Abstract
Alternative method of genetic resource preservation for fish - surrogate broodstock technologies. Surrogate broodstock technologies refer to techniques where immature germ cells from a target fish species are transplanted into a related species that is easy to raise and mature, so that the related species can produce sperm and eggs of the target species. To introduce surrogate production as a new technique for fish-seed production in aquaculture. It is achieved by inducing germ-line chimerism between different species during early development. PGCs are a key material of this technique to induce germ-line chimera. PGCs from donor species are isolated and transplanted into host species to induce the germ-line chimera. Surrogate production, however, has the possibility to allow efficient fish-seed production and effective breeding and transfer of biodiversity to an aquaculture strain. Conservation and efficient utilization of genetic resources will be achieved through surrogate production combined with the cryopreservation of PGCs.
