It became a tradition for married men to give their wives a goldfish on their first anniversary, as a symbol for the prosperous years to come. ĭuring the 1620s, goldfish were highly regarded in southern Europe because of their metallic scales, and symbolized good luck and fortune. In 1611, goldfish were introduced to Portugal and from there to other parts of Europe. In 1603, goldfish were introduced to Japan. The first occurrence of -tailed goldfish was recorded in the Ming dynasty. ĭuring the Ming dynasty (1368–1644), goldfish also began to be raised indoors, which permitted selection for mutations that would not be able to survive in ponds. The occurrence of other colors (apart from red and gold) was first recorded in 1276. By this time, people outside the imperial family were forbidden to keep goldfish of the gold (yellow) variety, yellow being the imperial color. In 1162, the empress of the Song dynasty ordered the construction of a pond to collect the red and gold variety. īy the Song dynasty (AD 960–1279), the selective domestic breeding of goldfish was firmly established. On special occasions at which guests were expected, they would be moved to a much smaller container for display. People began to selectively breed the gold variety instead of the silver variety, keeping them in ponds or other bodies of water. A natural genetic mutation produced gold (actually yellowish orange) rather than silver coloration. ĭuring the Tang dynasty (AD 618–907), it was popular to raise carp in ornamental ponds and water gardens. Some of these normally gray or silver species have a tendency to produce red, orange, or yellow color mutations this was first recorded in Imperial China, during the Jin dynasty (266–420). Various species of carp (collectively known as Asian carp) have been bred and reared as food fish for thousands of years in East Asia. Ryukin goldfish, Plate XIX in Goldfish and Their Culture in Japan, by Shinno suke Matsubara. An aquarium of the 1850s of the type that contained Goldfish among other coldwater species. 1080–1120) Male Prussian Carp ( Carassius gibelio) showing lots of epithelial tubercles which appear at spawning time. History Three goldfish from Fish Swimming Amid Falling Flowers, a Song dynasty painting by Liu Cai ( c. Goldfish breeds vary greatly in size, body shape, fin configuration, and coloration (various combinations of white, yellow, orange, red, brown, and black are known). It was first selectively bred for color in imperial China more than 1,000 years ago, where several distinct breeds were developed. Native to China, the goldfish is a relatively small member of the carp family (which also includes the Prussian carp and the crucian carp). Goldfish released into the wild have become an invasive pest in parts of North America. It is commonly kept as a pet in indoor aquariums, and is one of the most popular aquarium fish. The goldfish ( Carassius auratus) is a freshwater fish in the family Cyprinidae of order Cypriniformes. Carassius auratus by Alexander Francis Lydon.

Instead, she suggests calling the pet shop that sold the fish or your state department of fish and wildlife. "It's pretty simple: Don't dump your fish," she said. A type of algae that produces toxic compounds that kill off fish, Caulerpa was eradicated in 2000 (at great expense) from lagoons in Southern California.Īquarium owners should be more careful when disposing of unwanted fish and other animals, Williams cautioned. One of the nastiest is a deadly type of seaweed known as Caulerpa. The invaders include tropical fish, seaweed and snails. More than 11 million nonnative marine organisms representing at least 102 species arrive at ports in San Francisco and Los Angeles alone, Williams has found. Other ways that invasive species find their way into natural ecosystems include aquaculture, live seafood, live bait, and fishing and recreation vessels. Between 20 percent and 69 percent of fish keepers surveyed in Texas admitted to dumping, according to Williams. While the exact number of aquarium owners dumping fish is unknown, scientists know the practice is occurring because these species could not have ended up in these waters naturally.
