Sažetak
The morphometric variation among several populations of Astacus astacus from different regions of 17 the Balkan Peninsula was studied based on a large set of morphometric parameters per crayfish. Differences in 18 morphometry among populations from ten water bodies in Serbia, Slovenia and Albania were tested using a 19 multiple discriminant analysis. Analyses included twenty-two morphometric parameters per crayfish. The most 20 discriminant characteristics for separating males among populations were weight, head width (HEW), width of 21 the carapace at the hind edges (CEW) and claw length (CLL), and for female populations those were abdomen 22 length (ABL), rostrum width (ROW), total length (TL), claw length (CLL) and claw width (CLW). Our results 23 improve the existing knowledge about the noble crayfish morphology, show clear differentiation between 24 populations from various aquatic ecosystems and reflect geographic separation.
