[Starting with the genome of the Atlantic salmon, a heavily farmed species that’s nearly extinct in the wild, scientists made two changes. They took the gene for a growth hormone from the Chinook (or king) salmon, the largest of the Pacific salmon species, and kicked that hormone into overdrive with a promoter gene taken from ocean pout, an eel-like fish that can survive and grow in near-freezing waters. “Usually the salmon’s growth hormone gets turned off during colder months,” says Eric Hallerman, fish conservation scientist at Virginia Tech University. The pout’s promoter gene basically makes sure the Chinook growth gene never gets shut off. Voila: a mega-fish.]

[Currently, the only place the FDA allows the company to grow fish are in aboveground freshwater tanks high in the Panamanian mountains. ...AquAdvantage salmon’s genetic engineers made the fish sterile (also, all the fish are female).]
