広島県内の飼育ニシキゴイから得たチョウとわが国のコイに寄生するチョウに関する知見の総括 Argulus japonicus (Branchiura: Argulidae) from a koi carp Cyprinus carpio reared in Hiroshima Prefecture, western Japan, with a review of the biology of A. japonicus parasitic on common carp and koi carp in Japan 長澤, 和也 ナガサワ, カズヤ Nagasawa, Kazuya 0000000111671801 鹿児島大学 永井, 崇裕 Nagai, T. open access 鹿児島県自然環境保全協会 本文, 正誤表 One adult male of Argulus japonicus Theile, 1900 was collected from the body surface near the pectoral fin of a koi carp Cyprinus carpio Linnaeus, 1758 (Cypriniformes: Cyprinidae) reared by a carp hobbyist in a garden pond in Akiota, Hiroshima Prefecture, western Honshu, Japan. The male collected is briefly described. This is the second specimen-based record of A. japonicus from Hiroshima Prefecture, where the species was previously found from silver crucian carp Carassius sp. in the Kurose River. Based on the literature published between 1900 and 2023, this paper also reviews the biology of A. japonicus infecting common carp and koi carp in Japan. This parasite has been recorded from common carp and koi carp reared in 12 prefectures (Hokkaido, Ibaraki, Tokyo, Kanagawa, Ishikawa, Shiga, Mie, Osaka, Hyogo, Hiroshima, Yamaguchi, and Kagoshima) and from wild common carp in two prefectures (Miyagi and Shimane). This indicates that A. japonicus often utilizes captive common carp and koi carp as its hosts and is one of the important parasites of these fishes in Japan. In ponds rearing common carp in central Japan, free-swimming individuals of A. japonicus are highly abundant in warm water months but decrease in early winter. This species usually overwinters as eggs, but a few adults may survive in winter months. A secondary bacterial infection has been suggested to result from A. japonicus infection. 鹿児島県自然環境保全協会 2023-12-03 jpn journal article VoR http://hdl.handle.net/10232/0002000606 https://ir.kagoshima-u.ac.jp/records/2000606 18827551 AA12599025 Nature of Kagoshima 50 109 114 https://ir.kagoshima-u.ac.jp/record/2000606/files/AA12599025_50_p109-114.pdf application/pdf 925.2 KB 2024-11-13 2023-12-03 https://ir.kagoshima-u.ac.jp/record/2000606/files/AA12599025_50_p109-114_erratum.pdf application/pdf 129.5 KB 2024-11-13 2023-12-03
