V originále

Diploid-polyploid complex of Carassius auratus is formed by several forms – C. gibelio, C. auratus, C. landsdorfi and M-line. The gibel carp (Carassius gibelio) belonging to C. auratus complex is one of the most common and successful non-indigenous invasive fish taxa in Europe. This C. auratus complex originates from East Asia (China). The different forms of C. auratus complex exhibit low level of morphometric and anatomical differences. In the Czech Republic, the representatives of C. auratus complex were firstly recorded in the area of the confluence of the rivers Morava and Dyje in 1976. Reproduction of this complex is ensured by asexual pathway using gynogenesis (in triploid females) and sexual pathway (in diploid specimens). In this study we investigate the potential aspects related to the evolution of diploid-polyploid C. auratus complex. The aim of this study was to evaluate the genetic diversity (mitochondrial DNA using D-loop region) of the C. auratus complex from the Dyje basin. The presence and intensity of infection for metazoan parasite species was compared between two different reproductive forms. The parameters of non-adaptive (i.e. respiratory burst, lysozyme activity and complement activity) and adaptive immunity (IgM antibodies) were compared between two forms in four consecutive years. Our analyses revealed no significant difference in parasite abundance between diploid and triploid specimens. Concerning the groups of parasites, only nematodes were significantly different in diploid females in comparison to triploid females and diploid males. On the other site, the highest infection values were found for D. dulkeiti and D. anchoratus for each of gynogenetic females, sexual females and sexual males. Results of this study showed that basic physiological and haematological parameters were affected by sex, only erythrocyte count was affected by ploidy status. No difference in non-specific immunity between two reproduction forms were reported.
