Abstract
Salmon enhancement is the process by which wild salmon stocks, often under the possible threat of depletion, are supplemented by controlled hatchery production which is released into rivers, estuaries, or open sea waters, with the goal of supporting or building up these stocks. In most cases, the stocks used are of the same genetic source as the original stock in the system, they mingle with the wild stock, and are caught in the same salmon fishery as that for the wild stocks. Salmon ranching by comparison has been described by Thorpe as ‘an aquaculture system in which juvenile fish are released to grow, unprotected, on natural foods in marine waters, from which they are harvested at marketable size’.(1)
