Late ice is a very good time to catch monster Pike. Pike will make their way back to the shallows. First, they will stage (stop) on the base of the drop-offs into the shallow / mid-depth bays until it has warmed up enough for them to feed in the shallows. Once the fish have moved up, look for old weeds. These old weeds provide cover for the northern when they are hunting.
Start your search along the base of drop-offs, humps, or shoreline points. Search along the break lines of these structures. Some key areas to focus on, are inside turns, steep inclines transitioning to gentle slopes, and transitions from hard to soft bottom. These areas will congregate fish. If no fish are there, make your way into the shallow and mid depth flats. Look for weed lines, small break lines, or rock piles.
Why It is important to focus your efforts on those micro transitions mentioned above (weed lines, soft to hard bottom, inside turns) because these not only act as congregating points, but fish use them as highways to move from spot to spot.
During this time of the year, the Northern Pike goes into scavenger mode. This means that they will roam the bottom for fish that have died during the winter. Think of them as the garbage truck of the lake.
Tactic With ice fishing, it is important to drill a lot of holes and to keep moving, or cover as many different areas as possible. For example, have holes on the shallow flats of the bay, on the mid-depth weed lines, and at the base of the drop-off.
Since the Pike are roaming the bottom for easy meals, it is important to mimic that action. Using a tip up with a large dead bait usually gets the biggest fish of the season. Use a predator rig and a large dead bait and sit back. That being said, people still enjoy jigging for these monsters. Use a large spoon or jig.
