Swai fish is one of those seafood options you’ve probably eaten without even realizing it. It often shows up in restaurants as a budget-friendly white fish and appears in grocery stores as frozen fillets. Mild, flaky, and easy to cook, swai has become popular worldwide but it also raises a lot of questions. Is swai fish healthy? Is it safe to eat? How does it compare to other white fish?

Let’s break it all down in a simple, honest, and practical way.

What Is Swai Fish?

Swai fish is a freshwater fish native to Southeast Asia, especially Vietnam. It belongs to the catfish family and is sometimes called pangasius or iridescent shark (even though it’s not a shark at all).

Because swai grows quickly and is inexpensive to farm, it’s widely exported and often used as a substitute for more expensive fish like cod, haddock, or sole.

Why Is Swai Fish So Popular?

Swai didn’t become popular by accident. It checks several boxes for consumers and food businesses alike.

Affordable and Accessible

Compared to many ocean fish, swai is much cheaper. That makes it attractive for restaurants, cafeterias, and households trying to save money.

Mild Flavor

Swai has a neutral taste, which means it easily absorbs marinades, spices, and sauces. Even people who “don’t like fish” often enjoy swai.

Soft, Flaky Texture

Its tender flesh works well in frying, baking, grilling, or air-frying.

Nutritional Profile of Swai Fish

Swai fish is not the most nutrient-dense fish, but it still offers some benefits.

Yes—if sourced responsibly.

Look for:
