How to Catch Salmon: Freshwater vs Saltwater Techniques – From a Guy Who’s Chased Them for 25 Years

Hey guys, Tom here. Lately, I’ve been getting flooded with the same question, and I get it—salmon are the holy grail for a lot of anglers. Everyone wants to land that silver (or red, or king) beauty, but the biggest mistake I see new guys make is treating freshwater salmon fishing the same as saltwater. Let me set the record straight right now: they’re two totally different games. You can’t use the same gear, the same lures, or the same mindset and expect to catch fish in both. Trust me—I learned that the hard way.

Over 25 years, I’ve chased salmon from the icy freshwater rivers of Alaska to the choppy saltwater bays of Washington. I’ve caught 40lb king salmon (chinook) in the open ocean and 15lb sockeye in a shallow, rushing river. I’ve also spent entire days skunked because I used a saltwater lure in freshwater, or ignored the current in a river like it didn’t matter. Today, I’m breaking down everything you need to know—no fluff, no fancy jargon, just the real techniques, gear, and personal horror stories that’ll help you land more salmon, whether you’re standing in a river or sitting in a boat offshore. Let’s dive in.

First, Let’s Get One Thing Straight: Not All Salmon Are the Same (And Neither Are the Waters)

Before we talk techniques, you need to understand the difference between salmon in freshwater vs. saltwater—and it’s not just the water’s salt content. Salmon are anadromous, which means they’re born in freshwater, migrate to saltwater to grow, then swim back to freshwater to spawn. That means the salmon you catch in a river (freshwater) are either spawning or on their way to spawn, while the ones you catch in the ocean (saltwater) are feeding and growing. Their behavior, their appetite, and even their appearance are different—and that changes everything about how you fish for them.

I once made the mistake of assuming a salmon is a salmon, no matter where you catch it. I took my saltwater trolling gear to a freshwater river in Alaska, cast a big, flashy lure, and spent 8 hours not even getting a nibble. A local guide saw me struggling, walked over, and said, “Son, you’re fishing for a fish that’s here to spawn, not eat. That lure’s too big, and you’re dragging it too fast.” He handed me a small fly, showed me how to drift it with the current, and 10 minutes later, I caught my first freshwater sockeye. Lesson learned: context is everything.

Quick breakdown (the CliffsNotes version, so you don’t look like a rookie):

Freshwater Salmon: Mostly sockeye (red salmon), coho (silver salmon), and chinook (king salmon) on their spawning run. They’re less interested in feeding (they stop eating once they enter freshwater, for the most part) and more likely to strike out of aggression or curiosity. Waters are colder, shallower, and faster-moving (rivers, streams, some lakes). The season typically runs from late spring to fall, with peaks depending on the species—king salmon start their freshwater run in mid-May, followed by sockeye in June through August, and coho in August through October.
Saltwater Salmon: Chinook, coho, and pink salmon (humpies) feeding in bays, inlets, and offshore waters. They’re hungry, actively chasing baitfish, and will strike harder. Waters are deeper, saltier, and have tides and currents that affect where the fish are. The best saltwater fishing for coho is mid-August through September, while king salmon are most abundant offshore from late April through June, with immature “feeder” kings present year-round (best fishing May to July).

Freshwater Salmon Fishing: Techniques That Actually Work (From Someone Who Wasted Years Doing It Wrong)

Freshwater salmon fishing is all about patience, precision, and reading the water. These fish aren’t here to eat—they’re here to spawn—so you’re not “tricking” them with bait; you’re triggering a reaction. I’ve spent more days than I care to admit standing in a freezing river, casting the wrong lure, and wondering why I wasn’t catching anything. Here’s what actually works, based on 25 years of trial and error:

1. The #1 Technique: Drift Fishing (My Go-To for Rivers)

Drift fishing is the most effective way to catch freshwater salmon, hands down. It’s simple: you cast your bait or lure upstream, let it drift naturally with the current, and keep your line tight so you can feel even the smallest strike. The key is to match the speed of your bait to the current—if it’s moving too fast or too slow, the salmon won’t notice it.

