So I have a 2000 gal pond and this year my koi had a flock spawn. Because my pond is small and the new koi are mostly black I would like to remove them. I’m looking for ideas on how to catch them. There are about 15 fry. The only real option that I have thought of is to net and remove the adult koi then drain most of if not all the water to catch the fry. Don’t really want to do this because I don’t like the idea of doing a 100% water change and stressing out the adult koi by netting them and then acclimate them to the new pond water. I live in NY so this will be a spring time thing, that is if they survive the winter, just brain storming.
Thanks
