Problems solved by technology

First of all, these drugs are generally highly irritating or corrosive, and have a great impact on the eating and growth of aquatic animals after use, directly affecting production performance; in addition, long-term use of parasites has produced drug resistance; moreover, these Substances are not easy to degrade in the environment, and are likely to cause water pollution. Some of them can also cause bioaccumulation, directly endangering human food safety and health.

Embodiment 1

[0016] The ectoparasite control agent for aquatic animals uses Cnidium fruit to extract and process Cnidium fruit extract, and the formula of the preparation is as follows: 20 parts of Cnidiac fruit extract, 5 parts of surfactant, and the rest are Ethanol or other solvents well known in the art constitute 100 parts; the surfactant is a mixture of dimethyl sulfoxide and Tween-80 in a ratio of 3:2.

[0017] The preparation method is as follows: weigh the crushed Cnidium fruit, extract with methanol under reflux at 60-70°C, concentrate the extract and evaporate the methanol to dryness, the extract is in the form of liquid extract, extract with anhydrous industrial alcohol, concentrate The extract is obtained Cnidium fruit concentrate;

[0018] Take 20kg of fruit concentrate, 5kg of mixture of surfactant dimethyl sulfoxide and Tween-80, and the rest is ethanol solvent, put them into a homogenizer, control the temperature at 50°C to 60°C, cool to normal temperature after processing...

Embodiment 2

[0020] The ectoparasite control agent for aquatic animals uses Cnidium fruit to extract and process the Cnidium fruit extract. The formulation of the preparation is in the following mass percentages: 50 parts of Cnidiac fruit extract, 5 parts of surfactant, and the rest is Ethanol or other solvents well known in the art constitute 100 parts; the surfactant is a mixture of dimethyl sulfoxide and Tween-80 in a ratio of 5:1. The preparation method is the same as in Example 1.

Embodiment 3

[0022] The ectoparasite control agent for aquatic animals uses Cnidium fruit to extract and process the Cnidium fruit extract. The formula of the preparation is as follows: 75 parts of Cnidiac fruit extract, 10 parts of surfactant, and the rest are Ethanol or other solvents well known in the art constitute 100 parts; the surfactant is a mixture of dimethyl sulfoxide and Tween-80 in a ratio of 5:1. The preparation method is the same as in Example 1.

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...
