It is quite simply an iconic and extremely important part of our countries heritage and economy, helping Scotland's image the world over. It's not some form of 'class plaything' but available to all, the sooner someone within the Scottish Govt realise this (and help give it the protection it deserves) the better.
On a slightly different level, simple arithmatic; the more native / natural fish spawning in the system, the better chance of survival / increased future stocks. Stop killing 'em at sea, stop killing their food source, stop polluting their habitat, who knows maybe other marine species might benifit as well (apart from sea-lice that is).
Last thing, not directly related, C&R is, in my mind, the way to go, but; as long as we remember numbers caught will include multi-landed fish and therefore the true reflection of what that water produced is slightly slanted.
Right enough said by me, i'm away back to the troots
