Wild or Farmed?

The wild Atlantic salmon is a unique and vulnerable fish. It lives most of its life in the ocean but can spawn only in freshwater. Every one of these fish has a special homing device that scientists have yet to account for, and after roaming around in the Atlantic Ocean for two or three years, covering tens of thousands of miles, the fish returns to the same riverbank, only a few feet from where it was hatched, to spawn.

For every five thousand salmon eggs that are laid on sandy riverbanks, only five fish live to reach the ocean. Of these five, only one survives long enough to return home and spawn again. This is a cycle that is vulnerable to overfishing and the effects of human enterprise.
