Commercial slaughter methods used on Atlantic salmon: determination of the onset of brain failure by electroencephalography
This study investigated the effect of exsanguination without prior stunning, or carbon dioxide narcosis followed by exsanguination, or percussive stunning or spiking the brain, on the time taken to abolish the visual evoked responses (VERS) of farmed Atlantic salmon. Only percussive stunning and spi...
