The present invention belongs to the field of aquaculture technology and discloses a compound anthelmintic granule for aquaculture, a preparation method, and an application thereof. The compound anthelmintic granule is prepared from raw materials such as emamectin benzoate, flubendiamide, a surfactant, an antioxidant, a disintegrant, and a filler. The present invention selects emamectin benzoate and flubendiamide as active ingredients to kill crustacean parasites. Currently, there is no oral anthelmintic compounded with these two ingredients as active ingredients for aquaculture. Emamectin benzoate paralyzes the parasites and is metabolized slowly in the body. It is highly toxic to aquatic animals and is not suitable for large-scale or long-term use. Flubendiamide's main mechanism of action is to inhibit chitin synthesis, and although it has a slow onset of action, it is relatively safe for aquatic animals and is particularly effective against parasites resistant to organophosphorus and pyrethroids. Clinical verification has shown that the two compounds synergize and are far more effective in killing crustacean parasites than existing aquatic insecticides.
