Breeding method for parent misgurnus anguillicaudatus

Abstract

The invention discloses a breeding method for parent misgurnus anguillicaudatus and relates to the field of aquaculture. The method comprises the following steps: selecting the parent misgurnus anguillicaudatus from a last-year artificial cultivation pond, wherein female misgurnus anguillicaudatus is over 3 years old, male misgurnus anguillicaudatus is over two years old, the body length of the misgurnus anguillicaudatus is 15-20 cm, the average body weight is over 12 g, the quantity ratio of the female misgurnus anguillicaudatus to the male misgurnus anguillicaudatus is 1:(2-3), the area of a parent misgurnus anguillicaudatus cultivation pond is 0.17 hectare, the water depth is 50-60 cm, and the depth of soft sapropel at the bottom of the pond is 15 cm; arranging an anti-escaping net at a water inlet / outlet, wherein water is required to be clear and pollution-free, the released density is 25 misgurnus anguillicaudatus per square meter, and the putting volume is 37.50 kg / hectare; before the parent misgurnus anguillicaudatus is put into the cultivation pond, treating pond water by using a traditional Chinese medicine composition. According to the breeding method for the parent misgurnus anguillicaudatus provided by the invention, by virtue of breeding and strengthened cultivation, the physical health of the parent misgurnus anguillicaudatus is improved, the brood amount is large, and the spawning induction fertilization rate is high. Moreover, the pond water in the cultivation pond is treated by using the traditional Chinese medicine composition, germs and parasites in a water body are killed, the traditional Chinese medicine composition can promote the misgurnus anguillicaudatus to forage, and the aim of cultivation induction is achieved.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a method for breeding loach parents. 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. Through selective breed...
