Morphological characters of Cobitis elongatoides (Cypriniformes ; Actinopterygii) in Croatia

The species Cobitis elongatoides Bacescu & Mair, 1969 is distributed through the rivers of the Danube basin. It has an exceptionally narrow ecological niche and its body is adapted for life in shallow waters with slow to no flow with a fine sediment substrate. The objective of this study was to obtain new information on the morphology of this species, and to determine whether there are morphological differences between populations in Croatia. The study examined populations in four rivers: Kupa, Petrinjcica, Sava and Drava. Morphological analyses included examining the morphometric and meristic traits and the external appearance. Populations from all four rivers were compared in the context of the available literature. The morphometric traits were analysed statistically and the obtained results compared with literature data.
