Tanakia somjinensis, also known as the Seomjin Bitterling, is an endangered species of ray-finned fish in the genus Tanakia . [1]
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 considered 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 suborder Clupeoidei. The term 'sardine' was first used in English during the early 15th century; a somewhat dubious etymology says it comes from the Italian island of Sardinia, around which sardines were once supposedly abundant.
Wobbegong is the common name given to the 12 species of carpet sharks in the family Orectolobidae. They are found in shallow temperate and tropical waters of the western Pacific Ocean and eastern Indian Ocean, chiefly around Australia and Indonesia, although one species occurs as far north as Japan. The word wobbegong is believed to come from an Australian Aboriginal language, meaning "shaggy beard", referring to the growths around the mouth of the shark of the western Pacific.
The billfish are a group of saltwater predatory fish characterised by prominent pointed bills (rostra), and by their large size; some are longer than 4 m (13 ft). Extant billfish include sailfish and marlin, which make up the family Istiophoridae; and swordfish, sole member of the family Xiphiidae. They are often apex predators which feed on a wide variety of smaller fish, crustaceans and cephalopods. These two families are sometimes classified as belonging to the order Istiophoriformes, a group which originated around 71 million years ago in the Late Cretaceous, with the two families diverging around 15 million years ago in the Late Miocene. However, they are also classified as being closely related to the mackerels and tuna within the suborder Scombroidei of the order Perciformes. However, the 5th edition of the Fishes of the World does recognise the Istiophoriformes as a valid order, albeit including the Sphyraenidae, the barracudas.
Shigeho Tanaka was a Japanese ichthyologist and professor of zoology at the Imperial University of Tokyo. He published numerous works on fishes and sharks and co-authored a book on Japanese fish with famous American scientist David Starr Jordan.
Tanakia is a genus of cyprinid fish, consisting of seven species that occur in Eastern Asia. The type species is the Tanakia limbata.
The oily bitterling is a temperate freshwater fish belonging to the Acheilognathinae sub-family of the family Cyprinidae. It originates in creeks with fast-running water in central and southern Japan. It was originally described as Capoeta limbata by Temminck & Schlegel in 1846, and has also been referred to as Acheilognathus limbatus and Acheilognathus limbata in scientific literature. The fish reaches a size of up to 6 cm (2.4 in) TL.
The bitterling-like cyprinids form the cyprinid subfamily Acheilognathinae. This subfamily contains seven genera, although the Khanka spiny bitterling is often placed in Acheilognathus, and at least 75 described species to date. Over half of the species are in the genus Acheilognathus.
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.
Tanakia koreensis is a cyprinid found in Korea which can grow to a size of 8 centimeters.
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.
