Southern NJ host some large "crappie" ,  both black and white.   I  have caught crappie that have a yellow appearance too.   I have gotten then to over the 2 pound mark (one in photo to left).  This one actually hit a small streamer while doing some early spring bass fishing.  Hit quite deep too.  They fight well and if you can orient where they are you can catch lots of them.  Often the hits are very subtle.  Believe it or not I have gotten them on top-water flies too!
