Abstract In the present investigation induced breeding of walking cat fish, Clarias batrachus with synthetic hormone Alpa-FH was made. An optimum result was found in induced spawning by using hormone at the dose of 0.8 ml kg^-1 body weight to female followed by stripping method with higher rate of fertilization (80.4%) and hatching (84.1%). Further, frequency of some common morphological deformities (1.27-3.83%) was also recorded in the induced bred C. batrachus hatchlings in the present study with a highest percentage at the dose of 1.2 ml kg^-1 body weight to female. Results of the present investigation would help mass scale quality seed production of C. batrachus under captive condition to augment market demand of the seed.
