Can Babies Eat Pike? How to Cook and Serve

Pike is a large, predatory freshwater fish that sits high in the food chain, so it tends to build up more mercury than the small fish babies do best on. It is also notoriously bony. For those two reasons it is not a good early fish. Reach for low-mercury choices like sardines, salmon, or trout instead, and if pike is caught locally, follow your area's fish advisory.

Pike, including northern pike, is a long, toothy freshwater hunter, and that predatory lifestyle is exactly the problem for a baby. Fish that eat other fish concentrate mercury through their food chain, and older, larger predators like pike, walleye, and muskie carry some of the highest mercury levels among common freshwater fish. Many regional health departments put pike on their limit or avoid lists for young children and for people who are pregnant. On top of that, pike is famously full of small Y-shaped bones. None of this makes an occasional bite dangerous, but it does mean pike is not the fish to build a baby's early meals around.

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

6 to 9 monthsDo not start fish with pike. Offer low-mercury options instead: fully cooked, mashed, boneless sardines, salmon, or trout blended into potato or avocado.
9 to 12 monthsKeep building fish around low-mercury choices served as soft, boneless flakes. Save predatory freshwater fish like pike for later, and only in line with local advisories.
12 months+If your family eats locally caught pike, follow your area's fish consumption advisory for young children, cook it through, and debone it meticulously before offering a small amount.

Is pike safe? Choking & prep

Pike is a top freshwater predator, so it accumulates mercury through the fish it eats, and older, larger pike carry the most.1 Too much mercury can affect a baby's developing brain and nervous system, which is why many health authorities advise that young children and people who are pregnant limit or avoid higher-mercury predatory fish like pike and instead choose small, low-mercury fish.2 If your family eats locally caught pike, check your state, provincial, or local fish consumption advisory before offering any to a child, because the safe amount depends on the waters it came from.1 Pike is also very bony, with fine Y-bones that are a real choking and injury risk, so any fish served to a baby must be cooked through and painstakingly deboned. And fish is a common allergen. Given the mercury and the bones together, better first fish exist, and there is no nutritional reason a baby needs pike.

Nutrition

Pike is a lean white fish with protein, B vitamins, and some selenium, but its nutrition is not special enough to outweigh the mercury and bone concerns for a baby. Everything useful in pike is available, with far less risk, from small oily fish like sardines and anchovies or from low-mercury choices like salmon and trout, which also add the omega-3 fats a baby actually benefits from.

Goes well with

Sardines · Salmon · Trout · Mashed potato · Peas

Storage & freezing

If pike does come into the house for the adults, keep it cold and cook it the day you buy or catch it, or freeze it promptly. For a baby, the more useful storage advice is to keep a low-mercury alternative on hand: tinned salmon or sardines, or frozen fillets of trout or white fish, ready to cook, so the easy choice is also the safe one.

Common questions

Can babies eat pike at all?

It is best avoided as an early fish. Pike is a predatory freshwater fish that can be high in mercury and is very bony, so low-mercury fish like sardines, salmon, or trout are far better choices for a baby. If an older child eats locally caught pike, follow your local fish advisory.

Why is mercury such a concern in pike?

Pike eats other fish and lives a long time, so mercury builds up in its body through the food chain. Because a baby's brain and nervous system are still developing, guidance is to choose small, low-mercury fish and limit or avoid high-mercury predators like pike.

What should I serve instead?

Small oily fish like sardines and anchovies, or low-mercury fish like salmon and trout, give a baby the omega-3s and protein you want with far less mercury and, when boned well, less choking risk.
