Economic Impacts of Coastal Hazards on the Mississippi Oyster Fishery

More than 13 years ago, Hurricane Katrina devastated the coastal areas in the Northern Gulf of Mexico in August 2005. The closures of significant portions of Gulf waters to commercial and recreational fishing due to the Deepwater Horizon (DWH) oil spill in April 2010 altered the production, recreation, and consumption decisions of households and businesses in affected communities.

Mississippi was in the process of restoring the public oyster reefs after H. Katrina and the DWH oil spill when the Bonnet Carre Spillway (BCS) opening in 2011 resulted to massive oyster mortalities in the shellfish growing waters. These mortalities halted the recovery process of the oyster fishery to its baseline levels in 2002-2004. The prolonged exposure to freshwater which caused massive mortalities of the oyster populations required restoration projects to enable the fishery to recover to its baseline status.

The restoration efforts included but not be limited to the dredging of non-affected oyster seed stock and relaying them to affected reefs. Oyster shells and other cultch materials were purchased and planted in affected areas. These restoration efforts were expected to replenish the damaged oyster populations in public reefs.

Recent natural and technological disasters and coastal events affecting the oyster fishery:

Long-term data were compiled to develop economic recovery models (ERM) for oyster harvesting. The ERM explains the individual and joint effects of the recent natural and technological disasters, output and input markets, environmental conditions, and regulatory and management strategies on the levels of commercial oyster harvests and dockside values.
