Abstract :In this study, a total of 1283 samples of five fish species belonging to two families, Cyprinidae and Leuciscidae, were collected from the Lower Sakarya River between June 2017 and May 2018 in order to determine some growth parameters.The samples were collected monthly with trammel net, fykenets, and electro shocker. The age of the fish was determined from the scales. The von Bertalanffy`s growth model was calculated Lt = 92.18insert ignore into journalissuearticles values(1-e-0.054insert ignore into journalissuearticles values(t+0.040);); for A. brama, Lt = 69.40insert ignore into journalissuearticles values(1-e-0.040insert ignore into journalissuearticles values(t+0.030);); for B. bjoerkna, Lt = 51.09insert ignore into journalissuearticles values(1-e-0.114insert ignore into journalissuearticles values(t+0.024);); for C. gibelio, Lt = 48.11insert ignore into journalissuearticles values(1-e-0.088insert ignore into journalissuearticles values(t+0.023);); for R. rutilus and Lt = 41.74insert ignore into journalissuearticles values(1-e-0.104insert ignore into journalissuearticles values(t+0.035);); for V. vimba. The phi-prime growth performance index insert ignore into journalissuearticles values(Φ`); value was computed as 2.628, 2.268, 2.474, 2.307 and 2.260 for A. brama, B. bjoerkna, C. gibelio, R. rutilus and V. vimba, respectively. This study provides basic information on some growth parameters of five fish species living in the Lower Sakarya River. The results of this study are useful for fishery managements and stock assessment in the Sakarya River.
