Abstract

The invention relates to a bacteriostatic debonding agent, a preparation method thereof and a method for increasing the artificial breeding hatching rate of leuciscus waleckii by using the bacteriostatic debonding agent, and belongs to the technical field of aquaculture. In order to solve the problems of low artificial breeding hatching rate and low survival rate of the leuciscus waleckii, the invention provides the bacteriostatic debonding agent which is mainly composed of an adsorptive carrier and bacteriostaticcomponents loaded on the carrier, and the bacteriostatic components are mainly composed of gallnut, scutellaria baicalensis, radix sophorae flavescentis, honeysuckle, fructus forsythiae and acorus calamus. The method for increasing the artificial breeding hatching rate of the leuciscus waleckii by using the bacteriostaticdebonding agent comprises the steps of artificial fertilization, fertilized egg debonding, water mildew prevention and treatment, hatching and fry raising. The bacteriostatic and debonding micron-sized adsorptive carrier is good in debonding effect, fertilized eggs can be separated from one another, and the hatching rate of the fertilized eggs is increased; and the traditional Chinese medicine effective components loaded on the adsorptive carrier can inhibit invasion of saprolegniasis spores and other bacteria, saprolegniasis breeding is prevented, and the survival rate of fries is increased.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to an antibacterial and debonding agent, a preparation method thereof and a method for improving the hatching rate of artificial breeding of crocodile vacheronii by using the antibacterial and debonding agent. Background technique [0002] The yarrow is a fish belonging to the Cyprinidae family and the genus Yaluo. It has a long body, flat sides, a slightly curved back, and a round belly. The crocodile is a pelagic fish in the northern plains of China, and often lives in calm water areas. Although it is not a cold-water fish, it prefers to live in the middle and upper layers of river mouths or mountain tributaries with slow water flow, sandy bottom and clear water quality. It can also live in brackish water lakes, and it is rare in completely still water. [0003] It is listed as an important economic fish in Northeast China and the middle reaches of the Yellow Rive...
