There is a little 65cm Dainichi in there as well to add just a little competition. He hasn’t the staying power of the Sekiguchi male but does his best t keep up.

amazes me that you can take fish out of their pond and put them in a small vat and then they will spawn!
I would have thought the stress of everything would put spawning right to the back of their minds.
Good luck anyway

Vat is set up immediately adjacent to the pond so it’s net and then lift and drop them in. Eggs started flowing at 7am so we are in play. Just now a question of some water management as it will be a good few hours before she is finished.

Rule number 1 for me is that cover stays on the vat whilst they are actively spawning; whilst there is a good 9in of freeboard in there the little Dainichi could so easily get flipped out, its pretty brutal at the moment and when the lass is penned between the males and decides she wants to move then she just barges them out the way.. 20kg of lady trumps 4kg male every day of the week.
I will however throw the Gopro in just for you.

Hope it goes well for you Dave.
I watched a video from Matt the fiberglasser who said Dave had the best koi pond he had ever seen,didn't realise it was you Dave,and you have some truly stunning koi all grown from around 6ins.
That is the way I like to do it,full credit to you.John

Sounds good Dave,
Can I ask,when you move the koi to the tank is that dechlorinated from the tap and do you raise the temp higher than the pond to get them going?
Would love a step by step procedureJohn

I simply fill a vat with pond water, with the possibility that it could take a couple of nights to get success I have a small pump constantly recirculating water from the pond through the vat. This keeps the water in the vat up to temp and more importantly keeps the massive build up of Ammonia in the vat under control. Even in a large 2.8m vat we peaked at 1ppm Ammonia with the recirculation, without it I would have had to abandon.
The brushes get the female going, added to this the males nuzzle her flanks with the rough skin on their cheeks (those seasonal turbicles are there for a reason!).
Judging when the action is finished is the hard one, you don't really want to return the female to the pond if she hasn't finished but there is always a balance.
After the spawning has finished I move the brushes into the hatching tanks That way they are in water that is clear from any parasites that may have been free swimming in the pond water. If you were hatching them in the spawning vat then the recirculating method isn't ideal but it can be done. For sure when spawning has completed you don't want to carry on recirculating pond water as you can get all sorts of issues both with pond and vat.
I have isolated the vat, there are a few hundred thousand eggs in there that missed the brushes, I will see if I can hatch these out.. It spreads risk.. I added methylene blue at 2ppm to the vat this evening, this will help avoid the build up of fungus on eggs in there and at this dose rate is a pretty effective parasite treatment. Over the next few days I will exchange a load of water in the vat to dissolve out the MB and the ammonia in there.
The brushes that I moved into the hatching tanks have had a dose of malachite added, its an alternate to MB and does the same job but doesn't whack the bio filters quite so hard..
It is all straightforward, just a question of planning and covering the bases and trying to spread the risk.
The one thing that has always to be accepted is that there is a real risk of casualties with the fish, this is the case with any spawning, it puts a big strain on the Koi and you need to go into it with this in mind.

Great explanation Dave. Would nt have guessed that you would have treat the egg spawn with a parasite
Treatment.
Awesome.

Thanks Dave,very informative and good luck with the hatchlings.
It would be nice to keep in touch with the egg progress,hatching and selection.John

really interesting Dave.
I have always wondered if perhaps there isnt a grand champion in every spawning, maybe not even in the variety your chasing because they throw all sorts dont they ?, but finding that one special fish must be like finding a needle in a haystack.
How many from the hundreds of thousands is it possible to even raise to a size where what they might become is recognisable?.
I love this topic, very interesting, and id love to try it myself, but there seems to be loads and loads of planning and pitfalls.
I do actually have some nice adult fish I could try it with, but I feel like theres so much I just haven't got a clue about …..suppose the best way to learn is to try though !
Hats off to you.
David
Every day feeding container?
Good shout, I'll have a look at Takazumi :)
