Parasites of Pacific Salmon, Oncorhynchus spp., from the Great Lakes,
By Patrick M. Muzzall
Journal of Great Lakes Research, Volume 21, Issue 2, 1995, Pages 248-256, ISSN 0380-1330, DOI: 10.1016/S0380-1330(95)71035-8.
A comparative summary of the literature on parasites reported from Pacific salmon, Oncorhynchus spp., from the Great Lakes is presented. Seventeen studies on parasites infecting Pacific salmon in these lakes have been published since 1955. Totals of 16 parasite species are reported from pink salmon, O. gorbuscha; 18 from coho salmon, O. kisutch; 24 from steelhead, O. mykiss; 22 from kokanee, O. nerka; and 19 from chinook salmon, O. tshawytscha. The majority of the parasites occur in the gastrointestinal tract. The acanthocephalan, Echinorhynchus salmonis, is the most common parasite infecting Pacific salmon, followed by the nematode, Cystidicola farionis. Thirty four (83%) of the 41 helminth species from Pacific salmon are represented by adults indicating that most species mature in their salmonid hosts. The dominance of these helminth species is attributable to the position of these salmonids in the food web as top predators in the Great Lakes.
