Atlantic salmon (Salmo salar)

The River Ewe at Poolewe

The River Ewe at Poolewe

Between June and September each year, many hundreds of adult salmon return from the North Atlantic underneath the road bridge at Poolewe and swim up the River Ewe into Loch Maree.

Many of the salmon are 'grilse' which have been at sea for little more than one year. Larger salmon may have spent two or more winters at sea. In late autumn, salmon run upstream to lay their eggs in river gravels. Many salmon die after spawning and their carcasses are eaten by otters, foxes or other animals. Young salmon hatch in the spring, and are know as 'fry' in their first summer, as 'parr' in their 2nd and 3rd years before turning silver when they are known as 'smolts' and migrating downstream into the sea and on towards arctic feeding grounds.

WRFT has found juvenile Atlantic salmon in 30 river systems within the WRFT area. Salmon are the most important species for fisheries. The Little Gruinard River has been designated under the EU Habitats and Species directive as a Special Area of Conservation (SAC) for Atlantic salmon.

  • Little Gruinard juvenile fish assessment 2006 report
    This illustrated report presents the results of the 2006 WRFT Little Gruinard electro-fishing survey. Relationships between juvenile salmon abundance and habitat characteristics are discussed. The natural production of juvenile salmon in this Special Area of Conservation (SAC) for Atlantic salmon could be strengthened through restoring levels of natural fertility within the Little Gruinard catchment area.  Posted: 22/09/2008 (964KB)
