Quick answer
Babies can eat sea bass from around 6 months, once they show signs of being ready for solids. Prepare it as shown below.
How to serve sea bass by age
6 months+
Soft flakes or fish cakes
Bake or poach sea bass 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 sea bass 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.
9 months+
Small flakes
Offer small, boneless, fully cooked flakes for pincer-grasp practice, or stir into rice, pasta or mashed vegetables.
- Size
- Flakes no bigger than about 1 cm (just under ½ inch).
- Check before serving
- Feel every flake for bones before serving.
12 months+
Pieces or in family meals
Serve bite-sized pieces, fish cakes, or sea bass in family dishes such as fish pie or pasta. Always cook it fully.
- Size
- Bite-sized pieces about 1 cm (just under ½ inch), or fish cakes.
- Check before serving
- Feel every flake for bones before you mix it into a dish or shape it into cakes.
18 months+
Flaked into family meals
Serve sea bass in pasta, rice, soft tacos or fish cakes, baked rather than fried. Keep checking for bones; they're easy to miss in mixed dishes.
- Size
- Bite-sized pieces about 1 cm (just under ½ inch).
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 sea bass
- 1
Check the label for the type: black sea bass is a low-mercury 'Best choice' on the FDA list, while Chilean sea bass and ocean striped bass are 'Good choices', with more mercury.
- 2
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. Don't add salt.
- 3
Let it cool, then pull it apart with your fingers, feeling every flake for bones. Remove any skin.
- 4
Offer large flakes, or mix with mashed potato and shape into finger-sized cakes.
- 5
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 black sea bass. Chilean sea bass is a 'Good choice', and the FDA gives no 'Good choices' amount for children. Our suggestion is to serve it only now and then. Your baby decides how much to eat.
Common mistakes
Not checking the type
'Sea bass' covers several fish. The FDA lists black sea bass as a 'Best choice', and Chilean sea bass (Patagonian toothfish) and ocean striped bass as 'Good choices', with more mercury. For your child's usual fish meals, the FDA's advice is to choose from the 'Best choices' list.
Missing bones
Sea bass 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 flakes easily. Never offer raw fish such as sushi, crudo or ceviche.
Serving the crispy skin
Sea bass is often cooked skin-on until crisp. Take the skin off for babies: it's chewy and hard for them to break down.
Where US and UK guidance differ on sea bass
United States(AAP and CDC)Your setting
The FDA lists black sea bass as a 'Best choice', and Chilean sea bass and ocean striped bass as 'Good choices'. For children, the FDA suggests 2 servings a week from 'Best choices' (about 1 oz each at ages 1–3) and gives no 'Good choices' amount for children, so our suggestion is to treat Chilean sea bass as an occasional fish for your child.
United Kingdom(NHS)Your setting
The NHS doesn't single out sea bass, and it isn't on the NHS oily fish list, so the NHS weekly oily fish limits don't apply. European sea bass isn't on the FDA chart either, so our suggestion is to treat it as an occasional fish. 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 sea bass be a choking hazard for babies?
Cooked, flaked sea bass is a low choking risk, but the CDC lists bones in fish as a choking hazard. Check every flake with your fingers before serving. Always cook sea bass fully, and never offer raw or undercooked fish.
Can babies be allergic to sea bass?
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 sea bass, talk to your pediatrician before offering other fish.
Are sea bass healthy for babies?
A source of protein and selenium, with some omega-3 fat: FoodData Central lists about 24 g of protein, 47 µg of selenium and 0.6 g of DHA per 100 g of cooked sea bass (mixed species). It has less omega-3 fat than oily fish such as salmon, and it is not a major source of iron.
Can babies eat sea bass?
Yes, from around 6 months, cooked until opaque and flaky, with every bone removed. Black sea bass is on the FDA's low-mercury 'Best choices' list. Chilean sea bass is a 'Good choice', so our suggestion is to serve it now and then, and lean on 'Best choices' such as salmon, cod and pollock the rest of the time.
Which sea bass is lowest in mercury?
On the FDA list, black sea bass is a 'Best choice'. Chilean sea bass (Patagonian toothfish) and ocean striped bass are 'Good choices'. Other kinds, such as European sea bass (sold as branzino: see our branzino page), aren't named on the FDA list. If you can't tell which kind it is, our suggestion is to treat it as an occasional fish, like a 'Good choice'. Shark, swordfish and marlin are the ones both US and UK advice say never to give children.
Is sea bass safe when we travel?
In tropical areas, the CDC lists sea bass among the reef fish that can carry ciguatera, a toxin that cooking doesn't destroy. When you're traveling in those areas, choose a different fish for your child. Symptoms such as nausea, vomiting, diarrhea or tummy pain usually start 3 to 6 hours after eating, but can start up to 30 hours later; the CDC says to seek medical care if they start after eating fish.
If your baby refuses sea bass
- 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 sea bass
- Keep raw sea bass in the fridge and cook it within 2 days, or freeze it. Thaw frozen sea bass in the fridge overnight.
- Cooked sea bass 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 them 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.
