Up in our neck of the woods the regulations are quite clear, but what do they mean. The definition of bait is;
- any foodstuff or natural substance used to attract fish, other than wood, cotton, hair, fur or feathers. It does not include finfish other than roe. It includes roe, worms and other edible substances, as well as scents and flavourings containing natural substances or nutritents.

Now I just need someone to define what a natural substance is. ..WD40?
