The transplant fish production method includes selecting a donor fish species, selecting first and second fish species which are a combination that could be sterile, producing a hybrid fish species of the selected first fish species and second fish species, and transplanting reproductive cells of the donor fish species into the produced hybrid fish species.
Claims21
A method of producing transplant fish comprising:
- producing a hybrid fish species of a first fish species and a second fish species, wherein the first and the second fish species are selected from Auxis genus, Euthynnus genus, Katsuwonus genus, or Thunnus genus, and wherein the hybrid fish species is deficient in producing reproductive cells;
- and
- transplanting undifferentiated reproductive cells of a donor fish species of Thunnus genus into larvae of the hybrid fish species to obtain the transplant fish, wherein the transplant fish is capable of producing donor fish species-derived gametes.
A method of producing a hybrid fish species comprising:
- producing a hybrid fish species of a first fish species and a second fish species, wherein the the first and the second fish species are selected from Auxis genus, Euthynnus genus, Katsuwonus genus, or Thunnus genus, and wherein the hybrid fish species is deficient in producing reproductive cells.
