When I initially started this thread it was about what hooks to use when snag fishing,it has moved on quite a lot now to the ethics of snag fishing which is not what I wanted but it has the blessing of a super moderator(whatever that is)

so here are my thoughts.
I don't subscribe to the ''sporting chance'' theory,I want to land every barbel I hook and as quickly as possible(as we all do).That is not to say that the fish does not have a chance,even using the tackle I have described it is by no means a foregone conclusion that it will be banked and is still a stiff challenge.
Judging by the amount of terminal tackle I have removed from the mouths of several barbel this year there are a significant amount of anglers fishing for them with inappropriate tackle near snags.
As someone has mentioned how far away from snags do you fish I would like to make it clear that I wouldn't drop my lead right amongst some sunken tree roots,sharp rocks or other obstructions,that would be foolhardy and even with conger gear would result in lost fish.
I try and ascertain where the snag is by casting a lead around and 'feeling'' the bottom and then fish a couple of feet away from it trying to draw the barbel out by feeding.Once hooked I don't give them an inch and can normally stop them from getting back to their sanctuary which is what they invariably try to do.
I have the utmost respect for barbel and if a fish was damaged in any way I can assure everyone that I would not practice the hit and hold technique.In my own experience when fishing in this way the barbel has recovered quicker than a long,drawn out fight.
The only time I had one nearly go belly up was years ago in my match fishing days when I hooked an 8.6 on light float tackle,after a 20 minute fight it was exhausted and took an age to recover.
