      Lumpfish, ranging in size from 146-4200 g, were placed in an electric dry stunning unit head first and exposed to 50 Hz, 240 V AC for 0.5 or 1 s and thereafter 4.5 or 9 s of electricity, thus 5 and 10 s respectively. In seawater, lumpfish were exposed to an electric field equivalent of 4.6 Vrms/cm, 100 pps square AC, with 15% duty cycle for 1 s and thereafter 9 s. This to verify whether the animal ...
