Can Babies Eat Threadfin? How to Cook and Serve

Threadfin, called ma yau in many Asian kitchens, is a soft, mild fish that is low in mercury and has relatively few bones, which is why it is a classic first fish for babies across Southeast Asia. Cook it fully and flake it soft.

Threadfin is a beloved everyday fish in Singapore, Malaysia, and much of Asia, where it often goes by ma yau. Parents reach for it as a baby's first fish for good reason: the flesh is soft and mild, it is low in mercury, and it has fewer of the fiddly bones that make some fish stressful. Threadfin bream, a related fish sold in the same markets, is also low in mercury and handled the same way.

Prep School: how to prepare threadfin for baby-led weaning (BLW) and purées

🍴 Baby-led weaning

6 monthsSteam a fillet with a slice of ginger to 158°F (70°C) on a food thermometer,⁴ or until it flakes, then mash it soft and load a spoon your baby can grab. Threadfin has relatively few bones, but few is not none, so feel through it first.

9 monthsOffer soft, deboned flakes for your baby to pick up, or mix them into congee or mashed veg shaped to scoop. Keep checking for stray bones.

12 months+Serve steamed threadfin over rice with soft vegetables, chopped small. Skip salted, fried, or heavily sauced versions.

🥄 Purées

6 monthsSteam a fillet with a slice of ginger to 158°F (70°C) on a food thermometer,⁴ or until it flakes, mash it soft, and stir a spoonful into rice porridge or mashed vegetable. Feel through the flesh for bones first.

9 monthsMash a little lumpier, or stir soft flakes into congee or vegetable mash as texture builds. Keep checking for stray bones.

12 months+Flake threadfin into a low salt soup, or spoon it over rice with soft vegetables. Skip salted, fried, or heavily sauced versions.

Is threadfin safe? Choking & prep

Threadfin is a low mercury fish, so it is fine to offer a baby regularly rather than limit.¹ It is prized for having relatively few bones, but few is not none, so still cook it fully, to 158°F (70°C) on a food thermometer,⁴ flake it, and feel through the flesh for any small bones before serving. Fish is a common allergen, so give a small first taste on its own and watch for a reaction over the next couple of hours.² Keep salt low and skip salted or heavily fried versions for babies.

Nutrition

Threadfin gives babies soft, lean protein along with omega-3 fats, vitamin B12, and selenium. Its mild, slightly sweet flavor and tender texture make it one of the easier fish to start with.

Goes well with

Rice · Congee · Steamed spinach · Sweet potato · Carrot (soft) · Ginger (a little)

Storage & freezing

Keep fresh threadfin cold and cook it within a day or two, or freeze it. Cooked, deboned flakes keep sealed in the fridge for about a day. Thaw frozen fillets in the fridge and cook the same day, and do not refreeze once thawed.

Common questions

Why is threadfin a popular first fish?

It is soft, mild, low in mercury, and has relatively few bones, so it is gentle to eat and easier to debone than many fish. That combination makes it a go-to first fish across much of Asia.

Is threadfin the same as threadfin bream?

They are different but related fish sold in the same markets. Both are low in mercury and can be handled the same way for babies: cook fully, debone, and flake soft.

Does threadfin still need deboning?

Yes. It has fewer bones than many fish, not zero, so cook it, flake it, and run your fingers through the flesh to catch any small bones before serving.

Is fish an allergen?

Yes, fish is a common allergen. Offer a small amount of threadfin on its own the first time and watch for a reaction. Early, regular fish is generally encouraged.
