We had an umbrella net suspended upside down several feet under the surface and fed gold fish over it all the time and then when we wanted to harvest some GF for river bait we would try to hoist the umbrella net up quickly, with a rope and pully hoist we had rigged up that hung out over the water, worked a little but the GF get too smart to get caught easily, one dip after feeding you would catch quite a few but not much on the second try, them things get extremely smart, probably the hardest fish to trick or catch.
