Helminth parasites of redfish ( Sebastes fasciatus ) from the Scotian Shelf, Bay of Fundy, and eastern Gulf of Maine
Examination of alimentary tracts of 319 redfish (Sebastes fasciatus) from the Scotian Shelf, Bay of Fundy, and eastern Gulf of Maine yielded 13 helminth species: 7 Digenea, 3 Cestoda, 2 Nematoda, and 1 Acanthocephala. Total species composition was virtually identical with that found in the redfish o...
