Early-stage cultivation method for hatched young misgurnus anguillicaudatus

Abstract

The invention discloses an early-stage cultivation method for hatched young misgurnus anguillicaudatus and relates to the field of aquaculture. Within three days after young misgurnus anguillicaudatus is hatched, all yolks disappear, mouth parts are formed, and boiled egg yolks start to be fed by a person. The method comprises the following steps: boiling eggs, taking out the egg yolks, and filling the egg yolks in a 120-mesh silk bag for pinching and washing; splashing an egg yolk suspension, and feeding the young misgurnus anguillicaudatus, wherein water flow in a loop for hatching the young misgurnus anguillicaudatus decelerates during feeding, the feeding amount of the young misgurnus anguillicaudatus on the first day is 10 / 1000,000, the feeding amount of the young misgurnus anguillicaudatus on the second day is 15 / 1000,000, and the feeding amount of the young misgurnus anguillicaudatus on the third day is 20 / 1000,000; feeding the young misgurnus anguillicaudatus for four times every day; after the young misgurnus anguillicaudatus is fed for three days and the color of the young misgurnus anguillicaudatus body changes from black into light yellow, taking the misgurnus anguillicaudatus out of a pond, and performing summer flower cultivation. The method is simple in operation process; the quick growth of the young misgurnus anguillicaudatus can be promoted; the young misgurnus anguillicaudatus is fed with the egg yolks and soybean milk, the growth of zooplankton in a water body inside a cultivation pond can be promoted, and the zooplankton can serve as natural baits of the young misgurnus anguillicaudatus; with milk powder added into the soybean milk and a traditional Chinese medicine composition water extract, the growth of the young misgurnus anguillicaudatus can be promoted, the resistance of the young misgurnus anguillicaudatus can be improved, the stress response to the environment is reduced, and the survival rate of the young misgurnus anguillicaudatus is improved.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a pre-cultivation method for loach seedlings after hatching. Background technique [0002] Loach (Misgurnus anguillicaudatus) has high nutritional and medicinal value. It has a large demand in the domestic and foreign markets, and the price is relatively good. The artificial breeding has high profits and quick results, and the breeding prospect is promising. The breeding area of ​​loach in China is 15 million to 20 million square meters, mainly concentrated in Jiangsu, Henan, Hubei, Shandong, Anhui and Sichuan, and the breeding mode is mainly pond seine farming with soil. At present, the main factor restricting the benefit of loach breeding is that the growth rate of loach is slow, and the annual growth rate is difficult to reach more than 3 times; parent selection and intensive cultivation of loach are one of the more important and key technical links in artificial breeding of loach. ...

AI Technical Summary

Problems solved by technology

After the loach seedlings are hatched from loach spawning, the loach seedlings need to be carefully reared and managed. At present, in the artificial breeding technology of loach, the early cultivation technology of loach seedlings is immature, and the mortality rate of loach seedlings is relatively high.
