22 Miss. Code. R. 13-4.1
Net-pen or other containment systems for culturing finfish, crustaceans or other non-molluscan marine organisms shall be located in waters of sufficient depth. A minimum clearance of ten (10) feet below the bottom of the net-pen system shall be maintained at all times. The distance shall be measured at mean low water. If monitoring indicates a serious problem with water quality or other environmental conditions at the site (i.e., when certain limits for specific parameters established in the monitoring program or by the Mississippi Department of Environmental Quality are exceeded), the operation must be adjusted to reduce impacts.
Adjustments shall include, but are not limited to, modifying the feeding rate or feeding schedule, reducing the amount of fish in the net- pen system, or increasing or decreasing the clearance under the nets to allow for increased water circulation.
