I keep my jigging pretty simple for walleyes. I learned a lot by watching a flasher over time. Its very important to pay attention to what the fish want, and how they are reacting to what you are doing. The pause is just as important as the jigging many days. I have days where I cant hold still enough and I will set the rod down to watch the fish come up and strike. Other days the fish will keep chasing the jig around and could hit at any time. 95% of the time the fish will be under your jig and come up to attack your jig(what it appears like on the flasher). *Coming up* can be 6″, and it can be 5 feet depending on the mood of the fish that day.
I cant stress enough how important it is to have a couple different types of jigging spoons laying around, and switch up if the fish are showing up and wont bite. Some days it takes a heavier spoon to get that quicker drop and it will turn the fish on, other days the lighter, flutter type spoons will work better with the slower fall.
Keeping the jigging simple works best. Bounce the bait off the bottom once in a while, pull it up a foot and jig it 12″-18″ a few times.. let it pause, raise it a little and jig it again… pause, bounce it off the bottom. When I get a fish on the flasher, my jigging becomes more subtle, and I try to get the fish to come up to me, rather than drop down to it. When the fish starts to com up I pause the bait. If the fish comes up to it and doesnt hit it in a few seconds, I will jig it lightly once (just a few inches), then if it doesnt bite I will raise it slowly away, and jig slightly more agressivey if I make it a foot over the fish to try to get the fish to chase it further.
Its like a game of cat and mouse.
If you dont have a flasher, keep in mind constantly NOT to over jig your lure. A few pumps of the rod is all it takes, bounce the bait off the bottom once in a while, and be sure to pause frequently. Dont put the rod down and get burnt out on jigging. If a bait is stationary for too long, they fish will shy away from it most of the time unless it has a live minnow on it.
