The ricefishes are a family (Adrianichthyidae) of small ray-finned fish that are found in fresh and brackish waters from India to Japan and out into the Malay Archipelago, most notably Sulawesi. The common name ricefish derives from the fact that some species are found in rice paddies. This family consists of about 37 species in two genera. Several species are rare and threatened, and some 2–4 may already be extinct.
Lake Poso is a lake in Central Sulawesi, Indonesia, and the third-deepest lake in Indonesia.
Adrianichthys kruyti is a critically endangered species of ricefish that is endemic to Lake Poso, Sulawesi, Indonesia. It was discovered by Max Wilhelm Carl Weber on his Siboga Expedition to Indonesia.
Nomorhamphus weberi is a species of viviparous halfbeak endemic to Lake Matano in Sulawesi, Indonesia. This species can reach a length of 7.5 centimetres (3.0 in) SL. The specific name honours the Dutch ichthyologist Max Carl Wilhelm Weber (1852-1937).
Oryzias is a genus of ricefishes native to fresh and brackish water in east and south Asia. Some species are widespread and the Japanese rice fish is commonly used in science as a model organism, while others have very small ranges and are threatened. They are small, up to 8 cm (3.1 in) long, and most are relatively plain in colour.
Paratherina wolterecki is a species of fish in the subfamily Telmatherininae, part of the rainbowfish family Melanotaeniidae. This species is endemic to Lakes Towuti and Mahalona on the Indonesian island of Sulawesi. It reaches up to 15 cm (5.9 in) in total length. Their environment is pelagic and they live in tropical climates. It has the characteristic of having a mouth pointed upward. The specific name honours the hydrologist and biologist Richard Woltereck (1877-1944), who collected specimens of all four species in the genus Paratherina and who sketched them from life.
Mugilogobius sarasinorum, Sarasin's goby, is a species of goby endemic to Lake Poso in Sulawesi, Indonesia. This species can reach a length of 8 centimetres (3.1 in) TL. It is important to local commercial fisheries and the fishing community.
Telmatherina abendanoni is a species of fish in the subfamily Telmatherininae part of the family Melanotaeniidae, the rainbowfishes. It is endemic to Indonesia where it occurs only in Lake Matano on the island of Sulawesi. The specific name honours the Dutch malacologist and mining engineer Eduard Cornelius Abendanon (1878-1962), who was the leader of the Central Celebes Expedition of 1907–1918, on which the type was collected.
Telmatherina antoniae is a species of fish in the subfamily Telmatherininae part of the family Melanotaeniidae, the rainbowfishes. It is endemic to Indonesia where it occurs only in Lake Matano on Sulawesi. The species was described in 1991 by Maurice Kottelat and its specific name honours his wife, Antonia.
Telmatherina sarasinorum is a species of fish in the subfamily Telmatherininae part of the family Melanotaeniidae, the rainbowfishes. It is endemic to Indonesia, where it occurs only in Lake Matano on the island of Sulawesi. This species was described in 1991 by Maurice Kottelat, the types being collected at Mengonuwai on Lake Matano. Kottelat gave the species the specific name sarasinorum in honour of the Swiss second cousins, naturalists and ethnographers Paul (1856-1929) and Fritz Sarasin (1859-1942). The Sarasins discovered Lake Matano and collected the first specimens of fishes in the genus Telmatherina.
Telmatherina wahjui is a species of fish in the subfamily Telmatherininae, which is part of the family Melanotaeniidae; the rainbowfishes. It is endemic to Indonesia, where it occurs only in Lake Matano on the island of Sulawesi. It can reach a maximum length of around 5 centimetres (2.0 in). This species was described in 1991 by Mairice Kottelat with a type locality of Alaponkepi which is situated at the outlet of Lake Matano. The specific name honours Beni N. Wahju who was Vice President and Secretary of P. T. Inco Industries. Mr Wahju's support was vital in ensuring that the ichthyological survey of the Malili Lakes, in which the type of this species was collected, was possible.
Tondanichthys kottelati is a species of viviparous halfbeak endemic to Indonesia, where it is only known from Lake Tondano near Mount Tondano in the far north of the island of Sulawesi. It grows to a length of 6.4 centimetres (2.5 in) SL. Despite being a member of the viviparous halfbeak family, this species is believed to be oviparous. This species was described in 1995 by Bruce Baden Collette and its species name honours the Swiss ichthyologist Maurice Kottelat.
The egg-carrying buntingi is a species of fish in the family Adrianichthyidae. It is endemic to Lake Poso in Sulawesi, Indonesia.
Popta's buntingi is a endangered species of fish in the family Adrianichthyidae. It is endemic to Lake Poso in Sulawesi, Indonesia. This species was described by Max Carl Wilhelm Weber and Lieven Ferdinand de Beaufort in 1922 and they gave it the species name poptae in honour of their fellow Dutch ichthyologist Canna Maria Louise Popta (1860-1929).
Oryzias sarasinorum, the Sarasins minnow or Sarasins buntingi, is a species of ricefish in the Adrianichthyidae. It is endemic to Lake Lindu in Lore Lindu National Park, Sulawesi, Indonesia. This species was described as Haplochilus sarasinorum by C.M.L. Popta in 1905 and she named it in honour of the Swiss naturalists and second cousins Paul Sarasin (1856-1929) and Fritz Sarasin (1859-1942), the latter being the collector of the type. Although the IUCN state that the population of this fish is stabled it is threatened by introduced non native fish, common carp, Mozambique tilapia and walking catfish; and a decline in water quality caused by increased agriculture in the lake's catchment which is causing a decline in water quality, it is therefore assessed as Critically Endangered.
Allen's river garfish is a species of viviparous halfbeak endemic to West Papua in Indonesia.
Adrianichthys is a genus of ricefishes. The genus is endemic to Lake Poso in Sulawesi, Indonesia. All four species are considered seriously threatened and two of these, A. kruyti and A. roseni, have not been recorded for decades, leading to fears that they already are extinct. Adrianichthys are larger than the Oryzias ricefish, reaching lengths of 8.5–17.1 cm (3.3–6.7 in) depending on the exact species involved. The name of this genus is a compound ending in the Greek ichthys for "fish" with the first part honouring the linguist and missionary Nicolaus Adriani (1865-1926), who collected specimens around Lake Poso.
The American halfbeak, also known as Meek's halfbeak, is a halfbeak from the family Hemiramphidae.
Pristolepis grootii, commonly known as the Indonesian leaffish, is a fish native to streams of the Indonesian islands of Sumatra, Bangka, Belitung and Borneo, and Thailand. It is part of the first Western Indonesian and Sulawesi Freshwater fish species recorded by December 31, 1991 along with another 963 species. Further research lead to the discovery of other 79 fish species in the area. By May 31st, 1996 deletions and additions were made revealing a grand total of 1032 known fish species in the area. The specific name honours the Dutch naturalist and ethnographer Cornelis de Groot van Embden (1817-1896).
Donn Eric Rosen (1929-1986) was a member of the staff of the American Museum of Natural History. He was a Distinguished Fellow of the American Society of Ichthyologists and Herpetologists.
