Journal Title: International Journal of Advanced Research (IJAR) - Year 2018, Vol 6, Issue 6
Abstract
An attempt was made to assess the Gonadosomatic Index (GSI) and Fecundity of an indigenous carp, Bangana dero widely distributed all along the foot hill regions of Himalayan ranges of India, Pakistan, Bangladesh, Nepal, Myanmar and China. This species has good food value with fair market demand. GSI of female fish was ranging from 1.192 to 15.785 with a highest value in the month of July (15.546?1.104) and lowest level observed in January (1.132?0.136). Single peak of GSI in the month of July indicates the spawning season of Bangana dero. The absolute fecundity was ranging from 72265 to 184322 ova with an Average fecundity was recorded as 1,11,200-1,44,416.Present findings highlight the reproductive potential of Bangana dero, which will be very helpful for the development of breeding and seed production of this species.
