Abstract

The invention discloses a preparation method of a shrimp and crab feed based on tea seed hulls, and belongs to the technical field of shrimp and crab culture. The shrimp and crab feed comprises the following raw material components in parts by mass: 10-16 parts of tea seed hulls, 15-25 parts of bean pulp, 10-15 parts of wheat bran, 5-15 parts of starch, 8-15 parts of fish meal, 2-6 parts of milk powder and 0.5-2 parts of table salt. The preparation method comprises the following steps: S1, performing weighing; S2, performing crushing: crushing tea seed hulls to obtain tea seed hull particles;S3, performing grinding: separately grinding the tea seed hull particles, bean pulp and wheat bran to obtain tea seed hull powder, bean pulp powder and wheat bran powder; and S4, performing granulating: performing blending extrusion on the tea seed hull powder, the bean pulp powder, the wheat bran powder, starch, fish meal, milk powder and table salt through a screw extrusion granulator to obtainthe shrimp and crab feed. The invention solves the problem that tea saponin in existing shrimp and crab feed needs to be extracted in an early stage and operation is complex.

Description

technical field [0001] The invention relates to the technical field of shrimp and crab cultivation, more specifically, it relates to a method for preparing shrimp and crab feed based on tea seed shells. Background technique [0002] Tea seed shell contains tea saponin, tea seed polysaccharide, tea seed protein and so on. Tea saponin is toxic to fish but not to shrimp. Tea saponin is highly toxic to fish, even when the concentration is very low, it is equally toxic, and its semi-lethal dose is 3.8mg / L. The salinity of water quality can promote the fish poisoning activity of tea saponin, and with the increase of water temperature, the fish poisoning activity of tea saponin also increases. Tea saponin is non-toxic to gill-breathing prawns. Shrimp and crabs need to molt during their growth process, and tea saponin can assist shrimp and crabs to molt and make them grow rapidly. It has the function of removing impurities such as aquatic animals. [0003] At present, many shrim...
