Radical conservation measures
The advice has come from the Tay District Salmon Fisheries Board on the opening day of the 2010 angling season.
The board has said that no salmon should be killed before June and afterwards anglers must limit themselves to one male salmon a day.
The policy brings the restrictions on the Tay closer to those already in place on the River Dee. On that river 98 per cent of salmon are returned to the water to allow them to continue upstream to spawn, BBC News reports.
The start of the salmon fishing season on the River Tay is always a cause for celebration amongst anglers. But this year's event has been overshadowed by real concerns about dwindling fish stocks, the news source wrote.
The Tay District Salmon Fisheries Board believes radical conservation measures are required to let more salmon to return to the river.
