The source ranks the leading varieties as Golden Coin Croaker fish maw (yellow-lipped fish), white fish maw (large white-flower fish), yellow sturgeon fish maw (sturgeon), yellow croaker fish maw (large yellow croaker), croaker fish maw (large croaker), and Men-shan eel fish maw (large Men-shan eel), with Golden Coin Croaker described as the 'king of fish maw.'
Golden Coin Croaker fish maw is described as the 'king of fish maw.' It is extremely rare and generally kept as a collectible; the source quotes prices above several hundred thousand per catty but gives no currency or valuation date. It says yellow-lipped fish remain in deep-sea caves, do not take bait and are difficult to catch because of their scarcity. The source also records historical claims that this fish maw was 'life-saving' and used to stop bleeding and replenish blood. These are traditional claims, not medical advice; its stated collectible value is far greater than its value as food.
Fish maw is presented not only as a banquet delicacy but also as a traditional nourishing and medicinal ingredient. That description reflects traditional use, not established medical efficacy.
How to select high-quality fish maw?
Many people would not choose fish maw, thinking that as long as it is large enough, or as long as it is expensive or thick, it is fine. In fact, these ideas are all wrong. The quality of fish maw should be understood from a comprehensive perspective.
After stewing, high-quality fish maw should have no fishy smell, sliminess or disintegration; it should be smooth yet pleasantly firm. The source says ordinary fish maw is often used for soup, while better grades can be served as dishes. To select high-quality fish maw, consider the following
factors:
1. Colour
Look for a clean texture without prominent blood vessels or clots, together with a translucent, pale-yellow appearance. Genuine fish maw is not uniformly coloured, completely white or crystal clear. Natural patterns and uneven amber tones may indicate that it has not been bleached. The source warns that some sellers bleach fish maw for a more uniform appearance, altering its natural condition; original-colour pieces may still show blood traces.
2. Size and Thickness
Within the same variety, larger pieces with a thicker fish-maw body are generally graded more highly; the source says the largest can reach one catty per piece. The trade saying, "ten catties of fish yield one liang of fish maw," is used to illustrate that a piece weighing several liang may have come from a fish weighing several tens of catties.
3. Dryness
The drier the fish maw, the better. When selecting fish maw, you can hold it up under a light. If the fish maw appears semi-transparent, it is of better quality. Fish maw with high humidity looks gray and dull, and some fish maw may not be fully dried inside when drying; generally, the edges are transparent, while the center is cloudy, which is called 'flower heart' and should be avoided. Over time, the flower heart part may become moldy, and after soaking, it will emit a foul smell and is not edible.
4. Trade Classification: 'Male' and 'Female' Fish Maw
The trade classifies some fish maw as 'male' or 'female.' Using broad-belly fish maw as an example, the 'male' type is often saddle-shaped, thicker in the centre and thinner at the sides, with V-shaped markings. Firm, thick, dry, golden-yellow and translucent pieces are preferred, and they remain firm and chewy after cooking. The 'female' type is usually rounder and flatter, like corrugated sheeting, with horizontal or wavy markings. It is thinner, softens or dissolves more readily when simmered, and is generally priced below the 'male' type.
5. Smell
High-quality fish maw has no fishy or unpleasant smell. After stewing, it still has no fishy odor, and the best quality is smooth and tender without being slippery.
6. Age
The source associates darker colour with greater age. It claims that ageing reduces the concentration of gelatin, making nutrients easier to absorb and the product more nourishing; this is a traditional claim, not an established health effect. Aged fish maw is described as yellow to dark or golden yellow and less fishy, while newer fish maw is whiter and has a stronger fishy smell.
7. Place of Origin
Fish maw is produced in Myanmar, Brazil, New Zealand and India, among other places. The source says fish maw from waters off Guangdong commands the highest prices, especially Golden Coin Croaker fish maw from the Humen area. It attributes this quality to the brackish-water environment and its natural mineral content; this is the source's market explanation rather than an independently verified origin premium.
8. Look at the texture and quality
Some fish maws are coarse, while others are tender. Pick up the fish maw and look at it in a well-lit place to see the lines and texture inside, which helps determine the quality. Truly high-quality fish maw will not fall apart no matter how long it is stewed.
There are also some other factors that jointly determine the quality of fish maw. In summary, natural, pure, wild, and aged fish maw is good fish maw. The above 8 points are the most basic ways to judge it.
