This is actually quite serious. It potentially affects a great deal of things.
Such as consideration for national lottery money allocations - there are plenty of fisheries that could do with enhanced facilities for disabled access for instance that simply won't get considered for them if there are 'only' 280K anglers.
All sorts of other areas of concern potentially come to mind, such as local authority planning decisions (filling in ponds to build houses for example), river clearing, dredging and drainage - why bother troubling with anglers interests if hardly anyone is interested ? - water abstraction - ditto - The issue of the use and navigation in the Broads... the merits of issuing cormorant shooting licences, etc etc etc etc. Sure you can all come up with another half dozen if you think about it.
Plus the risk that some of the bright spark politicians who enjoyed attacking hunting with hounds as a matter of class war - if it weren't for the perception of the sport as toffs in red jackets would it ever have been banned ? I think not... - but who wouldn't dream of attacking a sport with nearly 3 million supporters will think quite differently if they perceive angling as another minority easy target.
One thing I learned as a lawyer when in practice is that if a lie is left unchallenged and repeated and repeated often enough then it will eventually be believed by even those who should know better and acted upon as if it were the truth.
There must be some ability to challenge this erroneous finding, as angling is certainly an interested party in the effect of application of those results. If it were the RSPB faced with a similar duff finding about bird then you can bet there would be national protests and MP's asking questions in parliament in pretty short order. But Angling.... with no effective unified and single equivalent representative charity we're stuffed.
(And this is not meant as a dig at the likes of the ACA etc, but they and all of our other bodies have a nasty tendency to be staffed by well meaning good old fashioned british amateurs and / or fragmented into small sectarian interests..... with no real media savvy or conception of how to go about generating real pr).
[Edit]though having gone on to read the NUBA Q&A's they at least see the dangers. But what publicity or pr has followed ? None. I only know about this from reading this post in a single posting on a personal interest website, ie. here.... Not splashed all over MSN news or the inside sporting pages of any newspaper. PR is the name of the game in this modern world if we want to hang on to our sport, let alone enhance its facilities and position. And our PR as anglers is woeful....[/Edit]
