INPFC/NPAFC High-seas salmonid tag-recovery database, 1956 - 2013

This data set contains information on the high-seas tag recovery program for salmon and steelhead from the 1950s to 2013 in the North Pacific Ocean, Gulf of Alaska, and Bering Sea, from the North Pacific Anadromous Fish Commission. The database was last updated in April of 2016, and this version was provided in November of 2016. Data are provided on the location, species, age, sex, and initial tag location. Annual high seas salmon recovery information have been reported annually to the International North Pacific Fisheries Commission (1981–1992) and to the North Pacific Anadromous Fish Commission (1993–present). The tag recovery program enables the investigation of ocean distribution, migration, and growth of salmon at sea. Here, only information from non-electronic tags are reported. Information are available for salmon species: chinook (Oncorhynchus tshawytscha), chum (Oncorhynchus keta), coho (Oncorhynchus kisutch), pink (Oncorhynchus gorbuscha), sockeye (Oncorhynchus nerka), and steelhead (Oncorhynchus mykiss). Researchers using these data are cautioned to possible biases in the data caused from non-random area of tag release and from recovery of tagged fish in coastal areas that may not reflect the basin or area of origin. A discussion of these issues is provided in Myers et al. (1996). Included maps are generated from the dataset and show the release month by species, and the recovery region at release point. These maps were created by researchers at the National Center for Ecological Analysis and Synthesis.

本数据集由北太平洋溯河鱼类委员会（North Pacific Anadromous Fish Commission）提供，涵盖1950年至2013年间北太平洋、阿拉斯加湾及白令海海域的鲑鱼与硬头鳟（steelhead）公海标记回收项目相关信息。该数据库最后一次更新于2016年4月，本次发布的版本源自2016年11月。数据集包含标记回收地点、物种、年龄、性别以及初始标记位置等核心信息。

年度公海鲑鱼回收数据曾于1981年至1992年间报送至国际北太平洋渔业委员会（International North Pacific Fisheries Commission），自1993年起改由北太平洋溯河鱼类委员会统筹接收。此项标记回收项目可为鲑鱼的海洋分布、洄游路径及海上生长状况研究提供关键支撑，本次公开的数据仅包含非电子标记相关记录。

本数据集收录的鲑鱼物种包括：奇努克鲑（Oncorhynchus tshawytscha）、狗鲑（Oncorhynchus keta）、银鲑（Oncorhynchus kisutch）、粉鲑（Oncorhynchus gorbuscha）、红鲑（Oncorhynchus nerka）以及硬头鳟（Oncorhynchus mykiss）。

使用本数据集的研究人员需留意数据潜在偏差：其标记放流区域并非随机选取，且标记回收多集中于近岸海域，无法完整反映鱼类的起源种群或原产地范围。相关偏差问题的详细讨论可参考Myers等人1996年发表的研究成果。

本数据集附带由美国国家生态分析与合成中心（National Center for Ecological Analysis and Synthesis）研究人员生成的配套可视化地图，可展示按物种分类的标记放流月份分布，以及各放流点对应的回收区域情况。
