Similar scenario here mate its a catch and release river which i don't mind at all I'm not too fussy about it either.
Thankfully most of the poaching i see isn't going to affect the numbers of salmon most of it is fishing without a permit which is harmless fun especially for youngsters.
I think salmon farming and fish eating birds like cormorant and goosanders are much bigger threats to migratory fish and resident fish.

I counted 49 various fish between the two birds, salmon parr brown trout and sea trout smolts.
I'll not start on salmon farming in regards to the disgraceful fish welfare and the environmental disaster that it is.
Loch Maree was world famous for its sea trout fishing, damn disgrace.
