The present study was aimed to assess the proximate biochemical composition of body and faecal matter of Tor tor fed with feed combination containing 25% CP (T-1), 30% CP (T-2), 40% CP (T-3) and control group (T-4) containing 20% CP. The results of the proximate composition of the faeces of Tor tor revealed the higher CP% of 18.64±0.03 in fishes fed on feed containing 40±0.01 CP in the basal diet. The whole body carcass analysis revealed higher concentrations of accumulated CP% as high as 65.34±34 (T-3), fed with 40% basal crude protein. The overall study revealed that inclusion of 40% CP in mahaseer diet could lead to better growth and feed efficiency.
