How fish‐helminth associations arise: an example from Arctic charr in Loch Rannoch
Three sympatric morphs of Arctic charr Salvelinus alpinus occur in Loch Rannoch, Scotland, and are identified by their differing head morphology and diet. These are small‐headed benthic, large‐headed benthic and pelagic morphs. Six species of endoparasitic helminth were found in the fish, but the mo...

Three sympatric morphs of Arctic charr Salvelinus alpinus occur in Loch Rannoch, Scotland, and are identified by their differing head morphology and diet.

Overall infections in pelagic charr were heavier than in large‐headed benthics, which were in turn heavier than in small‐headed benthics, even though benthic charr live longer than pelagics.
