Inside/Outside Shrimp Line

The inside/outside shrimp line is described in state statute and divides Louisiana inshore waters from offshore waters for purposes of managing shrimp seasons.  The inside outside shrimp line begins at the Texas/Louisiana border at Sabine Pass and terminates at the Louisiana/Mississippi state line north of the Chandeleur Islands.
