Abstract

Six species of helminth parasite were found on examination of intestines of 438 specimens of northern sand lance (Ammodytes dubius) from various areas of the Nova Scotia Banks. They were: Derogenes varicus, Brachyphallus crenatus, Lecithaster gibbosus, Bothriocephalus scorpii, Contracaecum aduncum, and a cestode (tetraphyllid) larva. Intensity of infestation was low and incidence low to moderate, with little difference between areas. Parasite species composition in A. dubius was similar to that of A. marinus, its European counterpart, but unlike that of A. americanus, the neighboring species to A. dubius in the northwest Atlantic.
