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.
