Description

The brook trout is a char of the family Salmonidae that can reach about 86 cm but in streams usually stays much smaller. The body is beautifully marked: the brown-green back and dorsal fin carry a pale marbled pattern, the flanks are dotted with light and red spots ringed in blue, and the pelvic fins have white leading edges with a black stripe. The species is native to cold, clear streams, rivers and mountain lakes of eastern North America and needs high oxygen. As a hunter it eats insects, crustaceans, molluscs and small fish. It has been stocked worldwide for sport fishing, including in Europe, where it locally displaces native species. It is a classic, valued sport and food fish.
