Salmon Trout

Salmon Trout, SEA-TROUT (Salmo trutta), a valuable British food-fish, ranging from the south of England to Orkney and Shetland, and found in Wales and Ireland, where it is known as the White-Trout. It is closely allied to, but smaller than, the salmon, which it resembles in habit. The body is thicker than that of a salmon of the same length, and the hinder margin of the gill-cover is not so rounded. On their first return from the sea they present a silvery appearance, whence fish at this stage were sometimes made a distinct species (S. albus).
