We’re still involved in work over on the River Mekong in Laos. One of our engineers Jay recently travelled out to the site of the Don Sahong hydropower scheme, in part to install some cameras for monitoring fish migrating at the falls. While there, he saw a lot of the small fish species called ‘Pa Soi’ (Henicorhynchus sp.) and took the impressive video below of lots of Pa Soi migrating in a small channel.
