How Many Calories Are In Swai Fish? | Lean White Fish Guide

Swai Calorie Breakdown: Raw, Cooked, And Fried

Swai is a mild white fish from the catfish family, sold as skinless frozen fillets. A typical fillet weighs around 4 ounces (113 grams) before cooking. That raw 4 ounce portion lands near 70 to 80 calories and about 15 to 19 grams of protein based on lab work and retail labels. During cooking water leaves, the fillet shrinks, and calories per bite climb. Frying adds oil and batter, which can send the number way up.

Calories And Protein Per 4 Oz Portion

Preparation	Calories (kcal)	Protein (g)
Raw swai fillet	~70-80	15-19
Baked swai, no added fat	~80-90	17-20
Pan seared swai with light oil spray	~100	17-20
Deep fried swai with breading	~180-200+	16-18
Baked salmon, same 4 oz	~180	20-23
Baked tilapia, same 4 oz	~110	22-24

Deep fry oil and breading can double the calorie hit compared with a plain baked fillet. Oil type matters too, since some oils bring unsaturated fat that lines up with heart health guidance in our heart-friendly oils piece.

Swai Nutrition Profile Beyond Calories

A plain swai fillet gives lean protein with almost no carbs. A 4 ounce raw portion shows about half a gram to 2 grams of fat, zero carbs, and around 50 milligrams of cholesterol in many retail listings.

Protein And Fullness

A 4 ounce raw serving packs roughly 15 to 19 grams of protein. You get that protein for under 100 calories in the baked version, which helps with fullness during a calorie cut.

Fat, Omega-3, And Heart Health

Swai stays lean. Total fat per 4 ounce raw portion often sits under 2 grams, and omega-3 fat shows up in tiny amounts compared with salmon or sardines. Salmon can carry hundreds of milligrams of omega-3 in a similar serving, which is one reason salmon shows up on heart health lists again and again.

Sodium And Cholesterol

Raw swai can sit near 30 to 350 milligrams of sodium per 4 ounces in retail nutrition panels, which shows that packaging brine and added sodium can swing a lot between brands. Cholesterol per 4 ounce raw portion often lands around 45 to 55 milligrams. Seasoning, breading, and sauces can push sodium up fast.

USDA FoodData Central lists these calorie and nutrient ranges, and FDA fish advice uses the same 4 ounce serving size when it talks about seafood portions for adults. USDA FoodData Central and FDA fish advice both base their numbers on lab sampling and nationwide monitoring.

Is Swai A Good Pick For Weight Loss Meals?

Many shoppers pick swai during calorie cuts because it fills the plate without blowing the day’s intake. You get a palm-size baked fillet for under 100 calories, which helps if you’re keeping a tight daily budget. The mild taste takes garlic powder, smoked paprika, lemon zest, chili flakes, Cajun blend, and pico de gallo with tiny calorie cost, so you don’t need rich cream sauce.

Portion Size Math For Meal Planning

The table below shows dinner plates built around baked swai, with rough calorie ranges. These numbers assume light oil spray on veg, no butter on the fish, and no deep fry coating.

Sample Swai Dinner Plates

Meal Build	What’s On The Plate	Total Calories (kcal)
Low calorie plate	4 oz baked swai + steamed broccoli + lemon	~200-220
Balanced plate	4 oz baked swai + roasted squash (1 cup) + 1/2 cup brown rice	~350-380
Taco night	Fried swai strips (3 oz cooked) + 2 corn tortillas + slaw + salsa	~500-550
Meal prep bowl	4 oz pan seared swai + quinoa (1/2 cup cooked) + grilled peppers/onions	~400-420

Lime and salsa add little, while creamy slaw and tortillas raise the total fast.

Safe Intake, Sourcing, And Mercury

Swai is farm raised in Southeast Asia, sold in big frozen bags at a budget price. Farm standards can shift by exporter, so many dietitians suggest picking labels that mention third-party farm certification.

This fish, also sold as pangasius or basa, shows low mercury in U.S. retail testing — about 2 parts per billion in one nationwide sample set. Predators like king mackerel and swordfish can sit over 1 part per million, hundreds of times higher. The FDA fish advice chart groups mild white fish such as catfish in “Best Choices.” That label means 2 to 3 servings per week at 4 ounces per serving for an adult, and that same range is cleared for people who are pregnant or breastfeeding, and for young kids, when they stick with lower-mercury fish. FDA fish advice explains that guidance.

Prep Tips To Keep Calories Low

Bake, Air Fry, Or Pan Sear

Pat thawed fillets dry, mist a thin film of oil, and dust with paprika, garlic powder, pepper, and salt. Bake on a lined sheet pan or air fry in one layer until the flesh flakes with a fork. For pan sear, spray a nonstick skillet or seasoned cast iron, heat until it shimmers, lay the fillet down, and flip once after color forms. These methods sit near the 80 to 100 calorie range per 4 ounce raw weight because there’s no heavy breading bath.

Sauces, Sides, And Smart Extras

Lemon wedges, pico de gallo, fresh herbs, chili crunch made with a teaspoon of oil, roasted veggies, and shredded cabbage slaw with yogurt dressing build flavor without a big calorie bump. Rice, potatoes, and tortillas are fine as long as the scoop is measured.
