Some biological parameters of the bergamae barb, Capoeta bergamae Karaman, 1969 (Cyprinidae), in Kemer reservoir (Aydin, Turkey)

WOS: 000273126400002The 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 infinity:25.0 cm, K=0.344 year(-1) and t(0)=-0.93 year for males respectively L infinity:27.2 cm, K=0.308 year(-1) and to=-0.92 for females. Length-weight relationships were estimated as W=0.020*L(2.85) (R(2)=0.94) for males and W=0.021*L(2.84) (R(2)=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)
