No Rod, No Reel, No Problem: A Spearfisherman’s Guide to Stalking and Stoning Trophy Tuna in Open Water

The world goes silent. All you hear is the slow, rhythmic beat of your own heart and the faint hum of the deep blue. Below you, a thousand feet of nothing. Then, a flicker in the periphery. A shadow materializes, growing from a ghost into a torpedo of muscle and speed—a massive yellowfin tuna. The adrenaline hits you like a linebacker, a primal surge that connects you to every apex predator that has ever hunted these waters. This isn’t fishing. This is the hunt.

For most, this is a once-in-a-lifetime dream. For Captain Troy Wetzel of Louisiana Offshore Fishing Charters, it’s another day at the office. With over 20 years of experience dominating the Gulf, holding both state and world records, his singular passion is putting clients on the biggest fish in these waters, whether by rod or by spear. This guide isn’t just theory; it’s a look into the methods Captain Troy has perfected for stalking and stoning trophy tuna, transforming a great fisherman into an underwater hunter.

Why Trade the Rod for a Speargun? The Primal Appeal

You’ve done it all. You’ve felt the screaming run of a wahoo, battled marlin, and filled the fish box with snapper. The thrill of the fight on a line is one thing, but it’s a remote battle. Meeting a 150-pound tuna on its own terms, in its own world, is a completely different game. This is the evolution from angler to hunter.

You’re no longer waiting for a bite; you are actively seeking, stalking, and choosing your prey. The mindset shift is total. There’s no boat deck, no fighting chair, no complex system of reels, lines, and lures. It’s just you, your gear, and the fish in the vast, silent blue. This is the most unfiltered connection you can have with the marine environment—a pure test of skill, nerve, and instinct.

The Hunt: Captain Troy’s Method for Stalking Trophy Tuna

Success out here isn’t luck. It’s the result of a brutal, unforgiving process of elimination perfected over two decades. Here’s how we get it done.

Step 1: Gearing Up for Battle (Not Just a Fishing Trip)

You don’t bring a knife to a gunfight, and you don’t bring a reef gun to a tuna hunt.

• The Right Tool for a Giant: We’re talking about high-powered, blue-water spearguns. These are multi-band, enclosed-track cannons designed to punch a heavy shaft through a thick-bodied, powerful fish at a distance. The power is non-negotiable; you need enough force to penetrate deep and anchor your shot.
• The Rigging is Everything: This is a critical safety component. We use breakaway rigs. When you shoot, the spear shaft detaches from the gun and is connected directly to a float line and a series of high-pressure floats. This system ensures that when that tuna sounds for the deep, it’s not taking you with it. The fish fights the floats, not the diver.
• Personal Gear is Survival Gear: Your mask, fins, and snorkel are your life support. A low-volume mask is essential for conserving air on your descent. Long, powerful fins are your engine. Your wetsuit isn’t just for warmth; it provides camouflage and protection. Every piece of gear must be top-quality and fit perfectly.

Step 2: Finding the Arena – Reading the Open Water

Your fish finder is a tool, but it’s not the whole story. The real art is in navigating nature’s fish finder. Twenty years of running fishing charters out of Venice, LA, gives you a sixth sense for where the fish will be.

• Signs of Life: We’re looking for birds working the surface, bait balls getting smashed, and distinct temperature breaks in the water. In the Gulf, floating structures are magnets for life. The massive oil rigs are vertical ecosystems that hold bait, which in turn holds predators like yellowfin tuna.
• Positioning the Boat: Setting up the drift is everything. I don’t just drive up to a spot and tell you to jump. I analyze the current, the wind, and the position of the fish. The goal is to position my 39′ Contender offshore boat so you can drift silently into the strike zone without the boat spooking the school.

Step 3: The Silent Stalk – How to Approach a Wary Giant

Tuna are not stupid. They are wary, powerful predators with incredible eyesight. A clumsy approach will send them into the abyss before you even see them.

• Entering the Water: No cannonballs. You slip into the water with minimal splash and noise.
• Body Language is Key: Once you’re in, you become part of the environment. You stay horizontal on the surface, controlling your breathing to remain calm and conserve oxygen. Movements are slow, deliberate, and fluid. You never, ever make direct eye contact. Staring is a sign of aggression in the wild, and a big yellowfin will read it as a threat and vanish.
• Using the Environment: We use the sun to our advantage, keeping it at our back to stay hidden in the glare. We use the current to drift into range, minimizing movement. The goal is to appear non-threatening until the absolute last second.

The Shot: What it Means to “Stone” a Trophy Tuna

Getting close is only half the battle. The shot itself is a moment of absolute precision. The difference between a trophy on the boat and a dangerous, gut-wrenching rodeo comes down to a few inches.

Understanding Tuna Anatomy

Stoning: This is the goal on every single drop. A “stone shot” is a perfect shot that instantly kills the fish by hitting the brain or severing the spinal cord. The fish goes rigid, its fins flare, and it sinks. It’s the most ethical and safest way to land a big fish.

A body shot, by contrast, is a recipe for disaster. A gut-shot tuna will take off on a “death run,” pulling your floats under and dragging you on a dangerous chase that can last for miles and attract sharks. We don’t take body shots.

Patience and Precision

The urge to pull the trigger when a 150-pound fish swims into view is immense. You have to fight it. This is where having an experienced guide in the water with you is critical. I’m there to help you read the fish’s body language, to tell you when to wait for a better angle, and to identify that split-second window when the perfect shot presents itself. Patience is the difference between a story of a lifetime and a story of the one that got away.

After the Shot: The Fight is Different

When you stone a fish, the fight is one of controlled power. It’s about managing the float line, keeping tension, and working as a team with the boat. My job is to maneuver the vessel to help you, keep other divers safe, and be ready to gaff and land the fish once you bring it to the surface. It’s a coordinated dance that requires communication and trust.

Safety First: The Non-Negotiables of Blue Water Spearfishing

Let’s be clear: this is an extreme sport. The open ocean is unforgiving. It demands respect and an unwavering commitment to safety. This is the single biggest reason you go with a professional charter.

• The Buddy System is Law: You never, ever dive alone. Period. We operate with an in-water spotter and the captain on the boat, whose eyes are always on the divers.
• Understanding Shallow Water Blackout: Breath-hold diving carries inherent risks. We brief every diver on these risks, emphasize the importance of proper breathing techniques, and stress that you never push your limits. This isn’t a competition to see who can stay down the longest.
• Sharks and Other Marine Life: Yes, there are sharks in the ocean. We are in their house. An experienced captain knows how to manage these encounters. It’s about situational awareness, respect, and understanding animal behavior. Panic is dangerous; calm, confident experience keeps everyone safe.
