    Recreating The Yamabuki?

    At the end of the month, Momotaro is having an auction of tosai. Individual photos of gosanke tosai are available for advance viewing on the Momotaro website. There will also be an auction of yellow Ogons of various shades. These are not individually photographed. There is a very short video clip of some of the many available. These are the koi I find most interesting from among all the ones being auctioned off to dealers. Why? ...Here is what the website has to say about them: "These are from Ogon mixed with Karashigoi bloodline. These will grow very big with big bodies." Momotaro koi nishikigoi kohaku sanke showa Japan

    Momotaro has crossed Karashigoi with Ogon (presumably Yamabuki, but the website does not say). The tosai shown in the video clip have the look of nisai. I am impressed by them. The head structure and body form is much like Karashigoi. The Yamabuki can vary a great deal in ultimate size. Izumiya became famous for producing meter plus Yamabuki, but comparatively few reach a meter in length. A much larger proportion of Karashigoi exceed 90cm. Yamabuki often have problems with the shape of the head, while Karashigoi typically do not have many issues with conformation. It seems Momotaro is setting out to produce a Yamabuki-type koi with the massive body structure of Karashigoi. This is an example of breeders continuing to work to improve established varieties. The range of genetic variation within koi may be such that no more truly new varieties will be created, but there is no end to the pursuit of improvement.

    I have not had a Yamabuki for a few years. Koi Kichi tend to consider them ordinary. Everyone else will tell you that the Yamabuki is the most beautiful koi of all. It would be great fun to have one of these grow to a meter in my pond.

    Wonder how the depth of the metallic sheen would be on these cross spawning for size....
    The world sleeps as the chance to learn something new passes.

    How he could grow them in a year to looking like Nisai or even Sansai?

    Unlike the traditional koi breeders of Niigata, Momotaro has a very modern production facility designed to promote year-round growth of selected koi. It is not unusual for Momotaro to produce 40-50cm tosai by Spring. Their facilities are designed to maximize growth. If you checked out the tosai being auctioned today, many are over 40cm. However, most being auctioned are in the 25cm-35cm range. People get the idea that the larger ones will grow bigger. That is not necessarily true. The larger ones may have been produced in early spawns. The smaller ones may be from summer spawns. Some years, Momotaro is spawning koi as late as August. The key is to provide warmth, constant feeding and continuous flows of fresh water. There is much expense involved, but Momotaro has learned that it can sell a 45cm tosai for a much higher price than a 20cm tosai. By the time a tosai reaches 35-40cm, it can generally be sexed accurately. As a result, Momotaro can sell off the males sooner and target females for high growth. People will pay more for a tosai they know is female, and when the tosai is 40cm or larger it is much easier to be comfortable predicting how it will turn out. I tend to think the pricing of jumbo tosai is too high, but compared to taking a 50-50 chance on a small tosai turning out male, perhaps not. Compared to buying a small tosai, you save the expense of feeding for a year only to find you have a male you do not want.

    Many breeders now produce 'jumbo tosai', but not in the quantities produced by Momotaro and SFF. And, not many have the facilities to produce tosai over 40cm.

    Check out the 'equipment' page at the Momotaro website to see the scope of their facilities. Only SFF and Dainichi are in the same league, IMO.
