Does the law really say "that cannot be retained" that makes my hero shots of chum in the canal legal, because I can retain them if I wish.

Different subject Aunty,
Yes, trebles are the tools of snaggers so eliminate them in snagger prone areas. Dont just eliminate them period. Fishing the estuaries of the canal it is not uncommon to only have a couple of bites during a day. I want every chance I can get to make that hookup stick. I have fished side by side with siwash, trebles do hook up more often than the siwash.

Just because it is a treble doesn't mean it has to snag!
