I didnt see your other post, so dont know how big your babies are ... Here's what works for us ...
If they are still in the half inch or under size, they may have a spot where they all like to hang out ... If they do, we have a flat, surface skimmer net ... just scoop them up and flick them (from the back side of the net) into a tote with some water in it ... If not, ours hang around the edges of the pond. Really hard to see, but if you are patient, you can snag them with a 4" fish tank net ... 3-4x a day will reduce them quickly ... as the sun is setting they tend to be easier to catch. While tiny, for us, it's the easiest time to catch them.
If they are over 1-3" the only thing that has worked for us is to get the big net out and drag the pond ... Anything that lives in our pond over 6" is friendly and a pain in the neck, so it becomes a three person job ... one to run the big net (it has "poles" on each end), one to use a normal net to catch the contained fish, and one to feed the bigger fish to keep them out of the way. We can get the bulk this way ... if you want ALL out, then drain the pond a bit ... Our main pond is 11x18 with 4-5' depth ...
If anyone has more suggestions, Im all ears too, as I have a few comets that need to go.
