Dear valued members,
My father just turned 60
years old this month. In Japan, the 60th year is called "Kanreki."
At sixty years of age, the sexagenarian cycle is completed and we
return to the zodiac sign of the birth years. So we in
Japan celebrate their sixtieth birthdays and wear a red vest on
this day. Red vest not only means that they come back to the baby
year but also red is the charm against the evil.
Though I
was not able to celebrate his Kanreki in Japan, I presented the red
vest and hat. It seems to be really interesting to see him in a sort
of baby clothes :) If I am lucky enough, I can get the
picture from him and show you on the next newsletter.
This newsletter features Spawning of the famous Isa Koi Farm. I
am sure you will find it very interesting. Please enjoy.

| Breeders say
"Silk worm pupea is the best food for
Koi" |
 |
 |
|
Top Quality from
Kawaguchi Shoten Co.,
Ltd. |
Japanese Silk Worm Pupea
In Summer time when is the best growing season of
the Koi, breeders release their Tategoi to large mud ponds.
Then, they feed silkworm pupea.
From the experience of the
breeders, silkworm pupea is the best food to grow Koi plump
and lustrous. Scientifically as well, this is proven. The
proportion of protein is very close to the composition of
protein Koi has. So Koi can absorb the protein of silkworm
naturally and effectively.
We buy silkworm pupea from Kawaguchi Shoten, who
is an established silk dealer. They always make FRESH dry
silkworm pupea available for breeders and Koi hobbyists in
Japan.
You may not want to feed only pupea to your Koi.
But as a treat, this is a great source of nutrition. I
definitely recommend this for the serious Koi keeper.

1)The extraction of spawn of Koi
When water temperature
reaches 20 degrees (68 F) or more, production of Koi
begins.This
period (water temperature of a pond rising to 20
degrees) is at the beginning of June in Niigata or the end of May.
At that time virtually 200 breeders in Niigata start the extraction
of spawn all at once.
I was present at the extraction of spawn
of the famous breeder, Isa Koi Farm of Showa this time.
Naturally laying eggs, They let the female Nishikigoi* purse two
or three males at once, and this is a general method of laying
eggs of Nishikigoi. However, I do not understand which sperm of
which male crossbred it for a female egg with this method. Therefore
there is ambiguity in doing selective breeding. Now,
most of these methods are not practiced.

2)Artificial extraction of
spawn
The method of artificial fertilization of Nishikigoi
was established 25 years ago by Prof. Kurokawa of The University of
Tokyo, science of fisheries section, and it was tried by an advanced
breeder.
"Artificial extraction of spawn" has a lot of merits to
make beautiful Nishikigoi, and over 95% of breeders adopts this
method.
For "Artificial extraction of spawn", Isa Koi Farm uses
parents Koi that easily worth more than 5 million yen
($42,000).

3)The eggs of Nishikigoi
Nishikigois eggs stick
to green algae.
It is this technology of the breeder that lets
the eggs stick unifomly like on a photograph.
Because the
breeder has this high technology, they can stick them like this
evenly for a photograph.
Isa Koi Farm carried out
extraction of spawn for more than 15 years, but adhesion of such a
wonderful egg was learned in a long amount of time.

| These are called
"Kego" |
Incubation of Nishikigoi
(birth)
When Nishikigoi lay eggs and passes 3rd, their
eggs surely hatch.
A fry just after incubation is called a
Kego(a young fish). meaning
small and thin fish that
resembles hair.
The breeders discharge these young fish into
their raising Pond of Nishikigoi and bring up them.
The
beginning of June is "taking eggs" season of Koi in Niigata every
year.
And born fry are brought up in the pond of fry for
exclusive use.

|
|
| These fries are
called "Chigyo" |

The left photograph shows hatchlets,
and it was taken after the 30th. When a fry is compared to
a young fish, it is known that they will grow
large like Koi.
And a design appears according to growth
slowly.
Three months later from now, these fries will grow
10-13cm (4-5 in) and will become a beautiful figure of
Koi.
