DACTYLOGYRUS PARASITES (MONOGENEA) IN COMMON BREAM (ABRAMIS BRAMA) AND ROACH (RUTILUS RUTILUS) (CYPRINIDAE) AND THEIR RESPECTIVE HYBRIDS
Popis výsledku v původním jazyce
Hybridization is very common process in fish which help them to adapt for environmental changes and parasite pressure. This study was focused on the analyses of parasite infection (i.e. the intensity of infection of the dominant parasite group ? Dactylogyrus species) in two cyprinid species living in sympatry, common bream (Abramis brama) and roach (Rutilus rutilus), and their respective hybrids collected from Hamry reservoir (Czech Republic). The fish were sampled in spring and autumn 2011. The difference in seasonal occurrence of Dactylogyrus species was analyzed. Total Dactylogyrus abundance was higher in parental species when compared to Dactylogyrus abundance in hybrid specimens. Roach was parasitized by 8 Dactylogyrus species and common bream wasparasitized by 3 Dactylogysrus speices. Hybrids harbour all Dactylogyrus species of roach but only one Dactylogyrus species (D. auriculatus) parasitizing common bream.
