I was doing some duck hunting on a river today. We sailed a mallard and had to go retrieve it. I had to go back up a small feeder creek where the mallard went down. There is a warm water discharge back there and there were TONS of these fish......I mean THOUSANDS! I had my cast net with me in the boat. So, I made one cast and caught 6 of these big 'shad' looking things. They ranged anywhere from 8-12 inches. I don't know what they are. They kind of look like a small carp....but, they were shiney like shad. Does anyone know what these are and would they be good bait? Sorry for the picture quaility...it was taken with my camera phone. If I were to catch a bunch of these things, how do I keep them alive? I could put a tank with an aerator (sp?) in my basement. What would I feed them?
