The Mekong River is the 12th longest river in the world and the third most biodiverse river in terms of fish next to the Amazon and the Congo. It boasts the world’s largest inland fishery, providing food and livelihood for millions of people. It is a transboundary river that runs through six countries: China, Myanmar, Laos, Thailand, Cambodia and Vietnam, and supports hundreds of extraordinary species –- from birds to mammals, reptiles, and fish. It is also important habitat and the last remaining stronghold for species at the brink of extinction, including the giant freshwater stingray, giant ibis, Siamese crocodile, and the Mekong giant catfish.

The workshop was part of the USAID-funded Wonders of the Mekong project, a joint initiative that seeks to understand and share the value of the Mekong River ecosystem....

It was an unlikely relationship. I grew up in central Arizona, one of the driest places in the United States. My parents are economists. My two brothers went into finance. Catfish aren’t the cutest or most loveable creatures. Even so, by the time I made it halfway around the world to see my first one,...
