One
experiment investigated whether a personal deterrent apparatus could keep
a great white shark away from static bait.
142
The scientists used chum
143
to
attract sharks to the test area, concluding that such heightened predatory
conditions would simulate a worst-case scenario for the divers.
144
The
results of that study revealed that personal shark deterrent devices can
reduce the already low chances of a shark bite by almost eighty percent.
145
Once electrical shark deterrent devices were proven to be effective on a
small scale, inventors and researchers turned their attention to larger
devices such as those that can be attached to boats
146
and, relevant to this
article, cables that create an exclusion area to protect beaches.
147
Aside from the discomfort experienced by sharks,
148
which is similar
to the changes in human sensitivity as one gets closer to a heat source,
149
there are no major negative impacts to other organisms. Marine mammals
and bony fishes do not have the same electrosensory organs and thus will

143. Chum is a mixture of blood, bones, and other fish and animal parts deployed in the
water to attract sharks to a specific area. It is often used for shark fishing, shark diving, and
other tourism needs. See, e.g., Mary Bates, Is Chumming Leading to More Shark Attacks,

however, it is important to note that this particular method would have a similar impact on
other elasmobranchs (skates and rays). See, e.g., Jennifer Langston, Proton-conducting
