What kind of fish is sardine

Sardines are a general term for some edible fishes of the genera Sardinella, Sardinella and Sardinellae, and the family Herringidae, in the order Herpetiformes, class of bony fishes. They are about 15 to 30 cm long, live in dense schools, migrate along the coast, feed on a large amount of plankton, swim quickly, and usually live in the middle and upper layers, but live in deeper sea areas when the surface water temperature is lower in autumn and winter. They are generally caught using light purse seines, drift nets, large drag nets and fixed nets.

Sardines are warm-water fish that live in coastal waters and are not usually found in the open sea or ocean. In autumn and winter, adult fish live in deep waters 70 to 80 meters away. In spring, the water temperature rises along the coast and the fish migrate to the coast for reproduction. After the larvae and young fish become young, they feed and grow along the coast. In summer, they gradually migrate northward with the South China Sea warm current. In autumn, the surface water temperature drops, so they migrate southward. After October, when the fish grow to more than 150 mm, they gradually move to deeper sea areas due to the drop in coastal water temperature.

What is the difference between sardines and saury?

Distinction between families and genus

1. Sardines: Sardines are a general term for certain edible fishes belonging to the animal kingdom, phylum Chordata, subphylum Vertebrata, class Osteichthyes, subclass Actinopterygii, order Herpetiformes, family Herringidae, genera Sardinella, Sardinella and Pseudo-Sardina.

2. Saury: Saury is the only species of fish in the animal kingdom, phylum Chordata, subphylum Vertebrata, class Osteichthyes, subclass Actinopterygii, order Gnathiopicus, suborder Gnathiopicus, family Saurydae, and genus Saury.

Morphological differences

1. Sardines: Sardines are slender silver fish with only one short dorsal fin, no lateral line, a scaleless head, and a body length of about 15 to 30 centimeters. The lower jaw is slightly longer than the upper jaw, the teeth are not obvious, the back is pale and the belly is white, the meat is delicious, and it is mostly used to make canned food.

2. Saury: Saury is thin and round, rod-shaped, with 5-6 small fins behind the dorsal fin and 6-7 free small fins behind the anal fin. There are many protrusions on both sides, but they are not long-rimmed, and the teeth are thin and weak. The back of the body is dark blue, the abdomen is silvery white, the snout and the back of the tail peduncle are slightly yellow, and the body length can reach 35 cm.

Origin difference

1. Sardines: The Far Eastern sardine is distributed in the eastern part of Honshu, Japan, the southwestern Kyushu, the Sea of ​​Japan and the Tsushima Strait. The California sardine is produced in the coastal areas of California and western Canada. The South American sardine is produced in the coastal areas of Chile and Peru in South America. The Australian sardine is produced in Australia and New Zealand. The South African sardine is distributed in the coastal areas of southern Africa, Angola and Namibia. The sardina is distributed in the western India, Pacific and Atlantic seas. The sardina is distributed in the northeastern Atlantic and Mediterranean coasts.

2. Saury: Saury is distributed in the North Pacific, including the Sea of ​​Japan, Alaska, Bering Sea, California, Mexico and other waters. It is located between 67 and 18 degrees north latitude and 137 and 108 degrees east longitude. It prefers a water temperature of 15 to 18 degrees Celsius. It is mainly distributed in the Yellow Sea and the east coast of Shandong in my country.

Nutritional Differences

1. Sardines: Sardines have amazing nutritional value. They are rich in phospholipids, namely OMEGA-3 fatty acids, protein and calcium. This special fatty acid can reduce the production of triglycerides (harmful fatty acids that cause blood clots), and has the magical effect of gradually lowering blood pressure and slowing down the speed of atherosclerosis. At the same time, the phospholipids in sardines have a beneficial effect on the brain development of the fetus.

2. Sanma: Sanma is rich in protein and fatty acids. The protein content is 20.7%. It contains unsaturated fatty acids such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), which are indispensable to the human body. EPA and DHA can inhibit hypertension, myocardial infarction and arteriosclerosis.

Can pregnant women eat sardines?

You can eat it.

For pregnant women, it is actually possible to eat sardines during pregnancy. This is a good choice, mainly because sardines are rich in phospholipids. And the phospholipids in sardines are easily absorbed by us, so sardines are very good for the brain development of the fetus, and sardines can promote gastrointestinal health. At the same time, in addition to phospholipids, sardines also contain a lot of calcium, which is good for the health of pregnant women and fetuses.
