Goldfish Carassius auratus Class: Actinopterygii Order: Cypriniformes Family: Cyprinidae Characteristics: There are many different varieties of goldfish that vary greatly in color and appearance. Common, wild goldfish range in color from orange to olive green to milky white. These goldfish have a general fin pattern that is two sets of paired fins - the pectoral fins and pelvic fins, and three single fins- the dorsal, caudal, and anal fin. Goldfish can grow to be 1.5 feet long, but are usually smaller. They have large eyes and no scales on the head. (Animal Range & Habitat: Diversity) Native to Eastern Asia, including China and adjacent Behavior: Goldfish are somewhat social fish and tend to school with regions. Goldfish can now be other fish of similar size. They live well with other varieties of found almost everywhere there goldfish and different fish species. Goldfish are very common as pets is fresh water. Goldfish are and ornamental pond fish. If properly cared for, they do well in mostly kept as pets in these environments. Goldfish are also commonly used in research. aquariums or small ponds. Reproduction: Females will spawn multiple times during the breeding period. The eggs are sticky and will hold on underwater vegetation for development. The juveniles need high temperatures to grow properly (Fishbase). Goldfish can hybridize with common carp and in some places the hybrids outnumber the pure goldfish. (blue:native red:introduced) Diet: Wild: Goldfish are opportunistic feeders and will feed on most Lifespan: up to 25 years in captivity, 6-7 years in the wild. available items like crustaceans, insects, and various plant matter. Zoo: Pelleted fish food Special Adaptations: Goldfish were domesticated from carp Conservation: IUCN evaluated the goldfish as least concern. more than a thousand years ago in Goldfish can be found most places that fresh water exists. The China. Goldfish are smaller and species has been introduced worldwide. In the USA, goldfish in the more colorful than common carp. wild are considered a pest species. (USGS) IUCN Conservation Status: FYI: Least Concern - Goldfish have a good memory and can even recognize faces and voices of its owners. -They can be trained to swim through hoops and play soccer. .

This work is licensed under the Creative Commons Attribution International License (CC BY). http://creativecommons.org/licenses/by/4.0/ Abstract Mitochondrial DNA fragment of cytb was compared in all species Carassius auratus complex and three forms of ornamental goldfish. It is shown that the phylogenetic relationships between com- plex species correspond to the existing views, based on mtDNA data and geographical distribution. All forms of ornamental goldfish have a monophyletic origin from Chinese goldfish C. auratus au- ratus. The analysis showed that three nuclear genes (rps7, GH1 and Rh) in the two forms of orna- mental goldfish (Oriental twintail goldfish and Chinese Ranchu) were almost identical C. auratus auratus genes, while all three gene in another more simple form of goldfish (common goldfish) were highly homologous to carp Cyprinus carpio nuclear genes. The obtained data suggested that in the history of aquarium goldfish breeding occurred the stage of distant hybridization between goldfish and common carp. Subsequently, the nuclear genomes of some ornamental forms could be enriched by goldfish genes (a relatively recent form as Oriental twintail goldfish and Chinese Ranchu) or common carp genes (the simplest and most ancient forms like common goldfish) as a result of multidirectional breeding and selection of aquarium goldfish various forms.

There are no native cyprinids in Australia. A number of cyprinids have been widely introduced to other parts of the world with four species in four genera which have been introduced to Australia. There are two species found in the ACT and surrounding area, Carp and Goldfish. Common Name: Goldfish Scientific Name: Carassius auratus Linnaeus 1758 Other Common Names: Common Carp, Crucian Carp, Prussian Carp, Other Scientific Names: None Usual wild colour. Photo: N. Armstrong Biology and Habitat Goldfish are usually associated with warm, slow-flowing lowland rivers or lakes. They are often found in association with aquatic vegetation. Goldfish spawn during summer with fish maturing at 100–150 mm length. Eggs are laid amongst aquatic plants and hatch in about one week. The diet includes small crustaceans, aquatic insect larvae, plant material and detritus. Goldfish in the Canberra region are often heavily infected with the parasitic copepod Lernaea sp. A consignment of Goldfish from Japan to Victoria is believed to be responsible for introducing to Australia the disease ‘Goldfish ulcer’, which also affects salmonid species such as trout. Apart from the introduction of this disease, the species is generally regarded as a ‘benign’ introduction to Australia, with little or no adverse impacts documented. 60 Fish in the Upper Murrumbidgee Catchment: A Review of Current Knowledge SOF text final l/out 12/12/02 12:16 PM Page 61 Distribution, Abundance and Evidence of Change Goldfish are native to eastern Asia and were first introduced into Australia in the 1860s when it was imported as an ornamental fish.

