Abstract

Length-weight relationship and Fulton’s condition factor of Hemeri (Carasobarbus luteus) in Hoor Al-azim wetland (Khuzestan provinces, Iran) were investigated. During this study, from 2012 to 2013 more than 460 specimens' of C. lutus were measured. Mean±S.D length values for this species were 228±15 respectively and maximum and minimum total length were 118 and 362 mm respectively. Mean ±S.D weight values for this species were 190±91 g and maximum and minimum weight were 86 - 416 g respectively. The length-weight relation were calculated as W=0.0096 L3.11 (n=138,R2=0.97) for males, W=0.0079 L3.18 (n=271,R2= 0.94) for females, Y=0.0018L3.18 (n=466, R2 =0.96) for total fishes; verifying calculated b with 3 using Students t-test, there was no significant difference between calculated b and 3 (P>0.05) and the growth pattern was isometric. The b value in the length-weight relationship did not differ significantly between males and females (t-test, P>0.05). Fulton’s condition factor (K) for male and female and total fish was 1.38±0.12, 1.44±0.20, and 1.40±0.18 respectively and Students t-test showed no significant difference between Fulton’s condition factor of males and females (P>0.05). This study reports and provides basic information for fishery biologists in Iran.

Key words: Carasobarbus luteus, length-weight relationship, Fulton’s condition factor.
