Dactylogyrus communities in Barbus meridionalis and B. barbus from hybrid zone in southern France
Original language description
During the period 2007-2012, we performed sampling of different Barbus populations in the southern France. Fish were identified using 30 microsatellite loci. Of all 243 studied individuals, we detected only 17 hybrid specimens in four fish populations. Lower values of expected heterozygosity were found in the allopatric populations of B. meridionalis compared to the pure populations of B. barbus. However, there were no significant differences in genetic variability between populations of both species. According to the published data, Dactylogyrus carpathicus and D. dyki parasitize both Barbus species investigated, but D. malleus is specific for B. barbus. Our fish examination for the presence of metazoan parasites revealed that D. malleus and D. carpathicus were the most abundant and prevalent in allopatric populations of B. barbus. D. dyki in low abundance was present solely in allopatric B. meridionalis populations.
