Hydroelectric power developments in Sweden are a menace to the populations of Atlantic salmon, Salmo salar L. Conservation measures, started as early as in the 1860ˈs, now aim at the substituting of hatchery‐reared 2‐year‐old smolt for the freshwater part of the life cycle of the salmon. The smolt plantings will soon reach 2 million annually, and the return now amounts to about 12 percent (100‐125 pounds of salmon per 100 smolts), mainly taken as feeding fish in the sea. The artificial maintenance of the salmon populations is within reach.
