易胜博官网鈥檚 commercial oyster farming industry is strong and growing, with the substantial growth potential to increase production, according to a researcher with the at the University of 易胜博官网.

According to new data released by the USDA in the 2017 Census of Agriculture, 易胜博官网 has 32 commercial mollusk operations representing $419,000 in sales. The commercial mollusk operations are in Strafford and Rockingham counties. 易胜博官网 Agricultural Experiment Station researcher Ray Grizzle, research professor of , says most of those commercial operations and sales represent oyster farming.

Working with existing and prospective farms as well as regulatory agencies, Grizzle began conducting research to expand the state鈥檚 oyster farming industry about 10 years ago. When he began, 易胜博官网 had only two licensed oyster farms. On average, it takes about three years to go from small 鈥渟eed鈥� oysters provided by hatcheries to market size, which creates a lag for oyster farmers beginning commercial production.

鈥淭he growth of oyster farming in the state is strong and likely to continue for quite some time. Overall oyster production is only a small fraction, perhaps 10 percent, of what it could be. The total number of farms and their areal coverage is probably nearing maximum for the Little Bay area, but production is not,鈥� Grizzle explains.

He points to data from 易胜博官网 Fish and Game to show the growth potential for the industry. In 2013, four 易胜博官网 farms together reported harvesting 81,274 oysters. Last year, 11 farms sold 439,497 oysters. However, there were 26 licensed oyster farm sites in the state in 2018, indicating that most have not begun to sell oysters yet.

鈥淢ost farms are still small with respect to production, some with just the owner doing all or most of the work. The ones that have been in existence for more than five years, however, have evolved substantially to include employees, improved farming methods and marketing networks that involve wholesalers as well as directly selling to local chefs. 易胜博官网 oysters are regularly featured at local raw bars and are shipped to other states in the region and elsewhere,鈥� Grizzle says.

Grizzle sees several opportunities to grow the state鈥檚 oyster farming industry, which will require farmers, regulatory agencies and those involved in marketing to work together. He says average annual production per farm is still quite low when compared to the more mature industries in Massachusetts and Maine. Thus, most growth in the near-term likely will come from individual farmers increasing their production.

鈥淭here may also be opportunities for expanding from bottom gear such as the commonly used 鈥榬acks-and-bags鈥� to surface gear or perhaps raft culture. This would allow farmers to move into deeper waters. Overall, the industry will hopefully evolve in a positive manner along with changes in farming methods, marketing opportunities and regulatory management,鈥� Grizzle says.

, owner of Row 34 in Portsmouth, has served local oysters at his restaurant since it opened in 2015. 鈥溡资げ┕偻� oyster farmers grow very high-quality oysters.听 As the water changes with the seasons, so does the flavor of the oysters.听It can be subtle or obvious. 易胜博官网 oysters have a great flavor that makes them different from oysters grown in other New England states,鈥� he says.听听

Sewall says the quality of 易胜博官网 oysters has improved in recent years as farmers have perfected their farming systems. 鈥淩ay is a pioneer in developing the oyster farms in 易胜博官网. Without him, 易胜博官网 would be years behind were it is in both quality of oysters and the benefit they bring to the water and the community,鈥� he adds.听鈥淕rowing food takes a lot of hard work and dedication. Supporting local fisheries and aquaculture is important to us.听By supporting them, we can keep locally grown food in our community and help the oyster farming industry. It is a big win for everyone, including the guests at our restaurant."

In addition to working to expand oyster farming, Grizzle and his team are looking at the role of oyster farms in providing 鈥渆cosystem services鈥� such as water filtration and habitat for other species. This recent research involved three 易胜博官网 farmers and several 易胜博官网 students and was supported by N.H. Sea Grant and the 易胜博官网 Agriculture Experiment Station.

Grizzle鈥檚 oyster research began 20 years ago with efforts to restore wild oysters. That early work, in partnership with the 易胜博官网 Departments of Environmental Services and Fish and Game, was experimental and small-scale. While it still is experimental, it has expanded in scale, now with each project typically involving a few acres. Recently, the restoration effort expanded to involve more oyster farmers thanks to funding from The Nature Conservancy and the USDA鈥檚 Natural Resources Conservation Service.

鈥淭he partnership of oyster farmers with those working on restoring wild oyster populations makes a lot of sense, and it has the potential to become an important win-win situation for all involved,鈥� he says.

According to The Nature Conservancy, in 易胜博官网 the听eastern oyster听has historically played a vital role in the ecology of Great Bay Estuary.听As many as 1,000 acres of live oyster reef may have covered the estuary in 1970, but more than 90 percent of oysters were lost due to pollution, harvest and disease. Without oysters, Great Bay Estuary is lacking the natural filtration capacity to maintain healthy eelgrass beds and fish nurseries as nitrogen and siltation increase.

易胜博官网 and The Nature Conservancy, together with other partners, have successfully restored more than 18 acres of reef and 3.5 million oysters to the system since 2009. In recent years, the team has scaled up efforts,听with as many as five acres and one million oysters restored annually.

鈥淭he oyster is, in many, ways a remarkable species. What other creature in our estuaries filters the water, builds large reefs that provide habitat for many other species, supports recreational and commercial fisheries, is now grown on farms throughout its range and tastes good?鈥� Grizzle says. 鈥淥yster farming is a rapidly growing industry in 易胜博官网, and it is occurring in one of the state鈥檚 most treasured waterways: The Great Bay estuarine system. Those interested in the economic as well as environmental health of the state should pay attention.鈥�
