Mike Lowe of USGS presents his findings of what reefs contribute to the current lake whitefish fishery around Buffalo Reef, Lake Superior. By looking at differences between historical spawning sites and those used today, he creates comparisons of habitat quality and questions prey availability.
Movement and habitat use of ciscoes in Lake Erie and northern Lake Huron
Todd Hayden (Michigan State University) describes the seasonal movements and habitat use of the shorthead cisco in the Les Cheneaux Islands of Lake Huron. Joseph Schmitt (USGS) presents on behalf of Richard Kraus on the movement, habitat use, and survival of hatchery-reared ciscoes in Lake Erie.

When Good Planning Meets Opportunity: The Story of the Epic 2022 Coregonid Year-Class in Lake Superior
Listen to Dan Yule (USGS) talk about the comprehensive sampling strategies implored during 2022 that led to finding a historic year class of coregonids in Lake Superior. Novel genomic analyses were used to identify larval and age-0 coregonids, overcoming longstanding...
Exposure to UV radiation induces hatching and alters growth and development of coregonine eggs
Ph. D candidate Nicole Berry of Miami University – Ohio takes us into a glimpse of her doctoral dissertation research on the potential effects of ultraviolet radiation on coregonine eggs and larvae.
A Reassessment of Historical Cisco Declines in Green Bay, Lake Michigan, and Saginaw Bay, Lake Huron
Ben Rook of the Michigan DNR presents his research on historical cisco populations, highlighting the effects of overfishing, rainbow smelt, and bottom hypoxia in the bays and upper Great Lakes. Here he gives estimates of abundance during the Late 1940s and Early...
One of these things is not like the other! Lab & field observations for Lake Whitefish and Cisco
Kelly Hoyer, a Ph. D candidate at Central Michigan University, talks about her work on larval Lake Whitefish and Cisco. She compares the two species and their interactions with various predators and how the two fish differ....
