本研究以3株不同地理位置的阿耳特米属植物（巴西1981年、中国天津1981年和美国旧金山湾1981年）为研究材料，分析了这3株阿耳特米属植物的化学成分，并考察了它们的nauplii对孵化场饲养的olivaceus白化病发生的影响。初始只饲喂轮虫的牙鲆孵化后9 ~ 10天（5.50±0.32mm TL）幼体，分别饲喂3种不同菌株中的一种与轮虫混合，直至牙鲆完成蜕变。比较巴西、天津和旧金山分别饲养BA、TA和SA三组比目鱼的白化率。白化病发生率以BA最高（99.5 ~ 100.0%），TA中等（81.3 ~ 84.6%），SA最低（21.1 ~ 26.1%）。种群密度、摄食水平等饲养条件与南澳基本相同。这些结果表明，叶蒿的某些化学成分与比目鱼白化的发生有密切的关系。然而，从3种不同菌株在矿物质、重金属、脂类、脂肪酸和残留农药等化学成分上的差异来看，并没有明确导致青蒿变色的主要因素。
Three geographically different strains of Artemia (Brazil 1981, Tien-tsin; China 1981 and San Francisco Bay; USA 1981) were used in this study, Chemical components of these 3 strains of Artemia were analyzed and the influences of their nauplii on occurrence of albinism in hatchery -reared Paralichthys olivaceus were examined. Larval flounder of 9-10 days post-hatching (5.50±0.32mm TL) which had been fed initially with only rotifers were given one of 3 different strains of Artemia nauplii mixed with rotifers until the flounder's completion of metamorphosis. Then the percentage occurrence of albinism was compared among 3 groups of flounder (BA, TA and SA) fed respectively on Artemia nauplii in Brazil, Tien-tsin and San Francisco. The percentage occurrence of albinism was highest (99.5-100.0%) in BA, intermediate (81.3-84.6%) in TA and lowest (21.1-26.1%) in SA. Population density, feeding level and the other rearing conditions in BA were almost the same as those in SA. These results suggest a close relationship between some chemical components of Artemia nauplii and the occurrence of albinism in flounder. However, principal factors in Artemia responsible for abnormal coloration were not specified from the difference of chemical components among these 3 different strains in terms of minerals, heavy metals, lipid class, fatty acids and residual pesticides.
