"The electro fishing doesn't kill the fish correct? So as long as I leave them in the water they'll be fine for the most part and simply remove the crappie to kill them correct?"
For the vast majority of fish, no, it does not kill them. It just stuns them and they revive. I have heard that maybe trout don't do well with it though.
Regarding the crappie, eat them or toss them on the bank, IMO.
