I first shared these Koi 3 weeks ago when I visited Koicentrum van Keulen (www.koicentrum.nl).  You can read more here – http://nishikigoi.life/2015/08/20/visit-to-koicentrum-van-keulen-day-3/ – about the spawning and more examples of offspring at the 2nd selection stage.

The fry are the result of a spawning of the following; 78cm female Purachina (platinum ogon) from Choguro Koi Farm, a male Purachina which Jeroen says was lazy, a male Kujaku, a male Goshiki from Kawakami Koi farm with very dark colouration and deep beni, and finally a Kikusui which Jeroen says seemed to do nothing.

Jeroen’s goal from the spawning was to create a metallic Kuro Goshiki and it must be emphasised again, that is wholly experimental.

Today, 23 days later, Jeroen has conducted the 3rd selection of the Koi and we have some great side by side comparisons of progress in that time.

In both examples we can see a significant refinement and increased definition in the pattern, we can also see the metallic luster is increased.  You can see this clearly in the head shots below.

The other examples below are some that Jeroen believes offer the best chance of developing something like he has a vision for.

As detailed above, and in the previous post, almost all of the offspring have been fathered by one of 2 males, a Goshiki or a Kujaku.  Jeroen believes that Koi above have come from the Goshiki male.

By contrast the following 3 examples are all believed to have been fathered by the Kujaku.

I find it fascinating to be able to follow the Koi in such close up detail.  As I stated previously this spawning was a complete experiment, and the results continue to be a complete experiment.  Only time will tell how close Jeroen has get to achieving his goal.
