Description of dataset These data were generated in a large field experiment to investigate the effects of innovative and conventional hydropower turbines on fish. The data contain information on external and internal injuries of individual fish (Spreadsheet 1) and physical parameters for each net emptying interval (Spreadsheet 2). 2. File List: File 1 , Sheet 1: 2022-06-02 Raw Data.xlsx - Injuries File 1 , Sheet 1 Description: Fish ID numbers with scores for immediate (0h) and delayed vitality (96h) and all assessed external and internal injuries. Injury intensity is scaled from 0 = no injury to 5 = severe injury. See also Mueller et al. 2017 and 2020. File 1 , Sheet 2: 2022-06-02 Raw Data.xlsx - Abiotic parameters File 1 , Sheet 2 Description: Abiotic parameters for each net emptying interval (ID) and information on fish species, turbine type and treatment. Fish injuries averaged by emptying intervals. METHODOLOGICAL INFORMATION External and internal fish injuries caused by hydropower turbine passage were classified following the protocols published in M. Mueller, J. Pander, J. Geist, Evaluation of external fish injury caused by hydropower plants based on a novel field-based protocol. Fish. Manag. Ecol. 24, 240–255 (2017). M. Mueller, K. Sternecker, S. Milz, J. Geist, Assessing turbine passage effects on internal fish injury and delayed mortality using X-ray imaging. PeerJ 8, e9977 (2020). DATA-SPECIFIC INFORMATION FOR: 2022-06-02 Raw Data.xlsx 1.
