From the New York Times:

The equivalent of 7 to 11 pounds of fresh fish are required to produce 2 pounds of farmed salmon, according to estimates. Salmon feces and food pellets are stripping the water of oxygen, killing other marine life and spreading disease . . . Escaped salmon are eating other fish species and have begun invading rivers and lakes as far away as neighboring Argentina. . . .

The only way to stop fish farms is to demand wild fish from your local megamart or fishmonger; to ask your waiter if the fish is farmed or wild and explain that you will never order farmed fish.

The real litmus test, however, should be flavour. If you’re not convinced, cook some wild and farmed salmon and let your taste buds be the arbiter.

Consumers have a voice; look how far grass-fed, grass-finished beef has come.
