An efficient cultivation method of a turbot family offspring comprises the following steps: parent fish selection, parent fish cultivation, artificial directional mating, hatching, offspring cultivation and getting of commercial offsprings. The parent fish is selected from germplasm parent fish of different batches from different countries; artificial fertilization is performed among different germplasm parent fish, and the same batch of the parent fish are not allowed to mate with each other; offspring cultivation is as follows: at the early period, the adopted facility is a 3m<3> glass reinforced plastics barrel, and bait comprises chlorella, rotifer and artemia; at the middle period, the adopted facility is a 10m<3> cement pond, and the bait is micro pellet bait; at the later period, the adopted facility is a 20-30m<3> cement pond, and the bait is fish larvae pellet bait; and specification of the commercial offsprings is 5-6cm. The method is characterized by adopting the parent fish with different germplasm resources for the artificial directional mating, and seriously controlling inbreeding; and adopting different culturing facilities to cultivate the offspring by three stages, which causes the offspring emergence rate of the commercial offspring to reach 46.8%, and improves growth rate thereof by 36%, and lowers of etiolation rate thereof below 5%. The method can efficiently produce high-quality turbot offsprings, and is applicable to large-scale production.
