Abstract

The invention discloses a method for preparation of catfish feed. The catfish feed comprises white fish meal, green shrimp powder, pig liver powder, bean worm powder, animal protein powder, bitter gourd powder, hairtail powder, sorghum powder, vegetable protein powder, soybean meal, red sage root powder, safflower powder, malt powder, fennel powder and hawthorn powder according to weight percentages. The catfish feed has a low price, the ingredients are easy to acquire, the formula and the preparation method are simple, the feeding effect is good, and the cultured catfish grows fast and has a large volume, good physique and low morbidity. The catfish feed effectively solves the problem that the existing blended feed is short of nutrients and easily causes slow growth and development, a small volume, light weight, less vitality, poor palatability and a high morbidity rate of catfishes.

Description
