The key measure of the technique is to set a crab prevention pen to close the ponds. Besides shrimp growing ponds,it also needs water treating ponds. Water entering the ponds must be filtered through a 60 mesh screen. Shrimp fry to be stocked must be WSSV free . The ponds must be disinfected thoroughly to iliminate all the pathogenes and their vectors before fry stocking. In the whole culture period, water added to the ponds must also be disinfected. The prevention efficiency of the technique was 95%~100% in experiments, and 79%~100% in preliminary application in culture practice.展开更多
