One-third of all shark and ray species are ‘threatened with extinction’ due to overfishing, according to a new study.
The findings, which span eight years, show that the number of sharks, rays and chimaera – a group known as chondrichthyan fish – threatened with extinction have doubled to 32.6 percent since 2014.
Eight years ago, 24 percent of species were estimated as threatened.
‘The current observed number of threatened species is more than twice (391 of 1,199) that of the first global assessment in 2014, which reported 181 of 1,041 species were threatened,’ the researchers wrote in the study.
‘If we assume that [data deficient] species are threatened in proportion to the other species, then over one-third (37.5%) of chondrichthyans are threatened, with a lower estimate of 32.6% (assuming [data deficient] species are all [least concern] or [near threatened]) and an upper estimate of 45.5% (assuming all DD species are threatened.’
