Enigma of Shiro Utsuri Part 3

This shiro utsuri comes from the same batch as the shiro utsuri shown in Part 2. However, the sumi development of this shiro utsuri is exactly the opposite even though they came from the same parent namely Musashi.At initial stage, the background of this shiro is pale white and greyish black sumi pattern as seen in photo A.When this koi grow to nissai,the sumi finishes quite well at the tail section and the sumi slowly become more solid gradually towards the shoulder section and subsequently on the head as shown in photo B. I wonder how many shiro utsuri as shown in photo A will develop and become the shiro shown in photo B. In fact, many shiro utsuri from the same batch the sumi tend to fade or the sumi remains sunken at the age of two or three regardless of the sex of the koi.
Some said that the sumi of male Shiro Utsuri tend to emerge earlier than females and vice versa. I have also heard that those fishes with thick sumi at early age will not grow as fast as those with pale sumi (hidden sumi). I personally think that these two statements are not true after having the experience in raring more than 300 shiro utsuri mainly from a few batches of Omosako bred Shiro Utsuri. However, I observed that shiro utsuri with nice pattern and sumi are usually males. That is why most people claimed those shiro with nice black and pattern when young usually grows slower because they are mainly males. It is quite obvious that those females with nice pattern and sumi have been picked by the breeder as their tategoi and of course they tend to grow bigger. Only those female shiro without clearly defined nice black pattern or sumi that has no indication that it will become better, we can own it for a much lower price but a lot more risks compared to what the breeder has picked as their tategoi.
It became very clear to me that small shiro without outstanding sumi and pattern as well as body structure will be sold by the breeder as tosai. Out of these tosai, very few females will turn out to be good unless you are the lucky one.In my case I bought these shiro utsuri in-bulk(300 pieces or more) and a lot of effort is required to grow and sex them as they grow bigger. Not forgetting those cosmetic work required to remove the red spots that appear on the skin of shiro utsuri that needs a lot of hardwork and patience. Ultimately, shiro utsuri came from showa bloodline and that is why red spots can easily appear and especially if it is fed with colour food.
So if you want a safer bet, buy shiro utsuri that are two years old which is more stable but this does not mean that it will be a perfect bet as you still have to take some risks and also much higher purchase price.

Enigma of Shiro Utsuri Part 2

Out of 500 pcs of Musashi Shiro Utsuri offsprings brought in by SPKC in 2006, I have picked roughly about 100 pcs from that batch. This shiro is the fastest growing shiro out of 100 pcs I purchased. At the age of two, it measured about 58cm and at the point of writing(April,2008), it measures about 75cm at the age of 3 yrs old. The growth rate is unbelievable for a shiro utsuri, mainly due to the Musashi bloodline that has a very long and thick body.
In photo A, the sumi of this fish is pretty well-developed with nice menware that looks like it might join with the kuchi zumi(black lips) but somehow that never happened. The black on this shiro faded instead of having more developing sumi as seen in photo B. This is an indication that the fish is still young and the black is still unstable and I am quite certain that the black will reemerge when the fish becomes more mature.The motoguro have also disappeared to my amazement. I had a chat with Omosako's eldest son, Takayoshi Omosako, he told me that in order to justify whether the sumi quality of the shiro is good or not, look at the existing black on the gill cover. If there is strong black on the gill cover, the sumi on the body will most likely appear to be good at a later age. This is just one possible way to determine the sumi development and nothing is CERTAIN. Even the breeder himself cannot be sure whether the fish will develop well or become a champion fish but of course with their experience and sharp eyes as well as careful/in-depth observations of their parents koi (bloodline) and the characteristic of the offsprings, they can most likely pick the better pieces as their tategoi.The shiro shown above will most likely touch 80cm by the end of this year(2008)if given the right conditions that favour the development of this fish. Perhaps, I will post photo C later just to show you the development of the fish on the same post.

Enigma of Shiro Utsuri Part 1

I would like to share my experiences about the enigma of shiro utsuri in a series of different shiro utsuri for each post. I will discuss the important aspects of judging good shiro utsuri and predict the sumi and shiroji development. As you can see,koi in photo A,B,C, and D are the same shiro utsuri at different stages of growth.

