Sorry to say but make that three.
The West coast of Scotland has be polluted by these fish farms for years.
Decline and or extinction of salmon and sea trout runs in rivers.
The sea polluted with tons of **** from the fish.
Algae blooms that have poisoned shellfish.
Millions of tons of sandeels from the food chain removed to feed these fake salmon, starving the marine environment.
Need I say more!!!

Sorry to hijack your post d j vass, we have not turned the corner. Please do what you can to expose this menace and then perhaps we can all enjoy sea trout fishing at its best in the near future.
ATB,
Graham
