Bull Redfish: Why the Big Ones Go Back

A red drum can live more than 40 years. It matures at three to six — which, as FWC notes, "typically coincides with their matriculation out of the 27" slot limit."

Read that again, because it is the whole point: the slot is drawn so that a fish grows out of it at almost exactly the age it starts breeding.

Which means every bull red you hook is a spawning adult, and how you handle it matters more than with almost any other inshore fish.

The design behind the slot

FWC states the rule and its reason plainly: Florida requires releasing redfish over 27 inches to protect larger fish, because "redfish don't usually spawn until they get larger than 27 inches."

And it is not simply that big fish spawn — it is that they spawn better. FWC: bigger fish produce superior egg and sperm quality and quantity. Mature red drum are described as prodigious spawners that produce tens of millions of eggs.

So the slot is not a cap on your fun. It is the mechanism that keeps the whole fishery producing, and it does its work precisely at the size that feels most disappointing to release.

The autumn run

This is when most people meet a bull red.

FWC describes mature red drum making annual spawning migrations to coastal nearshore waters each fall, arriving in late August and staying through November. The broader spawning season runs roughly August through December, in passes, inlets and lagoon estuaries.

Two details make it a fishery rather than a fact:

They aggregate. FWC describes large mature red drum gathering in the hundreds to thousands, moving up and down the coast to feed and spawn within a few miles of the shore.

They come to the beach. During autumn, particularly in stormy weather, the big adults push onto the gulf beaches, where they are caught from piers and by surf anglers. That is the bull redfish run, and it is one of the few times a shore angler can reach fish of that size without a boat.

FWC records that spawning begins in autumn when daylight hours decrease and water temperature begins to cool — so this is a photoperiod and temperature event, not a date. Our live conditions tool shows current water temperature at the nearest NOAA station.

Where to stand

• Passes and inlets — the classic staging water, and where FWC places spawning
• Beaches and piers in autumn, especially after a blow
• Jetties where deep water runs close
• Nearshore, within a few miles, if you have a boat

Fish moving water. Read our how to read water page for the reasoning — and note that jetties and piers, the places bull reds are caught from, are also where rip currents form.

Handling, which is the actual skill here

You are going to release this fish. FWC's guidance is unusually specific, and every line of it is worth following:

Keep large fish in the water to reduce stress or injury to the fish.

Always hold them horizontally and support their weight with two hands.

Use wet hands when handling, never a towel or other cloth that can remove their protective slime.

Keep fingers out of the eyes and gills.

Do not drag them over rocks, the gunnel of a boat, the side of a dock or pier, or any other rough surface.

Always revive fish showing signs of exhaustion by allowing a consistent flow of water through the mouth and over the gills.

Do not gaff a fish unless you intend to harvest it.

The dragging one is the one people miss. Beaching a big red on sand or hauling it over a dock edge strips slime and scales along its whole flank, and the slime coat is the fish's defence against infection. If you are surf fishing, keep it in the wash.

Tackle is a conservation choice here

FWC asks for tackle large enough to bring the fish in quickly, reducing the chance of exhaustion, and for single circle hooks that are non-stainless steel, non-offset and barbless.

That is four separate specifications and each does a job: single rather than treble, circle rather than J, non-offset so the circle mechanism works, non-stainless so anything left behind corrodes out. Our hook types page covers why NOAA and the states keep converging on exactly this list.

Light tackle on a forty-year-old fish in warm water is not sport, it is a long fight ending in a fish that swims away and dies later.

The rules are not the same across the Gulf

Same fish, adjacent states, different answers — which is the point our redfish articles keep making:

So a bull red is a mandatory release in Florida and a tagged, once-a-year keeper in Texas. Full detail on Florida and Texas, each checked against its own agency.

Everywhere else writes its own rule again. Check yours.
