The lenoks (Otherwise known as Asiatic trouts or Manchurian trouts[2]) are a genus, Brachymystax, of salmonid fishes. It contains three species living in Mongolia, Siberia, the far East of Russia, Northern China, the Sea of Japan[3] and South Korea.[2][4][5]

Appearance

Lenoks can be sharp-nosed or blunt-nosed. Populations of blunt-nosed Lenoks are generally found in different areas than populations of sharp-nosed Lenoks.[4] They typically grow to about 20 inches.[6] They are relatively round in shape, and speckled with dark brown spots.[2][7] They usually weigh up to 15 kilos.[7] Their ventrals are usually colored a reddish hue, and their pectoral fins yellowish.[8]

Lenoks in Korea are now on the verge of extinction due to deforestation.[5]

Habitat

Lenoks tend to live in rivers of any sort,[9] but usually upstream, where the water is colder.[5]

History

During the glacial epoch, Lenoks were landlocked inland of the Korean peninsula.[5]
