Hi,
Yes, RES and shellcracker are the same. The Georgia record for shellcracker/redear is larger than the bluegill. Shellcracker doesn't spawn as often as the bluegill, but even though they don't eat feed they do seem to grow larger then the bluegill, but at a slower rate. We recommend 20% shellcracker to the amount of bluegill you put. If you are going to feed, then 800 bluegill and 200 shellcracker would be our recommendation for your pond. However, if your main goal is to have big bass and no interest in catching bream, then add all bluegill they reproduce more offsprings for your bass.
