How to clean and fillet a catfish 

how to clean a big catfish

In order to fillet a catfish, you will need some cold water cats. You will see, your catfish is still lively after sitting in a bucket. Moreover, you will need some snippers to let your catfish lay flat. Just cut your catfish right off and they lay down flat. As a result, the fish will cooperate and will become easier to cut. Simultaneously, the catfish will seem hard where you will find a spot right behind it.

Afterwards, slide or slice right down your rib cage. Hence, a sound of pop will appear just like a walleye. Next, turn your catfish and flay that entire side of meat off all the way down 

After flipping your catfish, you will find a nice big chunk of meat. When you see it, do the other side quickly. Alongside, you are to keep your knife at an angle to cut over a back plate and slide the juicy one all the way down through that tail. Similarly, flip that cutting piece over the plate and discard it in trash.

Now use a clean fillet and make sure there are no hard bones. And if you miss any chunk, take that piece off and slice off nicely. After talking your meat, fillet it just like you would do to a wallet. And remember that there will be no scales in your meat. Then, clean your fillet and meat’s pieces to keep them fresh.

How to fillet a catfish with a knife

In order to fillet a catfish, use an electric knife and put your fish on ice before cleaning it. Make sure your flesh is soft and makes the job easier. First of all, take your fish out of the eyes and straighten its body. Then hold your fish with your left hand. Or you are right-handed, grip the fish by placing your thumb and forefinger behind the pectoral fins.

Likewise, your catfish’s head will be in the palm of your hand and you are to lay your fish on the other side where there is a flat surface. Nonetheless, this surface is located at the end of your ribcage.

Next, use your right hand and angle it with your electric knife and make it parallel to the ribcage. When you are done, start cutting your fish at an angle towards your fish’s backbone.

Once the backbone is reached, turn the blade of your electric knife keeping it parallel to the backbone. Now continue to cut along the backbone until you reach your fish’s tail. And once you reach the tail, stop cutting and use your blade to flip the fly over.  Again, use your electric knife to cut your meat from its skin. Therefore, you will get a boneless filet ready for the oven grill or fryer. 

If you like to eat backbone, simply cut it off

behind the rib cage and remove the fins. As catfish is a freshwater fish, it gets cleaned easily and swiftly with an electric knife.  

How to fillet a catfish 

First thing you will need to do is, go right behind the gill plate and the pectoral fin. Then make your first little incision all the way from fine down. Then go ahead and repeat the same thing on the other side of the meat and go ahead and go right behind the spine.

Make sure you are going to slide the knife in and just try to ease the knife right along your catfish’s bone. Sometimes it is easier to turn your fish upside down to the knife spacing up towards you from the spine. Once you get about down to the adipose fin here you’re just gonna slide the knife all the way.

So it pops out by the ventral fin and then just eases your fin all the way down. Now you will get a nice clean cut. Repeat this step on both sides of your meat.

Then start peeling your catfish’s skin over the rib cage and let your knife work right down the outside of those ribs. Don’t worry about the skin being on but if that bothers you, hold it and slide the knife in and just ease it on down. As a result, the skin from your catfish will get separated and you will have a skinless fillet for freezing. 

Repeat the same thing on the other side of your catfish and store it for a long time in a freezer or put it in a freezer ziploc bag. Then squeeze all of the air out of your ziploc bag and close it off.

To fillet a catfish, you need one sharp fillet knife and do not forget to see if your catfish has lots of flavor in the skin or not. So ideally, you will not even have to remove the skin of your catfish. But if you want to leave the skin on, you should remove the slime too.

And to remove your catfish’s slime, you will have to scrape its skin right down until there is no slime left. For washing that slime off in the sink, you have to get a dollar knife and just keep sliding back and forth.

Now you will have to cut right along your catfish’s backbone towards the tail fin. In addition, you are going to find some contaminants in the fat which typically would be in your catfish’s belly. Alongside, it will be easier to work with your catfish by leaving its belly and you are to cut right behind the head.

When you get to the rib cage, cut around it and keep working the knife along the bones. Afterwards, go right around your rib cage and break to the tail end along the backbone. Consequently, you will have one completely boneless fillet which is required for washing.

On the other hand, you will get a dark mussel which you are to remove that dark mussel by keeping a thin layer right under your fish’s skin. Right now, you have two nice boneless fish.

Buying Guide

For acquiring a nice electric fillet knife, we must make sure that we are not missing out on any important terms. Such as- handle of knife, materials, size, knife sheath, and so on. For this reason, I am going to show you some essential features that you must look for while purchasing an electric knife for your catfish.

Safety features

While choosing an electric fillet knife, make sure it has all safety features included. Indeed, an anti-slip catfish knife will give a commendable feature of easy grip with its handle. Contrastingly, there are some electric fillet knifes that never let the knives come out unexpectedly.

Again, a knife with cooling or ventilation system plays a great role to cushion an overheating motor’s effects. In the same way, fillet knives with portable storage cases ensure safety while using them.


Fine handle materials is something you must consider as your first priority while purchasing a fillet catfish electric knife. Do not go with the non-conductive materials of handle as they seem difficult to hold. Hence, it will be wiser to opt a fillet knife where an insulated handle is adjusted.

But if you don’t feel comfortable with a vibrating or overheated electric knife, just go with an ergonomic designed electric knife. Here, you will get a non-slip grip and safety features for sure.


Before acquiring a fillet knife, be certain of the type of blade it has. If you are comfortable with a straight edge fillet knife go with that. Or else, a serrated blade can be a cherry on top for you. Similarly, blades that are easy to remove tend to be more convenient while using.

Besides, there are many blades which offer versatility within multiple lengths. Hence, cutting other products than meat will become easier for you.

Some blades made with stainless steel are nowhere even mediocre. Indeed, blades with high-carbon steel last longer than any ordinary fillet knives.

Cordless or corded fillet knife

Although corded fillet knives and cordless fillet knives are advantageous enough, they are different from each other merely.

In particular, cordless fillet knives take the help of batteries to run. Therefore, you will not have to rely on any electric outlet or plugging source. On the other hand, a corded electric fillet knife works after getting plugged in an electric outlet or socket. Or an adapter can be better even for a corded knife. But if you want a powerful electric knife, then corded ones would be a better choice.