My mistake early on: I was casting downstream and reeling in too fast, which made my lure look unnatural. A local angler watched me for 10 minutes, then yelled, “Let the river do the work!” He was right. Here’s how to do it right:

Gear: Use a 7’6” to 8’ medium-heavy spinning rod (stiff enough to handle big salmon, flexible enough to feel strikes) with 12-15lb monofilament line. Add a 24-36 inch fluorocarbon leader (6-8lb test)—salmon in clear freshwater have sharp eyes, and fluorocarbon is nearly invisible underwater. For weights, use split shot sinkers (size 3/0 to 7) to keep your bait near the bottom, where salmon hang out. I prefer a sliding sinker setup so the salmon doesn’t feel the weight when it strikes—trust me, they’re skittish.
Bait/Lures: Since freshwater salmon don’t eat much, you want something that looks like a small fish or insect, or something that triggers aggression. My go-tos:
- Spawn Sacks: These are little bags of salmon roe (eggs)—salmon hate seeing other salmon’s eggs in their spawning territory, so they’ll strike to move them. I buy pre-made spawn sacks (salmon or trout roe) from the tackle shop, but you can make your own if you’re feeling ambitious. I once caught 5 sockeye in an hour using nothing but spawn sacks drifted near a gravel bar.
- Flies: Fly fishing is a classic for freshwater salmon, and for good reason. Use small, bright flies (red, orange, pink) that mimic insects or small baitfish. I use a size 6-8 egg fly or a small streamer—cast upstream, let it drift, and give it a tiny twitch every few seconds to make it look alive. Early morning and late evening are the best times to fly fish for freshwater salmon, as lower light makes them more active.
- Jigs: Small jigs (1/8 to 1/4oz) in bright colors (chartreuse, pink) work great too. Cast upstream, let it sink to the bottom, then reel in slowly, giving it a slight bounce every few inches. This mimics a small fish struggling in the current—salmon can’t resist it.
Where to Fish: Look for “holding spots” in the river—places where salmon rest before continuing their spawning run. These are usually deep pools, behind rocks, or along the edges of the current (called “seams”). I once spent an hour fishing a shallow, fast part of the river with no luck, then moved to a deep pool behind a large boulder and caught 3 coho in 20 minutes. Salmon don’t like fighting the current nonstop—they need places to rest.

2. Fly Fishing: For the Purists (And the Patient)

Fly fishing for freshwater salmon is an art, and it took me years to master. It’s not about casting far—it’s about casting accurately and matching the hatch (or in this case, the salmon’s mood). I use a 9’ medium-heavy fly rod with a floating line for shallow rivers, or a sinking line for deeper pools. The key is to present the fly naturally—no sudden movements, no jerky reels. Salmon in freshwater are skittish, and any unnatural movement will scare them off.

Pro Tip (from a guy who’s hooked more trees than salmon): Practice your cast on land before hitting the river. I once spent 30 minutes untangling my fly from a tree while a school of sockeye swam past me. Embarrassing? Yes. A lesson? Absolutely. Also, use a leader that’s the same length as your rod—this gives you more control over the fly and makes it drift more naturally.

3. Freshwater Mistakes to Avoid (I Made All of Them)

Using Saltwater Gear: Don’t do it. Saltwater rods are too stiff, saltwater lures are too big, and saltwater line is too visible. I once tried to use my saltwater trolling rod in a river—cast once, and the line got tangled in the current. Total waste of time.
Fishing Too Fast: Salmon in freshwater are slow-moving—they’re not chasing bait, they’re resting. If you reel in too fast, your bait will look unnatural. Take your time, let the current do the work, and be patient.
Ignoring the Weather: Cold, overcast days are best for freshwater salmon fishing. If it’s sunny and hot, the fish will move to deeper water and become less active. I once fished a river on a 90-degree day in July—caught nothing. Came back the next day, which was cloudy and 65 degrees, and caught 4 sockeye. Lesson: check the forecast.

Saltwater Salmon Fishing: Techniques for Chasing Hungry Fish (And Avoiding Sea Sickness)

Saltwater salmon fishing is a whole different ballgame. These fish are hungry, fast, and they’re constantly on the move. Unlike freshwater salmon, they’re actively feeding, so you can use bigger lures, faster retrieves, and cover more water. I’ve fished saltwater salmon from small boats, large charters, and even piers—and while the gear and techniques vary, the core principle is the same: find the baitfish, and you’ll find the salmon.

My first saltwater salmon trip was a disaster. I went out with a buddy in his 16-foot boat, forgot my sea sickness pills, and spent half the day throwing up over the side. When I finally got my act together, I cast a freshwater fly (stupid mistake) and got nothing. My buddy handed me a big, flashy spoon lure, told me to troll it behind the boat, and 10 minutes later, I hooked a 25lb coho. I was hooked (pun intended)—and I learned that saltwater salmon fishing is all about covering water and matching the bait.

