I've caught barbel on bread since the 1950's, It wasn't only me that was catching on bread, Len Arbery and his mates have caught barbel on bread since the 60's and they still do to this day. I well remember some years ago when Alan Roe joined me on the River Teme, I put him in a hot area with 2 loaves of bread. Lunch time arrives Alan turns up. "Asking if we were going up the pub for lunch" I said "Yes, how many barbel have you had". His answer was nil, not a bite. Are you using bread I asked? No, then that's why your not catching. At the time I was tying on a new hook after losing a fish in a snag.
Having done that I tore off a piece of crust from a fresh loaf, to bait the hook. Alan said "You don't have to put bread on the hook just because of me". My answer was "Its the only bait I have". Having dropped the bait alongside the sedges, I waited all of thirty seconds before I hooked another barbel. Since then Alan has caught barbel on bread, as many other anglers have done. Dick Walker said " A fish will eat anything unless its taught not too" Bread is just another successful bait. As are pellets, boilies, worms, gentles, sausage paste, cheese and many other food items. As with all baits I reckon the more confidence you have the better will be your results. Its not the best or worse bait. Its just another food item that barbel like. Regards Martin
