Parasites causing disease in wild and cultured fish in Newfoundland
This study, based on field and laboratory observations, investigated the role of parasites as the cause of disease outbreaks and mass mortality in wild and cultured fish in Newfoundland over three decades. One ciliated protozoan, Trichodina jadranica (Ciliophora), and Loma branchialis (Microspora) w...
