Deploying the First Ever Acoustic Telemetry Network in Cambodia

Case study :

Acoustic Telemetry

Partners:
FISHBIO, USAID Wonders of the Mekong project and FiA
Year:
2021
Location:
Ramsar, Stung Treng

The lack of involvement of the local community and fisheries with tracking projects often tagged fish are caught, and receivers get lost during the monsoon floods as there is no one to look after them.

Tracking fish movements in a large transnational watershed can be very difficult which results in poor information about the impact of conservation measures.

With an annual fish harvest of 1.8 million tons, the Mekong is one of the largest providers of proteins to the region and is also home to a wide range of biodiversity which includes the Irrawaddy Dolphin, giant freshwater stingray and the Mekong giant catfish. However, fish migration data is still lacking as most of the data are from social surveys rather than actual scientific data. With expanding population and ongoing development in the region especially the two dams planned for the Cambodia Mekong it has become critical to assessing fish movements and migration patterns.

Nearly 300 fish representing another 26 species were tagged and released in Cambodia and Lao PDR

Acoustic Telemetry X Community Collaboration

Young Eco collaborated with FishBio, USAID Wonders Of Mekong and FiA to launch first ever Acoustic Telemetry Network in Cambodia to determine migration patterns and movement dynamics at the confluence of the  3S Basin and across the Lao PDR border up to Khone Falls in north eastern Cambodia. Acoustic Telemetry allows individual fish to be tracked using unique signals upto 1000 meters away. 


The collaborative approach ensure everyone involved was aware resulting in tagged fish staying safe and less loss of signal receivers.
