I have a buddy that is a good crappie fisherman and he has been showing me the ropes the last couple of years. We fish quite a bit in December and do pretty good. One day the fish bite like crazy and the next day they wont, so my question is what influences this the most? In late December the fish are in their winter pattern so conditions are pretty stable from day to day, but it seems like crappie move around often and it is hit or miss. Any reason for this?
