Penaeus vannamei phagostimulant as well as preparation method and use method thereof

Abstract

The invention belongs to the technical field of aquaculture, and particularly relates to a penaeus vannamei phagostimulant as well as a preparation method and a use method thereof. The phagostimulantis prepared from the following components in percentage by mass: 35 to 45% of Chinese herbal medicine extracts, 15 to 25% of animal extracts, 20 to 30% of compound amino acids, 5 to 10% of allicin and5 to 10% of vitamin C. According to the invention, a plurality of Chinese herbal medicine extracts, animal extracts, compound amino acids, allicin and vitamin C are compounded and mixed according toa certain ratio; the prepared phagostimulant can stimulate smell, taste, vision and the like of penaeus vannamei; the penaeus vannamei phagostimulant can attract penaeus vannamei to the periphery of feed, improve appetite, accelerate food intake, improve feed intake and feed utilization rate, reduce dissolution loss waste of feed in water, and reduce pollution of residual feed decay to water quality, so that the growth rate of penaeus vannamei is improved, and the compound amino acids, allicin and vitamin C can also promote penaeus vannamei resistance improvement and reduce diseases.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a food attractant for Penaeus vannamei and a preparation and use method thereof. Background technique [0002] Penaeus vannamei, also known as Litopenaeus vannamei, belongs to Arthropoda, Crustacea, Decapoda, Natantia, Penaeidae, Penaeus, Litopenaeus The subgenus is native to the Pacific Ocean coastal waters from northern Peru to Sanora, Mexico, and was introduced into my country for breeding in 1988. Due to its rapid growth, strong stress resistance, high nutritional value, high-density and low-salinity farming and other advantages, it quickly became the absolute dominant species of prawns in my country after being introduced. [0003] With the rapid development of high-density intensive culture of Penaeus vannamei, a series of problems such as weakened physique, slow growth, and increased disease seriously restrict the healthy and sustainable development of Pena...

AI Technical Summary

Problems solved by technology

[0003] With the rapid development of high-density intensive culture of Penaeus vannamei, a series of problems such as weakened physique, slow growth, and increased disease seriously restrict the healthy and sustainable development of Penaeus vannamei culture. It is very important in shrimp farming. During the production and storage of conventional compound feed, it will more or less lose its original color and flavor, and even have a special odor, resulting in poor breeding effect and palatability, and the feeding rate of shrimp. The utilization rate of feed and feed is low, which is not conducive to the healthy growth of prawns, and the residual bait and feces will lead to the deterioration of the breeding environment, resulting in the growth of harmful bacteria, and eventually lead to the outbreak of large-scale shrimp diseases
