Among the most significant advancements in the field of aquaculture during recent times is the development of techniques to induce reproduction in fish. 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. Some species will not readily breed in captivity due to environmental or culture conditions that are different from those found in nature, such as water temperature or substrate type. These conditions may cause stress or may not provide the signals needed to complete the reproductive process. Numerous hormones have been used to induce reproduction. Two methods have emerged over the past few years that seem to offer the best chance for success at the least expense. They are injection of a GnRH analog with dopamine antagonist and injection of gonadotropin. Chinese carps are quick growing economic food fishes extensively cultured in ponds in China, Japan and some of the South-East Asian countries. Grass carp is herbivorous and consume vegetation and increase natural food production in the pond by nutrient recycling and fecal production
