Population [top]
Population: It is widely distributed and hence has a very large population. However the species is overfished causing considerable decline in the population in southern West Bengal of 26.7% over four decades from 1960 to 2000 (Mishra et al. 2009). In another study in northeastern Sunderbans, the species is known to have declined by 99% in four years (1997-2001) (Patra et al. 2005).
Current Population Trend: Decreasing
Additional data:
? Continuing decline of mature individuals: Yes
? Population severely fragmented: No
Habitat and Ecology [top]
Habitat and Ecology: Inhabits freshwater and tidal waters, in rivers, tanks, channels reservoirs etc.
This catfish inhabits large rivers, tanks and lakes. It is one of the largest, voracious and predatory of the local catfish which thrives well in rivers and tanks also, especially in jheels with gassy magin. The fish prefers muddy tanks subject to periodical flooding from a nullah or river. A tank where this fish exists, usually contains no other good fish. In order to have other fishes in the tanks and reservoirs, it is very necessary to eliminate this fish. It is rather sluggish and stays at the bottom of water in search of food.
Systems: Freshwater
Use and Trade [top]
Use and Trade: This species is heavily utilized as food fish. Juveniles occasionally are caught and exported as ornamental fish. It is also targeted by recreational fisherman as it is considered a good sport fish (H.H. Ng pers. comm.).
Threats [top]
Major Threat(s): Overexploitation of this species for food is a major threat and has resulted in population declines (Mishra et al. 2009; Patra et al. 2005). The effects of other potential anthropogenic threats such as habitat destruction and competition from alien species need to be further ascertained (H.H. Ng pers. comm.).
Conservation Actions [top]
Conservation Actions: The conspecificity of populations from within and outside of the Indian subcontinent requires critical evaluation. Empirical data on exploitation levels for this species throughout the rest of its range (other than southwestern Bengal) is needed. The effects of other anthropogenic threats such as pollution and habitat destruction on population declines need to be further ascertained.
