Fish is a highly nutritious food, and when it comes to preparation, the fish meat is usually the star of the dish. Often, the remaining parts of the fish are discarded, but there’s one particular part that is gaining attention among consumers and commanding a high price: fish bladder.
The Surprising Health Benefits of Fish Bladder
Fish bladder resembles a long airbag and its main function is to help fish regulate their buoyancy and balance in the water. Interestingly, this organ is a rich source of protein and contains beneficial nutrients such as collagen, calcium, zinc, and various vitamins.
Also known as ‘hua jiao’ or ‘piao jiao’ in traditional Chinese medicine, fish bladder is believed to have therapeutic properties. It is considered one of the eight precious foods that can nourish the yin, tonify the blood, strengthen the kidneys, and enhance essence. For those suffering from general debility, dishes made from fish bladder are thought to be effective in restoring energy and health.
Fish bladder is particularly rich in collagen, a crucial protein that accounts for 70% of our skin composition. Collagen plays a vital role in skin regeneration and elasticity, helping to maintain soft, supple skin and preventing the signs of aging. Additionally, collagen contributes to the health of hair, nails, and joint cartilage. According to a 2018 study by Harvard University, collagen from fish bladder can stimulate the production of synovial fluid in joints, resulting in smoother joint function and potentially reducing the risk of joint degeneration in older adults.
Fish bladder also contains essential amino acids such as hydroxyproline, proline, and glycine. Glycine, in particular, has gastroprotective properties and aids in digestion and nutrient absorption. A 2021 study by the University of Tokyo found that glycine derived from fish bladder promotes recovery from gastric injuries and reduces the risk of stomach ulcers.
Additionally, fish bladder contains an amino acid called arginine, which plays a crucial role in wound healing. Arginine helps the body produce nitric oxide, a molecule that enhances blood flow, ensuring efficient delivery of oxygen and nutrients to injured areas. This, in turn, accelerates the healing process.
From Discarded By-Product to Delicacy
In many Asian countries, such as China and Japan, fish bladder is considered a prized ingredient in cuisine. It is commonly used to prepare nutritious soups and broths.
The price of fish bladder varies depending on the type of fish. For example, while catfish bladder is relatively inexpensive and easily accessible, the bladder from more expensive fish species can command a higher price. In some cases, the bladder of certain fish, like the barracuda, can sell for a premium price of 3-5 million VND per kilogram.
The process of preparing fish bladder for the market is labor-intensive and requires a great deal of skill and attention to detail. According to producers, the complex procedure involves removing the fat, carefully cleaning and turning the bladder inside out, salting it, and then drying it. Each step must be executed meticulously to ensure the delicate bladder remains intact and undamaged during the drying process.
On average, it takes 5-7 kilograms of fresh fish bladder to produce just one kilogram of the dried product. Traditional sun-drying methods produce higher-quality bladder, but prolonged rainy seasons and high humidity can ruin entire batches. This is one of the reasons why fish bladder is becoming increasingly expensive. During the rainy season, many small producers may not have any bladder to sell. Larger producers often use industrial dryers to ensure a consistent supply for the market and even for export.
