Les parasites de l'éperlan d'amérique (Osmerus mordax) anadrome du Québec et leur utilité comme étiquettes biologiques

Abstract

Distribution of smelt parasites Glugea hertwigi, Diphyllobothrium sebago, and Echinorhynchus salmonis support previous hypotheses that three groups of anadromous smelt occur in Quebec waters. These groups are associated with three geographical areas: the Saguenay fjord, the south shore of the St. Lawrence estuary, and Chaleur Bay. Furthermore, the presence of two parasites almost exclusive to the smelt sampled in Forestville and Baie Comeau confirms the existence of a fourth group.
