Report of the Working Group on Pathology and Diseases of Marine Organisms (WGPDMO)

The group produced a report on new disease trends in wild and farmed fish and shellfish in the ICES area, based on national reports received from 14 member coun-tries. Amoebic gill disease, which was reported as increasing in Norway in the 2014 report, has spread even further and the first cases of AGD were reported in Canada and the Faroe Islands. A new virus (virus Y) was reported in farmed rainbow trout in Norway with pathological lesions similar to those reported for heart & skeletal mus-cle inflammation (HSMI). A number of shellfish pathogens have expanded their range, with Bonamia ostreae reported in flat oysters in Denmark and the OsHV-1μVar in Pacific oysters in Norwegian and Swedish waters.
