Why is farmed salmon raised in closed containment systems more sustainable than farmed salmon raised in net pens?
Coho salmon raised in a land based closed containment operation in Washington State was the first salmon farm to receive a “Best Choice” ranking for environmental sustainability by the Monterey Bay Aquarium/SeaChoice. Closed systems separate farmed fish from wild fish and the environment allowing waste, escapes, and spread of disease and sea lice to be controlled. For all of these impacts this closed containment salmon ranked “Best Choice” where net pen farmed salmon ranked “Avoid”.
