and sea turtles and are great for wildlife viewing. Notice how low the sun is in the sky on this winter morning. The shortest day of the year was December 21 (when the sun was it’s lowest) and will be “climbing” as this series continues. Many beach residents use this as their clock!
Our barrier islands are considered the “world’s whitest beaches” and this is because of the high amount of quartz deposited here. In this photograph you can see the water is farther from shore than usual. This is due to the strong north winds blowing water offshore; this happens every winter – but provides feeding opportunities for shorebirds. The sand fencing is used by many of our counties to “kick start” dune restoration.

Beyond the primary dune on this portion of the island you will find low areas known as swales. These “depressions” will fill with water during rain events and provide much needed freshwater for the organisms who live out here. Barrier islands are xeric environments (meaning “desert like”) and freshwater habitats are very important for many creatures. Some of these ponds are ephemeral (meaning non-permanent) and dry up during some periods of the year.

The water in most swales is freshwater. Photo: Rick O’Connor
Where the primary dune and swales end the secondary dune fields begin. Because of the primary dunes there is less wind and salt spray which allows different species to take root. The secondary dunes are often identified by their small round shrubs – such as goldenrod and beach heather. These larger plants will trap larger amounts of sand producing larger dunes. On the secondary dunes I usually find lots of tracks. Identifying tracks is difficult (especially in soft sand) but fun. Most of what I saw this winter day were mammals. Raccoons, opossums, and armadillos are very common. Skunks were once common but have been scarce since the hurricane years. Below are tracks of a canine. Many people bring their dogs to the beach but coyote and fox are also found here. These tracks measured about 3.5″ and more round than triangle shaped; suggesting this is a dog.

This secondary dune supports a saw palmetto. Many forms of wildlife depending on these shrub areas.
These unidentified canine tracks are probably of a dog; though coyotes are on our islands
Beyond the secondary dunes are the largest dunes on the island, some measuring over 50′, these are the tertiary dunes. With the secondary dunes blocking wind and salt spray larger plants still are allowed to grow. Here we find actually trees; pine, live oak, magnolia to name a few. With the loss of primary and secondary dunes the tertiary dunes are exposed to the wind and salt spray of the Gulf side, which puts them at risk. This is why sea oats and primary dunes are protected in most counties.

Tertiary dunes are the largest dunes on the island; some reaching over 50′.
Tertiary dunes support trees such as this magnolia and yaupon holly.
The large field of tertiary dunes blocks enough wind that forests and salt marshes can establish themselves on the back side of the island. Here the diversity and abundance of wildlife increases. We have found not only the mammals already mentioned but snakes, freshwater turtles and terrapins, and a variety of birds. This winter day I found several small woodland and mocking birds. Some of our islands have deer and alligators.
From atop a tertiary dune you can view the maritime forest, salt marsh, and sound beyond. Photo: Rick O’Connor
Within the maritime forest you will find a variety of plants and animals.
Holly’s are famous for having the bright red berries around Christmas time. Here in January the berries are still found on some of them.
Between the maritime forest and the salt marsh you may find freshwater ponds. Like the swale ponds, these places are great places to find wildlife. Though I have not seen them in many years I have found alligators in this area. These ponds support populations of amphibians and small fishes.

With the dunes blocking offshore winds trees can grow much larger on the back side of the island; like this live oak.
This pond supports a stand of green algae which supports many of the aquatic animals that visit here.
On this winter day I primarily saw bird life. The air temperature was 39 F and the wind was out of the north. Many of the mammals move at night and the reptiles, being cold blooded, were hibernating somewhere; the bird life however was pretty active. Many woodlands birds were out feeding on seeds and berries, herons and egrets were in the marsh hunting fish in the shallow waters, and shorebirds were picking through the beach wrack and some were diving.

