在实验室条件下，拟牙鲆幼鱼分别饲喂活蛹和配方饲料。在4种不同恒温（13、16、19和22•Ž）条件下，对4种不同大小的鱼进行4次饲养试验（9 ~ 10 d）。本研究使用的温度是根据若坂湾苗圃春季和初夏的温度选择的。在实验中，鱼被喂食活的蚕蛹或配方饲料。饵料饵料鱼的体长增长率均高于饲料饵料鱼（1.04 ~ 2.09倍）。体重（1.14-2.65倍）。3和4)，饲料效率更高（专家为1.56-4.34倍）。（3和4）在任何温度下都比用配方饲料喂养的要多。实验结束时鱼的化学成分（近似组成和脂肪酸谱）反映了饲料的化学成分，而活食饵鱼的化学成分与野生幼鱼的化学成分基本相同。
juvenile flounder Paralichthys olivaceus fed live mysids and formula feed under laboratory conditions. Four rearing experiments (9 to 10 days), using four different size fish, were conducted at four different constant temperatures (13, 16, 19, and 22•Ž). Temperatures used in the present study were chosen ac cording to those at the nursery ground in Wakasa Bay during spring and early summer. Fish were fed live mysids or formula feed during experiments. Fish fed live mysids showed always higher growth rates in length (1.04-2.09 times in expts. 1-4) and weight (1.14-2.65 times in expts. 3 and 4), better feed efficiency (1.56-4.34 times in expts. 3 and 4) than those fed formula feed at any temperatures. Chemical compositions (proximate composition and fatty acid profile) of fish at the end of experiments reflected those of diets, and those of fish fed live mysids were nearly the same as those of wild juveniles.
