Estimate of total Alaskan salmon abundance by region, 2000-2015

This dataset compiles salmon escapement data from Alaska Department of Fish and Game reports and salmon harvest data from commercial, personal use, sport fish, and subsistence sectors to generate an estimate of total salmon abundance in each of the regions defined by the State of Alaska's Salmon and People Project (SASAP). This dataset was assembled to enable a broad view of the salmon resource, whether biological (escapement) or economic/cultural (harvest), across regions. With that intent in mind, a fish is counted within a region if it escaped a fishery and was counted in a river that is contained within that region, or if it was caught in a fishery that is within the region. For commercial fisheries, each commercial fishing district was assigned to a region based on the location of the commercial fishing district relative to the bounding watersheds of the region. No effort was made to determine the region of origin for any commercially caught fish - thus for some regions, fish caught in one region may have been headed to spawn in another. This is especially true of Alaska Peninsula and Aleutian Islands commercial fishing areas, which are well known for having large amounts of Bristol Bay bound fish. Note that some regions have missing escapement data during some years. This dataset includes an R Markdown file which processes the original data and creates figures, the rendered html file generated from running the R Markdown file which includes many figures and data explanation, and several standalone versions of those figures.

本数据集汇编了来自阿拉斯加州渔猎部（Alaska Department of Fish and Game）报告的鲑鱼产卵逃逸亲体量（salmon escapement）数据，以及商业捕捞、个人自用、休闲垂钓及自给捕捞门类的鲑鱼捕捞数据，用于估算阿拉斯加州鲑鱼与人类项目（State of Alaska's Salmon and People Project, SASAP）划定的各区域内的鲑鱼总种群丰度。本数据集旨在全面呈现各区域的鲑鱼资源状况，涵盖生物学维度（逃逸亲体量）与经济、文化维度（捕捞量）。基于此目标，若某条鲑鱼成功逃过捕捞并在所属区域内的河流中被统计，或是在该区域内的捕捞作业中被捕获，则将其计入对应区域。针对商业捕捞作业，各商业捕捞区域依据其相对于所属区域流域边界的地理位置划归至对应区域。本数据集未对商业捕捞所得鲑鱼的原产地进行溯源，因此部分区域统计的捕捞鲑鱼，可能原本会前往其他区域产卵。阿拉斯加半岛与阿留申群岛的商业捕捞区域便是典型，该区域因汇集大量洄往布里斯托尔湾产卵的鲑鱼而闻名。请注意，部分区域在部分年份存在产卵逃逸亲体量数据缺失的情况。本数据集包含一份用于处理原始数据并生成可视化图表的R Markdown文件、一份由该文件运行后生成的包含多幅图表与数据说明的渲染HTML文件，以及上述图表的多个独立版本文件。数据来源：1. 珍妮特·克拉克（Jeanette Clark）与阿拉斯加州渔猎部商业渔业司、休闲渔业司、自给渔业司：《1995-2016年阿拉斯加州商业、自给、个人自用及休闲垂钓门类的鲑鱼捕捞量》，生物复杂性知识网络（Knowledge Network for Biocomplexity），DOI:10.5063/F1TT4P73；2. 安德鲁·门罗（Andrew Munro）、埃里克·沃尔克（Eric Volk），2018年：《阿拉斯加州太平洋鲑鱼产卵逃逸亲体量目标综述及2001-2009年逃逸亲体量回顾》，生物复杂性知识网络，DOI:10.5063/F1416VB4；3. 安德鲁·门罗、埃里克·沃尔克，2017年：《阿拉斯加州太平洋鲑鱼产卵逃逸亲体量目标综述及2007-2015年逃逸亲体量回顾》，生物复杂性知识网络，DOI:10.5063/F1GX48V4；4. 詹姆斯·萨弗里德（James Savereide），2017年：《1980-2016年库珀河年度奇努克鲑鱼产卵逃逸亲体量估算》，生物复杂性知识网络，DOI:10.5063/F1G15Z4D。
