Abstract

The invention discloses a preparation method for a fish feed. The preparation method comprises the following steps of (1) performing alkaline hydrolysis, namely, mixing peanut shells, wheat straws, soybean curd residues with plant ash, adding water for pulpifying, and stirring for reacting to obtain an alkaline hydrolysis product; (2) fermenting, namely, uniformly mixing corn, mulberry leaves, wheat bran and the alkaline hydrolysis product, adding amylase, protease, polysaccharase and cellulose, then adding yeast, and stirring and mixing uniformly for fermenting; (3) granulating, namely, drying a fermenting material, then, mixing mineral substances, bicarbonate and additives, and granulating in a granulating machine, wherein the particle size of the granulated particles is 0.5 to 1 cm; (4) coating, namely, coating the granulated fish feed particles in a fluidized bed, wherein the coating thickness is 0.05 to 0.1 cm; and (5) performing heat expansion, and placing the coated feed capsule particles for 2 to 4 hours at 40 to 60 DEG C. The preparation method for the fish feed provided by the invention is low in cost and simple in process; the obtained fish feed is low in settling velocity and rich in nutrition; and the pollution to a water body is avoided.

Description

technical field [0001] The invention relates to a method for preparing fish feed, which belongs to the technical field of agriculture. Background technique [0002] With the acceleration of urbanization and the pace of life, agricultural sightseeing and experience projects are becoming more and more popular. Through projects such as solar greenhouses, leisure fishing ponds, and agricultural sightseeing gardens, tourists can enjoy sightseeing while leisurely sightseeing. Labor experience, carry out field work such as fertilization, irrigation, weeding, picking, etc., enhance the farming cultural atmosphere of the sightseeing park, and enrich the fun of farm life for tourists. [0003] For children, feeding fish with fish feed can satisfy children's sense of accomplishment and let them experience the joy of labor. [0004] However, with the continuous input of fish feed, it will cause the eutrophication of the water body and cause the deterioration of the water body. Substan...
