When it comes to salmon fishing on Lake Michigan, most anglers are familiar with the essentials: find the right depth, use the right lure, match the speed, and follow the seasonal migration. But there’s one often-overlooked tactic that can turn a good day on the water into a great one—using scent to attract more salmon.
If you’ve booked a charter fishing trip out of the port of Saugatuck, you’re in prime territory for king and coho salmon, especially during the late spring through early fall. While trolling is the most productive technique we use on Lake Michigan, many of our guests are surprised to learn that scent—just like color, speed, and flash—can significantly increase our odds of hooking more fish.
Let’s break down why scent works, which salmon attractants are most popular and effective, and how we incorporate scent into trolling techniques without overdoing it or spooking the fish.
Why Scent Works for Salmon
Salmon are visual hunters, but they also have a highly developed sense of smell. Before returning to their natal rivers to spawn, salmon spend years in the open waters of Lake Michigan feeding on alewives and other baitfish. During that time, they rely not just on sight, but also on olfactory cues to locate food—and later, to home in on specific spawning grounds.
Scientific studies have shown that salmon can detect chemical compounds in parts per billion, making their sense of smell thousands of times more sensitive than humans. That means even a small amount of scent in the water can act like a homing beacon to nearby fish.
Here’s how it works while trolling:
- As your boat moves through the water dragging lures and flies, scent disperses in a trailing cloud, similar to the way flashers throw off light.
- This scent trail mimics feeding activity, triggering nearby salmon to investigate.
- If the scent matches something familiar or appealing—like herring oil or shrimp extract—the fish is far more likely to strike.
In short, scent adds one more layer of attraction to your spread. And when salmon are being picky (which happens often!), this extra sensory input can make the difference between a follow and a strike.
Popular Salmon Attractants: What Works on Lake Michigan
There are a number of commercial and homemade salmon attractants that have stood the test of time on the Great Lakes. These fall into two broad categories:
- Natural scents (derived from baitfish, crustaceans, or amino acids)
- Enhanced scents (infused with oils, garlic, or pheromones)
Here are the most commonly used and effective attractants for trolling salmon out of Saugatuck:
Herring Oil
Herring is a primary food source for salmon in saltwater, and while Lake Michigan salmon don’t typically eat herring, they instinctively react to its smell. Herring oil is a potent and proven attractant, often added to trolling flies or meat rigs.
We use herring oil often on our charters, especially early in the season when salmon are aggressively feeding and more prone to chase scent.
Shrimp and Krill Extract
Coho salmon in particular are known to favor shrimp and krill. These scents work very well in the spring when cohos are closer to shore. Shrimp oil is especially effective when applied to orange or pink spoons and dodgers that already mimic shrimp in appearance.
Garlic
Yes, garlic! It’s one of the surprise ingredients that works wonders in freshwater. Some theories suggest garlic masks unnatural odors (like human scent, gasoline, or plastic), while others believe it’s simply attractive to fish due to its strong profile. Either way, garlic-scented gels or oils are part of our standard trolling toolkit.
Anise
Anise oil, which smells like black licorice, is another unexpected but effective scent. Some believe it acts as a stimulant, while others say it neutralizes repellent smells. Either way, many anglers swear by anise oil for both trout and salmon, and we’ve had solid success using it on slower days.
Menhaden and Sardine Oil
These are more saltwater-based oils, but salmon recognize them from their Pacific ancestors. While not as commonly used as herring or shrimp, they can be a good wildcard when the usual attractants aren’t working.
Amino Acid Blends
Some commercial attractants use amino acids—the building blocks of protein—to stimulate feeding behavior. Products like Pro-Cure’s “Super Gel” and Atlas Mike’s line of scent attractants contain blends that target salmon specifically. These are often stickier and last longer than simple oil-based formulas.
How We Apply Scent While Trolling
Adding scent to your trolling spread is not about drenching everything in fish oil—it’s about subtle, strategic application that enhances your presentation without overwhelming the fish or making a mess.
Here’s how we do it on board during our Saugatuck charters:
Scenting Trolling Flies
Trolling flies are commonly used behind dodgers or flashers to target kings and cohos. These flies are often made of synthetic material like mylar or tinsel, which won’t absorb oil on their own. But you can apply scent in a few effective ways:
- Cotton Insert: We sometimes tuck a small cotton ball or piece of sponge inside the fly’s head. This holds scent much longer than applying it to the exterior.
- Gel-Based Attractants: Thicker gels like Pro-Cure “Super Gel” can be lightly smeared along the skirt or hook shaft. These stick better and don’t wash off as quickly at trolling speeds.
- Scent Chamber Heads: Some flies now come with small scent reservoirs built into the head, designed to slowly release attractant while trolling.
Scenting Spoons
Spoons are traditionally used without scent, but they can benefit from it under the right conditions—especially during tough bites or post-front conditions when fish are finicky.
To scent a spoon:
- Use scents in gel or paste form, which adhere to the spoon’s concave back.
- Apply a light smear—just enough to leave a trail, but not so much that it disrupts the lure’s action.
- Avoid heavily scented colors (like glow green with garlic) in clear water, as it may spook fish. Match the scent to the forage and the color to the conditions.
Meat Rigs and Cut Bait
If we’re running meat rigs (especially later in the summer when kings are staging), scent becomes an even bigger part of the program. The natural scent of the bait itself is already strong, but we often:
- Brine the bait in herring oil or garlic the night before.
- Use injectable scent in the baithead to slowly leak attractant over time.
- Pair with scent-matched flashers (e.g., green/glow with herring oil).
This combo is deadly when kings are holding deeper and reacting to scent trails rather than visual cues.
Don’t Spook the Fish: Avoiding Scent Mistakes
While adding scent is generally a positive strategy, it’s also easy to overdo it. Too much scent or the wrong kind can actually repel salmon rather than attract them.
Here are a few common scenting mistakes we help our guests avoid on board:
Mistake #1: Over-applying scent
A common mistake is to go heavy-handed with oil, thinking more scent equals more strikes. But too much scent can leave unnatural oil slicks in the water, which may alert wary fish that something’s off. We always apply scent sparingly—just enough to create a trail, not a puddle.
Mistake #2: Mixing incompatible scents
Don’t mix garlic with shrimp with herring with anise. Fish can’t process a scent cocktail like humans can—it just smells wrong. Stick with one or two complementary scents per lure, and keep your scent game simple.
Mistake #3: Scenting gear too close to the prop wash
Scents work best when applied to gear that’s away from the turbulent water directly behind the boat. We avoid scenting planer board lines or high divers that run in the bubbles—because it disperses the scent too quickly and may make it ineffective.
Mistake #4: Not cleaning old lures
Used lures can retain old scent or even human odors. We regularly clean spoons and flashers with a scent-free soap or vinegar solution, especially before applying new attractants. This prevents unwanted residue from interfering with fresh scent application.
