Dorsale stekels (totaal) : 0; Dorsale zachte stralen (totaal) : 11 - 15; Anale stekels: 0; Anale zachte stralen: 17 - 27; Wervels: 43 - 44. Body moderately deep; belly with 15 to 18 + 8 to 12 scutes. Mouth small. Last dorsal fin ray long, about equal to distance from snout tip to mid-pectoral fin or beyond; anal fin relatively short. Scales relatively large, regularly arranged. A dark spot behind gill opening. Gill rakers fine and numerous (Ref. 188). Body bright silvery, especially on sides, opercles and underparts. Back and upper sides bluish black or dark olivaceous (Ref. 37032).
Often schooling, occurring mainly in freshwater (in large rivers, reservoirs, lakes, and swamps). Prefer the presence of smooth, steep-sided surfaces such as dams, cement-lined pools and rip rapped streams (Ref. 39049). But adults are also found in brackish or saline water of estuaries and bays (up to 32.3 ppt salinity (Ref. 39050); juveniles to about 15 ppt). Larvae are pelagic probably found only in freshwater (Ref. 39046). Filter-feeders, but not entirely herbivorous since recorded food items include copepods, cladocerans and fish fry. Also feed on organic material of sand and detritus bottoms (Ref. 9114). Breed in the spring and in autumn, in freshwater, near or over plants or other objects. Eggs adhere to aquatic vegetation (Ref. 4639). Caught exclusively in fresh waters and sometimes in mouths of rivers (Ref. 9291). Also Ref. 58302.
Breed in spring and again in autumn, in open waters near or over plants or other objects; eggs slightly adhesive (Ref. 188). Females can produce 5,000 to 20,000 eggs depending upon their size (Ref. 44091).
