Summary The occurrence and microhabitat distribution of Dermocystidium percae on perch ( Perca fluviatilis ) was investigated in four sites in the lower Thames Valley, south‐east England. Fish were infected at all sites, with the highest prevalence occurring in a commercial fishery and the lowest in a large impounded water storage reservoir. The microhabitat distribution of D. percae cysts on the perch favoured the dorsal and anal fins, in contrast to previous studies, although a single occurrence on the gills was reported. The role of host stress on the prevalence of D. percae is discussed.
