These datasets (e.g., 'Starved Rock fish clearing_multi-beam imaging sonar fish data_Pre-clearing_Sonar-s1.csv') include exported information (e.g., fish detection counts) from processed fixed-location multi-beam imaging sonar and mobile side-scan sonar data. Fish abundance in the navigation lock was determined using mobile side-scan surveys, while multi-beam imaging sonars were used to determine fish counts relative to time (i.e., fish per minute). The datasets were used to examine the efficacy of electricity and underwater acoustics, used in tandem, to affect fish abundance (as determined by hydroacoustic data sampling).
