Samples of crucian carp with unusual morphology, collected from the Yufutsu Moor, Hokkaido, Japan, were identified as Carassius sp.on the basis of having uniserial pharyngeal teeth and barbels absent. Although the population differed from other Japanese congeners by having a larger head and shallower caudal peduncle, it also displayed some characters attributable to C. carassius, including a strong black cross bar on the caudal peduncle in young individuals, subterminal mouth and five dorsal unbranched rays, such characters corresponding to C. carassius morpha humilis sensu Breg (1964). All individuals were female triploids, but were clearly different from “Ginbuna”, the well-known Japanese triploid Carassius group, in morphological characters and body color. Although C. carassius has not yet been recorded from Hokkaido, it seems likely to have been one of the parental species resulting in this unique population.
