Small scale abundance and movement of Atka mackerel and other Steller sea lion groundfish prey in the Western Aleutian Islands

The dataset was collected in the central and western Aleutian Islands, Alaska during 2014 and 2015 as part of a large-scale tagging effort to estimate Atka mackerel abundance and movement at several locales. The dataset describes locations and lengths of tagged fish as well as conductivity, salinity, and temperature data. The dataset consists of 9 files: 1305_TagsRecovered.csv 1305_TagsReleased.csv 1305_Specimen.csv 1305_SeededTags.csv 1305_Mortality.csv 1305_MasterHaul.csv 1305_Lengths.csv 1305_CTD.csv 1305_Catch.csv

本数据集于2014至2015年间在阿拉斯加州阿留申群岛中西部采集，作为一项大规模鱼类标记研究的组成部分，旨在估算多个采样位点处阿特卡鲭（Atka mackerel）的种群丰度与移动规律。本数据集记录了标记鱼类的采样位置与体长数据，同时包含电导率、盐度及温度观测数据。本数据集共计包含9个数据文件，分别为：1305_TagsRecovered.csv、1305_TagsReleased.csv、1305_Specimen.csv、1305_SeededTags.csv、1305_Mortality.csv、1305_MasterHaul.csv、1305_Lengths.csv、1305_CTD.csv、1305_Catch.csv
