Mitsunori: Today, we would like to start with a report of our developing nisaidate.
We have 60 koi in this mud pond that sizes about 1 983.47square meter.
It’s been passed 3 weeks since we started feeding them. Even though we give them little food for now, they are getting bigger.
At such times, we feed them the small amount of food, which isn’t satisfied its appetite, five times a day.
I wish that they would grow into 55cm to 60cm long in this autumn.
Eat more, Get bigger!
The fertilizer has been sat for 3 days. It looks like this now. As we reported previously, it contains rice bran, poultry manure, water, and the special bacterial liquid.
It’s moisture and like this firmness, which a lump breaks when a hand holds it.
We usually make the amount of approximately 700kg to 750kg at a time. Now, Hirasawa (Hidemasa) and Hara are helping to pack the fertilizer in paper bags. Mitsunori: He professions the packing process. Hidemasa: Oh, yeah! If there is such a game in the Olympic program, I can be…fourth place. Everyone: hahaha Mitsunori: But, you work slower than usual. Hidemasa: It’s all Hara’s fault. He’s feeling bad today. Everyone: hahaha
Well, like this, we pack the fertilizer in bags and load them on a truck. The all fertilizer bags are going to fit on the entire back of the truck. Mitsunor: Good luck, guys. Hidemasa: Ok, thanks. Mitsunori: Oops, it fell down.
Hi, today we report day 2 of making the original fertilizer. We add more rice bran and poultry manure at this stage.
He makes a bag of rice bran look lighter, but actually it is heavy. Hidemasa: Yes, it is. Mitsunori: Like this, add rice bran to the fertilizer sat overnight. Then, here it comes the poultry manure. He didn’t even drop a single piece. Hidemasa: Of course, I never drop it. Mitsunori: Add several baskets of poultry manure. This is the poultry manure.
We fortunately get baby chiken’s feces this time. It’s good quality poultry manure. We will run the machine all day today, and it’s going to finish tomorrow.
We would like to introduce how we make Sannichi-kai’s original fertilizer.
At first, we mix rice bran with water in a mixer. And, this is the special bacterial liquid. We add it equally, and then pour water at last.
We let it sit overnight and will add poultry manure tomorrow. It takes 3 days to finish making. This is the preparation stage that mixing rice bran, water, and the special bacterial liquid. Mitsunori: Is everything ok so far? Hidemasa: Yes. It tastes good. Mitsunori: Is it? Hidemase: Evidently.
We use this fertilizer to increase the number of water flea in ponds. Afterward, we don’t give any food to tosai except the water flea and fertilizer. Well, we’ll report the day 2 later.
Today, we are culling the kego (baby koi) that hatched from Chokan Sho’s eggs at the house over there.
We created the quarantine area with blue plastic sheets to keep the fertilized eggs and waited for the hatching.
Here we are. This is Chokan Sho’s kego quarantine pond.
The eggs weighted over 2,3kg, and the most of them were hatched successfully.
Their father is the koi bred by Dainichi, which received the 80th division Kokugyo prize. His name is Higuma.
The kuroko rate seems high.
Our precious oyagoi, Chokan Sho, we wish her babies will grow healthily.
It’s 4:30 in the morning on June 11th.
We’ve just finished the fertilization process between Chokan Sho’s eggs and the two male’s sperms.
Fortunately, we could harvest many eggs, which amounts over 2300g, from Chokan Sho, and she became one of the key oyagoi at our farm.
Please look forward to seeing Chokan Sho’s children. Hidemasa: It’s already early in the morning. Aren’t you exhausted? Mitsunori: No, not at all. Rather, it’s hot. Hidemasa: Yeah, you are sweating. Mitsunori: Because it’s warm in here. Well, we need to wait for another female koi to spawn. We’ll start working in the daytime so I hope the female finish spawning by then. Hidemasa: So far so good? Mitsurnori: Yes. Our oyagoi keep on spawning many eggs, over 1000g, so we have to catch up with kuroko culling. It’s a rich harvest this year. Hidemasa: We’ve chosen Chokan Sho as our main oyagoi since last year. We are happy that the oyagoi has spawned numerous eggs. Mitsunori: What do you think the reason for this year’s rich harvest? Hidemasa: Hmm, what do you mean? Mitsunori: It is about our good deed. Hidemasa: Oh, I see. That’s right (laugh). Well, good luck for the rest of your work. Mitsunori: See you soon.
Today, we would like to start squeezing sperm out of male koi to fertilize with the harvested Chokan Sho’s eggs.
We picked out 2 males.
One is this Showa.
This male, which bred by Dainichi, won the last year’s 80th division Kokugyo award at All Japan Combined Nishikigoi Show.
Another is this Showa.
We breed this male. The parents of this koi are both massive koi sized over 90 cm long.
We’ll get the sperms from these koi and continue to fertilize them with Chokan Sho’s eggs.
We finished squeezing eggs out of Chokan Sho.
The eggs are very beautiful light yellow.
Surprisingly, the amount of eggs is 2.31kg.
Chokan Sho spawned many eggs again this year.
As for the rest, we only wish high percentage of the kuroko.
Chokansho, the oyagoi that won the fisheries agency award last year at Nogyo-sai, produced eggs.
We are putting it to sleep with an anesthetic and then squeezing eggs out of its ovary. Mitsunori: It seems there are many eggs inside. Hidemasa: Yeah.
Well, we are going to harvest eggs right now.
We introduce our Kuroko culling today.
On June 9th, this is the first kuroko culling in this year.
These baby koi were born from Kuro, female, and Marbou, male. They should become superb koi.
Like this, we select only kuroko. There are 8 people including helpers. This job is not easy. Hidemasa: How good is the percentage of kuroko in the baby koi? Mitsunori: We have enough kuroko. It seems that this year kuroko is less than last year but not bad at all. Hideamsa: Good. We work whole day like this.
Well, good luck! Everyone: Thank you.
