Infection with the lernaeopodid copepod Clavella parva was found in gold-eye rockfish Sebastes thompsoni broodstock kept at an aquaculture institute in Aomori Prefecture, northern Japan. A description of female and male adults of C. parva is given. This is the first record of C. parva from Japan and a new host record. The parasite was likely introduced to the institute by the fish that had been reared in cages kept in natural waters.
