The invention belongs to the bait research and exploitation technical field in fishery science. The invention relates to an optimum processing technology for a compound Chinese herbal medicine additive aquatic feed. By using different processing technology and component proportion on the compound Chinese herbal medicine, the compound Chinese herbal medicine can be taken as one of feed raw materials with low investment and high yield, the aquatic feed can effectively increase the feeding of the fish, absorption efficiency and assistant growth and the like, and can be taken as a novel feed resource for exploitation and application. The compound Chinese herbal medicine feed additive can be prepared by the following steps according to different processing technologies: inspecting medicines, weighting, using a water extraction or a crushing method, adding a formula feed, uniformly mixing, placing under the temperature of 30-38 DEG C for continuously fermenting for 1-2 hours to prepare the granular feed, and drying and moulding at the temperature of 60 DEG C. By culture tests, compared the test feed with the basic feed, the weight gain, specific growth rate, bait coefficient, feeding promotion activity equalization index of the tested fish can be tested, and the optimum processing technology and the component proportion can be determined. The research has important application meaning.
