| Research Abstract |
Although flatfish juveniles are released into the sea all over Japan to enhance the flatfish resources, malformed juveniles of various types occurs at a high percentage when rearing. Individual growth history was examined to clarify the optimal growth rate to become normal juvenile. From the result on spotted halibut, it is recommended to enhance the growth to attain 8mm in total length by 18 days after hatching (before becoming flatfish shape). This is because the effect of thyroid hormone was different among individuals having different body size.
