Analysis of permanent magnets as elasmobranch bycatch reduction devices in hook-and-line and longline trials [PDF]
, 2011 Previous studies indicate that elasmobranch fishes (sharks, skates and rays) detect the Earth’s geomagnetic field by indirect magnetoreception through electromagnetic induction, using their ampullae of Lorenzini. Applying this concept, we evaluated the
