Length-weight relationships Carsobarbus luteus (Heckel 1843)

Length-weight relationships were estimated for Carasobarbus luteus wild population from the Karoon River, Aqilli desert discovered localities in the Iranian Tigris drainage. According to the monthly sampling for 1 year, 384 individual fish from Karoon River were collected. Standard length (SL), total length (TL) and fork length (FL) were measured by digital slide calipers and each body weight (BW) was taken by a digital balance. The sample size, length range, weight range, length weight relationships, 95 % confidence intervals of a and b, coefficient of correlation and growth type are given. Mean±S.D Standard length Values for Female and male were 170.19±25.38 and 154.24±19.30 respectively and maximum and minimum total length were 118 mm and 252 mm respectively. Isometric growth was identified from length-weight relationships. To the best our knowledge, this study presented the first reference on LWR for Carasobarbus luteus in Karoon River, Iran
