Problems solved by technology

Cultivating shrimp seedlings that do not carry WSD is a way to prevent and control WSD. However, judging from the current high virus carrier rate of shrimp, it is very difficult to obtain broodstock that do not carry WSD
In addition, even though shrimp seedlings that do not carry WSD have been bred, it is still difficult to kill the virus remaining in the water and the environment in ponds where WSD disease has already broken out

Abstract

The present invention discloses a compound Chinese herbal medicine preparation for preventing and curing white spot disease (WSD) of procambarus clarkia and a method thereof. The compound Chinese herbal medicine preparation comprises the following components: radix isatidis, rheum officinale, herba houttuyniae and allicin. The method comprises the following steps: the compound Chinese herbal medicinal preparation is mixed with feed and the feed is continuously used to feed for 30-40 days before a season of an onset of the WSD of the procambarus clarkia. Compared with the prior art, especially for ponds which the WSD outbreak, the provided compound Chinese herbal medicine preparation for preventing and curing the WSD of the procambarus clarkia can control the incidence of the WSD of the procambarus clarkia to a very low level, the method is simple in operations, and the preparation has very important meanings for preventing and curing the WSD of the procambarus clarkia, reducing morbidity of the procambarus clarkia caused by the WSD, and improving yields.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a compound Chinese herbal medicine preparation for preventing and treating white spot syndrome of Procambarus clarkii and a method thereof. Background technique [0002] In recent years, white spot syndrome (White Spot Disease, WSD) has gradually become an important disease of farmed shrimp. The International Organization for Animal Health (OIE) lists WSD as a must-report disease, and the Ministry of Agriculture lists it as a first-class animal disease. Shrimp is prone to outbreaks of the disease from late April to early July, and the prevailing water temperature is 20-28°C. The climate is characterized by a large temperature difference between day and night on sunny days, continuous sunny days, the temperature rises rapidly, continuous cloudy days and heavy rains, the temperature drops rapidly, the water temperature is prone to drastic changes, and the physical and chemical...
