Quick answer
Babies can eat perch from around 6 months, once they show signs of being ready for solids. Prepare it as shown below.
How to serve perch by age

6 months+
Soft flakes or fish cakes
Bake or poach perch 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 perch 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 perch flaked into rice, pasta or soft tortillas. 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 perch in pasta, rice, soft tacos or homemade fish fingers, 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 perch
- 1
Bake skinless perch fillets at 200°C (390°F) for about 8 to 12 minutes, or poach them, until they're opaque and reach 145°F (63°C) in the thickest part. Small fillets cook quickly, so check early. Don't add salt.
- 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.

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 freshwater and ocean perch. Your baby decides how much to eat.
Common mistakes
Missing bones
Perch fillets can still hide small bones. Feel every flake with your fingers, even in fillets sold as boneless.
Skipping the fish advisory for perch caught by family or friends
The FDA says larger perch caught by family and friends are more likely to have local fish advisories because of mercury or other pollutants. Check the advisory for that water. 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.
Undercooking it
Cook it to 145°F (63°C), until it's opaque and flakes easily. Never offer raw fish such as sushi or ceviche.
Relying on battered or fried fish
Perch is often served battered and fried. Baked, steamed or poached fish is a healthier choice than fried, and batter adds fat. Make your own baked fish fingers instead.
Where US and UK guidance differ on perch
United States(AAP and CDC)Your setting
The FDA lists freshwater and ocean perch as low-mercury 'Best choices'. For ages 1–3, a serving is about 1 oz, twice a week. Rockfish is listed separately, as a 'Good choice', so check the label. For perch caught by family or friends, check local fish advisories first.
United Kingdom(NHS)Your setting
The NHS doesn't single out perch, and it isn't on the NHS oily fish list, 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 perch be a choking hazard for babies?
Cooked, flaked perch is a low choking risk, but the CDC lists bones in fish as a choking hazard, and the NHS says to remove bones from fish for babies. Check every flake with your fingers before serving. Always cook perch fully, and never offer raw or undercooked fish.
Can babies be allergic to perch?
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 perch, talk to your pediatrician before offering other fish: people allergic to one type of fish often react to other types (NHS).
Is perch healthy for babies?
A lean source of protein, with vitamin B12: FoodData Central lists about 25 g of protein and 2.2 µg of vitamin B12 per 100 g of cooked perch (mixed species), with little fat (about 1.2 g). It has less omega-3 fat than oily fish such as salmon, and it is not a major source of iron (about 1.2 mg per 100 g).
Can babies eat perch?
Yes, from around 6 months, cooked until opaque and flaky, with every bone removed. The FDA lists freshwater and ocean perch as low-mercury 'Best choices'.
Is perch high in mercury?
No. The FDA lists freshwater and ocean perch as low-mercury 'Best choices'. Perch caught by family or friends is different, because the FDA says larger perch from local waters are more likely to have fish advisories. Check the advisory for that lake or river before you serve it.
Can I use frozen perch?
Yes. Frozen perch 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 perch?
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. The NHS doesn't set a limit for perch. Its limits are for oily fish, and children under 16 shouldn't have shark, swordfish or marlin.
If your baby refuses perch
- 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 perch
- Keep raw perch in the fridge and cook it within 2 days, or freeze it. Thaw frozen perch in the fridge overnight.
- Cooked perch 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.
Last offered today. Once perch is in your baby's diet, keep offering it regularly.
