How to jig yellowtail in Southern California (deep yo-yo and tuna jigs)
SoCal yellowtail eat metal when you put the right iron on the right mark. Deep stacks under the boat want a vertical drop-and-wind. Birds, boils, and kelp edges want surface iron or bait. Match the tool to the meter, not the brand on the bag.

I care about this because the same San Diego trips that mark bluefin also mark yellows, and the deep vertical window is where a lot of day-boat rails actually spend their time. I am not inventing a dated yellowtail catch or size here. What follows is how to find them, how they behave, which iron to throw, and when a heavy tuna jig earns a spot next to classic yo-yo and surface iron.
How do you find yellowtail in Southern California?
Start with structure and the meter, not hope.
- Banks, canyons, and island edges: classic SoCal yellowtail water. Captains work contours where bait holds and current licks the edge.
- Deep kelp edges: fish can sit under or just off the fringe. Shallow inside the kelp is often a different, lighter game.
- Meter marks under the boat: hard arches or a stacked cloud at a called depth. That is your vertical window.
- Birds and boils: surface life means fish (or bait) are up. That is surface iron / bait territory until the school goes down again.
Public writeups in Western Outdoor News, Pacific Coast Sportfishing, Saltwater Sportsman, and Kayak Angler all circle the same split: fish marked deep under the boat versus fish showing on top. Do not force one presentation into both jobs.
What conditions put yellowtail in range?
I am not forecasting your next weekend. These are verified seasonal and condition themes anglers already use on the SoCal coast:
- Current: a moving tide often helps the bite under the boat, and it also increases line scope. More current usually means more weight or shorter drops. See Why Your Jig Isn't Getting Bit: Line Scope, and How to Stay Vertical.
- Wind and swell: tough seas shrink the fleet and change drift. If the boat cannot hold a clean column over the mark, the iron never gets a fair look.
- Water and bait: clear blue with bait on the edge is the story captains chase. Green or empty water can still produce on a known rock, but the meter matters more than hope.
- Seasonal SoCal pattern (general, not a guarantee): yellowtail are open year-round in the Southern management area. Warm-water stretches and summer/fall island and bank trips are when more boats are actively hunting them; winter can still produce for anglers willing to fish deep marks and slower days (Kayak Angler and regional reports describe winter fish holding deep and eating on the drop).
Pack for the fish on the board that day. If the same boat is also marking bluefin, do not under-gun the rail.
How do yellowtail behave under the boat?
When yellows are marked under the rail, public yo-yo and iron writeups describe a consistent picture:
- Hold deep: on bottom, or suspended tens of feet off bottom (Western Outdoor News notes yellows often on bottom or up to about 50 ft off bottom when you are yo-yoing).
- Eat on the fall and on a hard rise: bites show as a stop, a tick, or slack. Treat sudden weight as a fish until proven otherwise (Pacific Coast Sportfishing deep-water yo-yo notes; Kayak Angler on strikes through marked fish on the drop).
- Stay in the zone: wind through the holding band, not necessarily all the way to the surface every time (Saltwater Sportsman deep yellowtail / iron works). Drop back into the mark and work it again.
- Surface boils are a different game: fish eating in the top 20-40 ft want surface iron or bait, not a 300-400g sinker falling past them.
What techniques actually catch them?
Deep yo-yo / drop-and-wind
This is the under-boat play.
- Drop to the called mark or to bottom if that is where they are stacked.
- Engage and wind hard for about 15-20 cranks, or through the marked layer, then drop back into the zone (Pacific Coast Sportfishing deep-water yo-yo pattern).
- Watch the line on the sink. Bites on the fall count.
- When the angle opens past roughly 15-20 degrees off vertical, wind up and re-drop. Do not fish out a scoped line.
Heavier metal helps you stay vertical when current pushes the braid (Western Outdoor News yo-yo tips). Fast retrieves trigger; slow aimless winding usually does not (Saltwater Sportsman).
Surface iron and kelp / boil fishing
Long casts, burns across the top, and fly-lined live bait still catch plenty of yellowtail around paddies, birds, and kelp edges. A heavy tuna jig is the wrong tool here. It is awkward to cast all day and spends too much time below fish eating high.
Which iron should you throw?
Honest matching, not brand loyalty.
| Situation | Tool that usually fits |
|---|---|
| Mid-depth structure, classic yo-yo all day | Salas / Tady-style yo-yo iron in the few-ounce class |
| Shallow rock, light current, fish high | Lighter yo-yo iron; do not overshoot the mark |
| Birds, boils, kelp edges, surface life | Surface iron (Tady-style casting irons) and/or live bait |
| Deep mark under the boat, current, same box as bluefin gear | Heavier vertical tuna jig (250-400g) |
A tuna jig is not a Salas 6X or a Tady 4/0 Heavy. Different profile, usually more weight. The job overlap is vertical, deep, under the boat.
Weight starting point when you do go heavy: roughly 1 g per foot of depth, same logic as bluefin. Full breakdown: What Size Jig for Bluefin Tuna? Use the Gram-to-Foot Rule.
| Mark / depth | Slack to moderate current | Heavy current or fast drift |
|---|---|---|
| ~100-250 ft | 250g | 300g |
| ~150-300 ft | 300g (~10.6 oz) | 350-400g |
| ~200-400 ft | 350-400g | 400g (~14.1 oz) and stay vertical or reposition |
Depth in ft, line in lb, jig weight in g (how tuna jigs are sold) with oz noted once. Do not mix catalog "ounces of iron" with gram labels and expect the same fall.

What are the California yellowtail rules right now?
Verified against the CDFW Southern California ocean recreational summary (page note: updated September 1, 2026) and 14 CCR §28.37:
- Open year-round in the Southern management area (Point Conception to the U.S.-Mexico border).
- Daily bag and possession: 10 yellowtail.
- Minimum size: 24 inches fork length, except that up to 5 fish under 24 inches fork length may be taken or possessed.
Always re-check CDFW's Southern regs map page before a trip. Mexican waters and long-range itineraries can stack different rules. Do not assume CDFW numbers travel with you.
FAQ
Can you catch yellowtail on bluefin / tuna jigs?
Yes, when yellowtail are marked deep under the boat and you fish a vertical drop-and-wind. Surface boils and shallow kelp still favor surface iron and bait.
What jig weight for yellowtail in 200 ft of water?
About 200-300g in mild current; step toward 300-400g if the line scopes or the drift is hard. Gram-per-foot is a starting point, not a promise.
Is yo-yo iron better than a tuna jig for yellowtail?
For mid-depth structure and all-day yo-yo with lighter irons, classic Salas/Tady-style yo-yo iron is still the standard. A tuna jig fits when you need more weight, the same box as your bluefin gear, or a deeper / current-heavy mark.
Do I need glow for yellowtail on jigs?
Not settled. Day yellowtail often eat chrome, blue/white, and baitfish patterns. Glow matters more after dark. Keep the drop vertical first.
What is the yellowtail bag limit in Southern California?
10 fish daily, 24 in fork length minimum, with up to 5 under 24 in allowed. Confirm on the current CDFW Southern ocean regs page before you keep fish.
Find the fish, match the iron to the meter, kill the scope, wind like you mean it. When the mark is deep and current is up, the heavy pair I keep in that role (when tungsten is sold out) is the 
Torpedo Duo (300g + 400g). Soft fit only. Classic yo-yo and surface iron still own their own windows.
