Özet

The aim of this study was to determine the exploitation of 7 freshwater species, Freshwater bream (Abramis brama Linnaeus, 1758), Vimba bream (Vimba vimba Linnaeus, 1758), Wels catfish (Silurus glanis Linnaeus, 1758), Roach (Rutilus rutilus Linnaeus, 1758), European perch (Perca fluviatilis Linnaeus, 1758), Prussian carp (Carassius gibelio Bloch, 1782) and White bream (Blicca bjoerkna Linnaeus, 1758), from Lower Sakarya River, Turkey. Samplings were conducted from June 2017 to May 2018. Length-based estimations were evaluated in FiSAT II software. Total (Z), natural (M), fishing (Fcurr) mortality, exploitation rate (Ecurr) and CPUEs of all 7 species were determined. Results showed that almost all reference points stayed below the natural and fisheries mortality values. Besides overfishing, pollutants (chemical, physical and biological) and changes in the river morphology may affect the fish populations. Study results could be used for further fisheries management applications.
