Abstract
The parasite fauna of blueback herring (Alosa aestivalis) and alewife (Alosa pseudoharengus) were examined to determine their usefulness as biological indicators in the differentiation of these two sympatric species. Thirteen parasite species were identified from 100 specimens each of blueback herring and alewife from the main estuary of the Miramichi River, New Brunswick, of which 11 and 8, respectively, represent new host records. Significant differences (p < 0.05) in the counts of Mazocraeoides sp., Diplostomum spathaceum (metacercaria), Derogenes varicus, Anisakis simplex (larvae), and Echinorhynchus gadi between alewives and blueback herring reflect differences of physiological and ecological order between these two host species.
