AI Technical Summary

Technical Problem

Existing koi feed lacks effective nutritional regulation methods to enhance the reflective brightness of iris cells, and fish scales, as a high-nutritional-value byproduct, are not fully utilized, resulting in insufficient brightness of the fish's body.

Method used

A specific feed combination, including fish meal, defatted Antarctic krill meal, soybean meal, peanut meal, spirulina powder, fish oil, and fish scale powder, is used. By adding Chinese toon polysaccharide and compound premix, feed pellets with a particle size of 1-3 mm are prepared. The guanine in the fish scale powder is used to enhance the reflectivity of the iris cells.

Benefits of technology

It significantly improves the metallic luster and overall brightness of koi carp, enhances their ornamental value, realizes the resource utilization of fish scales, reduces dependence on high-priced animal protein sources, ensures the safety and health of aquaculture, and enhances market competitiveness.
