Краткое описание определительные ключи | морфология | морфометрия

колючие лучи спинного плавника (общее число) : 0; членистые (мягкие) лучи спинного плавника (общее число) : 25 - 29; колючие лучи анального плавника: 0; членистые (мягкие) лучи анального плавника: 16 - 19; позвонки: 73 - 85. Scales small, more than 100 in lateral line. Gular plate narrow (Ref. 26938). Silvery overall, with bluish on upper surface (Ref. 7251). Branchiostegal rays: 26-33 (Ref. 4639).

биология     глоссарий (например epibenthic)

Occur in shallow neritic areas, over muddy bottoms (Ref. 5217). Also found in brackish estuaries and juveniles are common in lagoons and hyper-saline bays (Ref. 5217). Form large schools close to the shore (Ref. 9987). Feed mainly on crustaceans and small fishes. Spawn in the open sea (Ref. 5217). Larval development is represented by profound changes in body form accompanied by 2 periods of length increase, interspaced by a period of length decrease (Ref. 4639). Noted for their habit of skipping along the surface of the water and for jumping after being hooked (Ref. 5521). Marketed fresh, salted and frozen but considered a second rate food fish (Ref. 3718). Rhynchobothrium bulbifer found in the viscera of the adult (Ref. 37032).

Life cycle and mating behavior Maturities | размножение | Spawnings | Egg(s) | Fecundities | личинки

Spawns offshore, the larvae drifting towards the coast where they shelter and grow (Ref. 9987). Leptocephalus larvae are found in salinities as low as 0.0+ to 0.8 ppt (Ref. 75142).
