In Bosnia and Herzegovina, noble crayfish (Astacus Astacus) can be found in the Sava River basin (rivers Bosna, Drina) and Adriatic basin (Cetina river) and it has been introduced in the Rama Lake and some accumulations in the Bosna River (Trozic- Borovac, 2011). The paper represents an overview of some morphological characteristics (W, TL, SL, CL, CW, CH), while condition indices were also calculated. The analysis of the noble crayfish was done in Prača River (Hrenovica site) in June and July 2009. The maximum-recorded length of the crayfish is 12.73 cm, and of 87 g (male) weight. We concluded that individuals vary mostly in body weight, and the least in body length. Out of the 30 analyzed specimens, males dominate (21:9) which results from the time/period of research. The values of condition index point to favorable conditions in Prača River for the existence of the species Astacus astacus.
