【 摘 要 】

ABSTRACT: In March 2002, 3 seawater farms in northern Norway experienced high mortality among Atlantic salmon postsmolts. A myxosporean parasite assigned to the genus Parvicapsula was detected in the pseudobranchs of diseased fish, and extensivedestruction of this organ was observed. The parasite was also found in the gills, liver and kidney of some fish. Based on host species, spore morphology, and the unusual site preference of the parasite, it is likely that it represents a hithertoundescribed species. The diseased fish had been transferred to seawater in September 2001, and it is believed that the infection took place shortly after exposure to seawater. The source of infection is unknown.
