on norfork about 20 years ago we used some nets that hung over the side About 3 feet wide and 6 or 7 feet long and made of fine mono. . They were weighted on the bottom end with a support rod on the top. They hung over the sides and every once in a while 3 or 4 of the circling mass would get stuck in the net. you would pull them up and toss them in the minnow bucket. We needed a few minnows to get started but soon had plenty of shad. Haven't seen any lately buy I bet somebody around the lake still has some. I would like a pair.
