In this edition, we highlight recent captures of a giant stingray from the Mekong — since confirmed as the world’s largest freshwater fish — and a rare giant salmon carp from a Mekong tributary. We also look at the monitoring of water quality and fisheries near hydropower projects, plans to develop a green hydrogen plant in the Mekong Delta and the latest global review of inland fish catches.
