Electrofishing eel, salmon and trout: impact of waveform and frequency on capture-per-unit-effort and spinal damage
Performing fish survey protocols with different electrofishing equipment and settings can lead to difficulties in comparing the data obtained. In this study, we captured two fish taxa (i.e. the European eel and salmonids: Atlantic salmon and brown trout) in the field using four models of electrofish...
