I am sorry guys, I have had to remove my posts. Appologies.
That's OK Rob .... estruary fishing and even fishing from a beach has always been a right "can of worms"!
This is a great pity, as attempting to fish for a species can often be seen as "suspicious" by riparian owners because you might end up catching migratory fish
I say a pity .... because this has also historically been a bit of a problem for genuine brown trout anglers on some rivers.
To be totally honest though the problem that I see, is that you can't really blame the owners or river management
Because ( as with most aspects in life ) there are good folk and "not so good folk" ..... and these have spoilt it for the rest of us
Best wishes
Mike
