Cross Barred Grant

Eggs are guarded and fanned by the male parent (Ref. 205).

Amphidromous. Refers to fishes that regularly migrate between freshwater and the sea (in both directions), but not for the purpose of breeding, as in anadromous and catadromous species. Sub-division of diadromous. Migrations should be cyclical and predictable and cover more than 100 km.Characteristic elements in amphidromy are: reproduction in fresh water, passage to sea by newly hatched larvae, a period of feeding and growing at sea usually a few months long, return to fresh water of well-grown juveniles, a further period of feeding and growing in fresh water, followed by reproduction there (Ref. 82692).

Dorsal spines (total): 11 - 12; Dorsal soft rays (total): 10 - 11; Analspines: 3; Analsoft rays: 8 - 9

The fish is a bottom feeder and omnivorous . Has inferior mouth which enables it to feed on bottom organisms.

Adults inhabit salt and brackish waters of bays and estuaries, penetrating into fresh water (Ref. 1601). Juveniles are sometimes found in streams within 5-10 km of the sea (Ref. 2847). Eggs are guarded and fanned by the male parent (Ref. 205).
