This may be an option for crappie as well depending on how many you plan to harvest and how fast you they grow and what size you need them.

LMB also give you plenty of food in my opinion even at 8-10 inches if you like to eat them.

This is pretty much what my pond has turned into now, as I will struggle to grow fish to large size due to my stocking method I followed from the fish truck, unless I am willing to start over and that is not an option at this point.
