Morphology, Age and Growth of Bunni, Barbus sharpeyi Gunther, 1874 in Swab marsh, south Iraq

Morphology, age and growth of Bunni, Barbus sharpeyi Gunther, 1874 in Swab marsh, south Iraq, was studied from December 2004 to November 2005. A total 864 B. (100-533mm TL) were collected using gill nets different mesh sizes electrical fishing. Twenty one morphometric seven meristic characters for the species described study. The calculated as numerical ratio standard head lengths. indices associated with length ranged 0.0043 eye diameter 1.22 length, 0.178 0.752 width. slopes regression lines 0.023 1.142 length. Fishes 200-360mm groups dominants samples.
