The best seafood for protein includes tuna, salmon, sardines, cod, shrimp, and scallops, which pack plenty of protein with moderate calories.
Seafood makes it easier to raise protein intake without loading every plate with poultry or red meat. Many fish and shellfish give high protein per bite, plus omega‑3 fats, B vitamins, and minerals linked with heart and brain health.
This guide walks through high protein seafood options, how different choices compare, and how to fit them into simple meals. You will also see how portion sizes, cooking methods, and mercury levels change which fish belongs on your plate each week.
High Protein Seafood At A Glance
Start with a quick look at how common options stack up. Values below use typical cooked portions drawn from large nutrient databases and government charts, so numbers may vary slightly by brand and cooking method.
| Seafood (Cooked) | Protein Per 100 g | Approx Calories Per 100 g |
|---|---|---|
| Tuna | 26 g | 130 kcal |
| Salmon | 22 g | 200 kcal |
| Cod | 20 g | 90 kcal |
| Shrimp | 24 g | 120 kcal |
| Scallops | 24 g | 140 kcal |
| Sardines | 23 g | 185 kcal |
| Mussels | 18 g | 170 kcal |
| Crab | 19 g | 100 kcal |
Protein numbers above reflect cooked edible portions, not raw weight. Government resources such as FDA seafood nutrition posters and USDA FoodData Central list similar values, which gives confidence that these are realistic ballpark figures.
Why Seafood Is A Strong Protein Choice
Protein from seafood supplies all the amino acids your body needs for muscle repair, immune function, and daily maintenance. Many fish deliver that protein with less saturated fat than fatty cuts of beef or pork, which can help people who watch heart health or cholesterol.
Fish and shellfish also bring long chain omega‑3 fats such as EPA and DHA, nutrients linked with heart, brain, and eye health. Those fats appear in higher amounts in oily fish like salmon, sardines, herring, and mackerel.
On top of that, seafood contributes iodine, selenium, vitamin D, vitamin B12, and other micronutrients that are harder to find in land animal protein. When you choose high protein seafood a few times per week, you cover several nutrition bases at once.
Best Seafood For Protein Foods Ranked
Ranking seafood for protein means looking at protein density, calorie load, fat type, mercury level, cost, and how easy it is to cook. No single fish wins every category, so the goal is to pick a short list that fits your routine.
Tuna: Protein King With Mercury Tradeoffs
Cooked tuna sits near the top for protein per 100 grams, often landing around 26 grams with modest fat and calories. That makes it especially handy for sandwiches, salads, and grain bowls.
The catch is mercury. Larger tuna species tend to carry more mercury, which matters for people who are pregnant, might become pregnant, or feed young children. The joint FDA and EPA fish advice recommends limiting high mercury fish and choosing light canned tuna more often than albacore for these groups.
Salmon: High Protein With Omega‑3 Fat Bonus
Cooked Atlantic salmon lands around 22 grams of protein per 100 grams, with more fat than extra lean white fish but a large share in the form of omega‑3 fats. It works well baked, grilled, or pan seared, and leftovers flake nicely into salads or tacos.
Cod And Other Lean White Fish
Cod, pollock, haddock, and similar white fish bring around 18 to 21 grams of protein per 100 grams with low fat. Calories often fall near 90 to 110 per 100 grams, which makes these fish stand out for lean weight loss focused plans.
Shrimp, Crab, And Other Shellfish
Shrimp gives roughly 20 to 24 grams of protein per 100 grams cooked, with a low calorie count compared with many meats. Crab, lobster, and similar shellfish sit in the same range. These options work nicely in stir fries, salads, pasta, and rice dishes.
Sardines, Anchovies, And Small Oily Fish
Small oily fish such as sardines and anchovies pack dense protein, calcium from soft bones, and strong omega‑3 fats. Canned sardines often land around 22 to 23 grams of protein per 100 grams along with calcium and vitamin D.
Because these fish sit low on the food chain, they tend to carry less mercury than large predators. That helps them stand out as smart regular choices for people who want both strong protein and healthy fat.
High Protein Seafood By Cooking Method
Cooking method can change how much usable protein you get on the plate. Long, high heat frying can dry out fish and shrink portion size, while gentle baking or steaming keeps moisture and texture.
Grilled Or Baked Fillets
Grilling or baking salmon, cod, trout, or halibut with a light brush of oil keeps added fat modest and preserves protein. Season with salt, pepper, citrus, herbs, or spice blends instead of heavy cream sauces when you want a leaner plate.
