Oryzias profundicola, the yellow-finned ricefish, is a species of fish in the family Adrianichthyidae.
Oryzias profundicola is endemic to Lake Towuti in Sulawesi, Indonesia. This species is known to be found within a freshwater environment and located in a benthopelagic range. They are native to a tropical climate. This species can be found in the Malili Lakes system on Sulawesi. [1] The average length of Oryzias profundicola as an unsexed male is about 5.0 centimeters or 2.3 inches. [2] [3] Oryzias profundicola is recorded to prefer to live on shores that are sloped slightly. These shores usually include boulders on sandy or pebbly bottoms. They live together is groups of 2 to 20 individuals. They are only found below the range of 1.5 meters. This species is a non-annual breeder. [4] This species is identified as vulnerable to becoming an endangered species. There is no data or information that states the main factors of the population decline that lead to the evaluation that this species is vulnerable. [1] The commonly accepted English name for this species is the Yellow Finned Ricefish [5] .
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.
The northern redbelly dace is a fresh water cyprinid fish, generally found in lakes and small streams in the northeastern United States and eastern Canada. Ranging from 1–3 inches, it is one of forty-four species from the minnow and carp family of Cyprinidae in these areas.
The Japanese rice fish, also known as the medaka, is a member of genus Oryzias (ricefish), the only genus in the subfamily Oryziinae. This small native of Japan is a denizen of rice paddies, marshes, ponds, slow-moving streams and tide pools. It is euryhaline, occurring in both brackish and freshwater. It became popular as an aquarium fish because of its hardiness and pleasant coloration: its coloration varies from creamy-white to yellowish in the wild to white, creamy-yellow, or orange in aquarium-bred individuals. Bright yellow, red or green transgenic populations, similar to GloFish, have also been developed, but are banned from sale in the EU. The medaka has been a popular pet since the 17th century in Japan. After fertilization, the female carries her eggs attached anterior to the anal fin for a period before depositing them on plants or similar things.
Lake Poso is a lake in Central Sulawesi, Indonesia, and the third-deepest lake in Indonesia.
Lake Towuti is a lake in East Luwu Regency, South Sulawesi province, Indonesia. Surrounded by mountains, it is the largest lake of the island of Sulawesi and one of the five lakes of the Malili Lake system. The Larona River flows from the lake to the Boni Bay. The town Laronda is located on its shore.
Oryzias celebensis, the Celebes medaka, fish in the family Adrianichthyidae. It is endemic to rivers, streams and lakes on the Indonesian island of Sulawesi and one river in East Timor.
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.
Oryzias marmoratus, also known as the marmorated ricefish or marmorated medaka, is a species of fish in the family Adrianichthyidae, from Lake Towuti, Lake Mahalona, Lake Lontoa and associated streams in Sulawesi, Indonesia.
Oryzias matanensis, the Matano ricefish, is a species of fish in the family Adrianichthyidae. It is endemic to Lake Matano in Sulawesi, Indonesia.
The black buntingi is a species of fish in the family Adrianichthyidae. It is endemic to Lake Poso in Sulawesi, Indonesia, here it is a pelagic species found over sand and pebble substrates.
The sharp-jawed buntingi is a species of ricefish in the family Adrianichthyidae. It is endemic to Lake Poso in Sulawesi, Indonesia.
The egg-carrying buntingi is a species of fish in the family Adrianichthyidae. It is endemic to Lake Poso in Sulawesi, Indonesia.
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.
Oryzias mekongensis is a species of fish in the family Adrianichthyidae. It is endemic to the Mekong River Basin in southeast Asia, where it is found in ditches, canals and ponds.
Oryzias javanicus, the Javan ricefish or Javanese ricefish, is a small species of fish in the family Adrianichthyidae. It lives in Peninsular Thailand, Peninsular Malaysia, Singapore, and Indonesia, where it can be seen in both brackish and fresh water in ponds, ditches, mangrove, swamps, streams and canals.
Oryzias curvinotus, or the Hainan medaka, is a species of ricefish which is found in Quang Ninh Province in northern Vietnam and Hainan, Guangdong and Hong Kong in southern China. It is found in both fresh and brackish water. This species was described as Aplocheilus curvinotus in 1927 by J.T. Nichols and C.H. Pope with the type locality given as Nodoa, Hainan Island, China.
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.
Oryzias dancena or the Indian ricefish are a freshwater–brackish fish species native to the India, Bangladesh, Sri Lanka, Myanmar and Thailand. Their maximum length is only 3.1 centimetres (1.2 in). They are normally found in brackish habitats near the coast, but it lives in fresh water as well. It is not considered threatened. This species was described as Cyprinus dancena by Francis Buchanan-Hamilton in 1822 with the type locality given as "Estuary below Calcutta".
Oryzias carnaticus or the spotted ricefish are a freshwater–brackish fish species native to the India, Bangladesh, Sri Lanka, and Myanmar. Their maximum length is only 3.0 centimetres (1.2 in). They are normally found near the coast, and can live in fresh water and brackish water.
Oryzias melastigma is a species of ricefish in the family Adrianichthyidae. This killifish was described by Sir John McLelland in 1839. It is listed as Least Concern on the IUCN Red List.
