Age and growth of Capoeta damascina (Valenciennes in cuvier and valenciennes 1842) in Daleki River of Boushehr province

In the present study, age and growth of (Capoeta damascina) in Daleki-Hele River in Boshehr province, the south part of Iran was studied. Five age classes, ranged from 0+ to 4+ years, were determined for males and females. The most frequent size classes belong to 11-13 cm and 15-17 cm for males and females, respectively. The length ranged from 72 to 224 mm and total weight ranged from 4.9 to 226 gr. Also, the condition factor ranged from 0.68 to 1.36. The females were dominant over males (1:1.55). Significant relationships were found between total length with weight for females (lnY=2.895 lnX-10.895, R2=0.965) and males (lnY=2.836 lnX-10.895, R2=0.959). The possible reasons for different age and growth condition of Capoeta damascina with other studied areas are discussed.
