Are you one of those seafood enthusiasts who would rather buy filleted fish than to buy a whole one just to avoid looking at the dead fish’s eyes giving you death glares?
Well, try looking at the funny-looking catfish, and it will intrigue you rather than scare you. With peculiar barbels or feelers around the mouth that look more like whiskers, its face from the front side looks a bit like a cat, hence the name.
Another reason for its peculiar name is that it does not have scales on its body. Some have a naked smooth body; a few may also have bony plates which provide protection.
But don’t be fooled by its cuteness; they do have spines containing venom, which is very painful if your skin gets punctured while handling live catfish. Want to know more? Read the interesting facts below.
Does Catfish Have Bones?
There are more than a thousand varieties of catfish which have been identified by aquatic life experts. Some catfish are small to normal size and are raised in fish farms, while other big ones are found in lakes and marine environments.
Each one of these different types of catfish have a very similar bone structure. All of them have a rigid endoskeleton consisting of one large spinal column in the middle under the dorsal fin, like a backbone.
There are smaller bones branching out of this in an orderly fashion, which are spread out much like ribs in mammals. The function of this endoskeleton is to give the body of the fish its present shape and the strength to bear pressure underwater.
The skull of the catfish is made up of overlapping bones in the head region. The catfish have what is called dentary bones in their jaws instead of individual teeth, which are hard and abrasive.
After the catfish is filleted, gutted, and headed, its frame remains which consists of the backbone and rib bones. These frames are used to make dietary supplements for humans because of the high quality of calcium found in them.
The head is also very large and contains a great deal of bone. Animal feed is also made from processing the catfish bones.
Which Fish Has No Bones To Eat?
Almost all fish have some sort of bones which are basically cartilaginous more than bony. This is because Fish are vertebrates, meaning they have a backbone or a spine.
However, some fish like Tuna and halibut have big meaty portions with little or no bones, which are easily carved into stakes. So you might think that they do not have any bones in them.
Some other fish like mahi-mahi, white fish, and perch have a big bone in the center with few side bones that are easily removed, and most of the flesh is practically boneless.
The tastiest and most popular fish, which are mostly available in the boneless form, is Tuna, Mackerel, and Arctic Salmon. Tuna is popular both in canned and fresh forms.
The only fish that comes to mind which actually contains no bones is the slime eel. This hagfish belongs to the invertebrate class of aquatic animals. This practically means it has no backbone running down its middle from its skull to its tail.
Every other fish not only has a spine but also has additional bony fin rays in their fins: caudal as well as pectoral. These fin bones are not connected to the main spine but are attached to the muscles in adjoining vicinity.
Are Catfish Bones Dangerous? What Happens If You Eat A Catfish Bone?
Catfish have a normal endoskeletal system consisting of a big backbone or the spine and some smaller bones attached to the spine, much like the ribs in humans.
But fishbones are not hard bones like other mammals on land; rather, they are cartilaginous. Catfish also have these cartilaginous bones, which are a bit difficult to remove in raw fish.
But during the process of cooking, they become tender. In fact, catfish bones are a little brittle and tender to begin with, and get further weakened over a heated pan when cooked encased in the flesh.
The bones are perfectly edible but could be a bit more challenging than eating just the fleshy part. Normally you would not face any problem swallowing these small weak bones.
Once these get inside your digestive system without sticking in your throat, your digestive juices can break them easily and dispose off them the usual way.
Sometimes, however, if you are not paying attention while eating, the bones can pinch your throat a bit, but they are so thin and weak that you don’t feel any pain or even discomfort.
However, some wide varieties of catfish can have a stronger bone structure which still retains enough strength to puncture your esophagus if stuck while swallowing. In these rare instances, the harm could cause trouble swallowing, so be careful while eating bigger catfish.
Can I Leave The Skin On The Catfish?
Catfish are notorious for having one of the most difficult skin to remove when it is raw. So you are right to wonder if you should go through the hassle of cooking with skin on does not take anything away from the taste and flavor.
Whether you skin it or you don’t, be mindful of a few facts. Firstly, the difficulty in removing the skin in raw fish; the skin can easily comes off the meaty part once it is properly cooked.
But there is a flip side; the skin curls during cooking because it loses moisture. You can overcome this problem by scoring the raw fish. These fissures can let moisture out without deshaping the whole fish.
There is a common advantage of cooking with skin on, which is the moisture that the meaty part retains while cooking, which leaves a juicy moist flesh for you to enjoy.
Be mindful, however, to avoid such recipes which require you to dip the fish in some batter that would make the skin of the fish stick to the pan, which spoils the taste.
Step By Step – How To Remove Catfish Bones?
Catfish features very regularly on the menus of many seafood consumers. The reason for its popularity is its yummy flavor and the fact that it is easily cooked.
But the real test is the process of deboning before filleting it. Following are the step by step guidelines to debone the catfish for first-timers:
- Step One: If you have bought a live catfish, the first step is to kill it. An easier and less painful way for the fish is to just decimate the head, which would paralyze and then kill it.
- Step Two: For cutting the head, you have to find the head case, then see the base skin and cut through it.
- Step Three: Make a diagonal cut from the start of the dorsal fin to the area before the pelvic fin. The purpose of diagonal cutting is to avoid puncturing the internal organs. If you put enough pressure, you can easily cut through the rib bones.
- Step Four: While making a deeper cut, you can feel the backbone through your knife. Now turn the knife towards the tail and keep cutting along the spine till you reach the rear side of the fish. Leave an inch of tail behind.
- Step Five: Flip the catfish and cut from the edge of the tail where it connects the skin to the fat. This way, you are basically skinning the fish. Flip the fish and do it again, now from the opposite side. If the skin is tough, as is the case with bigger catfish, use pliers instead of a knife to peel it off; cut the catfish fins from the back and stomach.
- Step Six: Some rib bones will remain inside the meat, so you need to carve these out.
- Step Seven: Some meat remains in the head area, you can remove this too if you don’t want to waste any meat.
- Step Eight: Wash the fillet thus obtained with cold water to remove blood and slime.
