抄録

Transgenic technique has been applied to commercially valuable species in recent years and is expected to be a powerful approach for fish breeding. This brief review describes the status quo and discusses the future prospects of transgenic research in salmonidae. The mainstay of this research has been the successful microtechnique whereby a foreign gene is transferred into the blastodisc of a fertilized egg, with the aid of a micropipette. A portion of the microinjected genes is retained in the host cell, integrated into the host chromosome, and expressed before being inherited by subsequent generations. Based on these principles, recently, a Canadian group produced transgenic salmon showing rapid growth by introducing foreign growth hormone gene. In other studies the introduction of freezing resistance and low dissolved oxygen tolerance have been attempted. Besides this, “cell-mediated gene transfer” has been evolving as a convenient and effective way of producing transgenic fish. The benefits of applying transgenic research in aquaculture are also highlighted.
