Catsharks were exposed to electrical field used to catch brown shrimp or flatfish. Prey detection of sharks was tested using a prey simulating bio-electrical field. Sharks were still able to detect a prey bio-electrical field following exposure. No impact on bite response to prey simulator No difference in timing of bite response to prey simulator