Poached, Steamed, Or Air Fried Seafood
Poaching and steaming use little or no added fat and keep delicate fish moist. Air fryers can mimic a fried texture with far less oil when you coat fillets or shrimp in a thin crumb.
Canned Seafood For Quick Protein
Canned tuna, salmon, mackerel, sardines, and anchovies make high protein seafood far easier to eat during a busy week. A standard can of light tuna often gives 20 to 25 grams of protein, and canned salmon sits in a similar range.
Choose options packed in water for the leanest profile, or in olive oil if you prefer more flavor and do not mind extra calories. Rinse off excess oil or sauce if the label lists a lot of sodium.
High Protein Seafood For Different Goals
High protein seafood choices look slightly different for weight loss, muscle building, family meals, or tight grocery budgets. This section shows how to match fish choices to your main goal.
Leaner Choices For Fat Loss
If you track calories closely, lean fish such as cod, pollock, tilapia, and sole give strong protein with fewer calories. Pair them with roasted vegetables and a small portion of whole grains for meals that feel satisfying yet light.
Higher Fat Fish For Heart Health
For people who want more omega‑3 fats, pick salmon, sardines, trout, herring, or mackerel two to three times per week. The EPA and FDA fish and shellfish advice encourages regular fish intake while steering people toward lower mercury choices.
These fish bring slightly more calories per gram than extra lean white fish, yet the extra fat helps heart health when it replaces processed meats or fried snacks.
Budget Friendly Protein Picks
Canned light tuna, canned salmon, sardines, and frozen white fish fillets often cost less per gram of protein than fresh fillets at the seafood counter. Buying in bulk and freezing portions stretches your budget further.
Watch for plain frozen fillets without breading or rich sauces. That way you can season and cook them how you like while keeping calories and sodium under control.
Budget Friendly Seafood Protein Picks
When money feels tight, your most cost effective seafood protein choices usually come from the canned and frozen aisles. Dry goods sections also stock shelf stable pouches that slip into lunches and snacks.
| Seafood Option | Typical Serving Protein | Notes For Shoppers |
|---|---|---|
| Canned Light Tuna | 20–25 g per can | Often lowest price per gram of protein. |
| Canned Salmon | 20–23 g per 100 g | Bones provide calcium; good in patties. |
| Canned Sardines | 22–23 g per 100 g | High omega‑3 fat and calcium. |
| Frozen White Fish Fillets | 18–21 g per 100 g | Buy plain bags, season at home. |
| Frozen Shrimp | 20–24 g per 100 g | Great for stir fries and pasta. |
| Imitation Crab | 7–9 g per 100 g | Lower in protein; check sodium. |
| Fish Sticks | 10–12 g per 100 g | Convenient yet higher in breading and fat. |
Store brands often sell canned and frozen seafood at lower prices than national brands. Check unit prices on shelf labels to see how much protein you get for each dollar spent.
How To Build A High Protein Seafood Meal
Once you have a short list of fish you like, focus on portions and sides. A useful target for many adults is 20 to 30 grams of protein per meal, matched with fiber rich plants and healthy fats.
Simple Meal Ideas
Try grilled salmon with roasted potatoes and green beans, cod baked with tomatoes and olives, shrimp stir fry with mixed vegetables and brown rice, or sardines on whole grain toast with lemon and capers. Each of these plates can deliver that 20 to 30 gram protein range with balanced carbs and fats.
Protein Portions Across The Week
Most guidelines suggest at least two seafood meals per week for general health, with more room for people who enjoy fish and choose lower mercury species. Rotating salmon, white fish, and shellfish keeps flavors fresh while spreading different nutrients through the week.
Safety, Mercury, And Who Should Be Careful
While high protein seafood brings many benefits, a few groups need tighter limits on mercury exposure. People who are pregnant, might become pregnant, or care for young children should favor fish from the lower mercury list and avoid shark, king mackerel, tilefish from the Gulf of Mexico, and bigeye tuna.
Putting Your Seafood Protein Plan Together
The best seafood for protein for you depends on personal taste, budget, cooking confidence, and daily health needs. Build a base of lean white fish, add salmon or other oily fish a couple of times per week, and keep canned tuna or sardines on hand for quick meals.
By paying attention to portion size, mercury guidance, and cooking method, you turn simple fish and shellfish into a reliable protein anchor for your week without getting bored or overspending.