This unusual drag was found between the salt marsh and the sound side shoreline. It looks like a turtle crawl but at his time of year more probable something being dragged by something.
Armadillo tracks can be identified by their “tail drags”.
Salt marshes are one of the most productive systems on earth; and the target for another FLORIDA’S PANHANDLE series. Crabs, shrimp, mollusk, worms, terrapins, fish, and birds are some of the wildlife that call this place home – and maybe we will find some as this series continues into the warmer months. Today I found pelicans, herons, and egrets here eating.

The muck of a salt marsh. This rich organic mud is very loose and the hiker can quickly sink! Notice the tracks of a predator.
Notice the low water levels typical of winter. This congregates fish into smaller pools and makes it easier for birds and mammals to catch them.
The Sound side of the island has wind but less wind than the Gulf side. The wave energy here is also lower supporting seagrass and oyster communities. Like the marsh these places are very productive; though all I really saw moving on this cold winter morning were the birds. There are two species of seagrass common to our sounds; turtle grass and shoal grass. However there have been reports of more tropical species appearing. We may find some when the water warms up. These waters support at least 100 species of fish and many invertebrates we enjoy eating.
The darker areas in the water are seagrasses. Photo: Rick O’Connor
I found this along the shore last winter. These are cannonball jellyfish.
This is a sea nettle. This species of jellyfish has a more painful sting. I only saw one of these today but saw several cannonballs.
People find this “sea foam” frequently when they visit the beach. It is formed when the winds pick up and there are nutrients in the water. It was up and down the beach today.
It is not uncommon to find dead fish along the shore after a hard freeze as we have had in recent weeks. When it warms these dead fish will attract scavengers including cottonmouths. Maybe we will see one later in the year.
There was very little trash on the island today but it was there. These pieces of debris can cause serious problems for coastal wildlife. We will discuss this issue more as this series moves on.
Well, for January we found the beach to be cold and windy. Very little wildlife was out to be viewed other than birds and the numerous tracks in the dunes, but as the temperatures warm we will see more. Take some time to visit our barrier islands and enjoy them. Until February.

The selection of Dr. W. Kent Fuchs (pronounced “Fox”) as the next president of the University of Florida should be cause for celebration for anyone who cares about Florida agriculture and natural resources.
I’ll confess, I had some initial apprehension about whether an electrical engineer would be properly attuned to the importance of UF’s land-grant mission.
But I had the chance to take the measure of the man one-on-one over a 21Ž2-hour dinner as part of UF’s efforts to recruit top leaders to apply for the presidency, and I’m convinced he will support university research, extension and teaching that improve the lives of all Floridians. I endorse Fuchs, who still has to be confirmed by the State University System Board of Governors.
Fuchs was born into a hardscrabble existence on an Oklahoma farm. It was such a tough life that his dad decided Alaska would be more forgiving, and it’s where Fuchs grew up until the family moved to Miami, where he attended high school.
And let’s remember, he’s provost at one of the most venerable of land-grant universities, Cornell. It’s the only Ivy League school with a horticultural department, much less a School of Integrative Plant Science like the one Fuchs helped launch. Before Cornell, he was a leader at Purdue, also a land-grant university, and taught and researched at a third, the University of Illinois Urbana-Champaign.
With his Florida, agriculture, and land-grant bona fides, he sold me on being the right person for the job when he told me that if hired he would go on a statewide tour of stakeholder meetings. Not just to meet donors and alumni, but growers, commodity leaders, natural resource managers and UF/IFAS Extension agents.
That’s a promising sign that he intends to honor the public-service ethic of the land-grant university. He sees his new job the same way I see mine — that his office is not a room in Gainesville, but it’s the entire state. He’s walking the walk in New York with the recently announced Engaged Cornell, a $150 million initiative that aims to institutionalize a mandatory public-service component in undergraduate education so students contribute to solving problems outside the university gates.
UF’s land-grant mission is supposed to apply university wide. Traditionally, though, UF’s Institute of Food and Agricultural Sciences has more demonstrably implemented it than many other branches of the university.
There’s potential for real change in this area as our medical center leaders see in Extension the opportunity to do so much more to promote public health. Similarly, our engineering administrators have approached IFAS about working through Extension to bring technical assistance to businesses and communities.
There are also opportunities for IFAS to do more to serve Florida’s $142-billion-a-year agriculture and natural resource industries, particularly after six years of flat or declining state funding.
Support from UF’s leader is essential to IFAS’s quest to provide solutions to citrus greening, efforts to tackle the state’s water quality and water supply challenges, ambitious plans to expand the work of our agricultural leadership institute and work in helping Florida prepare for climate change and sea-level rise.
The land-grant system was founded more than 150 years ago on the noble proposition of democratizing higher education.
Today we have an opportunity to define the 21st century land-grant institution that is true to its mission while responding to the pressing problems of today.
Today IFAS seeks support from the UF administration to expand four-year online degree programs. We offer these at a discounted tuition to students who by choice or circumstance need a UF education to come to them instead of having to move to Gainesville.
Appalled by anecdotes of students going hungry or even scrounging from garbage bins, we at IFAS have begun formally assessing the extent of food security on campus as the first step toward establishing a food pantry for students in need. We’re hiring more bilingual 4-H agents and partnering with organizations that serve minority populations as we seek to better serve people who have traditionally been underrepresented in our youth development programs.
It’ll take a commitment from the top to secure the resources needed to realize IFAS’s potential. That commitment starts with an appreciation of the land-grant mission. Fuchs has looked me in the eye and shown me he has it.
Over salad, I began probing the extent to which this man intended to honor the land-grant mission with action. By decafs and dessert, I was presenting him with the Gator pin right off my own lapel and letting him know he’d be receiving a copy of A Land Remembered from me.
The presidential search committee on which I served declared a strong academic background an essential criteria for our next leader. The distinguished research background Fuchs has and his Ivy League experience more than satisfy that.
Some of us on the search committee – which also included IFAS plant breeder Harry Klee — also championed an appreciation for the land-grant mission as an important consideration in the search for a new president. We’re gratified to see we have it in Kent Fuchs, and we hope you’ll get to see it when he visits your region.

