Bringing home fresh fish is one of the great rewards of a successful day on the water. The final step is turning the catch into clean, boneless fillets ready for the frying pan, barbecue, or freezer.

Fish vary considerably in shape and size, but the basic filleting process works for almost every species. Whether you are cleaning walleye, perch, trout, whitefish, or pike, the goal is the same. Follow the skeleton closely, leave as little meat behind as possible, and keep the fillet clean and cold.

Start with the Right Equipment

A sharp fillet knife is the most important tool. A flexible blade between six and nine inches long works for most freshwater fish. Smaller fish are easier to clean with a short-bladed knife, while a longer knife is better for large walleye, trout, or pike.

The knife should be sharp enough to slice without requiring excessive pressure. A dull knife is more likely to slip, tear meat, and cause an injury. Keep a sharpener nearby and touch up the blade whenever it starts dragging.

You will also need a stable cutting board, clean water, paper towels, and a container or sealable bag for the finished fillets. A fish-cleaning glove can provide extra grip and some protection for the hand holding the fish. Electric fillet knives are fast and efficient when cleaning large numbers of fish, but a traditional knife provides excellent control and is often the best choice for learning.

Make the First Cut

Place the fish on its side with its back facing you and its head toward your non-dominant hand. Hold the head firmly and position the knife immediately behind the gill plate and pectoral fin.

Angle the blade slightly toward the head to cut the meat around the collar. Cut down until the knife contacts the backbone, but not through it. Repeat on the other side, then join the two cuts at the top of the back, behind the head.

Follow the Backbone

Turn the knife so the cutting edge faces the tail. Insert the tip along the top of the backbone and begin slicing toward the tail.

Use long, smooth strokes rather than forcing the blade. Let the backbone guide the knife. The blade should remain almost flat and slide along the backbone, cutting through the ribs.

Keep the blade pointed slightly toward the bones. Angling it into the meat wastes flesh, while angling it too sharply toward the skeleton can cut through the backbone.

Stop just before cutting through the skin at the tail. Leaving the fillet attached by a small section of skin creates a convenient hinge, making skinning easier.

Work Over the Rib Cage

The rib cage curves away from the backbone and protects the internal organs. Place the fillet skin-side down, slide the knife under the rib bones, and follow their curve to remove them in a thin strip. Create a shallow cut on the top of the ribs to use as a guide with longer strokes of the blade.

Remove the Skin

Lay the fillet skin-side down with the tail pointing toward your knife hand. If the skin is still attached to the fish, fold the fillet away from the body so it lies flat on the cutting board.

Hold the narrow tail section firmly. Insert the blade between the flesh and skin, keeping the knife almost parallel with the cutting board. Angle the cutting edge slightly downward toward the skin.

Move the knife forward with a gentle sawing motion while pulling the skin in the opposite direction. The knife should slide between the flesh and skin without cutting through either. Keeping the blade flat is more important than using force.

A flexible fillet knife makes this job easier because the blade can bend slightly against the cutting board.

Remove Bones and Trim the Fillets

Run your fingertips over each fillet to locate any remaining bones. Rib bones are usually easy to see and feel. Pin bones may run through the centre portion of the fillet and can be removed with clean pliers or trimmed out with a narrow V-shaped cut.

Some species require additional attention. Northern pike contain a row of Y-bones that must be removed with specialized cuts. Large trout and whitefish have noticeable pin bones that are easily pulled with fish-bone tweezers. Walleye and perch have pin bones along the lateral line, where the ribs were removed. Make a cut above and below the pin bones and remove the thin strip.

Clean and Chill

Rinse fillets only when necessary, using clean, cold water. Excessive washing can soften the flesh and spread bacteria around the cleaning area. Often, wiping away scales, blood, or debris with a damp paper towel is sufficient.

Pat the fillets dry and place them in a clean container over ice. Do not let the meat sit in melted ice water. If the fish is eaten within a day or two, refrigerate it at 4°C or colder. For longer storage, package the fillets carefully and freeze them as soon as possible.
