METHOD FOR PRODUCING FISH GAMETES FOR FARMED FISH PRODUCTION USING SURROGATE PARENT FISH, APPLICABLE TO SURROGATE PARENT FISH OF DIFFERENT SPECIES

摘要

The present invention addresses the problem of providing a method for producing fish gametes in techniques of farmed fish production using a surrogate parent fish, said method being applicable to a surrogate parent fish of a different species and thus broadening the scope of fish species usable as the surrogate parent fish. To solve this problem, provided is a method for producing fish gametes using a surrogate parent fish, said method comprising: hybridizing a first fish, which can serve as a surrogate parent fish for a donor fish, with a second fish, which cannot serve as a surrogate parent fish for the donor fish, to construct a hybrid fish capable of serving as a surrogate parent fish for the donor fish; and, using the hybrid fish thus constructed as a recipient, transplanting separated germ cells of the donor fish thereinto and thus inducing differentiation to a germ cell line.
