The Serranidae are a large family of fishes belonging to the order Perciformes. The family contains about 450 species in 65 genera, including the sea basses and the groupers. Although many species are small, in some cases less than 10 cm (3.9 in), the giant grouper is one of the largest bony fishes in the world, growing to 2.7 m in length and 400 kg (880 lb) in weight. Representatives of this group live in tropical and subtropical seas worldwide.
Cyprinus is the genus of typical carps in family Cyprinidae. Most species in the genus are of East Asia origin with only the common carp in Western Asia and Europe; this invasive species has also been introduced to many other regions around the world. Cyprinus are closely related to some more barb-like genera, such as Cyclocheilichthys and Barbonymus (tinfoils). The crucian carps (Carassius) of western Eurasia, which include the goldfish, are apparently not as closely related.
Groupers are fish of any of a number of genera in the subfamily Epinephelinae of the family Serranidae, in the order Perciformes.
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.
The weasel sharks are a family, the Hemigaleidae, of ground sharks found from the eastern Atlantic Ocean to the continental Indo-Pacific. They are found in shallow coastal waters to a depth of 100 m (330 ft).
Chanodichthys is a genus of cyprinid freshwater fish, consisting of five species from eastern Asia. The name is derived from the Greek word chanos, meaning "abyss, mouth opened, inmensity", and the Greek word ichthys, meaning "fish". Chanodichthys is closely related to Culter and some species have been moved between these genera.
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".
Pseudexostoma is a genus of fish in the family Sisoridae endemic to China. These species are restricted to the upper Salween and one upper branch of the Irrawaddy in China. P. brachysoma is known only from the middle and lower Nujiang River. P. yunnanensis is only known from the upper Dayinjiang. These rivers were once connected, but are now separated. Also, the environment and temperature of the Nujiang River became greatly different between the northern and southern areas, leading to speciation.
Pangasius is a genus of medium-large to very large shark catfishes native to fresh water in South and Southeast Asia. The term "pangasius" is sometimes used to specifically refer to the commercially important basa fish, P. bocourti.
Lutjanus is a genus of marine ray-finned fish, snappers belonging to the family Lutjanidae. They are found in the Atlantic, Indian, and Pacific Oceans. They are predatory fish usually found in tropical and subtropical reefs, and mangrove forests. This genus also includes two species that only occur in fresh and brackish waters.
Lutjanidae, or snappers are a family of perciform fish, mainly marine, but with some members inhabiting estuaries, feeding in fresh water. The family includes about 113 species. Some are important food fish. One of the best known is the red snapper.
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.
Discogobio is a genus of cyprinid fish that are found in eastern Asia. So far the 16 species have only been identified from China and Vietnam wherein each species is endemic to the country in which it is found.
Hemibarbus is a genus of cyprinid fish found in eastern Asia. There are currently 12 recognized species in this genus.
Sarcocheilichthys is a genus of cyprinid fishes found in eastern Asia. There are currently 12 species in the genus.
Xenocypris yunnanensis, the Kunming nase, is a species of ray-finned fish in the genus Xenocypris. It is endemic to Lake Dianchi in Yunnan Province, China. The species started to decline in the 1970s and has not been caught in the lake after two specimens were collected in 1985; it may be extinct. Its demise is likely due to introduced fish species, grass carp. It was also impacted by over-fishing and pollution. They grow to a maximum length of 23 cm (9.1 in). They are dark grayish with a silvery white belly, gray dorsal fin, reddish anal fin and orange red caudal fin. They have a rounded belly, blunt snout, eyes on the lateral of their heads, small and transverse mouth.
Balitoropsis also known as the lizard loaches is a genus of hillstream loaches native to eastern Asia.
Xenocyprinae, is a contentious subfamily of the family Cyprinidae, the carp and minnow family, originally from eastern Asia.
Xenocypris davidi is a freshwater fish native to the Pearl River, Hainan Island, the Yangtze River, the Yellow River and the southeast coast of China. It is the subject of artisanal fishing, sport fishing, and a nascent aquaculture attempt.
