Hi

Has anyone tried breeding koi in aquaponics?
If so, any tips on how to get this going?

Planning on eventually setting it up in a 3000L plastic tank. Maybe 4000...


Cheers

Mine arent old enough to breed, but I still have quite a few in there.
Dont you use a spawning mop to breed them?
I cant see why you couldnt

I think the Koi breeders put the female in a separate spawning pool with a few males when she is in season, around spring and then remove the parents afterwards as they eat their eggs. cheers Steve

Yeh I've heard of that too...
So i can keep a bunch of koi in the aquaponics pond until they show signs of breeding then i'll move the female and a few males to a separate pond and wait for the magic to happen.

Yep thats the best way if you want to breed them. Not exactly sure how big or mature they have to be but i would assume a reasonable size and age. Koi can get to over a meter and live many decades so i'd think around the foot mark.

hi guys,koi are good to breed around three years old although some breed sooner and later,but be careful they should have enough room for the males to chase the females so she can spread her eggs out nicely and in turn the males should be able to fertilize the eggs properly,if they're too confined the females eggs can clump abit too much and you can end up with mongrels and more deformaties. alot of the members that breed koi in the wa koi society use spawning brushes,but you can use different items, i have used mops , nylon rope cut a little to unwind into strands hanging off the main line ,even shade cloth cut into strips almost all the way down and then weighted down with the strips resembling reeds floating vertically.

if you can do a breeding pond about 3 to 4 mtrs long x about 1.5 to 2 mtrs wide and around 400 to 500 deep,that should do you fine enough,not too deep because then the female has too much room too get away,resulting in less success. in saying all this ,i'm not a pro,but it has worked for me most times.

thanks for reading ,just thought my little bit could help,
cheers,

Thanks for the info mate! Much appreciated.
Will give it a bit more thought before getting into this!
Do you think a 3000 or 4000 litre circular plastic fish tank is appropriate for this? Ratehr than constructing ponds... im thinking of having two of these (one for the aquaponics and the other for spawning and growing out fish in...)
