Grouper Fishing in Crystal River

Crystal River Grouper Fishing

A Thrilling Adventure for Anglers


A secret too good to keep, shallow water grouper fishing in Crystal River has gained significant attention through television programs and online platforms like YouTube. While locals have known about the nearshore grouper fishery on the west coast of Florida for some time, only recently has it become nationally known. The reason is simple; it makes great entertainment. Casting & trolling lures for a species that is thought to be a deep-water fish is a headline worthy of our favorite clickbait sites. With modern boats, anglers can be at the grouper grounds in minutes and begin scanning the depth finder for the right bottom structure. The abundance of shallow water rock piles and a Swiss cheese bottom comprised of limestone in our area makes it undeniably one of the best places in the state of Florida to target grouper. We will bring you something other than a fishing report for this article. Together we explore the best time to catch grouper, the most effective baits, casting and trolling techniques, tackle recommendations, and the regulations surrounding gag grouper fishing in Crystal River.


What Grouper Are You Catching?


While Florida's west coast has a number of grouper species that anglers target, the one most targeted by us in Crystal River is the Gag grouper. Gag grouper or Gags are a shallow water species of grouper found in the nearshore channels, reefs, and rock piles of Crystal River. Large gags can reach 50 pounds or more, with most keeper-sized fish in the 20-pound range. Gag grouper are revealed for their table fare, and with their average size, they are easily prepared in a variety of dishes.




2023 Gag Grouper Season

Before booking a trip, this is the first question we get asked. Luckily the answer is easy: Always. Grouper can be caught year-round in Crystal River, but the prime time for the best bite occurs during fall. As the waters cool down, large grouper migrate closer to the shore, offering anglers an incredible opportunity to land the fish of a lifetime. From September to December, fishing in the 8-25 foot depth range is ideal, allowing you to enjoy a thrilling experience and bring home some delicious filets. Be sure to check with FWC for legal times to harvest them as it changes yearly. September 1st- November 10th is our 2023 time frame.

Best Grouper Baits

Best Grouper Baits

  • Live Bait

Grouper are known to be attracted to a wide variety of baits; big grouper are rarely picky. However, one bait that consistently entices gag grouper is the trusty pinfish. While pinfish may be the bane of many fisherman's existences, these lively bait stealers are nearly impossible for big Gag groupers to pass up. Pinfish can be caught over grass flats using sabiki rigs or traps, and they rarely fail to catch the attention of other nearshore species like cobia and snook. The most common rig would be the fish finder rig, knocker style rig, or even free lining with a 6/0 – 8/0 circle hook.


  • Dead Bait

In situations where live bait is not readily available, frozen baits such as sardines and threadfin herring can also be effective alternatives. Especially in deeper water or when water temperatures are under 70 degrees. Oily fish work well, so don't throw in the towel if the bait freezer doesn't have your favorites. It's important to remember that smaller fish will start to pick at dead bait. Don't set the hook or start reeling it right away; this nibbling adds more scent to the water and helps draw bigger fish.

Shallow Water Grouper Casting & Trolling

Crystal River is a unique destination for grouper fishing due to the opportunity to cast for these awesome fish. Casting baits for gag grouper is usually performed in water between 8 and 30 feet deep. This shallow depth allows anglers to present their plugs and baits in the strike zone as long as possible. They can also be aggressive enough at times to hit baits on the surface. Casting with large-lipped plugs, jigs, and swimbaits can yield excellent results, provided you use robust hooks capable of withstanding the strength of a big grouper. Among the preferred lipped lures for casting are the Rapala X-Rap Magnum 15, 20, and 30, as well as the FMAG 18. These lures come ready to perform, tracking true in the water, and equipped with sturdy hooks capable of handling the power of a quality grouper. The Magnum X-Rap is simply a scaled-up version of the regular X-Rap, as shown below. The numbers on the Magnum series correlate to the dive depth they are capable of when retrieved or trolled at max speed. This makes figuring out which bait to choose as easy as checking the depth finder. Large paddle tails are very effective as well. NLBN makes some superb grouper jigs & paddle tails that have really upped our casting for grouper game.


