Rescue of thousands of trapped salmon

Thousands of young salmon have been found trapped in a stretch of the Caledonian Canal.

The smolts were spotted because the water is so clear with no boat traffic due to lockdown restrictions.

The fish have been unable to find their way out of the canal and into the nearby River Ness, and then downstream to the sea, using what are called smolt passes, which were built in 1869.

Ness District Salmon Fishery Board is leading a rescue effort. It has asked Scottish Canals to "flush" the canal system between Dochgarroch and Muirtown in Inverness twice daily by opening large sluice gates on the lock gates. This allows the fish to swim downstream.
