Development and testing of mechanistic fitness-based models to predict habitat choice, behavior, and recruitment of juvenile Chinook salmon in the Arctic-Yukon-Kuskokwim region

This data is part of the NPRB research project 1424. Specifically, these data describe varying prey capture success rates of juvenile Chinook salmon in response to our main variables of water velocity and dominance hierarchy. The complete dataset consists of six csv files. The data consists of 1. Single fish prey capture data from experiment using that used 2D measurements, 2. Single fish 2D microhabitat measurements from our experimental flume, 3. Single fish prey capture data from experiment using 3D measurements, 4. Dominance experiment data from prey capture trials recorded by an observer, 5. Dominance experiment 3D data extracted from the VidSync software, and 6. The lengths, mass, and days in captivity for our fish used in the dominance experiments. Juvenile fish were captured in the Chena River, Alaska, using minnow traps in 2015 and experiments were conducted beginning in January 2015 and ending in July 2015 when video analysis was completed. Chinook Salmon (Oncorhynchus tshawytscha) are a native salmonid to the region and a very popular fish for anglers. Over the past decade their populations have begun to decline due to a variety of factors including climate change, urbanization, and predation. Data are presented as three CSV files: Chinook_Dominance_Experiment_VidSync_Output.csv Chinook_Dominance_Experiment_LengthMass.csv Chinook_Dominance_Experiment_Behavior.csv本数据集隶属于NPRB研究项目1424。具体而言，其记录了幼年奇努克鲑（Chinook salmon）在水流速度与优势等级这两个核心变量影响下的捕食成功率变化情况。完整数据集包含6个CSV格式文件，分别为：1. 采用二维测量方案的单鱼捕食实验数据；2. 实验水槽中采集的单鱼二维微生境测量数据；3. 采用三维测量方案的单鱼捕食实验数据；4. 由观察员记录的捕食实验中的优势等级实验数据；5. 从VidSync软件中提取的优势等级实验三维数据；6. 优势等级实验所用幼鱼的体长、体重及圈养时长数据。本实验所用幼鱼于2015年通过小型诱捕笼采集自阿拉斯加州切纳河（Chena River），实验于2015年1月启动，至2015年7月视频分析完成时正式结束。奇努克鲑（Chinook Salmon，学名*Oncorhynchus tshawytscha*）是该区域的本土鲑科鱼类，同时也是深受垂钓爱好者青睐的鱼种。近十年来，受气候变化、城市化及捕食等多重因素影响，其种群数量已呈现下降趋势。本次公开的数据集包含以下3个CSV格式文件：Chinook_Dominance_Experiment_VidSync_Output.csv、Chinook_Dominance_Experiment_LengthMass.csv、Chinook_Dominance_Experiment_Behavior.csv
