The invention provides a breeding method of temporarily-cultivating breeding of yellowtail amberjack fry. The method comprises the following steps: (1) building a cultivation pond: concretely buildinga cement breeding pond in a room, arranging a drainage opening of the cement breeding pond at the center of the bottom, enabling a water inlet to be inclined towards a pond wall, and arranging a plurality of aerated air stones in the cement breeding pond, so that the breeding pond is built; (2) preparing a fry temporary-cultivating breeding pond: concretely illuminating the breeding pond by usingnatural light, carrying out disinfection, and then injecting temporary-cultivating water; and (3) carrying out temporary-cultivating breeding: concretely disinfecting fry first, then carrying out fryscreening and pond division, carrying out breeding management on the fry by adopting a micro-flow breeding mode after the fry are stable, carrying out temporary-cultivating breeding until the lengthof the fry reaches 3 cm, and then feeding the fry into a net cage for carrying out adult fish breeding, wherein the breeding management comprises daily maintenance, water quality control and bait feeding. According to the breeding method disclosed by the invention, breeding cost of the yellowtail amberjack fry is reduced, and the fry obtained by the temporary-cultivating breeding is uniform in specification, fast in growth, high in adaptability and high in survival rate.
