I was just watching walleye videos other night. The fella was giving seminars. He said the best times was 3-4 days prior to and 3-4 day after the full moon. But he said they will be doing there thing but.. You don't know exactly what time. So you just gotta put the time in. If I can remember the video I will tell ya they are very good. A 3 part series. I your using lures he also recomended using lures with silver type luminescent sides to help catch any light.
