Present study was conducted on induced breeding of commercially important Clarias batrachus due to the non-availability of its quality seeds from the natural resources for environmental degradation, shrinkage of natural breeding ground and illegal killing of juveniles and brood fishes. The aim of the study was to achieve success in fertilization and hatching using various doses of different inducing agents at different temperatures and latency periods followed by stripping method. In this study the developmental stages of fish (fertilized egg to 45th day old fish) were characterized chronologically. A trial was also made to optimize the survival rate of young developing fish upto 45th day by manipulating their feeding schedule and environmental conditions. The breeding experiments were done with pituitary gland extracts (40 and 120 mg/kg. body weight .. View More»
