Project Details

Early mortality syndrome (EMS) of Great Lakes salmonid species is a result of a deficiency in the vitamin thiamine. The goal of this research was twofold: 1) to provide fishery management agencies with information for management of forage fish, such as alewife, to minimize thiamine-related loss of lake trout, coho, and Chinook salmon; and 2) to determine if neurological and other abnormalities in thiamine-deficient fry contribute to the observed recruitment failure in Lake Michigan lake trout populations.
