Louisiana Revised Statutes Tit. 56, § 329. Obstruction of streams or lakes by fyke nets or other devices

B. (1) Except as provided in Paragraph (2) of this Subsection, no obstructions including trawls, skimmer nets, butterfly nets, fyke nets, wings or leads, seines, gill nets, or trammel nets which interfere with the free passageway for fish as defined in this Section shall be set within five hundred feet of the mouth of any inlet or pass, or within five hundred feet of any water control structures, dams, or weirs, except for the purpose of retaining and removing invasive species of fish and other nongame freshwater fish of commercial value. When fishing for the purpose of retaining and removing invasive species of fish and other nongame freshwater fish of commercial value, nets are restricted to a mesh size no smaller than three and one-half inches bar. Wings and leads are permitted on hoop nets in overflowed regions where the water is out of the actual bed of the natural stream or lake but not within the restricted five-hundred-feet area.

(2) Notwithstanding the provisions of Paragraph (1) of this Subsection, hoop nets set in Little River in Grant Parish and LaSalle Parish may be set closer than five hundred feet to the mouth of any inlet or pass or water control structure, dam, or weir.
