Genetically modified salmon head to US dinner plates

May 28, 2021 — The inaugural harvest of genetically modified salmon began this week after the pandemic delayed the sale of the first such altered animal to be cleared for human consumption in the United States, company officials said.

Several tons of salmon, engineered by biotech company AquaBounty Technologies Inc., will now head to restaurants and away-from-home dining services — where labeling as genetically engineered is not required — in the Midwest and along the East Coast, company CEO Sylvia Wulf said.

Thus far, the only customer to announce it is selling the salmon is Samuels and Son Seafood, a Philadelphia-based seafood distributor.

AquaBounty has raised its faster-growing salmon at an indoor aquaculture farm in Albany, Indiana. The fish are genetically modified to grow twice as fast as wild salmon, reaching market size — 8 to 12 pounds (3.6 to 5.4 kilograms) — in 18 months rather than 36.

The Massachusetts-based company originally planned to harvest the fish in late 2020. Wulf attributed delays to reduced demand and market price for Atlantic salmon spurred by the pandemic.

“The impact of COVID caused us to rethink our initial timeline … no one was looking for more salmon then,” she said. “We’re very excited about it now. We’ve timed the harvest with the recovery of the economy, and we know that demand is going to continue to increase.”

Federal judge rules FDA must reevaluate effects of potential GE salmon escape

November 9, 2020 — AquaBounty Technologies is facing another legal battle over its AquAdvantage salmon, as a California court ruled last week that the Food and Drug Administration (FDA) violated core environmental laws in approving genetically engineered salmon for sale and consumption.

On 5 November, a federal judge in San Francisco ruled the FDA ignored serious possible environmental consequences by approving genetically engineered salmon, and was also violating the National Environmental Policy Act. The judge also ruled the FDA approval was in violation of the Endangered Species Act, as the agency did not consult with the National Marine Fisheries Service and the Fish and Wildlife Service before taking an action that “may affect” a listed or endangered species.

AquaBounty announces Kentucky as next planned GE salmon farm site

October 30, 2020 — AquaBounty Technologies announced that Mayfield, Kentucky, U.S.A., has been selected as its favored site for a future 10,000 metric ton (MT) land-based salmon farm.

The new farm would be the first large-scale commercial facility for the company’s AquAdvantage salmon – a proprietary genetically engineered Atlantic salmon. The new location would be eight times the size of the company’s existing farm in Albany, Indiana, which currently has a production capacity of 1,200 MT.

The Beyond Meat of Fish Is Coming

June 13, 2019 — Salmon has become the guinea pig of the seas when it comes to using technology to supplement falling fish populations. Now it’s moved onto land—and into the laboratory.

The fatty orange fish was the second-most-consumed seafood in the U.S. in 2017, after shrimp, and per capita consumption increased 11 percent, to 2.41 pounds per person, from the prior year, according to the National Fisheries Institute, an industry group. Globally, demand for salmon has skyrocketed, along with that for all fish, fueling overfishing and threatening supply.

Industrial-scale salmon farming, once seen as a solution, has its own problems. Massive stocks of smaller fish are depleted to feed farmed salmon, and parasites flourish in salmon pens where farmers use pesticides, contributing to pollution and ecosystem destruction. Sea lice have infested farms in Norway and Scotland in recent years, and a deadly algae bloom killed salmon in Chile, a top farmed-salmon producer. Farmed fish sometimes escape, too, contaminating nearby wild salmon.

What Will It Take for Americans to Eat Genetically Engineered Salmon?

February 27, 2018 — One day in 1992, a technology entrepreneur sat down for a meeting with a pair of biologists who were studying the genes of fish. The scientists, Hew Choy Leong and Garth Fletcher, were working on a method of purifying “antifreeze proteins” that would help Atlantic salmon (Salmo salar) survive so-called super-chill events in the North Atlantic. Normally these salmon migrate out of the subzero, ice-laden seawater of the far North Atlantic to overwinter in less-frigid waters. Increasingly, though, such fish were being farmed, penned year-round in offshore cages, in near-Arctic waters to which they were not adapted. Fish farmers were looking for a way to keep the fish alive through the winter, and the antifreeze protein seemed like a possible solution.

As the meeting drew to a close, Fletcher and Hew showed Elliot Entis, the entrepreneur, a photo of two fish of equal age. One dwarfed the other. “I sat back down,” Entis recalled recently.

Fletcher and Hew, it turned out, had not just been putting antifreeze proteins into Atlantic salmon. They had also figured out a way to add a growth hormone from Chinook salmon (Oncorhynchus tshawytscha), plus a fragment of DNA from the ocean pout (Zoarces americanus), an eellike creature that inhabits the chilly depths off the coast of New England and eastern Canada. This genetic code acts like an “on” switch to activate the growth hormone. The result was a genetically engineered super-fish that grew nearly twice as fast, on less food, than conventional salmon.

Those salmon, grown and marketed by a company called AquaBounty Technologies that was founded by Entis, could be coming to U.S. grocery stores next year. And they could offer a way out of the deadly spiral of overfishing that is decimating wild-fish stocks.
