背面の脊椎 (合計): 4 - 5; 背鰭 (合計): 8-9; 肛門の骨 3; 臀鰭: 8 - 10. Greenish-grey dorsally; flanks and abdomen silvery; fins grey or bluish with dusky margins and may appear yellowish at base (Ref. 9812). Pectoral with golden base, and perhaps a dark spot (Ref. 9812). With rudimentary axillary scale.
Occur in shallow coastal waters, and from brackish water to freshwater regions of rivers (Ref. 41299). Form schools (Ref. 40448); in larger aggregations during spawning, which takes place at sea (Ref. 2830). Feed on small algae, diatoms, forams, benthic polychaetes, crustaceans, mollusks, organic matter and detritus; fry feed on copepods and floating algae (Ref. 40448). Oviparous, eggs are pelagic and non-adhesive (Ref. 205). Caught mainly during the spawning season and is sold fresh; the roe is highly appreciated.
