Have been asking for many years why we have so many salmon "conservations" bodies. One body covering the lot has a lot more clout. AS said before it reads to me like empire building. The money saved on offices and others could be far better spent on looking after the fish and the anglers who are the ones who spend the cash.As you say it is very difficult to keep responders on topic.
It seems to me that all angling, fishing charities need to speak with a single voice because the first thing any politician wants to know is how many people do you speak for. The more people you represent the more they react to your needs as most politicians and political parties live with the constant fear or becoming deselected / voted out or irrelevant. It is a very unforgiving business in which numbers count.
Having said all that I think you also need to look outside the UK at some of the international organisations who are dealing with an even bigger problem which is the wholesale plundering of the worlds oceans by overfishing and pollution. Viewing the Netflix film on this subject is a must for all of us who are interested in saving our rivers and waterways but the only way we can make a difference is by all interested charities and organisations forgetting any differences in their aims and purpose and to garner support on an international scale just like Greenpeace and others do. Size really does matter when it comes to changing hearts and minds. Frankly we should start by forgetting we are Interested in English or Scottish or Welsh rivers and act as one UK force. That UK force then represents us at an international level and it might well include the small coastal fisherman and others who stand to lose everything if we don't act now. Sewerage dumping, pollution, plastics (including commercial fisherman's equipment) bottom trawling, bye catch, sand eel fishing for fertiliser, farming runoff, forestry runoff and a hundred more issues which need addressing but most importantly we need the public to start to recognise that we are trespassing upon the very environment which fish and other waterborne creatures live and survive in. We have got the world thinking about global warming and air pollution so surely the next step is to persuade the public that all their efforts to rid the world of polluting greenhouse gasses is a worthless exercise if we do not also make a serious and concerted effort to clean up our oceans and waterways and our fishing practices at the same time . This requires all interested bodies to create a single forum which speaks with one voice. Sounds Grand doesn't it but making it happen is going to be the problem as everyone, however, well meaning has their own agenda. My only suggestion is that we start with our various angling trusts and charities etc maybe also our small coastal fishermen creating a dedicated forum, inviting others to join / participate, getting political sponsorship and then seeking out others internationally with a similar agenda. Can we find one dedicated person of international standing to step forward and lead us lesser mortals into battle. Suggestions on a postcard please.
