    (1)If it is in river water quality why in 2010/11 did we see a wide spread increase in salmon numbers,did the water quality suddenly improve for these years and then revert back to poorer quality.
    (2)If it is due to in river predation was there less predators in these years for some reason.
    (3)Was there more smolts produced and was the size and quality of these smolts any different from other years.
    (4)Was the tv programs for these years **** so more people went fishing instead so the cpue was greater.
    (5)Was there more food available for the smolts and the growing salmon while they were at sea in these years.
    (6)Was the quality of the fishermen greater for these years.
    We are not just speaking about 1 or 2 years on 1 or 2 rivers in 1 country but these peaks happen on many rivers and in many countries simultaneously, so can we say it is all down to in river problems all happening at the same time or can we put it down to the amount of food available for the fish at sea.
    Salmon numbers fluctuate wildly from year to year and always have. Whenever we get big lots of fish itís most likely a combination of factors, cold winters preventing early hatching, wet springs ensuring more smolts get to sea and good abundance of food at sea would all have a big effect. A wet summer with good angling conditions can boost catches too. Of course the opposite applies as well. The danger is looking at one or 2 years in isolation doesnít give any insights in to whatís going on. 5 and 10 year averages give a better trend indication. Some rivers are improving some are much the same and some are getting worse.

    I think there are a variety of things that effect abundance including global, regional, national and local issues. To try to look at salmon abundance through an opinion of all at sea or all in river is so simplistic I donít actually believe anyone does. The recurring, and unanswered question is what exactly can be done about changes in marine mortality? Pretty much nothing! Whereas a great deal can be done in river, in estuary and in near coastal zones. Harping on about increased marine mortality achieves absolutely nothing of any use. It offers an excuse for inaction and increasing restrictions both of which cause real harm. By far the most effective and sensible approach is to forget about what we cannot change and concentrate all our efforts on what we can.

    Totally agree mate - but a turd is a turd however you dress it up.
