Embodiment 1

[0015] Take 30 parts by weight of betaine, 20 parts by weight of TMAO, 20 parts by weight of DMPT, and 30 parts by weight of allicin; pulverize the above-mentioned components through an ultrafine pulverizer, pass through a 120-mesh sieve, and fully mix them in a mixer to prepare Compound food attractant.

Embodiment 2

[0017] Growth test: Procambarus clarkii was provided by Lukou base of Jiangsu Freshwater Fisheries Research Institute. Shrimp that are healthy, of the same size and weight are selected for the test, and the initial average weight of each individual is about 4.31g. Randomly divided into groups, including control group A (feeding basal diet), control group B (adding 1.0% betaine to the basal diet), control group C (adding 1.0% TMAO to the basal diet), and control group D (add 1.0% DMPT to the basic diet), control group E (add 1.0% allicin to the basic diet), control group F (add 0.5% betaine + 0.5% allicin to the basic diet), control group G (add 0.5% TMAO+0.5% allicin to the basic diet), control group H (add 0.5% DMPT+0.5% allicin to the basic diet), control group I (add 0.2% betaine to the basic diet +0.2%TMAO+0.1%DMPT+0.5% allicin), the control group J (add 0.5% betaine+0.2%TMAO+0.2%DMPT+0.1% allicin in the basal diet) and the test group (in the basal diet 1.0% compound foo...

Embodiment 3

[0031] Take 35 parts by weight of betaine, 22 parts by weight of TMAO, 15 parts by weight of DMPT, and 28 parts by weight of allicin; pulverize the above-mentioned components through an ultrafine pulverizer, pass through a 120-mesh sieve, and fully mix them in a mixer to prepare Compound food 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...
