KARACHI:
A decline of more than 85 per cent has been reported in Pakistan's shark resources over the past 50 years, according to an analysis, titled 'Half a Century of Global Decline in Oceanic Sharks and Rays', published in a scientific journal, Nature.
The study concludes that the shark population across the world has reduced by 71 per cent since 1970, with shark and ray populations continuing to undergo a staggering decline globally.
Top 20 shark scientists, who contributed to the article, have attributed the decline, primarily, to overfishing.
The scientists have extrapolated that of 31 species of sharks and rays examined during the analysis, 21 are currently facing the risk of extinction, as around 100 million sharks are caught each year.
