| description | Objective: In this study, some growth characteristics of Barbus cyclolepis Heckel, 1837 and Gobio bulgaricus Drensky, 1926 species living in Karasu Stream, were investigated. Materials and Methods: Sampling was carried out seasonal (August 2017, November 2017, January 2018, February 2018, April 2018) via electroshock. Samplings representing each season were repeated for 3 consecutive days. Lenght, weight, age, sex distributions and ratios, age-length, age-weight, length-weight relationships, Von Bertalanffy parameters, Fulton condition factor values of the obtained B. cyclolepis and G. bulgaricus individuals were analyzed. Results: The examined B.cyclolepis individuals are in the 0-III age groups. Standard length values are 3.5-13.5 cm; The weight values varied between 1.2232-50.8213 g. The female:male ratio was determined as 1: 0.94. In all individuals; Length-weight relationship was determined as W= 0.0253*SL2.9226. According to age, the lowest condition factor value was found in female individuals in the III age group (1.982), and the highest condition factor value was found in male individuals in the I age group (2.288). The age distribution of G. bulgaricus species varies between I-IV age groups. Standard length values are 2.5-9.6 cm; The weight values varied between 0.2989-18.3014 g. The female: male ratio was determined as 1:1.56. In all individuals; Length-weight relationship was determined as W= 0.0209* SL3.0081. According to age, the lowest condition factor value was found in male individuals in the II age group (1.950), and the highest condition factor value was found in female individuals in the IV age group (2.191). Conclusion: As a result of this study, some growth characteristics of Barbus cyclolepis and Gobio bulgaricus species living in Karasu stream were investigated for the first time. |
