Diagnostic Description
provided by Fishbase
Body tapering, belly rounded before pelvic fins, with 6 to 9 + 7 to 11 = 13 to 19 keeled scutes from just behind pectoral fin base to anus. Maxilla short, not reaching to edge of gill cover. Pectoral fin with 10 to 13 long filaments; the branched fin rays much shorter those of pelvic fin.

Migration
provided by Fishbase
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).

Trophic Strategy
provided by Fishbase
Occurs in coastal and in tidal stretches of rivers, but apparently no data on salinity tolerances, although its presence above Barrackpore on the Hoogly suggests that it can live in freshwater.

Biology
provided by Fishbase
Occurs in coastal and tidal stretches of rivers, but apparently no data on salinity tolerances. Its presence above Barrackpore on the Hooghly in India suggests that it can live in freshwater. Larvae feed on copepods; thereafter mainly on copepods, but also on prawns, larval decapods and other crustaceans. Breeds in the lower parts of estuaries. The time and duration of the breeding season reported vary for different estuaries in India.

Importance
provided by Fishbase
fisheries: minor commercial; price category: medium; price reliability: very questionable: based on ex-vessel price for species in this family
