Masu salmon (Oncorhynchus masou masou)

The Masu salmon (Oncorhynchus masou masou) is a freshwater fish of the family Salmonidae. Native range: Northwest Pacific, Sea of Okhotsk and Sea of Japan; northern Japan and eastern Korea Peninsula.

Biology

The fluviatile form generally inhabits headwaters and often maintains a territory; it feeds mainly on insects but also on small crustaceans and fishes. The sea-run form goes downstream forming schools, and after a short stay in the brackish zone enters the sea where it feeds on small fishes and pelagic crustaceans. Oviparous. Eggs are buried in unguarded nests. Marketed fresh and frozen; eaten broiled and baked.
