Re: [newgen] How to breed kois ourself? [In reply to]	Can't Post

Firstly, where do u intend to put the fry once they have hached??? Do u have the space? What do u plan to do with them, after all, u do know there will be about 50000 of them, and that u have to cull at least half, and once thats done, u still have plenty left over.

Now, the way to do it is: First u need a shallow pond where u will have the koi to hach. U can use a inflatable baby pool or something like that, but if the water gets too hot, they will probably die. Now, u have the pool, u put in something for the eggs to stick onto, like tied together branches, or a synthetic material. Keep the temperature from fluctuating. Put in the male and female u want to mate, or u can use two males, but they could severely hurt the femle, while smashing into her to make the eggs come out. Keep the pair, or the three in threre till all the eggs have been deposited, then take them out, as they will start to eat the eggs. It is best to put the female into quarantine, as she will be succeptible to diseases at this time, as her slimy coating is all beaten off. After 3-5 days the babies will hach, and u need to feed them a special gel, that u can buy, or, if u run out, then boiled egg-yolk, though they love this, it is not good for them. U need a very slow filtration in this pool, and a mesh over the intake, so the fish wont get sucked in. Then, comes the culling and so on, but im not going into that, itll take too long.

Personally though, if u havent anywhere to put the babies once they are bigger, u shouldnt try to breed koi. Smile

Thanks koihaku!

Erm...by the way, how to prepare them to breed in a FG tank or the baby plastic "pool"? can i put a mop head in it to hold the koi eggs? THEN? how to make them lay eggs? please tell me steps by steps! until they can breed! thanks!

Coz i wanna help my friend breed his kois~ he has an extra FG tank currently not using, just only pumping water through the filter...that's all~

So he wish to breed some kois and he can give some away~

Anymore good suggestion?!

U can't MAKE them lay eggs. They'll spawn when they want to. U should get a gravid female (She has a huge belly full of eggs and that's a sign that she's about to spawn.). Put her in the spawning tank (with spawning mops) for a day or two, and after that introduce 1 or 2 male fish. They should spawn naturally. If they don't after a week, try again some other time.... they might just not be ready. The kois should be at least 2-3yrs old. IMO, preferably breed kois that are 50cm+ just so that they are more likely to pass on the genes for growth and are not stunted.

Frankly, it's not viable to spawn your own koi simply because you'll be needing a HUGE amount of space and tanks for the couple of thousand fry you'll get. As it is, there is an over supply of local koi bred in Malaysia and they're cheaper to buy than to raise them yourself. The fish farmers in Ipoh have huge mining ponds to raise their baby koi without any extra cost whereas u'll have to spend so much money buying FG tanks, pumps and filters to raise any significant number of kois.

If you're doing this just for the fun of it, I suggest you keep just a few fry and discard the rest. I get the occasional spawn in my ponds and sometimes find tiny kois in the filter (sucked up from the bottom drains). Only 2 baby koi have been saved to grow on, 1 shiro utsuri and 1 hi utsuri because they look like something classifiable.

Re: [KevKoi] How to breed kois ourself? [In reply to]	Can't Post

The eggs come out because the male smashes the female into the sides of the pool, thus forcing the egs out, while at the same time releasing sperm. Thats how it usually works, and thats why the female is tired and prone to diseases afterwards. And yes, of course u can put the mop heads in. There are of course ways to make the eggs come out artificially, by rubbing the females stomach, but thats too complex.

Anyway, happy breeding Wink

Re: [koihaku] How to breed kois ourself? [In reply to]	Can't Post

Hi All,

Breeding koi was not something I really wanted to do, it just so happened that a couple of my older koi (3 yrs), decided to get a bit frisky.

I did not move my koi from the main pond when they started to breed as I thought a new environment would only stress the female more. I wanted her to be as comfortable as possible.

I used mop heads as apposed to spawing ropes. Make sure the mod heads are clean, brand new from the shops are ideal afer rinsed with pond water a few times. Obviously don;t use the one in the cupboard that you use for the kitchen floor Unsure

. Also if you can get a darker colour other then white, this is idea as it won;t camoflauge the eggs.

Tell tale signs of breeding. The female will become well developed around her middle. look toward the start of the tail, if you see a sudden uplift from the body to the tail then shes a female (other ways of telling them apart is by their fins and gills plates, but we'll get into that at another time if you want).

The males will develop a rough surface on their gill plates, some people confuse this for infection, but they use this rough surface to brush against the female. The males will also develop very small white lumps on their fins. They will not develop any n their tail or body. This can easily be confussed with desiese at the start, unless you have seen them before. If you loook closley at a post I made called "a loverly couple", you can see the white lumps on the shusui's front fins.

The male will start to chase the female around the pond, The female will look stressed and may jump a few times. But after she realises that the male is the best father for her off spring, she will settle down. keep a close eye on them and check the mop head fequently. The eggs could arrive in an hour or a week.

You will know just beofre the eggs arrive as the male will start to nudge the side of the femal with his nose.

When you find tiny white eggs on the mop heads, move them to a q-tank with gentle flow and gentle oxygen. As suggested by others above. I would persoinally take water from the pond with them, any sudden change of parameters of temperture will wipe the eggs out straight away. I doubt that you will get 50,000 eggs unless you actaully catch them spawing. I think I have about 1 - 2 thousand, the other kois in the pond helped themselves to the rest.

