Abstract.-Adult sockeye salmon Oncorhynchus nerka from the Ozernaya River near the outlet of Lake Kuril were infected with Myxobolus arcticus (Myxozoa) in the brain and spinal cord and with Philonema oncorhynchi (Nematoda) in the peritoneal cavity. Some of these sockeye salmon were affected by light...

| Summary: | Abstract.-Adult sockeye salmon Oncorhynchus nerka from the Ozernaya River near the outlet of Lake Kuril were infected with Myxobolus arcticus (Myxozoa) in the brain and spinal cord and with Philonema oncorhynchi (Nematoda) in the peritoneal cavity. Some of these sockeye salmon were affected by light visceral adhesions. This pathological condition was found in male fish only. Myxobolus arcticus was also found in the brain of adult Dolly Varden Salvelinus malma from a river flowing into Lake Kuril. There was no substantial difference in spore measurement of M. arcticus from salmonids among Kamchatka (Russia), Hokkaido (Japan), and British Columbia (Canada). The Dolly Varden carried Salmincola carpionis (Copepoda) on the roof and floor of the buccal cavity and Anisakis |
