Electrified bar racks for fish protection at water intakes - risk of fish injuries due to electric fields

Full description

01_Flume and Racks – Blueprints and photos of the Flume and the used intake rack configurations. 02_Waveforms measured – Plots of all waveforms, measured on electrodes with opposite polarity. 03_Documentation experiments – Excel document containing the following: ·         Information on individual fish (species, total length, width, weight, date of arrival) ·         Summary and plots of fish size distribution ·         Information on experimental group and observed injuries per fish (dark discolourations, spinal injuries, haemorrhages, descriptions of chronical and acute anomalies) ·         Summary and plots of observed injury incidence per experimental group 04_Videos of fish interactions – Compiled videos consisting of all individual rack interactions observed for the tested configurations. 05_Photos of dark discolourations – Photos of all fish with observed dark skin discolourations taken directly after an experiment. For configuration DS1/Passage no dark discolourations were observed. 06_Photos of haemorrhages – Photos of filets of all fish with observed haemorrhages. For the configurations R3/Non-Passage and DS1/Passage no haemorrhages were observed. 06_Photos of haemorrhages – Photos of filets of all fish with observed haemorrhages. For the configurations R3/Non-Passage and DS1/Passage no haemorrhages were observed. 07_Boxplot_TL - Size distribution of fish over experimental groups.