Grouper Fishing Charters

Grouper Fishing Tackle

Grouper have a reputation for breaking anglers' lines in structure, pair that skill set with the raw power of these 20-plus pound fish, and you begin to understand the need for a heavy-duty tackle. We recommend using a 65-80 pound braided main line and an 80-100 pound leader to combat their strength. As for reels, the Daiwa BGMQ10000 is a reliable choice that can handle the toughest challenges posed by grouper. The 10000 has more than enough line capacity, even with the relatively thick 80-pound line. The hefty drag and fast receive are real assets for keeping a big fish from running in the rocks and horsing them out when they make a run. Pairing this reel with a 7-foot Daiwa Harrier X rod ensures you have the necessary leverage and strength to conquer these magnificent creatures while still being sensitive enough to cast comparatively small plugs accurately.


Gag Grouper Regulations

It is essential to familiarize yourself with the regulations governing gag grouper fishing to ensure both the sustainability of the species and your compliance with the law. Crystal River's gag grouper season traditionally ran from Jun 1 to Dec 31. However, the harvest dates have changed this year to Open Sept 1. - Nov 10. The minimum length requirement for harvested gag grouper is 24 inches, and each angler is allowed to keep a maximum of 2 fish per person, excluding the captain.

How Do I Eat a Grouper?


We hope you eat one with your mouth. But jokes aside, gag grouper are spectacular for their natural firmness and mild flavor. Grouper can be broiled, fried, or grilled depending on your preference. But it wouldn't be Florida if we didn't suggest a grouper sandwich. Here is our favorite recipe for a simple blackened grouper sandwich.


  • Grouper fillets: You need four skinless grouper fillets, about six ounces each, that are one-half of an inch thick; thicker filets take longer and can be a challenge not to "over blacken."

(Should you want to make this quick, you can buy a store-bought seasoning too. Everglades Seasonings "Fish and Chicken" is a great locally-made choice.)


Blackened spice mix

  • Spices: 

2 tsp of paprika, smoked paprika is preferable but regular is fine too. 

1 tsp each of cayenne pepper, black pepper, ground cumin, garlic powder, onion powder, and kosher salt.

  • Herbs:

 1/2 tsp each dried oregano and dried thyme 

  • Sugar: The secret ingredient in the seasoning. It adds just a touch of sweetness, but it also makes the crust crispy. ½ tsp brown sugar


  • Butter: The butter coats the fish, which helps the seasoning stay put, and the grouper is also cooked in the butter, which adds richness to the dish. I use unsalted butter to not add more salt than is needed.
  • Four Brioche sandwich buns
  • Lettuce
  • Beefsteak tomato sliced
  • Key lime mayo (1/3 cup of mayo, juice of half a lime, a dash or hot sauce to taste)


  1. Begin by heating a cast iron skillet to medium-high on the stove. Make sure there is a window open, or better yet, cook this dish outside to avoid setting off a smoke alarm.
  2. As the cast iron heats, melt your butter in a microwave-safe dish.
  3. Combine your herbs and spices in a separate bowl. Keeping this mixture separate from the fish will allow you to use the seasoning blend on other dishes later.
  4. Dry the grouper with a paper towel and brush with melted butter.
  5. When the pan is hot, add enough butter to coat the bottom of the skillet. Liberally coat each side of the fish with seasoning and place in the hot pan allowing enough room between filets to flip when needed.
  6. Cook on each side for three minutes, four if using a thickened filet.
  7. Remove from heat and place on a toasted brioche bun with lettuce, tomato, and key lime mayo.
  8. Ask for seconds

January-March brings cool weather and full coolers! Starting in January sheepshead move to our offshore rock piles in large aggregations to spawn. No, these aren't the sheepshead species found in the lakes in the northern U.S.. These shrimp devouring scavengers with serious dental work belong to the porgy family, but they put up a nice fight and are great eating. It's really tough to pass up panko crusted sheepshead!

Inshore: Crystal River's inshore waters provide anglers with some outstanding opportunities for the sought-after Florida species like Redfish, Trout, and Snook. Our offshore boat was too big to navigate the shallow waters around the mangrove islands so we remedied that. We are proud to announce the newest addition to our fishing fleet a 20' microdraft. This vessel is designed to be the ultimate fishing boat for exploring the backwaters of Crystal River, Florida. Powered by a Yamaha 90 HP motor, this locally built skiff is designed to run shallower than a flounder. With the ability to float in 3-4" (Inches!) of water at rest and run even shallower, we can access waters that most boats could only access while on a trailer. Unlike many other shallow water boats, this one has an 8-foot main beam, allowing anglers to comfortably fish from a stable platform regardless of where they cast from.
