Problems solved by technology

As a kind of ornamental fish, it is necessary to improve its body color as much as possible during the breeding process, specifically to make the color patches on the fish body more vivid. The existing bait for improving the body color of koi is mainly used in conventional bait The way of adding spirulina, as disclosed in CN201110324560.9, is a compound bait that makes the body color of koi brightly colored. The amount of spirulina prescribed above can supplement a certain amount of carotenoids during the growth of koi carp so as to improve its body color to a certain extent, but too high a content of spirulina does not match the nutrition required for koi carp growth. As a result, under the condition of using this bait alone, the immunity of koi is poor, and it is easy to be infected with various fish diseases

Affect the ornamental effect and the economic loss of koi breeding

CN201310140609.4 discloses a special bait for color-enhancing koi fish, which uses 0.1-5% by weight of spirulina, and CN201510059802.4 discloses a kind of bait for red and white koi fish, which uses 6-7% by weight of spirulina , in actual use, we found that these two formulas reduced the content of spirulina, which first caused a decline in the improvement effect of koi body color, and secondly, these two bait formulas added immune polysaccharides, brewer's yeast, kelp powder, and black rice flour. , purple sweet potato powder, chironomus larvae, escargot, squid, bacillus and many other additives, on the one hand, the formula is complex and increases the cost, making it unsuitable for large-scale koi breeding; on the other hand, it improves koi The effect of immunity is not obvious
