The lakeweed chub, Ischikauia steenackeri (Sauvage, 1883), was originally distributed in the Yodo River system including Lake Biwa, central Japan, and has recently established its populations as a domestic alien species in various inland waters in western and central Japan, including Kyushu. An adult female of Argulus japonicus Thiele, 1900 was collected from the body surface of a lakeweed chub in an irrigation canal connected to the Hase River, a tributary of the Nishi River within the Onga River system in Fukuoka Prefecture, northern Kyushu. This repersents a new prefectural and host records for A. japonicus. This parasite is considered not to have been introduced to the sampling site by I. steenackeri but to naturally occur in the river system.
