Biological data were collected from Chinook Oncorhynchus tshawytscha and summer chum O. keta salmon along the United States portion of the Yukon River drainage in 2018. Age, sex, and length data were obtained from 4,774 Chinook and 5,907 summer chum salmon from commercial and subsistence harvests, test fisheries, and escapement projects. Samples were collected from salmon caught using gillnets, dip nets, fish wheels, beach seines, weir traps, and from hand-picked carcasses. Sex and length were recorded for nearly all salmon sampled. Ages were successfully estimated for 89% of the Chinook salmon and 93% of the summer chum salmon. This report provides a summary of the age, sex, and length data collected in 2018 for Chinook and summer chum salmon and is a single source document for historical summaries of long-term projects that collect age, sex, and length data from the Yukon Area. This report also provides a brief description of the Arctic-Yukon-Kuskokwim Database Management System (AYKDBMS) which is a publicly accessible online data archiving system that acts as an interface to query and download historical age, sex, and length data.
