The age, growth and maturity of Capoeta bergamae Karaman, 1969, an endemic and vulnerable fish species from western Anatolia, were studied by monthly samplings throughout January - December 2006. Females represented 44.8% and males 55.2% of the individuals. Age determinations based on scale readings show that the population has four age classes. The von-Bertalanffy growth parameters were L∞:25.0 cm, K=0.344 year-1 and t0=-0.93 year for males respectively L∞:27.2 cm, K=0.308 year-1 and t0=-0.92 for females. Length-weight relationships were estimated as W=0.020*L2.85 (R2=0.94) for males and W=0.021*L2.84 (R2=0.97) for females. The growth characteristics of both sexes were allometric (b=2.85 males; b=2.84 females). According to gonadosomatic index values, the reproduction period began in May and continued til July. Males reached maturity at smaller lengths (FL: 14.0 cm [SD: 0.34], 1.9 years) than females (FL: 15.4 cm [SD: 0.39], 2.2 years). © NwjZ, Oradea, Romania, 2009.
