Whitefish have experienced a population boom in the bay of Green Bay, while simultaneously declining in the main basin of Lake Michigan. This paradox is driven by different ecological conditions, as the nutrient-rich, shallower Green Bay provides food and better spawning habitats, whereas invasive mussels have caused a severe "nutrient desert" in the main Lake Michigan basin. Meanwhile, lake trout in Lake Michigan are experiencing a strong recovery, with healthy population abundances, increased wild reproduction, and successful management of invasive sea lampreys. While still heavily reliant on stocking, wild fish now make up a growing proportion of the population, particularly in the northern and mid-lake refuges. Charlie Henriksen, owner and founder of Henriksen Fisheries in Door County, will discuss why whitefish are proliferating in Green Bay and declining in Lake Michigan and why lake trout are experiencing a resurgence.
