Short description

Dorsal spines (total): 0; Dorsal soft rays (total): 10-14; Anal spines: 0; Anal soft rays: 16 - 23; Vertebrae: 62 - 73. Adipose with long base, about 1.5 times as long as the orbit or longer, outer margin only slightly curved (Ref. 6885). Olive green on dorsal surface, merging into silvery on sides and ventral surface (Ref. 6885).

Oceanic species found in schools (Ref. 2850). Nerito-pelagic (Ref. 58426). Adults feed on planktonic crustaceans, copepods, euphausiids, amphipods, marine worms, and small fishes (Ref. 6885, 35388). Mature individuals move inshore in large schools to spawn (Ref. 2850). In the spring large spawning shoals migrate toward the coasts, males usually arrive first. Often entering brackish and freshwater (Ref. 37812). Semelparous (Ref. 51846). Produces 6,000-12,000 adhesive eggs. Females are valued for their roe, males are utilized as fishmeal. Marketed canned and frozen; eaten fried and dried (Ref. 9988). Possibly to 725 m depth (Ref. 6793).
