Mart 1999- fiubat 2000 tarihleri aras›nda Bay›nd›r Baraj Gölünde Tinca tinca (L., 1758)’n›n büyüme özellikleri çal›fl›lm›flt›r. Toplam olarak 100 örnek (51 erkek ve 49 difli)’te inceleme yap›lm›flt›r. ‹ncelenen difli ve erkek bireyleri I-V yafllar› aras›nda da¤›l›m gösterdi¤i tespit edilmifltir. Efley oran› s›ras›yla erkeklerde % 51.0 diflilerde % 49.0 (1.04:1.0) olarak bulunmufltur. Çatal boy difli bireylerde 15.2-33.2 cm, a¤›rl›k 51.4-650.7 gr, erkek bireylerde 15.7-34.7 cm, a¤›rl›k 52.8-822.6 gr olarak bulunmufltur. Yaflboy ve yafl- a¤›rl›k iliflkisi Von Bertalanffy’e göre hesaplanm›flt›r. Ayr›ca, allometrik büyüme flekilleri boy- a¤›rl›k iliflkilerinden ortaya ç›kar›lm›flt›r. Y›ll›k oransal boy ve a¤›rl›k art›fl› ve yafl grubu için erkek, difli ve heriki efley için de hesaplanm›flt›r. T. tinca bireylerinin kondisyon faktorü, difliler için 1.57, erkekler için 1.55 ve tüm populasyon için 1.55 olarak bulunmufltur.

The growth features of tench, Tinca tinca, in Bayındır Dam Lake were studied between March 1999 and February 2000. A total of 100 samples (51 males and 49 females) were examined. Age in both sexes ranged from age group I to V. The sex ratio was 1.04 and 1.0 for males and females respectively. The fork length and weight of females and males varied from 15.2 to 33.2 cm and 51.4 to 650.7 g and 15.7 to 34.7 cm and 52.8 to 822.6 g respectively. Age-length and age-weight relationships were obtained using the Von Bertalanffy growth equation. Allometric growth patterns were obtained from the length-weight relationships. The condition factor was 1.57 for females, 1.53 for males and 1.55 for both combined. In addition, the relative annual increases in lenght and weight of T. tinca for males, females and both sexes combined were also determined.
