A massive rescue operation is under way in Inverness to help thousands of young salmon trapped in the Caledonian Canal system, closed during lockdown. The fish, known as smolts at this stage in their lives, are heading in shoals towards the sea – but now find themselves trapped between Dochgarroch and Muirtown Basin.

The clarity of the canal water during lock-down has helped highlight the extent of the problem. Ness District Salmon Fishery Board and Scottish Canals are working together to help release the smolts, and encourage them downstream into the sea.
