The invention belongs to the nano-biotechnology and a nano-catalysis aquaponics method. The existing aquaponics technology has the disadvantages that the fish excrement decomposition speed is low, aquaponics starting time is long and production efficiency is low. The method includes the steps of preparing aquaponics nano-catalysts, smashing tourmaline, medical stone and zeolite till the density of meshes reaches 2500, accurately weighing purple grit mud, tourmaline, nanometer titania, nanometer magnesia, medical stone and zeolite, mixing all the compositions, pressing the mixture into a grain shape or a tablet shape with water content of 20%, sintering the mixture at a temperature of 1100 DEG C to 1200 DEG C for 10 hours, placing the nano-catalysts and aquaponics microbial strain bacillus into a fish breeding water body, pumping out fish breeding pool water to be used for vegetable planting, making water absorbed by vegetables flow back into the fish breeding water body, and repeating the circulating. The nano-catalysis aquaponics method has the advantages of being high in catalysis speed, quick in fish excrement decomposition, and capable of shortening the aquaponics starting time, saving resources and improving the aquaponics production efficiency.
