KOI


Origins.
They are believed to have originated from Eastern Asia. Earliest records of Koi have been found in China and have been widely spread in Korea and Japan. The ornamental cultivation of carp flourished under the Chinese Qing Dynasty, Korean Silla Dynasty, and Japanese Edo Period. They are very closely related to goldfish and, in fact, the style of breeding and ornamentation has become very similar, probably through the efforts of Japanese breeders to emulate goldfish.
Etymology
The word "koi" comes from the Japanese, simply meaning "carp." It includes both the dull grey fish and the brightly colored varieties. A homophone of koi means "love, affection" and koi are therefore symbols of love and friendship in Japan: a good example is the short story Koi-san by Mukoda Kuniko.
History
While a 4th century Chinese book of the Western Jin Dynasty mentions carp with various colors, koi breeding first became popular in the 19th century in the Niigata prefecture of Japan. Farmers working the rice fields would notice that some carp were more brightly colored than others, capture them, and raise them. By the 20th century, a number of color patterns had been established, most notably the red-and-white Kohaku. The outside world did not become aware of the degree of development until 1914, when the Niigata koi were exhibited in the annual exposition in Tokyo. At that point, interest in koi exploded throughout Japan. The hobby of keeping koi spread worldwide after plastic bags and shipping of koi became both fast and safe for the fish. These factors enabled koi to be shipped worldwide with low mortality rates. Koi are now commonly sold in most pet stores, with higher-quality fish available from specialist dealers.
Koi varieties are distinguished by coloration, patterning, and scalation. Ghost koi, developed in the 1980s are metallic hybrids of wild carp and Ogon koi and are not considered true Nishikigoi. Butterfly koi, Longfin koi, or Dragon Carp were also developed in the 1980s and are notable for their long and flowing fins. They are actually hybrids with Asian carp and, like Ghost koi, are not considered true Nishikigoi.
