Description
Ischikauia steenackeri, known in Japan as wataka, is a slender cyprinid of the family Cyprinidae endemic to Japan, particularly Lake Biwa and adjacent waters. The species has an elongate, laterally compressed, silvery body with an upward-pointing mouth and reaches about 30 cm. It lives in schools in the open water column of lakes and slow-flowing rivers.
