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
