ウスメバル養成親魚に見出された寄生性カイアシ類 Clavella parva Infection with the Parasitic Copepod Clavella parva (Lernaeopodidae) in Gold-eye Rockfish Sebastes thompsoni Broodstock in Japan
Infection with the lernaeopodid copepod <i>Clavella parva</i> was found in gold-eye rockfish <i>Sebastes thompsoni</i> broodstock kept at an aquaculture institute in Aomori Prefecture, northern Japan. A description of female and male adults of <i>C. parva</i> is given. This is the first record of <i>C. parva</i> 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. No infection was observed again after manual removal of the copepods. The species occurred most abundantly on the dorsal and caudal fins, followed by the anal fin. Literary information on the geographical distribution and hosts of <i>C. parva</i> is reviewed.
