One of the most pleasant yet difficult tasks is cleaning your catch, especially if you do not know the starting point.

Whether you are an ultimate first-timer or a person who wants to add a pinch of perfection to their crafts, knowing how to gut and clean a fish properly is important for both cleanliness and taste.

Today, I will take you through the tools and techniques, waste disposal, and knives required in this guide. If you have ever asked yourself the question of how to gut a fish correctly, then you are in the best place.

Everything You Need to Gut and Clean a Fish

Let’s start with the basics. The proper setup will make the whole operation easier and risk-free.

Tools You’ll Need:

  • A sharp fillet or boning knife
  • Cutting board or a flat surface
  • Gloves (optional but helpful)
  • A bucket or bowl for guts
  • Running water or a rinse station
  • Paper towels or clean cloths
  • Trash bags for disposal

Having a sharp, sturdy knife is the most important tool of all.

How to Gut a Fish Step by Step

Now, let’s dive into how to gut a fish step by step. To begin with, always work in a clean area. And rinse the fish before getting started. 

1. Rinse the Fish

Firstly, start by rinsing the fish under cold running water to remove dirt, slime, and debris.

2. Lay the Fish on Its Side

Secondly, place the fish flat on the cutting board, belly facing you.

3. Make the Belly Incision

Thirdly, using the tip of your knife, insert it near the anal vent and slice upward toward the head, just deep enough to cut through the belly without damaging internal organs.

4. Remove the Guts

Then, open the cavity and remove the guts with your fingers. Pull gently to remove everything in one motion. Need to be cautious near the gallbladder (a small green bag) because upon puncture, this structure may leak bitter fluid.

5. Clean Out the Bloodline

Lastly, along the backbone, you’ll find a dark line of blood; scrape this out using your knife or a toothbrush and rinse thoroughly.

How to Clean a Fish After Gutting

Once the fish is gutted, the cleaning process ensures it’s ready for cooking or storage. To clean a fish after gutting, start by scaling the fish, rinsing it, and patting it dry.

Follow these steps:

1. Scale the Fish (if needed)

To begin with, using the back of your knife or a scaler, scrape the fish from tail to head until all scales are gone. Then, rinse well.

2. Rinse Again

Next, flush the inside and outside of the fish under running water to remove any leftover blood or tissue.

3. Pat Dry

Finally, use paper towels to dry the fish before refrigerating, freezing, or preparing.

How to Dispose of Fish Guts

The proper disposal of waste should be of the same importance as gutting. So, here’s how to dispose of fish guts responsibly:

  • Put a garbage bag around it and freeze it till garbage day.
  • Plus, use a fish-safe way of composting the waste.
  • Moreover, you can also add it to your garden to serve as a free fertilizer.
  • In addition, do not dump in the open water; it may cause an imbalance to the ecosystem or cause unwanted fauna.

Eventually, clean your surface and tools immediately so that you can avoid odor or contamination.

Why the Knife Matters When it Comes to Gutting Fish

When you’re learning how to gut and clean a fish, the knife you use makes all the difference. A blunt or unbalanced knife will result in tearing, sloppiness, and even injury. With the right blade, you can make clean cuts, fillet easily, and avoid struggling with scales, bones, or skin.

So, what should you look for?

  • Razor-sharp edge with a low blade angle
  • Corrosion-resistant material
  • Comfortable, non-slip handle
  • Long-lasting edge retention
