Embodiment 1

[0011] A compound immune enhancer for freshwater white pomfret seedlings, used as a feed additive for freshwater white pomfret seedlings, when the water temperature in the breeding pond is above 15°C, keep the dissolved oxygen in the seedling pond > 5mg / ml during the seedling raising process. Start to add after two days, the addition ratio in the feed is 0.3%, until the end of seedling cultivation;

[0012] The composite immune enhancer is composed of the following raw materials in parts by weight: 18 parts of peptidoglycan, 18 parts of chitin, 14 parts of glycyrrhizin, 6 parts of vitamin C, vitamin B 2 5 parts, 8 parts of lactoferrin, 10 parts of Grifola frondosa extract, 10 parts of Ganoderma lucidum polysaccharide, 5 parts of cypress polysaccharide, 4 parts of Huai Mi extract, 2 parts of Epimedium extract.

[0013] According to the statistics of emergence, the average value of emergence size is 23.5mm, and the survival rate is 84.5%.

Embodiment 2

[0015] A compound immune enhancer for freshwater white pomfret seedlings, used as a feed additive for freshwater white pomfret seedlings, when the water temperature in the breeding pond is above 12°C, keep the dissolved oxygen in the seedling pond > 5mg / ml during the seedling raising process. Start to add after two days, the addition ratio in the feed is 0.4%, until the end of seedling cultivation;

[0016] The composite immune enhancer is composed of the following raw materials in parts by weight: 24 parts of peptidoglycan, 16 parts of chitin, 12 parts of glycyrrhizin, 7 parts of vitamin C, vitamin B 2 4 parts, 5 parts of lactoferrin, 8 parts of Grifola frondosa extract, 10 parts of Ganoderma lucidum polysaccharide, 6 parts of cypress polysaccharide, 5 parts of Sophora japonica extract, 3 parts of Epimedium extract.

[0017] According to statistics of emergence, the average value of emergence size is 21.8mm, and the survival rate is 85.3%.

Embodiment 3

[0019] A compound immune enhancer for freshwater white pomfret seedlings, used as a feed additive for freshwater white pomfret seedlings, when the water temperature in the breeding pond is above 20°C, keep the dissolved oxygen in the seedling pond > 5mg / ml during the seedling raising process, Start to add after two days, and the addition ratio in the feed is 0.2%, until the end of seedling cultivation;

[0020] The composite immune enhancer is composed of the following raw materials in parts by weight: 20 parts of peptidoglycan, 14 parts of chitin, 15 parts of glycyrrhizin, 8 parts of vitamin C, vitamin B 2 5 parts, 6 parts of lactoferrin, 12 parts of Grifola frondosa extract, 6 parts of Ganoderma lucidum polysaccharide, 8 parts of cypress polysaccharide, 4 parts of Sophora japonica extract, 2 parts of Epimedium extract.

[0021] According to statistics of emergence, the average value of emergence size is 22.6mm, and the survival rate is 86.4%.

Abstract

The invention discloses a complex immunity enhancing agent for colossoma brachypomum fry breeding. The complex immunity enhancing agent for colossoma brachypomum fry breeding is used as a colossoma brachypomum fry feed additive. The complex immunity enhancing agent is prepared from, by weight, peptidoglycan, chitin, glycyrrhizin, vitamin C, vitamin, lactoferrin, maitake extracts, ganoderma polysaccharide, cypress fungus polysaccharide, sophora japonica extracts and epimedium extracts. Compared with the prior art, the complex immunity enhancing agent has the following advantages that raw materials in the composite immunity enhancing agent are stable in source, drug resistance caused when the same immunity agent is used within a long time can be effectively avoided, and meanwhile the complex immunity enhancing agent can be completely degraded under the natural condition and is free of residue in fry; by means of the immunity enhancing agent, it can be kept that the temperature of breeding pond water is 12 DEG C or above, it is guaranteed that fry breeding immunity is good, the fry producing specification and the fry survival rate are increased, the colossoma brachypomum fry breeding period is prolonged, and breeding cost is reduced to a certain extent.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a compound immune enhancer for raising freshwater pomfret seedlings. Background technique [0002] Freshwater pomfret has the characteristics of omnivorous, fast growth, large individual, less disease, easy to catch, thick meat and less thorns, delicious taste, rich nutrition, etc. Due to the accumulation and promotion of freshwater pomfret breeding experience, it has become the highest annual output in my country. One of the special varieties. [0003] When freshwater pomfret seedlings are raised, the general survival rate is relatively low. Now, in order to improve the survival rate of freshwater white pomfret seedlings, amino acid water fertilizers are usually added to the pool water, and the temperature of the pool water is kept at 18-23°C to increase feed nutrition or increase fry activity. Space and dissolved oxygen, although the survival rate of white pomfr...
