The infection prevalences in the caged rainbow trout were 100% and 75%, and the mean abundances were 20.8 and 18.1 ind., in May and October, respectively. There were no significant differences between the parasite abundance distributions in these two months, likely indicating similar levels of resistance to the infection.
