Hints for Picking Tosai Gosanke

Hints for Picking Tosai Gosanke

It's always best if you can see the parent Koi. They should have very good "body", "skin ground" and then "Hi and sumi quality". The body line from the shoulder to the tail is most important. Volume, and bone structure, is important but especially a thick tail tube.

The skin should be a gentle white color that looks soft and thick. It should have depth and dimension. It should be like looking at silk, not cotton. This is a better quality than solid pure white.

Mesu or Osu?
There are some ways to help determine whether a Tosai is male or female but none of them are 100%.

Color - It is often said that the Tosai with the brighter Hi are male and the softer, yellowish Hi are female. Sometimes is does prove wrong and you will find, whether it is male or female, the deeper red tends to be hard Beni that will not last as long.

Skin - The quality of the skin can be a dtermining factor as well. Soft skin can be an indicator that the Tosai is female but this "softness" can be difficult to determine.

Fins - On the whole the pectoral fins can be a very good indicator. males tend to have rather long, and wide fins compared to it's body. Some lines, like Matsunosuke, don't work well with these indicators though.

Body - Some Tosai will display, at an early stage, the features of larger female Koi. They tend to have more of a rounded belly but, for most, this doesn't become an indicator until they are 8" - 10" in size.

Bottom line, Tosai are a gamble when trying to determine sex.

Kohaku Tosai

Beni Quality

It is very important, when you pick your Koi, that the beni have what is known as Nerikomi. Nerikomi is the depth, and eveness of the Beni. When you look at Beni that has Nerikomi it makes the Hiban plate look uniform and the scales, or scale mesh, tends to blend or look vague. If the Beni is thin the scales tend to stand out and it doesn't matter whether or not the Beni is light or dark. Look for Beni that blends the scales together and don't look at the tone of color. When you can do this you will find better Beni.

Sashi

Sashi is the area at the leading edge of the Hiban plate. We are told to look for Sashi as a determing factor in quality Beni. Sashi is not important in young Koi and is not what determines the quality of Beni. Some will say that the uniformity of the sashi is what determines the quality of Beni but it isn't and Sashi that is uneven, or wider than one scale, is usually an indicator of higher quality Beni.

Kiwa

Kiwa is the edge at the back of the Hiban plate. In young Koi you should not be concerned if it is uneven or blurry. Kiwa is an indicator of the "finish" of a Koi. maruzome Kiwa, which is the Kiwa that forms to the shape of the scale, is found on high quality Beni. It will finish slowly and starts finishing from the bottom of the Hiban plate to the top and from the front of the Koi to the back. The longer it takes to finish, the better. Male Tosai Kohaku tend to show good Kiwa.

Hi on Fins

Hi that is found on the dorsal fin will receed down to the body over time but avoid Tosai that has Hi going up the front bone of the dorsal fin. If the Hi is touching, or just on the front bone it will usually pull forward when the Hiban plate receeds forward but, if it is too far up it will not.
Hi on the pectoral fins will receed to the base of the fins.
Hi on the tail fin will usually never disappear so be careful with this.
Hi with strong pigment will appear evenly on the fins.

Hi Patterns


This is a very subjective part of picking Koi. I think you should always go for what strikes your fancy, as long as you have made a good determination of the quality.
There are several "rules" that should help you a long the way though.
1. A Kohaku should have a white nose. there are always exceptions but remember, Kuchi Beni refers to beni on the lips of Koi, not their nose.
2. There should be Odome. This is a white area between the last Hiban plate and the tail. This is also a rule that I feel has an exception as well. High quality Beni will contract, and pull forward, as a Koi grows so, as long as the Beni is not in the tail, but to the tail, you should be OK and the Odome will appear as the Kohaku matures.
3. There should be a good balance of red and white. This becomes subjective as well as well all have our own ideas of what "balance" is. Furthermore, balance can be determined by what stage of development the Koi is in. For instance, if you purchase a 6" Tosai with a small, flowery pattern, it may look very nice until that Kohaku is 16". When it is 30" the pattern could end up looking very small. It works the other way as well. I like to pick Kohaku Tosai with "big fish" patterns because I am an optimist. I believe that Kohaku will get to 30" and then the pattern will suit it much better.

Shiroji - Skin


The "whiteness" of the skin ground is usually described as snow white but pure white, or bright white, is not always the best quality skin. There needs to be a depth and luster to the skin, I look at how it "glows" to determine this quality. Bright, snow white skin with a cotton sheen is not a good quality skin. A fresh, cream white skin with a silky sheen is much more appealing.

Tobi - Quick Growers

When picking any Tosai don't be fooled by size. Tobi are Koi that grow quickly and are lager than their sisters and brothers. Most quick growers tend to be males.

Showa Tosai



Showa Tosai, I think , are the most difficult to predict, but I also feel they bring the greatest reward. I think what makes Showa so difficult to pick, at Tosai, is that we all want what we see in pictures of finished Showa. The problem is that, if you buy a Showa Tosai that is like the pictures, you won't end up with a very pleasing mature Showa. As it grows it will change and nots in ways you would expect. In fact this is the case with any finished Tosai, they only go down from there.
Having said this I thought I would still offer some tips I have learned to help you develop the patience, and skills needed to enjoy Showa.
