abstract
The piscicolid leech Limnotrachelobdella okae (Moore, 1924) was found attached to the skin near the pectoral fin of a cherry salmon Oncorhynchus masou masou caught at a depth of 180-200 m in the western North Pacific Ocean off the east coast of northern Honshu, Japan. This is the first record of L. okae from the ocean-swimming salmonid in neritic deep waters although it is not known where the fish was infected. L. okae has been generally believed to be a parasite of both marine and freshwater fishes, but it is concluded, based on the present results and the literature review on the host and distributional records, that the leech is a coastal marine or brackish-water species: the infection occurs only in salt waters, and anadromous fishes, such as salmonids, carry the leech to fresh waters, where it can survive for a certain period.
