[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 ar

Abstract

The invention belongs to the technical field of culture of yellow catfishes and particularly relates to a culture method for promoting ovarian development of female parents of the yellow catfishes. The method specifically includes the following steps of 1, feeding the yellow catfishes with first yellow catfish feed every day at 6:40, feeding the yellow catfishes with second yellow catfish feed every day at 13:30, and feeding the yellow catfishes with third yellow catfish feed every day at 20:20, wherein the weight of the first yellow catfish feed is 1.1-1.2% of that of the yellow catfishes, the weight of the second yellow catfish feed is 0.6-0.7% of that of the yellow catfishes, and the weight of the third yellow catfish feed is 0.8-0.9% of that of the yellow catfishes; 2, using blue lightwith the light intensity of 140-150 Lx for light supplementation illumination treatment every day at 1:30 to 4:10, and using blue light with the light intensity of 210-220Lx for light supplementationillumination treatment every day at 20:50 to 23:20. By means of the method, the development and early maturation of gonads of the yellow catfishes can be effectively promoted, digestion, absorption and conversion capabilities of the female parents of the yellow catfishes on the feed are promoted, the growth performance of the female parents of the yellow catfishes is enhanced, the high yield andquality of the female parents of the yellow catfishes are promoted, and economic benefits of culture of the yellow catfishes are increased.
