Can Babies Eat Capelin? How to Cook and Serve

Capelin is a small forage fish, similar in size to a smelt or a large anchovy, and like other little fish it is low in mercury and rich in omega-3s, B12, and calcium. Cook it through, take care with the fine bones, and it makes a soft, nutrient-dense early fish. Its salted roe (masago) is a different, very salty product and not a baby portion.

Capelin is a slim, silvery fish from cold northern waters, eaten whole in many places and often dried, grilled, or fried. Because it is small and short-lived, it barely accumulates mercury, which puts it in the same friendly category as sardines and anchovies for babies. You may also know capelin through masago, the tiny orange roe on sushi, but that is heavily salted and is not the same as offering the cooked fish. The fish itself, cooked and boned, is a gentle way to bring oily fish into your baby's week.

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

6 to 9 monthsCook capelin fully, remove the head and guts, then flake the flesh and carefully pick out the fine bones. Mash and mix into potato, sweet potato, or avocado for a smooth, scoopable meal.

9 to 12 monthsOffer soft, boned flakes of cooked capelin as finger food, or stir mashed fish through grains and vegetables. Keep it plainly cooked and unsalted.

12 months+Flaked capelin works through pasta, rice, or on toast fingers. Continue to check for bones and skip the salted, dried, and roe versions in favor of fresh fish.

Is capelin safe? Choking & prep

Capelin is a small forage fish, so it is low in mercury and is the kind of fish health authorities encourage rather than limit for young children.¹ The main jobs at home are cooking and bones. Cook capelin fully, then flake the flesh and run your fingers through it to find and remove the fine bones before serving, since small fish bones are sharp and a choking and injury risk for a baby.² Watch salt too: capelin is often sold dried or smoked, and capelin roe (masago) is very salty, none of which suit babies under 1, who should have less than 1 gram of salt a day.² Stick to plainly cooked fresh or frozen fish. Fish is a common allergen, so introduce a small amount on its own the first time and watch for any reaction.³

Nutrition

Capelin delivers omega-3 fats (DHA) for brain and eye development, along with protein, vitamin B12, iodine, selenium, and calcium, especially when the soft bones are well mashed in. As a naturally oily fish it is an efficient way to get those brain-supporting fats, and official advice to cap oily fish at a few portions a week is easy to stay inside with a baby.¹

Storage & freezing

Fresh capelin is perishable, so cook it the day you buy it or keep it frozen until you need it. Cooked capelin keeps in the fridge for a day or two. Dried, smoked, or roe products are salty pantry items rather than everyday baby food, so treat them differently and, for babies, favor plainly cooked fresh or frozen fish.

Introducing this allergen

Common questions

Is capelin high in mercury?

No. Capelin is a small forage fish that lives a short life low in the food chain, so it carries very little mercury, much like sardines and anchovies. That makes it a good fish to offer regularly.

Is masago (capelin roe) the same as the fish?

No. Masago is capelin's roe and it is heavily salted, which is not suitable for babies. Offer the plainly cooked fish instead, and save salty roe products for much later.

How do I handle the bones?

Cook the fish through, then flake it and run your fingertips through the flesh to find and remove the fine bones. Small fish bones are sharp, so this step matters before every serving.
