The Gulf of Mexico commercial shrimp season for both state and federal waters will open 30 minutes after sunset Monday.

The opening date is based on an evaluation of the biological, social and economic information to maximize the benefits to the shrimping industry and the public.

Texas Parks and Wildlife Department Coastal Fisheries Division use scientific information to determine when to open the season, including samples collected by using trawls and bag seines in TPWD routine data collection.

The purpose of the closed Gulf season is to protect brown shrimp when they move from the bays to the Gulf of Mexico until they reach a larger, more valuable size before harvest and to prevent waste caused by the discarding of smaller individuals.
