Progress on Research of Fish Androgenesis
鱼类雄核发育的研究进展

Fish andtogenesis is a kind of secial sexual development which is controlled by male nucleus and it is an important part of fish unisexual development. This paper summarizes the progress of fish androgenesis comprehensively in the world.It includes the techniques of inactive female nucleus of eggs and diploidization of male nucleus. The methods of inactive female nucleus are carride out by using γ,X and ultraviolet (UV)rays to irradiate the eggs,the irradiation dosages and methods are different based on the different researchers. The techniques of diploidization of male nucleus are carried out by using hydrostatic pressure, heat and cold shock to restrain the fish mitosis,the diploidization condition are different from species to species.Meanwhile,the paper evaluates the application perspectives of fish androgenesis on the genetics and breeding.
