The Department of Wildlife and Fisheries has declared an emergency rule closing all commercial and recreational fishing in large portions of Louisiana waters affected by the Deepwater Horizon spill in order to protect existing aquatic life and ensure that no fish harvested for consumption is tainted with hydrocarbons. In addition, the department has closed certain waters to shrimping while instituting a special shrimp season in others. http://www.doa.la.gov/osr/reg/1005/1005.pdf 963-66.
