External parasite preventing and treating agent for aquatic product animals and its preparing method

Abstract

The external parasite preventing and treating preparation for aquatic animals consists of cnidium fruit extract, alcohol or other solvent, and surfactant. The preparation process includes crushing cnidium fruit, reflux extraction with methanol, concentrating the extracted liquid, extraction with industrial alcohol to obtain the concentrated extracted liquid, mixing the cnidium fruit extract, surfactant and alcohol or other solvent in a homogenizer at 50-60 deg.c, cooling to normal temperature to obtain the preparation. The preparation has obvious killing effect on extracorporeal parasites of aquatic animals, no pollution, less drug resistance, low cost, and other advantages.

Description

technical field

[0001] The invention belongs to an insecticide and an insect-repellent agent in the aquaculture industry, relates to a control agent, in particular to an aquatic animal ectoparasite control agent prepared from Cnidium chinensis extract. Background technique

[0002] The prevention and control of aquatic animal parasites is an important guarantee measure for the economic benefits of aquaculture. The incidence of parasitic diseases in aquatic animals is high and widespread. Among them, the most harmful ectoparasites include protozoa such as trichomonas and melon worms; worms such as ring worms and third-generation worms; At present, insecticides such as dichlorvos, acephate, malachite green, and mercurous nitrate have been banned in aquatic products due to poor safety, environmental pollution, and potential harm to humans. At present, chemical agents such as mebendazole, praziquantel, betin, abamectin, formalin, trichlorfon, pyrethroids, dye methylene blue, an...
