Morphological Comparison of Cobitis elongatoides Bacescu et Maier, 1969 Populations (Pisces, Cobitidae) from Croatia

A comparison of Cobitis elongatoides Bacescu et Maier, 1969 populations (genus Cobitis) from Croatia was carried out on the basis of morphological analyses. The samples were collected by electro fishing during the period 2003-2005 in the Croatien rivers: Petrinjčica, Kupa, channel Kupa - Kupa and ilova (Sava river basin, Danube basin). Body pigmentation, the scale form as well as form and size of suborbital spine were determined. Thirty morphometric and eleven meristic characters were measured. The variance analysis (ANOVA) was carried out. Statisticly significant differences were established on the four characters (lac, H, laco, Ha). Scheffe - test was used for the post hoc analysis. Difference coefficient (CD) indicates that these four populations can not be considered a subspecies.