1. The #1 Technique: Trolling (Cover More Water, Catch More Fish)

Trolling is the most effective saltwater salmon technique—period. It lets you cover large areas of water, which is crucial because saltwater salmon are constantly moving to find baitfish. The idea is to drag lures behind your boat at a slow speed (2-3 mph) and mimic the movement of a school of baitfish. I’ve caught more salmon trolling than any other technique—including a 40lb king salmon off the coast of Washington that took me 20 minutes to reel in.

Gear: Use a 7’ to 8’ medium-heavy casting rod (baitcaster or spinning) with 20-30lb monofilament or braided line. Braided line is better for trolling because it’s stronger, more sensitive, and has less stretch—you’ll feel even the smallest strike. Add a 36-inch fluorocarbon leader (15-20lb test) to keep the line invisible to salmon. For trolling, you’ll also need downriggers or weights to get your lure to the right depth—salmon in saltwater are often 20-60 feet below the surface, especially in summer. I use a fish finder to see where the fish are—trust me, it’s like cheating (but in a good way).
Lures/Bait: Saltwater salmon love big, flashy lures that mimic baitfish like herring, anchovies, or smelt. My go-tos:
- Spoons: Large, metallic spoons (3-4 inches) in silver, gold, or chartreuse. They reflect light and create a lot of movement in the water—salmon can see them from far away. I once caught 3 coho in a row using a silver spoon trolled near a school of herring.
- Plug Lures: These are hard-bodied lures that look like small fish. They dive when you troll them, which is perfect for getting to the right depth. I prefer plug lures with a tight wiggle—they mimic a wounded baitfish, which salmon can’t resist. The most effective technique for catching king salmon in saltwater is trolling a fresh or frozen herring, which works even better than artificial lures if you can get your hands on it.
- Live Bait: If you can get live herring or anchovies, use them. Hook a live herring through the lips (so it stays alive longer) and troll it slowly—salmon will strike it hard. I once used live herring on a charter trip and caught 5 salmon in 2 hours. Worth the extra effort.
Where to Fish: Look for areas with baitfish—you’ll see seagulls diving (they’re feeding on the same baitfish as salmon) or ripples on the water (sign of a school of baitfish). Salmon also hang out near structure: kelp beds, rock piles, and drop-offs. I once trolled near a kelp bed and caught 4 coho in 30 minutes—they were hiding there, waiting for baitfish to swim by. Nearshore areas off points of land, where tidal currents create ambush points for baitfish, are also prime spots for king salmon.

2. Casting from Piers/Shore (Yes, You Can Catch Saltwater Salmon from Land)

You don’t need a boat to catch saltwater salmon—piers and rocky shorelines work great, especially during high tide. I’ve caught coho and pink salmon from piers in Washington, and it’s just as exciting as fishing from a boat. The key is to cast into deep water, near baitfish schools, and use a fast retrieve.

Gear: Use a 8’ to 9’ medium-heavy spinning rod with 20-30lb braided line (for distance) and a 30-inch fluorocarbon leader. Use the same lures as trolling (spoons, plug lures) but smaller (2-3 inches). Cast as far as you can, let the lure sink for 5-10 seconds, then reel in fast—saltwater salmon strike quickly, so you need to be ready.

Pro Tip: Fish during high tide. Salmon move closer to shore during high tide to feed on baitfish that get pushed in by the water. I once fished a pier during low tide—caught nothing. Came back during high tide, and caught 2 coho in 15 minutes. Timing is everything.

3. Saltwater Mistakes to Avoid (Again, I Made All of Them)

Trolling Too Fast: Salmon in saltwater are fast, but if you troll too fast, your lure will look unnatural. Stick to 2-3 mph—any faster, and you’ll miss strikes. I once trolled at 5 mph (trying to cover more water) and got nothing. Slowed down to 2 mph, and caught a coho 10 minutes later.
Using Too Light Gear: Saltwater salmon are bigger and stronger than freshwater salmon—you need heavy gear to handle them. I once used a freshwater rod to fish for saltwater coho, and the rod snapped when I hooked a big one. Total disaster. Invest in a good saltwater rod—you’ll thank me later.
Forgetting Sea Sickness Pills: Trust me, you don’t want to spend your day throwing up over the side. I learned this the hard way on my first saltwater trip. Even if you don’t think you get sea sick, bring the pills—better safe than sorry.

