The study said that the magnet can successfully resist sharks to avoid sharks being caught

The study, published in the Fisheries Research, found that ordinary magnets can reduce the rate of false catches by 30% and lead to a corresponding increase in fish caught by commercial fishing gear.

According to the study, sharks have special sensing holes around their noses that help them locate prey and are particularly sensitive to magnetic and electric fields. The researchers said that by using a $2 magnet to create a fish trap - the total cost of each trap is about $30 (about $20) - the researchers say fishermen can use the shark's own biology to help save them.

The World Wildlife Fund estimates that more than 300,000 small whales, dolphins and porpoises die each year after being caught by fishing nets, but Dr. Vincent Raoult, Principal Investigator at Newcastle University, said magnets may be an easy way to reduce problems.

“Although many unconsciously captured cartilage fish (including sharks and squids, etc.) are released back into the ocean, the pressure and post-treatment pressures brought out of the water after they are released may last for a while. Not only can it reduce the incidence of cartilage fish being caught, but it can also increase the profitability of fishermen because they spend less time accidentally capturing sharks and so on, so they have more time to capture the fish they want."
