Mississippi Code Title 49. Conservation and Ecology § 49-15-36

(1) The Department of Marine Resources shall have full jurisdiction and control of all designated state-owned reefs and oyster bottoms of the State of Mississippi. In no event shall the department designate more than twenty percent (20%) of the permitted areas available as state-owned reefs.

(2) State-owned reefs may be opened for harvest of oysters during the season on a rotating basis. If the department determines that a particular reef has been overharvested or that a high percentage of sublegal size oysters exist on a particular reef and that harvest could damage future oyster crops, the department may close designated reef areas and keep them closed during the season.

(3) The department shall promulgate regulations regarding the closing of oyster reefs to protect the public health. When that testing indicates the oysters on the closed reef are suitable for consumption, the reef shall be opened for the taking of oysters as soon as notice of that opening may be made to interested parties. The authority to open or close oyster reefs under this chapter shall be solely within the discretion of the department. The Gulf Coast Research Laboratory or other certified laboratory shall cooperate with the department and shall conduct necessary tests to determine the condition of oyster reefs at the request of the department. The department may limit the sale of oysters for human consumption.

(5) The department shall establish a reasonable period of time for depuration of oysters replanted from restricted waters. That period of time shall be consistent with the maintenance of the public health and may vary from time to time and from one reef to another in accordance with environmental conditions.
