From the large-toothed Lake Turkana robber in Kenya to the Mekong giant catfish in south-east Asia, many of the world’s freshwater fish are at risk of disappearing, the first International Union for Conservation of Nature (IUCN) red list assessment of the category has found.
Nearly a fifth of all threatened freshwater species are affected by climate change, from impacts such as falling water levels, shifting seasons and seawater moving up rivers.
To ensure the results of conservation action are durable, we need to decisively tackle the interlinked climate and biodiversity crises,” said the IUCN president, Razan Al Mubarak.
Big leaf mahogany, among the most commercially sought-after plants on the planet, is now classified as endangered after its numbers fell by 60% over the past 180 years due to unsustainable harvesting.
The Atlantic salmon, previously common and classified as a species of least concern, is now near threatened on the IUCN red list after its global population fell by 23%, having vanished from many rivers in the UK.
The fish, which lives in both fresh and saltwater, has been affected by widespread habitat loss, global heating and dams that block access to breeding sites.
