Inside an Indiana aquafarming complex, thousands of salmon eggs genetically modified to grow faster than normal are hatching into tiny fish. After growing to roughly 10 pounds (4.5 kilograms) in indoor tanks, they could be served in restaurants by late next year.
The salmon produced by AquaBounty are the first genetically modified animals approved for human consumption in the U.S. They represent one way companies are pushing to transform the plants and animals we eat, even as consumer advocacy groups call for greater caution.
AquaBounty hasn't sold any fish in the U.S. yet, but it says its salmon may first turn up in places like restaurants or university cafeterias, which would decide whether to tell diners that the fish are genetically modified.
"It's their customer, not ours," said Sylvia Wulf, AquaBounty's CEO.
To produce its fish, Aquabounty injected Atlantic salmon with DNA from other fish species that make them grow to full size in about 18 months, which could be about twice as fast as regular salmon.
