How to Clean a Whole Fish
Cleaning a whole fish requires three distinct motions: removing the scales from tail to head, eviscerating through the belly, and clearing the bloodline along the spine. Use a sharp, flexible blade and work on a stable, nonslip surface to ensure clean cuts without piercing the intestinal tract.
Keep the fish cold and the workspace firm.
A room-temperature fish is slippery and difficult to handle; keep it on ice until you are ready to start. Lay a damp kitchen towel under your cutting board to keep it from sliding while you apply pressure.

The Gill-to-Belly Cut
The secret is to keep your knife blade angled slightly upward to avoid puncturing the gut, which taints the flesh. Start at the vent and slide the blade shallowly toward the gills.
The method.
Scale the fish
Hold the fish firmly by the tail. Using the back of a dull knife or a scaler, scrape firmly against the grain of the scales, starting at the tail and moving toward the head. Rinse frequently to clear away debris.
Remove the fins
Use kitchen shears to trim the dorsal, pectoral, and ventral fins. Snip them close to the body to prevent ragged edges.
Open the belly
Insert the tip of your knife into the vent—the small hole near the tail end of the belly—and slide it forward through the skin until you reach the gills. Stop before you cut into the head itself.
Eviscerate
Pull the guts out with your fingers in one motion. You will see a dark red line running along the spine; use your thumb or the tip of a spoon to scrape this bloodline clean under cold running water.
Remove the gills
Grasp the gills firmly and pull them out. If they are stubborn, use your shears to snip the connective tissue at the top and bottom of the gill plate.
When it doesn't go to plan.
Work near a sink or keep a bucket of cold water nearby to rinse the fish immediately after every step.
If the scales are flying everywhere, perform the scaling step inside a large plastic bag to contain the mess.
Check for any remaining pin bones or membrane tags by running your thumb along the inside of the cavity.
The ones that keep coming up.
How do I know if the fish is fresh?
The eyes should be clear and slightly bulging, not sunken or cloudy. The gills should be bright red, not brown or grey, and the skin should be firm to the touch.
Does it matter which knife I use?
A flexible fillet knife is best because it bends with the anatomy of the fish, minimizing waste. Avoid heavy, thick-bladed chef's knives which tend to tear the flesh.