The commercial and recreation stone crab season has opened! Now is the time to enjoy local stone crab claws. Whether you catch them yourself or buy from a local seafood market, the delicious meat is worth the effort and cost.
There are 2 species of stone crab found along the Gulf Coast. The Florida Stone Crab is found in the southern part of the state, while the Gulf stone crab is found from the Western Panhandle to Mexico.
Stone crabs can be found in holes along oyster reefs, rock jetties and shorelines lined with riprap. Adult stone crabs feed on oysters, mussels, clams, worms and other crustaceans.
Recreational harvesters must have a valid Florida Saltwater Fishing licence and are limited to 5 traps that meet the specifications set by FWC. Maximum trap size is 2″x2″x2″ and traps must have a degradable panel that is 5 ½ inches by 3 ½ inches and is made of cypress or untreated pine slat no thicker than ¾ of an inch. These regulations are to protect marine life from ghost fishing, when traps are abandoned or lost.
The recreational bag limit is one gallon of claws per person or 2 gallons per vessel or which ever is less. Only one crab claw should be taken. Crabs are released alive with one claw intact and are able to feed and defend themselves, which allows the crab to be caught again in the future. The claw that was removed will grow back each time the crab molts. Claws must be 2 3/4 inches in length from the tip of the claws to the first knuckle.

Watch the following video from FWC to learn how to harvest a claw correctly without injuring the crab.
Stone crab claws can be enjoyed cold or hot, in the shell or peeled and in many different dishes. Enjoy stone crab claw meat with mustard dipping sauce, in soup and bisque, crab cakes, salads, etc. Many recipes can found on-line.
Use a butter knife, mallet, claw cracker or hard spoon to crack the shells. If you want to prevent shell from flying around, cover the hand that will hold the claw or the surface that the claw will be cracked on with a dish towel. Gently tap the sections of the claws, until they are cracked, be careful not to break the shell into the meat.
Check out this video to learn how to crack stone crab claws:
