The Atlantic Salmon

Atlantic Salmon, Salmo salar. Once a highly valued commercial fish,  the Maine Atlantic Salmon was declared an endangered species in 2009. Salmon are raised in aquaculture, but many problems, ranging from disease to ecological issues like impact on feed fish and fish pen effluent, are creating difficulties for farm raised salmon.
