Embodiment 1

[0022] Feed for ornamental fish, consisting of:

[0023] Shrimp and crab shell powder 5wt%

[0024] Fishmeal 20wt%

[0025] Photosynthetic bacteria 1wt%

[0026] Microalgae Concentrate 1wt%

[0027] Flour 73wt%.

[0028] Among the above-mentioned raw materials, shrimp and crab shell powder, fish meal, and flour are easy to get, photosynthetic bacteria are commercially available, and microalgae concentrates are commercially available. Microalgae can also be used as raw materials to extract their active substances with ethanol-ultrasound, and then the rich polysaccharides The ethanol liquid of the beneficial substance is obtained by recovering the ethanol in a distillation device.

[0029] The preparation method of the above-mentioned ornamental fish feed is as follows: first boil the flour into a paste, then mix in shrimp and crab shell powder, fish meal, photosynthetic bacteria and microalgae concentrate, mix well, extrude through a feed extruder, and dry to form granules,...

Embodiment 2

[0031] Feed for ornamental fish, consisting of:

[0032] Shrimp and crab shell powder 10wt%

[0033] Fishmeal 25wt%

[0034] Bacillus subtilis 2wt%

[0035] Microalgae Concentrate 1wt%

[0036] Flour 62wt%.

[0037] Among the above-mentioned raw materials, shrimp and crab shell powder, fish meal, and flour are easy to get. Bacillus subtilis is commercially available and can be inoculated for production. Then the ethanol liquid rich in various beneficial substances is recovered in a distillation device to obtain the ethanol.

[0038] The preparation method of the above-mentioned ornamental fish feed is as follows: first boil the flour into a paste, then mix in shrimp and crab shell powder, fish meal and microalgae concentrate, mix well, extrude through a feed extruder, and dry to form granules. Moisture content does not exceed 7%.

Embodiment 3

[0040] Feed for ornamental fish, consisting of:

[0041] Shrimp and crab shell powder 15wt%

[0042] Fishmeal 30wt%

[0043] Bacillus subtilis 2wt%

[0044] Microalgae Concentrate 3wt%

[0045] Flour 50wt%.

[0046] Among the above-mentioned raw materials, shrimp and crab shell powder, fish meal, and flour are easy to get. Bacillus subtilis is commercially available and can be inoculated for production. Then the ethanol liquid rich in various beneficial substances is recovered in a distillation device to obtain the ethanol.

[0047] The preparation method of the above-mentioned ornamental fish feed is as follows: first boil the flour into a paste, then mix in shrimp and crab shell powder, fish meal and microalgae concentrate, mix well, extrude through a feed extruder, and dry to form granules. Moisture content does not exceed 7%.

Abstract

The invention relates to an ornamental fish feed, and belongs to the technical field of ornamental fish culture. The ornamental fish feed consists of the following substances: 5 to 25 weight percent of shrimp or crab shell powder, 20 to 50 weight percent of animal protein powder, 1 to 2 weight percent of beneficial active microbe, 1 to 10 weight percent of microalgae concentrate and the balance of flour. The ornamental fish feed has comprehensive nutrition, is rich in astaxanthin serving as a natural pigment, can provide comprehensive nutrition for ornamental fish, and can also provide pure natural astaxanthin for the ornamental fish so that the fish has bright and durable luster.

Description

technical field [0001] The invention relates to a feed for ornamental fish, which belongs to the technical field of ornamental fish breeding. Background technique [0002] Compared with natural bait, artificial feed has the following advantages: First, the source is relatively stable and can be produced continuously throughout the year, while natural bait is easily restricted by seasons; second, it can be produced according to different stages of fish growth and development. The feed formula can be adjusted at any time for different nutritional needs, which not only meets the nutritional needs of fish at different stages, but also reduces the cost of breeding; third, a certain amount of drugs can be added according to seasonal changes to prevent and treat some common fish diseases; fourth, it can be passed through high temperature Treatment can kill some pathogenic bacteria. The body color of ornamental fish is significantly different from that of general edible fish, and t...
