Environmental DNA (eDNA) is a that can be used to assess and avoid the negative impacts of projects on local biodiversity. eDNA survey techniques allow for the identification of species within their habitats and provide information on all species present in an .

This insight piece discusses the challenges in eDNA sampling and a demonstration of its use to mitigate and monitor impacts during construction and operation of a dam in .

Whether it’s spawning to death, changing s*x, or cloning, fish have developed nearly every strategy to maximize the odds that they successfully reproduce and give their offspring the upper hand to navigate the ever-changing world around them.

Almost three years ago, when we first started our acoustic telemetry project in the Mekong River, the first fish tagged for the project was a record-setting giant freshwater stingray (Urogymnus polylepis) that is now recognized as the largest freshwater fish in the world.

Our team tracked the individual for over 18 months and found that it stayed within a small home range characterized by deep pools – reinforcing the importance of conserving habitats with these features. This research uncovered new insights into fish migration in the Mekong basin – highlighting the importance of understanding migration distances and patterns in culturally and economically important fish species.

Unfortunately, the Mekong and its ecosystem faces growing threats. While a 10-year ban on dam construction along the Mekong River in Cambodia is currently in place, construction continues along other tributary rivers in the 3S basin, including plans for 30 dams along the Sekong River in Laos. The introduction of more dams creates more barriers to migratory fish who have been observed using these corridors throughout our study.

In a region anticipating continued dam development, fish tracking studies like this acoustic telemetry project can reveal critical information helping scientists better understand and protect the Mekong’s incredible freshwater ecosystem and the biodiversity that depends on it.

In a recent publication showcasing the abilities of acoustic telemetry technology, FISHBIO helped reveal new insights into the migratory patterns of the Asian redtail catfish (Hemibagrus wyckioides). Based on local knowledge and limited existing research on the species, this species was previously thought to make only short-distance migrations, or none at all.

In this fish tracking study, FISHBIO and collaborators discovered the Asian redtail catfish making sporadic migrations of various distances within the acoustic receiver network, with one individual traveling as far as 213 km into the Sekong River. This surprising finding challenges previous beliefs about the species’ movement ecology and underscores the need for more fish migration research in the Mekong River.

To learn more about the Asian redtail catfish and other species’ newly observed migration patterns, read this week’s Fish Report: fishbio.com/mekong-fish-migrations!
