Aaron Heisey ’22 and Dr. Jacques Rinchard published an article in Journal of Great Lakes Research that explores factors influencing egg thiamine concentrations of Lake Ontario lake trout.
This paper, originating from Aaron’s MS thesis, explores factors influencing egg thiamine concentrations of Lake Ontario lake trout. The results of this study suggest that morphotypic differences in the feeding ecology of lake trout can result in biochemical changes, with Lake Superior deepwater morphotype (relying on benthic prey) producing egg with significant higher amount of thiamine compared to the lean morphotype (such as Seneca and Lake Champlain domestic strains relying on pelagic prey). These differences may therefore influence effectiveness of lake trout restoration efforts.
Aaron is now a fish biologist at the US Geological Survey Eastern Ecological Center at the S.O. Conte Anadromous Fish Research Center in Massachusetts.
