Salmon TroutSalmon Trout(Salmo trutta), a fish of the family Salmonidae. The body is covered with small black spots. It is found along the seacoasts of Europe. The typical salmon trout is diadromous, living in the sea for four years and reaching a length of up to 1 m and a weight of up to 13 kg. It feeds on small fish and large crustaceans. It enters rivers for spawning, which occurs between October and December. The fry live in the rivers for two to seven years and then migrate to the sea. Distinctive subspecies of the salmon trout inhabit the southern seas of the USSR. These subspecies include the Black Sea salmon (Salmo trutta labrax, weighing up to 24 kg), the Caspian salmon (S. t. caspius, sometimes weighing over 50 kg), and the Aral salmon (S. t. aralensis, same dimensions as the salmon trout). There are also freshwater forms of the salmon trout, for example, the lake trout (S. t. lacustris) and the brook, or river, trout (S. t. fario). Salmon trout are of great commercial value, and their number has been greatly depleted by man. Both diadromous and freshwater forms are bred. salmon trout
