Parastic fauna of Arctic charr, Salvelinus alpinus (L., l758) from the Hornsund region (Spitsbergen)

Parasites found in 64 individuals of Salvelinus alpinus were identified. A total of 5 parasitic species belonging to 3 higher tax were found. Plerocercoids of Diphyllobothrium sp. cestodes occurred between the peritoneal membrane and ventral muscles as well as in the stomach walls. Individuals of th...

Description
Summary:Parasites found in 64 individuals of Salvelinus alpinus were identified. A total of 5 parasitic species belonging to 3 higher tax were found. Plerocercoids of Diphyllobothrium sp. cestodes occurred between the peritoneal membrane and ventral muscles as well as in the stomach walls. Individuals of the cestode Eubothrium salvelini were found occurring in the stomach, intestine, and pyloric caeca. Philonema sp. nematodes occurred in gonads, on the peritoneum, and in the body cavity. The latter housed also another nematode which could not be identified. Females of the copepod Salmincola edwardsii were found on the gills. The data collected made it possible to determine the invasion incidence, intensity, mean intensity, and mean invasion intensity in population.
