The invention relates to the technical field of additives, and specifically discloses a composite preparation for fish feeding and a preparation method and application thereof. The composite preparation for fish feeding comprises the following raw materials: Bacillus psychrophilic and its fermentation metabolites, butyric acid , anti-stress agent, lysozyme, etc. The compound preparation for fish feeding is added to aquaculture water body or used to treat tap water for fish farming. When used to treat tap water, bleaching powder, nitrite and chlorine in tap water can be quickly treated; When breeding, it can enhance the intestinal function of fish, inhibit the growth of algae, quickly decompose feces, residual bait, and pigment, and solve the problems of narrow scope, weak targeting and easy pollution of existing additives for fish breeding; The provided preparation method is simple, the prepared composite preparation for fish feeding can increase the brightness of fish scales, make fish more colorful, reduce fish casualty rate, and has broad market prospects. |
