"articleBody": "Basa \u2014 Pangasius hypophthalmus \u2014 is one of the Mekong Delta's most important fish. Most people know it as a white fillet. But the byproduct story is where it gets interesting.I've sourced basa byproducts \u2014 particularly the swim bladder (fish maw) and skin \u2014 for buyers in Hong Kong, China and Japan. The market is real, demand is growing, and Vietnam is one of the few places where volume, quality and price can align.\n\n\n\nBasa Bladder (Fish Maw) \u2014 The Luxury Ingredient\n\n\n\nBasa swim bladder \u2014 known in the trade as fish maw or bong b\u00f3ng c\u00e1 \u2014 is a premium ingredient in Chinese, Hong Kong and Japanese cuisine. It's prized for its texture, high collagen content, and traditional health associations. The market is driven by end consumers who specifically seek it for premium cooking and traditional medicine applications.\n\n\n\nFor detailed product specifications, grades and packaging options, see the basa bladder product page.\n\n\n\nGrades Buyers Source\n\n\n\n\nGrade A (large, intact): Highest value \u2014 restaurant and gift market in HK/China; price premium significant\n\n\n\nGrade B (medium): Standard commercial grade \u2014 retail packs, food service\n\n\n\nGrade C (small/mixed): Industrial use \u2014 collagen extraction, supplement manufacturing\n\n\n\n\nThe Mekong Delta produces large volumes of basa bladder as a natural byproduct of fillet processing. This is what makes Vietnam competitive: bladder is extracted during primary processing, meaning supply is tied to fillet production volumes rather than a separate catch. For buyers, this translates to consistent availability.\n\n\n\nBasa Fish Skin
