¿Está interesado en hacer algo que beneficie a su comunidad marina local? ¡Disfruta de días al sol, como un “Scallop Sitter” (cuidador de las vieiras)!
“Scallop Sitters” (cuidador de vieiras) es uno de nuestros programas de voluntariado cooperativo con Pesca y Vida Silvestre de Florida (FWC, por sus siglas en inglés). Históricamente, las poblaciones de vieiras de la bahía eran muy numerosas y podían sustentar las pesquerías en muchas bahías del norte de Florida, incluidas la bahía de San Andrés, la bahía de San Juan y el Puerto de los Caimanes (Condado de Franklin). Años consecutivos de malas condiciones ambientales, pérdida de hábitat y “mala suerte” en general resultaron en una escasa producción anual y provocaron el cierre de la pesquería de vieiras. La vieira de la bahía es una especie de corta vida que pasa de ser una cría a adultos que desovan y muere en un año aproximadamente. Las poblaciones de vieiras pueden recuperarse rápidamente cuando las condiciones de crecimiento son buenas y pueden disminuir drásticamente cuando las condiciones de crecimiento son malas.
En 2011 se presentó la oportunidad de poner en marcha la restauración de las vieiras de la bahía del norte de Florida. Con la financiación del derrame de petróleo de Deepwater Horizon, se propuso un programa de restauración de vieiras en varios condados, que finalmente se estableció en 2016. Los científicos de Pesca y Vida Silvestre de Florida (FWC, por sus siglas en inglés) utilizan vieiras criadas en criaderos, obtenidos a partir de progenitores o reproductores de las bahías locales, para cultivarlas en masa y aumentar el número de adultos reproductores cerca del hábitat crítico de las praderas marinas.
La Pesca y Vida Silvestre de Florida (FWC, por sus siglas en inglés) también creó otro programa en el que los voluntarios pueden ayudar con la restauración llamado “Scallop Sitters” en 2018 e invitó a UF/IFAS Extension a ayudar a dirigir la parte de voluntarios del programa en 2019, lo que llevó a esfuerzos específicos en los condados del Golfo y la Bahía.
Para ayudar a las vieiras, los “Scallop Sitters” trabajan con UF/IFAS Extension, Florida Sea Grant y los científicos de restauración de la Pesca y Vida Silvestre de Florida (FWC, por sus siglas en inglés) limpiando las vieiras y comprobando la salinidad una vez al mes desde junio hasta enero.

Después del hiato de 2020 debido a COVID-19, el programa presumió de casi 100 voluntarios para la campaña de 2021. UF/IFAS Extension se asocia de nuevo con Pesca y Vida Silvestre de Florida (FWC, por sus siglas en inglés) en los Condados de Bahía y Golfo y Franklin. A pesar de los retos que suponen las lluvias, la escorrentía de las aguas pluviales y la baja salinidad, nuestros voluntarios de Scallop Sitter han proporcionado información valiosa a los investigadores y a los esfuerzos de restauración, especialmente en estos primeros años de nuestro programa. Los “Scallop Sitters” recogen información útil sobre la salinidad en las bahías de destino. Pero la mayor parte del impacto se produce al observar de cerca sus vieiras. Las vieiras que mantienen sus cuidadores tienen más posibilidades de desovar con éxito cuando sea el momento adecuado.

¿Qué hace un cuidador de vieiras? Los voluntarios dirigen jaulas de exclusión de depredadores de vieiras, que quedan colocadas en la bahía o junto a un muelle. Los “Scallop Sitters” (cuidador de vieiras) vigilan la tasa de mortalidad y recogen datos sobre la salinidad que ayudan a determinar los objetivos de restauración y el éxito en las zonas seleccionadas.

Scallops…
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.
Bay scallops need turtle grass to survive.

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).

Recently I watched a documentary on TV entitled The Loneliest Whale; the search for 52. The title grabbed my attention and so, I checked it out.
There are many forms of wildlife that are very hard to find in our area. But we continue to look.

