I love to catch big crappie we were catching 2 1/2 lb crappie last weekend on 1/2 oz spinnerbaits man they are fun. The water temp was 69 deg and they all had eggs and the males were milting. As long as you start off slow with stocking and keep taking them out every year and stay on top of it you will be successful. Im not real familiar with the YP but I imagine they will help thin the numbers of small crappie down. All the places i fish with big crappie either have alot of shad or Golden shiners in the body of water.
