Abstract
The present study was carried out on freshwater crab in hillstream Khoh of district Pauri Garhwal in Uttarakhand state. Samples of crab were collected from the population inhabits the hillstream Khoh on monthly basis during May 2011 to April 2012. The regression equations for the length-weight relationship in crabs were obtained as Y=2.045X+0.266 and Y=1.522X+0.392 for males and females respectively. The ANOVA test revealed significant differences in carapace length-weight relationship at p<0.05 for both the sexes. Allometric growth pattern was observed in the study for both sexes of P. koolooense. A weak relationship was observed between length and weight of the specimen.
