A typical salmon fillet contains about 29 pin bones, and every one of them can be removed in under five minutes with the right tool and a simple technique. These thin, flexible bones run in a line through the thickest part of the fillet, and pulling them out cleanly comes down to three things: keeping the fish cold, using a tool with a good grip, and pulling at the correct angle.
Where Pin Bones Are and How to Find Them
Pin bones aren’t part of the spine. They develop in the connective tissue between muscle segments on each side of the fish, extending from near the backbone out into the flesh. In a salmon fillet, they form a single row that runs from the head end (the thicker collar area) roughly two-thirds of the way toward the tail. You won’t find them in the thin tail section.
The easiest way to locate them is to run your fingertip along the center of the fillet, pressing gently. You’ll feel the sharp tips poking up slightly from the surface. If you have trouble detecting them, flip the fillet skin-side down and drape it over an inverted bowl or a rolled-up kitchen towel. The curve pushes the flesh outward and forces the bone tips to protrude, making them much easier to see and grab.
Keep the Fillet Cold
Salmon flesh is soft because it’s loaded with intramuscular fat. At room temperature, that fat is pliable, and the flesh tears easily when you tug on a bone. Chilled fat is firmer, the same reason cold bacon is easier to slice into clean strips. Work with your fillet straight from the refrigerator, and if you’re deboning a large side of salmon, put it back in the fridge partway through rather than letting it warm up on the counter.
Choosing the Right Tool
You have two practical options at home: fish tweezers or pliers-style bone pullers.
- Fish tweezers are flat, spring-loaded, and designed for precision. They work well for smaller fillets or when you’re only removing a handful of bones. Look for a pair with grooved or ridged tips, which grip the slippery bone without letting it slide free.
- Pliers-style tools (sometimes called fish bone pliers) offer more leverage and a stronger grip. They’re the better choice for salmon specifically, since salmon pin bones are relatively thick compared to those in smaller fish like mackerel or snapper. Needle-nose pliers from a hardware store technically work, but dedicated fish bone pliers have wider, textured jaw surfaces that hold the bone more securely and are less likely to snap it.
Whichever tool you choose, the grooved or textured tip matters more than the overall design. A smooth grip is the main reason bones break mid-pull.
The Removal Technique
Place the fillet skin-side down on a cutting board or draped over a bowl. Start at the collar end, the thicker side of the fillet where the head was. The bones are largest and easiest to grip here, so beginning at this end lets you build a rhythm before reaching the smaller, trickier bones closer to the center.
Grip the tip of the first protruding bone with your pliers or tweezers and pull at a 45-degree angle, directing your pull slightly toward the belly side of the fillet. This angle matters. Pulling straight up tears through the muscle fibers and leaves a ragged channel in the flesh. Pulling at 45 degrees toward the belly follows the natural orientation of the bone, so it slides out with minimal damage.
As you pull, use the thumb and forefinger of your free hand to press down gently on the flesh surrounding the bone. This counter-pressure keeps the fillet from lifting off the board and prevents the flesh from tearing around the exit point. Work your way down the row one bone at a time, wiping your pliers on a damp towel periodically so the grip stays clean.
What to Do When a Bone Breaks
If a bone snaps below the surface, don’t panic. Press your fingertip firmly along the area where it broke to relocate the remaining stub. You can often coax the broken end back above the surface by pressing the flesh around it from underneath, especially if the fillet is draped over a curved surface. Grab the exposed tip with your pliers and pull at the same 45-degree angle. If the stub is too short to grip, a pair of fine-tipped tweezers with a sharp edge can reach slightly below the surface to catch it.
The most common reason bones break is pulling at the wrong angle or using a tool with smooth, slippery jaws. Keeping the fish cold also reduces breakage, because firmer flesh holds the bone in place and provides resistance that keeps the bone from flexing and snapping.
Checking Your Work
After you’ve pulled what feels like the full row, run your fingertip along the entire length of the fillet one more time. Pay extra attention to the transition zone where the rib cage ends and the pin bone row begins, since a bone or two often hides there. Some cooks hold the fillet up to a light source, which can reveal shadows cast by any remaining bones just beneath the surface.
With 29 bones to remove, it’s easy to lose count. A final finger check takes ten seconds and saves someone at the dinner table from an unpleasant surprise.
Buying Salmon With Bones Already Removed
Most skin-on salmon fillets at supermarkets are sold with pin bones still intact, though some fishmongers remove them on request. Center-cut portions and pre-portioned salmon steaks are more likely to have been deboned. If the label says “boneless,” the pin bones have already been pulled, but it’s still worth a quick check with your fingertip before cooking. Commercial processors use automated machines or handheld electric pullers that grip and extract bones rapidly, but even these systems occasionally miss one.
