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.
