A Louisiana bull red isn’t a bigger version of the slot fish you release in spring. By the time a red drum crosses 27 inches it’s sexually mature and spawning, and it will keep spawning every fall for the rest of a life that can run past 30 years. That biology is why, since June 2024, every fish over 27 inches is a mandatory release in Louisiana. It’s also why the fall marsh fishery is what it is: a shot at old, heavy fish in water barely deep enough to float them, on flies you get to watch them eat.

October through February, the southeast Louisiana marsh gives up mature redfish in skinny water, and Nick Vlahos, writing for MidCurrent, has watched 30-pounders “belly-crawling in less than a foot of water.” The fish are there for months. Whether you can see them, and whether they’ll eat, both ride on the cold fronts moving through, so the smartest thing you can do before booking is understand the weather that runs this place.
