The satsukimasu salmon,[1] red-spotted masu salmon[2] or amago[2] (Oncorhynchus masou ishikawai) is a salmonid fish in the Pacific salmon genus Oncorhynchus. It is endemic to Japan.

It was initially described as a distinct species and was cited as such by IUCN,[1] but it is more lately often considered a subspecies of the masu salmon or seema (Oncorhynchus masou)[2]. Others, including FishBase,[3] and Catalog of Fishes[4] do not consider it taxonomically distinct from O. masou masou.

The Iwame trout in turn was recently confirmed to refer in part to an unspotted recessive morph of the amago.[2]
