what is swai fish

Swai fish is a white-fleshed, mild-flavored freshwater fish that is native to Southeast Asia, particularly the Mekong Lake of China, but is mostly farmed in Vietnam. It is also known by other names such as Asian catfish, basa, iridescent shark, and striped pangasius. Swai fish is affordable and has a delicate texture that melts in your mouth, making it a popular substitute for more expensive fish like haddock. However, there are concerns surrounding its production on crowded fish farms, where it can contain high levels of antibiotics and chemicals. Swai fish is sometimes intentionally or accidentally mislabeled as another type of fish, such as perch, grouper, or sole, and restaurants may not identify the type of fish in some dishes. Swai fish is not as nutritious as fatty fish, but it is still a good source of protein and a few key nutrients. While it is generally safe to eat if thoroughly heated, it is recommended to buy brands that have eco-certification from an independent group, such as the Aquaculture Stewardship Council.
