Importance of lake characteristics in structuring parasite communities of salmonids from insular Newfoundland
Metazoan parasites of Salmo salar and Salvelinus fontinalis were studied at eight sites in insular Newfoundland. The locations included water bodies of various sizes (<1, 1–100, and >100 ha) and depths (<1, 1–5, and >5 m). Nine of 14 parasite species were salmonid specialists and general...
