Confidence: I'm as sure as I can be.
Notes: My brother was keeping an eye on 13 salmon just as spawning time approached. They were moving about a bit from day to day, in a stretch of river. Then on 21 Dec 05 he found these 2 dead, on the bed of the river, one missing its face. Of course, sods law, the 2 dead fish were both females with the loss of approx 9000 eggs. We still dont know why they died, harrasment by otters or people at night? Disease?
