Embodiment Construction

[0006] The method for artificial breeding of Changchun bream is characterized in that it includes the following steps: 1). Source of broodstock: Breeding broodstock is Changchun bream domesticated by Guanjiang Namiao or wild Changchun bream caught; 2). Breeding of broodstock: a. Cultivation in still water: Select backup broodstock with strong physique, good vitality, complete fin scales, no injury and disease, and put them in a still water pond with an area of ​​more than 4 mu, with a stocking density of 400-500 tails / mu; after the backup broodstock enters the pond, 3 b. Intensive cultivation of running water in the later period: in the winter of the second year, transfer the reserve broodstock from the static water pond to the running water pond of more than 6 mu for cultivation, and the stocking density is 300-350 fish / mu; At the beginning, the water pool was flushed 2-3 times a week, 5-6 hours each time; after half a year of intensive cultivation, the gonads of male and fem...

Abstract

The invention relates to a method for artificially propagating parabramis pekinensis. The method comprises the following steps of: 1) selecting the source of parent fish; 2) breeding the parent fish; 3) artificially spawning and performing insemination, namely a) selecting the parent fish, b) collecting semen, taking eggs and checking, c) matching, d) setting water temperature of spawning, e) injecting odinagogue, and f) laying eggs; and 4) performing hatching management. By the means of enhancement of parent fish nutrient enhancement cultivation, flowing water stimulation regulation and the like, the gonad development and maturation of the parent fish and discharge can be promoted, the artificial spawning and insemination processes are standardized, the technical problem in the artificial propagation of parabramis pekinensis is effectively solved, the spawning rate of artificial propagation is 89 percent, the fertility rate is 83 percent, and the hatching rate is 83.5 percent. The method is easy and convenient to operate and high in applicability and can meet the requirement on the industrial batch propagation.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for artificial propagation of Changchun bream. Background technique [0002] Changchun bream is distributed in major water systems across the country. It has a slender body, delicious meat, and low fat content. It is a high-quality medium-sized economic fish. However, Changchun bream is a freshwater fish species suitable for breeding and development, and the research is obviously lagging behind. So far, there has been no report on the artificial breeding method of Changchun bream. The invention mainly solves the method for breeding Changchun bream under the condition of artificial control, achieves the purpose of stably producing Changchun bream seedlings, and lays a seedling foundation for popularizing and cultivating Changchun bream. Contents of the invention [0003] The purpose of the present invention is to provide a method for artificial reproduction of Cha...
