Embodiment 1

[0015] An immune-boosting bait for preventing sturgeon septicemia, which is prepared by mixing the following components by weight: 20% fish meal, 20% bean curd, 35% autolyzed yeast powder, 12.945% beta-glucan, and 12% mannoprotein %, yeast selenium 0.01%, yeast chromium 0.005%, Bacillus subtilis 0.04%, wherein the autolyzed yeast powder comes from baker’s yeast, and the autolyzed yeast powder contains 0.5% reduced glutathione, β-glucose The content of β-(1,3) glucan in the polysaccharide is 75%, the content of organic selenium in the yeast selenium is 0.2%, and the content of organic chromium in the yeast chromium is 0.8%, and the above-mentioned components are mixed uniformly to prepare Granular immune enhancement bait with a particle size of 0.6 mm.

Embodiment 2

[0017] An immune-boosting bait for preventing sturgeon septicemia, which is prepared by mixing the following components by weight: 30% fish meal, 25% bean curd, 15% autolyzed yeast powder, 20% β-glucan, and 9.91% mannoprotein %, yeast selenium 0.02%, yeast chromium 0.01%, Bacillus subtilis 0.06%, wherein the autolyzed yeast powder comes from baker’s yeast, and the autolyzed yeast powder contains 1.2% reduced glutathione, β-glucose The content of β-(1,3) glucan in the polysaccharide is 50%, the content of organic selenium in the yeast selenium is 0.1%, and the content of organic chromium in the yeast chromium is 0.25%, and the above-mentioned components are mixed uniformly to prepare Granular immune enhancement bait with a particle size of 0.8mm.

Embodiment 3

[0019] An immune-boosting bait for preventing sturgeon septicemia, which is prepared by mixing the following components by weight: 30% fish meal, 30% bean curd, 20% autolyzed yeast powder, 12% β-glucan, and 7.92% mannoprotein %, yeast selenium 0.02%, yeast chromium 0.01%, Bacillus subtilis 0.05%, wherein the autolyzed yeast powder comes from baker’s yeast, and the autolyzed yeast powder contains 0.8% reduced glutathione, β-glucose The content of β-(1,3) glucan in the polysaccharide is 60%, the content of organic selenium in the yeast selenium is 0.15%, and the content of organic chromium in the yeast chromium is 0.4%, and the above-mentioned components are mixed uniformly to prepare Granular immune enhancement bait with a particle size of 0.7 mm.

[0020] 2,000 healthy sturgeons with a weight of 23±2g were randomly divided into four groups and put into 4 breeding ponds A, B, C, and D. 500 fish were put into each breeding pond. The breeding pond was a circular glass fiber reinf...

Abstract

The invention relates to sturgeon bait, in particular to immunological enhancement bait for preventing septicemia of sturgeon, which aims to overcome the defect in the prior art that no immunological enhancement bait is used for preventing septicemia of sturgeon. The immunological enhancement bait for preventing septicemia of sturgeon is prepared by mixing the following components by weight percentage: 20-50% of fish meal, 20-40% of bean pulp, 15-35% of self-soluble yeast powder, 10-20% of beta-glucan, 5-12% of mannoprotein, 0.01-0.02% of yeast selenium, 0.005-0.01% of chromium yeast and 0.04-0.06% of bacillus grass. The immunological enhancement bait for preventing septicemia of sturgeon has the advantages of reasonable compatibility of medicines, balanced nutrition, low processing cost, good palatability and attractant performance, high utilization ratio of sturgeon and less metabolic waste, and the immunity of sturgeon is remarkably improved, and the probability of infecting septicemia of sturgeon is greatly reduced.

Description

technical field [0001] The invention relates to a sturgeon bait, in particular to an immune enhancing bait for preventing sturgeon septicemia. Background technique [0002] Sturgeon is a high-quality cold-water fish, and wild sturgeon resources are close to depletion. It is a very urgent task to carry out value-added resources and artificial breeding of sturgeon. It is difficult to cure with common medicines and sturgeons are extremely sensitive to common medicines. Sturgeon sepsis is mainly caused by Aeromonas hydrophila, which belongs to the genus Aeromonas of the Vibrio family. The exotoxins in the sturgeons infected with septicemia have less food intake, weak constitution and high mortality, which are problems to be solved urgently in the artificial breeding of sturgeons. Improving the immunity of sturgeon itself can greatly reduce the chance of infection with sepsis. At present, there is a lack of an immune-boosting bait to prevent sturgeon sepsis.
