Long-Term Gyrodactylus lomi Infection on Isolated Juvenile Chub, Leuciscus cephalus

Abstract

Previous studies on long term gyrodactylid infections on isolated fish have shown that for the majority of Gyrodactylus-fish interactions, infections peak at a maximum level and then decline as the host mounts an effective immune response. In the current study, juvenile chub collected from the wild still harboured Gyrodactylus lomi infections after 6 - 10 months in the laboratory despite being individually maintained at 12 C.
