Just a reminder -if needed.

From Wye and Usk Foundation website October 2003

Thirty years ago, there were no goosanders on the Wye. According to the recent Maff (now Defra) survey up to 98% of the salmon parr produced on the Upper Wye are eaten by goosanders. Additionally, Cormorants are seen in groups of up to 55, eating 2 - 3kg of fish each per day. How does the mathematics of this sound: 200 goosander eating, say 10 salmon parr per day. They feed on 300 out of 365 days/year. Result: 600,000 salmon parr gone, not counting the activities of cormorants and other fish eating birds. All this on top of the salmon’s other problems
