Top of head with numerous, 8-14, fronto-parietal striae; upper jaw with a distinct median notch; 2 supramaxillae present (Ref. 188, 3107, 3259, 30573). Gillrakers very fine and numerous, 75-175 on lower limb of first gill arch, those on inner arches curled; number increasing with growth (Ref. 3107, 3259). Dorsal fin origin a little before mid-point of body; anal fin short and well behind dorsal fin base; dorsal fin with 3-4 unbranched and 13-15 branched rays, anal fin with 2-4 unbranched and 15-19 branched rays, pectoral fin with 1 unbranched and 12-15 branched rays, pelvic fin with 1 unbranched and 7 branched rays (Ref. 3107, 3259). Scales on longitudinal series 39-44; posterior part of scales with perforations (Ref. 3107, 3259). Sharp keeled scutes present along belly; with 15-17 pre-pelvic scutes and 12-14 post-pelvic scutes (Ref. 28, 3259).
Colouration: Back blue-green, flanks silvery with a black spot behind gill opening and up to 10 similar spots along flanks, or high up near dorsal profile (Ref. 188, 3107, 3259, 12484). |
Found in coastal waters (Ref. 3107, 30573); marine, pelagic, but entering estuaries and able to tolerate quite low salinities (7 ppt) (Ref. 188). Feeds chiefly on phytoplankton, mainly diatoms, also dinoflagellates, but also copepods, molluscan and crustacean larvae, prawns, amphipods and polychaetes (Ref. 188). Spawns, at least in Godavari estuary, around February (Ref. 188). Marketed fresh, dried, dried-salted and boiled. Made into fish balls. |
