I've seen much discussion and cussin' of crappie on here, but I don't recall seeing anything about how and where they spawn. I'm sure it has been discussed, but I can't find it. Do they make beds like bass and bluegill? How deep do they spawn?

I got to thinking about this when I went to the pond today and saw a crappie right on the bank with its nose toward the shore. It couldn't have in more than a foot of water. It would stay there until it noticed me, then swim off. Within a minute it would come back to the same spot and stay pretty much motionless until it noticed me again. It sure wasn't interested in any lure I tried. This went on for about 15 minutes. Was it spawning or just being friendly? :p :p
