I bucketed probably near a thousand leopard frog tadpoles from the sitting water in my half dug pond early this summer. For the heck of it the kids and I took them home and put them in a smaller aquarium next to the larger aquarium with the bass, catfish, gar, etc. in it. I would occasionally throw in a couple small net fulls and they were nailed immediately.
I've been told that bass don't like the taste of tadpoles. Obviously, that opinion was way off.
