Vital Mekong fish corridors tracked for first time, but funding cuts threaten future research

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 we…
