Breeding method of babylonia areolata cross-breeding seeds

Abstract

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.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a method for breeding hybrid seedlings of snails. Background technique [0002] Fangban Dongfeng snails are referred to as Dongfeng snails for short, commonly known as flower snails, and belong to Gastropoda, Antagliota, Mollidae, and Dongfeng snails. In China, it is mainly distributed in the coastal areas of Fujian, Guangdong, Guangxi and Hainan provinces in the tropics and subtropics. It is a high-quality shellfish with larger individuals and faster growth speed among several kinds of Dongfeng snails distributed in China. Its meat is delicious, nutritious, crisp and refreshing, and it is a new seafood delicacy at home and abroad in recent years. [0003] There are currently two species of snails cultivated in Hainan. One is the Thai snail and the other is the Hainan snail. The Thai snail grows faster than the Hainan snail. However, Both species are prone to "swollen kis...

Problems solved by technology

[0003] There are currently two species of snails cultivated in Hainan. One is the Thai snail and the other is the Hainan snail. The Thai snail grows faster than the Hainan snail. However, Both species are prone to "swollen kiss disease" and "hulling disease" during the breeding process, which requires the use of antibiotics, which reduces the quality of the product, which is not conducive to the protection of the marine ecological environment, and the survival rate of breeding is not ideal
