Zusammenfassung: | The invention relates to a method for enhancing resilience of whitebait germplasm. The method is characterized by comprising the following steps of: 1, building a Taihu lake whitebait natural germplasm resource base; 2, building a seedling breeding base: constructing seedling combination units; 3, constructing seedling combination, forming a combination by at least five combination units, expanding and breeding; 4, building a manual spawning ground, and effectively recovering the breeding potential of whitebaits in lakes and reservoirs. The fertilized eggs of whitebaits growing at different areas, different heights and different latitudes are combined based on the gene difference caused by heterogeneity and population genetic changes of ecological environment, and then fed into a relatively sealed lake and/or reservoir to breed young generation, keep and breed, so as to increase the amount of the high-quality population and enhance the resilience of whitebait germplasm, and thus the yield and the quality of t |
