Abstract

An attempt was made to assess the gonadosomatic index (GSI) of an indigenous coldwater fish Schizothorax richardsonii commonly known as ?Asela? in Uttarakhand is one of the most important sports fishery in the state. The fish inhibits in streams and rivers of Himalayan and Sub- Himalayan regions. The gonadosomatic index of both captive reared and wild stocks of both Female and Male Schizothorax richardsonii was calculated which ranges from 5.72% to12.91% and 1.80% to 7.24% in captive reared Female and Male fish respectively. While in wild brooders ranges from 5.33% to 14.10% and 1.52% to 6.74% in Female and Male respectively. Gonadosomatic index will be helpful thus, gives an idea about maturity level in fishes as well as estimation of breeding season.
