There is 2 times on the river calendar that walleye tend to go for cut baits.
In my experience the much dreaded post spawn walleye doldrums on the Red & other rivers of the Red River basin will produce walleye on Goldeye and cut or dead suckers.
From a silver dollar sized chunk of Goldeye, to a whole head of a large Goldeye, walleye that are steeped in the post spawn blues find them an easy meal after the exhausting rigors of spawning run.
The second situation is during the heat of summer when many shiner species, including Goldeye, Mooneye, and golden shiners, spawn on the fast cool waters of dams. Spawning fish die off due to stress from the spawn or heat stress and hungry sumo walleye seeking a bit of relief from the summers heat are more then willing to utilize the forage live or dead. You may find the rare and elusive Red River muskie looking to also take advantage of this situation for the same reason. Most of the large Red River muskie is caught in this time frame off the dams. DNR & NDG&F creel surveys have reinforced this trend with hard data.
I think the lesson we can pick up from this is a predator and the often thought scavenger species often share like habits. Catfish predatate far more often then they will scavenge, if conditions allow them to do so. A catfish has a great sense of smell and hearing, but poor eyesight, not well suited for predatory behavior under dirty water conditions. The same holds true with walleye, if conditions divert them from there normal feeding habits, such as dirty water and low visibility, a walleye is just as eager to scavenge to fill it’s needs.
A very interesting topic guys.
