1. What is Bering Strait cod?

Bering Strait cod is distributed throughout the Arctic region. It is a typical cold-water fish. When the temperature exceeds 5°C, it disappears. It is a small to medium-sized fish with a maximum body length of 36 cm. It is one of the important economic fish in the Arctic region. In summer, cod mainly live on the edge of the ice zone in the Barents Sea in the Kara Sea region. The young cod feed on small phytoplankton and zooplankton. As it grows, the plankton it eats gradually changes from small to large, and it partially preys on small fish. In September every year, cod begins to migrate westward and southward, and lays eggs in sub-zero temperatures in winter. The eggs are floating eggs, with a total egg volume of 9,000 to 18,000. Due to the low water temperature, the incubation period is as long as 4 to 5 months. The growth rate of cod in the cold Arctic is extremely fast. At the age of 3, the average body length is 17 cm, 4 years old can reach 19.5 cm, 5 years old is 21 cm, and 6 years old is 22 cm. The maximum age of cod can reach 7 years old. The sexual maturity age of cod is generally 4 years old, and most of them only spawn once in their lifetime, and stop eating during the spawning period. After spawning, some Arctic cod swim into the estuary or downstream of the river, and then swim into the open sea.

Cod (local name: bighead green, bigmouth fish, bighead fish, pollack, water mouth, wide mouth fish, bighead fishy, ​​stone intestine fish). Pure cod refers to fish of the genus Gad, which is divided into Atlantic cod (Gadus morhua), Greenland cod (Gadus ogac) and Pacific cod. [1] Under the order Gadformes, there is the family Gadidae.

Is cod a marine fish or a freshwater fish?

Cod is a marine fish. Cod lives in the ocean, so it is a marine fish and is adapted to the normal life in the sea. Cod is a cold-water bottom-dwelling fish that feeds on invertebrates and small fish. They do not live in fresh water, so they are not freshwater fish. From a global perspective, the distribution range of cod is very wide. In summer and autumn, they live in the cold water area of ​​the Yellow Sea, and in winter they migrate to the coastal mud bottom area with a depth of 50 to 80 meters to hibernate. Especially in the North Pacific region, such as the Bering Sea and the Sea of ​​Okhotsk, there are many cod. The protein content in cod meat is higher than that of salmon, pomfret, shad, and hairtail, and the fat content in the meat is only 0.5%, the same as shark, which is 17 times lower than salmon and 7 times lower than hairtail.

4. The difference between black cod and silver cod

It's basically the same thing!

One of the common names for black cod in the market, butter fish, generally describes this species. In China, it has a more resounding name "silver cod" (official name in Japan: ギンダラ/silver cod; official name in Hong Kong and Singapore: silver cod). Black cod (silver cod) is distributed in the northeastern Pacific Ocean from the Bering Sea to Central California. Although black cod is often called black cod, they do not belong to the cod family, but to the unique family of sablefish.

But it should be distinguished from the dragon cod.

Dragon cod is a fish called snake mackerel, commonly known as oil fish or jade fish in Chinese. It contains a natural wax ester called snake mackerel toxin. Wax ester is difficult to digest in the human body. Eating it can easily cause stomach cramps, oil accumulation in the rectum, and oily diarrhea. Some Western countries and Japan have listed it as a fish species that is prohibited or limited in consumption. Some unscrupulous merchants will use this fish to impersonate high-priced marine fish such as cod, making it one of the materials for fake cod on the market that costs more than ten yuan per pound. However, eating this fish can cause diarrhea and even death in severe cases.
