September is gag grouper season on Florida’s Gulf Coast.

For 2026, the season is open from September 1 through September 30. That gives anglers a short window to target one of Florida’s hardest-fighting fish.

The good news is there are many ways to catch them. You can cast plugs in shallow water, troll over rock piles or drop live bait offshore.

No matter how you fish, you need strong gear. A gag grouper’s first move after getting hooked is usually straight back toward the rocks.

Start With a Strong Setup

The Tsunami Carbon Shield III Boat Spinning Rod is a great choice for grouper fishing. It is light enough for casting but has the backbone needed to turn a big fish.

Pair it with an Evict II or Shield II, depending on how you plan to fish.

Both reels have all-metal bodies, sealed drag systems and IPX6 sealing with 12 internal seals. This helps protect the reel while fishing around saltwater, spray and rough conditions.

Casting Plugs and Swimbaits

Shallow-water grouper fishing can be some of the most exciting fishing on the Gulf Coast.

Areas like Crystal River have rocks, ledges and hard bottom that hold plenty of gag grouper. Instead of dropping bait straight down, anglers can cast large plugs and swimbaits across the structure.

A great setup is a 7' Medium-Heavy Carbon Shield III paired with an Evict II 5000 or 6000.

Start with a diving plug and work it fast across the rocks. If the plug bite slows down, switch to a large paddle-tail swimbait.

When a grouper eats, start cranking right away. Your goal is to turn the fish before it gets back into the rocks.

Trolling for Grouper

Trolling is another great way to find gag grouper.

Use your sonar to find rock piles, ledges, reefs and other hard bottom. Then troll a diving plug close to the bottom.

You want the lure swimming just above the structure.

For trolling, try a 7' Heavy Carbon Shield III with a Shield II 6000 or 8000.

The larger Shield II reels give you more line, strong gearing and plenty of drag for stopping a grouper before it reaches cover.

This is a great way to cover water around Tampa Bay, Crystal River and other areas with shallow structure.

Fishing Live Bait

When plugs and swimbaits stop getting bites, switch to live bait.

Pinfish and grunts are great choices.

A Carbon Shield III Heavy with an Evict II 6000 or Shield II 6000 gives you the power needed to pull fish away from structure.

Try 60- to 80-pound braid with 60- to 80-pound fluorocarbon leader. The heavy leader helps protect against rocks and other sharp bottom.

The same idea works offshore. Use enough weight to reach the bottom and be ready to pull hard when the fish eats.

Three Simple Grouper Setups

Fish Fast and Move Often

Gag grouper are ambush predators. They like rocks, ledges, wrecks, and other structure where they can wait for food.

Find good bottom and fish it hard.

Start with plugs. Move to swimbaits. Try live bait when the bite slows.

If the fish stop biting, move to the next spot.

Whether you're trolling Tampa Bay, casting plugs around Crystal River or dropping bait offshore, the Carbon Shield III paired with the Evict II or Shield II give you the power needed to get big gag grouper away from the rocks.

September is here. Gear up and take advantage of the 2026 Gulf gag grouper season while it lasts.
