Abstract

The comparison between two sexes of Iraqi freshwater fish Barbus luteus that was fished from Tigris
river at Baghdad during 2005, revealed that: the distance from head edge to the anal orifice & from head
edge to the dorsal fin were larger in males than females. Also, the females have dark colored fins with
reddish ventral aspect of head and body in comparison with the males during the whole months of study.
So, they were considered as permanently sexual dimorphism characteristics . But , during the spawning
season (May and June) a more brightening color of male with reddish coloration of both sides of body
were noticed in comparison with females with a golden orange corneal coloration in both sexes. Thus they
were considered as temporary sexual dimorphism characteristics.
