Definitely need a round bucket with a good aerator and some sort of additive to the water helps a little, I use one called U2. They wont live in the livewell. I think they just stress out, the water will get bubbly on the top and once that happens they are done. I've been told that means the ammonia levels are too high, thay basically pee and poop themselves to death When that happens, just go catch some more and change the water. The other downside to using shad is that you and your rods will be covered in scales. They do work great though!
