Producing fish to spawn by artificial methods is called induced breeding. Labeo rohita are induced to spawn by the injection of pituitary extract, a process called Hypophysation. Hypophysation is a technique of induced breeding in Labeo rohita by injecting pituitary gland extract. In hypophysation, the pituitary gland extract is injected into intramuscular/pectoral fin region of fish. The gland induces the fish to breed. When the pituitary gland of the same species is used, the hypophysation is called homoplastic. Induced breeding is practised in a wide variety of species, with Hypophysation we can get pure seeds in large number in all seasons. With this technique we can produce hybrid varieties of species. This technique shows high fertilization rate(70-80%) and Hatching rate (75-85%) this study explodes about procedure and result of hypophysation technique.