Seems a decade or so ago the U.S. Navy was doing SONAR work in the Pacific between Washington and Alaska and detected a strange sound coming in at 52 hertz. They had not herd this before and would continue to hear it in different locations around the northern Pacific. Their first concern was it was something new from the Russians, but when they showed the graphs and played the recording to a marine mammologist named Dr. Watkins, they found that it was most likely a “biological” – mostly likely a whale.
The problem was that Dr. Watkins had never heard whales calling at 52 hertz. If it was a whale, it was calling a lot – but no other whales were answering. Hence the name “the loneliest whale”. If it was a whale, and no others would talk to it, it was kind of sad. But who was this whale? What kind was it?
Word of the loneliest whale spread around the world and many humans made a connection to this animal, possibly because of their own disconnect with their own species. Stories and ballads were written, and people began to feel for the poor animal that apparently had no friends.
This story caught the attention of a documentary film maker who was interested in finding “52”, as the whale became known. He solicited the help of other marine mammologists; Dr. Watkins had died. According to those marine mammologists, this was going to be VERY difficult. It is hard enough to find just a pod of whales in the open Pacific, much less a specific pod with a specific individual. But they were excited about the challenge of finding this one animal, “52”, and off they went.
As I was watching this documentary it reminded me of my own search here near Pensacola. In 2005, I was asked by members of state turtle groups if I could search to see if diamondback terrapins lived in the western panhandle. This turtle’s range is from Cape Cod Massachusetts to Brownsville Texas, but there were no records from the Florida panhandle. Did the animal exist there? I was running the marine science program at Washington High School at the time and thought this would be a good project for us. So, we began.

The students researched terrapin biology and ecology to determine the locations with the highest probability of finding, and we searched. I quickly found that the best time to search for terrapins was during nesting in May and June, and that the worst time to do a project with high school seniors was May and June. So, the project fell on my wife and me. For two years we searched all the “good spots” and found nothing. We placed “Wanted Poster’s” at boat ramps near the good spots with only calls about other species of turtles, not the terrapin.
Then one day in a call came in from a construction worker. Said he had seen the turtle we were looking for. For over a year we had been chasing “false calls” of terrapins. So, I was not overly excited thinking this would be another box turtle or slider. I asked a few questions about what he was looking at and he responded with “you’re the guy who put the wanted poster up correct? – well your turtle is standing next to the poster… it’s the same turtle”. Now I was excited. We did some surveys in that area and in 2007 saw our first terrapin! I can’t tell you how exciting it was. Two years of searching… at times thinking we might work on another project with a different species that actually exists… reading that the diamondback terrapin is like the Loch Ness monster – everyone talks about them, but no one has ever seen one. And there it was, a track in the sand and a head in the water. Yes Virginia… terrapins do exist in the Florida panhandle. The excitement of finding one was indescribable.
We were hooked. We now had to look in other counties in the panhandle, and yes, we found them. As I watched the program of the marine mammologists searching for “52” I could completely relate.
Today, as a marine educator with Florida Sea Grant, I train others how to do terrapin surveys and searches. I let them know how hard it is to find them and to not get disappointed. When they do see one, it will be a very exciting and fulfilling day. Our citizen science program has expanded to searching for other elusive creatures in our bay area. Bay scallops, which are all but gone however we do find evidence of their existence and spend time each year searching for them. In the five years we have been searching we have found only one live scallop, but we are sure they are there. We find their cleaned shells on public boat ramps – by the way, it is illegal to harvest bay scallops in the Pensacola Bay area. Another we are searching for is the nesting beaches of the horseshoe crabs. This is another animal that basically disappeared from our waters but are occasionally seen now. It is exciting to find one, but we are still after their nesting beaches and the chase is on.

I love the challenge of searching for such creatures. If you do as well, we have a citizen science program that does so. You can just contact me at the Escambia County Extension Office to get on the training list, trainings occur in March, and we will get you out there searching. As for whether they found “52”, you will have to watch the program 😊

Can you remember where you were one year ago last April? The uncertainty of each day seemed to go on forever. At this time last year, we were planning several education programs that eventually had to be canceled or migrated to online events. Scallop Sitters was one of our cooperative volunteer programs with Florida Fish and Wildlife (FWC) that was postponed during the pandemic in 2020. Thankfully, FWC biologists continued restoration work last year in the region with good results and steps forward. However, there was something painfully absent in these efforts – you!
One of the lessons last year taught us, is to appreciate our opportunities – whether it is to be with your family, friends, or serve your community freely through volunteer service. Some new service opportunities appeared while others were placed on hold. Thankfully, we are excited to announce the Scallop Sitters Citizen Scientist Restoration Program is returning to our area in St. Andrew, St. Joe, and Apalachicola Bays this summer!
Historically, populations of bay scallops were in large numbers and able to support fisheries across many North Florida bays, including St Andrew Bay. Consecutive years of poor environmental conditions, habitat loss, and general “bad luck” resulted in poor annual scallop production and caused the scallop fishery to close. Bay scallops are a short-lived species growing from babies to spawning adults and dying in about a year. Populations can recover quickly when growing conditions are good and can be decimated when conditions are bad.
An opportunity to jump start restoration of North Florida’s bay scallops came in 2011. Using funding as a result of the Deepwater Horizon Oil Spill, a multi-county scallop restoration program was proposed and eventually established in 2016. Scientists with FWC use hatchery reared scallops obtained from parents or broodstock from local bays to grow them in mass to help increase the number of spawning adults near critical seagrass habitat.
FWC also created another program where volunteers can help with restoration called “Scallop Sitters” in 2018 and invited UF/IFAS Extension to help manage the volunteer portion of the program in 2019 which led to targeted efforts in Gulf and Bay Counties.
After a year’s hiatus, UF/IFAS Extension is partnering with FWC again in Bay and Gulf Counties and expanding the program into Franklin County. Despite initial challenges with rainfall, stormwater runoff, and low salinity, our Scallop Sitter volunteers have provided valuable information to researchers and restoration efforts, especially in these beginning years of the program.
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 January to their assigned cages where they clean scallops removing attached barnacles and other potential problem organisms. Scallop Sitters monitor the mortality rate and collect salinity data which determines restoration goals and success in targeted areas.

