Abstract: In this study age and growth features of tench (Tinca tinca L., 1758) living in Kapulukaya Dam Lake (Ankara, Turkey) were studied between April 2000 and March 2001. Totally, 150 tench were examined. Fish aged I-VII years were present and the population was 55.31% female and 44.69% male. The fork length and weight of females varied from 18.6-36.1 cm and from 85-1060 g, respectively and in males from 16.6-34.4 cm and from 140-1120 g, respectively. Age-length and age-weight relations were calculated according to von Bertalanffy growth equation formula. The following values were obtained for females and males, respectively. Lt = 45.11 [1-e(-0.15607 (t+1.97938)], Wt = 1974.62 [1-e(-0.1617 (t+1.8213)] 3.1752, Lt = 44.61 [1-e(-0.1617 (t+1.8213)], Wt = 1730.58 [1-e(-0.15607 (t+0.97938)] 2.9571. The length-weight correlation was found to be W = 0.0228 L2.9571 for males and W = 0.0111 L3.1752 for females.
