Cyprinidae is a family of freshwater fish commonly called the carp or minnow family, including the carps, the true minnows, and their relatives the barbs and barbels, among others. Cyprinidae is the largest and most diverse fish family, and the largest vertebrate animal family overall, with about 3,000 species; only 1,270 of these remain extant, divided into about 200 valid genera. Cyprinids range from about 12 mm in size to the 3 m (9.8 ft) giant barb. By genus and species count, the family makes up more than two-thirds of the ostariophysian order Cypriniformes. The family name is derived from the Greek word kyprînos.
The Amur bitterling is a small fish of the carp family. It is sometimes just called "bitterling", which dates back to the time when the European bitterling was still considered conspecific with R. sericeus, and "bitterling" properly refers to any species in entire genus Rhodeus. The Amur bitterling is found in Siberia, while the European bitterling is found from European Russia westwards.
Danio is a genus of small freshwater fish in the family Cyprinidae found in South and Southeast Asia, commonly kept in aquaria. They are generally characterised by a pattern of horizontal stripes, rows of spots or vertical bars. Some species have two pairs of long barbels. Species of this genus consume various small aquatic insects, crustaceans and worms.
The rosy bitterling or Tairiku baratanago is a small freshwater fish belonging to the family Cyprinidae (carp), native to East Asia from the Amur River basin to the Pearl River basin.
Schizothorax is a genus of cyprinid fish found in southern and western China, through northern South Asia (Himalaya) and Central Asia, to Iran, with a single species, S. prophylax, in Turkey. They are primarily found in highland rivers, streams and lakes, although a few species occur in lower-lying locations, like Lake Balkhash and lakes of the Sistan Basin. Their scientific name means "cloven-breast", from Ancient Greek schízeïn (σχίζειν) 'to cleave' and thórax (θώραξ) 'breast-plate'. The western species are typically referred to as marinkas from their Russian name marinka (маринка), while the eastern species are usually called snowtrout. Although they do resemble trouts in habitus this is merely due to convergent evolution and they are by no means closely related apart from both being Teleostei: Cyprinids are in the teleost superorder Ostariophysi, while trouts are in the superorder Protacanthopterygii. Their ancestors must thus have diverged as early as the Triassic, more than 200 million years ago.
Sinocyclocheilus is a genus of freshwater fish in the family Cyprinidae that is endemic to Guangxi, Guizhou and Yunnan in China. Almost all of its species live in or around caves and most of these have adaptions typical of cavefish such as a lack of scales, lack of pigmentation and reduced eyes. Several species have an unusual hunchbacked appearance and some of the cave-dwellers have a "horn" on the back, the function of which is unclear. In contrast, the Sinocyclocheilus species that live aboveground, as well as a few found underground, show no clear cavefish adaptions. They are relatively small fish reaching up to 23 cm (9.1 in) in length. The individual species have small ranges and populations, leading to the status of most of the evaluated species as threatened. Many species populations in the genus have yet to be evaluated by the IUCN.
The Russian bitterling, or spiny bitterling, is a temperate freshwater fish belonging to the Acheilognathinae sub-family of the family Cyprinidae. It originates in the Amur River basin in Asia, and is found in China and Russia.
The Kyushu bitterling is a temperate freshwater fish belonging to the Acheilognathinae of the family Cyprinidae. It originates on Kyushu Island in Japan. It was originally described as Acanthorhodeus atremius by Jordan & Thompson in 1914. The fish reaches a size of up to 6 cm (2.5 in), and is native to freshwater habitats with a pH of 6.8 to 7.8, a hardness of 20 DH, and a temperature of 10 to 25 °C.
The European bitterling is a temperate freshwater fish belonging to the subfamily Acheilognathinae of the family Cyprinidae. It originates in Europe, ranging from the Rhone River basin in France to the Neva River in Russia. It was originally described as Cyprinus amarus by Marcus Elieser Bloch in 1782, and has been referred to in scientific literature as Rhodeus sericeus amarus. It is known simply as "the bitterling" in its native range, where it is the only species of its genus Rhodeus, and sometimes in the scientific literature, also, but this is technically wrong, being a leftover from the times when the European bitterling was united with its Siberian relative, the Amur bitterling, in R. sericeus. Properly, "bitterling" can refer to any species of Acheilognathus or Rhodeus.
Rhodeus smithii, sometimes known as the Japanese rosy bitterling, Japanese bitterling, or Nippon baratanago is a temperate freshwater fish belonging to the Acheilognathinae subfamily of the family Cyprinidae. It originates in stagnant waters in inland rivers in Japan. It was originally described as Achilognathus smithii by Charles Tate Regan in 1908, and is also referred to as Rhodeus ocellatus smithii in scientific literature.
Acheilognathus is a genus of cyprinid fish native to Asia. The name is derived from the Greek a, meaning "without", the Greek cheilos, meaning "lip", and the Greek gnathos, meaning "jaw".
The bitterling-like cyprinids form the cyprinid subfamily Acheilognathinae. This subfamily contains four genera, although the Khanka spiny bitterling is often placed in Acheilognathus, and at least 71 described species to date. Over half of the species are in the genus Acheilognathus.
Broda Otto Barnes was an American physician and professor of medicine who studied endocrine dysfunction, particularly hypothyroidism. In the 1970s, Barnes published several books arguing that hypothyroidism was underdiagnosed in the U.S. and was responsible for a wide range of health problems. Barnes' views on the prevalence of hypothyroidism were never widely accepted by the medical community and run counter to its current understanding of thyroid function, but they have been embraced by some elements of the alternative medicine community.
The striped bitterling is a species of freshwater ray-finned fish in the genus Acheilognathus. It is endemic to Lake Biwa and Lake Yogo in Japan. It typically grows to a length of 6.0 cm.
Acheilognathus macromandibularis is a species of freshwater ray-finned fish in the genus Acheilognathus. It is endemic to China. It grows to a maximum length of 5.2 cm.
Acheilognathus macropterus is a species of cyprinid fish native to China and northern Vietnam. It grows to a length of 27.5 centimetres (10.8 in) SL.
The Tokyo bitterling is a temperate freshwater fish of the carp family (Cyprinidae). Taxonomically, it belongs to the subfamily Acheilognathinae.
Rhodeus albomarginatus is a species of freshwater ray-finned fish in the genus Rhodeus. It is endemic to China, where it is found in the Lvjiang River of the Yangtze River drainage and uses the freshwater mussel Ptychorhynchus murinum as its host for spawning.
Sinorhodeus microlepis is a bitterling native to the Yangtze river in Chongqing City, China, and it is the only member of the genus Sinorhodeus. This species breeds in the Asian clam, which is different from all other bitterling-like cyprinids.
