Record numbers of young salmon have been counted in one of Yorkshire's major rivers.
More salmon are returning to spawning grounds on the Ouse
The number of parr (juvenile salmon) seen in the River Ure, a tributary of the Ouse, doubled this year on 2004's figure, says the Environment Agency.
In its annual survey, more than 600 were counted at Jervaulx near Ripon.
It attributed the rise to better water quality and the use of fish passes - special channels allowing salmon to negotiate obstacles like weirs.
David Morley, the Environment Agency's officer in charge of fish stocks on the rivers Ure and Nidd, both tributaries of the Ouse, said: "The figures for this year's salmon parr survey were very good.
"They are around what we would expect for a major salmon river, such as the River Eden or River Tyne.
"Back in 1998/9 we were lucky to see any salmon parr at all during our survey, but since then the figures have been steadily rising."
He urged caution, saying the figures applied to only one spot on the Ure.
"However, this is very encouraging news for the future of the Ure and Ouse as self-sustaining salmon rivers, and shows we're doing the right things," he added.
