Surrogate broodstock technology can increase the production efficiency of commercially important fishes that are difficult to breed in confinement and aid the propagation and recovery of endangered populations. In this study, we report the application of germ cell (GC) transplantation (GCT) for increasing the numbers of progeny produced by small-bodied ornamental fishes by using sexually mature adult fish as recipients. The GCs isolated from prepubertal male goldfish (Carassius auratus) donors (n = 5) were transplanted through the genital papilla into the gonads of adult common carp (Cyprinus carpio) recipients. The endogenous GCs of the recipient were depleted using busulfan (40 mg/kg body weight [BW]; in five doses at 2-week intervals) and high-temperature (38 °C) treatments. Within 4 months after GCT, the donor GCs recolonised the recipients’ gonads and resumed gametogenesis. The presence of donor-derived gametes was confirmed through polymerase chain reaction–restriction fragment length polymorphism analysis in all the surrogate common carp males and females. Artificial fertilisation and induced spawning between surrogate males and females yielded pure goldfish progeny; the fertilisation and hatching rates were similar to those of the controls. These results suggest that GCT could also be potentially applied in commercial aquaculture, mainly to increase the numbers of progeny obtained from small-bodied fishes those having low gamete counts.
