Study on the fecundity of brown trout (Salmo trutta fario L.) in River Asiganga, Uttarkashi (Uttarakhand), India


Author(s): MS Rawat, Babita Bantwan and Dhyal Singh

Abstract: A total of 253 brown trout (Salmo trutta fario L.) (130 males and 123 females) were examined for the study of fecundity, spawning season and sex ratio. The length ranged in between 26.15 to 44.15 cm, while, weight from 235 to 1140 gms. The fecundity of brown trout (S. trutta fario L.) was in between 454 to 1052 eggs per female. It was positively co-related with the total fish length (r=0.859), fish weight (r=0.653), ovary length (r=0.828) and ovary weight (r=0.996). Gonadosomatic index (GSI) confirmed that spawning lasted from October to January. The sex ratio of male and female was 1: 0.95.
