Worth looking back at some old posts, been alot of trouble in the past from crab collecting. Bit of a war in some areas as it is a second income for some people and its not easy setting, cleaning traps etc.
Just make sure if you do go out collecting that you are not in peoples tyres etc, this whole issue popped up last year about "they not peoples tyres" etc.
Anyway look at past posts, not worth the bother in my opinion on this coast.
