The death of Medici was the first shark death in Massachusetts since 1936. “We are on the right track, right?” Doyle said. “Take three bites in 14 months.” After her friend’s paddle panic, Doyle co-founded Cape Cod Marine Community, A non-profit organization dedicated to improving public safety.The team has helped connect Pilot with lifeguard Remind them of possible sharks.It raised funds for drones and giant car-sized balloons with high-definition cameras that can spot sharks, and advocates such as Smart buoy, A marine monitoring and warning system that can detect large marine organisms in the water.
But six months Learn Commissioned by Cape Town and released in October 2019, it studied the efficacy of more than 20 shark mitigation strategies, including smart buoys, nets, virtual barriers, electromagnetic devices to stop sharks, and drones. The report ultimately concluded that most either do not have enough evidence to prove that they are indeed effective, have limited efficacy, or do not work on the coastline of Cape Cod-except for one: changing human behavior.
Suzanne Grout Thomas, director of community services in Wellfleet, a fishing town about 15 miles from the tip of Cape Cod, said this has been the main way public safety officials have reduced the risk of sharks in the past 8 to 9 years. Since the death of Medici, the town has strengthened their agreement, limiting the distance people can swim, and closing the beach, sometimes several times a day. Lifeguards and even some members of the public have accepted “Hemostasis“The practice of biting, and the sign warns of the presence of sharks. “Our greatest contribution to this is to educate the public about the way sharks behave,” Thomas said. She has seen signs that it is working. People swim away from the shore Nearer, or not swimming at all, lifeguards will react faster when they whistle to clear the water.
Last summer, Wellfleet had two buoys to send signals to lifeguards. If marked sharks appear within 200 yards, they can summon swimmers out of the water. “Hundreds of sharks slapped on these buoys last summer,” Thomas said. Her goal is to have one on every beach.
But she admits that this method has its limitations. Not every great white shark is labeled, and mobile phone network services in Wai Cape Beach are still uneven at best, which means that any real-time notification system is difficult to share widely.
When researchers and residents considered the best mitigation strategy, one strategy—culling—was shelved.This is a method Some countries Tried. For example, Western Australia implemented a regional policy in 2012 to track, catch and eliminate sharks that pose an “imminent threat” to beach visitors.according to International Shark Attack Archives, According to a global database, shark attacks in Western Australia are on a downward trend, but have soared again in the past few years.Although it is difficult to estimate the impact, many experts say that eliminating items Not working.
Now, technological advances and increasing understanding of animal intelligence have led researchers to hope that another management option might emerge, namely, management options that try to understand rather than change shark behavior.
seabed Cape Town is a huge patchwork of sandbanks, shallows and deep trenches. The shark has learned how to navigate this underwater labyrinth. They are now hunting in what some people call the “low valley”, which is a deep water area where a letter C is formed between the outer sandbar and the beach. Because seals often appear in these shallow waters near the coast, sharks have learned how to attack laterally instead of ambushing from below. In fact, according to a recent report, unlike other parts of the world, Cape Cod sharks spend half of their time in shallow water below 15 feet.
