    Not much weight should be placed on the early years - samples were very few compared with later years, but once the surveys get going, the numbers become quite stable.

    Interesting figures in the light of the current views on cormorants. The surveys were taken on rivers.

    Maybe the EA has done a more thorough analysis of their data, but I can't find any.
    The graph in the link, what rivers does it cover? Is it supposed to be an average of all of England and Wales?

    It comes from the gov.uk website, linked to in most of the EA fishing reports.

    There are about 400 records from Scotland, I think border regions - Tweed, Border Esk, etc.

    It covers 181 rivers. Yes, the figure is an average, so some rivers will be much better, others worse.

    Dirt cheap in this case.

    As this appears to be a defense of Cormorants thread, perhaps an alternate opinion is required!

    No they weren't. And it shows a stable trout population, as you say.

    The only logical conclusion:
    People enjoy whingeing more than they used to.

    All these surveys show is there's been a massive increase in stocking over the last 20 years, the truckloads of stockies which our club subs fund are basically feeding the cormorants, without them it would be a totally different picture

    Quite.
    Where I usually fish there is an about 50 yard long section with an EA notice that it is a "fly life survey area".

    They and their predecessor, the NRA, have been doing this for longer than I have been fishing there, which is more than 30 years. But as they have never produced a report because they always say "further investigation is needed" it is merely an existence justification and job creation scheme.

    And fish counts are even more meaningless.

    There speaks the man who's post #5 destroys any argument the old NRA and the present EA might have had about being 'scientific'.

    I don't see anything by JB there, but I have read his remarks on the subject elsewhere (see my blog). They just regurgitate what everyone else says, yet there is little hard evidence to back up the claims.
