Illustrations by Joe Tomelleri
Description: Non-native fish that requires cold (less than 70 degrees), well-oxygenated water. Front edge of lower fins lined in white and the tail fin is slightly forked. The midsection of sides has a few large black and red spots while the back has mottled or "wormy" lines. It is also characterized by traits typical to trout - small scales; a small, fleshy 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. It is our smallest trout and is considered a fall spawner - utilizing clean, gravelly riffles in streams. Diet primarily consists of aquatic and terrestrial insects and small fish.
