Title of presentation: Fish Reproductive Biology: A Tool for Conservation
The article discusses on understanding reproductive biology of fishes and its implementation for conservation and enhancement of fish production especially endangered as well as commercially important fish species. The practicability of conventional technique in delineating the spawning periodicity of fish has already been proven. Hence, the present study is a detailed enumeration of those techniques and their viability in a hardly familiar and rarely available hill stream catfish Amblyceps apangi from Arunachal Pradesh, India. The study was conducted mainly by observing seasonal variation in gonads of the fish, particularly gonadosomatic index (GSI) to score standard cut off for reproductive maturity. The reproductive staging done on the basis of morpho-anatomy was further validated by histological endeavor. These were confirmed further with necessary justification using ELISA technique for gonadal steroids cycle. Also, exogenous gonadal hormone was tried in vitro on intact ovarian follicles to validate the meiotic maturation following standard method.
