DISTRIBUTION METACERCARIAE PARACOENOGONIMUS OVATUS (TREMATODA, CYATHOCOTYLIDAE) IN THE MUSCLE TISSUE OF FRESHWATER FISH

Abstract

The distribution of metacercariae of trematodes Paracoenogonimus ovatus (Katsurada, 1914) in the muscle tissue of the population of freshwater fish, such as: roach (Rutilus rutilus), silver bream (Blicca bjoerkna), bream (Abramis brama), crucian (Carassius gibelio), rudd (Scardinius erythrophthalmus), pike (Esox lucius), pikeperch (Sander lucioperca). It is shown that the maximum number of metacercariae P. ovatus was localized in the dorsal muscles, namely near the dorsal fin and amounted to 41,3 % of the total number of identified parasites. The minimum number of indicators fluke metacercariae is observed in the anal fin – 2,1 %.
