North Pacific salmon abundance, 1925-2015

Abundance estimates of wild and hatchery Pacific salmon Oncorhynchus spp. are important for evaluation of stock status and density-dependent interactions at sea. This data package includes total abundances of pink, chum, and sockeye salmon, reconstructed from catch and spawning abundance data for both Asia and North America. These data are in two main categories of salmon abundance estimates: (1) return (catch plus escapement) estimates of natural-origin and enhanced-origin salmon (numerical and biomass) by species and region, and (2) Total biomass estimates of mature and younger salmon by species and region (natural-origin and hatchery-origin combined). Most of the tables cover the period from 1952-2015. Longterm tables begin at 1925. The .csv files are plain text versions of the tables found in the original excel file. The excel file also contains additional information on how the datasets can be used. These data are described further in: Ruggerone, G.T., Peterman, R.M., Dorner, B., Myers, K.W. (2010). Magnitude and trends in abundance of hatchery and wild pink salmon, chum salmon, and sockeye salmon in the North Pacific Ocean. Marine and Coastal Fisheries: Dynamics, Management, and Ecosystem Science 2:306–328 (available at http://www.bioone.org/doi/full/10.1577/C09-054.1). They are also included as Supporting Information in Ruggerone, G.T. & Irvine, J.R. (2018). Numbers and Biomass of Natural- and Hatchery-Origin Pink Salmon, Chum Salmon, and Sockeye Salmon in the North Pacific Ocean, 1925–2015. Marine and Coastal Fisheries: Dynamics, Management, and Ecosystem Science 10:152–168 (available at https://onlinelibrary.wiley.com/doi/full/10.1002/mcf2.10023). The dataset here is the same version as in the SI of Ruggerone & Irvine 2018, in the form of extracted .csv's.

野生与孵化场繁育的太平洋鲑属（Oncorhynchus spp.）资源丰度评估，对评估种群现状及海上密度依赖型相互作用具有重要意义。本数据包涵盖粉鲑、大麻哈鱼与红大麻哈鱼的总资源丰度数据，这些数据通过整合亚洲及北美地区的捕捞量与产卵种群丰度数据重建得到。

本数据集包含两类核心鲑鱼资源丰度估算结果：
1. 按物种与区域划分的自然起源与孵化场起源鲑鱼的洄游总量（捕捞量+逃逸量）丰度估算（含数量与生物量两类指标）；
2. 按物种与区域划分的成熟及幼年鲑鱼总生物量估算（自然起源与孵化场起源合并统计）。

多数表格的数据覆盖时段为1952年至2015年，长期时间序列表格的起始年份为1925年。本数据集的.csv文件为原Excel文件中表格的纯文本版本，原Excel文件还补充说明了数据集的使用方法。
