The egg of “Cats” exceeded last year. 2165g ! !

<Comment in movie>

Can you believe this? “Cats” spawned 2165g of eggs!! It is more than last year! We installed new technique to raise ratio of hatch. From easy calcuration, 1g = 700 eggs. If 90% of eggs would hatch, 1.5 million of frys!! Wonderful . . . Can not stop dreaming about it . . . However, one error leads as no result. I will concentrate on it. In addition, couple hours later, “Dango”(Showa) and New Kohaku(No name) delivered eggs. We took seven days to let “Dango” spawn. The amount of egg was 1,700g and I’m very satisfied about this. I wish ratio of hatch and black fry goes well, too.


The moment of “Cats” spawning

<Comment in movie>

Finally, “Cats” start spawning. As you can find from this film, male koi chase female from back. When male koi rub their body on female, we remove female into different pond and let them take a rest at least one hour. Then we start artificial spawning. Well, let’s see how many eggs does “Cats” can provide this year. As you can find from previous film, “Dango (Showa) and New Kohaku (No name) successfully spawned.


Showa spawning are done. Kohaku and Sanke are coming.

<Comment in movie>

Hopefully, spawning of Showa are mostly completed. I was bit worry how it goes because early paring didn’t went well. However, as a result, ratio of hatch and black fry is almost same as last year. It means, we are doing very well. We still have one Showa paring to go but we start using Kohaku and Sanke. The Showa you can find in the film is called “Dango”. It doesn’t spawn well but I will wait for a while. The Kohaku in the film is “Shirayuki” which was first use last year. The atmosphere of ”Shirayuki” Tosai is. . . .very nice . . . Another Kohaku is new comer and no name yet. The sisters of its koi took Grand Champion at Kanto Kosietsu district and Tokai district. It is still 5 years but 84cm already. This koi has kept good quality since it was young and I have kept this koi for parent. This is the debut year ! At last, I would like to introduce “Cats”, Sanke. Last year, it gives over 2kg eggs! I’m expecting on you again! As same as last year, if spawning of “Cats” went well, I will not take any other Sanke spawning. I do expect and love with this koi.


“Chokan-sho” spawned at last . . .

<Comment in movie>

We finally succeeded spawning of Chokan Sho which is the oldest and the most important female parents at Isa Koi Farm. There is one Showa which was the origin of Isa bloodline and there are only three children of its original Showa. Chokan Sho is one of these three. Matter of course, children of Chokan Sho also take important places of our production at Isa Koi Farm. I’m very happy that spawning become successful. Wish she provides good candidates of parent fish . . .


Spawning is started

<Comment in movie>

I’m sorry that I haven’t updated blog for long time . . . To be honest with you, this moview was filmed on June 10th and I was going to upload this kind of movie day by day. However, the start of spawning was two weeks later than usual and main parents fish hadn’t been spawned for a while and exhaustion and lack of sleep and stress and etc. All these matters drove me away from computer. Some customers sent me message that I should update blog more often. . . . I’m sorry . . . However, hopefully, things are getting better now. Main parents and new parents gives good ratio of birth and Kuroko as usual. Fry will be released into pond soon. In addition, I have tried new technique of spawning which was advised by Sekiguchi Koi Farm and Niigata Prefectural Inlandwater Fisheries Experiment Station. Thank you very much for your helpful advise, Mr. Sato and Mr. Sekiguchi! I would like to report how fry grows through this blog, so please visit check our website. As you can find from movie, Mr. Hiroshi Muto at Tokyo Kanshogyo has been working at Isa Koi Farm as trainee. He loves living thing and also has stamina so he already started working very well here. He may appear on our blog, so I appreciate your sincere support towards him as well.


“Shirayuki” Kohaku of Ake 2sai are released into mud pond.

<Comment in movie>

I would like to introduce Ake 2sai(It was Tosai last year) of Kagura bloodline. Name of parent fish is “Shirayuki”. Because these Kohaku has strong body structure, they eat more than the others. Therefore, I can not put these fishes into same pond. It goes very well thought . . . . I can not wait to see how it grows when we harvest. Second video below first one is the film which was introduced on our blog on Sep. Please take a look.



Ake 2sai are released into mud pond.

<Comment in movie>

I’m sorry I haven’t updated blog for long time. Today, I would like to report releasing 2sai(Tosai last year) into mud pond. The size of koi is around 30 to 40cm. We could release these because water tempreture is getting stabled. The bloodline of Gosanke you can find from this movies are, Cats for Sanke, Chokan Sho for Showa, Boshu for Kohaku. I like these three parents because they have strong and stout body structure. These three bloodlines can be well expected in the future. I can’t wait to harvest them !!
