The invention discloses a method for north-south hybridization and reproductive regulation breeding of Lateolabrax, which relates to the biotechnology breeding of Lateolabrax. The method comprises the following steps of: (1) taking a standby parent fish bred from the northern Lateolabrax seed as the male parent and a standby parent fish bred from the local wild Lateolabrax seed as the female parent; (2) breeding the male and the female parents to about 1500g to be used as the parent fishes; (3) artificially inducing the Lateolabrax through a reproductive regulation: controlling the time and the number of hatching of the Lateolabrax parent fishes by means of temperature, photoperiod and hormone injection, controlling the illumination time to 8h, reducing the temperature by 0.3 DEG C every day via a water cooler, and injecting CRH-A3 to the dorsal muscles of the parent fishes after anesthesia with allylguaiacol when the water temperature is reduced to 22 DEG C to induce the parent fishes to spawn, wherein the reproductive regulation induction period of the Lateolabrax is 7 days, and the Lateolabrax can be induced for several periods; (4) breeding the germ cells of the Lateolabrax; and (5) breeding juvenile fishes and breeding the juvenile fishes on a lower row when the sizes of the juvenile fishes reach more than 5cm. The invention has the advantage of breeding the new Lateolabrax seed which has the advantages of high temperature resistance, high growth speed, strong disease resistance and good quality by hybridizing northern and southern Lateolabraxes.
