摘要
Perch (Perca (fluviatilis L.) caught in Lake Constance every 2 months over a period of 3 years below six towns or villages (Langenargen, Nonnenhorn, Rorschach, Romanshorn, Bottighofen, and the Lake of (Uberlingen) were examined for parasites. In contrast to Diplostomum spathaceum (Rudolphi, 1819) and Tylodelphys clavata (Nordmann, 1832), Bunodera luciopercae (Muller, 1776) and Ichthyocotylurus variegatus (Creplin, 1825) showed marked seasonal differences. These differences were influenced by various factors: the different numbers of the first intermediate hosts (snails, copepods), the water temperature, the physiological state of the fish, and its way of life.
