Remarks on Small-Scale Fisheries in the Lower Sakarya River (Turkey): Exploited Species and Catch Per Unit Effort (Cpue)

Abstract

Length-based estimations were evaluated in FiSAT II software. Total (Z), natural (M), fishing (Fcurr) mortality, exploitation rate (E curr) 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.
