Utilisation of brown trout by Acanthocephalus clavula (Acanthocephala) in brown trout (Salmo trutta) in an Irish lake: is this evidence of a host shift?
PUBLISHED The population biology of the fish acanthocephalan Acanthocephalus clavula was described from 161 wild brown trout, Salmo trutta sampled over a two-year period in Clogher Lake in the west of Ireland. Overall prevalence of the parasite was 86% and the mean abundance was 53 worms per fish. D...
