Breeding method of babylonia areolata cross-breeding seeds

The invention provides a breeding method of babylonia areolata cross-breeding seeds. Male Thailand babylonia areolata and female Hainan babylonia areolata as well as male Hainan babylonia areolata and female Thailand babylonia areolata are respectively adopted for cross breeding, and through processes of parent babylonia areolata sex determination, parent babylonia areolata of different geographical population cross breeding pairing, parent babylonia areolata nutrition enhacnign culture, oocyst collection and hatching, larva culture, young babylonia areolata culture and the like, the cross-breeding seeds with high growth speed and strong disease resistance are cultured. When the method is used for breeding cross-breeding seeds, the culture diseases are reduced, and the occurrence of diseases such as turgescence diseases and shucking diseases can be avoided. The cross-breeding seed stocking is adopted, the yield is increased by 8.2 to 20.3 percent through being compared with that of the traditional breeding seeds, the production value of per square meter of culture pools is increased by 80 to 189.6 Yuan, and the culture economic benefits are improved; antibiotics are not used in the culture process, the product quality is improved, the cultured product conforms to the pollution-free food standard, positive effects are realized on marine ecological environment protection, and the stable healthy and continuous development of the babylonia areolata culture industry is promoted.
