Carassius auratus by Alexander Francis Lydon. The goldfish (Carassius auratus) is a freshwater fish in the family Cyprinidae of order Cypriniformes. It is commonly kept as a pet in indoor aquariums, and is one of the most popular aquarium fish. Goldfish released into the wild have become an invasive pest in parts of North America. Carassius auratus (Linnaeus, 1758) Common name: Goldfish. Taxonomy: available through. Identification: Carassius auratus has an elongated, stocky body. Not all individuals have the well-known bright gold color. Wild populations vary in color from gold to olive green or even creamy white. It possesses a long dorsal fin with 15 to 21 rays and a.

Carassius auratus auratus has been bred and raised for over 500 years. It was introduced into Japan and Europe in the fifteenth and eighteenth centuries, respectively. C. auratus auratus is an attractive aquaculture candidate for the aquarium trade and is extremely valuable commercially. In addition, it is commonly used as baitfish, as live. There are many breeds of goldfish (Carassius auratus). This is a celestial eye goldfish, which has large eyes turned upward. This is a celestial eye goldfish, which has large eyes turned upward. Goldfish belong to the Cyprinidae family and the Carassius genus, and the scientific name is Carassius auratus.Carassius is derived from the Latin word karass, which is a name for the fish.Auratus means "gilded.". Biologists used to believe the goldfish was a subspecies of the crucian or Prussian carp, but it is now believed to be its own species. Identification: Carassius auratus has an elongated, stocky body. Not all individuals have the well-known bright gold color. Wild populations vary in color from gold to olive green or even creamy white. It possesses a long dorsal fin with 15 to 21 rays and a hard serrate spine at the origin of the dorsal and anal fins.

Geographic Range. Goldfish (Carassius auratus) originated in eastern Asia including China, Hong Kong, Korea, and Taiwan.From China, the range of this species expanded north to most of the world. Goldfish have been introduced in the United States in Kansas, the northern part of Oklahoma, Washington, New Mexico, and four of the five Great Lakes: Lake Erie, Lake Michigan, Lake Huron, and Lake. Teleostei (teleosts) > Cypriniformes (Carps) > Cyprinidae (Minnows or carps) > Cyprininae Etymology: Carassius: Latinization of , karass, karausche, European crucian carp (Ref. 45335); auratus: From the words carassius--Latin of karass (common name for these fishes in Eurasia) and auratus, meaning gilded (Ref. 10294). More on author: Linnaeus. Carassius auratus. What do they look like? As there are over a hundred varieties of goldfish, coloration and physical characteristics vary greatly. The common goldfish has two sets of paired fins - the pectoral fins and pelvic fins, and three single fins- the dorsal, caudal, and anal fin. The head lacks scales. Goldfish (Carassius auratus), historically considered as an ornamental species, is widely used as an important model organism for a wide variety of research applications, including biomedical research.For instance, it has proven a suitable model for studies on endocrinology, reproduction, and neurology. Studies on cardiac function and gut motility are other examples of biomedical research.

Introduction. Since 1901, when Underwood first described the role of the goldfish Carassius auratus in destroying mosquito larvae, the use of this teleost in research considerably increased over the years.It now represents a largely used model organism in endocrinology (Blanco et al. 2018), cell biology (Choresca et al. 2009), immunology (Hanington et al. 2006), neurobiology (Portavella et al. To examine the phylogeographical pattern of the widely distributed genus Carassius across Eurasia and investigate the possible homoploid hybrid origin of the Carassius auratus complex lineage in light of past climatic events, the mitochondrial genome (mtDNA) and one nuclear DNA were used to reconstruct the phylogenetic relationship between the.
The use of unconventional model organisms is significantly increasing in different fields of research, widely contributing to advance life sciences understanding. Among fishes, the cyprinid Carassius auratus (goldfish) is largely used for studies on comparative and evolutionary endocrinology, neurobiology, adaptive and conservation physiology, as well as for translational research aimed to. Goldfish (Carassius auratus) were domesticated in ancient China from crucian carp (both are still considered the same species) (1-3), which is one of the most important farmed fish, with global aquaculture production of 3.096 million tons of crucian carp in 2018 ().The appearance of red scales on normally gray or silver crucian carp was first recorded during the Chinese Jin Dynasty (AD 265.

Carassius auratus auratus (Linnaeus, 1758)
Scientific Name: Carassius auratus auratus; Social Grouping: Groups - Can be kept singly or in groups. IUCN Red List: NE - Not Evaluated or not listed; Description. The Common Goldfish is an elongated, flat-bodied variety of goldfish. The head is wide but short and its body tapers smoothly from its back and belly to the base of its caudal. Carassius auratus is a primary freshwater fish with bisexual diploid and unisexual gynogenetic triploid lineages. It is distributed widely in Eurasia and is especially common in East Asia. Although several genetic studies have been conducted on C. auratus, they have not provided clear phylogenetic and evolutionary descriptions of this fish, probably due to selection bias in sampling sites and.
