Mooching for Salmon: The Bite Is a Rod Going Straight

The oldest sport method in Puget Sound and still the most enjoyable. Drift with the tide, roll a cut-plug herring, and learn to recognize a bite that looks exactly like nothing happening.

Almost every way of catching a salmon involves pulling something past it. Mooching does not. You put a dead herring in the water, let the tide carry the boat, and wait for a fish to find it.

It is the oldest sport method in Puget Sound, it is still the most enjoyable one, and it is nearly unknown outside a strip of coast running from Olympia to Southeast Alaska. If you have only ever trolled with a downrigger, this is a different sport played with the same fish.

What mooching is

You are drifting, not motoring. Wind and tide move the boat, and the boat moves the bait.

On the end of the line is a cut-plug herring: a whole herring with its head cut off at an angle, so that when it is dragged through the water it rolls. Above it, five to seven feet up the leader, sits a curved lead sinker, usually called a banana or crescent sinker, whose shape keeps it from spinning.

You free-spool the whole thing down toward the fish. Then you retrieve slowly, or lift and drop the rod, and the herring spirals up through the water column looking exactly like something wounded.

That is the entire method. No engine noise, no hardware, no cable. Just a bait turning over in a tide.

How to Mooch for Salmon in Puget Sound, Step by Step

The rod is the whole system

A mooching rod looks wrong to anyone who fishes anywhere else. Nine to ten and a half feet long, and soft. Not fast, not stiff, not modern. It bends through most of its length under a modest load.

That softness is not nostalgia and it is not a compromise. It is the mechanism.

A salmon takes a herring sideways, in its mouth, and swims off with it before turning it to swallow. If the rod is stiff, the fish feels resistance immediately and lets go. If the rod is soft, it loads gradually, the fish feels almost nothing, and it keeps the bait long enough to be hooked.

The second job is protecting a hook hold. A salmon's mouth is soft in places and a big chinook thrashing at the boat will tear out of a stiff rod. A parabolic rod absorbs all of that.

Traditionally these were fished with a single-action reel, essentially a large direct-drive spool with no gearing, which old-timers call a knuckle-buster for reasons that become obvious the first time a fish runs. Most people now use a level-wind with a good drag, which is easier and gives up a little of the character.

The bait, which is most of the skill

Everything depends on how the herring rolls, and getting a good roll is a genuine craft.

The head comes off at an angle. Two angled cuts, one from each side, meeting at the top, so the finished head is a slanted, wedge-shaped face. That asymmetric face is what makes the bait spin as water passes over it.

Hooks go in so that the bait keeps a slight curve rather than hanging dead straight. Too straight and it will not turn. Too banana-shaped and it spins so fast it twists your leader into a corkscrew.

Then you test it. Drop it beside the boat at the speed the drift is moving and watch. What you want is a tight, fast, consistent spin, like a drill bit. A bait that wobbles lazily, or tumbles end over end, or hangs and does nothing, needs recutting.

That check takes eight seconds and it is the difference between fishing and pretending to fish. Experienced moochers check every time the bait goes down, because a herring that has been down for twenty minutes softens, and a soft herring stops rolling.

How to Rig a Cut Plug Herring for Salmon Fishing

The bite is a drop

This is the part that makes mooching unlike anything else, and the reason people who try it once without being told go home fishless.

A salmon eats the herring while swimming upward. Which means the weight comes off your line. The rod, which was bent under the sinker, straightens. The line goes slack.

Your bite looks like nothing happening.

Sometimes there is a tap or two first, as the fish bumps the bait. Sometimes the rod just softens. Occasionally there is a proper pull. But the classic mooching bite is a rod that stops being bent, and the correct response to it is not what any instinct suggests.

Do not strike.

Reel, fast and steadily, until you feel the weight of the fish. Only then lift into it. Striking at slack line pulls the bait away from a fish that has not turned it yet, and it is the single most common way to lose a mooching bite.

There is a related discipline: when the rod softens, keep reeling even if you think you were wrong. A fish that has taken and turned will be there when you come tight. A fish that has not will simply have not cost you anything.

Motor mooching

The variant, and the reason many charter boats fish this way.

Instead of drifting passively, you put the boat in and out of gear. In gear, the bait rises and speeds up. Out of gear, it slows and drops back.

That rise-and-fall is a much more provocative presentation than a steady drift, and it lets you fish a specific depth band along a specific piece of structure rather than going wherever the tide takes you. It is also how you cover water on a slack tide when a drift is not happening at all.

It is not slow trolling, which is worth saying, because it looks similar from a distance. Trolling pulls the bait at a constant speed. Motor mooching deliberately changes speed, and the change is the point.

Where the tide comes into it

Mooching is a tidal technique in a way trolling is not, and understanding that is most of the difference between a good day and a blank one.

