The Florida Fish & Wildlife Conservation Commission and UF/IFAS Extension – Florida Sea Grant have partnered to implement an innovative community-driven effort to restore scallop populations, and we need your help! “Scallop Sitter” volunteers are trained to assist in Bay, Gulf and Franklin Counties. The goal of the program is to increase scallop populations in our local bays. Scallop sitters help reintroduce scallops into suitable areas from which they have disappeared.
Volunteers manage predator exclusion cages of scallops, which are either placed in the bay or by a dock. The cages provide a safe environment for the scallops to live and reproduce, and in turn repopulate the bays. Volunteers make monthly visits from June until December to their assigned cages where they clean scallops (algal and barnacles can attach), check mortality rate and collect salinity data that helps us determine restoration goals and success in targeted areas.

*We know issues happen from time to time with scallop populations. It’s a bummer. If you loose a significant amount of scallops early in this year’s program, we will do our best to accommodate our volunteers with a “second wave” scallop stocking event in August. Also, looking for other ways to help our program? We plan to offer cage building workshops in the fall, stay tuned!
We used to find them here. I have heard stories of folks who could fill a 5-gallon bucket with them in about 30 minutes right by Morgan Park. An old shrimper told me that back in the day when shrimping in Santa Rosa Sound they often found scallops along the points. They would drop a grab and collect them for sale. This was when both commercial scallop harvest, and shrimping, were allowed in Santa Rosa Sound. Neither are today. There are numerous tales of large beds of scallops in Big Lagoon and scientific reports of their presence in both locations and in Little Sabine. I myself have found them at Naval Live Oaks, Shoreline Park, Big Sabine, and in Big Lagoon.

But that was a long time ago. The reports suggest the decline began in the 1960s and today it is rare to find one. What happen is hard to say but most believe it began with a decline in water quality. A decrease in salinity and an increase in nutrients from stormwater runoff degraded the environment for both the scallops and the turtle seagrass they depend on. Overharvesting certainly played a role.
But they are not all gone. There is still turtle grass in our system and occasionally reports of scallops. They are trying to hang on. There have also been attempts to improve water quality by modifying how stormwater is discharged into our bay, though there is much more to do there. Each year Florida Sea Grant Agents at our local county extension offices provide volunteers an opportunity to survey our bay for both species. We have a program called “Eyes on Seagrass” where volunteers monitor sites with seagrass once a month from April through October. We partner with Dr. Jane Caffrey from the University of West Florida to assess this. We also hold our annual “Pensacola Bay Scallop Search” each July.
In the Scallop Search volunteers will snorkel four different 50-meter transects lines either in Santa Rosa Sound or Big Lagoon searching for scallops. These surveys are conducted at the end of July. There are 11 survey grids in Big Lagoon and 55 in Santa Rosa Sound extending from Gulf Breeze to Navarre. To volunteer you will need a team of at least three people and your own snorkel gear. Some locations do require a boat to access. If you are interested in searching along the north shore of Santa Rosa Sound contact Chris Verlinde at chrismv@ufl.edu (850-623-3868). If you are interested in searching along the south shore of Santa Rosa Sound, or Big Lagoon, contact Rick O’Connor at roc1@ufl.edu (850-475-5230).

Reminder, harvesting scallops in Escambia and Santa Rosa counties is still illegal. Please give them a chance to recover.
The local Community Collaborative Rain, Hail, and Snow network is seeking interested citizen scientists to participate in the collecting weather data. See the notice below from local coordinator, Larry McDonald, for more information:

Weather forecasting depends on taking readings and measurements from the atmosphere. And it’s not just professionals, like meteorologists, who measure rainfall, temperatures, and humidity levels. You can, too! The Community Collaborative Rain, Hail, and Snow network (CoCoRaHS) allows everyday citizens to participate in weather data collection by measuring daily precipitation/rainfall totals at their own homes or workplaces. Using a special rain gauge that provides great detail in detecting rain amounts, CoCoRaHS observers submit rain observations online to a national network… along with over 20,000 participants in the U.S., Canada, and the Bahamas. Precipitation amounts are then evaluated for many needs by national, regional, and local weather forecasters, researchers, drought and flood monitoring, and agricultural interests. Rainfall data submitted can also be used in forecasting to predict the possibility of flash flooding for local flood prone areas.
A CoCoRaHS observer simply needs to purchase the approved rain gauge (costing from $30 to $40), mount the gauge in an open area away from roofs, fences, and vegetation, and simply collect rain that falls directly from the sky over a 24-hour period. Once each day, between 5:30 AM and 9:00 AM, the gauge is checked for rain with the amount recorded and submitted to the CoCoRaHS website. Missing a day or more is okay, but the more you report, the better the overall data becomes for your area. New and active CoCoRaHS observers are needed throughout Escambia and Santa Rosa Counties.
Those interested in possibly joining CoCoRaHS as an observer can obtain more information by visiting https://cocorahs.org/. You can also contact the CoCoRaHS local volunteer coordinator for Escambia and Santa Rosa Counties by emailing escambia_fl_cocorahs@icloud.com
Back in the spring, I wrote an article about the natural history of this ancient animal. However, Florida Fish and Wildlife Conservation Commission (FWC) is interested in the status of horseshoe crabs and they need to know locations where they are breeding – and Florida Sea Grant is trying to help.

