CNA – January 28, 2021<\/p>\n
TOKYO: Overfishing has savaged populations of some sharks and rays by more than 70 per cent in the last half-century, leaving a “gaping, growing hole” in ocean life, according to a new study.<\/p>\n
Decades of data show an alarming decline in species ranging from hammerhead sharks to manta rays.<\/p>\n
Among the worst-affected is the oceanic whitetip, a powerful shark often described as particularly dangerous to man that now hovers on the edge of extinction because of human activity.<\/p>\n
Targeted for their fins, oceanic whitetips are also the victims of indiscriminate fishing techniques. Their global population has dropped 98 per cent in the last 60 years.<\/p>\n
“That’s a worse decline than most large terrestrial mammal populations, and getting up there or as bad as the blue whale decline,” Nick Dulvy, a professor at Simon Fraser University’s department of biological sciences, told AFP.<\/p>\n
Dulvy and a team of scientists spent years collecting and analysing information from scientific studies and fisheries data to build up a picture of the global state of 31 species of sharks and rays.<\/p>\n
They found three-quarters of the species examined are now so depleted that they are threatened with extinction.<\/p>\n
