Salmon age, sex, and length data from the Arctic, Yukon, and Kuskokwim regions of Alaska, 1960-2016
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...
