The aim of this study is to provide initial data on some morphometric characters and condition factors of inland water crayfish, Astacus leptodactylus (Eschscholtz, 1823) from Kilickaya Reservoir in Turkey. The study was performed between August and October 2014. Differences of sex groups were also investigated. Sampled population was composed of 40% female and 60% male specimens. Results of the study can be summarized as follows; the mean carapace length 53.80±7.66 mm, mean carapace width 28.80±3.56, mean abdomen length 57.80±5.07 mm, mean abdomen width 20.60±2.07 mm, mean cheliped length 46.40±15.40 mm, mean cheliped width 17.80±4.60 mm, mean total length 111.60±12.07 mm, mean total weight 37.63±16.49 mm and mean condition factor 2.58±0.29 mm from Kilickaya Reservoir. The obtained predata results were compared with other studies from different aquatic habitats.
