Abstract
This study provides length-weight relationship and condition factor (K) of Indian river shad Gudusia chapra (Hamilton,
1822) collected from Panchet Reservoir, Jharkhand, India during October 2014 to September 2015 using gillnets and
drag nets. About 342 specimens (153 male and 189 female) of length range 4.7 to 15.1cm were collected. Length-weight
relationship for male and female were calculated separately. The difference between the sexes was insignificant (independent
t-test, p>0.05). The pooled length-weight regression equation was estimated as log W=-1.863+2.855 log L (r=0.983) which
indicated negative allometric growth. The value of condition factor (Kn value) was observed to be nearer to or greater than
one in both sexes, indicative of the general wellbeing of the fish in the Panchet Reservoir. This is the first report on lengthweight
relationship parameters of G. chapra from an Indian reservoir.
