Maximum lengths: 30 cm (Bhuiyan, 1964; Talwar and Jhingran, 1991; Shafi and Quddus, 2001) and 27.9 cm (Rahman, 1989 and 2005).

Habitats: Very common in pond, ditches, swamps and marshes but found in muddy river also. Recorded from the Chalan beel (Galib et al., 2009 and 2010); Padma river in Rajshahi (Samad et al., 2010).

Food and feeding: Mollusks 15.5%, Cypris 15.6% , Chironomid larvae 13.4%; fish and its scales 11.1%, eggs of invertebrates 13.2%, copepod 16.5%, weeds 20.3%, detritus 41.0%, and fungus and others 16.3% (Shafi and Quddus, 2001).

Body composition: Each 100 g contains- protein 23.0 g, fat 0.6 g, calcium 670 mg, phosphorus 650 mg and water 79.3% (Siddique, 1996).

Spawning: Attains sexual maturity at one year of age when male is generally 5.5 cm and female is 12 cm (Talwar and Jhingran, 1991). Induced breeding is recorded in hatcheries of Jessore district, Bangladesh (Galib, 2011).

Fertilized eggs are green (Bhuiyan, 1964), adhesive, demersal and spherical in form (Talwar and Jhingran, 1991). Fecundity was measured 2,843 to 44,724 (Shafi and Quddus, 2001).

Fishery info: Used as food fish in Bangladesh. High economic importance and of great demand because of medicinal value (Talwar and Jhingran, 1991). Recommended for patients after recovery from malaria for its invigorating qualities (Bhuiyan, 1964). Always marketed in live condition.
