Overview
Striped marlin are Pacific and Indian Ocean billfish known for acrobatic jumps and a tall, pointed dorsal fin. Well-known fisheries include Baja California and Magdalena Bay in Mexico, Ecuador and Peru, Hawaii, New Zealand and eastern Australia. Techniques vary by location, but most anglers rely on trolling to find fish and then switch to bait or a pitched presentation to get a hookup.
Finding fish
Look for temperature breaks, current edges, bait balls and birds, as covered in how to know where fish are. Striped marlin often feed near the surface, and finning fish can sometimes be spotted. Local captains and recent reports are the best guide, because fish location changes with water temperature and bait.
Trolling lures and baits
- Lures: Skirted lures in a range of colors, run at different distances behind the boat, are a classic way to cover water. Many anglers use smaller lures than for blue marlin, though choices vary by region.
- Rigged baits: Skipping and swimming baits such as ballyhoo, mackerel, squid or mullet are widely used.
- Spread: A typical spread mixes lures and baits at staggered distances, with teasers positioned to attract fish into the pattern.
Trolling speed depends on the baits, and many boats troll at modest speeds. Follow your captain’s lead for local best practice.
Teasers and bait-and-switch
A common method is to raise a fish with teasers (often a daisy chain of squid or mackerel, or a lure with no hook), then pull the teasers away while pitching a baited line into view. The fish sees a free meal and often takes it. This works well because the fish is already excited and committed. It requires communication: the mate watches the teaser, the angler holds a rod ready, and the captain controls the boat speed.
Live bait and dead bait
Live baits such as mackerel, sardines or small tuna may be drifted or kite fished in some areas, and they can be effective for fish that are not reacting to teasers. Dead baits and strip baits are also used, especially around bait concentrations. Where regulations allow, circle hooks are widely used for baited fishing because they tend to hook in the corner of the mouth and make release easier.
Rigging and hooks
Use fresh, strong leader and check your knots and crimps (see how to make saltwater leaders). Leader strength varies with fish size and region. Circle hooks suited to the bait are common. Let a pitched bait drop back, give the fish time to take it, and then apply steady pressure rather than a violent strike. This helps a circle hook set properly.
Tackle
Many striped marlin anglers use stand-up conventional gear or sturdy spinning tackle in a light-to-medium line class, sometimes lighter in calm conditions or heavier where bigger fish are expected. Fish are often released, so match tackle to keep fights reasonable. Gear preparation, such as checking rods, drag settings, line and leader, is essential before leaving the dock, and dress for a long day on the water (see what to wear for deep sea fishing).
Hooking, fighting and release
After the fish takes the bait, wait as instructed, then tighten gradually. Expect jumps and runs. Keep the line tight, keep the boat positioned to follow the fish, and use a smooth drag. For release, keep the fish in the water, remove the hook quickly, and revive by moving slowly forward so water passes over the gills. Many fisheries and tournaments have catch-and-release rules or limits, so check local regulations.
Striped marlin versus blue marlin
Striped marlin generally have a taller, more pointed dorsal fin and a visible pattern of stripes, and are typically smaller than blue marlin, which are among the largest billfish. Blue marlin have a lower, more rounded dorsal fin and a heavier build. Details vary, so a captain or guide can help you identify what you caught.
