Should the water that hatches Babylonia eggs be disinfected?
Dongfeng snail is commonly known as "Hua snail", "Hai pig snail" and "Nanfeng snail" in Guangdong. Its meat is delicious, crisp and refreshing, and it is a very popular high-quality marine shellfish in domestic and foreign markets. The main species in China are Babylonia quadrata, Babylonia mud and Babylonia Taiwan Province. Babylonia is considered as one of the most promising marine aquaculture varieties in 2 1 century, which has been accepted by farmers in the southeast coast and gradually formed a production scale. From 2000 to 2002, the South China Sea Fisheries Research Institute conducted a scientific research experiment on artificial breeding and reproduction of Babylonia in the coastal areas of Guangdong Province.
Culture techniques include pond culture, cage culture and port purse seine culture. Pond culture adopts soil pond and cement pond. Poison pool and solar pool should be carried out in advance before stocking in soil pool. Inlet water should be filtered through the gate net to prevent harmful organisms such as fish, crabs and snails from entering the culture pond. The number of seedlings per mu of Babylonia is 50,000 ~ 60,000, and the suitable specification is 0.5 ~ 1.5cm. After stocking, the water quality should be kept relatively stable, and the intertidal soil pond should make full use of the twice-monthly spring tide period of the ocean to improve the water quality; The daily exchange water of cement pond culture is about 1/3. Feed mixed fish, shellfish or shrimp every morning and evening. Before feeding the feed, remove the bones and shells and chop them with a meat grinder or by hand. The daily feeding amount is 5 ~ 10% of the total weight of Babylonia, and the actual feeding amount on that day should depend on the remaining feeding amount. The aquaculture water depth is 60 ~ 100 cm. Can be raised alone or mixed with shrimp, fish and other shellfish. After 8 ~ 10 months of culture, Babylonia can meet the market specifications.
