how to breed koi fish step by step (Step 2 separating the female koi)
You need to separate the female koi fish breeder from the males
Once the prospective parents have been identified, they need to be taken out of the main pond and isolated in separate and smaller ponds where they can be conditioned for spawning.
Males are separated from females to prevent indiscriminate spawning.
Many hobbyists start this isolation at least 1 month before the anticipated spawning date.
Eventually the female becomes rounder and noticeably bloated with eggs.
Now with a heavy but soft abdomen, she is presumed to be ready to lay eggs and is very carefully moved to the spawning pond.
This pregnant koi must always be supported by water during the move, even while inside a net.
At this point the male is also assumed to be ready to participate in the reproduction as well, and is moved into the spawning pond a few hours after the female has already been acclimatized to it.
Many breeders introduce the male in the evening, since spawning usually happens in the wee hours of the morning.
