A dace is a small fish that can be one of many different species. The unmodified name is usually a reference to the common dace. This, like most fish called "daces", belongs to the family Cyprinidae, mostly in subfamily Leuciscinae.
The common dace is a species of freshwater and brackish water ray-finned fish from the family Cyprinidae which is native to Europe but which has been introduced to other parts of the world. It is a quarry species for coarse anglers.
Leuciscus is a genus of fish belonging to the family Cyprinidae. They are inland water fishes commonly called Eurasian daces. The genus is widespread from Europe to Siberia. Species broadly distributed in Europe include the common dace Leuciscus leuciscus and the ide L. idus.
Rhinichthys, known as the riffle daces, is a genus of freshwater fish in the carp family (Cyprinidae) of the order Cypriniformes. The type species is Rhinichthys atratulus, the blacknose dace. Rhinichthys species range throughout North America.
Nettastomatidae, the duckbill eels or witch eels are a family of eels. The name is from νῆττα and στόμα.
Leptocephalus is a genus that was used for species of larval eels, called leptocephali, that were thought to be new fish species, or whose adult eel species were not known. Leptocephali differ so much in appearance from their adults that the larvae and adults of eels are not easily matched, and when first discovered, leptocephali were thought to be a distinct type of fishes, but not eels. Because of this, the genus designation of Leptocephalus was used for a while for unidentified leptocephali even after it was known that these were the larvae of eels thus becoming a "wastebasket taxon", but this practice is no longer used. Examples of marine congrid larvae, found in the western Indian Ocean and the Red Sea that were named this way are listed below. Only two species in two families are currently treated as having any validity, though the validity of L. bellottii is strongly in doubt.
Pterothrissus gissu, also known as the Japanese gissu, is a species of ray-finned fish in the family Albulidae. The Japanese gissu is a rare fish that is distributed in deep water off northwest Pacific Ocean. This fish is known to pass through a leptocephalus larval stage, but only metamorphosed specimens have been available. This species is the only member of its genus.
Pseudobarbus is a ray-finned fish genus in the family Cyprinidae. The type species is Burchell's redfin. The scientific name is derived from the Ancient Greek pseudes ("false") and the Latin word barbus. This genus contains some of the South African redfins. It was originally proposed as a subgenus, but has since been found worthy of recognition as a full genus.
The predatory carp, also known as the redfin culter or skygazer, is a species of ray-finned fish in the genus Chanodichthys. This East Asian freshwater cyprinid ranges from the Amur River south to Taiwan and the Red River, as well as Lake Buir in Mongolia. It reaches 102 cm in length and 9 kg in weight.
Leuciscinae is a subfamily of the freshwater fish family Cyprinidae, which contains the true minnows.
The redfin shiner is a freshwater fish in the family Cyprinidae. The redfin shiner is most commonly found in the Ohio and Mississippi River basins, as well as in drainages of the Great Lakes. The diet of the redfin shiner consists mostly of algae and small insects. This species prefers calm water in low-gradient streams over substrates of gravel or sand with some vegetation.
Pseudaspius leptocephalus, the redfin, is a species of cyprinid fish found in eastern Asia where it occurs in the countries of Russia, Mongolia and China.
The redfin pickerel is a subspecies of freshwater fish belonging to the pike family (Esocidae) of the order Esociformes. Not to be confused with its close relatives, the grass pickerel and the chain pickerel, this fish is unique in the fact that it has brightly colored red fins. Like all pikes, the redfin pickerel is an ambush predator, lying amongst thick vegetation in wait for smaller, more agile prey to enter within its range of attack.
The big-scaled redfin, also known as the Japanese dace and ugui, is a medium-sized Asian fish. First described by Albert Günther in 1877 as Leuciscus hakonensis, it was the type specimen of the genus Tribolodon, having been described again as Tribolodon punctatum by Henri Émile Sauvage when he established that genus in 1883. It is the most widely distributed of the Pseudaspius species, found over much of the Sea of Japan. It is known to carry a number of parasites, including the trematode species Centrocestus armatus, and the copepod species Ergasilus fidiformis, which is carried in the fish's gills.
Pseudaspius nakamurai is a species of fish in the family Cyprinidae. It is endemic to Japan.
Pseudaspius sachalinensis is a species of fish in the family Cyprinidae. It is endemic to Japan and Sakhalin.
Sedercypris, commonly known as Cedarberg redfins, is a genus of fish in the family Cyprinidae endemic to the Clanwilliam Olifants River system in South Africa.