The drift is powered by tidal current, so a slack tide means no drift, and no drift means a bait that hangs vertically and does nothing. The productive windows are the moving parts of the cycle, and the strongest of them concentrate bait against points, reefs and rips where the current accelerates.

Which means the day is planned around a tide table rather than around the clock. Reading a tide table covers the mechanics of that, including the point that matters most here: slack water is a different event from high water, and in the narrow passages of Puget Sound the difference can be an hour or more.

The other half is knowing where the structure is, which is a chart problem. Reefs, humps, drop-offs and the bottom types that hold bait are all drawn on the chart, and reading a nautical chart is how you find a mooching drift before you burn fuel looking for one.

What you catch

Chinook salmon are the primary target, and in Puget Sound the resident winter fish are called blackmouth, which is a local name for immature chinook that stay in the sound rather than heading to sea. They hold near bottom over structure, and mooching a herring right down among them is the classic way to take one.

Coho salmon come higher in the water column and take a bait moving faster, which is why coho fishing often means moving the bait more actively.

Pink and chum salmon get caught incidentally. Lingcod and halibut turn up when the bait is near bottom, which is a pleasant surprise and occasionally a problem for your leader.

Mooching against trolling

Worth comparing directly, because most people arrive at mooching from a boat that already has downriggers on it.

Trolling covers water. You can work a mile of shoreline in an hour, present four or six baits at four depths, and find fish by process of elimination. That is a genuine advantage and it is why trolling with downriggers is what most charter fleets do.

Mooching covers a drift. You go where the tide takes you at the speed the tide chooses, with one bait per angler. On a day when fish are scattered, that is a disadvantage and there is no arguing it away.

What mooching gives back is contact and quiet. There is no engine, no cable humming, no ball forty feet under the boat. On pressured water and in shallow water, that matters, and there is a long-standing view among Puget Sound anglers that mooching takes fish on days when trolling does not, particularly for blackmouth holding tight to structure in clear winter water.

It is also more engaging in a way that is hard to quantify. Trolling is largely waiting for a rod to fire. Mooching is a bait you cut, a roll you check, a depth you chose, and a bite you have to interpret. Whether that counts as an advantage depends on why you go fishing.

The practical answer for a boat that can do both is to troll to find fish and then shut the engine off and mooch through them.

The depth question

Getting the bait to the fish is the same problem it is in every other method, and mooching solves it with time rather than hardware.

There is no counter and no cable. What you have is a sinker, the current, and how long you let line out. So the discipline is counting: free-spool for a set number of seconds, or count pulls of line off the reel, and note what you did when a fish takes.

Bottom is the other reference. In much of the Puget Sound blackmouth fishery the answer is simply to go down until the sinker touches, crank up a few turns to get clear, and fish there. That takes the guesswork out entirely, at the cost of losing gear on rocky ground.

Sinker weight is the adjustment. Too light and the current sweeps everything up and away from the bottom; too heavy and the bait hangs unnaturally and stops rolling. The right weight is the lightest one that reaches the depth you want in the current you have, which is a sentence that appears in flatlining and longlining as well, because it is the same principle everywhere.

The rules, which change more than the fishing does

This is the part to take seriously, because Pacific salmon fisheries are among the most tightly and most frequently regulated in the country.

The classic mooching rig is two hooks on one leader. Whether that is legal depends on where you are. Washington's own definitions state that "a hook may be single-point, double, or treble" and then say plainly, "See Freshwater or Marine Area gear rules for limitations." The state is telling you that the general definition is not the operative rule and that your specific marine area is.

So look up the rules for the exact marine area and the exact dates you intend to fish, and look them up close to the day. Salmon seasons in Puget Sound are set annually through a negotiated process and are then modified in-season by emergency rule, sometimes with very little notice. A season that was open last weekend may not be open this one.

Things that vary and that a mooching angler needs to check: how many hooks are permitted on a line, whether they must be barbless, whether they must be single-point, whether bait is allowed at all in that area at that time, what the daily limit is, which species must be released, and whether only hatchery fish with a clipped adipose fin may be retained.

Washington defines a barbless hook as "a hook from which all barbs have been deleted when manufactured, filed off, or pinched down," so pinching down a barbed hook with pliers is explicitly acceptable where barbless is required.

And tribal fisheries operate under treaty rights and their own regulations. A state rule is not the operative rule everywhere in these waters.

None of this is a reason not to go. It is a reason to spend ten minutes on the agency's own current rules for your area before you launch, every trip, rather than relying on what was true last year.

The gear

A mooching rod, nine to ten and a half feet, soft through the middle. This is not a preference, it is the mechanism, and substituting a stiff rod changes the technique into something that does not work.

A level-wind reel with a smooth drag and enough capacity, or a single-action mooching reel if you want the traditional experience and do not mind the education.

Crescent or banana sinkers in a range from an ounce or two up to six or eight, because depth and current decide the weight and both change through a tide.

