I had an idea and was wondering if it could work.

I'd love to build a small pond for raising bait but that's just not going to be able to happen anytime soon right now. In the meanwhile I was trying to think of other ways I could raise FHMs.

One thought was to build a cage that is in my pond, maybe floating next to the dock or along the shoreline. If I made it 6x6' or 8x8' by two or three ft. deep, (big enough for a stack of 2 or 3 pallets, corralled it with 1/8in. mesh, and put a top over it, could this work? How small would I need to make the mesh to keep the young inside? Would 1/8" be too small and need to be something more like window screen?

Would this be a waste of time? If worth a try, how many minnows should I initially put in it? I assume I would be feeding them fish food.

My other idea was to use a small pool, about 8' diameter and 2 feet deep, put it in the shade, run aeration in it and see if minnows would work in that.
