Open encyclopedia reference
The big-scaled redfin (Pseudaspius hakonensis), also known as the Japanese dace and ugui (鯎 or 鵜喰), is a medium-sized Asian species of ray-finned fish belonging to the family Leuciscidae, which includes the daces, chubs, true minnows and related fishes. First described by Albert Günther in 1877 as Leuciscus hakonensis, it was the type specimen of the genus Tribolodon, having been described again as Tribolodon punctatum by Henri Émile Sauvage when he established that genus in 1883. It is the most widely distributed of the Pseudaspius species, found over much of the Sea of Japan. It is known to carry a number of parasites, including the trematode species Centrocestus armatus (for which it is a second intermediate host), and the copepod species Ergasilus fidiformis, which is carried in the fish's gills.
