The technique of breeding fish by other than its natural course is known as induced breeding. Induced breeding techniques have been developed for production of quality fish seed of cultivable varieties. These techniques have allowed farmers to profitably breed and raise species that do not naturally reproduce in captivity, and to manipulate the timing of reproduction to suit production cycles. Induced breeding is necessary to control timing and synchrony of egg production. Various synthetic hormones like ovatide, ovaprim, wova-FH, ovopel, HCG and LHRH are used in induced breeding of fishes. Newly formulated inducing agents are also being tested for the induced breeding performance by various researchers in different parts of the country, under different climatic conditions, with varying degree of success. These synthetic hormones have several advantages which include ready to use in liquid form, consistent potency and stable with long shelf life. The present review focuses on the effect of GnRH, HCG and Kisspeptin hormone on induced breeding of fishes.
