The invention relates to a technology for breeding grouper fries. The technology specifically comprises the following steps: (1) setting breeding conditions: breeding the fries by commonly using a glass fiber reinforced plastic water tank, a cement pond or a net cage, wherein the container has the volume of 5 cubic meters to 50 cubic meters and the water depth of 1 meter to 2 meters, is circular or rectangular and is kept out of direct sunning, and the intensity of illumination is controlled to be 20,000lx to 30,000lx or below by window shades; (2) preparing appropriate feedstuff: feeding S-shaped rotifers at the density of 10 rotifers per milliliter several hours before the mouth opening of larva fishes, wherein during the feeding of animal plankton, a green water technology should be adopted, and single-celled algae is added into water; and (3) carrying out daily management: adopting still-water slightly-aerated breeding at the first 7 to 10 days of primary-stage breeding, wherein during still-water breedin
