Pseudaspius sachalinensis is a species of fish in the family Cyprinidae. It is endemic to Japan and Sakhalin.
A tuna is a saltwater fish that belongs to the tribe Thunnini, a subgrouping of the Scombridae (mackerel) family. The Thunnini comprise 15 species across five genera, the sizes of which vary greatly, ranging from the bullet tuna up to the Atlantic bluefin tuna, which averages 2 m (6.6 ft) and is believed to live up to 50 years.
Mackerel is a common name applied to a number of different species of pelagic fish, mostly from the family Scombridae. They are found in both temperate and tropical seas, mostly living along the coast or offshore in the oceanic environment.
Herring are forage fish, mostly belonging to the family of Clupeidae.
The term carp is a generic common name for numerous species of freshwater fish from the family Cyprinidae, a very large clade of ray-finned fish mostly native to Eurasia. While carp are prized quarries and are valued as both food and ornamental fish in many parts of the Old World, they are generally considered useless trash fish and invasive pests in many parts of Africa, Australia and most of the United States.
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is an inventory of the global conservation status and extinction risk of biological species. A series of Regional Red Lists, which assess the risk of extinction to species within a political management unit, are also produced by countries and organizations.
Sardine and pilchard are common names for various species of small, oily forage fish in the herring family Clupeidae. The term 'sardine' was first used in English during the early 15th century; a somewhat dubious folk etymology says it comes from the Italian island of Sardinia, around which sardines were once supposedly abundant.
Thunnus is a genus of ocean-dwelling, ray-finned bony fish from the mackerel family, Scombridae. More specifically, Thunnus is one of five genera which make up the tribe Thunnini – a tribe that is collectively known as the tunas. Also called the true tunas or real tunas, Thunnus consists of eight species of tuna, divided into two subgenera.
The Sakhalin vole is a species of rodent in the family Cricetidae. It is found only in Russia.
Abies sachalinensis, the Sakhalin fir, is a species of conifer in the family Pinaceae. It is found in Sakhalin island and southern Kurils (Russia), and also in northern Hokkaido (Japan). The first discovery by a European was by Carl Friedrich Schmidt (1832-1908), the Baltic German botanist, on the Russian island of Sakhalin in 1866, but he did not introduce it to Europe. The plant was re-discovered by the English plant-collector, Charles Maries in 1877 near Aomori on the main Japanese island of Honshū, who initially thought it to be a variety of Abies veitchii. Abies nephrolepis is known to be the closest relative, which exists on the mainland just west of the range of Sakhalin fir.
Scaphirhynchus is a genus of sturgeons native to North America. All species in this genus are considered to be threatened with extinction or worse. As of 2023, the pallid sturgeon and the Alabama sturgeon are critically endangered according to the International Union for Conservation of Nature.
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching, and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration.
Eels are ray-finned fish belonging to the order Anguilliformes, which consists of eight suborders, 20 families, 164 genera, and about 1000 species. Eels undergo considerable development from the early larval stage to the eventual adult stage and are usually predators.
An anchovy is a small, common forage fish of the family Engraulidae. Most species are found in marine waters, but several will enter brackish water, and some in South America are restricted to fresh water.
Opsarius is a genus of fish. Its representatives can be found in a variety of countries in South East Asia. These countries include Cambodia, Laos, Thailand, Myanmar, India, and China. Certain species of Opsarius are considered endemic to their respective habitats; such as Opsarius cocsa and Opsariusmaculatus which are endemic to India.
Pseudaspius leptocephalus, the redfin, is a species of cyprinid fish found in eastern Asia where it occurs in the countries of Russia, Mongolia and China.
Pseudaspius, commonly called redfin daces, are a genus of cyprinid freshwater fish found in eastern Asia, specifically the countries of Russia, Mongolia, China and Japan.
The big-scaled redfin, also known as the Japanese dace and ugui, is a medium-sized Asian fish. First described by Albert Günther in 1877 as Leuciscus hakonensis, it was the type specimen of the genus Tribolodon, having been described again as Tribolodon punctatum by Henri Émile Sauvage when he established that genus in 1883. It is the most widely distributed of the Pseudaspius species, found over much of the Sea of Japan. It is known to carry a number of parasites, including the trematode species Centrocestus armatus, and the copepod species Ergasilus fidiformis, which is carried in the fish's gills.
Pseudaspius nakamurai is a species of fish in the family Cyprinidae. It is endemic to Japan.
