Xanthism, an abnormal skin colouration of yellow to orange-gold, is an uncommon phenomenon in nature and xanthochromic specimens are rare. We report and describe four incidences of adult xanthochromic specimens observed in Scomberomorus commerson, Lobotes surinamensis, Sphyraena putnamae and Seriola rivoliana collected from the Arabian Sea coasts of Pakistan. The specimens of S. commerson, S. putnamae and S. rivoliana displayed an overall loss of dark pigmentations, while the two specimens of Lobotes surinamensis retained some patches of dark pigmentations on their bodies. This appears to be the first documented record of xanthochromism in the families Scombridae, Lobotidae and Sphyraenidae from in the Arabian Sea.

黄化是一种从黄色到橙金色的异常皮肤着色，在自然界中是一种不常见的现象，而黄变标本很少见。我们报告并描述了从巴基斯坦阿拉伯海沿岸收集的Scomberomorus commerson、Lobotes surinamensis、Sphyraena putnamae和Seriola rivoliana 中观察到的四种成年黄变标本。S. commerson、S. putnamae 和 S. rivoliana的标本显示出整体深色色素沉着消失，而Lobotes surinamensis的两个标本在他们的身体上保留了一些深色色素沉着。这似乎是阿拉伯海 Scombridae、Lobotidae 和 Sphyraenidae 科黄变的第一个记录。
