The pond smelt, Hypormesus olidus (PALLAS), migrates inherently into the sea and ascends for spawning to streams, but the land-locked form also occurs commonly in lakes and pond in Japan.

Of the fishes of the River Ishikari, the school of the present waterway which ascends from the sea differs from the fish of the old waterway in the morphological characters such as the body length, the scale structure and the number of vertebrae.
Consequently, each school of both waterways is independent ecologically with each other, The fish of the present waterway migrates into the sea, while the school of the old waterway stays through the life in fresh water, in spite of the presence of passage to the sea.
