Helminth parasites of the alimentary tract of Atlantic halibut ( Hippoglossus hippoglossus L.) and Greenland halibut ( Reinhardtius hippoglossoides (Walbaum)) on the Scotian Shelf
Examination of the alimentary tracts of 272 Atlantic halibut (Hippoglossus hippoglossus (L.)) and 71 Greenland halibut (Reinhardtius hippoglossoides (Walbaum)) from the Scotian Shelf yielded a total of 25 helminth parasite species, 23 from H. hippoglossus (16 Digenea, 3 Cestoda, 2 Acanthocephala, 2...
