How do Crappie spawn?

[NIMROD]

I posted a bunch of articles from In-Fisherman about the spawns, last week...Researchers have found Crappie in the South also spawn in the Fall, especially if Spring is messed up for them.
In the North after the spawns and rest period, the females start developing eggs again for the next year's spawn.

Farther south than us . I had a AGFC biologist tell me here if they don't spawn before water gets too warm the eggs would not hatch any way . Never saw matured eggs in Crappie in Arkansas except during the spring .
