The invention relates to a foraging feed of a special compound feed for breeding stichopus japonicus and a preparation method of the foraging feed. The technical problems of poor disease control, high cost and the like in conventional breeding of the stichopus japonicus are solved. The foraging feed is prepared through the following steps of adding mixed microbe fluid to the following raw materials in parts by weight of 7-13 parts of soybean meal, 6-9 parts of sweet potato residues, 5-8 parts of corn steep liquor, 5-10 parts of sea mud, 3-5 parts of bran, 8-10 parts of soybean protein concentrate, 5-8 parts of yeast protein, 6-10 parts of wheat flour, 3-6 parts of shrimp powder, 3-5 parts of spirulina powder, 5-10 parts of sea spinach powder, 0.5-1.6 parts of sodium alginate, 0.5-1 part of bentonite, 4-8 parts of betaine, 0.5-4 parts of immune polysaccharide, 0.3-0.5 part of taurine, 0.5-2 parts of honeysuckle flowers, 1-3 parts of radix astragali, 0.5-1 part of gypsum, 0.8-2 parts of haws, 1-3 parts of licorice roots, 1-3 parts of activated carbon, 0.5-1.0 part of calcium propionate, 3-5 parts of complex vitamins, 0.5 part of complex enzymes and the like, and performing fermentation. The foraging feed is prepared through the following steps of mixing the raw materials, performing crushing, performing screening, performing fermentation, performing drying and the like. The foraging feed of the special compound feed is widely applied to breeding of the stichopus japonicus.
