Cutting board: Use a non-slip cutting board made specifically for fish preparation.

Step-by-Step Process to Clean Catfish

1. Prepare the Workspace

Ensure your cutting board and tools are clean before beginning. Place the catfish on the cutting board and wear gloves to prevent slips. Always work in a well-ventilated area to make the task easier.

2. Remove the Catfishs Slime

Catfish are notorious for their slimy coating, which makes handling difficult. Use a knife or scraper to clear the slime under running water. You can also use coarse salt to scrub the surface.

3. Cut off the Fins

Use the fillet knife to remove sharp dorsal and pectoral fins by slicing down at an angle. This prevents accidents when handling the fish further.

4. Make the Initial Incision

Position the fish belly-up and use your knife to make a shallow cut from the anal opening toward the head. Avoid cutting too deep to prevent puncturing the intestines.

5. Gut the Fish

Carefully remove the internal organs by scooping them out with a finger or spoon. Rinse the cavity thoroughly with cold water.

6. Remove the Head

Grip the head firmly and make a cut just behind the gills. Apply steady pressure with the fillet knife for a clean removal.

7. Skin the Catfish

Using pliers or a skinning tool, grab the tough skin near the incision at the head. Pull firmly to peel the skin toward the tail. Repeat on both sides until the fish is clean.

8. Fillet the Catfish

Use your fillet knife to cut along the backbone from head to tail, separating the fillet from the ribs. Flip the fish over and repeat on the other side. To sharpen your knife for precision, read this step-by-step sharpening guide.
