    Induced breeding is a technique by which the economically valued ripe fish brooders are stimulated by pituitary extract or other synthetic hormones to breed in captive conditions. Most fishes won't breed in captivity due to insufficient release of pituitary hormones aroused by the disturbance in environmental conditions in controlled systems. The technique was first evolved in Argentina by Houssay, (1930). In 1934, Brazilian researchers could succeed in inducing ovulation by pituitary gland injection. Since then, the technique has been extensively used by various workers. In India, the first attempt on induced breeding was conducted by Khan (1938) on Cirrhinas mrigala. Later Choudhuri, (1955) tried it on minor carps (Esomus danricus, Pseudotropius atherinoide). Ramaswamy and Sundararaj (1956) had done the experiments on catfishes (Clarias batrachus and Heteropneustes fossilis). Induced breeding was successfully carried out in Indian carps such as Labeo rohita, Cirrhinus mrigala, Cirrhinus reba, Labeo bata by Chaudhuri and Alikunhii, (1957) by hormone injection. Since then, the application of this technique has spread widely and now, with modifications, forms a regular part of fish culture programs all over the country
