Existing data do not currently support shrimping closures in additional state inside or outside waters. However, historic data suggest additional closures may be needed in the near future and the Department of Wildlife and Fisheries will continue monitoring shrimp populations in these waters.
 
Regulations state that the possession count on saltwater, white shrimp shall average no more than 100 (whole shrimp) count per pound, with the exception of October 15 through the third Monday in December, when there is no minimum count size.
 
The Louisiana Wildlife and Fisheries Commission provided LDWF Secretary Robert Barham with authority to close both the fall inshore shrimp season and shrimping in the state’s territorial sea when biological and technical data indicate the need. Recent sampling conducted by the LDWF Fisheries biologists indicates that average white shrimp size in those waters to be closed is smaller than the minimum possession size limit. This action, which characteristically takes place at this time of year, is designed to protect small, white shrimp and provide opportunity for these populations to over-winter and grow to larger, more marketable sizes.
 
Louisiana continues to lead the country in shrimp landings. In 2013, approximately 5,300 licensed Louisiana commercial shrimpers landed 98.8 million pounds of shrimp (all species combined/heads-on weight) that had a dockside value of $178.3 million.
