Where are squid distributed? A list of the main producing areas
Squid generally refers to the common squid, an animal of the phylum Mollusca, class Cephalopoda, order Teuthida, suborder Oegopsina. Its body is slender and long-conical, with over a dozen tentacles, two of which are longer. The tips of the tentacles have suckers, and inside the suckers are horny toothed rings. When hunting food, it uses its tentacles to entangle and swallow it. It likes to gather in groups, especially during the spring and summer mating and spawning season. Now let's take a look at the distribution of squid producing areas!
The distribution of squid producing areas
Squid producing areas are distributed in the tropical and temperate seas between 40° north and south latitude. The world's main squid fishing grounds are in the northern South China Sea, the Gulf of Siam, Kyushu in Japan, the central Philippine Islands, western Western Europe, and the eastern and western waters of the United States. The fishing grounds are mostly located around islands and reefs where the water is clear and the current is slow, the salinity is relatively high, the bottom is coarse and hard, the seabed has hollows, and coastal water systems meet warm current water systems.
Countries that catch squid
The main countries catching squid are Thailand, China, the Philippines and Vietnam. Their total catch accounts for about 60% of the world's total catch of the family Loliginidae, and the most important target species is the common squid. Spain, Italy and the United States also catch large numbers of common squid. Trawls, purse seines and set nets are the main fishing gear. Protecting common squid eggs is an important measure for increasing resources. In addition, the common squid is also an ideal target for stock enhancement through release.
The nutritional value of squid
1. Squid is rich in calcium, phosphorus and iron, which helps bone development and blood production, and can effectively treat anemia.
2. In addition to being rich in protein and amino acids needed by the human body, squid also contains a large amount of taurine, which can inhibit cholesterol levels in the blood, relieve fatigue, restore vision, and improve liver function.
3. The polypeptides and selenium it contains have antiviral and anti-radiation effects.
4. Professor Wang Cunxin of the Institute of Oceanology, Chinese Academy of Sciences, said that cholesterol is divided into low-density and high-density types, and cholesterol is mainly high-density, which is beneficial and harmless to the human body. The structure of fat in squid is clearly different from that of fat in livestock and poultry.
5. It contains protein, omega-3 fatty acids, copper, zinc, B vitamins and iodine. B vitamins help relieve migraines, phosphorus helps calcium absorption, and 100 grams of squid contains only 70 kcal of energy.
Note: Although squid is delicious, not everyone is suitable to eat it. People with cardiovascular diseases such as hyperlipidemia, hypercholesterolemia and arteriosclerosis, as well as patients with liver disease, should eat it with caution, and people with weak and cold spleen and stomach should also eat less. Squid is a "stimulating food", and people with diseases such as eczema and urticaria should avoid eating it.
