Abstract

The invention discloses a composite feed attractant for fishing. The composite feed attractant is prepared from, by weight, 15-30 parts of glycine betaine, 2-6 parts of dimethyl betaine-beta-dimethylpropiothetin, 2-6 parts of disodium 5-inosinate, 20-30 parts of taurine, 30-50 parts of sleeve-fish ointment and fruit sugars and 10-20 parts of a fructooligosaccharide and bacillus licheniformis compound. The invention further discloses a preparation method and application of the composite feed attractant for fishing. Compared with the prior art, the composite feed attractant can obviously improve the ingestion amount, the weight gain rate and feed conversion ratio of fishes, crustaceans and terrapins and can remarkably strengthen the immune function and digestive enzyme activity of the intestinal tract and promote absorption and utilization of nutrient substances. In addition, the utilized raw materials are stable in source, low in price and simple in preparation process, and reduction of the production cost, decrease of feed waste and environmental protection are promoted.

Description

technical field [0001] The invention belongs to the field of feed additives, and in particular relates to a compound food attractant for fish and its preparation method and application. Background technique [0002] With the decline of fishery catches worldwide, aquaculture has become the main source of human demand for aquatic products. According to the statistics of the World Food and Oil Organization (2009), the amount of aquatic products supplied by aquaculture is growing at a rate of 9% per year. , which has become the fastest growing food industry. As an indispensable high-quality protein source in the fish feed industry, fishmeal is widely used in aquaculture because of its high protein content, good palatability, complete and balanced amino acid composition, and rich unknown growth-promoting factors. Skyrocketing prices due to low supply and rising demand, and environmental pressures from overexploitation of natural resources have forced the aquaculture industry to ...
