If you're looking to fill the cooler, trolling spanish mackerel is honestly one of the most effective ways to spend a morning on the water. These fish are fast, aggressive, and they travel in massive schools, which means once you find one, you've usually found a hundred. The best part? You don't need a massive offshore sportfisher to get in on the action. Whether you're in a center console, a skiff, or even a sturdy kayak, you can get some serious meat in the boat if you know the right tricks.
Speed is your best friend
One of the biggest mistakes I see people make when they start out is going too slow. Spanish mackerel are built like little silver torpedoes, and they live their entire lives at a sprint. If your lures are just lazily drifting through the water at three knots, a mackerel is going to look at it, realize it's fake, and keep moving.
When you're trolling spanish mackerel, you want to be moving at a clip—usually between 5 and 7 knots. Sometimes, if the water is really warm and the fish are dialed in, you can even push it to 8. You want that lure to look like a frantic baitfish trying to escape for its life. If you think you're going too fast, you're probably just getting to the right speed. A good rule of thumb is to watch your lures; they should be dancing and vibrating with a lot of energy.
The classic planer and spoon setup
You really can't talk about these fish without mentioning the Clarkspoon. It's been the gold standard for decades for a reason: it works. But because mackerel often sit a few feet below the surface, you need a way to get those spoons down to them.
This is where the planer comes in. A small #1 or #2 planer is usually all you need. It's a simple metal device that dives as you pull it through the water. When a fish hits the lure, the planer "trips," meaning it loses its resistance and pops up, allowing you to fight the fish without the heavy drag of the metal plate.
If you aren't a fan of planers, you can use cigar weights or torpedo weights, but planers are generally more consistent at staying at a specific depth. Just remember to use a long leader—at least 15 to 20 feet of 20-30lb monofilament or fluorocarbon behind the planer. Mackerel have incredible eyesight, and if they see a big hunk of metal right in front of the shiny spoon, they might shy away.
Finding the "washing machine"
You can have the best gear in the world, but it won't matter if you're trolling in a desert. Finding the fish is half the battle. The easiest way to spot them is to look for "the washing machine." This is what happens when a school of mackerel pushes baitfish to the surface and starts a feeding frenzy. The water literally looks like it's boiling.
Keep your eyes peeled for birds, too. Gulls and terns aren't hovering over empty water for the exercise; they're waiting for the mackerel to chop up baitfish so they can grab the leftovers. If you see birds diving, steer your boat toward the edges of that activity. Pro tip: don't drive your boat right through the middle of the school. You'll spook the fish and they'll dive deep. Instead, troll around the perimeter of the frenzy and let your lures pass through the "kill zone."
Why wire leaders are a toss-up
This is a constant debate among fishermen. Spanish mackerel have teeth like tiny razor blades. If you use standard mono, they can snip through it in a heartbeat. Because of this, many people reach for thin steel wire. It's "mackerel-proof," sure, but it's also very visible.
On bright, sunny days when the water is crystal clear, that wire can actually scare the fish off. I've had days where the guys using wire didn't get a single bite, while the guys using 30lb fluorocarbon were catching fish on every pass. Yes, you'll lose a few lures to "tooth-offs," but you'll likely get way more strikes. If the bite is slow, ditch the wire and switch to a heavy fluoro leader. It's a bit of a gamble, but usually, it's one that pays off with a full cooler.
Vary your lure depths and colors
Don't just put two of the exact same things out and hope for the best. When I'm trolling spanish mackerel, I like to run a "spread." This might mean one line has a planer to get deep, while another has a 2-ounce trolling weight to stay mid-column, and maybe a third line is just a small diving plug or a spoon skipping right on the surface.
Fish can be picky about color, too. Silver is the classic choice because it looks like a silverside or a menhaden, but don't sleep on gold or even pink. On overcast days, gold spoons often outperform silver because they provide a different kind of flash in lower light. If you find that one specific depth or color is getting all the hits, then you can switch your other lines to match.
Handling the chaos on deck
Once you get a double or triple hookup (which happens a lot), things can get pretty chaotic. Spanish mackerel are notorious for flopping around like crazy the second they hit the deck. Since they have those sharp teeth and even sharper gill plates, you want to be careful.
A lot of guys use a "dehooker" tool so they never have to actually touch the fish. You just slide the tool down the line, grab the hook, and flip the fish right into the cooler. If you're keeping them for dinner—and you should, they're delicious—bleed them immediately. A quick cut to the gills and a soak in a slushy ice bath makes a world of difference in the flavor. Mackerel are oily fish, and if they aren't iced down right away, the meat can get soft and "fishy" pretty fast.
Don't ignore the structure
While you'll often find mackerel in open water chasing bait, they also love to hang out around structure. Nearshore reefs, wreck sites, and even the ends of long piers are prime real estate. These spots act as a buffet for mackerel because they attract the small fry they prey on.
If you're trolling near a reef, keep a close eye on your depth finder. You want to see "ledges" or bait balls holding near the bottom. Sometimes the mackerel will be suspended just above the structure. If you aren't getting hits in the open ocean, try making a few passes over a known wreck. Just be careful not to let your planers get too deep, or you'll end up hooking the reef instead of a fish, and that's a quick way to lose your expensive rigging.
The "don't stop" rule
One final thing to remember: when a fish hits, don't stop the boat. This isn't like bottom fishing where you want to stay over the spot. When you're trolling spanish mackerel, you want to keep the boat moving forward at a steady pace.
First off, it keeps the tension on the line, which is vital because mackerel have relatively soft mouths and can shake a hook easily if the line goes slack. Secondly, because they travel in schools, there's a high chance another fish is right behind the one you just hooked. By keeping the boat moving, you're keeping your other lures in the strike zone, often leading to those fun "every rod is bent" moments.
Trolling is really about patterns. Once you figure out the speed, the depth, and the color they want, you can just keep repeating that pattern until you've had your fill. It's a high-energy, fast-paced way to fish that's perfect for kids or anyone who doesn't have the patience to sit and stare at a bobber all day. Give it a shot next time you see the birds diving—you won't regret it.
