This year, Louisiana's free fishing days are Saturday and Sunday, June 12 & 13.
It should be noted that while there is no cost (license) required to fish on these days, certain species or types of fishing may still require a permit. For example, a Recreational Offshore Landing Permit (ROLP) is required to possess tunas, billfish, swordfish, amberjacks, groupers, snappers, hinds, cobia, wahoo, and dolphinfish in Louisiana waters.
Speaking of licenses... Louisiana annual fishing licenses for
2020-2021 expire June 30th at midnight, after which you'll need a
2021-2022 license. The new licenses became available on June 1st, and
are good from the time of purchase thru June 30 of 2022.
Licenses can be purchased online at https://la-web.s3licensing.com, or at local license vendors. Acceptable online methods of payment are Visa, Mastercard, and Discover.
