Yellowfin Tuna

LOCATIONS

BODIES OF WATER

Yellowfin tuna, renowned for their impressive size, speed, and fighting ability, can be found in the vast offshore waters of the Southwest region of the United States. Anglers venture into the deep sea in pursuit of these prized game fish, known for their delicious flesh and thrilling fishing experiences. Here are some typical locations where anglers target yellowfin tuna in the Southwest:
Off the California Coast: Anglers in California have access to productive offshore areas such as the Channel Islands, Cortez Bank, and the offshore banks and canyons off San Diego. These areas are known for their abundance of baitfish and provide prime habitat for yellowfin tuna.

OFFSHORE ENVIRONMENT

Yellowfin tuna inhabit the open ocean and are often found near offshore banks, seamounts, and areas with steep drop-offs. They are highly migratory, following warm ocean currents and chasing schools of baitfish, such as flying fish, squid, and small pelagic species. Yellowfin tuna prefer water temperatures between 70°F and 80°F (21°C - 27°C) and are known for their ability to swim at high speeds.

PATTERNS

SPRING

During spring, yellowfin tuna begin to migrate closer to the coast in search of abundant food sources. Anglers can encounter these fish in offshore waters, particularly around seamounts and underwater structures. Trolling with artificial lures or natural bait, such as live baitfish or rigged ballyhoo, can be effective in enticing strikes from yellowfin tuna.

SUMMER

Summer is considered prime time for yellowfin tuna fishing in the Southwest region. Warm ocean currents bring in large numbers of baitfish, attracting yellowfin tuna in search of food. Anglers often employ techniques such as trolling, chunking, or live bait fishing to entice these powerful fish. Deep-set trolling with diving plugs or using kite fishing techniques can also yield excellent results.

FALL

As the water cools down and baitfish populations remain strong, yellowfin tuna continue their feeding frenzy during the fall. They may still be found in offshore waters, following bait schools or congregating around floating debris. Trolling with a spread of lures or deploying live bait rigs can be effective during this season. Additionally, chunking or chumming with fresh bait to create a scent trail can attract yellowfin tuna to your fishing location.

WINTER

In some regions, yellowfin tuna may migrate out of reach during the winter months, as colder water temperatures push them further offshore or southward. However, in milder climates, anglers may still encounter yellowfin tuna during this time. Monitoring water temperatures, sea surface conditions, and working with local fishing guides can help identify areas where yellowfin tuna may be present during winter.

Yellowfin tuna are known to be voracious feeders and can be targeted using a variety of baits and lures. Common bait options include live baitfish, such as mackerel, sardines, or anchovies, as well as dead bait such as squid, bonito, or skipjack tuna. Trolling with skirted lures, feathers, or cedar plugs can also be effective in attracting strikes from yellowfin tuna.

Trolling

How: Trolling is a popular technique for targeting yellowfin tuna. Use outriggers to spread multiple lines at different distances from your boat. Troll at speeds of 6-10 knots and vary your lure depths to cover different areas of the water column. Yellowfin tuna are often attracted to skirted trolling lures, such as cedar plugs, feather lures, and jet-head lures.
Gear: Rods: Heavy trolling rods with roller guides. Reels: High-capacity conventional reels with a strong drag system. Line: 50-80lb test monofilament or braided line. Lures: Skirted trolling lures in vibrant colors like blue, green, and purple.

Chunking

How: Chunking involves creating a scent trail by periodically throwing chunks of baitfish, such as sardines or mackerel, into the water. Anchor your boat near a productive area, such as a seamount or current line, and set up a chunking station. Use large circle hooks baited with chunks of baitfish and cast them into the chum slick.
Gear: Rods: Heavy spinning or conventional rods. Reels: Powerful spinning or conventional reels with a smooth drag system. Line: 40-60lb test monofilament or braided line. Hooks: Large circle hooks appropriate for the bait size.

Live Bait

How: Yellowfin tuna can be targeted using live bait such as bonito, mackerel, or flying fish. Rig the live baitfish with a bridle rig or a strong hook through the nose or back. Slow-troll or drift the live bait around productive areas, paying attention to any signs of activity on the surface.
Gear: Rods: Heavy spinning or conventional rods. Reels: Powerful spinning or conventional reels with a smooth drag system. Line: 30-50lb test monofilament or braided line. Hooks: J-hooks or circle hooks appropriate for the size of the live baitfish.

Jigging

How: Jigging is an effective technique for targeting yellowfin tuna when they are feeding deeper in the water column. Use heavy metal jigs and drop them to the desired depth. Work the jig aggressively with upward jerks followed by a controlled descent. Yellowfin tuna are known to strike jigs during the fall.
Gear: Rods: Heavy jigging rods with a fast action. Reels: High-capacity conventional reels with a strong drag system. Line: 50-80lb test braided line. Leaders: Fluorocarbon leaders with a high-poundage rating. Jigs: Butterfly jigs, knife jigs, or speed jigs in sizes ranging from 4-8 ounces.
