Most pregnant women can eat 8–12 oz of low-mercury seafood weekly; limit albacore tuna to 6 oz and avoid high-mercury species.
You came here for a clear answer to “how much seafood can pregnant women have?” Here it is, right up front: in the U.S., the FDA and EPA advise 8–12 ounces a week from low-mercury choices, split across two to three meals. That range covers variety, steady omega-3 intake, and safety from mercury. The sweet spot for most plates is two palm-size servings of cooked fish each week, with one more if you like shrimp or canned light tuna.
How Much Seafood Can Pregnant Women Have? — Safe Range And Limits
The target range is 8–12 ounces (about 225–340 grams) of cooked seafood per week from options that test low in mercury. Think salmon, trout, sardines, anchovies, shrimp, pollock, cod, catfish, tilapia, and canned light tuna. Keep albacore (white) tuna to 6 ounces in the same week. Skip shark, swordfish, king mackerel, and tilefish. These rules come from the FDA/EPA fish advice for pregnancy. You can read the current details on the FDA’s Advice About Eating Fish.
Benefits And Risks At A Glance
Seafood offers DHA and EPA fats that help a baby’s brain and eyes. It also brings protein, iodine, selenium, and vitamin D. The trade-off is mercury, which rises in larger predatory fish. The weekly range balances those two sides: enough seafood for nutrients, while staying away from species known for higher mercury.
Best Choices, Good Choices, And Fish To Avoid
The chart below sorts common picks into simple “eat often,” “eat sometimes,” and “skip” buckets with portion ideas. Use it as your quick planner in the first third of this guide.
Table #1: within first 30%
| Category | Examples | How Often (Pregnancy) |
|---|---|---|
| Best Choices (Low Mercury) | Salmon, Sardines, Trout | 2–3 servings/week |
| Best Choices (Low Mercury) | Shrimp, Pollock, Tilapia | 2–3 servings/week |
| Best Choices (Low Mercury) | Cod, Catfish, Herring | 2–3 servings/week |
| Good Choices | Halibut, Mahi-mahi | 1 serving/week |
| Tuna (Light/Canned) | Skipjack, “Light” Blend | Fits within 8–12 oz/week |
| Tuna (Limit) | Albacore/White, Steaks | ≤6 oz/week |
| Avoid (High Mercury) | Shark, Swordfish | Do not eat |
| Avoid (High Mercury) | King Mackerel, Tilefish | Do not eat |
How Much Seafood During Pregnancy By Week — Portion Math
Start with two 4–6 oz cooked portions. Add a third 4 oz portion if you’re choosing very low-mercury picks like shrimp or salmon. That lands you inside the 8–12 oz range. If one meal is albacore tuna, skip a second tuna meal that week and fill the rest with salmon, trout, or shrimp.
Serving Sizes That Make Sense
Cooked fish shrinks a bit. A 4–6 oz cooked portion looks like your palm (without fingers) or a deck-of-cards-plus. For canned tuna, a typical 5-oz can drained is roughly one serving. For shrimp, 8–12 medium cooked shrimp weigh about 4 oz.
Why The Range, Not One Number?
Different fish carry different mercury levels. Variety spreads risk and keeps meals interesting. Rotating salmon, shrimp, and trout gives steady DHA while staying well below mercury limits.
“how much seafood can pregnant women have?” In Real-World Meals
Let’s put the weekly goal into plates you can cook tonight. The ideas below map to two or three seafood meals that meet the target range, without repeating the same tuna sandwich.
Two-Meal Week (8–10 oz)
- Meal 1: Baked salmon, 5 oz cooked, plus roasted potatoes and greens.
- Meal 2: Shrimp stir-fry, 4–5 oz cooked shrimp, mixed veggies, brown rice.
Three-Meal Week (10–12 oz)
- Meal 1: Trout fillet, 4–5 oz cooked, lemon and herbs.
- Meal 2: Canned light tuna salad on whole-grain, ~4 oz drained.
- Meal 3: Fish tacos with cod, ~4 oz cooked fish, cabbage slaw, salsa.
Mercury And Specific Tuna Rules
“Light” or skipjack tuna sits lower on the food chain and tends to run lower in mercury than albacore. That’s why canned light fits inside the 8–12 oz range, while albacore/white tuna gets a single 6 oz cap for the week. If you eat a tuna steak, count it toward that same 6 oz cap.
What About Sushi, Sashimi, And Smoked Fish?
