Background
As one of important economic varieties of Boletus margarita in China, Haliotis discus hannai (Haliotis disco hannai) has been very optimistic in the cultivation situation of China. The haliotis discus hannai is mainly produced in Liaoning province in China, and with the popularization and development of artificial abalone culture technology, the culture area of the haliotis discus hannai is gradually shifted to the south from the north. At the present stage, the main cultivation mode of the abalones in China is artificial cultivation in open sea areas, most cultivation areas are concentrated on Fujian coastal areas and the like, and the yield of the cultivated abalones accounts for about 85% of the total yield of the whole country.
The haliotis discus hannai is bred at the proper seawater temperature of 15-25 ℃, generally in the middle 7-8 months and at the water temperature of 20-24 ℃. When the water temperature reaches 28 ℃, the abalone begins to have the conditions of reduced adhesion rate and death. In the actual culture process, the death rate of the abalones can reach 30-60% after 5-7 days after high water temperature. The sea water temperature in the southern sea area in summer is high, so that the Haliotis discus hannai can be killed massively in summer in the southern summer, and the key factor for restricting the development of the abalone culture industry in China is also achieved.
In view of the above, the present invention is particularly proposed.
