Caribbean Fishing Techniques

The five methods that matter

Caribbean fishing is not one thing. Most working fishermen use two or three of these methods depending on the season, the boat, and what the market is asking for that week. Knowing when to switch is what separates a full cool-box from an empty one.

• Trolling — offshore, fast-moving pelagics (kingfish, wahoo, mahi, tuna, marlin).
• Bottom fishing — reefs, wrecks and ledges for snapper, grouper, grunts, triggerfish.
• Handlining — the traditional Caribbean method; small boats, low cost, very effective.
• Spinning / inshore — flats, estuaries and shore for tarpon, snook, bonefish, jacks.
• Spearfishing — around reefs for lionfish (invasive, encouraged), snapper, grouper.

1. Trolling — offshore pelagics

Trolling means pulling lures or live baits behind a moving boat, usually at 4–8 knots. It is the standard offshore method in T&T because it covers ground and targets the fast pelagics that command the best prices: kingfish (king mackerel), carite (Spanish mackerel), wahoo, mahi-mahi (dolphinfish), blackfin and yellowfin tuna, and billfish.

When it works

• Pelagic season, October to June. Wahoo especially plentiful in November; marlin peaks around April.
• Over temperature breaks, current lines, weed lines and around FADs (fish aggregating devices).
• Early morning and the change of tide.

Minimum gear

• 4–6 rod spread. Outriggers help if your boat has them; flat lines work if it doesn't.
• Wire trace or heavy mono leader for kingfish and wahoo (their teeth cut mono).
• Spoons, cedar plugs, skirted trolling lures, and/or live baits (hardtail, mullet, ballyhoo).
• Planers or downriggers to get one or two lines deep when the surface bite is slow.

2. Bottom fishing — reefs and snapper country

Bottom fishing drops baited rigs to structure: reefs, wrecks, ledges and drop-offs. It targets the resident species that fill the local market day in, day out — redfish/snapper, grunts, groupers, triggerfish, and pannfish. This is where the depot buyers, restaurants and household buyers are looking for steady supply.

Reading the water

• Anchor up-current of the structure so your chum and baits drift back onto it.
• If you can't anchor (deep water), use a controlled drift or a sea anchor to hold position.
• Fish the edges of the reef, not just the top — the bigger snapper and grouper hold on the drop-off side.

3. Handlining — the traditional Caribbean method

Handlining is the oldest method still in heavy use. A spool of line, a weighted trace, a hook and your hands — no reel, no rod. In the Gulf of Paria and along the south Trinidad coast, handline fishers take kingfish, carite, bonito and shark from small dugouts and pirogues that cost a fraction of a trolled vessel.

Why it still wins

• Cost: a full handline setup is a fraction of a rod-and-reel rig. No maintenance, no electronics.
• Feel: a handliner feels the bite and the bottom directly. You set the hook by hand and you feel a fish turning before a rod tip would show it.
• Fit small boats: works from a 16 ft pirogue where a 4-rod troll spread is impossible.

Typical handline trace

• 50–100 lb mono main line, 200–300 ft for inshore; up to 600 ft for deeper drops.
• Wire trace (12–18 inches) for kingfish, carite and shark — their teeth shred mono.
• Hook: 5/0–8/0 circle or J for kingfish; bigger for shark; snelled.
• Lead: 4–16 oz bank sinker on a snap at the bottom; size to the current.

4. Spinning and inshore — flats, estuaries and shore

Spinning gear is the right tool for inshore gamefish and shore work. It's what bonefish, permit, tarpon, snook and the various jacks (crevalle/cavalli, horse-eye, yellow jack) are caught on. For a working fisherman, inshore spinning is also the easiest way to take visiting friends or a small charter out for a half-day without burning fuel offshore.

Setup

• 6.5–7 ft medium-action spinning rod, 3000–4000 size reel, 10–20 lb braid with a 20 lb fluoro leader.
• For tarpon, go heavier: 8 ft rod, 6000 reel, 30 lb braid, 40–60 lb leader. Tarpon smash light gear.
• Lures: soft plastic shads, small spoons, topwater poppers for tarpon at dawn, live mullet or shrimp.

Where in T&T

• Trinidad is one of the world's best tarpon destinations — the Caroni swamp, the north coast estuaries.
• Bonefish and permit on the Tobago flats (Buccoo, Speyside). Fly fishing is a growing market here.
• Snook and jacks in the estuaries — great shore fishing, low cost.

5. Spearfishing — reefs and the lionfish problem

Freedive spearfishing is the practical form in the Caribbean. Around the reefs it targets the same species as bottom fishing, plus lobster in season. The one exception is lionfish — an invasive species that is actively harmful to coral reefs and is encouraged to be taken by any means, year-round.

Safety and law

• Never spearfish alone. Dive with a buddy and a float with a flag.
• Check local marine park rules — Speyside and Buccoo Reef have no-take zones.
• Recreational spearguns are usually fine; confirm with Fisheries Division before any commercial-volume work.

Picking the right method for the day

The single most useful question is not “what do I want to catch?” — it's “what is the market asking for today, and what can I reach?”

1. Check buyer alerts first. Open Fresh Catch Depot Finder and see who's asking for what. If two restaurants want snapper and one wants kingfish, plan around snapper.
2. Match method to weather and fuel budget. A choppy day offshore wastes fuel and is miserable. That's a handline or spinning day inshore, not a troll day.
3. Match method to season. October–June = pelagic season = troll. Year-round resident species = bottom fish or handline. July–October = peak tarpon/bonefish = inshore.
4. Match method to crew and boat. One person, small boat = handline or spinning. Three people, offshore-capable boat = troll or deep-drop bottom.
5. Keep a catch log. Date, method, location, tide, species, weight, and what it sold for. After three months you'll see your own patterns clearly.

Takeaway checklist

• Troll for pelagics (kingfish, wahoo, mahi, tuna, marlin), Oct–June.
• Bottom fish for the depot staple species — snapper, grunts, grouper (release threatened grouper).
• Handline is the low-cost, high-skill backbone of artisanal Caribbean fishing.
• Spin inshore for tarpon, snook, bonefish, jacks — and for easy half-day charters.
• Spear reef species and lionfish; respect marine park no-take zones.
• Read the buyer alerts before you load the boat. The method follows the market.
