Abstract

An examination was made to find out whether the shape of the scales is suitable to discriminate gibel carp (Carassius gibelio BLOCH, 1782) populations. The tools of landmark-based geometric morphometrics were used. Fish were collected from four sampling areas. Three are connected with each other (Kis-Balaton Water Protection System stage I, Kis-Balaton Water Protection System stage II, Lake Balaton western basin), while one is separated from the others (Nagyberek, located on the Balaton-catchment). Two of the sampling areas (Kis-Balaton Water Protection System stage I, Kis-Balaton Water Protection System stage II) were hypertrophic, whilst the western basin of Lake Balaton and Nagyberek was mesotrophic. Carassius gibelio populations could be differentiated into three distinct groups based on their scale morphology, with good reliability (97.3%). Populations of the two stages of the Kis-Balaton Water Protection System could not be separated. Based on the linkage relationships and environmental parameters, the results suggest that the environmental and the possible genetic effects on scale morphology separated with this method. Although the genetic differences were not proved, only assumed.
