Common Types in Hong Kong
The Consumer Council lists common types including totoaba-type maw (鰵魚膠), white maw (白花膠), yellow maw (黃花膠), zha maw (扎膠) and cod maw (鱈魚膠). Totoaba-type and white maw are the most prized, while cod maw suits a smaller budget.
Is Fish Maw the Same as 魚肚?
The Consumer Council explains that both fish maw and 魚肚 are swim bladders. Some 魚肚 is fried, dried and puffed, whereas fish maw shrinks as it dehydrates, so it usually comes from large fish and is richer in gelatin, which is why it is pricier.
How to Choose (Consumer Council Tips)
- 📏 Shape: large and thick; if two pieces have the same head count, choose the thicker one.
- 🎨 Colour: white or pale yellow, glossy, translucent, no blood vessels, clear ripple pattern.
- ⚖️ Head count: pieces per catty (600 g); fewer heads means larger pieces.
- ♂️ Male maw (花膠公) generally has better texture than female (花膠乸) and is usually pricier, though not all can be told apart by appearance.
Nutrition and Traditional View
Consumer Council: fish maw is rich in protein and is traditionally said to nourish yin, moisten the lungs, tonify the kidneys and benefit the skin, which is why it is popular with women. We have not found an official Hong Kong Chinese medicine database entry for fish maw, so we do not add further claims.
