Koi Varieties

Doitsu

In the early 1900’s a few of these Doitsu (doyt’zoo) carp found their way from Europe to Japan where they were crossed with the normal scaled nishikigoi (wagoi).  These carp either lacked scales, or had enlarged but reduced number of reflective scales distributed either at random or in delineated patterns over the back and flanks.  Once the genes of the doitsu carp has been established in a carp/koi population, it is almost impossible to breed out.

Today there are four main scale patters in koi. The fully scaled (wagoi), the leather koi that have no scales on the body and flanks but only very small scales along the dorsal line, Linear koi with large scales along the dorsal and lateral lines and armoured koi (yoroi) that are partially scaled koi that have scales other than along the lateral and dorsal line in jumbled patterns.  Of the latter three, only leather and linear koi are of importance to hobbyists interested in Doitsu Koi because armoured koi are usually culled and are not considered to be of high enough quality to be worth entering in competitions.

The Japanese are not keen on Doitso fish because they see them as unsubtle and two-dimensional.  In fully scaled koi it is difficult to achieve sharp pattern edges (sashi and kiwa) because scales overlay colour plates. The Doitsu koi do not have these problems.  Because of the difficulty in finishing a fully scaled koi, it will always beat a Doitsu in competitions.  Despite this, the Japanese keep on producing Doitsu koi, mainly because of its popularity in Western Countries.

In recent years more Doitsu koi have been deliberately bred from recognised varieties, particularly in the Kawarimoro, Hikarimuji and Hikarimoyo classes.  When naming Doitsu koi, it retains the original variety name with the prefix “Doitsu”.  For example Doitsu Kohaka, Doitsu Showa etc.  Examples of Doitsu koi that are varieties in their own right are Shusui, Midorigoi, Kikokuryu, Kumonryu and Kikusui.  When judging Doitsu Koi a lot of emphasis is placed on evenly sized and symmetrically aligned scales.
