The Basics: Why Trolling with Lures Works
Trolling works because it simulates a baitfish or squid swimming through the water. Predator fish, always on the lookout for easy prey, can’t resist the movement and flash of a well-trolled lure. Unlike stationary fishing, trolling keeps you moving, so you can cover more ground, follow bait balls, and find feeding fish.
Types of Trolling Lures
The variety of trolling lures available today is staggering. Each is designed to mimic a different kind of prey or provoke a strike using color, motion, and vibration. Here are the main types used in Costa Rica:
1. Skirted Lures
Skirted lures, often called trolling skirts, are a staple in offshore fishing. They consist of a shaped resin or metal head and a long, colorful skirt made from synthetic material. These skirts flow naturally in the water and attract species like marlin, sailfish, and wahoo.
- Key features: Weighted heads, flashy skirts, large eyes, often run without bait.
- Top targets: Marlin, sailfish, tuna, wahoo
- Best speeds: 6 to 9 knots
2. Soft Plastic Lures
These lures resemble baitfish, squid, or eels, and their soft body allows for realistic movement. Often paired with jig heads or run behind skirted heads, soft plastics can be deadly inshore or offshore.
- Top targets: Kingfish, sailfish, mahi-mahi, bluefish
- Best speeds: 3 to 7 knots
3. Diving Plugs (Crankbaits)
These are hard-bodied lures with a plastic lip that causes them to dive and wobble as they move. They mimic wounded baitfish and can be set at specific depths.
- Top targets: Tuna, wahoo, king mackerel, dorado
- Best speeds: 4 to 8 knots
4. Surface Lures (Poppers & Stickbaits)
Designed to create surface commotion, these lures are great for enticing fish feeding near the top.
- Top targets: Tuna, mackerel, mahi-mahi
- Best speeds: 3 to 6 knots or worked manually
Trolling Setups: Gear That Gets It Done
Rod and Reel
Use a trolling rod with enough backbone to handle big fish. A 30-50 lb class rod paired with a two-speed reel like a Penn International or Shimano Tiagra is ideal. The reel should have a smooth drag system and plenty of line capacity.
Line and Leader
- Main line: Braided or monofilament line rated for 30-80 lb
- Leader: Fluorocarbon or wire leader, depending on the species
Use longer leaders (6-10 feet) for clear water and wary fish. For toothy species like wahoo, a wire trace may be necessary.
Outriggers, Downriggers & Planers
To avoid tangles and cover more horizontal space, use outriggers to spread lures wide. Downriggers or planers can be used to troll lures at deeper depths, ideal for targeting tuna or bottom-feeding pelagics.
Spreader Bars and Teasers
These tools mimic bait balls. Spreader bars feature multiple lures strung across a frame, while teasers are large, flashy attractors that draw attention to your spread.
Trolling Techniques
Trolling Speed
Speed affects how your lure behaves. Some lures, like deep-diving plugs, need slower speeds to work properly. Others, like skirted lures, handle higher speeds well.
- General range: 4 to 10 knots
- Experiment: Watch how each lure swims, and adjust speed accordingly
Trolling Patterns
Trolling isn’t just straight lines. Try patterns like:
- V-pattern: Lures staggered at different lengths to cover a wide area
- W pattern: Adds more cross-action in the spread
- Shotgun lure: A single lure placed far behind the spread often catches shy fish
Depth Control
To fish multiple layers of the water column:
- Use different lure types (surface, mid-depth, deep)
- Employ planers and downriggers
Tips for Trolling Success
1. Observe Your Surroundings
Watch for birds, bait balls, and color changes in the water. These are all signs of fish activity. Fish often follow temperature breaks or current edges.
2. Maintain Lure Action
Check your lures regularly to ensure they’re swimming properly. A tangle or fouled lure can waste your whole spread. Replace damaged skirts and dull hooks.
3. Use Fresh, Sharp Hooks
Even the best lure won’t work if your hooks are dull or rusty. Always start with sharp hooks, and replace them as needed.
4. Match the Hatch
If you see flying fish, sardines, or squid in the area, match your lure size and color to them. Fish are more likely to strike something familiar.
5. Don’t Be Afraid to Change It Up
Sometimes, all it takes is swapping out one lure color or adjusting your trolling speed to start getting bites. Don’t get stuck in one pattern.
Trolling in Costa Rica: What to Expect
Costa Rica is one of the world’s top trolling destinations. On any given day, you can hook into:
- Blue Marlin: Best near FADs (Fish Aggregating Devices)
- Sailfish: Peak season December to April
- Yellowfin Tuna: Often found with spinner dolphins
- Mahi-Mahi (Dorado): Year-round, but best October to December
- Wahoo: More common around the structure or during the rainy season
Local captains use years of knowledge to adjust spreads, switch lures, and follow the bite. Many use live bait teasers and run 5-9 lines in a well-managed spread.
Safety Considerations
- Secure all hooks and gear: Lures with multiple hooks can be dangerous
- Wear gloves when handling leaders
- Keep gear organized to avoid tripping or tangling
Final Thoughts: Why Trolling with Lures is a Game-Changer
Trolling with lures is more than a fishing method—it’s a high-speed chess match between angler and predator. It gives you the flexibility to adapt, move, and strike when the opportunity presents itself. With the right knowledge, gear, and strategy, your chances of landing a trophy fish go up dramatically.
Whether you’re heading offshore from Jaco, Herradura, or Quepos, trolling with lures can unlock some of the most exciting and rewarding fishing Costa Rica has to offer. So gear up, fine-tune your spread, and get ready to experience the thrill of trolling at its finest.