Gear Breakdown: Freshwater vs Saltwater (No More Wasting Money on the Wrong Stuff)

One of the biggest mistakes new anglers make is buying the wrong gear for the water they’re fishing. I’ve wasted hundreds of dollars on gear that worked in saltwater but was useless in freshwater (and vice versa). Here’s a quick breakdown of the gear you need for each—no fluff, just the essentials:

Freshwater Salmon Gear

Rod: 7’6” to 8’ medium-heavy spinning rod (flexible enough to feel strikes, stiff enough to handle big salmon)
Reel: Spinning reel (size 3000-4000) with a smooth drag system (salmon fight hard, so you need a good drag)
Line: 12-15lb monofilament main line, 6-8lb fluorocarbon leader (24-36 inches)
Tackle: Split shot sinkers (size 3/0 to 7), spawn sacks, small jigs (1/8-1/4oz), fly fishing flies (size 6-8)
Extras: Waders (for cold rivers), non-slip boots (rocky river bottoms are slippery), a net (to land the fish without losing it)

Saltwater Salmon Gear

Rod: 7’ to 8’ medium-heavy casting or spinning rod (stiffer than freshwater rods to handle big, fast salmon)
Reel: Baitcaster or spinning reel (size 4000-5000) with a strong drag system
Line: 20-30lb braided main line (for strength and sensitivity), 15-20lb fluorocarbon leader (36 inches)
Tackle: Large spoons (3-4 inches), plug lures, live herring/anchovies, downriggers or weights (for trolling)
Extras: Sea sickness pills, sunscreen (saltwater sun is brutal), a landing net (big enough for 40lb salmon), pliers (to remove hooks)

My Personal Verdict: Freshwater vs Saltwater Salmon Fishing

Guys, I love both. Freshwater salmon fishing is peaceful—standing in a cold river, listening to the water rush by, and waiting for that subtle strike. It’s about patience and precision, and there’s nothing like landing a sockeye in the same river it was born in. Saltwater salmon fishing, on the other hand, is adrenaline-fueled—trolling fast, feeling a big salmon hit, and fighting it for 20 minutes while it pulls your boat around. It’s about covering water and chasing the action.

If you’re a beginner, start with freshwater salmon fishing. It’s more accessible (you don’t need a boat), and it teaches you the basics of reading water and feeling strikes. Once you master freshwater, move to saltwater—you’ll be ready for the bigger, faster fish. I started with freshwater sockeye, then moved to saltwater coho, and now I split my time between both.

My biggest piece of advice: Spend time on the water. You can read all the articles in the world, but nothing beats hands-on experience. I’ve had days where I caught nothing, and days where I couldn’t keep up. The more you fish, the better you’ll get at reading the water, choosing the right lure, and landing the big one.

Final Pro Tips (From a Guy Who’s Been There, Done That)

For Freshwater: Fish early morning or late evening—salmon are more active when the sun is low. Focus on deep pools and seams in the current. And always use a net—salmon are slippery, and you don’t want to lose a big one right at the shore. Also, pay attention to the run timing: king salmon in freshwater start mid-May, sockeye in June-August, and coho in August-October.
For Saltwater: Use a fish finder to find baitfish—where there’s bait, there’s salmon. Troll at 2-3 mph, and adjust your depth until you find the fish. If you’re fishing from a pier, cast during high tide and reel in fast. And don’t forget to rinse your gear with fresh water after each trip—saltwater corrodes gear fast. For saltwater king salmon, target nearshore areas off points of land or around kelp beds, and use fresh/frozen herring for the best results.
No Matter Which You Choose: Patience is key. Salmon fishing isn’t easy—you’ll have bad days. But when you hook that big one, and you reel it in, all the frustration is worth it. I once spent 3 days fishing for freshwater sockeye with no luck, then caught a 18lb one on the fourth day. It’s moments like that that keep me coming back.

At the end of the day, salmon fishing is about more than catching fish—it’s about being on the water, enjoying the outdoors, and sharing the experience with friends. Whether you’re standing in a river or sitting in a boat, the feeling of hooking a salmon is like no other.

If you have questions, hit me up. I’m happy to take you out on the water—fresh or salt—and show you the ropes. No judgment, just good company and hopefully some big salmon. Tight lines, fellas.
