Mean length-weight relationship and condition factor of some Cyprinid fishes in Göynük Stream, Murat River of Eastern Türkiye, Bingöl

The Length-weight relationships (LWRs) are very important to data for accurate estimate of populations in stock menagement. In this study, the length-weight some fish Göynük stream, Murat River (Bingöl/Turkey) were examined. LWRs and condition factor (K) Cyprinon macrostomus, Gara rufa, Barbus lacerta, Acanthobrama marmid analyzed. was estimated using linear regression model. obtained as TW = 0.013L2.98, 0.057L2.40, 0.016L2.79 0.029L2.82 C. G. B. lacerta A.marmid, respectively. b values acquired four species ranged from 2.13 (G. rufa-Male) 3.34 (B. lacerta-Male). K varied 0.90 (A. marmid-Male) 1.27 rufa-All), indicating that most good condition. However, macrostomus rufa better than A. marmid. study has provided baseline information on LWR Stream. datas would be useful adapt adequate regulations sustainable estimation stream fishery biologist.
