I am asked by many vacationers to the area in the summer months if the Bay of Green Bay freezes over. We as residents of the county witness this first hand. As the ice becomes safe for travel many anglers set out for the frozen basin.
The area has gained popularity for a species of fish that until recently was not sought after by ice anglers. The Lake Whitefish is used primarily as a staple for many of the iconic fish boils across the peninsula, but they have a very unique story to tell. Once numerous in Lake Michigan, the whitefish have sought refuge in the Bay of Green Bay. The reason for leaving the lake was due in part to the changes happening in that body of water. As invasive species increased the natural food supply for whitefish began to dwindle. As the whitefish began to seek new refuge they encountered another non-native species that would turn their misfortune into a winning situation. The round goby is a small fish that lives in the rocky bottom of Green Bay. The whitefish have capitalized on this situation and are gorging themselves on this invasive.
So next time you hear me or Gary Nault talking about whitefish, you will have a greater appreciation for this fish and its benefit to the Door Peninsula.
