A Desktop Approach to Assessing Lake Whitefish Stocking Feasibility

Background Lake whitefish (Coregonus clupeaformis) numbers are declining substantially in the Great Lakes, concerning fishery managers and the commercial and tribal fishers who highly value the species. The public increasingly shares this concern due to media coverage that illuminates fishery stressors and recovery prospects. This edition of Research Notes highlights recent research contributions on lake whitefish supported by the Great Lakes Fishery Trust. In 2019, a team from the Michigan State University Quantitative Fisheries Center evaluated the feasibility of stocking lake whitefish to rehabilitate or supplement the Great Lakes fisheries. James Bence, Travis Brenden, and Emily Liljestrand, as research team…

New Study Shows Pacific Salmon Transfer Contaminants to Resident Fish

Dominic Chaloner, a research associate professor at the University of Notre Dame, led a team of scientists to assess the extent to which Pacific salmon migrating from the Great Lakes into tributaries during their spawning runs increase contaminant levels in local fish populations. The team focused on mercury and persistent organic pollutants (POPs) such as polychlorinated biphenyls (PCBs), given their prevalence in the Great Lakes Basin.

New Vessel Fills Great Lakes Research Niche

The 69-year-old research vessel (R/V) Chinook was fast approaching retirement. After years of generating valuable research data on the Great Lakes fishery for the Michigan Department of Natural Resources (MDNR), it was nearing the end of its useful life. Enter the R/V Tanner, a state-of-the-art 57-foot aluminum-hulled vessel with all the modern equipment its crew could hope for. This new member of the fleet, named after former MDNR Fisheries Division chief and director Dr. Howard A. Tanner, was funded in part by a grant from the Great Lakes Fishery Trust (GLFT). Although the Chinook will be missed, the Tanner is…

New Method Available for Estimating Relative Recruitment Levels

Thanks to a recent GLFT project, fisheries managers now have two computer models, developed by a team of researchers who wondered if they could find a better way to determine relative recruitments of spawning populations in a mixed environment. The researchers maintained that if they could identify that certain vulnerable populations contributing individuals to a mixture had declining recruitment levels, then fisheries managers could better employ appropriate conservation measures.
