Behavioural response of downstream migrating European eel (Anguilla anguilla) to electric fields under static and flowing water conditions. Ecological Engineering, 172, p.106397. DOI:10.1016/j.ecoleng.2021.106397 This ReadMe file describes the Data file accompanying the above publication. The dataset contains: 1. Tab 1 "Experiment 1- Static Water". Contains the data recorded during the static water tests. Sheet includes infomation on eelID, waveform, threshold field strengths for twitch [threstwitch], loss of orientation [thresloss] and tetany [threstet], eel length and weight, water temperature (start, end and holding tank). 2. Tab 2 "Experiment 2- Flowing Water". Contains the data recorded during flowing water tests. Sheet includes infomation on day, date eelID, eel length and weight, treatment conditions (flow and field strength), start and end trial time, behaviours(rejection, acceleration, change in orientation [CiO], no change [NC]), flume water temperature (holding tank, begin and end), water conductivity (upstream, downstream, within the electrode array and average). 3. Tab 3 "Experiment 2- Tracking". Contains the variables obtained through tracking analysis. Specifically: distance travelled, time, ground speed and swimming speed both for treatment and control area. 4. Tab 4 "Experiment 2- Velocity + Depth". Contains the water velocity and depth measured during the trials with respect to low and high water velocity treamtents (FlowTreat: L/H) downstream, within the electrode array (velocity only) and upstream. Date of data collection: November - December 2017 Infomation about geographic location of data collection: Chilworth Science Park (Southampton, UK). Date that the file was created: October 2020
