Breeding fish feed for barbus dabryanus and application of breeding fish feed in artificial breeding of barbus dabryanus

Abstract

The invention provides a barbus dabryanus breeding fish feed and an application thereof in artificial breeding of barbus dabryanus. The fish feed comprises a Chinese herbal medicine additive, wherein the Chinese herbal medicine additive comprises the following raw materials in parts by weight: 2-6 parts of castor seed kernels, 10-20 parts of houttuynia cordata, 5-15 parts of wild chrysanthemum flowers, 5-10 parts of semen allii tuberosi, 10-20 parts of motherwort and 10-25 parts of schisandra chinensis. The barbus capito parent fish feed provided by the invention has relatively strong sterilization and bacteriostasis effects, is beneficial to enhancing the immunity and disease prevention and resistance of barbus capito parent fish, can also improve the digestion and absorption capacity and growth and development of barbus capito parent fish, can remarkably promote gonad development and maturation, shortens the gonad maturation time, improves the survival rate of barbus capito parent fish, improves the survival rate of barbus capito parent fish, and improves the survival rate of barbus capito parent fish. The brood amount and the ovulation amount are effectively increased, and the quality of ova is improved, so that the reproductive capacity of the barbus capito parent fish is enhanced. The fish feed has extremely important significance in artificial cultivation of the barbus dabryanus.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a fish feed for catfish species and its application in artificial cultivation of catfish. Background technique [0002] Large scale barb is a common edible fish in Xishuangbanna, Yunnan. Its meat is tender and delicious. It is a common economic fish in the local area. It is deeply loved by consumers and has high promotion value. With the increasing market demand, the scale of aquaculture of large scale barb is gradually expanding. However, due to the low and unstable reproductive efficiency of the giant catfish, the supply of seed is seriously insufficient. At present, in order to alleviate the problem of insufficient number of seedlings, the method of adding chemical hormones and other drugs to the feed is often used to promote the maturation of the gonads of the catfish and enhance its reproductive ability. However, long-term use of this feed will not only reduce the quality of see...

AI Technical Summary

Problems solved by technology

[0004] Under natural conditions, the maturation time of the gonads of the giant catfish is longer, and the amount of fecundity and ovulation is lower, which leads to a decrease in the fertilization rate and reproductive capacity of the catfish

In addition, with the rapid development of large-scale and intensive farming of fish, outbreaks of aquaculture diseases caused by bacterial and viral infections are becoming more and more frequent, which will seriously affect the reproduction of fish species and reduce the quality of seedlings. In order to control diseases Usually, chemical drugs, antibiotics and other substances are added to the breeding fish feed to improve the immunity of the breeding fish and further improve their reproductive ability, but these substances are easy to cause residues, which will affect the health of the human body after eating