Raw or undercooked seafood raises the risk of harmful germs. The CDC lays out clear guidance to stick with cooked seafood dishes and to avoid refrigerated smoked fish unless it’s in a cooked recipe. For safety basics, see the CDC’s page on Preventing Listeria Infection. If you love sushi, choose rolls made with cooked shrimp, crab (real or pasteurized imitation), or tempura fish.
Deli Salads And Leftovers
Pre-made deli seafood salads can sit chilled for hours, which isn’t ideal. If you buy them, go fresh, portion what you’ll eat right away, and keep the rest cold. Reheat leftover cooked fish to steaming hot and eat within a day.
Local Catch And Advisories
If you fish or get local catch, check regional advisories. Some lakes and rivers carry higher mercury or other contaminants. Many states post simple “eat/limit/avoid” charts by species. If no advice is posted, pick smaller fish of the same species, trim visible fat, and stick to the lower end of the weekly range.
Allergies, Aversions, And Alternatives
If you don’t eat fish, talk with your clinician about a prenatal plus a DHA source. Algae-based DHA supplements avoid fish proteins and can be an option for those with allergies. Eggs labeled “DHA-enriched” can add a small bump, but they don’t replace fish entirely.
Reading Labels And Restaurant Menus
Canned And Pouched Seafood
Look for the species name. “Light” usually means skipjack or a blend. “White” means albacore. Count servings toward your weekly total using the rules above.
Fish Types On Menus
Ask your server which fish is used in tacos, burgers, or “catch of the day.” If it’s a high-mercury species, pick another dish. If it’s salmon, trout, cod, or shrimp, you’re in the clear.
Second-Trimester Nausea Workarounds
If fish smells turn you off, try cold options like lemon-dill salmon pasta salad, tuna mixed with Greek yogurt, or shrimp cocktail with crackers. For cooking, poach or steam with aromatics; both are gentle on scent.
Budget-Friendly Seafood Picks
Frozen fillets keep quality and often cost less. Canned salmon, sardines, and light tuna are affordable pantry staples with long shelf life. They’re also easy to portion, which helps you hit the weekly range without overdoing it.
How We Built This Guide
This article aligns with U.S. federal guidance for pregnancy. The weekly range, tuna limits, and high-mercury list track the FDA/EPA advisory. Food safety notes mirror CDC advice on cooking temperatures and ready-to-eat items like smoked fish. If you’re outside the U.S., check your national guidance. For instance, the U.K.’s NHS sets different limits on tuna and oily fish.

Smart Swaps And Simple Prep
Fast Cooking Methods
Roast at 400°F (205°C) for 10–12 minutes per inch of thickness. Broil 4–6 minutes for thin fillets. Poach in broth or water until the fish flakes. For shrimp, cook until pink and firm.
Seasoning That Works Every Time
- Lemon, olive oil, salt, pepper.
- Garlic and herbs: dill, parsley, chives.
- Spice blends: chili-lime for tacos, paprika-garlic for roasting.
Common Questions, Answered In One Place
Can I Go Over 12 Ounces If My Choices Are All “Best Choices”?
Stick to the 8–12 oz band. That guardrail bakes in a safety buffer across many meals and sources.
Do Omega-3 Supplements Replace Fish?
They can help you hit DHA targets, but they don’t bring the same mix of protein, iodine, selenium, and vitamin D that seafood offers. Think “supplement,” not “swap.”
What If I Had One Meal Of A High-Mercury Fish?
Don’t panic. Switch the rest of the month to low-mercury picks and stay within the weekly range. Bring it up at your next prenatal visit for tailored advice.
The Short Path To A Safe Plate
Pick two low-mercury fish you like, add one canned option, and rotate. Keep albacore to one serving. Skip the high-mercury list. Choose cooked sushi rolls or fully cooked seafood dishes. That’s the plan.
A Note On Regional Differences
The numbers above reflect U.S. guidance. Countries can set different caps based on local exposure data. If you’re following U.K. rules, for instance, the NHS suggests no more than two oily fish portions weekly and sets a separate tuna cap. If you split time across regions, follow the stricter rule set.
Recap You Can Act On Tonight
- Weekly target: 8–12 oz cooked seafood from low-mercury choices.
- Limit albacore/white tuna to 6 oz; avoid shark, swordfish, king mackerel, tilefish.
- Cook seafood; steer clear of raw fish and refrigerated smoked fish unless cooked into a hot dish.
- Use variety: salmon or trout once, shrimp or cod once, plus canned light tuna if you want it.
