As a born and raised Southerner, there is one particular type of fish that is near and dear to my heart: catfish. I grew up eating loads of catfish, fried, of course. Therefore, I’m surprised when people ask the question, “Can you eat catfish?” Of course, you can! I still adore it and anytime I’m back home the first thing out of my mouth is “Fix me up a mess of catfish.” The problem is, while all catfish is edible, not all species are good to eat. I’ll explain all of that, plus a lot of other things about catfish, in this article.
As you may have guessed, I don’t live in the South right now — at least not in the deep South. You may also wonder why I need to go back home to the South to get catfish. Can’t I cook my own catfish? Of course, but there is a problem. I’ll get to that. Regardless, if you want to get me riled up, tell me catfish is bad. Tell me it’s a food you should avoid at all costs.
There are reasons why we are sometimes told to avoid catfish. There are also reasons that many people outside the South think catfish is nasty.
Not All Catfish is Good to Eat
Looking at a catfish, I can understand why people would question whether you can eat them. They are not pretty. And, as I said, while all catfish are technically edible, they are not all good to eat. Some are downright foul. First of all, the catfish imported from Vietnam is not good to eat, and I’m not even questioning what type of catfish it is.
But, the fact is there are hundreds of species of catfish! Only a relative handful are good to eat. Not all catfish are delicious, to say the least. We have many species in the South, which depending on who you ask, are considered bad eating.
One of the best catfish to put on your plate, and one of the most popular and well-studied, is the channel cat, so named because they tend to live in fast-running waters or “channels.” This species, (Ictalurus punctatus) goes by many other common names:
- blue cat
- blue channel
- spotted cat
- speckled cat
- fiddler cat
- blue fulton
- chucklehead
Blue cat, however, could be considered a misnomer simply because channel cats are often confused with another species, Ictaluris furcatus, or blue catfish. The two look very similar and can have similar coloration, but blue cats don’t have the small black spots down their sides characteristic of channel cat.
It doesn’t matter, though, since they are both great eating. The channel cat is probably the most popular catfish in the South. It is the most widely caught and the most widely farmed, often raised alongside other fish. You cannot get a better tasting catfish, no matter how you prepare it, although the true blue catfish is also very excellent.
Why I Had To Go Back Home To Get Good Catfish (Up Until Recently)
In the waters where I live, in the Chesapeake region, there have long been no catfish that are good for eating. Or, at least very few you have a chance of catching. This answers the question I started with at the beginning: Why can’t I get a decent catfish here and why do I have to “go down South” to get it.
This is changing, however. At present, blue cat (Ictaluris furcatus) have been introduced into the waters of the Chesapeake Bay region. It’s not good news! Blue cat in these waters are an invasive species, as many catfish can become when improperly introduced to new habitats.
Having been introduced into the region in the 1970s, their numbers are now getting out of control. They have no natural predators in this habitat and there is little to stop them from severely upsetting the ecosystem and endangering native species such as blue crabs, or menhaden.
Fishermen are being encouraged to catch as many blue cats out of these waters as they can, and many chefs, with Southern origins or not, are taking advantage of the growing supply of fresh blue catfish, offering up a real Southern delight on their menus.
It could be many folks will reassess their opinion of catfish if they give some a try. I had a great fried catfish dinner at Gertrudes, in Baltimore (located inside the Baltimore Museum of Art) although we don’t put gravy on catfish where I come from, nor a hard crunchy topping. We also don’t put it on top of vinegary turnip greens. But, still, it was delicious!
And now, I can regularly purchase locally caught blue cat at Whole Foods! Pretty awesome but it’s hard to celebrate knowing the fish is harming the waters of the Chesapeake region.
Reasons To Avoid Catfish?
Given my love for catfish and my Southern heritage, you can understand why I did not respond well to this video. It portrays catfish in truly negative light, saying that there are several reasons you should avoid eating it at all costs.
To be honest, I do not agree with anything in the video. I have no use for lists of the worst and best foods. However, the statements made about catfish are a good lesson in examining nutritional claims. Let’s look at some of them.
