Problems solved by technology

[0007] The primary purpose of the present invention is to overcome and solve the problem that crustaceans (comprising Chinese bream, anchorhead bream, fish carp, etc.) have drug resistance to existing drugs or existing drugs are highly toxic to fish, and long-term use will cause fish appetite and immunity. The disadvantages and problems of reducing energy, affecting the healthy growth of fish, and causing harm to humans and the ecological environment, etc., provide a drug for preventing and treating fish parasitic crustacean diseases

Abstract

The invention discloses a medicine for preventing fish parasitic crustacean diseases, a preparation method and an application thereof. The method comprises the following steps that pyridaben with masspercentage of between 5 and 30 percent and a surface active agent with mass percentage of between 5 and 25 percent are mixed; after the mixture is stirred for 25 to 35 minutes at a temperature of between 25 and 35 DEG C under 280-320rpm, a 45 to 90 percent solvent is added into the mixture to be stirred for 25 to 35 minutes to prepare the medicine for preventing the fish parasitic crustacean diseases. The method successfully applies pyridaben to the preparation of the medicine for preventing fish parasitic crustacean diseases for the first time. The medicine for preventing fish parasitic crustacean diseases has simple preparation process and easy operation, good effect, small dosage, long lasting period, safe for fish and non-pollution to ecological environment.

Description

technical field [0001] The invention belongs to the technical field of preparation of biochemical drugs for fish, and in particular relates to a drug for preventing and treating fish parasitic crustacean diseases, a preparation method and application thereof. Background technique [0002] Aquatic animal diseases caused by parasitism of crustaceans (including Chinese bream, anchorhead bream, fish carp, etc.) are collectively referred to as parasitic crustacean diseases. It can not only directly cause growth stagnation or mass death of diseased fish, but also indirectly increase the chances of aquatic animals suffering from bacterial and viral diseases, causing huge losses to the aquaculture industry. [0003] Chinese gnats belong to the subclass Copepoda, the order Cyclopsidae, and the family Ichthyidae. They occur in my country from Heilongjiang in the north to Guangdong in the south. The disease is most prevalent from late May to early September. The sinensis mainly harms ...
