Diagnosis

Body elongate, somewhat compressed laterally, greatest body depth at front of dorsal fin. Head about 19 - 24 % of total length; eyes large; snout length usually less than eye diameter; mouth moderate, terminal, lower jaw always protruding, maxillary at a distinct angle, extending posteriorly to below anterior half of the eye; a small cluster of teeth present on the tongue. Overall coloration silvery, usually brown to dark green on the back, becoming silvery on sides and below. The small non-anadromous form that remains in fresh water is without spotting on the back and only the pelvic fins have black pigment on the tips., the remaining fins are unpigmented. The larger, anadromous form has dark spots on the head, back, dorsal, and adipose fins, and sometimes, on the pectoral fins; all fins have usually dark pigment on the tips.
