All state inside waters, except Breton and Chandeleur sounds, will be closed to shrimping effective at 6 p.m. Thursday, July 2, the Department of Wildlife and Fisheries announced Monday.

A June 19 inside-waters closure put most of the waters from Freshwater Bayou east to the Louisiana-Mississippi state line off limits to shrimp. Monday’s action closes shrimping in inside waters within the Mermentau, Calcasieu and Sabine rivers basins and waters in Lake Pontchartrain, Lake Borgne, Mississippi Sound and areas in Barataria and Terrebonne bays and Lake Pelto that remained open after that June 19 order.

State marine biologists close inside waters when test-net samples indicate increasing numbers of small white shrimp have moved into inshore areas. Closures allow juvenile white shrimp to grow to marketable sizes.
