F
ish diversity, distribution and abundance with environmental parameters from the upstream and downstream parts of two
major north flowing major rivers Son and Tons of Uttar Pradesh were investigated. Overall 61 fish species representing 17
families were collected and Cyprinidae was recorded as the most dominated family represented by 23 species. The threatened
status category of 61 fish species according to the IUCN Red List Criteria 2012 revealed seven species under near threatened,
three species under not evaluated, one under vulnerable (VU) and one under data deficient category. The remaining species
were categorized under least concern. The considerable difference between the relative abundance of fishes of both the rivers
were observed (p<0.05). The abundance and distribution of
Mastacembelus
was recorded highest in the river Tons followed
by
Labeo rohita, Rasbora daniconius
and
Labeo bata
. These species were noticed comparatively lower in the river Son and
abundance of species like
Rita rita, Sperata seenghala, Rasbora daniconius
and
Puntius sophore
were found higher. Further, the
considerable variations between the fish diversity of these rivers were also noticed (p<0.05). Both fish diversity and species
richness showed inverse relationship with respect to altitude. The present study shows that these rivers support considerable
fish diversity with 3.8% vulnerability, which is important for the conservation besides supporting considerable carnivorous
(50-62.5%), omnivores (16.6-29.2%) and herbivores (8.1-16.6%, 3.8-8.3%) species.
