Anglers are competing for what is believed to be the most valuable game-angling trophy in Britain.
The solid-silver accolade was unveiled at the opening of the River Deveron fishing season by Shetland fiddler and angler Aly Bain.
It will go to the angler who catches the biggest salmon and returns it to the river to spawn.
The trophy commemorates the 1924 catch made by Clementina Morison, who landed Britain's biggest fly-caught salmon.
At 61lbs, it remains the heaviest recorded salmon taken on a fly in the UK.
Ms Morrison's descendants and the Deveron Trust commissioned the trophy to mark the success of conservation work on the river.
