Can you eat rockfish while pregnant?
In moderationYes, up to one serving a week when it is cooked through. The FDA puts rockfish in its Good Choices group, meaning its mercury level is moderate rather than low.
Why
Rockfish sits in the FDA's Good Choices category on its advice about eating fish, which translates to one 4 ounce serving per week during pregnancy. The limit is about mercury, which accumulates in longer-lived fish and can affect a baby's developing brain and nervous system. Within that limit rockfish is genuinely good for you: the NHS recommends two portions of fish a week for the omega-3 fats, protein and iodine that support fetal development. Cook it until the flesh is opaque and flakes easily, since raw or undercooked fish is a Listeria and parasite risk.
Safer alternatives
- Cod or haddock fillet, a Best Choice you can eat twice a week
- Pacific or Atlantic salmon
- Tilapia fillets
- Canned light skipjack tuna
- Pollock, including fish fingers and fish sticks

Frequently asked questions
How much rockfish can I eat per week while pregnant?
One serving of about 4 ounces, which is roughly the size of your palm. That is the FDA's Good Choices allowance. If rockfish is your fish for the week, fill your second portion with a Best Choice such as salmon or cod.
Is the rockfish in fish and chips or fish tacos safe?
Yes, battered or grilled rockfish is cooked right through, which removes any Listeria or parasite concern. The mercury limit of one serving a week still applies. Ceviche or crudo made with raw rockfish is the version to skip.
Is rockfish the same as red snapper?
No, though West Coast menus often call rockfish snapper. True red snapper is also a Good Choices fish at one serving a week, so the practical advice is identical either way. Both should be cooked until opaque and flaky.
