Alaska Salmon Contaminants Study Date Posted: August 22, 2001 Contaminantsﾒ specialists from the Fairbanks, Alaska office will be conducting a contaminant study on fish species used for subsistence purposes. The study will focus on chinook (Oncorynchus tshawytscha) and chum (Oncorynchus keta) salmon from the Yukon and Kuskokwim rivers. Both species are important subsistence foods and both species are declining in the Yukon River. The goal of the study is to collect information on a large number of contaminants including metals and pesticides that can be used as a basis of comparison (baseline) for future studies. Another cooperator will be examining fish for infection of Ichthyophonus hofferi, a parasite of chinook salmon which threatens Yukon River salmon.
