Method for developing compound Chinese herbal medicine feed additive for procambarus clarkii

Abstract

The invention provides a method for developing a compound Chinese herbal medicine feed additive for procambarus clarkii, and relates to the technical field of aquaculture. The compound Chinese herbalmedicine feed additive comprises sweet wormwood herbs, radix scutellariae, radix isatidis, honeysuckle flowers, a mixed additive and feed raw materials. The method comprises the following steps of weighing the raw materials, mixing the sweet wormwood herbs with the radix scutellariae, the radix isatidis and the honeysuckle flowers, performing crushing, and performing screening so as to obtain thecompound Chinese herbal medicine feed additive; and adding the remaining mixed additive and the feed raw materials to the compound Chinese herbal medicine feed additive, performing mixing, and placingthe mixture in a puffing machine so as to obtain granules of which the particle diameter is 2.5 millimeters, so that the required feed is obtained. The feed made by the method disclosed by the invention has the advantages of being good in palatability, high in food calling properties, green, free from pollution and the like, the shelling speed of the procambarus clarkii is increased, the shellingmortality rate is reduced, and the weight increment rate and the specific growth rate of the procambarus clarkii are notably increased.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for developing a compound Chinese herbal medicine feed additive for Procambarus clarkii. Background technique [0002] Procambarus clarkii, also known as crayfish and red crayfish, originated in the southern United States and northern Mexico. Since it entered my country in the 1930s, with natural reproduction and artificial breeding, Procambarus clarkii has spread all over the Jiangnan waters of our country. . According to the data, the output of Procambarus clarkii reached 1.129 million tons in 2017, a year-on-year increase of 36.59%. It has become the number one freshwater aquaculture species in my country for two consecutive years, and Hubei, Anhui, Jiangsu, Jiangxi and Hunan have become the main crayfish in my country. Large farming province. According to statistics from the Catering Association, the annual consumption of Procambarus clarkii in Jiangsu Province a...

Problems solved by technology

[0003] At present, the aquaculture industry of Procambarus clarkii generally has problems such as low degree of intensification and backward aquaculture technology, and the occurrence of diseases in aquaculture is becoming more and more frequent (Ministry of Agriculture and Rural Affairs, 2018)

Chemical agents and antibiotics are commonly used in production to prevent and control the disease of Procambarus clarkii, but it is easy to cause negative effects such as environmental pollution and pathogenic organism resistance (Hao Chen et al., 2014)
