Lenoks, otherwise known as Asiatic trout or Manchurian trout,[3] are salmonid fish of the genus Brachymystax, native to rivers and lakes in Mongolia, Kazakhstan, wider Siberia (including Russian Far East), Northern China and Korea. There are three species in this genus recognised by FishBase:[2]

Brachymystax lenok (Pallas, 1773) – sharp-snouted lenok[4]
Brachymystax savinovi Mitrofanov, 1959
Brachymystax tumensis T. Mori, 1930 – blunt-snouted lenok[4]
A fourth species, Brachymystax tsinlingensis S. C. Li, 1966, was revalidated in 2015.[6]

Traditionally, only B. lenok was recognized, including both sharp-snouted and blunt-snouted forms. Based on differences in morphology and genetics, the blunt-snouted form was split off as a separate species, B. tumensis.[4][7][8][9] Hybrids between these two are known.[9] The validity of the third species, B. savinovi, is questionable,[10] and it is often considered a synonym of B. lenok.[4][11] The name B. savinovi has occasionally been used for the blunt-snouted lenok,[12] but this is incorrect.[4][9]

Appearance
Lenoks can be sharp-snouted (B. lenok) or blunt-snouted (B. tumensis).[4][9] Traditionally both these were included in B. lenok, but today they are generally recognized as separate. They are relatively round in shape, and speckled with dark brown spots.[3] Their ventrals are usually colored a reddish hue, and their pectoral fins yellowish.[13] They weigh up to 15 kilograms (33 lb),[14] and can reach a total length of 1.05 m (3.4 ft).[15]

Habitat, range and status
Lenoks tend to live in rivers of any sort, but usually upstream, where the water is colder.[16] They are also found in lakes such as Baikal.[4]

As currently defined, the sharp-snouted lenok (B. lenok) is widespread in central and eastern Russia, and also found widely in northern Mongolia, locally in northeastern Kazakhstan (Irtysh Basin) and northeastern China (Amur Basin).[4][7][12] The blunt-snouted lenok (B. tumensis) is found widely in southeastern Russia and more locally in northeastern and central parts of the country, as well as northeastern Mongolia (Amur Basin), northern China and Korea.[4][12] Although the two generally are found in separate areas, there are also regions where their ranges overlap such as the Amur Basin.[4][5][7][9]

The recently revalidated Brachymystax tsinlingensis is restricted to streams in the Yellow and Yangtze basins in the Qinling Mountains of China.[6]

Though overall widespread, lenoks in South Korea are now on the verge of extinction due to deforestation and they have also declined in China.[16][17]

History
In the Korean peninsula, lenoks were landlocked inland during the glacial epoch.[Salmonidae /sælˈmɒnɪdiː/ is a family of ray-finned fish that constitutes the only currently extant family in the order Salmoniformes /sælˈmɒnɪfɔːrmiːz/. It includes salmon (both Atlantic and Pacific species), trout (both ocean-going and landlocked), chars, freshwater whitefishes, graylings, taimens and lenoks, which are collectively known as the salmonids ("salmon-like fish"). The Atlantic salmon (Salmo salar), whose Latin name became that of its genus Salmo, also derives the family and order names.

Salmonids have a relatively primitive appearance among the teleost fish, with the pelvic fins being placed far back, and an adipose fin towards the rear of the back. They are slender fish, with rounded scales and forked tails. Their mouths contain a single row of sharp teeth.[2] Although the smallest species is just 13 cm (5.1 in) long as an adult, most are much larger, with the largest reaching 2 m (6 ft 7 in).[1]

All salmonids spawn in fresh water, but in many cases, the fish spend most of their lives at sea, returning to the rivers only to reproduce. This lifecycle is described as anadromous. They are carnivorous predators, feeding on small crustaceans, aquatic insects and smaller fish.Current salmonids comprise three lineages, taxonomically treated as subfamilies: Coregoninae (freshwater whitefishes), Thymallinae (graylings), and Salmoninae (trout, salmon, char, taimens and lenoks). Generally, all three lineages are accepted to allocate a suite of derived traits indicating a monophyletic group.[3]

The Salmonidae first appear in the fossil record in the Middle Eocene with Eosalmo driftwoodensis, which was first described from fossils found at Driftwood Creek, central British Columbia. This genus shares traits found in all three subfamily lineages. Hence, E. driftwoodensis is an archaic salmonid, representing an important stage in salmonid evolution.[3]
