Length–Weight Relationships for Freshwater Fish Species in Küçük Menderes River Basin, Turkey

This study provides length–weight relationships for ten fish species from Küçük Menderes River Basin, inland water systems of Western Anatolian Region, Turkey. Samples were collected from six different localities, three reservoirs and three streams, in Küçük Menderes River Basin. The samples were collected using multimesh gillnets in reservoirs and electrofishing with ‘SAMUS 725-MP’ in rivers and fixed in formalin (4%). Identification of the fish species were done according to literature. Specimens of ten species belonging to three families were analyzed. The exponent b in the length-weight relationship ‘W=a(TL)b’ ranged from 2.54 to 3.52. The length-weight relationships for Barbus pergamonensis, Carassius carassius, Carassius gibelio, Chondrostoma holmwoodii, Cyprinus carpio, Gambusia affinis, Perca fluviatilis, Petroleuciscus smyrnaeus, Squalius kosswigi and Rhodeus amarus were given in this study. Information of length–weight relationships will be useful for researchers especially in conservation.
