Just to poke my nose in....
I have been fishing for over 50 years, brought up by fishing on river mole and Thames for catching Dace, Chub, gudgeon and also bleak bashing!
Very light tackle in those days, learnt how to play fish in, barbless hooks, used to be used for match fishing to improve hooking for dace.
Anyway, move on... times have 'sadly' changed, pot noodle carpers seem to think fishing day ticket waters with as stated before 3.5 test curve rods, 15lb line and hauling some poor double in....
Without dought I think this causes soo much damage.
I now longer fish day ticket waters, however I unforturnatly expect to see the same on my club lake soon.
As for hooks, barbless really dont do more damage, only hook I remember was the Rob Maylin bent hook which was an absolute no no!
