[0005] The Chinese invention patent of CN 103598443 B discloses a catfish feed. The inventive method is to mix corn, soybean dregs, soybean meal, corn stalks, black soybean powder, secondary powder, waterworm powder, sheep liver powder, shrimp shell powder, seaweed powder, Dry yeast, dehydrated clover powder, lettuce, salt, and food attractant are mixed to make 0.5-1.0mm crumbs, which have the characteristics of rich nutrition and strong palatability, but the inventive method is only corn, soybean dregs, soybean meal, and corn stalks. The main ingredients such as black soybean powder and so on are simply mixed without fermenting and decomposing them. The anti-nutritional substances in these main ingredients will inhibit the absorption and utilization of nutrients by catfish. At the same time, this feed is not conducive to the consumption of juvenile catfish
