Abstract
Our recent experimental work and ecoepizootiological assessments provide mechanistic data supporting a plausible hypothesis for an association between a prey base comprised of a large biomass of nonnative alewives Alosa pseudoharengus and the recruitment difficulties currently experienced by Great Lakes salmonines. We hypothesize that the thiamine deficiency induced by alewives, a species harboring high thiaminase activity, represents an ongoing cause of fry and adult mortality in salmonines. Overall ramifications of the thiamine deficiency on recruitment have not been firmly established but may represent a substantial bottleneck for natural recruitment in feral salmonine populations in the Great Lakes.
