abstract
山梨県産魚類から報告されている寄生虫の目録を作成した.本論文で山梨県から初めて記録したチョウモドキArgulus coregoniを含めて,扁形動物5種(単生類2種,吸虫類1種,条虫類2種),線形動物1種,鉤頭動物3種,節足動物3種(カイアシ類1種,エラオ類2種),微胞子虫類1種,キネトプラステア類2種,繊毛虫類1種の合計16種が報告され,野生魚からは僅か7種のみであった.チョウモドキは,2015年7月に大月市を流れる相模川水系葛野川の支流,浅川川で採集されたヤマメの体表から得られた.過去に魚類寄生虫研究が山梨県で不活発であった背景と原因をこの県で流行していた日本住血吸虫病との関連で考察した.山梨県の本病は1996年に終息したことから,今後,活発な魚類寄生虫相研究が望まれる.
abstract
A checklist of the parasites of freshwater fishes of Yamanashi Prefecture, central Japan, is compiled based on the literature published for 103 years from 1914 to 2016. Only 16 species of the parasites have been reported from the prefecture: Monogenea (2 species), Trematoda (1), Cestoda (2), Acanthocephala (3), Nematoda (1), Copepoda (1), Branchiura (2), Microsporea (1), Kinetoplastea (2), and Phyllopharyngea (1). Argulus coregoni Thorell, 1864 (Branchiura) was collected in 2015 from masu salmon, Oncorhynchus masou masou (Brevoort, 1856), in the Asakawa River, a tributary of the Kuzuno River within the Sagami River system, in Ōtsuki City, Yamanashi Prefecture, and this collection is included in the checklist as a new prefectural record for A. coregoni. The reason for the past inactive research on the fish parasites of this prefecture is discussed in relation to the occurrence of a seriously pathogenic trematode Schistosoma japonicum (Katsurada, 1904) whose free-swimming cercariae infect humans during water contact. This parasite was successfully eradiated from Yamanashi Prefecture by 1996, and much more work is needed to clarify the fauna of the fish parasites of the prefecture.
