Brown Trout
Salmo trutta
Illustrations by Joe Tomelleri
Description: Non-native fish that requires cold (less than 70 degrees), well-oxygenated water. It has prominent spots on back and sides, often red or orange and accented with halos. The tail fin is not forked and generally free of spots. It also has typical trout characteristics - small scales, adipose fin on the midline of the back near the tail, and a small, triangular projection (the axillary process) at the upper end of the pelvic fin. Our largest trout and spawns in fall or early winter in streams containing clean, gravelly riffles. They are typically less vulnerable to fishing pressure than rainbows. They are somewhat of an opportunist - diet includes aquatic and terrestrial insects, snails, amphipods, crayfish, and typically more small fish than do rainbows.
