I agree with the trap methodology. However, I have also had good luck with waking at 3 AM, turning on the lights, and simply scoping the fish out. Particularly in cases where the fish ahd to be out NOW, not waiting for the fish to get hungry. The sudden lights on technique seems to "daze: the fish, and they stagger around "drunk". I have caught an fish with my ahnds with this method. However, I would try the trap first.
