Mixed feed for juvenile fishes of oreochromis sp and preparing method thereof

Abstract

The invention relates to fish feed, in particular to mixed feed for juvenile fishes of oreochromis sp. The invention further relates to a preparing method for the mixed feed for the juvenile fishes of the oreochromis sp. The mixed feed for the juvenile fishes of the oreochromis sp comprises, by mass, 18-29 parts of fish meal, 5-15 parts of soybean straw, 6-12 parts of salvinia natans powder, 5-12 parts of dry green grass powder, 3-8 parts of rhizoma phragmitis, 2-7 parts of common dayflower herbs, 2-6 parts of oysters, 3-7 parts of poria cocos, 2-5 parts of platycladi seeds, 2-6 parts of rhizoma corydalis, 1-5 parts of fructus alpiniae oxyphyllae, 1-4 parts of angelica sinensis, 2-6 parts of fish oil, 1-4 parts of honey, 1-4 parts of olive oil and 1-4 parts of gypsum. After the juvenile fishes of the oreochromis sp are fed on the mixed feed, the survival rate of the juvenile fishes of the oreochromis sp is high, the feed coefficient is low, the specific growth rate is high, and the disease resisting ability is high.

Description

technical field [0001] The invention relates to a fish feed, in particular to a compound feed for juvenile silver tilapia Xingzhou; the invention also relates to a preparation method of the compound feed for juvenile silver tilapia Xingzhou. Background technique [0002] Xingzhou silver tilapia (Oreochromis sp.) is an excellent new species of tilapia with relatively stable genetic traits selected from the offspring of Taiwan red tilapia from the intermediary hybrid of tilapia (Oreochromis niloticus × ​​O. mossambicus). Introduced from Singapore in 1998, the fish is pink in color, white and tender in flesh, without intermuscular thorns, and its taste is comparable to that of American sea bass and sweet-scented osmanthus fish.

AI Technical Summary

Problems solved by technology

[0003] At present, during the breeding process of juvenile silver tilapia, due to continuous fertilization and bait feeding, the remaining feces and residual bait are most likely to damage the water quality, which often causes diseases in juvenile silver tilapia. When dealing with fish diseases, the method of splashing bactericidal disinfectants is often used according to the disease, but the drugs will more or less have side effects or toxicity. Although they can kill pathogenic bacteria on the surface of juvenile fish and in the water, they often cause water pollution. And long-term use will cause the accumulation of drugs, affecting the health of the body, and then affecting the growth rate of juvenile silver tilapia in Sin Chew

Juvenile Sin Chew silver tilapia often suffers from lack of resistance due to insufficient nutrition during the growth process, resulting in various fish diseases, which affect the survival rate of Sin Chew silver tilapia. A compound feed that can ensure the resistance of feed quality and is conducive to the growth and development of juvenile fish is an urgent problem to be solved in the Sin Chew silver tilapia aquaculture industry.
