The other day when I was down by the River Ericht I noticed several dead fish and was also fortunate enough to get close up to some salmon in the pools below Cargills Leap. Some of the fish were covered in some white looking matter and I didn't have a clue what it was. Fortunately I had guests staying who were in the area doing a bit of salmon fishing so I showed them the photos and they even went for an evening stroll up the river to have a look. This morning I had a letter from them and they had printed off what was wrong with the fish, very interesting and kind of them to inform me, you learn something new every day.
