Uses: no uses
Comments: Reported from northern Japan (Ref. 11230). Aparently landlocked populations (races) exist in the lakes in eastern Hokkaido and eastern Honshu. These lakes, however, are probably saline (see p. 115, Ref. 188). Also Ref. 6885, 9988, 27436, 37812, 96339. Status of threat: Threatened populations of Lake stocks of Pacific region in Honshu Island (LP) (Ref. 94887).

Short description

Dorsal spines (total): 0; Dorsal soft rays (total): 13-21; Anal spines: 0; Anal soft rays: 12 - 23; Vertebrae: 46 - 58. Without prominent keel; no median notch in upper jaw. Gill cover without radiating bony striae. No distinctive dark spots on body or fins. Overlaps C. harengus in White Sea, but distinguished by fewer vertebrae (usually 52 to 55; cf. usually 55 to 57) and fewer post-pelvic scutes (10 to 14; cf. 12 to 16). Dark blue to olivaceous above, shading to silver below (Ref. 27547). Precaudal vertebrae: 29-31-32; caudal vertebrae: 19-22-22 (Ref. 265).

Neritic species (Ref. 11230). A coastal and schooling species (Ref. 188). Landlocked populations exist. Mature adults migrate inshore, entering estuaries to breed. During the summer of their first year, young form schools in shallow bays, inlets and channels that appear at the surface; these schools disappear in the fall and remain in deep water for the next 2-3 years (Ref. 6885, 27547). Young feed mainly on crustaceans, but also take decapod and mollusk larvae; adults prey mainly on large crustaceans and small fishes (Ref. 6885, 27547). Because it does not undertake extensive coastal migrations, the mixing of local populations is relatively rare (Ref. 27547). In the eastern Pacific, the fish is mainly caught for roe markets in Asia (Ref. 9988). There is a fishery for eggs laid on kelp, which when salted, is called kazunoko-kombu, and is considered an delicacy in Japan (Ref. 27547). Used in Chinese medicine (Ref. 12166). Utilized fresh, dried or salted, smoked, canned, and frozen; eaten pan-fried, broiled, and baked (Ref. 9988). Possibly to 475 m depth (Ref. 6793).
