Feeding attractant for juvenile procambarus clarkii as well as preparation method and application of feeding attractant

Abstract

The invention discloses a feeding attractant for juvenile procambarus clarkii as well as a preparation method and application of the feed attractant. The feeding attractant comprises the following components in parts by weight: 30-40 parts of lycine, 15-25 parts of kanirin, 15-20 parts of dimethyl-beta-propiothetin and 20-30 of allicin. The preparation method of the feeding attractant comprises the following steps: weighing the components according to the weight parts and then mixing uniformly. The raw materials of the feeding attractant is stable in source and can be taken from a wide range, the production process is simple, the cost is low, and the effect is obvious; from the food intake and digestion mechanism of crustacean, the feeding attractant improves the food intake rate of procambarus clarkia bodies and reduces the waste of baits, simultaneously, the activity of digestive enzymes of the intestines and pancreases of the juvenile procambarus clarkii is improved to promote the growth of the procambarus clarkii.

Description

technical field [0001] The invention belongs to the field of aquaculture, and relates to a food attractant for juvenile Procambarus clarkii and its preparation method and application. Background technique [0002] Procambarus clarkii (Procambarus clarkii), commonly known as "crayfish", belongs to the phylum Arthropoda and the class Crustacea. It is the most important species of freshwater crawfish in the world today, and its output accounts for 70%-80% of the total crayfish production. Since it was introduced into my country in 1981, it has been favored by consumers because of its delicious meat and rich nutrition. It has been widely distributed in Jiangsu, Anhui, Hubei, Zhejiang and Shanghai, and has become an important economic aquaculture target in my country. With the continuous expansion of the scale of farming and the improvement of the degree of intensification, the demand for artificial feed for Procambarus clarkii, especially in the juvenile period, continues to exp...

AI Technical Summary

Problems solved by technology

However, many food attractants currently on the market have disadvantages such as high cost, poor stability, low food attractant effect, general nutritional level, and poor pertinence. Therefore, the development of targeted, effective and low-cost food attractants has become a research hotspot. ,

[0004] At present, there are some reports about the small amount of use of betaine, trimethylamine oxide (TMAO), dimethyl-β-thiatin propionate (DMPT) and allicin in aquaculture, but the relationship between these Compatible use, has not been reported yet
