Introduction: China is a vast country with four inland seas and many rivers and lakes. In the coastal provinces of China, you can often catch some fish and eat more fresh fish. These fish are rich in nutrition and can improve your physical fitness. People often say that eating more fish can improve memory. This statement makes sense. Let's take a look with Bian Xiao. Under what circumstances should cod be better fed?

First of all, cod

The overall shape of cod is rectangular, with flat sides, prominent head, small eyes and plug-like fascia at gills. From the appearance, the teeth and jawbone are prominent. There are many kinds of cod, the common one is Pacific cod. This cod is mainly distributed in the North Pacific Ocean, including China, Japan and China, and mainly distributed in the Bohai Sea and the Yellow Sea. This kind of fish likes to grow in areas where cold water enters Tibet, and mainly eats small yellow croaker, small fish and crustacean cartilage animals.

Second, the growth environment

Cod is a cold-water animal, and most of the water temperature is 0~ 16 degrees, mainly inhabiting the deep water layer above 200 meters. In infancy, they like to move at night, while in adulthood, they lay eggs from deep water to shallow water. Mainly eat some krill invertebrates, like to migrate in winter, and spend the winter on the seabed with a water depth of about 50 meters. Cod is widely distributed, mainly in the Yellow Sea, Shandong fishing grounds and other places in China.

Third, the mode of reproduction

Cod lays eggs in winter every year, but the best time to lay eggs is from October to February every year, with an egg quantity of about 250,000 ~ 1 10,000. A fertilized egg of a fish can hatch a young fish in about 15 days at normal water temperature. Cod is tender, with few thorns, and rich in fish, protein and fat. It is a fine fish, and it also has a certain health care function, which can help people to promote blood circulation and remove blood stasis.