Once the breeding has finished, you should move the female to a hospital tank and salt to 0.3%. This will incourage the mucas gland to produce more mucas to replace that lost in breeding. Leave her in ther for 2 days and then return to the pond.

It can take up to 4 weeks for the eggs to hatch. Fish flakes (crushes up) or gel as reccommended above is ideal for fry.

Not sure why someone above suggested eggs yoke and then said it was not good fot the koi. It may have been a typing mistake.

Have fun and happy breeding

Stuart

P.S. My koi fry should be hatching any day now, the eggs are starting to shine, which is a good sign that they are ready.

Re: [SMW1] How to breed kois ourself? [In reply to]	Can't Post

THanks Stuart for enlightening us on koi breeding! Congratulations! You are gonna be a 'father' soon! Let us know how they are doing, OK? Wink

I agree with you that you should quarantine the female after breeding as by now she would be weak and lost a lot of the slime/mucus on her body. Any further stress would be detrimental to her health. I would keep her in the quarantine tank for at least a week with 0.3% salt as well.

I use the regular pellets that I feed the adult kois but they are crushed to a fine powder for easy eating. Once they are a little bigger, you might want to include daphnia or tubifex worms in their diet.

I also agree with Kevkoi that unless the eggs are from the product of two Japanese kois, the effort spent to bring them up to adulthood can be quite space, time and cost consuming! Unless, in Stuart's case, it wasn't planned! No family planning, Stuart?!! Cool

Hi Stuart!

Woe be unto us all the day they do make contraceptive devices for the kois! Wink

Anyway, enjoy your 'fatherhood' and let us know their progress! I am sure they will grow very quickly once they hatch.

All the best!

After reading I felt it was so hard to breed. I might as well buy the koi from a dealer.

But is there any chance that they might breed itself in the pond without us knowing?

If there is then I'll pray hard for it.

Re: [fortune] How to breed kois ourself? [In reply to]	Can't Post

It's happened for me b4. The koi may spawn in the main pond and the eggs get sucked into the filter chambers and hatch and grow up there. Any eggs left behind in the main pond is going to be supper for the rest of the koi.

I've had some new small koi appearing in the filter chamber b4.

I think, in your case of a pump fed filter, that would be quite unlikely 'cos the pump will mince up all the egss b4 it's deposited into the filter..... Frown

. Another down side to pump fed filters(?). Crazy

Wow... newgen.. That's a dangerous filter... Cool

So how you manage to save them.. Relate the story to us...

Anyway.. Kevkoi, I'll be using 2 Submersible pump(1 for fountain and 1 for Statue) and 1 Gravity fed pump. Have any of you all heard of Ventura(Germany) Centri-fugal pump?

I need more info on that pump...

Thanks.

Re: [fortune] How to breed kois ourself? [In reply to]	Can't Post

Well, Kelwin, call me John will do! LOL Cool

I bought about 10 small kois(about 1 to 2 inch) few weeks ago...and put them in a small water storage tank to keep them...and then i put 1 pump, 1200L/H, pump the water up to 0.5ft high into a small plastic aquarium, and the water will flow up...then down like a small(or tiny Crazy

)waterfall AND the water flow is not really strong, just normal. And those 1 koi got sucked! died and then found 2 of them sticking on the pump's input!(the input is with some plastic "netting") luckily that i saw it, if not i'll have another "ikan masin"(called salted fish in Malay) Angelic

now they have grown to 3 to 4 inches! Wink

Oh...The Ventura pump, i think i've heard that b4, but i don't really know hows the pump! if it is from Germany, i think it'll be quite ok, i have 2 pumps from there too...very good, used for few years already! 1 Italy, used for 6 years!

Hi John and any new baby koi breeder..

I had one experienced on raising the baby koi 2 years b4, is better to use air pump rather than gravity pump when the baby still very small..... i got about 180 babies koi from 2 of my japanese blood line, after struggled my head on picking them i only got less than 20 of them which I consider "not bad" and i keep it for myself the rest i passed it to my friends. I was asking one of my local koi dealer, he told me that, is easy to raise the babies but most of them turn out to be "local" koi, as most them will either orange or white....

Hope you guys enjoy the breeding fun... is fun to see the babies grow up day by day really great!!

Bendict,

So that was 2 years ago. How are the koi doing now? Did they turn out to be nice quality koi due to their japanese parentage or are just local koi?

Re: [bendict] How to breed kois ourself? [In reply to]	Can't Post

I came here because My Koi did breed. Have 3 , 3 year old kio, One orange, one tangeine colored and one bright yellow. Never figured they would breed, it was just a garden pond...The fish were el cheepos just to see if they would live thru the winter here. They survived ft thick ice. Birds, cats and other critters!
They survived 2 winters and are on summer #3. They grew 5X there size and are now about 8 to 10 inches long.

Well my son and his friend were camping in the backyard and the friend took a head longer into it at 3 am. The damage the next day? The pump, the fountain and the attached boilogical filter were wrecked ( but repairable) but what I saw when pulling my filter out was.....I have four new fish! They Appeared like majic!

WHAT THE HECK!!!!!???!!!

The 4 survivors are about a inch to a inch and a half long. And they are starting to show colors that are getting brighter each day. They are starting to surface to eat. One had a orange head and tail and a white strip in the middle. One is white with a bright yellow head. Two are being difficult to say what color might be there because they are being somewhat skittish still and will not surface slowly enough to feed and get a really good look!....

How do you breed? Have no clue mine just did!
