The males will move in before the females even leave deep water haunts.

A couple of years ago, a buddy and I were longlining on Ky Lake . We knew the black crappie had been moving towards the banks but that day, we only had 1 keeper for 2-3 hours fishing. I told my buddy they had to be close by so we went to a shallow bar that had 9 feet along the edges and dropped off into 15 feet. The very top of the bar had 5 feet of water. On our first pass, we had 4 poles go down at one time. Every one of the fish were cookie-cutter 12 " male black crappie. This spot was no more than 20 yards across and no more than 20 yards off the rocky bank. We would troll about 40 yards one way, turn around and troll back the same amount. We had to defend our spot as there were others who tried to move in and anchor on it when they could see we were there first, knowing they would end our trolling passes. I let them know real quick I wasn't going to tolerate that so they left. We had forgotten to keep the clicker going for each fish we caught so we knew we were getting close to a double limit. When we got to the ramp and counted, we had 39 crappie. Each was a duplicate of the others and every one black males. We had taken 38 keepers in 5 feet of water near the rocky bank in an hour.

The next day my buddy fished the same spot and caught zero. My Dad and I fished it later that week, nothing. They were stacked on that one spot for that short time we were there. Haven't been that lucky in a single spot since.
