As the saying goes, things are more valuable when they are rare, and gold production is small. Gold is sold by the gram, and the same is true for saury. The number of swordfish is decreasing. The reason why the fish is expensive is not only because of its small quantity, but also because of its extremely high nutritional value, which leads to the high price of swordfish. Next, let’s take a look at why saury is so expensive.

First, the number of saury is small

Saury is a migratory fish. Together with pufferfish and anchovy, it is known as one of the three delicacies of the Yangtze River in China. Its meat is tender and delicious. It has the reputation of being the best fresh food in the world. When the fish gradually tapers from head to tail, the abdomen is rounded and the upper jaw is long, exceeding the base of the pectoral fin. The pectoral fin rays are slender with 6 long filaments. The anal fin is long and connected to the caudal fin. The caudal fin is short and small, and the anal fin has 80 soft rays. The body length can reach 26 centimeters, the body is long, the sides are flat, and it tapers backwards into a sickle shape, hence its name. Swordfish are generally 18 to 25 centimeters long and weigh 10 to 20 grams. A report from the Freshwater Fisheries Research Center of the Chinese Academy of Fisheries Sciences shows that the output of saury along the Yangtze River was 3,750 tons in 1973, about 370 tons in 1983, and less than 100 tons in 2002. Up to now, the output of saury has been lower. Fishermen can only catch two small fish in half a day out of the boat. If they are unlucky, they won't even catch the fishy fish. Historically, saury was very famous, but now the number of saury coins is getting less and less.

2. Nutritional value of saury

Saury is expensive and popular in the market because of its rich nutritional value, such as EPA and DHA, which can lower blood cholesterol and triglycerides. , and lower blood pressure and avoid blood clots, which is beneficial to people with high blood pressure or coronary artery sclerosis. In addition, swordfish is also rich in vitamin B, which can delay aging. The dark fleshy part of the saury's back contains a lot of vitamin B12, which prevents anemia. The fish is also rich in protein, as well as unsaturated fatty acids such as eicosapentaenoic acid and docosahexaenoic acid, EPA, which are indispensable to the human body. DHA has the effect of inhibiting hypertension, myocardial infarction, and arteriosclerosis. There is a reason why swordfish is expensive. Not only is it small in quantity, but it also has extremely high nutritional value.
