The number of sharks that live in the reef at TBD decreases

According to statistics from an international group of researchers published on April 27 in the US, the number of sharks living in the Pacific reef has plummeted, especially near areas of high population density. .

Statistics show that a large number of these sharks have disappeared in the past three decades with 30-70 million people killed by humans each year in the world. The cause of this phenomenon is due to excessive shark hunting to satisfy the demand in Asia for shark fins, random fishing activities of industrial fishing grounds and recreational fishing activities. . This massacre particularly affects ocean shark species.

Marc Nadon, a researcher at the Joint Research Institute for Marine and Atmospheric Research (JIMAR), the lead author of the study, said that around the densely populated areas of the Pacific, the number of sharks live. on the reef is extremely small compared to the seas around the other islands in the same area.

Mr Nadon said: 'We estimate that the number of sharks living on the reef has plummeted around densely populated islands and this decline has exceeded 90% compared to those of sharks living in those Coral reefs and isolated islands " .

Currently, the shark species is less than 10% in densely populated areas.