Good frozen herring, handled carefully. Bait quality matters more here than in almost any other fishery, because a soft or torn herring will not roll.

A sharp knife and a cutting board, plus the willingness to recut a bait that is not spinning properly.

Leader material and pre-tied rigs, made up to whatever hook configuration is legal where you are fishing that day.

Polarized glasses, a landing net with a deep bag, and a way to keep bait cold and firm all day.

The case for it

Mooching covers less water than trolling. It requires more attention, it demands a bait that rolls, and the bite is easy to miss.

What you get in exchange is a fish that ate because it wanted to rather than because something was dragged past it, on a rod that shows you every part of it, in a quiet boat with the engine off, usually at dawn on flat water.

It is also a small-boat method. No downriggers to mount, no cable, no ball, no spread to manage. A person in a fourteen-foot aluminum boat with a rod and a bag of herring is fishing the same way and about as effectively as the charter next to them, which is not true of most modern salmon fishing.

That combination, low equipment and high engagement, is why it has survived a century of gear that theoretically replaced it.

The short version

Drift with the tide, not the motor. Cut the herring's head off at an angle so it rolls, and check the roll beside the boat every single time it goes down. Long soft rod, five to seven feet of leader below a crescent sinker.

The bite is the rod going straight and the line going slack, because the fish took the bait and swam up. Do not strike. Reel until you feel weight, then lift.

Plan the day around a tide table and the drift around a chart.

And check the current rules for your specific marine area before every trip, because the hook rules, the seasons and what you may keep all change, sometimes mid-season.

Recommended gear

  • A mooching rod, nine to ten and a half feet

    Soft through the middle, not fast. This is the mechanism rather than a preference: a stiff rod lets the fish feel resistance and drop the bait before it has turned it.

  • A level-wind reel with a smooth drag

    Or a traditional single-action mooching reel if you want the full experience and do not mind what old-timers call a knuckle-buster the first time a chinook runs.

  • Crescent or banana sinkers in several weights

    From an ounce or two up to six or eight. The curved shape stops the sinker spinning, and depth and current decide the weight, both of which change through a tide.

  • Good frozen herring, kept cold and firm

    Bait quality matters more here than in almost any other fishery, because a soft or torn herring will not roll and a bait that does not roll does not catch.

  • A sharp knife and a cutting board

    Plus the willingness to recut a bait that is not spinning properly rather than fishing it anyway and hoping.

  • Pre-tied leaders in the legal configuration

    Made up to whatever hook count and hook type is permitted in the marine area you are fishing on the day you are fishing it.

  • A deep landing net and polarized glasses

    The net because a chinook at the boat on a soft rod takes some managing, and the glasses because you will spend the day watching a bait roll beside the hull.

Frequently asked

What is mooching?

Drifting with the tide while a cut-plug herring rolls through the water column below the boat, rather than pulling a lure past fish under power. The bait is fished five to seven feet below a curved sinker on a long soft rod, and the boat is moved by wind and current rather than the engine.

Why does a mooching rod have to be so soft?

Because a salmon takes a herring sideways and swims off with it before turning it to swallow. A stiff rod gives it resistance immediately and it lets go. A soft rod loads gradually so the fish feels almost nothing, and it also protects a hook hold in a soft mouth when a big fish thrashes at the boat.

What is a cut-plug herring?

A whole herring with the head removed by two angled cuts meeting at the top, leaving a slanted wedge-shaped face. That asymmetric face makes the bait spin as water passes over it, which is what makes it look like a wounded baitfish.

How do I know if my bait is rolling correctly?

Drop it beside the boat at drift speed and watch. You want a tight, fast, consistent spin like a drill bit. A lazy wobble, an end-over-end tumble or a bait that just hangs all need recutting. Check every time it goes down, because herring softens and a soft herring stops rolling.

What does a mooching bite feel like?

Usually like nothing. The salmon eats the herring while swimming upward, so the weight comes off your line, the rod straightens and the line goes slack. Sometimes there is a tap first. The classic bite is a rod that simply stops being bent.

What should I do when I get a bite?

Do not strike. Reel fast and steadily until you feel the weight of the fish, then lift into it. Striking at slack line pulls the bait away from a fish that has not turned it yet, and it is the most common way to lose a mooching bite.

What is motor mooching?

Putting the boat in and out of gear rather than drifting passively, so the bait rises and speeds up, then slows and drops back. That change of speed is the point, which is what makes it different from slow trolling, and it lets you work a specific depth along specific structure.

Is a two-hook mooching rig legal?

It depends entirely on where and when you fish, and you have to check. Washington's definitions say a hook may be single-point, double or treble and then explicitly direct you to the marine area gear rules for limitations. Hook counts, barbless requirements, bait restrictions, seasons and which fish may be kept all vary by area and change in-season by emergency rule.
