deskripsi pendek Morfologi | Morfometrik

Duri punggung (Keseluruhan (total)): 0; duri punggung lunak (Keseluruhan (total)): 11-13; Duri dubur 0; Sirip dubur lunak: 10 - 14; vertebrata, bertulang belakang: 58 - 63. Distinguished by the gill rakers that are longer than 20% of the interorbital width, 19 to 25 gill rakers (with modal counts of 22 or 23), and a pronounced hump behind the head in adults (Ref. 27547). Adipose fin well developed, often larger in males; axillary process present in pelvic fins (Ref. 27547). Dark brown to midnight blue above fading to silver on sides and wide beneath; no parr marks in young (Ref. 27547).

Biologi     Daftar kata (contoh epibenthic)

Inhabits coastal waters near shore (Ref. 5723), lower reaches of rivers with slow current, large lakes with tributaries, floodplain lakes, deltas and estuaries, brackish waters (Ref. 59043). Migrates up to more than 1,200 km inland for spawning (Ref. 5723). Overwinters near river mouths (Ref. 5723). There are non-migratory freshwater populations. Adults feed mostly on mollusks, crustaceans and chironomid larvae (Ref. 28219).

Life cycle and mating behavior Kematangan | Reproduksi, perkembang biakan | Pemijahan | telur-telur | Fecundity | Larva

Upstream spawning migrations may be extensive but some populations seldom venture far upstream and still others may never go to sea at all (Ref. 593). Mature adults migrate upstream as early as June to spawn in October. It is assumed that the young hatch in late winter and spring, subsequently moving downstream, to return as mature adults 4 to 6 years later (Ref. 27547).
