LWR and Condition factor are two parameters provide fundamental information regarding the growth parameters for sustainable fishery management in water bodies. The length (L) and weight (W) relationship was calculated for Labeo gonius found in Nanak Sagar reservoir, the largest reservoir of tarai region with the total water surface area of 4600 ha in Himalayan state Uttarakhand. The calculation of b for the length and weight relationship (W=aLb) was recorded as 2.827 for 72 samples. The average allometric coefficient ‘b’ of the length-weight relationship was found (2.827) is a negative allometric growth pattern.  Further results showed correlated LWR (r2 = 0.959) of fish whereas, Fulton’s condition factor (K) was calculated 2.755.
