| Golden barb, Carasobarbus luteus (Heckel, 1843), belongs to the Barbus genus and is one of the freshwater species of Iran and native to Shadegan wetland. Some biological characteristics of Carasobarbus luteus were studied in Shadegan Wetland. Monthly samples were collected from five stations; Doragh (Mahshahr), Rogabe, Khorosy, Salmane and Atish from April 2013 to Mars 2014. 1608 specimens (276 males and 1332 females) were collected and measured. Results showed Mean±s.d length values for the male and female were calculated as 161±28(110-222), 174±38(95-280) mm respectively and mean±s.d weight values were 60±31(15-175), 80±39(15-370)g respectively. The length-weight relation were calculated as W=0.00003L2.83 (R2=0.84) for males, and W=0.0001L2.80 (R2= 0.86) for female; that determined negative allometeric model. The mean values of condition factor (K) were 1.77± 0.14 in males and 0.78± 0.27 for females and have no significant different (P>0.05). The spawning peak was determined in April, and length at maturity (LM), consume per biomass (Q/B) and production per biomass (P/B) were calculated for males and females as below LM=152, 139 mm; P/B= 0.71, 0.52 and Q/B=15.41, 12.37 respectively. |
