Kingdom Phylum Class Order Family
Animalia Chordata Actinopterygii Siluriformes Bagridae

Scientific Name: Mystus bleekeri (Day, 1877)
Taxonomic Notes: Mystus bleekeri was described from the Ganges River drainage and Myanmar (Day 1877), but the lectotype designation of Sharma and Dutt (1983) restricts the type locality to the Ganges River drainage.

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2010
Date Assessed: 2009-10-05

Although there is no information on the population and its trends for this species, current evidence indicates that it is still relatively widespread and abundant. Despite being targeted in fisheries in some regions of its distribution, the level of exploitation is not deemed high enough to be a threat to long-term survival of this species. Mystus bleekeri is therefore assessed as Least Concern.

Population [top]

Population:There is no information on the population size or trends for this species, although this is a fairly common species in the Ganges-Brahmaputra system.
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species inhabits a large variety of freshwater bodies, primarily rivers and lakes.
Continuing decline in area, extent and/or quality of habitat:Unknown

Use and Trade [top]

Use and Trade: This species is targeted as a food fish in West Bengal, Assam and Tripura in India and in Bangladesh (W. Vishwanath, S.C. Dey pers. comm.).  In other parts of its range, no major fishery exists for this catfish; but is obtained in the fishing operations along with other fishes. It is also sporadically caught and exported as an ornamental fish (H.H. Ng pers. comm.).

Threats [top]

Major Threat(s): The current rate of fishing for this species is not a threat in eastern and northeastern India. In other regions, the threats to this species are unknown, since there is no information on the biology of this species and therefore the impact of potential threats (especially those of an anthropogenic nature) remains unknown. Despite the paucity of knowledge regarding potential threats, this species is still relatively abundant and widespread. This may be an indication that there are no major widespread threats to this species at the moment.

Conservation Actions [top]

Conservation Actions: There is insufficient information on the distribution, biology and potential threats for this species. Catch data for this species is also needed.
