I caught a few dozen 3" shad last night with my 7' x 3/8" cast net. , they lived about an hour in my engle bait keeper.
3/8" net mesh is too big for 3" shad, about half of them were half in and half out of the mesh, very difficult to remove, killed several of them just pushing them out of the mesh.
Fished with the shad for about an hour, no crappie. If I can figure out how to keep them alive, I'll buy a 1/4" mesh net.
