Crazy warm water and shallow south jersey lakes = early prespawn crappies!
I like to split crappie spawn into a few phases, the early prespawn is when they start moving and migrating out of the deep holes. you will see them active near drop offs. The bites are there but it's either slow bites or if they nip/short strike.
Prespawn is when they are actively feeding, casting anything will get them. Even big bass lures!
Spawn is when they are actually in bed... doing their thang... we can talk about this later because now it is the early prespawn phase and that means the best way to catch them is with a float! suspend a small jig like I am and get em by the tons! i think i have gotten over 50 this session with my home made skirt jig!
