Salmon lice evasion, susceptibility, retention, and development differ amongst host salmonid species.
With different ecological characteristics amongst salmonid species, their response to parasitic infestation is likely to vary according to their spatial and temporal overlap with the parasite. This study investigated the host–parasite interactions amongst three species of salmonids and the ectoparas...
