Compound preparation for promoting shedding and growth of shrimps and crabs and preparation method thereof

Abstract

The invention provides a compound preparation for promoting the shedding and growth of shrimps and crabs and a preparation method thereof. The compound preparation consists of 0.5 to 0.9 weight part of molting hormone, 40 to 60 weight parts of oriental waterplantain rhizome, 65 to 85 weight parts of gentian, 70 to 80 weight parts of common selfheal fruit-spike, 20 to 30 weight parts of glucan and 20 to 30 weight parts of zeolite. The preparation method comprises: weighing the molting hormone, the oriental waterplantain rhizome, the gentian, the common selfheal fruit-spike, the glucan and the zeolite, which serve as raw materials, in weight part; and uniformly stirring the raw materials to obtain the compound preparation. Through the synergy of the component, the compound preparation for promoting the shedding and growth of shrimps and crabs can promote the metabolism and in-vivo protein synthesis of shrimps and crabs to allow shrimps and crabs to shed in time and can improve the immunity and digestion of shrimps and crabs, promote growth and improve survival rate; and the preparation method is simple and meets the needs for large-scale industrial production.

Description

Technical field [0001] The invention relates to a compound preparation and a preparation method thereof, in particular to a compound preparation for dehulling shrimps and crabs to promote growth and a preparation method thereof. Background technique [0002] In the process of shrimp and crab breeding, due to the influence of various factors such as water quality, external environment, and incomplete nutrient species in the bait, it is difficult to shell shrimp and crab, which seriously affects the normal growth of shrimp and crab, making the cultured shrimp, The individual crabs are smaller than their counterparts living in the natural environment, even leading to a reduction in the survival rate of aquaculture. Therefore, the development of a preparation that can smoothly shell shrimps and crabs is of great production and practical significance. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a compound preparation for d...

Problems solved by technology

[0002] During the breeding process of shrimps and crabs, due to the influence of various factors such as water quality, external environment, and incomplete nutritional varieties in the bait, it is difficult to shell shrimps and crabs, which seriously affects the normal growth of shrimps and crabs, making the cultured shrimps, crabs, etc. Individual crabs are smaller than their counterparts living in the natural environment, which even leads to a decrease in the survival rate of breeding. Therefore, it is of great practical significance to develop a preparation that can successfully shell shrimp and crabs.
