I hope to see some of the experts chime in on this one. As a personal opinon I would make sure you get some good forage fish established first. Something along the lines of fathead minnows. What I have read on crappie I would think there would have to be ample enough forage for them in the muddy water to be able to find it. A good pellet trained bluegill would be my choice. I would install a feeder on a timer. I have hybrid bluegill right now that the second the pellets hit the water they are there. I have just a handful of them to see how well they do compaired to my native BG of the same size I stocked at the same time. The hybrid are a lot more aggressive at feeding time than are the natives. The only downfall I see is that they may revert back to GS and Gs do well in turbide water. I have read if you go hybrid BG that it is a good idea to kill off the pond around every 5 years in order to keep from establishing a green sunfish population. It sounds like a kill off may be natural in your pond. These are only my opinions and I am no expert. These are just my personal opinions based on what I have read and also information I have picked up here in past threads. Good luck.