Many people enjoy scallops. Just as many enjoy scalloping.
It is a great Florida family activity where everyone gets to snorkel in relatively shallow – safe waters. You explore the grassbeds for a myriad of cool marine creatures yelling across the bay to friends about all the neat things you are seeing.

And of course, there are the scallops. Sitting on top of the grass blades with their undulated ridged shells and ice blue eyes. You reach to grab one and they begin the “clap” their shells together to escape being captured. You finish the adventurous day with your limit of scallops, and it is time to eat – broiled in butter and some seasoning is my favorite.
It is great fun. However, it is becoming harder to find them.
Once found in grassbeds from Pensacola to Miami, the recreational harvest has been restricted to the Big Bend area – the commercial no longer happens. Everywhere their numbers are down and many locations within their historic range, you cannot even find them. Since 2015, Florida Sea Grant has conducted scallop searches in the Pensacola Bay area using citizen volunteers and have found only one live animal. We have found numerous shells of these creatures, who only live a year… maybe two. We have had reports of live scallops in the bay area outside of our formal search dates, I have personally found some, but the numbers are still very low – low enough that recreational harvesting in the Pensacola Bay area is closed indefinitely.
The story is the same from south of the Big Bend. Scallop searches are conducted every year and returns are low, or non-existent. So, the focus turns the Big Bend.
They are famous for the scallop seasons. Floridians travel from all neighboring counties, and from across the state, to partake in this fun activity. It is good business for these local communities. For some, it is the biggest money maker of the year. However, now we are hearing stories of low harvest numbers in some parts of the Big Bend. In recent years, Port St. Joe Bay has suffered from algal blooms and red tide that not only closed the waters to harvesting for swimming safety reasons, but because the scallop numbers declined as well. One story out of Hernando County indicated that the numbers in this region are now down. You must consider overharvesting as a problem as well.
Prepared properly: One of the finest meals you will ever have.
FWC is interested in restoring these animals to parts of their range where they were once common. The Scallop Sitters program is one where volunteers can hang caged scallops raised in state hatcheries from their docks, protected from predators, and allow them to mass spawn. The first pilot project in our area was in Bay and Gulf counties… last year… when Hurricane Michael came through. Obviously, they will have to start over.
What is needed to extend this project into other bay areas?
Well, you certainly do not want to put them into waters where you know they will die. The scallop populations declined for a reason – primarily habitat loss and overharvesting. Excessive stormwater runoff decreased much needed salinity and increased grass killing turbidity. Loss of seagrass equates to loss of scallops. Florida Sea Grant is currently working with the University of West Florida, and citizen volunteers, to monitor seagrass growth and density in Santa Rosa Sound and Big Lagoon. We will have a report on this year’s work later this fall. We are also working with citizen scientists monitoring salinity in these bodies of water hoping for a mean of 20 parts per thousand or better. We will have the summer salinity reports out at the end of September. We hope these data will support the argument of extending the scallop sitters program further west.

But there is the question of overharvesting.
In recent years we have found evidence of locals in the Pensacola Bay area illegally harvesting the few scallops we have. Some residents do not know that it is illegal to harvest in these waters – it is – and the only way we can successfully restore them, is allow them to mass spawn. To do this, we need large numbers.
Each year Florida Sea Grant conducts the Great Scallop Search in the Pensacola Bay area. We also host a “Bio-Scavenger Hunt” in the fall where scallops are one of the target species.
