This bylaw was brought in to stop potters using White faced crabs(edibles that have peeled and are no good to eat as they are full of water) as bait for Lobsters.
I worked on a coble out of Seaham in the 70,s and early 80,s and this was common practice till the bylaw came into affect.
There are only a few Defra inspectors to cover our region, which is from the Humber to Berwick and they are more bothered with the boats than us anglers.
I don,t think they will waste there time scouring the coast for anglers using Cart as bait.
