Problems solved by technology

[0002] EHP (Enterospora hepatica) of Penaeus vannamei is the number one disease in the breeding and breeding of Penaeus vannamei in recent years, which has affected the global shrimp farming industry and greatly reduced production, and nursery enterprises and farmers have suffered greatly from it; at present, there is no single product at home and abroad Or the reference that the treatment process can completely solve the disease
[0003] The killing method and technology of EHP (Enterocystoma hepatica) of Penaeus vannamei, hereinafter referred to as "EHP killing technology", can be completely killed at the seedling stage and high-density environment at present, and the low-density large-area adult shrimp culture is due to cost factors. Can only be controlled within a safe range

Abstract

The invention relates to a method for killing EHP (Enterocytozoon hepatopenaei) on Penaeus vannamei. The method comprises the steps: mixing essential oil into shrimp feed firstly, feeding Penaeus vannamei for two days or above, performing water change and pollution discharge after feeding on a culture pond two times or above in the feeding period, and performing medicated bath by using a sea saltelectrolytic solution-aqueous chlorine dioxide preparation so as to kill and eliminate EHP on Penaeus vannamei successfully. The domestic and foreign EHP treatment technology is supplemented, the economic benefits are high, the killing effect on EHP is fast, the operation is simple, and promotion is quick and convenient.
