Rutgers University signed an exclusive license that lets Atlantic Aqua Farms distribute diseaseresistant oyster broodstock to hatcheries and growers in Canada, the university’s Office for Research said Oct. 14. The announcement says 2026 is the first year Rutgers oyster seed was exported to Canada.
What the License Covers
The university’s announcement says the exclusive license gives Atlantic Aqua Farms, known as AAF, the right to distribute oyster broodstock that Rutgers developed. Broodstock are the adult oysters that hatcheries breed to produce seed, the young oysters growers raise to market size. The license covers distribution to hatcheries and farmers in Canada.
The announcement names three diseases: MSX, Dermo and Malpeque Disease. AAF says the MSX and Dermo crisis began in 2024. Malpeque Disease is endemic to Atlantic Canada. AAF’s goal is oysters that resist all three.
Meredith White, director of hatchery operations at AAF, said the company is excited to distribute the breeding materials to hatcheries in Prince Edward Island, Nova Scotia and New Brunswick. She said the seed from 2026 “performed extremely well thus far.” The announcement does not give survival or yield percentages, so it does not quantify that performance.
How MSX and Dermo Reached Canada
The Canadian Food Inspection Agency confirmed MSX and Dermo in samples from Spence Cove, New Brunswick, on Nov. 21, 2024, according to its statement. The agency called it the first confirmed case of MSX in New Brunswick and the first confirmed case of Dermo in Canada. Both diseases affect American oysters and cause higher mortality and slower growth. The agency said neither poses a risk to human health or food safety.
The agency confirmed Dermo in Egmont Bay, Prince Edward Island, on July 4, 2025, the first case on the island. It said Dermo spreads from oyster to oyster or through water contaminated with the parasite and does not affect mussels, scallops or clams. As of Sept. 2, 2025, the agency’s disease page lists Prince Edward Island, New Brunswick, Nova Scotia, Newfoundland and Labrador and Quebec as areas where both diseases are present or very likely present.
What Governments Have Spent
The Atlantic Canada Opportunities Agency announced a package for the industry on May 8, 2026, in a news release from Charlottetown. It says the Canadian Food Inspection Agency approved importing U.S. broodstock for disease-resistant oysters, with approval for seed expected within weeks, and that about $1.5 million is allocated for seed import approvals.
It adds more than $4.2 million to help Prince Edward Island growers buy disease-resistant seed and up to $6 million for a one-time buyback of affected wild oyster licenses. It also lists $130,000 for an industry strategy.
Since July 2024, Fisheries and Oceans Canada and the food inspection agency have run more than 17,000 diagnostic tests and invested $1 million in research, the release says. Peter Warris, executive director of the PEI Aquaculture Alliance, said the industry must shift from collecting natural seed to buying hatchery seed, and that the transition fund will help farmers cover the higher cost.
The Numbers in the Rutgers Announcements
AAF received orders for well over 50 million Rutgers-developed seed and exported more than 100 million to Prince Edward Island and New Brunswick, the Oct. 14 announcement says, and that still fell short of demand. A second Rutgers announcement dated Oct. 15 says the orders followed a CBC News report and that the company changed its hatchery operations to produce and export the larger volume. Neither announcement gives the period for the orders or the exports.
Canadian oyster aquaculture produced about 15,000 metric tons in 2023, valued at more than 66 million Canadian dollars, the Oct. 15 announcement says, attributing the figures to Fisheries and Oceans Canada. The release converts the value to about 46.59 million U.S. dollars. That works out to about 4,400 Canadian dollars a metric ton, or about 3,100 U.S. dollars, a calculation from the two figures.
A 2026 project imported triploid seed made from a Rutgers line called Haskin NEH and from Maine broodstock. The Oct. 14 announcement says the project offered hope to more than 50 growers in Prince Edward Island and New Brunswick, while the Oct. 15 announcement says more than 60. Triploid oysters make up more than half of global oyster production, according to the Oct. 14 announcement. Rutgers broodstock already accounts for more than 90% of the oyster seed in Maine.
The Breeding Work Behind the Seed
Ximing Guo, a Distinguished Professor in the Rutgers School of Environmental and Biological Sciences, has directed the university’s Shellfish Genetics and Breeding Program since 1998 and has worked with oysters since his undergraduate years in the 1980s. In 1993, Guo and Standish Allen invented tetraploid oysters at Rutgers’ Haskin Shellfish Research Laboratory. That was 33 years before the first Rutgers seed reached Canada, a count of the years between 1993 and 2026.
The Oct. 15 announcement says oysters have about 50% more genes than humans and that those genes are roughly 10 times more variable. Guo said in that announcement that “Canadian oyster farmers have suffered major losses from diseases,” and that the license lets AAF distribute Rutgers broodstock to them.
Deborah Perez Fernandez, executive director of the university’s technology transfer unit, said her office has worked with Guo for years, from patenting his inventions to commercializing them through licenses. Michael E. Zwick, the university’s senior vice president for research, said Rutgers research serves the common good of New Jersey and beyond.
What the Announcements Do Not Say
Neither announcement gives the license’s terms, such as its length or any payment to Rutgers. They do not name the number of Canadian hatcheries that will receive broodstock, and they report no field data on how many oysters survived on Canadian farms. They list no funding sources for the breeding work and quote no independent scientist or grower outside the university and AAF.
What Comes Next
AAF plans to evaluate seed made by crossing the Rutgers Haskin NEH line with oysters from Prince Edward Island in 2027, the announcements say. White said in the Oct. 15 announcement that the cross has the potential to produce seed resistant to all three diseases. Neither announcement lists a date for results from that evaluation.
