• Interest in reproductively sterile fish in aquaculture has prompted research into their production. Several meth-ods are available for inducing sterility and optimizing its application in the global fishery industry. Sterilization can poten-tially be accomplished through irradiation, surgery, or chemical and hormonal treatment. Alternative approaches include triploidization, hybridization, and generation of new fines via advanced biotechnological techniques. Triploids of many com-mercially important species have been studied extensively and have been produced on a large scale for many years. Novel approaches, including disruption of gonadotropin releasing hormone signalling and genetic ablation of germ cells, have been developed that are effective in producing infertile fish but have the disadvantage of not being 100% reliable or are imprac-tical for large-scale aquaculture. We review currently used technologies and recent advances in induction of sterility in fish, especially those intended for use in germ cell transplantation. Knowledge of the implications of these approaches remains incomplete, imposing considerable limitations.
