Catching tuna is an exhilarating challenge for any angler. These powerful fish are
prized not only for their fight but also for their culinary value. While many fishing
enthusiasts are familiar with basic techniques, there are lesser-known strategies
that can dramatically increase your chances of landing these giants. Here are ten
valuable and surprising tips for catching tuna that you likely haven’t heard before.
1. Moon Phases Affect Tuna Activity
Most anglers focus on tides and water temperature, but few realize that the moon’s
phases significantly influence tuna behavior. During a full moon, tuna tend to feed
at night, making daytime fishing more difficult. Conversely, during a new moon,
they are more active during daylight hours. Planning your trip around these lunar
cycles can yield better results.
2. Tuna Are Attracted to Sound
While many fish shy away from noise, tuna can be drawn to certain sounds,
particularly those resembling the activity of baitfish. Some commercial fishermen
use underwater speakers that emit baitfish distress calls to lure tuna closer. If
you're trolling, consider adding a rattling device to your lures to create subtle
vibrations in the water.
3. Color Matters More Than You Think
Most anglers understand that lure color matters, but what they may not know is
that different species of tuna respond to different colors based on water
conditions and depth. Bluefin tuna, for example, are particularly attracted to dark
purple and black lures in deep waters, whereas yellowfin prefer pink and
chartreuse in shallower, sunlit areas.
4. Fishing Near Floating Debris Increases Success
Tuna often congregate around floating debris, seaweed mats, and even lost fishing
gear. These objects create micro-ecosystems that attract baitfish, which in turn
lure larger predators like tuna. If you come across debris while out at sea, it’s worth
casting a few lines nearby.
5. Live Bait Selection Can Make or Break Your Catch
Many anglers assume any live bait will do, but tuna can be highly selective. The
best choices are local baitfish that match what the tuna are actively feeding on in
the area. Mackerel, sardines, and squid are excellent choices, but always observe
the local bait schools before making your selection.
6. Using Fluorocarbon Leaders Improves Catch Rates
Tuna have keen eyesight and can detect fishing lines, especially in clear water.
Fluorocarbon leaders are nearly invisible underwater and more abrasion-resistant
than monofilament, making them ideal for fooling sharp-eyed tuna. A leader of at
least 50 to 80 pounds is recommended when targeting larger species.
7. Speed Trolling Works Better Than You Think
While many anglers troll at a moderate pace of 5-7 knots, speed trolling at 8-12
knots can actually trigger a predatory response in tuna. The increased speed
mimics fleeing baitfish, enticing aggressive strikes from fast-moving tuna species
like yellowfin and skipjack.
8. Tuna Respond Well to Chumming – But Timing Is Key
Chumming is a well-known technique, but the secret is timing. Dumping too much
chum at once can overfeed the fish and reduce their interest in your bait. Instead,
throw in small amounts consistently to keep them actively searching for food
without becoming full.
9. Fight Smarter, Not Harder
Tuna are incredibly strong and will test any angler’s endurance. Instead of pulling
straight up, use a “pump and reel” technique—lifting the rod slowly and reeling
down to minimize exhaustion. Additionally, when a tuna is circling beneath the
boat, shift your angle and apply steady pressure to break the pattern and bring it
to the surface faster.
10. Barometric Pressure Affects Tuna Feeding Habits
Many anglers overlook barometric pressure, but it plays a crucial role in tuna
activity. A falling barometer, often signaling an approaching storm, can trigger
feeding frenzies, while a rising barometer tends to slow down their activity.
Checking pressure trends before heading out can help determine the best times to
fish.
Tuna fishing requires patience, skill, and an understanding of the subtle factors that
influence their behavior. By considering these lesser-known tips—from moon
phases and barometric pressure to bait selection and trolling speed—you can
increase your success and land more tuna on your next trip. Whether you’re a
seasoned angler or a beginner, these insights will give you an edge in the pursuit
of these powerful fish.
