White spot Disease. Parasitic infestations (protozoa, worms, etc.)

Inhabits rivers (Ref. 4832). A diurnal species and usually solitary. Burrows occasionally. Maximum altitude at 500 m and minimum temperature of 14°C. Feeds on detritus, plants and invertebrates (Ref. 11027). Reproductive migration during the monsoon season towards shallow waters of flood plains. Non-spawning adults usually found feeding in littoral zones.

Potamodromous. Migrating within streams, migratory in rivers, e.g. Saliminus, Moxostoma, Labeo. Migrations should be cyclical and predictable and cover more than 100 km.

Spawns in middle reaches of rivers, where flood water spreads in more or less limpid shallows over fertile flats, well above tidal reaches; also in reservoirs and bundh-type tanks.

Dorsal fin with 12-14 1/2 branched rays; lower profile of head conspicuously arched; short dorsal fin with anterior branched rays shorter than head; 12-16 predorsal scales ; snout without lateral lobe (Ref. 43281).

Adults inhabit rivers (Ref. 4832). A diurnal species and usually solitary. They burrow occasionally. Feed on plants. Spawning season generally coincides with the southwest monsoon. Spawning occurs in flooded rivers. Fecundity varies from 226,000 to 2,794,000 depending upon the length and weight of the fish and weight of the ovary. Widely introduced outside its native range for stocking reservoirs and aquaculture. Utilized fresh (Ref. 9987).
