Shusui which means “autumn water” in Japanese language is also a koi carp variety that closely connects to the asagi. They are basically Doitsu Asagi meaning that the koi have no scales except for two blue colored lines running parallel from head to tail appearing on each side of the dorsal region. Similarly like the asagi, the head must be clear white without presence of any visible marking while the red hi distribution should cover the lower region of its body. There are generally two different types of shusui identified by hobbyist, one considered the more common which is the Hi Shusui and another is the Ki Shusui which is basically a yellow colored variety of the same koi fish. Apart from these two, there are also several forms of the fish classified under its own group normally based on its color pattern and distribution, notably the Sanke Shusui and the Showa Shusui.
My experience seeing the real specimen was during the local club organized koi competition whereby I got the chance to see two of the finest fish being displayed. To the owner showing off his pet was indeed a proud moment and to every one of us who are present there, we consider ourselves lucky to be able to witness and see for ourselves the fish and I could hear the praises coming from all the participants who attended the event. Of course, we can’t deny the fact that the koi was quite rare at the place where I came from as it have yet to gather true followings and remain largely unknown in the local scene. Somehow I believe for true exposure and to really study the fish would require one to really travel to Japan, the birthplace of koi and witness how they actually breed and raise the fish. Of course, we consider some of the local hobbyist who are able to afford to travel there to gather knowledge and maybe bought along a few specimens are so far the ones most fortunate.
