研究了巴西卤虫无节幼体的摄食期对牙鲆幼鱼出现白化的影响。最初用褶皱臂尾轮虫饲养牙鲨幼体至5.57 mm TL。卤虫无节幼体在4个不同的摄食期(5.57 mm至16.1-18.7 mm TL(完全变态))投喂给卤虫幼体。轮虫也被用于饮食。根据白化部分，对16.1~18.7mmTl的牙鲆幼鱼白化病进行了分类。从早期(5.57 mm和8.67-8.86 mm TL)开始摄食卤虫，白化发生率特别高，出现率为97.0-97.6%，白化部位几乎遍及眼侧。从后期(10.21-10.43 mm和12.98-13.23 mm TL)取食卤虫可减少白化病的摄食量(分别为83.5-82.9%和22.9-24.1%)，并限制在相当有限的眼侧。这些结果表明，仔鱼白化病的发生与仔鱼阶段摄食特定的食物有密切关系。
The influence of feeding periods of Brazilian Artemia salina nauplii on the appearance of albinism in juvenile flounder P. olivaceus was examined. Flounder larvae were initially reared with only rotifer Brachionus plicatilis to 5.57mm TL. Artemia salina nauplii were given to floun-der larvae on four different feeding periods from 5.57mm to about 16.1-18.7mm TL (complete metamorphosis). Rotifer was also used for the diet. Albinism on juvenile flounder (16.1-18.7mm TL) were classified based on their albinic portions. Feeding with Artemia from the earlier stages (5.57mm and 8.67-8.86mm TL) resulted in the especially high frequency occurrences of albinism 97.0-97.6%, and the albinic portions extended over almost all of the ocular side. Feeding with Artemia from later stages (10.21-10.43mm and 12.98-13.23mm TL) reduced those of albinism (83.5-82.9% and 22.9-24.1% respectively), and their ablinic portions restricted to rather limited part of ocular side. These results suggested the close relationship between albinism oc-currence of juvenile flounder and giving a particular kind of food during larval stage.
