Abstract: In this study some suggestions were made for the estimation of von Bertalanffy growth parameters in a better way. Parameters k ,L8 and t0 in the von Bertalanffy equation can be estimated by different methods. But most of these methods use mean length at age data. Using mean length at age data could create some errors in estimation of parameters. In order to avoid these errors, age should be corrected by using a correction factor. All corrected age and corresponding length were used in estimation by non-linear fitting approach. In this study growth parameters were estimated as L4= 37.494 cm, k=0.1491, t0=-1.384 by using the correction factors and non-linear fitting approach, and L4=37.37 cm, k=0.138, t0=-1.86 from Von Bertalanffy plot method for given example.
