I don't ice fish the way I used to. I spend more time chasing fish on the soft water side in barely "open" water. But once I lock down enough open water trout or salmon to keep my streak going, I look forward to following the warm water fish as the move inshore when the ice wastes away. That's what I did on my last 5 trips, nearly 100% jigging. Starting out in 15-25 feet of water in early March, and following the fish into 5 feet of water on April 9, I had nearly non-stop action. In that shallow water, the fish were packed so tight I could swear I smelled them.
I have pretty strict standards for "non-stop" action, but 300 fish in those last handful trips gets me in the ballpark anyway. The usual warm water customers, with a few less commonly jigged species that may serve me well in the derby I'm fishing. By the end of the day on the waters I fish, walking in the corn ice has become more like trudging through beach sand, and I punched a boot or 2 through just for good measure, confirming it was time to move on.
