Length-weight and length-length relationships are presented for four freshwater fish species [Liza abu (Heckel, 1843), Aphanius mento (Heckel, 1843), Oxynoemacheilus hamwii (Krupp & Schneider, 1991) and Chondrostoma kinzelbachi Krupp, 1985] captured in Golba Lake, Hatay, Anatolia. No information regarding length-weight relationships was reported previously in FishBase for C.kinzelbachi, A.mento and O.hamwii. Specimens were obtained from January to May 2012 using electrofishing and cast nets. This study presents the first study on LWR data for C.kinzelbachi, A.mento and O.hamwii.
