Chinese herbal medicine microecological preparation for Penaeus vannamei against transport stress and its preparation method and application

Abstract

The invention relates to a Chinese herbal medicine micro-ecological preparation for resisting transport stress in Penaeus vannamei, which is prepared from the following raw materials in parts by weight: 22-26 parts of gallnut, 14-21 parts of poplar flower, 5-20 parts of gentian, Cen 10-15 parts, Wujiapi 5-10 parts, fermentation strains and liquid culture medium. The preparation is obtained by fermenting the raw materials of Chinese herbal medicine in a liquid culture medium through fermentation strains. The beneficial effects of the present invention are as follows: 1. The raw material components of the compound Chinese herbal medicine have wide sources, low cost, simple preparation, and significant effects; 2. The fermentation strain is a beneficial bacterial strain capable of decomposing and producing antioxidant substances, and can release a large amount of active ingredients of the Chinese herbal medicine , and can improve shrimp disease control and intestinal health to a certain extent; 3. It can significantly reduce the stress red body phenomenon that occurs during the transportation of prawns; 4. It has obvious economic value when applied to Penaeus vannamei. The survival rate of transportation has been significantly improved.

Description

technical field [0001] The invention relates to an anti-stress compound Chinese herbal medicine microecological preparation, in particular to a Chinese herbal medicine microecological preparation for resisting transportation stress in Penaeus vannamei and its preparation method and application. Background technique [0002] Penaeus vannamei, also known as Litopenaeus vannamei, is commonly known as Penaeus vannamei. Compared with other cultured prawns in China, Penaeus vannamei has the advantages of fast growth, strong disease resistance, and wide adaptability to salinity. It is the highest yield of farmed shrimp in the world today. One of the three major species (Penaeus sinensis, Penaeus monodon, Penaeus vannamei). With the improvement of people's living standards, prawns are deeply loved by consumers because of their rich nutrition, soft meat, and easy digestion. [0003] In order to increase the output of prawn farming, the existing prawn farming adopts intensive farming...

AI Technical Summary

Problems solved by technology

[0005] In the process of high-density shrimp transportation, the stress loss caused by changes in the environment and other factors has also become a problem that cannot be ignored in the aquaculture industry. There is currently no biological agent for shrimp transportation stress on the market. Natural and non-polluting biological agents for white shrimp transportation are very important, which is of great significance for promoting the safety of shrimp transportation and improving the survival rate of shrimp transportation
