Cultivation induction method for parent misgurnus anguillicaudatus

Abstract

The invention discloses a cultivation induction method for parent misgurnus anguillicaudatus and relates to the field of aquaculture. The method comprises the following steps: treating pond water in a cultivation pond by using a traditional Chinese medicine composition; putting the bred parent misgurnus anguillicaudatus into the cultivation pond, and cultivating the parent misgurnus anguillicaudatus with self-made feeds, wherein animal proteins and plant proteins account for 50 percent respectively, the content of the proteins is 35 percent, and the content of fat is 5 percent; feeding the parent misgurnus anguillicaudatus for two times every day, wherein the feeding amount is 3-5 percent of the body weight of the parent misgurnus anguillicaudatus, water is yellow green and keeps rich and clear, the transparency is 15-20 cm, and the water temperature is 15-25 DEG C; washing for two times every week, changing a quarter of pond water at each time, dissecting regularly to check gonad development, timely adjusting a work plan, and preventing the putrid-skin disease, the edema disease, the trichodiniasis, the chilodonelliasis and the bird damage of misgurnus anguillicaudatus. According to the cultivation induction 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...
