Salmon age, sex, and length data from Arctic-Yukon-Kuskokwim Region of Alaska, 1960-2017
Age, sex and length data provide population dynamics information that can indicate how populations trends occur and may be changing. These data can help researchers estimate population growth rates, age-class distribution and population demographics. Knowing population demographics, growth rates and...

Age, sex and length data provide population dynamics information that can indicate how populations trends occur and may be changing.

These data are therefore particularly important in valuable fisheries like the salmon fisheries of Alaska. This dataset includes age, sex and length data compiled from annual sampling of commercial and subsistence salmon harvests and research projects in the Arctic-Yukon-Kuskokwim region of Alaska.
