The aim of study is to determine the length-weight relationships, condition factors and total length in frequency distributions of five species of the genus Barbus. Specimens were collected from 24 locations, including one lentic system (Küçükler Reservoir) and 23 lotic systems (Büyük Menderes, Gediz, Sakarya, Susurluk, Dalaman Rivers and their tributaries; Esen, Tersakan, Yuvarlakçay, Kargi, Zeytinli, Tuzla and Gönen streams) in the western Anatolia. Fish samples were collected in June 2010, April-July 2019 and June-July 2020. Length-weight relationships, condition factors and total length in frequency distributions were estimated for five Barbus spp. (Barbus xanthos, B. pergamonensis, B. oligolepis, B. niluferensis and B. escherichii). Computed exponent b, R2 and condition factor values ranged from 2.4495 to 3.3881, 0.9027 to 0.9966 and 0.94 to 1.52, respectively. New maximum lengths are provided for two species: Susurluk River-Simav Stream, B. oligolepis, 329.75 mm and Susurluk River-Nilüfer Stream, B. niluferensis, 173.81 mm. New maximum weights are provided for two species: Esen Stream, B. xanthos, 196.58 g and Gediz River, B. pergamonensis, 95.07 g. The present study includes first records of LWRs parameters for two endemic species (B. xanthos and B. pergamonensis) in western Anatolia.
