Marine and Coastal Access Bill [HL]

I am wondering whether the setting of lobster pots would require a by-law. The part of the coast that I am thinking of is not one to which the Bill applies. However, there must be areas in the inshore waters where small businessmen, in a small way, in small boats, regularly set lobster pots very near the coast. Would that disturb a conservation zone? Would that be something for which a by-law would be required—not an emergency one, but one under the other clause?
