Chesapeake Bay Oysters Spawn Sustainability Efforts
In partnership with: Virginia Department of Agriculture and Consumer Services
Beneath the waters of the Chesapeake Bay lie some of the Virginia’s most important aquaculture products. While the ecosystem is vastly different, the farming practices are similar to those on land.
Cherrystone Aqua-Farms is a fifth-generation, family-owned-and-operated clam and oyster farm on the Eastern Shore. The company prides itself on innovation and forward-thinking despite its centuries-old heritage.
“Our primary focus is implementing sustainable farming and harvesting practices to cultivate hard clams and several oyster brands of Eastern oysters,” says Tim Rapine, managing director for Cherrystone Aqua-Farms. “We’re the largest producer on the East Coast with an annual sales volume of around 100 million clams, and we account for over 25% of Virginia’s annual oyster sales.”
The company produces clams and oysters through a vertically integrated system, spawning the shellfish with their own broodstock lines in hatcheries.
“We do spawn out of season by controlling environmental factors like water quality, temperatures and food availability to help ensure the health and growth of the baby oysters and clams, as well as emulating the natural growth process,” Rapine says.
The shellfish are then grown in the same open waters as their wild counterparts in put-and-take fisheries.

Sustainable Shellfish
The Chesapeake Bay used to be home to a vast number of wild oysters and shellfish but has suffered some environmental decline in the past several decades.
Shellfish farming in the Bay actually improves water quality, as a single adult oyster can purge up to 50 gallons of water per day. It reduces harvest pressure on wild stocks while increasing the overall number of shellfish to help clean the waters.
“The key distinction between farming and natural growth lies in the degree of control over the environmental conditions,” Rapine says. “Clam and oyster farming not only ensures a consistent, sustainable supply but also contributes to conservation of wild populations by reducing harvesting pressures.”
Despite the previous environmental decline, Rapine says there’s been a notable resurgence in the population of shellfish in the Chesapeake Bay in recent years, significantly impacting Virginia’s economy, communities and aquaculture industry. Positive results include improved water quality and ecosystem health, economic opportunities for fishers, growth within the sector, and an enhanced commitment to environmental stewardship.
“The resurgence of oysters and other shellfish in the Chesapeake Bay represents a multifaceted boom for Virginia,” Rapine says. “This positive trend not only supports the livelihoods of those directly involved but also contributes to the overall vitality of Virginia’s coastal communities and economy.”