AQUATIC INVADERS a Sea Grant/AZA Partnership 1 Goldfish Carassius Auratus • Make Sure That in the Event of a Flood, the Fish, Plants, Snails, Etc
U.S. Geological Survey COMMON NAME: Goldfish SCIENTIFIC NAME: Carassius auratus (Linnaeus 1758) NATIVE DISTRIBUTION: Eastern and central Asia, including China, Russia, Korea, and possibly Japan and Taiwan. U.S. distribution: The goldfish was the first foreign fish introduced into the U. S., and has been here since at least the late 1600s. The species can be found in the wild in every state except Alaska. Habitat: The goldfish is a very adaptable species, and lives in a variety of natural and artificial habitats, Survey Geological U.S. including: lakes, ponds, reservoirs and slow-flowing streams. It is often found in areas with submerged aquatic vegetation. Life cycle: Individuals become adults after about 1 to 2 years. During spawning, the females scatter their adhesive eggs over vegetation, roots, gravel or other sub- strata. The males then fertilize the eggs. Eggs hatch in about 3 to 7 days. Individuals typically live 6 to 7 years. Cool facts: In the wild, the species is a dull olive-brown or bronze. The bright orange goldfish we are familiar with from pet stores is actually a mutation that has been selectively bred for by fish grow- ers. When re-introduced to the wild, reproducing populations of bright orange goldfish quickly revert to the ancestral “wild” type coloration within a few generations. Pathways of invasion: Aquarium releases, bait bucket releases, water garden flooding. Impacts: Goldfish are messy eaters, stirring up the substrate while feeding. This suspension of silt causes excess turbidity in the water, which in turn can kill many kinds of aquatic plants. Additionally, suspended silt can cover the eggs of native species of fish and kill them.

Species Composition and Invasion Risks of Alien Ornamental Freshwater
www.nature.com/scientificreports OPEN Species composition and invasion risks of alien ornamental freshwater fshes from pet stores in Klang Valley, Malaysia Abdulwakil Olawale Saba1,2, Ahmad Ismail1, Syaizwan Zahmir Zulkifi1, Muhammad Rasul Abdullah Halim3, Noor Azrizal Abdul Wahid4 & Mohammad Noor Azmai Amal1* The ornamental fsh trade has been considered as one of the most important routes of invasive alien fsh introduction into native freshwater ecosystems. Therefore, the species composition and invasion risks of fsh species from 60 freshwater fsh pet stores in Klang Valley, Malaysia were studied. A checklist of taxa belonging to 18 orders, 53 families, and 251 species of alien fshes was documented. Fish Invasiveness Screening Test (FIST) showed that seven (30.43%), eight (34.78%) and eight (34.78%) species were considered to be high, medium and low invasion risks, respectively. After the calibration of the Fish Invasiveness Screening Kit (FISK) v2 using the Receiver Operating Characteristics, a threshold value of 17 for distinguishing between invasive and non-invasive fshes was identifed. As a result, nine species (39.13%) were of high invasion risk. In this study, we found that non-native fshes dominated (85.66%) the freshwater ornamental trade in Klang Valley, while FISK is a more robust tool in assessing the risk of invasion, and for the most part, its outcome was commensurate with FIST. This study, for the frst time, revealed the number of high-risk ornamental fsh species that give an awareness of possible future invasion if unmonitored in Klang Valley, Malaysia. As a global hobby, fshkeeping is cherished by both young and old people.

Family - Cyprinidae
Family - Cyprinidae One of the largest families of fish. Found in a huge range in temperate and tropical waters of Europe, Africa, Asia, and North America. This family is characterised by no jaw teeth, mouth barbels, no adipose fin. Most closely related to the native families Ariidae and Plotosidae. Various sorts of carp are the best known, but the family also includes minnows, daces, and bitterlings. Four species have established self-maintaing populations in Australia since their introduction in1862. Being small and brightly coloured many species of cyprinids are popular with aquarists, and some valuable economically. Goldfish Carassius auratus Linnaeus (R.M McDowall) Other names: Carp, Crucian carp, Prussian carp. Description: A small, plump, deep-bodied fish, with a large blunt head. Small, toothless protusible mouth and moderately large eyes. Dorsal fin (III-IV, 14- 20); Anal fin small (II-III, 5-7). Tail moderately forked. Pelvic fins 7rays; pectorals with 16-18 rays; many long gill rakers (40-46); vertebrae 27-28. Commonly grows to 100-200 mm, can reach up to 400 mm and 1 kg. Distribution: Possiblly one of the most widespread of the exotic species introduced to Australia. Appears in most freshwater systems in the southern half of Australia, extending from the Fitzroy River in Queensland, throughout New South Wales, Victoria, and South Australia in the inland Murry-Darling system and Cooper Creek, to the south-west of Western Australia. Natural History: Is originally a native to eastern Asia, but now has almost worldwide range. Was imported to Australia in 1876 as an ornamental fish.
