on a private lake I once owned for a decade the BG would be on different spawning beds from april thru august and biologist I spoke with said crappie can do it different times of year and have seen black spawn different time than whites.

one lake in my home region they were done on all bigger lakes by mid may except one and we had the most incredible spawning run all the way thru first week in june. I was lucky enough to get the 411 on it and went several times thru that first week in june. but if some of the crappie guru's on here say they will do it thru most of year and they fish one heck of a lot more than I will believe it.
