When anglers target walleye through the ice, they often experience different levels of activity as the day progresses. In early morning, around sunrise, the fish will be active, and you may want to use larger lures and more aggressive jigging. As time wears on, those fish will scale their intensity back – during that time you’ll want to select smaller lures.
When all activity seems to have dropped off, you’ll want to consider sitting tight and waiting for the fish to come to you. Then, as sunset nears, often their activity will pick up and you’ll want to revert to your early morning strategies.
