The first-ever acoustic telemetry network in the Mekong River has tracked key migration corridors critical to the survival of fish in Cambodia and Laos. To conduct the study, researchers caught fish from a dozen species and implanted them with small electric transmitters before releasing them back into the river. A network of receivers allowed the researchers to follow the migration movements of 81 of these tagged fish during both the dry and wet seasons.

By implanting fish with small electronic transmitters, researchers were able to track key migration corridors in the Mekong River. The findings underscore the threat that dozens of planned dams along the Mekong will cut off these vital migratory paths. The study, which the lead author describes as a “pilot effort,” was funded by USAID; the funding gap caused by the U.S. foreign aid freeze leaves the future of such research in question.

This month, conservationists released 10 captive-bred Siamese crocodiles into Cambodia’s Virachey National Park as part of a regionwide effort to boost wild populations of the critically endangered crocodilian. The release marked the first such attempt in Virachey. Since the species was rediscovered in Cambodia in 2000, nearly 200 crocodiles have been released in Cambodia’s Cardamom mountains region.
