Koi
The Chinese is obsessed with prosperity. Fame seems to be secondary to fortune in our books. Hence the Chinese New Year greeting, ???? (g?ngx?f?cái). Another icon of prosperity is the Carp, or popularly called koi or ? (l?), which not surprisingly features prominently in the decorations for Chinese New Year. Here’s an example:

According to one account, Koi were brought to China from Persia:
It is said that King Shoko of Ro had presented a Koi to the first son of the great Chinese Philosopher Confucius at his birth somewhere between 551 and 479 BC. Confucius named his son (Kong Li, ??) after the fish because it was considered to be a symbol of strength and power. Legend has it that this Koi was the only fish able to swim up the Yellow River falls. Records dating back to this time suggest that these early koi were made up of basically a red and gray coloration.

From here our story moves to Japan, where the Koi were introduced by the invading Chinese somewhere near 200 AD. They have been raised primarily for food in Japan until fish farmers started to notice color mutations somewhere in the beginning of the 18th century. The farmers of Niigata, a Northern prefecture of Japan, were fascinated by these fish and would catch and remove the fish from their food ponds and isolated them. Soon they were breeding the mutations for color and conformation and the koi industry had begun. To this day the Niigata region is the center of the worlds finest koi breeding.
However, there is some doubt about the accuracy of the above account, which might have arisen from the misinterpretation of the name “Lu Zhaogong” to Ro Shoko by the Japanese.
The common carp, Cyprinus carpio, was initially bred for food but later it’s beauty was noted and they were kept for ornamental reasons. The name “koi” originated from the Japanese for “carp”. The name for carp kept for its beauty is “Nishikigoi” (??). A homonym of koi means ‘love, affection’ and koi are therefore symbols of love and friendship in Japan.

Also, the koi is associated with perserverance in adversity and strength of purpose. Because of its strength and determination to overcome obstacles, it stands for courage and the ability to attain high goals. There is a Chinese legend that a carp which succeeds in swimming upstream and hurdling the upper rapids of the Yellow River, called the Dragon’s Gate, will be transformed into a dragon. There is a Chinese idiom, ????? (l?yú tiào lóngmén), literally “the carp leaps up to Dragon’s Gate”, which expresses the idea of a sudden improvement in one’s status.

The point where the narrow river meets the broad segment of the Huang He, there’s a stretch of 100-metre wide fall. Imagine the koi leaping up the waterfalls.
Why are kois painted in odd numbers, particularly 9? Nine koi symbolise longevity. Also, odd numbers represent the “yang” element. Since water is a “yin” element, an odd number of fish will complement it.

And finally, what has koi got to do with prosperity? It’s fish. The Chinese word for fish is ? (yú), which sounds like ? (yú), meaning, surplus. So fish is a symbol of overflowing blessings. As they say… ????.
Icthyos.
