koifish girl,
id agree that it doesnt matter if you just feed them the pellets.
ive held fish in nets, just fed on pellets where they cant sift the bottom and they spawn fine. i find lack of stress is the key if your feeding her ok.
picking em up and transporting them for a few hours seems to put em off sometimes.
i do know a guy that brings his perch right up to condition with prawns and yabbies and he reckons it improves his hatch rate but koi dont seem to be so needy. so a variety would be good but theres variety plenty in most pellets already.
definately keep em separated sex wise if you can, thatll stop the mass spawn and when your not expecting it, as well as i think the girls are never getting bothered when they dont need it..
also dont do water changes in the weeks leading up to a spawning unless you really have to. i reckon ive seen girls ripen up and just sit waiting from that. I moved them to spawn and they just ooooozed eggs.
change the water or fill your spawn tank, then pair em up and theyll go for it.
degree days hey steve, good call. you can get more than one spawning per season if you do things well.