Many might say, shiro utsuri with pure black pectoral fins, black tail, and heavy sumi on the head is not good at all as seen in photo A and B.But at a later stage, as seen in photo C, the sumi disappear/faded but the head still seems a little yellowish. In the same photo, the sumi at the tail section and pectoral fins disappeared as well. In fact, the motoguro became so much nicer and it receded to about half the length of the pectoral fins.Ideally, for either showa or shiro utsuri variety, it is good to have 1/2 to 1/3 of motoguro relative to the full length of the pectoral fins.

The striking sumi pattern on the head of photo B can fully disappear as seen in photo C & D. Wondering if the sumi will reappear? The chances are 50%/50% in my honest opinion depending on water parameters. With the right PH,carbonate hardness, and no sudden major changes of fresh water intake to the pond, it will probably help the sumi to reemerge. The process may take months or years but if you are lucky it may appear in a few weeks.

In photo D, the white base on the head is almost snow white unlike photo A & B. So why are you afraid of picking shiro utsuri with yellow head when it is young? It is a risk that we have to take if we rare tosai shiro utsuri. It may or may not turn out to be good. Assuming if you were to buy a stable sumi and white shiro utsuri about 2 or 3 years old with decent pattern, probably it is the best piece out of 20 pieces you bought when they were tosai(one year old fish). So the success rate of getting a good shiro utsuri regardless of sex from tosai is approximately 5% to 10% assuming if you were to buy in-bulk. If we expect to pick only good female shiro utsuri with decent pattern, then the percentage would drop to about 1% to 5%. In some cases, in order to get top class female shiro utsuri with very nice pattern,high quality,thick body structure, and show quality, probably 5 to 10 pieces out of over 300 shiro utsuri tosai that purchased in-bulk and that is only 0.017% to 0.03% respectively.

It may be easy to give negative feedbacks/comments on someone's female shiro utsuri but generally speaking it is still the top 5% to 10% of all shiro utsuri sold in the market. On top of that, do you have a better piece? If, yes how much did you pay for it? Out of how many shiro utsuri you bought are show winners? In a nutshell,in order to successfully keep good adult shiro utsuri from tosai, it requires a lot of patience,time,effort,skills, and money of course.

FOR SALE - Tamaura Tancho Showa

A natural round shape Tancho Showa with a black stripe across the red looks attractive. The sumi on the body are still kage sumi and most likely it will slowly emerge at a later age.Many may think the red spot on the head is too small. I personally think that it is not a problem at all and this fish can be a show fish provided that the sumi appears strongly throughout the whole body. Assuming if the red patch on the head is slightly larger than it is now, how much do you think this female Tancho Showa would costs you? Think again!!!

FOR SALE - Omosako Shiro Utsuri

Inazuma(Lightning pattern) shiro utsuri that looks so striking and very well-polished black. It looks like a male but at the time of checking the sex of the fish, I was not really sure. However, I am hoping that this shiro will turn out to be a female. This fish grows very slowly and I have always been keeping this fish thinking that it is a male. The luck is yours whether it will turn out to be a female at a later age. It has also won 3rd prize in Utsurimono 40bu category in the most recent Malaysia koi show and championship.

Size: 39cm

Sex: Unknown

Age: Nissai (2 yrs old)

Price: RM1500.00 (SOLD)

FOR SALE - Omosako Shiro Utsuri

This shiro utsuri is the biggest and fastest growing out of a lot of 120 pcs I bought in July 2006.Many turned out to have red fins,red eyes, and red patches on the body and majority are male fishes. I would say approximately 90% were males and many were given away or sold at a lost. The remaining females, only a handful turn out to have better sumi quality, good white base,structure and pattern. Some of them faded beyond recognition.Most of the female shiro utsuri from the same batch, they hardly touch 55cm or most of them below 50cm, while this shiro is touching 60cm (April, 2008). I seriously think that this is a jumbo shiro utsuri. It has won Best in Size 25BU Utusurimono in 2006 when I first purchased this fish and the one sided motoguro did not deter the judges from awarding this shiro Best in Size 25BU.
This shiro has very broad shoulder and a very unique black pattern that is hardly seen on a shiro utsuri especially the black patch on the shoulder that blends/matches well with the kuchi zumi (black nose). An interesting fish to add to your collection!!!

Size: 60cm

Sex: Female

Age: Nissai (2 yrs old)

Price: RM6500.00
