Majestic, beautiful, civilized creatures of the water that roam the deep oceans of our planet Earth. These creatures are also known as sharks. Sharks and humans had mostly kept 'peace' throughout the centuries but have had many problems affecting the lives of humans. Admittedly, humans do look like floating pieces of free food from their perspective. Although sharks can cause for humans, individuals continue to find effective solutions to those problems. One of the many problems sharks have caused for humans is appearing in the daily catches of fisherman. A specific type of species known as the spiny dogfish have caused a problem for fishermen stretching from Maine to South Carolina. According to the president of the Midcoast …show more content…
When those fish end up in the same net as the dogfish, the fishes' skin rubs against the sandpaper-like skin of the dogfish and makes the fish look less appealing to customers looking to purchase the fish. Since dogfish do not have bladders, they cannot be sold as the taste of urine does not appeal to human taste buds. The best solution to keep sharks away from the fish fishermen catch to make profits is to use chemicals and magnets. The chemicals Eric Stroud found "have a long range and works on most species of sharks" (Stopping Sharks by Blasting Their Senses), meaning they can use these chemicals to help sharks from being killed and save the fish caught by fishermen. The magnets used overload the sharks' ability to sense their prey. Magnets developed by SharkDefense are made of iron, boron, and neodymium are unlikely to inflict pain …show more content…
Data gathered by the Florida Museum of Natural History claimed that "In 2013 there was 72 unprovoked shark attacks on humans, 10 of which were deadly" (An Electric Fence Wards Off Sharks). Surfers alone are 50% of those attacks and areas with larger shark populations such as Australia, Hawaii, And South Africa have a greater chance of receiving shark attacks. Due to all the unprovoked shark attacks on humans, the KwaZula-Natal Sharks Board in South Africa has begun a plan to keep sharks away from the beaches. Researchers have stretched about 330 feet of electric cable along the sea floor to see what effects it has to the local Great White sharks. This works by emitting a low-frequency electric field in the waters that make the sharks turn back since the Ampullae of Lorenzini (a pouch of gel located in the shark's nose) is especially sensitive to the electric frequency emitted by the "fence". Project leader, Paul Von Blerk, describes the behavior as "similar to a human's reaction to extreme heat" (An Electric Fence Wards Off Sharks) because once the discomfort of the flame becomes too much, we move away from the heat; the sharks move away since the electric field is too much for their electromagnetic-sensing organs in their nose. The fence is used in addition to the Shark POD, a surfer-safety device sold by the Australian company Shark Shield. The Shark POD, which can be mounted to a surf board or
