Miss. Code Ann. § 49-9-13

The commission shall make such requirements and regulations governing the operations of boats and equipment in the taking of mussels as it may deem best for the proper enforcement of this chapter. To prevent the depletion of the mussel beds and to insure proper propagation of the mussels, the commission may close any beds to operators at any time and for such length of time as it deems necessary. During such closed season on any bed, no one shall take mussels therefrom. When an order is issued closing any mussel bed, notice shall be given as required by law.
