For management purposes, Louisiana’s state waters are divided into inside and outside waters. The “shrimp line” separates these waters. It generally follows the coastline from the Louisiana/Texas state line to the Louisiana/Mississippi state line. Inside waters (landward of the shrimp line) are inshore waters; outside waters (seaward out to three nautical miles) are the territorial seas. Inside waters are further divided by major estuarine basin. The Commission may amend the shrimp line due to environmental changes. See the latest coordinates here.
LDWF, the Commission, and the Louisiana Legislature are responsible for managing the shrimp fishery in inshore waters and the territorial seas. The Gulf of Mexico Fishery Management Council and NOAA Fisheries are responsible for federal waters.
There is no size limit for any shrimp harvested during the spring open season nor for brown or seabob shrimp harvested during any open season.
White shrimp is legal size when a pound of white shrimp equals 100 whole shrimp or less. You may not harvest sub-legal white shrimp, except from October 15 through the 3rd Monday in December. Also, when more than half of your catch is seabob or brown shrimp, no more than 10% (by weight) of your catch may be sub-legal size white shrimp.
You may only use trawls, butterfly nets, skimmer nets, and cast nets to harvest shrimp during open seasons in Louisiana’s waters.
Bycatch Reduction Requirements
Federal law requires all shrimpers fishing with powered or mechanically-retrieved otter trawls (except test nets with headrope lengths of 12 feet or less) to equip them with turtle excluder devices (TEDs), which allow incidentally captured turtles to escape the nets. In lieu of TEDs, shrimpers fishing with test trawls and skimmer and butterfly nets must limit their tow times to 75 minutes from November 1 through March 31 and 55 minutes from April 1 through October 31 to reduce potential impacts on sea turtles.
When fishing in federal waters, shrimp trawlers must install bycatch reduction devices (BRDs) in each trawl to reduce catch of non-targeted species.

|Size and number||
A single stationary butterfly net may measure no more than 22 feet vertically or horizontally.
Individual nets of double butterfly nets may measure no more than 12 feet vertically or horizontally, unless used on a vessel, in which case they may measure no more than 12 feet vertically by 16 feet horizontally.
Double skimmer nets may have an opening circumference of no more than 72 feet for each net and a maximum lead line length of 33 feet.
Butterfly nets may be mounted no more than 24 inches from the side of the vessel.
Skimmer nets may be mounted to the horizontal net frame at any distance from the gunwale of the vessel as long as the mounting distance and horizontal length of the net frame does not exceed 20 feet from the gunwale.
You may not tie individual nets together.
No sweeper devices, leads, extensions, wings, or other attachments.
You must mark butterfly nets with a tag listing your name, address, and net license number when using them in East and West Passes of the Calcasieu River, Grand Bayou, and in Oyster Bayou (all within Cameron Parish only); if found unmarked, these nets will be seized by LDWF agents or other authorized employees. This tag must be attached to the net, frame, or any other part directly attached to the net or frame and must be visible above the water at all times. Letters must be at least 3 inches high and of appropriate width to make it visible and readable.

No stationary shrimp nets within 1,000 feet upstream from another stationary shrimp net that is attached to or moored to a wharf or platform permitted by the Corps. If two permitted wharves or platforms are located within 1,000 feet of each other, the owner of the upstream wharf may attach a stationary shrimp net if:

- Corps permit was issued prior to the permit for the downstream wharf or platform OR
- The owner of the downstream wharf or platform does not open a stationary shrimp net
Only legal nets or trawls attached to a wharf at a camp and tagged with the appropriate LDWF-issued tog may be left unattended.
Shrimper/Crab Trap Interactions
If you catch an unserviceable crab trap, you must keep it on your vessel and properly dispose of it onshore. If you catch a serviceable crab trap without a float, return it to the water with a common float (a white, plastic, one-gallon or larger bleach bottle).
