I assume you mean feeding them artificial food i.e. pellets.
Yes, there are a few of us that have experimented with feeding or raising crappie with fish food. I am pretty sure that black crappie were primarily used. It has been discussed with a fair amount of detail in a couple of previous posts. Using the search feature in all the headings should locate the desired discussions. Cecil has probably the most experience with pellet feeding crappie. Bottom line, it is difficult to consistantly get them started on feed and to keep them healthy while confined. I'm not sure if there is any information here or elsewhere about how many or what percentage of the feed trained crappie will remain eating pellets when they are released into the open pond setting. Not a lot of people or hatcheries do it because of the difficulty and problems involved. I think it would be very, very difficult to train very many crappie to eat fish food when the subadult or adult crappie are free ranging in an open pond.
For more info and as a start, A search using the words - crappie pellets will bring up related discussions in the headings (Forums) of: Questions & Obs., Types of Fish to Choose, Corrrective Stocking, Feeding, and Help.
