How to Clean and Fillet a Bass: Tools, Step-by-Step Cuts, Skinning and Storage

To fillet a bass, keep the fish cold, then use a sharp, flexible fillet knife: cut behind the gill plate down to the backbone, turn the blade and run it along the backbone to the tail, repeat on the other side, cut away the rib cage and slide the blade between the skin and meat. Rinse and pat the fillets dry, refrigerate them and cook within a day or two, or freeze them. Before you fillet anything, make sure the fish is legal to keep and that your state allows filleting before you get home.

Before you start

• Know the rules. Size and bag limits vary by state and water. Some states also require fish to stay whole, or fillets to keep a patch of skin, while you’re on the water or transporting them, so officers can identify the species and check sizes. Check your state wildlife agency’s regulations.
• Keep fish cold. Put fish you’re keeping in an aerated livewell or straight onto ice. Fish that sit in warm water or a hot cooler lose quality fast. Our guide can you eat bass? covers which fish are best to keep and how to check fish advisories.
• Plan for the leftovers. Use a fish cleaning station if there is one, or bag carcasses for the trash. Some places don’t allow dumping fish remains in the water or at the ramp.

Tools you need

• Fillet knife with a thin, flexible blade; about 6 to 7 inches suits most bass, and a slightly longer blade helps on big stripers. An electric fillet knife speeds up large batches.
• Knife sharpener. A dull knife wastes meat and is more dangerous because it slips.
• Cutting board, ideally a fillet board with a clamp to hold the fish.
• Cut-resistant glove for the hand holding the fish.
• Paper towels, a bowl of cold water, freezer bags or a vacuum sealer, and a trash bag.

How to fillet a bass, step by step

1. Prep the fish. Wipe off excess slime so it doesn’t slide. Lay it on its side on the board.
2. Make the first cut. Just behind the gill plate and pectoral fin, cut down at a slight angle toward the head until you feel the backbone. Don’t cut through it.
3. Run along the backbone. Turn the blade toward the tail so it lies flat against the backbone. With smooth, sawing strokes, cut toward the tail, keeping the blade tight to the bones. You can cut through the rib bones here and remove them later, or work the blade over the top of the rib cage.
4. Finish at the tail. Cut the fillet free at the tail, or stop just short and leave it attached by a strip of skin; flipping it over the tail makes skinning easier.
5. Repeat on the other side. Flip the fish and make the same cuts.
6. Remove the rib cage. If the ribs are still attached to the fillet, slide the knife tip under them and cut them away in a thin slice, taking as little meat as possible.
7. Skin the fillet. Place it skin side down. Grip the tail end of the skin (a pinch of salt or a paper towel helps), angle the blade slightly toward the skin, and push it forward with a gentle side-to-side motion while pulling the skin back.
8. Trim. Cut away the darker strip of meat along the lateral line for a milder flavor, along with any belly fat or remaining bones.
9. Rinse and dry. Rinse briefly in cold water and pat dry.

Run a fingertip along each fillet before packing it. Bass don’t have the Y-bones found in pike, so once the rib cage is gone, you’ll rarely find more than a stray small bone near the front of the fillet. The same method works for crappie, white bass and larger sunfish; see our crappie fishing tips for the fish themselves.

Cleaning a bass to cook whole

Pan-sized fish can be scaled and gutted instead of filleted:

1. Scrape off the scales with a scaler or the back of a spoon, working from tail to head.
2. Cut the belly open from the vent up to the gills.
3. Remove the guts and gills, and scrape out the dark blood line along the backbone.
4. Rinse inside and out with cold water, and remove the head if you prefer.

Storing bass fillets safely

Bass is a lean white fish, which helps it freeze well. Typical times from federal cold-storage charts:

Freezer times are about quality, not safety: fish kept continuously frozen at 0°F stays safe, but texture and flavor decline over time. Fatty fish such as catfish and salmon keep their best quality for a shorter time, about 2 to 3 months.

Thawing and cooking

Thaw frozen fillets overnight in the refrigerator. For a faster thaw, seal them in a plastic bag and submerge it in cold water. The FDA’s seafood safety guidance says most seafood should be cooked to an internal temperature of 145°F; the flesh should be opaque and flake with a fork.

Safety at the cleaning table

• Always cut away from your body and your holding hand.
• Keep the knife sharp and the board and your hands as dry as practical.
• Watch the dorsal spines and gill covers, which can puncture skin.
• Wash hands, knives and boards with hot soapy water afterward, and don’t let raw fish touch ready-to-eat food.

Bottom line

Filleting a bass takes a few minutes once you’ve done it a few times: a cut behind the gills, a pass along the backbone, rib removal and skinning. Keep the fish cold from the moment you decide to keep it, follow your state’s rules on limits and transporting fillets, refrigerate fillets for no more than a day or two, freeze the rest airtight, and cook to 145°F.

FAQ

Do you need to scale a bass before filleting?

No. If you skin the fillets, the scales come off with the skin. Scale the fish only if you plan to cook it whole or with the skin on.

How long can bass fillets stay in the fridge?

About 1 to 2 days at 40°F or colder. If you won’t cook them by then, freeze them.

What size fillet knife is best for bass?

A thin, flexible blade of about 6 to 7 inches handles most bass. Bigger fish like stripers are easier with a slightly longer blade.

Should I remove the dark meat from bass fillets?

It’s optional, but trimming the darker strip along the lateral line gives a milder taste, especially with white bass and stripers.
