Method for promoting development of ovaries of female Pelteobagrus fulvidraco

Abstract

The invention discloses a method for promoting the development of ovaries of female Pelteobagrus fulvidraco. The method includes the following steps: selecting high-quality female Pelteobagrus fulvidraco, performing breeding, maintaining white light irradiation for a period of time after each feed release, adding bactericide, mixing a traditional Chinese medicine preparation for preventing enteritis with feed, performing feeding, maintaining intermittent far infrared irradiation in a fish pond, adding a traditional Chinese medicine preparation for health care of ovaries, adjusting the water temperature in the fish pond to 27-28 DEG C, adding an ovulation promoting agent for fish feeding, mixing the female Pelteobagrus fulvidraco with male Pelteobagrus fulvidraco, performing breeding untilparturition of the female Pelteobagrus fulvidraco, putting the postpartum Pelteobagrus fulvidraco in the fish pond, maintaining alternate irradiation of infrared light and white light, and adding thetraditional Chinese medicine preparation for health care of ovaries to the feed so as to restore the ovaries quickly for the next reproduction. Through the method, the problem of gonadal dysgenesis caused by enteritis can be solved through simultaneous prevention and treatment of enteritis of Pelteobagrus fulvidraco, a health care effect on ovary development of the female Pelteobagrus fulvidraco can be achieved by the method, and economic benefits for breeding and production of Pelteobagrus fulvidraco can be achieved.

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
