Shusui Grade A Koi Carp Cyprinus Carpio

Shusui (SHOO-soo-EE) koi are a grey-blue koi with a very striking red pattern along the sides of the fish and in the cheeks and fins. The Shusui koi also have no scales over their body except for a row of large scales along each side of the dorsal fin. These koi are very valuable to the history of koi as they started the scaleless variety of ornamental carp and, over the years, this scale-type has grown to over a hundred different varieties!

The Doitsu scale type originated in Germany when an Asagi koi was bred with a German Mirror Carp in the early 1900s. These Mirror Carp had a genetic mutation that resulted in certain growth genes not developing properly. This mutation was commonly seen in many types of carp including koi and zebrafish as well as thousands of other species and is visible in the form of a lack of scales or a fully scaleless fish. When the gene mutation was first spotted in Germany, the fisherman encouraged it and grew the population of fish with the mutation as it made preparing the fish for cooking and eating a lot easier and quicker. Eventually, many species developed to the point where every fish had the mutation.

After hearing about these scaleless fish in Germany, many other countries wanted them as they vastly reduced the work and time required to prepare meals and were therefore very valuable to the fish merchants and many other businessmen. One of these countries was Japan and once some of these varieties of carp, including the Mirror Carp, were imported into the country, fishermen quickly got to work introducing these new scaleless carp into their populations of carp to spread the gene mutation.

By this point, koi carp were already being bred as ornamental carp by breeders across the country and the Asagi koi was well-established. It was one such breeder, Kichigora Akiyama, who decided to breed an Asagi with one of these new Mirror Carp, which is the scaleless version of a common carp. Within only a few generations, a new variety of koi had been developed that looked like an Asagi but had the scaleless gene mutation to drastically reduce the number of scales on its body.

This new fish was originally called a Doitsu Asagi after the Japanese word for Germany, ‘Deutsche’, but the variety quickly developed and became less like the Asagi koi. As the Doitsu Asagi became more popular, it was renamed to Shusui which means ‘autumn water’ and refers to the pattern of red colour on a blue background looking like red leaves that have fallen from a tree to land in the river. The term Doitsu meaning scaleless koi stuck, however, and is still used today to refer to scaleless koi.

Great dressy sneaker to wear with business casual or jeans
Size: 11, Color: British Tan/Ivry
I got these for my husband to wear with jeans or business casual dress pants. They look sharp and professional and dress up jeans if you're going out. He says they fit comfortably and he can walk on them all day without his feet hurting. They are beautiful genuine leather so they don't get stinky. I got my husband's normal size and they fit to size.

Comfortable

Most comfortable and roomy shoes I ever wore. Great for insoles. Looks nice too. The base of the shoe is a bit too thick but it’s fine.

These are awesome shoes - look great really, really white and clean! Love how comfortable they are - and soooo light. I was a little worried they'd get dirty easily, but I've been able to keep them clean. Fit as expected. If you're looking for a great, comfortable, and affordable shoe, check these out!

Great shoe, comfort
Size: 11.5, Color: British Tan/Ivry
Love these shoes, they're super comfy. Laces stayed tied all day. I wear them in a business casual environment, or if I'm going out for a nice meal with my wife. They look good, the color is unassuming and neutral. they also elevate my height, I feel like it gives me an inch or so more versus regular shoes. This is my second pair!
