Abstract

Abstract Morphological asymmetry was analysed in two marine fish species Acanthopagrus arabicus and Planiliza klunzingeri, in brackish and freshwater habitats in southern Iraq. For both species, specimens from the Shatt al-Arab River and Shatt al-Basrah Canal exhibited greater asymmetry values for snout length. In both locations examined, the levels of asymmetry of the physical traits increased as the fish grew. The high levels of asymmetry in the two fish species may be linked to heavy metal pollutants in the two aquatic environments studied.

从伊拉克南部的半咸水和淡水环境中采集的两种海水鱼类阿氏棘背鱼（Sparidae）和克氏扁背鱼（Mugilide）的形态不对称性

摘要分析了伊拉克南部咸淡水和淡水生境中棘鱼(Acanthopagrus arabicus)和Planiliza klunzingeri两种海鱼形态的不对称性。对于这两个物种，阿拉伯河和巴士拉运河的标本在鼻部长度上表现出更大的不对称值。在这两个被调查的地方，身体特征的不对称程度随着鱼的生长而增加。这两种鱼类的高度不对称可能与所研究的两种水生环境中的重金属污染物有关。
