Well, you might still be familiar with catching fishes like rays and sharks with the help of old school method “shooting the scuba tank”. As of now, it appears that researchers have discovered a new trick to trap those predators using magnetic and electric fields of magnets.
Scientists at Australia’s University of Newcastle have discovered that joining magnets to business angle traps can effectively avert sharks and rays which mean fewer sharks are gotten as bycatch.
The examination, distributed in Fisheries Research, found that ordinary magnets could decrease bycatch rates by 30 percent, and prompt a comparing increment in angle being gotten by business angle traps.
As indicated by the investigation, sharks and rays have exceptional detecting pores around their nose that assistance them find prey and which are especially delicate to magnetic and electric fields. By kitting out a fish trap with $2 magnets – at an aggregate cost of generally AU$30 (around $20) per trap – the scientists say fisheries can utilize the sharks’ own particular science to help spare them.

The World Wildlife Fund assesses more than 300,000 little whales, dolphins and porpoises bite the dust each year subsequent to getting tangled in angling nets; however University of Newcastle lead scientist Dr. Vincent Raoult says magnets could be a straightforward method to decrease the issue.
“While many of the elasmobranchs [the subclass of fish that includes sharks and rays] unintentionally caught are released back into the ocean, the stress from being out of the water and handled are likely to have repercussions that will last for a period of time after they are released,” he said.
“Using magnets not only reduces incidences of elasmobranch bycatch, but also increases profitability for fishermen as they spend less time accidentally catching sharks and rays, and more time catching the fish they want”, he added further.
Concludingly, it appears that the magnet is the biggest and wisest predator of them all…
