Mike! You just solved my problem! I want to cull two or three koi out of the pond, and simply cannot catch them. They are afraid of the net, because when they feed, I jam it down fast into the water trying to catch them, but of course never do. And when I leave the net in the water, to try to get them used to it, they just stay away.
Now I understand that I can train them to come INTO the net, by using food. I'm going to work on that. I have a lady who wants to take my culls, as soon as I manage to catch them.
