The electrical stimulus was pulsed DC, ranging in frequency from 4 to 40 Hz. Involuntary muscular contractions were induced by this stimulus which caused the majority of fish to flee from the electrified zone. Reactions were classified into a few broad categories and the approximate fish size in each observed event was recorded. The results suggested that the most efficient frequency for inducing flatfish to leave the bottom is around 20 Hz, and that large fish are more strongly stimulated by an electric field than small fish; the latter being a significant demonstration under natural conditions of a theory based on aquarium experiments. Observations were made on the reactions of flatfish to a towed chain to assess its comparative efficiency in forcing fish to leave the sea bed.Read More
