Abstract :The relationship of age, growth and length-weight was analyzed for Chalcalburnus mossulensis from the Aşkale region of Karasu River from November 1995 to October 1997. Fish in the sample groups were between 1 and 7 years and the ratio of males to females was 1:1.08. Von Bertalanffy equations were used to find the growth in length for both sexes. The growth parameters for males and females were estimated to be L\infinity = 19.88869 cm, K = 0.1867795 and t0 = -2.3 and L\infinity = 21.8742 cm, K = 0.168014 and t0 = -2.1, respectively. We also found that the length-weight relationships were a = 0.0129 and b = 2.913 for males and a = 0.073 and b = 3.136 for femalesKeywords : Chalcalburnus mossulensis, age, growth, von Bertalanffy, length-weight relationship, Karasu River, Turkey
