Parasites of Fish from the Great Lakes - Great Lakes Fishery ...

Table 3, continued.
Remarks: Guilford (1954) suggested Petromyzon marinus became infected when it ingested the infected
swim bladder of a coregonid fish; Black (1983) suggested that Cystidicola stigmatura is apparently absent
from the Great Lakes since 1925; the above record of Cystidicola stigmatura in Petromyzon marinus
maybe erroneous since Salvelinus spp. are the only hosts of it in North America (Black 1983).
