Does host ploidy affect the parasitism level?
Original language description
On the model of tench (Tinca tinca, Cyprinidae), a fish species extensively bred in European aquaculture, we tested possible selective advantage in parasite resistance in triploids over diploids. During four sampling periods 81 diploids and 79 triploidswere collected from a breeding pond in Vodňany, Czech Republic. More than 12000 individuals of parasitic metazoans belonging to 13 species were recorded. Host sex did not affect either parasite abundance or parasite species richness. In concordance withour prediction, diploids tended to have higher parasite load than triploids throughout the year. Nevertheless, significantly higher overall parasite abundance in diploids compared to triploids was confirmed only in summer. Host ploidy appeared to be associated with the susceptibility or resistance to particular parasite species. Whilst diploid tench showed higher susceptibility to adult trematode Asymphylodora tincae, triploid tench was parasitized more by larval cestode Valipora camplyl
