dc.description.abstractClarias batrachus do not spawn spontaneously in confined conditions even after induction using synthetic hormones. Current hatchery techniques for seed production of the species involves fertilization of stripped eggs using ground testes suspension from a sacrificed male. The study report the elicitation of spontaneous spawning in C. batrachus and the successful hatching of the eggs collected there from. The mature males and females were induced using ovatideTM and released into a gently sloping drain planted with paddy saplings. The fertilized eggs were collected 24 h post injection and transferred to a flow-through device for incubation. It is observed that bilateral injection of ovatide in combination with complete exclusion of light and total simulation of the natural breeding grounds of the species have positive influence on spontaneous spawning in confinement. With finer refinements, it would be possible to have more control and success in terms of spontaneous spawning and easy collection of the eggs, which is desirable for a commercial hatchery.en_US
