Parasites as indicators of individual feeding specialization in Arctic charr during winter in northern Norway
The relationship between infection with the food‐transmitted parasites Diphyllobothrium dendriticum, D. ditremum (Cestoda) and Cystidicola farionis (Nematoda) and prey selection was studied in individual Arctic charr from Lake Takvatn, northern Norway. There was no correlation between parasites tran...
