If you've ever taken a close look at a fillet of Swai, you might wonder—wait, where are the scales? You're not alone.
Swai, also known as Pangasius or iridescent shark catfish, is a freshwater fish that, unlike many of its aquatic counterparts, doesn’t have scales. This might seem odd if you're used to the flaky, silvery scales on fish like tilapia or salmon. But Swai is a type of catfish, a group of fish that naturally lack scales. Instead, Swai has a thick skin that's smooth and durable—kind of like nature’s built-in wetsuit.
If you follow a Kosher diet, the lack of scales is a big red flag. In Jewish dietary law, only fish with both fins and scales are considered Kosher. Since Swai doesn’t have scales, it doesn't make the cut. No matter how tasty or affordable it is, it won’t be showing up on the Kosher-approved list anytime soon.
Because of its sleek body and shark-like dorsal fin, Swai has earned the nickname “iridescent shark.” But rest assured, it's not a shark—it just looks like one, especially in its younger stage when its skin shines with a blue-black sheen and the fins stand out starkly. As they grow older, though, Swai lose that shimmer and take on a matte gray color.
Another unique trait of Swai: it sports barbels—whisker-like sensory organs near its mouth. These little feelers help Swai forage along murky river bottoms. Plus, the nerve-rich dark stripes along its body aren’t just for show; they help the fish sense changes in the water’s environment, making Swai highly adapted for navigating turbid rivers.
| Fish Type | Has Scales? | Kosher? |
|---|---|---|
| Swai (Pangasius) | No | No |
| Tilapia | Yes | Yes |
| Salmon | Yes | Yes |
Despite its shark-like appearance, Swai is mild-mannered under all that skin. It’s omnivorous, feeding on both plants and smaller animals, and it's neither predatory nor high in mercury like actual sharks. That makes it a safe, mild-tasting addition to many dinner tables, especially when grilled or baked with your favorite seasonings.