If you are not familiar with the horseshoe crab, it is a bizarre looking creature. At first glance, you might mistake it for a stingray. It has the same basic shape and a long spine for a tail. But further observation you would realize it is not a stingray at all.
So then… What is it?
When you find one, most are not comfortable with the idea of picking it up to look closer. The spine is probably dangerous and there are numerous smaller spines on the body. Actually, the long spine in the tail region is not dangerous. It is called a telson and is most often used by the animal to push through the environment when needed, as well as righting itself when upside down. It is on a ball-and-socket joint and if you pick them up, they will swing it around – albeit slowly – but it is of no danger. Note though, do not pick them up by the telson – this can damage them.
If you do try to pick them up with your hands on their sides, you will find they are well armored and have numerous clawed legs on the bottom side. At first, you are thinking it is a crab, and the claws are going to pinch, but again we would be mistaken. The claws are quite harmless – they even tickle when handled. I have held them to allow kids to place their hands in there to feel this. However, when held they will bend their abdomen between 90° and 120°, as if attempting to roll into a ball – which they cannot. At this point, they become difficult to hold. Your hands feel they are in the way and the small spines on the side of the abdomen begin to pierce your skin. So, you flip it on its back. It begins to try a 90° bend in the other direction and begins to swing the telson around. This is probably the most comfortable position for you to hold – but I am not sure what the crab thinks about it.
So, what do you have?
Well, you can see why they call it a crab. It has clawed legs and a hard shell. The body is very segmented. You can also see why it is called a “horseshoe”. But actually, it is not a crab.
Crabs are crustaceans. Crustaceans have two body segments – a head and abdomen, no middle thorax as found on insects. This is the case with the horse crab as well.
Crustaceans have 10-segmented legs, though the claw (cheliped) and swimming paddles (swimmerets) of the blue crab count as “segmented legs”. Horseshoe crabs have 10 as well – seems this IS a crab – but wait…
Crustaceans have two sets of antenna – two short ones and two long – horseshoe crabs do not have any antenna. Traditionally biologists have divided arthropods into two subphyla – those with antenna and those without – so the horseshoe crab is not a crab. It is actually more closely related to spiders, ticks, and scorpions.

It is an ancient animal, fossil horseshoe crabs in this form date back over 440 million years – out dating the dinosaurs. There are four different species of today and there probably were more species in the past. Their range extends from the tropics and temperate coastlines of the planet. Today three of the remaining four species live in Southeast Asia. The fourth, Limulus polyphemus, lives along the eastern and Gulf coast of the United States.
Unfortunately, this neat and ancient creature is becoming rare in some parts of its range. There is a commercial harvest for them. Their blood is actually blue and contains properties beneficially in medicine. Smaller ones are used as bait in the eel fishery, and there is always the classic loss of habitat. These are estuarine creatures and are often found in seagrass and muddy bottom habitats where they forage on bottom dwelling (benthic) animals.
FWC is interested in where horseshoe crabs still breed in our state. Some Sea Grant Agents in the panhandle are assisting by working with locals to report sightings. Sea Grant also has a citizen scientist tagging program to help assess their status. Horseshoe crabs typically breed in the spring and fall during the new and full moons. On those days, they are most likely to lay their eggs along the shoreline during the high tide. This month the full moon is October 5 and the new moon is October 19. We ask locals who live along the coast to search for breeding pairs on October 4-6 and October 18-20 during high tides. If you find breeding pairs, or better yet, animals along the beach laying eggs – please contact your local Sea Grant Agent. We will conduct these surveys in the spring and fall of 2018 and post best search dates at that time.
