Labeo rohita; Day, 1878

Labeo rohita; Shaw and Shebbeare, 1937

Labeo rohita; Bhuiyan, 1964

Common name: Rohu

Local name: Rui, Rohit, Rou

Taxonomy position:

Phylum- Chordata


Order- Cypriniformes

Family- Cyprinidae

Genus- Labeo

Fin formula:

D. 15-16 (3/12-13);   P1. 16-17;   P2. 9;   A. 7(2/5). (Rahman, 2005)

Description of the species:

According to Talwar and Jhingran (1991), body moderately elongate, its dorsal profile more arched than the ventral profile, snout fairly depressed, nostrils two pairs and at anterior superior angle of orbits, gill-openings wide. Gills rakers feeble and arranged at short intervals, lateral line complete, scales moderate. According to Rahman, (1889) it attains over 90 cm in total length.

Habit and Habitat:

Its food comprises crustaceans and insect larvae in early stages (Mookerjee et. al., 1946). The percentage composition of food of L. rohita may be algae 35%, higher plants 20%, protozoa 23%, crustaceans 15%, mud and sand 7%. L. rohita takes small percentages of mud which contains organic matter and various salts. This species is available throughout Bangladesh. Ponds, rivers, rivulets are its main habitats (Bhuiyan, 1964). The fecundity of this species varies form 2,26,000 to 2,79,4000 depending upon the length and weight (Talwar and Jhingran,1991)

Economic importance:

Rohu is regarded an excellent game fish and seems to put up a better fight in a river than in a tank. A number of interspecific and intergeneric hybrids have been produced. The most promising intergeneric hybrid, male Catla ´ female Rohu combines the quick growth of Catla and small head of Rohu (Talwar and Jhingran, 1991).

Ecological role:

Rohu is bottom feeder and prefers to feed on plant matter including decaying vegetation.
