Police say the pair, aged, 30, and 45, were stopped at Broxy Cottage near the A9, south of Luncarty, last month.
Both men had allegedly been fishing illegally in the Tay during the close season.
Anglers are only allowed to fish for salmon in the River Tay – Scotland’s longest and largest salmon river – between January 15 and October 15.
The fishing season for trout typically runs from mid-March until September.
In addition, rod fishing for salmon in the Tay is not permitted on Sundays.
Restricting fishing to a season aims to help protect fish stocks and give them the best chance to reproduce.
