Electrified horizontal bar rack bypass systems - electric field and effects on species-specific fish behaviour

Videos_Rack_Interactions - Compiled videos consisting of all individual rack interactions observed for the tested configurations C1-C6 and exploratory setups E1-E4 (Table 2.1). For certain setups one video containing all rack interactions (_all) and one video containing only rack passages (_passages) is included. For scale reference: the white crosses on the flume bottom are spaced 50 cm apart in flow direction. In the direction transversal to the flow, they are placed at y = 0.1, 0.375, 0.750 abd 1.125. The Bypass is 25 cm wide. Versuchsresultate_Flume2020_HBR.xlsx- Excel document containing the observed behaviours for the CBR experiments with European eel ID - Experiment ID. For each experiment, three fish were tested in the flume corresponding to ID-1, ID-2, ID-3 Date_Catch - Date of Electrofishing Date - Date of experiment Start_Exp - Start of experiment Conf - Configuration according to tab - Configurations U0 - Average approach flow velocity U_by - Average flow velocity in the bypass Fish_ID Verwendung - Value between 1 and 3, indicating if the fish is exposed to the flume for the first, second or third time TL - Total length Height - Height of the fish Eye - Eye diameter Time_L1 - time at which a fish entered the area observable from the side window Time_Behaviour - Time the behaviour was exhibited By without contact, By with contact, Refusal controlled, Refusal aprupt, Rack passage - Value 1 if this behaviour was exhibited, 0 otherwise. Rheotaxis contact - Rheotaxis when approaching the rack and exhibiting the behaviour - P= positive, N = negative Location contact - B = close to the flume bottom, M = middle of the water column T_Tanks, T_canal, Cond Kanal - Temperature in °C of the holding tanks and the flume and specific conductivity at the time of the experiment.
