A broken garden fence and a duck?

My back garden door and fence took a battering from the winds just before Christmas (I haven't had time)! Anyway, I remembered a Gate & Fencing Company on a local industrial estate - I took a stroll down to where the company was - but it looks like they have gone out of business!

My little "trip" wasn't a complete waste of time. I took a little detour and "blipped".

I "blipped" the ducks on a little landscaped canal which runs through the area.

In this politically correct world: Does the NO Fishing notice apply to the ducks OR is it: One rule for us and another for ducks?
