The invention discloses a puffing particle compound feed for intermediately adult sturgeons, which is suitable for feeding sturgeons at an intermediately adult stage, i.e. intermediately adult sturgeons with the weight higher than 600g. The compound feed is a mixture prepared from the following components in percentage by weight in a puffing particle feed processing method: 30%-40% of fish meal, 18%-20% of flour; 10%-15% of soybean meal, 10%-15% of peanut meal, 6%-9% of fish oil, 2%-6% of beer yeast, 1%-3% of soybean lecithin oil, 1%-3% of minerals, 0.2%-0.5% of choline chloride, 1%-2% of monocalcium phosphate and 0.2% of fishing multi-vitamin. The invention has the advantages that compared with other compound feeds, the puffing particle compound feed for intermediately adult sturgeons has low cost, good predatory lure, good stability in water, good economic benefits and a good breeding effect, and the intermediately adult sturgeons grow quickly.
