Channa is a genus of predatory fish in the family Channidae, commonly known as snakeheads, native to freshwater habitats in Asia. This genus contains about 50 scientifically described species. The genus has a wide natural distribution extending from Iraq in the west, to Indonesia and China in the east, and parts of Siberia in the Far East. A particularly high richness of species exists in Myanmar (Burma) and northeastern India, and many Channa species live nowhere else. In contrast, a few widespread species have been introduced to several regions outside their natural range, where they often become invasive. The large and medium-sized Channa species are among the most common staple food fish in several Asian countries, and they are extensively cultured. Apart from their importance as a food fish, snakeheads are consumed in some regions as a traditional medicine for wound healing and reducing postoperative pain and discomfort, and collected for the international aquarium pet trade.
Eleotridae is a family of fish commonly known as sleeper gobies, with about 34 genera and 180 species. Most species are found in the tropical Indo-Pacific region, but there are also species in subtropical and temperate regions, warmer parts of the Americas and near the Atlantic coast in Africa. While many eleotrids pass through a planktonic stage in the sea and some spend their entire lives in the sea; as adults, the majority live in freshwater streams and brackish water. One of its genera, Caecieleotris, is troglobitic. They are especially important as predators in the freshwater stream ecosystems on oceanic islands such as New Zealand and Hawaii that otherwise lack the predatory fish families typical of nearby continents, such as catfish. Anatomically, they are similar to the gobies (Gobiidae), though unlike the majority of gobies, they do not have a pelvic sucker.
Rasbora is a genus of fish in the family Cyprinidae. They are native to freshwater habitats in South and Southeast Asia, as well as southeast China. A single species, R. gerlachi, is only known from an old specimen that reputedly originated from Africa (Cameroon), but this locality is considered doubtful. They are small, up to 17 cm (6.7 in) long, although most species do not surpass 10 cm (4 in) and many have a dark horizontal stripe.
Pomacentrus is a genus of marine damselfish in the family Pomacentridae. These fish inhabit tropical locations and are often captured or bred as aquarium fish.
Stiphodon is a genus of freshwater gobies. They inhabit swift, clear streams close to the sea and are found in large parts of Asia and Oceania. Many of the 36 currently recognized species have extremely restricted distributions on single islands or even single streams. These are small gobies with bodies squarish in cross section. A female of Stiphodon multisquamus with a standard length of 60.4mm is the largest Stiphodon individual on record. Males of Stiphodon species are often vividly colored and a few species are occasionally sold in the aquarium trade, including Stiphodon ornatus, Stiphodon atropurpureus, Stiphodon maculidorsalis, Stiphodon semoni, and Stiphodon surrufus.
Schismatogobius is a genus of fish in the subfamily Gobionellinae. They are native to southern and eastern Asia, Australia and the Pacific Islands. Adults dwell in freshwater habitat such as streams and rivers, where they live along the sand and gravel substrates.
Awaous is a genus of fish in the family Gobiidae, the gobies. They are native to fresh, marine and brackish waters from Africa to the Americas.
Lentipes is a genus of gobies in the family Oxudercidae, native to fresh, marine and brackish waters of the Malay Archipelago and islands in the Pacific. Its species are typically from fast-flowing streams and some are anadromous.
Oxyeleotris is a genus of sleeper gobies mostly restricted to Australia and New Guinea, though some are found in Southeast Asia.
Redigobius is a genus of fish in the goby family, Oxudercidae, known commonly as dualspot gobies. They are native to the western Indo-Pacific region, where they occur in estuaries and freshwater habitats just above the tidal influence.
Sicyopterus is a genus of gobies native fresh waters from Madagascar to the Pacific islands.
The Gobionellinae are a subfamily of fish which was formerly classified in the family Gobiidae, the gobies, but the 5th Edition of Fishes of the World classifies the subfamily as part of the family Oxudercidae. Members of Gobionellinae mostly inhabit estuarine and freshwater habitats; the main exception is the genus Gnatholepis, which live with corals in marine environments. The subfamily is distributed in tropical and temperate regions around the world with the exception of the northeastern Atlantic Ocean, the Mediterranean Sea, and the Ponto-Caspian region. It includes around 370 species and 55 genera: Wikipedia articles about genera list about 389 species.
The Sicydiinae are a small subfamily of freshwater gobies, with only nine genera. They are usually found in fast-moving mountain streams in tropical islands. They are characterized by highly developed rounded suction discs and an amphidromous lifecycle. Adult lengths range from 2 to 15 cm. Some species are popular in the aquarium trade. The genera included under Sicydiinae are:
Eleotris is a genus of fish in the family Eleotridae with a circumglobal distribution in tropical and subtropical regions.
Callogobius is a genus of fish in the family Gobiidae found in brackish and marine waters of the Indian and Pacific Ocean.
Gnatholepis is a genus of fish in the family Gobiidae, the gobies. It is the only marine genus in the subfamily Gobionellinae, which otherwise includes mostly estuary-dwelling and freshwater fish. Gnatholepis are tropical fish associated with sandy habitat around corals.
The Malabar goby, Stenogobius gymnopomus is a species of goby endemic to the Indo-Pacific regional countries such as India, Somalia, Indonesia, Andaman Islands. where it can be found in marine, brackish and fresh waters. The habitats include coastal waters, estuaries and tidal zone of rivers. This species can reach a length of 15.0 centimetres (5.9 in) SL. It feeds mainly on cladocerans, as well as fish eggs and scales. This species is a batch spawner which has a prolonged spawning season, extending from August to December in Kerala. The female's fecundity was between 46,323 and 61,291 eggs while the sex ratios favours males in local populations.
Knowledge and Management of Aquatic Ecosystems is a peer-reviewed open access scientific journal covering management and conservation issues related to freshwater ecosystems. The journal publishes articles, short communications, reviews, comments and replies. It is published by EDP Sciences and the editor-in-chief is Thierry Oberdorff (IRD). The journal was established in 1928 as Bulletin Français de la Pêche et de la Pisciculture and obtained its current title in 2008.
Stenogobius ophthalmoporus, is a species of goby native to Japan, Taiwan, Viet Nam, Philippines and Indonesia. Males of this species can reach a length of 14.2 centimetres (5.6 in) SL.
