Notopterus notopterus is most likely a species complex (R. Britz, pers. comm.), despite the very wide range as currently accepted.  Until the taxonomic issue is resolved, the species is assessed as Least Concern.  Further work is required to understand the species taxonomy when a reevaluation is also necessary to assess the status of the species.

Current Population Trend:Unknown
Additional data:
Continuing decline of mature individuals:Unknown
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:The species inhabits fresh and brackish waters, and appears to thrive well in lentic waters.

Owing to its carnivorous nature, this fish can only be cultivated in wild waters or in fattening ponds in which large fish are present. It breeds in stagnant or running water in the rainy season. A ripe female bears relatively fewer eggs; they are laid in small clumps on submerged vegetation. Fingerlings are available in upper reaches of Cauvery in July-August. This fish is relished both in fresh and dried state.
Continuing decline in area, extent and/or quality of habitat:No

Use and Trade [top]

Use and Trade: Widely captured for food, and is captive bred.

Threats [top]

Major Threat(s):

The threats to this species are not known.

Conservation Actions [top]

Conservation Actions:

More research into population trends in the wild is required to understand the status of this widespread species.
