✦ Synopsis

Abstract

Thiamine concentrations were monitored in various organisms ranging from plankton to fish in the Lake Ontario ecosystem. The low concentrations found in most samples indicated thiamine levels were not strongly influenced by the trophic status of an organism. A similar conclusion was indicated from data reported by other studies in freshwater and marine ecosystems. Thiamine is produced by microbes and microalgae, and is acquired by higher trophic level organisms through the diet. The issue of thiamine deficiency in wild fish was also examined. It was concluded that increased dietary consumption of prey containing thiaminase was an important factor that can reduce thiamine levels in higher trophic level species.
