The invention relates to a limanda aspera parent fish rearing and hatching method and belongs to the technical field of limanda aspera parent fish rearing and hatching methods. The limanda aspera artificial breeding and seedling raising method is characterized by mainly comprising the following steps: step1, parent fish source; step 2, parent fish rearing; step 3, artificial insemination; and step 4, fertilized ovum hatching. The limanda aspera parent fish rearing and hatching method has the advantages that by means of limanda aspera parent fish cultivating and egg-picking technology research, biology, ecology and physiology characteristics of limanda aspera offspring seed development can be mastered, and photo and temperature technical conditions for mature promotion of parent fish and effective accumulative temperature for egg laying can be found out; by researching the aspects such as water temperature, salinity, growth speed, fish bait utilization and conversion, offspring seed whitening rate reduction and disease control which are related to industrialized seedling production technique and process of limanda asperas, technological processes and operation regulations of limanda aspera offspring seed cultivating can be worked out; and limanda aspera cultivating operation regulations are worked out by researching growth rhythm and technical indexes such as released density, growth speed, fish bait feeding amount and water changing amount of limanda asperas in different periods under the condition of industrialized cultivating.
