So, let’s discover all about this interesting fish, its benefits, and why it’s become such a talked-about topic in the world of seafood!
Key Takeaways
- Swai fish is a freshwater species native to Southeast Asia, particularly thriving in the Mekong and Chao Phraya rivers.
- It has a mild taste and firm texture, making it a versatile ingredient for various cooking methods, including grilling, baking, frying, and broiling.

What is Swai Fish?
Swai fish is a type of catfish native to the rivers of Southeast Asia, particularly found in countries like Vietnam and Cambodia.
Known scientifically as Pangasianodon hypophthalmus, it’s also referred to by other names such as basa, pangasius, or sometimes incorrectly called Vietnamese catfish.
Unlike its American catfish cousin, swai has a more elongated body and a silver to pale pink color. It’s a freshwater fish that has found a significant place in global aquaculture due to its fast growth rate and adaptability to farming conditions.
Physical Characteristics
Swai fish are notable for their elongated bodies, which can grow up to 4 feet in length and weigh up to 45 kilograms. They have a silver-colored skin and a distinctive whisker-like appearance around their mouths, similar to other catfish.
Their bodies are somewhat flat, which allows them to glide effortlessly through the water. This streamlined shape aids in their navigation of the sometimes fast-flowing rivers where they live.
The skin of swai fish is smooth, lacking the scales found on many other fish species, which contributes to their unique texture when cooked.
Nutritional Profile
Swai fish is appreciated not just for its taste but also for its nutritional benefits. It is a low-calorie source of protein, making it a great option for those looking to maintain or lose weight.
For example, the same serving of salmon packs 24 grams of protein and 1,200–2,400 mg of omega-3 fat, while American catfish contains 15 grams of protein and 100–250 mg of omega-3 fat in 4 ounces (113 grams).
