Xenocypris davidi fry mixed feed and preparation method thereof

Abstract

The invention relates to a fish feed, especially relates to a xenocypris davidi fry mixed feed, and also relates to a preparation method of the xenocypris davidi fry mixed feed. The mixed feed comprises the following components in parts by weight: 18 to 27 parts of fish meal, 7 to 15 parts of straw powder, 6 to 13 parts of cotton meal, 5 to 12 parts of rice bran, 3 to 8 parts of polygonum perfoliatum, 2 to 7 parts of magnolia cortex, 2 to 6 parts of gentian, 3 to 7 parts of cortex fraxini, 2 to 5 parts of Chinese holly, 2 to 6 parts of ginger, 2 to 6 parts of fish oil, 1 to 5 parts of diatom powder, 1 to 4 parts of lotus seed powder, 1 to 4 parts of honey, 1 to 4 parts of olive oil, and 1 to 4 parts of mixed multiple vitamins. The mixed feed has the advantages of high living rate, low feed coefficient, high specific growth rate, and strong disease resistant performance.

Description

technical field [0001] The invention relates to a fish feed, in particular to a compound feed for juvenile yellow-tailed pomfret fish; the invention also relates to a preparation method of the above-mentioned compound feed for juvenile yellow-tailed pomfret fish. Background technique [0002] Yellow-tailed pomfret (scientific name: Xenocyprisdavidi) is a fish of the family Cyprinidae. It is a small and medium-sized fish that grows in the middle and lower layers of freshwater bodies. It is a transverse split, with a well-developed horny edge on the lower jaw; the back is gray, the abdomen is white, there is a light yellow patch on the rear edge of the operculum, the caudal fin is orange, and it mainly feeds on plant debris, humus and algae on the bottom, ponds Breeding can be fed bran, bran, etc. [0003] At present, during the breeding process of juvenile yellow-tailed pomfret, due to continuous fertilization and feeding, the remaining feces and residual bait are most likel...

AI Technical Summary

Problems solved by technology

[0003] At present, during the breeding process of juvenile yellow-tailed pomfret, due to continuous fertilization and feeding, the remaining feces and residual bait are most likely to damage the water quality, which often causes diseases in juvenile yellow-tailed pomfret. When people deal with fish diseases, The method of splashing bactericidal disinfectant is often used according to the condition, but the drug will more or less produce side effects or toxicity. Although it can kill pathogenic bacteria on the surface of juvenile yellow-tailed pomfret fish and in the water, it often causes water pollution, and long-term use It will cause the accumulation of drugs, affect the health of the body, and then affect the growth rate of juvenile yellow-tailed pomfret

Juvenile yellow-tailed pomfret often suffer from lack of resistance due to insufficient nutrition during the growth process, resulting in various fish diseases, which affect the survival rate of yellow-tailed pomfret. The compound feed for yellow-tailed pomfret juveniles with high quality and good for the growth and development of yellow-tailed pomfret juveniles is an urgent problem to be solved in the current yellow-tailed pomfret breeding industry
