PORT REPUBLIC — New Jersey shellfish farmers from Tuckerton to Mantoloking are getting paid to foster oysters for conservation alongside market oysters sold in seafood restaurants through a $961,227 award from the U.S. Department of Agriculture - Natural Resources Conservation Service’s Regional Conservation Partnership Program.
The RCPP funds private and public partnerships for conservation; in this case, contributing to the restoration of rare and declining natural communities of oysters.
Kristin Adams, a 2017 Stockton University graduate who studied oysters as a graduate student, was awarded the grant to involve commercial growers in the restoration of the bay. The oysters that grow up on commercial leases will move to two restoration reefs monitored by Stockton’s Marine Field Station.
Adams is a conservation and aquaculture specialist for the Ocean County Soil Conservation District and a U.S. Department of Agriculture Natural Resources Conservation Service partner. She brought Stockton on board to help monitor changes in water quality and to sample marine life on and off the participating oyster leases with seine and gill nets.
Adams first studied biodiversity surrounding oyster farms in Barnegat Bay as a Professional Science Master’s graduate student.
She sees bivalves as a beacon of hope for bringing back a healthy bay ecosystem with their ability to filter water and provide habitat.
Stockton/A close up look at spat on oyster shells. The red hashes mark the tiny spat that attached themselves to oyster shells to grow.The four-year pilot project began this year with nine farmers fostering baby oysters, known as spat, from June through November. The spat are currently growing on shells in floating mesh bags or bottom trays in the bay.
Baby oysters grow by sticking themselves to a hard substrate.
The spat-on-shell method gives oysters a head start. The larvae grow up in tanks on land that are filled with shell. Once the larvae stick to the shell, they are moved to the oyster leases to grow up in the bay.
“For most of the producers, spat-on-shell is new. They are used to growing the single cocktail oyster for raw bars where they use single oyster seed to grow a beautiful, tasty product for restaurants. This is a different technique and gives producers with smaller leases a way to farm for restoration,” Adams said.
In late November, the farmers will plant the foster oysters on two conservation reef sites, the Mill Creek Reef and the Tuckerton Reef.
As a Soil District employee, Adams works with private landowners to implement conservation practices such as no till, creating pollinator habitat and managing forests.
Growing up on Long Beach Island, the saltwater is Adams’ second home, and that knowledge of the bay has extended her work into the water. The oyster is her strategic partner in promoting sustainability and helping to improve the health of the bay ecosystem.
Seven years after graduating, oysters brought Adams back to the Marine Field Station.
This August, she joined Christine Thompson, associate professor of Marine Science, and student researchers Landon Gedes and Samantha Gransee to monitor water quality and sample biodiversity with a seine net at an oyster lease in Great Bay.

“Stockton’s role is documenting the ecosystem services at four of the oyster farm sites and then long-term monitoring at the reef sites,” she added.
On a warm summer day, wearing full wetsuits to ward off greenheads, the team jumped into the bay to pull a seine net along the submerged bags of oysters.
The creatures caught were emptied into a holding tank on the R/V Rudy Arndt to be identified, weighed, measured and then released.
The star of the show was a seahorse that blended in with a clump of brown macro-algae. Comb jellies and Atlantic silversides were the most abundant catches, and a tautog and pipefish were other species represented.
Bottles were filled with 100-mL water samples at the lease and control site to be studied back in the lab.
“We are looking to see if the water is clearer on the reef sites. Last year, some of the areas surrounding the Tuckerton Reef were significantly clearer than the control and that’s indicative of the filtration capacity. And you can see it,” Thompson said.
Dale Parsons Jr., a fifth-generation shellfish farmer, calls the opportunity a “win-win-win-win.”
When he was growing up, restoration was unheard of, but now it’s a necessity. He noted the project educates farmers, restores habitat and equips growers with the spat-on-shell growing method that offers a noncompetitive revenue stream for a product that is not sellable on the seafood market.
Federal dollars are coming into New Jersey and giving farmers a way to sell oysters that are less than a year old, too small for restaurants, but full of filtering and habitat potential when planted on a conservation reef.
“There are few opportunities where oyster farmers can work together,” Parsons explained, but conservation is a team effort, and the grant project is looking to reach enough farmers to make a difference in the bay.
“It's not for my immediate benefit. It's for generations down the road, whether it be my daughter or someone else's children, if they decide they would like to venture out to the bay to experience what it is to produce income from a limited resource, they're going to have a place to work,” Parsons said.
The impact of the project is measurable. Parsons calls Stockton the “biological auditors” who are answering the questions. “What are the improvements? How efficient is this? What can we learn from the monitoring data,” he asked.
Parsons has been involved in Stockton’s oyster conservation efforts since the creation of the Tuckerton Reef in 2017.
“There were no oysters in the bay for a number of decades due to disease pressure. Now we have an oyster that is resistant to the diseases, and we have the opportunity to use that oyster to produce a habitat that would extend this resource much more than it normally would,” Parsons said.
