Miyabe charr (Salvelinus malma miyabei)

Scientific name: Salvelinus malma miyabei Oshima, 1938

The Miyabe charr (Salvelinus malma miyabei) is a freshwater fish of the family Salmonidae.

Biology

Land-locked subspecies that occurs only in Lake Shikaribetsu and connecting rivers in Japan. In the lake, two populations exist, pelagic feeding on plankton and bottom dwellers. Spawning occurs in rivers between September and November. Juveniles remain in the river; they move into the lake the following autumn. The bottom dwelling population may spawn in the lake.
