    Seasonal dynamics of Posthodiplostomum cuticola (Digenea, Diplostomatidae) metacercariae and parasite-enhanced growth of juvenile host fish

  • Original language description

    The seasonal dynamics of Posthodiplostomum cuticola metacercariae in 0+ juvenile fish, Rutilus rutilus, Scardinius erythrophthalmus and Abramis bjoerkna, was studied on the floodplain of the Dyje River, Czech Republic. Prevalence and mean abundance of P.cuticola were significantly higher in R. rutilus than in S. erythrophthalmus or A. bjoerkna. A seasonal pattern of parasite infection with maximum values in autumn was evident in all three species. No effect of overwintering on the P. cuticola infectionwas detected. Parasite-induced growth was found for all three fish species investigated; the fish standard length and body weight of parasitized individuals were significantly higher than those of unparasitized fish from July to October. In April, no difference was found. The maximum enhanced growth of parasitized fish was found in months with low zooplankton densities, while the difference was lower when food was abundant.

    Sezónní dynamika metacerkárií Posthodiplostomum cuticola a jejich vliv na růst juvenilních ryb

  • Czech description

    Sezónní dynamika infekce metacerkariemi P. cuticola byla sledována u 0+ juvenilních ryb Rutilus rutilus, Scardinius erythrophthalmus a Abramis bjoerkna na lokalitách v záplavové oblasti řeky Dyje v České republice. Prevalence a průměrná abundance P. cuticola byla významně vyšší u plotice obecné než u perlína ostrobřichého nebo cejnka malého. Sezónní změny v infekci P. cuticola se projevily rychlým nárůstem prevalence i abundance v červnu a maximálním výskytem v říjnu. Průběh infekce neměl vliv na přežití první zimy. U všech tří druhů ryb byl pozorován intenzivnější růst parazitovaných jedinců, především při nedostatku potravy (nízkých hodnotách zooplanktonu).