1. Catfish is a “bottom feeder”.
Are catfish bottom feeders? Yes — but being a bottom feeder is a characteristic that is common among the most popular seafood. Lobster, the mainstay of many 4 and 5-star restaurants, is a bottom feeder. I might point out though, that people who live in trailer parks don’t eat lobster. They eat catfish.
Yes, there are cultural connotations at work here, or no one would malign catfish for being similar to another ‘gourmet’ food. There was a time, after all when lobster wasn’t so gourmet. People ask is catfish dirty while going out of their way to find fresh oysters which spend their lives living in muck and whose shells are often full of mud, sand, worms, and who knows what else. I think you get my point. Catfish is absolutely squeaky clean compared to certain seafood. And, I’m not advocating you should ever eat catfish raw, the way people often eat oysters.
2. You dredge it and fry it
Okay, so is catfish a problem because it is a bottom feeder and full of “toxins” and “carcinogens” or is it the preparation method? Two different things.
There are many ways to prepare catfish, but you can’t mix and match your premises for objection. Would catfish not be on the list if I baked it, grilled it, or simply sauteed it? Or would it be further down the list?
In other words, the preparation method is a variable that can be controlled, but catfish being “full of toxins” cannot be controlled.
3. Catfish don’t have many nutrients
Bull baloney. It’s full of nutrients.
Here is some data for ONE FILLET (about 87 grams) of catfish, and breaded and FRIED:
| Protein | 15.74 grams |
| Calcium | 38 mgs |
| Iron | 1.24 mgs |
| Magnesium | 23 mgs |
| Phosphorus | 188 mgs |
| Potassium | 296 mgs |
| Sodium | 244 mgs |
| Zinc | 0.75 mgs |
| Copper | 0.088 mgs |
| Manganese | 0.035 mgs |
| Selenium | 12.1 mcg |
It also provides a good mixture of B vitamins such as Thiamin, Riboflavin, Niacin, B6, Folate, Pantothenic acid, and B12, as well as vitamin A. Of course, your actual mileage will vary.
But, let’s look at those terrible fats:
| Saturated Fat | 2.8 grams |
| MonoUnsaturated Fat | 4.8 grams |
| Polyunsaturated | Fat 2.8 grams |
The fact is that nutritionally, this is a good fatty acid distribution, like with most fish. This is part of the reason why fish is considered to be so healthy. And yes, some of those polyunsaturated fatty acids in catfish (this was channel cat, by the way, which are river runners and lean) are Omega-3 EPA and DHA.
Sure, catfish is no salmon, but many salt-water non-bottom feeder fishes can also be accused of not being salmon. We do not rate the nutrition of fish based on how much it is not salmon.
Still, we can talk about those healthy fats in salmon and realize that there is a culinary difference between salmon and catfish. First of all, most catfish are eaten at a younger age. Old catfish are fat catfish and fat catfish are not as palatable. You may dream of catching a 50-pounder, but he will not taste as good as a ten-pounder. I guarantee it — take it from a true catfish fisherman and eater.
PCBs, Mercury, and Other Toxins
As far as toxins, guess where they are stored? In the fats. Comparing a relatively lean fish (as consumed) to a very fatty fish and then saying that the lean fish has more toxins because it is a bottom feeder is misleading. The older and fattier the fish, the more the potential for heavy metals like Mercury and PCBs, etc.
Is it possible that some freshwater fishes can have more PCBs? Yes. However, as one commenter on the video’s page pointed, the majority of catfish consumed in the states are farm-raised, pellet-fed fish. Not “bottom feeding”. I grew up eating mostly fresh-caught catfish from wild sources, but even so, we weren’t above going to the catfish farm.
Avoid Imported Farm-Raised Catfish
I brought up farm-raised catfish for a reason. There are many catfish farms in the South. However, if you live further north and you buy ‘fresh’ catfish from the grocery store (which will have been previously frozen), it will most likely be catfish that was farm-raised in Vietnam or somewhere else in Southeast Asia.
The same problems I mentioned concerning imported farm-raised shrimp and tilapia are found in imported catfish. Yes, you should avoid imported farm-raised catfish. The practices there would not pass muster in the United States, and antibiotics that are banned for use by the FDA are used. Plus, it isn’t a good catfish. It does not taste the way catfish should taste.
