Enterocytozoon hepatopenaei (EHP) is one of the major diseases in breeding of Litopenaeus vannamei. The harm and causes of EHP infection of Litopenaeus vannamei were analyzed, and corresponding comprehensive preventive measures were put forward to provide references for healthy breeding. The infection of EHP in the breeding of Litopenaeus vannamei resulted in nutrient loss, retarded growth, uneven specification, and decreased productivity. The main causes of EHP pollution include seedling infection, water source carrying, biological food contamination, lax production management, and tail water discharge. In view of these reasons, the comprehensive preventive measures were put forward, including selecting and releasing high-quality shrimp seedlings and conducting regular epidemic inspection to ensure the quality of seedlings; the safety of water source should be ensured by disinfection of aquaculture water, proper water replenishment and sewage discharge, to ensure the safety of biological food through pathogen detection and disinfection; strictly disinfect the objects and production tools in the tank, and make full use of beneficial microbial preparations to strengthen production management; strictly treat aquaculture tail water to ensure harmless discharge. This paper provides a reference for the comprehensive prevention of Enterocytozoon hepatopenaei.
