Global freshwater fish populations at risk of extinction, study finds
World’s Forgotten Fishes report lists pollution, overfishing and climate change as dangers
Freshwater fish are under threat, with as many as a third of global populations in danger of extinction, according to an assessment.
Populations of migratory freshwater fish have plummeted by 76% since 1970, and large fish – those weighing more than 30kg – have been all but wiped out in most rivers. The global population of megafish down by 94%, and 16 freshwater fish species were declared extinct last year.
