Find is ‘hopeful sign’ the species, one of world’s largest and rarest freshwater fish, is not at imminent risk of extinction
Six critically endangered Mekong giant catfish — one of the largest and rarest freshwater fish in the world — have been caught and released in Cambodia, reviving hopes for the survival of the species.
The underwater giants can grow up to 3 metres long and weigh up to 300kg. They are found only in south-east Asia’s Mekong River but in the past inhabited the entire 3,044-mile (4,900km)-long river all the way from its outlet in Vietnam to its northern reaches in China’s Yunnan province.
