Plastic bags, human gear are becoming a terrible threat to the life of sharks


Scientists at the University of Exeter, V.Q He recently made a very disturbing finding, that is, hundreds of sharks and rays are caught in the daily plastic.

Based on search results from scientific articles and information from Twitter, the team found about 557 cases of sharks and stingrays caught in plastic in the Atlantic, Pacific and Indian Oceans. .

Meanwhile on Twitter, the group also found 74 cases of sharks, stingrays caught in the net. Including 559 sharks, stingrays of 26 different species from white sharks, tiger sharks to sunfish shark are stuck to the net.

The actual number may be much higher because no large-scale studies have so far listed sharks and rays caught in the net. Most cases are statistically attributed to a broken or disappearing fishing net. Although fishing nets do not pose a threat to other commercial fish, this is a terrible threat and problem for large fish like sharks.

The research team from the University of Exeter said the big threat is spreading throughout the oceans. Grid not only indirectly hinders their ability to move but can also cause pain, even death because they cannot hunt easily as before.

If the grid is unfortunately caught in such parts or the mouth of the shark, they will not be able to move, easily caught in the reef. That is not to mention some types of nets also attached sharp tools, easy to damage their skin and bones.

Not only are fishing nets the culprits that threaten the lives of sharks, but also things like straps, polythene bags or rubber tires can also affect them.

According to research, sharks live in large ocean areas more vulnerable to sharks living near the seabed. Simply because if sharks are usually feeding on the surface of the water surface, they will be more likely to encounter plastic and mesh waste than feeding in deep ocean areas, less affected by plastic waste.

The team claims that sharks are more likely to get caught in the net than stingrays because their body shape is easy to penetrate and catch.

Research co-author and Professor Brendan Godley said that the problem is going too far and out of control while fish species like sharks and rays are still facing daily unpredictable threats.

Finally, the scientists claim, they will need to study more and collect data to get the statistics closest to the current situation.
