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.
The Amur River or Heilong River is a perennial river in Northeast Asia, forming the natural border between the Russian Far East and Northeast China. The Amur proper is 2,824 km (1,755 mi) long, and has a drainage basin of 1,855,000 km2 (716,000 sq mi). If including its main stem tributary, the Argun, the Amur is 4,444 km (2,761 mi) long, making it the world's tenth longest river.
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.
Siberian taimen, also known as the common taimen, Siberian giant trout or Siberian salmon, is a species of salmon-like ray-finned fish from the genus Hucho in the family Salmonidae. These fish are found in rivers in Siberia and adjacent regions, and are harvested throughout the year.
Salmo is a genus of ray-finned fish from the subfamily Salmoninae of family Salmonidae, and is part of the tribe Salmonini along with the sister genera Salvelinus and Salvethymus. Almost all Salmo species are native only in the Old World, the only exception being the Atlantic salmon, which is also naturally found across the North Atlantic in eastern North America.
The Ussuri or Wusuli is a river that runs through Khabarovsk and Primorsky Krais, Russia and the southeast region of Northeast China. It rises in the Sikhote-Alin mountain range, flowing north and forming part of the Sino-Russian border, until it joins the Amur as a tributary to it near Khabarovsk. It is approximately 897 km (557 mi) long. The Ussuri drains the Ussuri basin, which covers 193,000 km2 (75,000 sq mi). Its waters come from rain (60%), snow (30–35%), and subterranean springs. The average discharge is 1,620 m3/s (57,000 cu ft/s), and the average elevation is 1,682 metres (5,518 ft).
Thymallus yaluensis, also known as Yalu grayling, is a putative species of freshwater ray-finned fish from the genus Thymallus in the family Salmonidae. It is endemic to the upper Yalu River on the China-North Korea border.
Salvelinus curilus is a species of anadromous fish in the salmon family. It inhabits the waters of Russian Far East in the Kurile Islands, Sakhalin, Primorye and also Korea and Japan. It has mostly been considered a subspecies of the Dolly Varden trout Salvelinus malma, with the name Salvelinus malma krascheninnikova, and referred to as the southern Dolly Varden or Asian southern form Dolly Varden trout.
Leymus is a genus of plants in the grass family Poaceae (Gramineae). It is widespread across Europe, Asia, and the Americas.
The Amur leopard is a leopard subspecies native to the Primorye region of southeastern Russia and northern China. It is listed as Critically Endangered on the IUCN Red List, as in 2007, only 19–26 wild leopards were estimated to survive in southeastern Russia and northeastern China.
Brachymystax lenok, the sharp-snouted lenok, is a salmonid fish distributed in rivers and lakes in northeastern Asia. It formerly included the blunt-snouted lenok, but recent authorities typically treat the latter as a separate species, B. tumensis, based on differences in morphology and genetics.
Li Sizhong was an ichthyologist with the Institute of Zoology (中国科学院动物研究所) at the Chinese Academy of Sciences. Throughout his research career, he made numerous discoveries of new fish species, and published many books and research papers describing the fauna and geographical distribution of fishes in China and beyond. He translated and helped publication of the Chinese editions of Fishes of the World and Fish Migration. Li was the major author of two published volumes in the Fauna Sinica monograph series, systematically reviewing and describing orders of bony fishes that include flat fish, cod, silverside, pearlfish, killifish, flying fish, etc. in or near China. He had authored at least 60 academic papers, written over 40 popular science articles about fish on Chinese newspapers and magazines, and been responsible for compiling and editing fish-related entries in several standard reference books. His works on freshwater ichthyofauna of China as well as other aspects of ichthyology are considered to be among some of the most notable in the Chinese ichthyology literature.
Brachymystax tumensis, commonly known as the blunt-snouted lenok or Tumen lenok, is a salmonid fish distributed in rivers and lakes in Eastern Asia. It was formerly included in the more widespread species Brachymystax lenok, but more recent research based on differences in morphology and genetics have justified a distinction of the two species.
Nora Nature Reserve is a Russian 'zapovednik' on the northeastern part of the Amur-Zeya lowland plain between the Nora River and the Selemdzha River. The reserve is known for its herd of Norsk roe deer, the largest migrating herd in the world, with 5,000-7,000 individuals migrating through every September. The terrain is half forested, and half wetland and bogs, in the meeting zone between Siberian, Okhotsk, and Mongolian plant and animal communities. The reserve is situated in the Selemdzhinsky District of Amur Oblast.
Brachymystax savinovi is a salmonid fish species endemic to Markakol Lake and adjacent rivers in eastern Kazakhstan. It was formerly included in the more widespread species Brachymystax lenok.
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 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.
Salvelinus alpinus erythrinus, also known as Baikal charr or davatchan, is a subspecies of freshwater fish in the salmon family. It is endemic to the mountains north of Lake Baikal in the Russian Far East. The fish is edible and it is reported that the population of the species shrunk rapidly over the recent years due to over-fishing.
