This billion-dollar part of a Vietnamese fish is sought after by the world, Japan is like a “gift”, fishermen can only catch 1 fish and have enough to eat for a lifetime.
Vietnam has a long coastline with a wide variety of seafood resources. In particular, not many people know that our country possesses a rare fish, which is sought after by other countries and is likened to a “sea gold nugget” because of its extremely high nutritional and medical value.
That precious fish is the goldfish. In Vietnam, it is common to catch yellow shark with a weight ranging from 2 to 135kg, which is hunted by many traders with prices up to billions of dong depending on weight. This fish is scatteredly distributed from the North to the South but is now almost extinct. However, they have not been included in the red book because they can still be caught, so the yellow catfish becomes a rare fish. The rarity and value of this fish has made them worth billions of dong.
Otolithoides biauritus (scientific name is Otolithoides biauritus), also known as yellow fin sardines, is the largest fish in the sardines family, belonging to the order of sea bass (family Sciaenidae). This fish usually only lives in a few countries such as India, Indonesia, Sri Lanka, China, and Vietnam.
The main habitat is the sea, but in the spawning season (usually from January to April every year and from 9 to 10 of the lunar calendar), they swim towards brackish estuaries to lay eggs.
When the eggs hatch, the fry will swim upstream to fresh water to live within the first 1 to 2 years (it was about 10kg at that time), the size can reach 160cm, weigh over 120kg, the maximum length achievable is 160cm.
Goldfish are very difficult to grow in an artificial environment, so keeping this fish as an ornamental or conservation is extremely difficult. Previously, the Red River estuary was the breeding center of yellow scorpion. In the past, people used to go fishing in this area and every day, about 20-30 tons of yellow scorpion were collected. But because fishermen come every season, they gather to catch schools of yellow catfish, making the number of species increasingly exhausted.
Overfishing and fishing, along with difficulties in developing artificial environments, have made them nearly extinct.
Goldfish with sharp snout, wide mouth, saffron color, lower jaw extending to the bottom behind the eye socket, strong teeth, long dorsal fin. Their lower half is silvery-white with a slight pinkish tinge. Depending on the environment they live in, the head and back are gray or blue. When the yellow fish dies, the whole body of the fish will gradually change color from light yellow to dark yellow.
Yellow fish meat is a dish that is very popular with the people of Hong Kong, China and Japan. The unique dishes made from yellow fish meat are in the top 10 most favorite dishes of Hong Kong people, among the most expensive in the world. The Chinese believe that eating yellow fish will have good luck and prosper in business. In Japan, this type of fish is likened to the heavens bestowed on it because of its economic value and rarity.
However, the special thing that makes the expensive price of this fish is not in the nutritional value of the fish meat, but in the fish’s bladder. The dried fish ball is a food with high nutritional value, helping to nourish the liver and kidneys on par with ginseng. In the bubble of the yellow catfish, every 500 grams contains 442 grams of protein. Therefore, eating it helps to replenish the legs, activate the blood and yang, supplement the body with weakness, anemia, especially for pregnant women or after giving birth.
The price of fresh yellow anchovy bubbles costs 45,000 – 55,000 USD/kg, equivalent to 1-1.25 billion VND/kg depending on the length of the ball, fish weighing 40 – 50kg, the ball will reach about 1kg fresh.
The goldfish bubble is the most valuable part of this fish, which can be used as a self-dissolving thread.
Another use of the golden fish bubble is to make a self-dissolving thread in medicine. This thread does not cause tissue damage, minimizing the risk of infection. Therefore, using bubble fish to make self-dissipating thread is extremely useful and highly sought after by developed countries.
However, in order to study, model the natural ecology and conserve the yellow shark, it is necessary to minimize overexploitation and trade in products from this fish in the market.
