Thymallus yaluensis, also known as Yalu grayling, is a putative species of freshwater ray-finned fish from the genus Thymallus (graylings) in the family Salmonidae. It is endemic to the upper Yalu River on the China-North Korea border. [1]
Thymallus yaluensis is a small fish, the maximum recorded length is {[cvt|20|cm}}. [1] "It has the most beautiful form and fins of a freshwater fish" in Korea. [1]
Some confusion exists about the identity of T. yaluensis, as it is very similar in form to the Arctic grayling (Thymallus arcticus), and has mostly been treated as a subspecies T. a. yaluensis, [2] although FishBase treats it as an independent species. [1] According to mitochondrial DNA, T. yaluensis is, however, inseparable from the Amur grayling (Thymallus grubii), and was suggested to be a junior synonym of that. [3] Confusingly, it has also been reported from widely separate regions including Siberia, the Alps in Europe, and the northern Mississippi River drainage in North America.[ citation needed ]
Salmonidae is a family of ray-finned fish that constitutes the only currently extant family in the order Salmoniformes, consisting of 11 extant genera and over 200 species collectively known as "salmonids" or "salmonoids". The family includes salmon, trout, char, graylings, freshwater whitefishes, taimens and lenoks, all coldwater mid-level predatory fish that inhabit the subarctic and cool temperate waters of the Northern Hemisphere. The Atlantic salmon, whose Latin name became that of its genus Salmo, is also the eponym of the family and order names.
Cypriniformes is an order of ray-finned fish, which includes many families and genera of cyprinid fish, such as barbs, gobies, loaches, botias, and minnows. Cypriniformes is an “order-within-an-order”, placed under the superorder Ostariophysi—which is also made up of cyprinid, ostariophysin fishes. The order contains 11-12 families, over 400 genera, and more than 4,250 named species; new species are regularly described, and new genera are recognized frequently. Cyprinids are most diverse in South and Southeast Asia, but are entirely absent from Australia and South America. At 112 years old, the longest-lived cypriniform fish documented is the bigmouth buffalo.
Thymallus, commonly known as graylings, is a genus of freshwater ray-finned fish and the only genus within the subfamily Thymallinae of the family Salmonidae. Although all Thymallus species can be generically called graylings, without specific qualification the term "grayling" typically refers to the type species Thymallus thymallus, the European grayling.
Thymallus thymallus, the grayling or European grayling, is a species of freshwater fish in the salmon family Salmonidae. It is the only species of the genus Thymallus native to Europe, where it is widespread from the United Kingdom and France to the Ural Mountains in Russia, and Balkans on the south-east, but does not occur in the southern parts of the continent. It was introduced to Morocco in 1948, but it does not appear to have become established there.
The Arctic grayling is a species of freshwater fish in the salmon family Salmonidae. T. arcticus is widespread throughout the Arctic and Pacific drainages in Canada, Alaska, and Siberia, as well as the upper Missouri River drainage in Montana. In the U.S. state of Arizona, an introduced population is found in the Lee Valley and other lakes in the White Mountains. They were also stocked at Toppings Lake by the Teton Range and in lakes in the high Uinta Mountains in Utah, as well as alpine lakes of the Boulder Mountains (Idaho) in central Idaho.
The Amur grayling is a species of freshwater ray-finned fish from the genus Thymallus (graylings) of the family Salmonidae, endemic to the Amur basin in Russian Far East and Northeast China and also the Onon and Kherlen basins in Mongolia. It is sometimes difficult to differentiate the species with the Lower Amur grayling. It is seen as a game fish and food fish in Russian Far East and the Chinese Heilongjiang province.
The East Siberian grayling(Thymallus pallasii) is a grayling in the salmon family Salmonidae. Males can reach a size of 44 cm (17 in).
Grebe Lake is a 156 acres (0.63 km2) backcountry lake in Yellowstone National Park most noted for its population of Arctic grayling. Grebe Lake comprises the headwaters of the Gibbon River. Grebe Lake is located approximately 3.1 miles (5.0 km) north of the Norris-Canyon section of the Grand Loop Road. The trail to the lake passes through mostly level Lodgepole Pine forest and open meadows. The lake was named by J.P. Iddings, a geologist with the Arnold Hague geologic surveys. There are four backcountry campsites located on the lake.

The Montana Arctic grayling is a North American freshwater fish in the salmon family Salmonidae. The Montana Arctic grayling, native to the upper Missouri River basin in Montana and Wyoming, is a disjunct population or subspecies of the more widespread Arctic grayling. It occurs in fluvial and adfluvial, lacustrine forms. The Montana grayling is a species of special concern in Montana and had candidate status for listing under the national Endangered Species Act. It underwent a comprehensive status review by the U.S. Fish and Wildlife Service, which in 2014 decided not to list it as threatened or endangered. Current surviving native populations in the Big Hole River and Red Rock River drainages represent approximately four percent of the subspecies' historical range.
Thymallus baicalensis, also known as the Baikal black grayling, is a Siberian freshwater fish species in the salmon family Salmonidae.
Thymallus brevipinnis is a species of freshwater ray-finned fish belonging to the subfamily Thymallinae, the graylings, part of the family Salmonidae. This species is endemic to Lake Baikal in Siberia where it is benthopelagic. Some workers regard this taxon as a junior synonym of Thymallus baicalensis.
Thymallus ligericus, the Loire grayling, is a European freshwater fish species in the salmon family Salmonidae. The species is endemic to the upper Loire drainage in France, where it lives in medium to large foothill, canyon and plateau rivers of the mountainous regions.
The Kamchatka grayling is a grayling in the salmon family Salmonidae. The fish grows up to 50 cm (20 in). It is found in freshwater habitats of the Russian Far East, including the Kamchatka Peninsula, eastern part of Magadan Oblast and northwards to the southern Chukchi Peninsula.
The Mongolian grayling is a freshwater species of fish of the genus Thymallus endemic to the landlocked rivers in Mongolia, Inner Mongolia Province of China and nearby parts of Russian far east. It is considered to be the largest grayling species in the world, and hence viewed as an auspicious sign by local tribes.
Thymallus svetovidovi, also known as the Upper Yenisei grayling, is a species of freshwater fish in the salmon family. It is found in the upper reaches of the Yenisei River and in western Mongolia.
Thymallus tugarinae, also known as the Lower Amur grayling, is a species of freshwater fish in the salmon family. It is found in the lower reaches of the Amur river on the border of the Russian far east and Heilongjiang Province of China. It was first described in 2007 and is sometimes mistaken for the Amur grayling.
Thymallus flavomaculatus, also known as yellow-spotted grayling, is a species of brackish-water fish in the salmon family. It is found in Khabarovsk and Primorsky Krai of the Russian Far East, as well as the Sea of Japan and the Sea of Okhotsk. They usually live near or on the bottom of the water body.
