Eutropiichthys vacha was described from the larger
freshwater rivers of the Gangetic provinces (Hamilton
1822) in India, Nepal, Bhutan and Bangladesh (Ferraris
and Vari 2007). This species is known from the northern
part of the Indian subcontinent southwards to the
Mahanadi River. This species inhabits fluviatile habitats,
particularly in larger rivers with a sandy or muddy
bottom (H.H. Ng 2009). Because this
species is heavily utilized as a food fish, overfishing
is a potential major threat. Indeed, published data
for parts of its natural distribution suggest that
overfishing is a major cause of local population declines
(Mishra et al. 2009). Other 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. The current threats to aquatic
biodiversity in all of its known distribution have
also not been adequately identified. Although IUCN
Bangladesh (2000) identify habitat loss as a major
threat to this species, this does not appear to be
supported by any empirical data. (IUCN). Remarks:Eutropiichthys vacha is still listed
in Fishbase as being in the Schilbeidae family but
it is updated in The Catalog of Fishes as the current
status of being in the Ailiidae family.
