Setipinna phasa (Hamilton 1822)

Belly with 21 or 22 keeled scutes from isthmus to anus. Lower gill rakers with the serrae even or becoming clumped in some specimens. Pectoral filament long, reaching to base of 15th to 39th anal fin ray. Anal fin with upper caudal lobe truncated, shorter than lower. Pectoral fins hyaline, but dark in fishes over 13.6 cm SL.

Acanthogyrus Infestation 3. Parasitic infestations (protozoa, worms, etc.)

Has an extended breeding season, possibly throughout the year.

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): 0; Analspines: 0; Analsoft rays: 66 - 78

Presumably tolerating some salinity.

A riverine species, but also found in estuaries and presumably tolerating some salinity. Adults feed mainly on mysids and small prawns (reduced feeding during breeding), juveniles mainly on copepods. Possibly breeds throughout the year, with peaks in October and November (Hooghly at Barrackpore) or March-May (Ganges at Allahabad). Its large size makes it an attractive foodfish.
