Abstract

The invention relates to a fish feed and a preparation method thereof, in particular to a grouper compound feed and a preparation method thereof. The grouper compound feed consists of the following raw materials in percentage by mass: 30 to 40 percent of fish meal, 15 to 20 percent of bean pulp, 10 to 20 percent of wheat high protein flour, 20 to 30 percent of flour, 1 to 2 percent of yeast powder, 1 to 2 percent of compound vitamin, 0.1 to 1 percent of compound mineral matter, 0.5 to 1 percent of choline, 1 to 2 percent of monocalcium phosphate, 2 to 4 percent of isinglass, 0.1 to 0.5 percent of VC and 1 to 2 percent of dried small shrimp powder. The feed of the invention is prepared by refining according to the growth characteristic and nutritional requirement of the groupers, has comprehensive nutrition and strong food calling property, can furthest release the growth potential of the groupers, adds various mineral matters and vitamins and can improve the gut immunologic barrier and strengthen the immunologic function.

Description

【Technical field】 [0001] The invention relates to a fish feed and a preparation method thereof, in particular to a grouper compound feed and a preparation method thereof. 【Background technique】 [0002] Grouper (Epinephelus spp), also known as piebald and grouper, belongs to the genus Grouper of Fataceae. There are more than 100 species, which are distributed in the Red Sea, the Indian Ocean and the western Pacific Ocean. Our country is produced in the South China Sea and the East China Sea. It is a carnivorous and bottom-dwelling fish. It grows fast, has large individuals, rich nutrition, and delicious meat. People love it, and it is an excellent variety for sea farming. In recent years, my country has also carried out research on artificial propagation and cage culture technology. In order to reduce costs, improve economic benefits, and ensure sufficient feed supply, research has been carried out on its nutritional needs, but no good results have been achieved. There are...
