How to serve catfish by age

6 months+

Soft flakes or fish cakes

Bake or poach catfish until it is opaque and flakes easily (145°F / 63°C), remove every bone and the skin, and offer large soft flakes, or mix with mashed potato and shape into finger-sized fish cakes.

Size: Large soft flakes, or fish cakes shaped like a finger, about 6–8 cm long and 2 cm wide (2½–3 × ¾ in).
Check before serving: Run your fingers through every flake to feel for bones. Cooked catfish is white and opaque all the way through and flakes easily with a fork.

US and UK advice differ here. The AAP suggests mashed food or soft pieces no larger than ½ inch; the NHS suggests soft finger-sized pieces your baby can hold in their fist. Both agree the food must squash easily.

Always have your child sit upright in a high chair or at the table, and stay with them the whole time they eat. Keep to the size and texture for their stage. Every baby develops on their own timeline.

How to prepare catfish

1
Thaw frozen catfish in the fridge overnight. Bake a skinless fillet at 200°C (390°F) for about 10 to 15 minutes, or poach it, until it's opaque and reaches 145°F (63°C) in the thickest part.
2
Let it cool, then pull it apart with your fingers, feeling every flake for bones. Remove any skin.
3
Offer large flakes, or mix with mashed potato and shape into finger-sized cakes. Don't add salt.
4
First time? Pick a day your baby is well and at home, so you can stay nearby for several hours afterward. Fish can cause a delayed reaction: see when to call the doctor.

How much to offer

For the first taste, offer a small amount: a few flakes or one small fish cake. For ages 1 to 3, the FDA suggests a fish serving of about 1 oz (28 g), twice a week, from its 'Best choices' list, which includes catfish. Your baby decides how much to eat.

Common mistakes

Missing bones

Fillets can still hide small bones. Feel every flake with your fingers, even in fillets sold as boneless.

Undercooking it

Cook it to 145°F (63°C), until it's opaque and separates easily with a fork. Never offer raw or undercooked fish.

Serving fried or breaded catfish

FoodData Central lists about 280 mg of sodium per 100 g for breaded, fried catfish, against about 120 mg for plain baked farmed catfish, and the NHS says frying adds fat and that baked, steamed or grilled fish is a healthier choice. Make your own baked fish fingers instead.

Using catfish caught by family or friends without checking

The FDA says catfish caught by family or friends is more likely to have a local fish advisory because of mercury or other pollutants. Check the advisory first. If there isn't one, the FDA says children under 6 should have only 1 to 2 oz (about 28 to 56 g) of that fish that week, and no other fish.

Where US and UK guidance differ on catfish

United States(AAP and CDC)Your setting

Catfish is on the FDA's low-mercury 'Best choices' list and among the fish it names as even lower in mercury. For ages 1–3, a serving is about 1 oz, twice a week. For catfish caught by family or friends, check local fish advisories first.

United Kingdom(NHS)Your setting

Catfish isn't on the NHS list of oily fish, so the NHS weekly oily-fish limits don't apply. Children under 16 shouldn't have shark, swordfish or marlin. Baked, steamed or grilled fish is a healthier choice than fried.

We cover US and UK guidance in detail. Elsewhere, check your national health service's advice too.

Questions parents ask

Can catfish be a choking hazard for babies?

Cooked, flaked catfish is a low choking risk, but bones are a hazard. Check every flake with your fingers before serving. Always cook catfish fully, and never offer raw or undercooked fish.

Can babies be allergic to catfish?

Fish is a common allergen. Introduce it on its own first, in a small amount, and watch for signs of a reaction. If your baby reacts to catfish, talk to your pediatrician before offering other fish. People allergic to one type of fish often react to other types.

Is catfish healthy for babies?

A source of protein, vitamin B12 and selenium: FoodData Central lists about 2.8 mcg of vitamin B12 per 100 g of cooked farmed catfish. It has less omega-3 fat than oily fish such as salmon, and it is not a major source of iron.

Is catfish safe for babies?

Yes, from around 6 months, cooked until opaque and flaky, with every bone and the skin removed. Catfish is on the FDA's low-mercury 'Best choices' list.

Is catfish high in mercury?

No. Catfish is on the FDA's 'Best choices' list and among the fish it names as even lower in mercury. The FDA notes that catfish caught by family or friends is more likely to have a local fish advisory, so check that first.

Can I use frozen catfish?

Yes. Frozen catfish works just as well. Thaw it in the fridge overnight, then cook it until it's opaque and reaches 145°F (63°C).

How often can babies eat catfish?

The FDA's twice-a-week fish advice is for children aged 1 to 3, with a serving of about 1 oz; it doesn't give a serving size for babies under 12 months. US and UK advice differs: see the guidance note below.

If your baby refuses catfish

Many babies need 10 or more tries before they accept a new food. Keep offering it alongside foods they already like.
Mix flakes into foods your baby already likes, such as mashed potato, rice or pasta.
Try fish cakes: they're easier to hold than loose flakes.
Eat some yourself at the same meal. Babies copy what they see.

Never force or pressure your baby to eat. Some days they'll eat more, some days less, and that's normal.

Buying and storing catfish

Keep raw catfish in the fridge and cook it within 2 days, or freeze it. Thaw frozen catfish in the fridge overnight.
Cooked catfish keeps for 3 to 4 days in a covered container in the fridge. Rice dishes are the exception: cool them within 1 hour, keep them in the fridge for no more than 1 day, and reheat them only once.
Fish cakes can be frozen for 3 to 4 months. Reheat only once, to 165°F (74°C), until steaming hot, then let them cool before serving.
Throw away any food left out at room temperature for more than 2 hours (1 hour if it's hotter than 90°F / 32°C).

When to talk to your doctor

Contact your pediatrician, GP or health visitor if:

Your baby vomits a few hours after eating fish. This can be FPIES, a delayed type of food allergy that fish can trigger. If they vomited once or twice and seem alert and like themselves, call your pediatrician or GP. If they vomit again and again, or are pale, floppy, very sleepy or hard to wake, call your emergency number.
You notice mild signs of an allergic reaction after eating, such as a few hives or a little vomiting. See signs of a reaction.
You're worried about how much your baby eats, their growth, or they refuse most solid food for weeks.

Call 911999your local emergency number (such as 112 in Europe or 000 in Australia) now if your baby has trouble breathing, wheezing, can't cough or cry, has lips, mouth, tongue or throat that suddenly swell, or becomes pale, bluish, floppy or unresponsive. Also call if hives come with repeated vomiting.
