Sockeye salmon brood tables, Upper Cook Inlet, Alaska, 1968-2016

Brood tables, also called run reconstructions, utilize annual estimates of the total run (commercial catch plus escapement), and samples of ages, to estimate the number of recruits per age class. These data are useful for salmon biologists to understand salmon productivity and salmon life histories. This dataset consists of original brood tables for sockeye salmon from the Kenai and Kasilof Rivers of the Upper Cook Inlet in excel format, R scripts that slightly reformat the dataset into a format consistent with other brood tables collected as part of the State of Alaskan Salmon and People project (https://alaskasalmonandpeople.org/), and the reformatted tables as a .csv file. Age classes are given in European Notation, where the first number is the number of winters spent in freshwater before going to sea (1 winter in freshwater = age-1.X), and the second number is the number of winters spent at sea (3 winters at sea = age-X.3).

亲代数据表（brood tables）又称洄游量重建（run reconstructions），其基于总洄游量（商业捕捞量与产卵亲体逃逸量之和）的年度估算值与年龄样本，估算各年龄组的补充个体数。此类数据可为鲑鱼生物学家探究鲑鱼生产力与生活史特征提供有效支撑。本数据集包含源自库克湾上游基奈河与卡西洛夫河的红大麻哈鱼（sockeye salmon）原始亲代数据表（Excel格式）、用于将数据集小幅重格式化以匹配阿拉斯加鲑鱼与人类项目（State of Alaskan Salmon and People，https://alaskasalmonandpeople.org/）所收集的其他亲代数据表格式的R脚本（R scripts），以及重格式化后的逗号分隔值（.csv）格式数据表。年龄组采用欧洲记法（European Notation）标注：第一位数字代表入海洄游前在淡水环境中的越冬次数（淡水越冬1次=年龄-1.X），第二位数字代表海洋阶段的越冬次数（海洋越冬3次=年龄-X.3）。
