The use of hormones for aquatic animals has a long history with different goals in the world. In our country, the use of hormones in aquatic animals has been done for about two decades, and in ornamental fish have begun since about a decade ago. Several species of ornamental fish have undergone hormone therapy, including cichlids, Gupi, Koi, Gurami, Molly, Swordfish and others. Considering the global competition in ornamental fish production as well as the increase in the price of the currency that imports ornamental fish imports, it seems necessary to perform various biotechnological methods in domestic products in order to increase the quantity and marketability of various ornamental species. . Hormone therapy is one of the fastest, least costly and, of course, most effective biotechnology methods in aquatic animals, especially ornamental fish, which can greatly contribute to the supply and quality of domestic markets. Sex reversal and sex control are some of the most important goals of hormonal induction. The most important natural hormones used are 17-alpha-methyl testosterone and 17-beta-estradiol are the different therapeutic time and therapeutic dosages for induction of hormone in different fish species.
