Environmental Science and Ecology graduate students Jonathan Truscott and Caleb Geister, Research Associate Dr. Matt Futia, and faculty member Dr. Jacques Rinchard presented research at the joint conference of the International Association for Great Lakes Research and the Society of Canadian Aquatic Sciences, held in Winnipeg last week.
Truscott presented findings on the relationship between thiamine deficiency and maternal provisioning in Great Lakes lake whitefish. Geister shared research using fatty acid analyses to estimate lake trout diets in Lakes Ontario and Superior.
Futia presented research examining differences in diet patterns between naturally produced and hatchery-produced lake trout across life stages. Rinchard also presented a poster on lipid and fatty acid signatures of cisco eggs from wild and domesticated broodstock.
Both Truscott and Geister conduct their graduate research under the advisement of Rinchard.
The conference brought together researchers, students, and professionals from across North America to share advances in aquatic sciences, fisheries management, and Great Lakes research.
