What is Swai Fish?

Swai is a fish with white flesh and a neutral, mild flavor. The flesh has a firm texture, but it is still tender and moist and is quite flaky once cooked. Because of its neutral taste, it takes on other flavors rather easily.

This fish can be found in Asia and is farmed in Vietnam extensively. They are then exported to North America. It is considered a healthy dietary option as it provides you with lean protein and healthy fats.

It is rich in omega-3 fatty acids which is necessary for healthy skin, hair, and nails. This fat is also needed for a healthy heart and circulation. A 4-ounce serving of swai will give you the following:

  • 70 calories
  • 15 grams of protein
  • 1.5 grams of fat
  • 11miligrams of omega-3 fats
  • 45 grams of cholesterol
  • 0 grams of carbohydrates

Because of its protein and fat content, as well as the fact that it has no carbs, it is a good option for people trying to lose weight. There are lots of healthy swai fish recipes that are keto-friendly and suitable for low-carb diets.

Swai is also known as ‘basa’. If you cannot find swai, you can use tilapia as a substitute. Tra, Vietnamese catfish, panga, and cream dory are other species that are similar to swai and can be used instead.

Swai vs. Tilapia

We talked a little about how tilapia is a good substitute for swai, but here’s how they are different.

Tilapia is a Cichlid fish species, originating from Africa, while Swai is a South-East Asian variant of catfish. Although you can use tilapia, catfish is more similar to swai. 

In terms of flavor, we have to say that swai has a more pleasant taste and absorbs more of the sauces and spices. On the other hand, tilapia is much blander
