Abstract :This study was conducted using 201 Barbus lorteti insert ignore into journalissuearticles values(Sauvage, 1882); individuals, obtained in 1997 from Asi River. In this study, the length-weight and age-weight parameters were estimated using the von Bertalanffy growth equation. The total length for the individuals was varied between 7.4 and 31.0 cm with an average of 18.37 cm. The distribution of weight was fixed as 3.8 and 274.9 g and 82.57±4.3 g in average. The length-weight relationship was estimated as W= 0.013*L 2.97 . In the age based scale readings-of the individuals in the sampling the age classes were ranging between I-IV. For this species, von Bertalanffy equation in length growth were estimated as L t =28.45 [1–e -0.43insert ignore into journalissuearticles values(t+insert ignore into journalissuearticles values(-0.23);); ], and the equation in weight growth was estimated as W t = 382.76*[1–e -0.34insert ignore into journalissuearticles values(t+insert ignore into journalissuearticles values(-0.19); ] 2.97 . The growth performance index insert ignore into journalissuearticles values(Φ); and Condition factor was estimated as 2.56 and 1.11, respectively.
