    Boris has a few vacancies I believe.

    What controls are there that I could be in favour of?
    Well that's sort of my point not yours. You're worried about it, what are you going to do about it?

    My only point is that pink salmon is probably not a good thing, we have seen enough invasive species to know that their first appearance is not the point of stability on which we can judge.

    I suspect dinosaurs shared you concern when that tiny mouse-like creature showed up.

    There are probably half a dozen reasons for decline of atlantic salmon, river habitat,salmon farming, contraceptive pill,bad agricultural and fishing practices etc; but I agree with you ocean warming is probably the most significant in moving the salmon's primary food source further north.
    With regard to pinks the rivers in the far NE have been electro surveyed for the last several years, I met one of the team on Friday who said they hope to be out this week. I do not think they have found any evidence of pink parr.

    That might in part be down to the timing of the electrofishing. Most of it is done in July/August & September (well it is on the Naver, Halladale & Helmsdale and I expect nearly everywhere else for the National Electrofishing Program) when the only pinks likely to be present are adults or eggs in redds.
    But yes as far as I know no pink fry or parr have ever been electrofished in this corner of Scotland.
    Also to the best of my knowledge from the Helmsdale round to West Sutherland there have only been two adult pinks confirmed this season, one form the Helmdale and one from the Polla plus one possible sighting from the Naver. It is possible that a few may have spawned but not been notice due to high water over much of the summer but there clearly aren't more than a handful this year.
