Hmmm ........ tricky one
Must confess that I ( and most folk that I know ) have tried to stick to the River Don Conservation Code, even though to the best of my knowledge this remains "voluntary" in 2007.
In the code you will find:
"No form of live or dead bait (including worm) to be used"
"No ledgering or bubble/bob floats to be used"
Best wishes
