More than 100 million oyster seed bred from Rutgers University stock were produced and shipped to growers in Prince Edward Island and New Brunswick this year, the first time seed from the New Jersey program has gone to Canada. The shipments came after two oyster diseases, MSX and Dermo, began devastating Atlantic Canadian farms in 2024. Rutgers announced the work this week alongside an exclusive licensing deal with a Prince Edward Island shellfish company.

Demand outran supply even at that scale. The company that raised the seed received orders for more than 50 million Rutgers-developed seed after a news report on the shortage, and still could not fill every request. For farmers who watched whole crops die, the arrival of disease-resistant stock was less a technical milestone than a lifeline.
MSX, Dermo and the 2024 crisis
According to a Rutgers announcement distributed through Newswise, the crisis that began in 2024 stems from MSX and Dermo, two parasitic diseases, and Rutgers’ Haskin NEH strains are resistant to both. The strains come from the shellfish genetics and breeding program that Ximing Guo, a Distinguished Professor in the School of Environmental and Biological Sciences, has directed since 1998. Atlantic Canada also has its own native threat, Malpeque Disease, and the goal is hybrid seed resistant to all three.
The 2026 project produced triploid seed, sterile oysters that grow faster and have strong summer meat quality, using Haskin NEH and Maine broodstock. Triploids account for more than half of all farmed oysters worldwide. More than 60 growers in Prince Edward Island and New Brunswick were helped by the effort. Guo, whose Rutgers profile details his career, traces the technology to 1993, when he and Standish Allen invented tetraploid oysters carrying four sets of chromosomes at the university’s Haskin Shellfish Research Laboratory.
Oysters are an unusually good subject for selective breeding. The announcement notes that they have been farmed for more than 2,000 years, dating back to ancient Rome, that they carry about 50 percent more genes than humans, and that their genes are roughly ten times more variable. Guo began studying oysters as an undergraduate in the 1980s, and the National Shellfisheries Association has named him an honored life member for the career that followed.
The license with Atlantic Aqua Farms
The legal piece is an exclusive licensing agreement between Rutgers and Atlantic Aqua Farms, a North American shellfish producer based in Prince Edward Island. The company runs hatcheries, nurseries and growing grounds in Atlantic Canada and Maine, has a presence in Virginia, and operates its central U.S. distribution facility in Eliot, Maine. Rutgers’ Office for Research executed the deal through its Technology Transfer unit, and the license lets the company distribute Rutgers-developed broodstock, the adult oysters used to produce seed, in Canada.
Meredith White, director of hatchery operations at Atlantic Aqua Farms, is among the people quoted in the announcement, along with Deborah Perez Fernandez, executive director of Technology Transfer, and Michael Zwick, senior vice president for research at Rutgers. The company plans to distribute the breeding materials to hatcheries in Prince Edward Island, Nova Scotia and New Brunswick. In 2027 it plans to evaluate seed from Haskin NEH oysters crossed with local Prince Edward Island oysters.
What is at stake for Canadian oyster farms
Canadian oyster farming produced about 15,000 metric tons in 2023, valued at more than 66 million Canadian dollars, roughly 46.59 million U.S. dollars, according to the release’s citation of Fisheries and Oceans Canada statistics. Those figures show how much was riding on the seed supply when disease struck. The release adds that Rutgers broodstock already supplies more than 90 percent of the oyster seed in Maine, so the arrangement extends a model that has worked across the border. The 2026 season was the first in which Rutgers strain seed was exported to Canada, and the planned 2027 evaluation of Haskin NEH crossed with local Prince Edward Island oysters is aimed at hybrid seed that resists MSX, Dermo and Malpeque Disease together.
The news report that prompted the surge in orders came from the CBC, whose coverage of Prince Edward Island oyster seed imports is cited in the announcement. Seed shortages persist, because supply still fell short of demand even after more than 100 million seed were exported. The Haskin Shellfish Research Laboratory, in Port Norris, New Jersey, is part of Rutgers and the New Jersey Agricultural Experiment Station, where the breeding work behind the exported seed was done. The lab runs four facilities in southern New Jersey, including a Bivalve Laboratory, a Cape Shore Laboratory and an Aquaculture Innovation Center, and describes its mission as being dedicated to research, education and extension in support of sustainable shellfish and finfish resources. Its outreach programs include aquaculture internships and a Regional Shellfish Seed Biosecurity Program, a reminder that seed health is as much a logistics question as a breeding one.
