My mind is alive to the health, safety, and environmental risks of technological innovation, but at heart I’m a propeller-head. So if someone figures out a way to implant some genes from other fish species to make farm-raised (and therefore not interbreeding with wild fish) Atlantic salmon to make them grow bigger and faster, my instinct is to say “Hurrah.”
Yes, it would be better to change the rules about fishing to be able to raise fish efficiently in the ocean, but that ain’t gonna happen. If you’re anti-GMO, consider this an open invitation to invent some scenario in which allowing GMO salmon in closed-pen fish-farming could have a bad result.
