A method for promoting the development of female ovary of yellow catfish

Abstract

The invention discloses a method for promoting the development of female ovaries of yellow catfish, which comprises the following steps: selecting high-quality female yellow catfish for feeding, and keeping white light irradiation for a period of time after feeding each time; putting fungicides, and preventing enteritis Mix the traditional Chinese medicine preparations into the feed; keep intermittent far-infrared irradiation in the fish pond, and add ovarian health care Chinese medicine preparations; adjust the water temperature in the pool to 27-28°C, add ovulation-stimulating agents to feed, and mix with male yellow catfish Breeding to wait for its production; place the produced yellow catfish alone in the fish pond, keep infrared light and white light alternately irradiated, and add ovarian health care Chinese medicine preparations to the feed to make the ovaries recover quickly for the next reproduction. The method provides a method capable of simultaneously preventing and treating the problem of hypogonadism caused by enteritis of the yellow catfish, and the method has a health care effect on the ovarian development of the female yellow catfish, and has economic benefits for the culture and production of the yellow catfish.

Description

technical field [0001] The invention relates to the technical field of raising fish seedlings, in particular to a method for promoting the development of the female ovary of yellow catfish. Background technique [0002] The yellow catfish belongs to the Siluriformes, the family Pleurotus, and the genus of the yellow catfish. It is a high-quality and valuable economic fish in freshwater waters. It is loved by people because of its delicious meat. Artificial culture of yellow catfish has been carried out in many parts of the country, and the scale of farming has increased year by year. In 2015, the farming output of yellow catfish in my country exceeded 350,000 tons; It can cause a variety of diseases, resulting in high mortality and unstable yield. Broodstock cultivation is an important link in fish artificial reproduction. During the broodstock cultivation period, enteritis disease will seriously affect the growth and gonad development of broodstock, and then affect the qualit...

[0002] The yellow catfish belongs to the Siluriformes, the family Pleurotus, and the genus of the yellow catfish. It is a high-quality and valuable economic fish in freshwater waters. It is loved by people because of its delicious meat. Artificial culture of yellow catfish has been carried out in many parts of the country, and the scale of farming has increased year by year. In 2015, the farming output of yellow catfish in my country exceeded 350,000 tons; It can cause a variety of diseases, resulting in high mortality and unstable yield. Broodstock cultivation is an important link in fish artificial reproduction. During the broodstock cultivation period, enteritis disease will seriously affect the growth and gonad development of broodstock, and then affect the quality of high-quality seedlings. Large-scale production has brought great adverse effects on the breeding of yellow catfish, greatly reducing the economic benefits of yellow catfish farming; moreover, the recovery of the ovary of the broodstock of yellow catfish is slow after breeding, and it takes a long time to carry out the next round of breeding. Reproduction, therefore, need to improve the method of ovarian development of the female parent of yellow catfish, and then improve the economic benefit of yellow catfish culture production
