Metazoan parasites of salmonids and coregonids from coastal Labrador
323 fish of six species (salmonids and coregonids) from four locations on the eastern coast of Labrador were examined for metazoan parasites, using conventional parasitological techniques. -- Twenty-four genera of parasites were recovered (3 of Monogenea, 8 of Digenea, 5 of Cestoda, 5 of Nematoda, 1...
