I've heard somewhere (very long time ago - when I was still gullable).... that these purplish colour lighting (Aqualux) makes your fish sterile.... If that is true, I think that might be a good idea...
i think that adding a predator is the only way. what about an arapaima if your ponds are huge. but they might eat you lol. and at 2m long they might be a tad too big. what about adding loads of dragonfly larvae, they should eat baby fish. although they might be eaten by the adult fish.

that would be good it would create natural selection, also you wouldn't have too many dragon flies.
I agree with above, but how did all this start anyway?
