代孕亲鱼技术有助于在代孕体中产生供体来源的配子,包括将供体的生殖细胞移植到不同品系或不同物种的受体中。该技术在水产养殖领域的应用前景如下:(1)通过将具有优良性状的单个鱼的供体生殖细胞移植到许多受体鱼中,高效可靠地生产具有优良遗传性状的后代;(2)利用代期短的受种产生代期长的种的配子,减少鱼的繁殖时间;(3)通过冷冻生殖细胞长期储存有价值的物种或品系作为遗传资源供移植使用;(4)将因体细胞突变而不育的供体鱼的生殖细胞移植到没有这种突变的正常受体体内,从而大规模生产遗传不育鱼。预计这些技术的结合将大大加快水产养殖品种的繁殖。在使用代亲鱼时,重要的是使代亲鱼技术适应更广泛的渔业物种,并进一步提高供体配子生产效率。
Surrogate broodstock technology facilitates the production of donor-derived gametes in surrogates, and comprises transplanting germ cells of a donor into recipients of a different strain or different species. The following applications of this technology are expected in the field of aquaculture: (1) the efficient and reliable production of offspring carrying superior genetic traits by transplanting donor germ cells from a single selected fish with superior traits into many recipient fish; (2) the reduction of the time required to breed fish by using a recipient species with a short generation time to produce gametes of a species with a long generation time; (3) the long-term storage of valuable species or strains as genetic resources by cryopreserving germ cells for transplantation; (4) the mass production of genetically sterile fish by transplanting germ cells of a donor fish that is sterile due to a mutation in the somatic cells into normal recipients without this mutation. It is expected that a combination of these techniques will greatly accelerate the breeding of aquaculture species. It is important to adapt surrogate broodstock technology to a wider range of fishery species and further improve the efficiency of donor-derived gamete production when using surrogate broodstock.
