Butterfly Koi, Longfin Koi, or Dragon Carp are a type of ornamental fish notable for their elongated finnage. The fish are a breed of the common carp, Cyprinus carpio, which includes numerous wild carp races equally good equally domesticated koi ("Nishikigoi").
Butterfly Koi originated inward the mid-20th century equally a number of an endeavor to growth the hardiness of traditional koi. Japanese breeders interbred wild Indonesian Longfin river carp amongst traditional koi. The resulting fish had longer fins, long barbells, pompom nostrils, in addition to were hardier than koi. These were known inward Japan equally "onagaoi" or "hire naga koi", or translated inward English linguistic communication "long tail koi". Randy LeFever, the boy of Wyatt LeFever, a noted breeder of koi, is credited amongst suggesting they looked similar butterflies, a trait for which the breed is named. They are also sometimes referred to equally Dragon Koi.
Nishikigoi Judging

Conformation - The ideal shape of a koi has been laid upward past times tradition to move generously oval. By contrast, butterfly koi are naturally to a greater extent than slender. This deviation is amplified past times the fact that traditional koi judging is done from a top-down viewing angle.
Relationship Of Fin To Body – The ratio of fin-to-body is an of import scoring criteria inward nishikigoi competitions. By design, Longfin embody a ratio that exceeds the standards applied to nishikigoi past times 500 to 1000 percent.
Pattern Differences - Great liberate energy has been given to developing butterfly koi versions of traditional koi patterns, (eg: kohaku, sanke, showa, utsuri in addition to ogon). Butterfly koi, however, exhibit these patterns inward a slightly different way.
For these reasons, Japan’s airinkai (an scheme that sanctions Japanese nishikigoi hobbyist competitions) conduct hold disallowed butterfly koi from competitive judging for many years, although their American counterpart the American Koi Club Association (AKCA) has (as of June, 2006) reportedly created novel standards for judging butterfly koi at time to come AKCA competitions if you lot are showing thw butterfly koi demo alone females.
Popularity
Butterfly koi are strongly disliked past times many keepers of traditional koi who persuasion the breed equally inferior to koi. This polarization of traditional keepers may move the argue why some koi retailers do non sell butterfly koi, in addition to why many of Japan’s famous in addition to virtually prestigious breeders do non breed butterfly koi today. They are largely unpopular inward Europe in addition to Asia, merely are pop inward the the States where they are to a greater extent than readily available. The popularity of these fish inward the United States has earned them the nickname American Koi.Health, maintenance in addition to longevity
The mutual carp is a hardy fish, in addition to koi retain that durability. Koi are cold-water fish, merely do goodness from existence kept inward the 15-25 °C (59-77°F) range, in addition to do non react good to long, cold, wintertime temperatures; their immune systems "turn off" below 10°C. Koi ponds unremarkably conduct hold a meter or to a greater extent than of depth inward areas of the Earth that operate warm during the summer, whereas inward areas that conduct hold harsher winters, ponds by in addition to large conduct hold a minimum of 1.5 meters (4½ feet). Specific pond structure has evolved past times koi keepers intent on raising show-quality koi.
Koi's brilliant colors lay them at a severe disadvantage against predators; a white-skinned Kohaku is a visual dinner bell against the nighttime light-green of a pond. Herons, kingfishers, otters, raccoons, cats, foxes, badgers in addition to hedgehogs are all capable of emptying a pond of its fish. Influenza A virus subtype H5N1 well-designed outdoor pond volition conduct hold areas also deep for herons to stand, overhangs high plenty inward a higher identify the H2O that mammals cannot accomplish in, in addition to shade trees overhead to block the persuasion of aerial passers-by. It may examine necessary to string nets or wires inward a higher identify the surface. Influenza A virus subtype H5N1 pond unremarkably includes a pump in addition to filtration scheme to proceed the H2O clear.
Koi are an omnivorous fish, in addition to volition swallow a broad multifariousness of foods, including peas, lettuce, lemons in addition to watermelon. Koi nutrient is designed non alone to move nutritionally balanced, merely also to float in addition to thence equally to encourage them to come upward to the surface. When they are eating, it is possible to banking enterprise agree koi for parasites in addition to ulcers.
Koi volition recognize the persons feeding them in addition to assemble around them at feeding times. They tin move trained to convey nutrient from one's hand. In the winter, their digestive systems irksome nearly to a halt, in addition to they swallow real little, mayhap no to a greater extent than than nibbles of algae from the bottom. Care should move taken past times hobbyists that proper oxygenation in addition to off-gassing occurs over the wintertime months inward pocket-sized H2O ponds, in addition to thence they do non perish.
Their appetites volition non come upward dorsum until the H2O becomes warm inward the spring. When the temperature drops below 50°F (10°C), feeding, especially amongst protein, is halted or the nutrient tin spoil inward their stomachs, causing sickness in addition to death.
One famous scarlet koi, named "Hanako" (c. 1751 – July 7, 1977) was owned past times several individuals, the final of whom was MD Komei Koshihara. Hanako was supposedly 226 years sometime upon her death, based on examining i of her scales inward 1966. Koi "maximum longevity" is listed equally 47 years old.
Breeding

Like virtually fish, koi reproduce through spawning inward which a woman soul lays a vast number of eggs in addition to i or to a greater extent than males fertilize them. Nurturing the resulting offspring (referred to equally "fry") is a tricky in addition to tedious job, unremarkably done alone past times professionals. Although a koi breeder may carefully select the parents they wishing based on their desired characteristics, the resulting youngster volition nonetheless exhibit a broad arrive at of color in addition to quality.
Koi volition make thousands of offspring from a unmarried spawning. However, dissimilar cattle, purebred dogs, or to a greater extent than relevantly, goldfish, the large bulk of these offspring, fifty-fifty from the best champion-grade koi, volition non move acceptable equally nishikigoi (they conduct hold no interesting colors) or may fifty-fifty move genetically defective. These unacceptable offspring are culled at diverse stages of evolution based on the breeder's practiced optic in addition to closely guarded merchandise techniques. Culled youngster are unremarkably destroyed or used equally feeder fish (mostly used for feeding arowana due to the belief it volition elevate its color), land older culls, inside their showtime twelvemonth betwixt 3" to 6" long (also called "Tosai"), are frequently sold equally lower-grade, pond-quality koi.
The semirandomized number of the koi's reproductive procedure has both advantages in addition to disadvantages for the breeder. While it requires diligent oversight to narrow downward the favorable number the breeder wants, it also makes possible the evolution of novel varieties of koi inside relatively few generations.
In the wild
Koi conduct hold been accidentally or deliberately released into the wild inward every continent except Antarctica. They rapidly revert to the natural coloration of mutual carp inside a few generations. In many areas, they are considered an invasive species in addition to pests. They greatly growth the turbidity of the H2O because they are constantly stirring upward the substrate.This makes waterways unattractive, reduces the abundance of aquatic plants, in addition to tin homecoming the H2O unsuitable for swimming or drinking, fifty-fifty past times livestock. In some countries, koi conduct hold caused in addition to thence much impairment to waterways that vast amounts of coin in addition to endeavor conduct hold been spent trying to eradicate them, largely unsuccessfully.
