How to Scale and Gut a Fish
How do you scale and gut a fish? Scrape the scales off from tail to head with the back of a knife, slit the belly from the vent to the gills, pull out the innards, cut out the gills, and rinse the cavity under cold water. A flexible fillet knife handles the belly cut and later filleting: the Dalstrong Gladiator Series 7" Flexible Fillet Knife ($79) is German X50CrMoV15 at 54–56 HRC. Kitchen scissors ($79) make cutting fins and gills easier.
What you need
- Gladiator 7" Flexible Fillet Knife ($79) or Shogun 6" Fillet Knife ($139)
- Professional Kitchen Scissors ($79)
- A large plastic board, or newspaper on the counter
- A bowl of cold water
Step 1: Scale
- Work in the sink or inside a large plastic bag to contain flying scales.
- Hold the fish by the tail.
- Scrape from tail to head with the spine of a knife or a scaler, using short strokes.
- Don't forget near the fins and the belly. Rinse.
Step 2: Trim fins
Snip off the dorsal, pelvic and anal fins with scissors. Some are spiny, so be careful.
Step 3: Gut
- Insert the knife tip into the vent near the tail, edge facing the head.
- Cut shallowly up the belly to the base of the gills. Keep the cut shallow so you don't pierce the innards.
- Open the cavity and pull out the innards.
- Scrape out the dark bloodline along the spine with a spoon or your thumb.
Step 4: Remove the gills
Gills taste bitter. Cut them free at the top and bottom with scissors and pull them out.
Step 5: Rinse and dry
Rinse inside and out under cold water and pat dry. Cook whole, or fillet it; see how to fillet a salmon.
