In this study, the age, growth and reproduction properties of 627 barbels, Barbus plebejus escherichi (Steindachner, 1897), from Oltu Stream in the Çoruh River Basin were investigated during a period from August 1994 to July 1996. The age of this species ranged between age groups 1 and 10, the second age group being dominant. Individuals were composed of 64.59% males and 35.41% females. von Bertalanffy growth parameters and length-weight relationships were Lt=29.35x(1-e-0.139(t+1.640)), Wt=281.11x(1-e-0.139(t+1.640))2.843 W=0.0189.FL2.843 (r=0.96) in males and Lt=32.77x(1-e-0.116(t+1.891)), Wt=392.10x(1-e-0.116(t+1.891))2.911, W=0.0152.FL2.911 (r=0.97) in females. Condition coefficients of males and females were calculated to be 1.221 and 1.220 respectively. Sexual maturity was 11.45-13.75 cm fork length (2-3 years old) in males and 13.65-15.95 cm (3-4 years old) in females. Fecundity was calculated to be 1256 (3rd age group)-8445 (7th age group) eggs/female. The spawning period was between May and July when the water temperature was between 14 and 19ºC in both years.
