Application of Gene Transfer in Freshwater Fish: A Review

In the field of aquaculture, genetic engineering technology has been widely used in fish for production with the aims of increasing the growth rate of fish, regulating gonadal maturity, sex differentiation and sterility. One of the modern techniques that is expected to be a useful tool in the development of aquaculture is gene transfer technology. Transgenic fish have been established, especially for the purpose of enhancing the growth rate in aquaculture. Aquaculture production is expected to be increased several times to meet future food needs in the form of fish due to the increase in human population. This technique has been applied to species that have economic value. This review describes the variation of gene transfer methods, persistence and expression of the transferred genes, their applications and future prospects of gene transfer research in aquaculture.
