"The Atlantic salmon (Salmo salar) is a species of ray-finned fish in the family Salmonidae.....It is found in the northern Atlantic Ocean, in rivers that flow into the north Atlantic and, due to human introduction, in the north Pacific Ocean.[2][3] Atlantic salmon have long been the target of recreational and commercial fishing, and this, as well as habitat destruction, has reduced their numbers significantly; the species is the subject of conservation efforts in several countries.""Wild Caught vs. Farm Raised Salmon.
Over the years, the wild caught stock of Atlantic salmon has been so reduced by over fishing that there is essentially no wild Atlantic salmon left. ... Farmed salmon are raised in net cages located in the ocean close off shore.""Most farm-raised salmon is Atlantic salmon — the only species of salmon living in the Atlantic ocean — and, because in the wild it is an endangered species, fishing for it is prohibited almost everywhere (certainly in the U.S.) and almost all Atlantic salmon sold in stores is farm-raised.Apr 10, 2009""Non-native fish stocking.
Atlantic salmon, brown trout, Chinook salmon, coho salmon and rainbow trout are all currently stocked in one or more of the Great Lakes. Non-native salmonines species were first introduced to the Great Lakes more than 150 years ago, but only the rainbow trout prospered."
