First of all, the real cod

True cod refers to cod of Codiformes, Codidae and Codidae, and there are three main types:

Atlantic cod

Real Greenland cod

Pacific cod

Pacific cod, also known as bighead carp and fish head, is not much different from Atlantic cod in appearance, taste and nutrition, but it is much smaller, so its share in the market is very small, but it is still almost invisible in China, with an annual catch of about 400,000 tons.

Greenland cod, only found in the waters around Greenland, is very rare and has a single distribution area. Because there are Atlantic cod in the local area, no one usually catches Greenland cod, and the annual catch is 200-300 tons, which can be said to be very small.

Atlantic cod is mainly produced in cold water in the northeast and northwest of the Atlantic Ocean. It is the largest cod in the world at present, and the most common real cod on the market now is Atlantic cod.

Second, silver cod.

There are two kinds of silver cod in China population: Antarctic Bermuda grass (French silver cod) and naked cod (black cod).

High pressure French silver cod-small canine Antarctic fish

English name: Patagonian toothfish, Chilean bass.

Latin name: Dissostichus eleginoides

Chinese name: French silver cod (market name), Antarctic cod, Chilean sea bass, Patagonian pike.

Antarctic canine fish, also known as French silver cod, belongs to perciformes and is widely distributed in the Pacific Ocean, Atlantic Ocean and Indian Ocean near Antarctica. It is a deep-sea fish with a body length of more than 2 meters.

This kind of fish does not grow on the coast of France, so it is called French silver cod, because there are two islands belonging to the southern territory of France in the South Indian Ocean: Kerguelen Islands and Croce Islands. Around the fishing rights near the two islands, there can only be one French fishing boat and six fishing boats are registered.

After fishing, the processing and packaging work was completed in reunion island, another French island in the southeast corner of Africa. (So you will see that the origin of some high-end silver cod will be marked as: French Reunion)

Domestic prices vary. The price from New Zealand is higher, about one kilogram in 290 yuan, slightly lower in Chile and France, and the price of different specifications ranges from 230-260 yuan per kilogram.

Growing in the natural pollution-free deep sea, fish meat is rich in various nutrients, such as unsaturated fatty acids, protein, calcium, magnesium, zinc, selenium and other trace elements. The meat is white and tender, and the taste is smooth and delicious.

This fish also has a close relative, Cynodon squamata, commonly known as Chilean sea bass in Chinese, Atlantic toothfish/Chilean toothfish in English, and Dissostichus mawsoni in Latin, which is mostly imported from Chile.

Wikipedia certifies the naked cod.

English name: mink fish (American market name)/black cod (Alaska common name)

Latin name: Anopheles umbrella

Chinese names: haddock (entry name provided by entry-exit inspection and quarantine department) and silver cod (commonly used in Japan, Hong Kong and Singapore).

Black cod is smaller than French silver cod, with a body length of 120 cm, and the general commercial fishing standard is 7~ 10 kg. Mainly distributed in the North Pacific Ocean, the habitat depth is 150- 1500m.

The commercial fishing of haddock in Alaska is strictly restricted.

According to the data provided by NOAA, in 20 16, haddock fishing in gulf of alaska began in March 1, longline fishing boats ended in 1 October 71,trawlers ended in1October1.

As the most expensive bottom fish commercially caught in North America, the taste of black cod meat is amazing. Because black cod lives in the deep sea, the temperature of the sea water is very low, so this kind of fish has high oil content, soft and smooth fish, and a faint milk flavor. Many gourmets even call it "cream" in fish.

Judging from the market quotation, the price of French silver cod is lower than that of black cod.

Third, oily fish.

Oil fish is the general name of Agkistrodon acutus and Agkistrodon acutus, commonly known as spring fish, and other nicknames include "round snow (cod) fish", "white jade dolphin" and "butter fish". Oil fish is a mackerel, which is common in tropical and temperate waters all over the world.

Oil fish is a deep-sea fish. There are more than 40% wax esters in the weight of oil fish. Because the human body can't decompose and absorb wax ester, it will have diarrhea after intestinal stimulation, and it will discharge orange oil ester, but it will not be poisoned. It is understood that oily fish are mostly used for industrial purposes abroad, and many countries do not recommend people to eat edible fish.

Although the wax ester contained in oil fish is not toxic, it is difficult for human body to digest and accumulate in rectum. Therefore, after some people eat it, it will lead to diarrhea, gastrointestinal cramps and other discomfort, and oil may continue to flow out of the anus. After eating, patients will have symptoms as soon as 30 minutes, and most of them will recover within two days.

Some unscrupulous businessmen in China pretend to be expensive cod and salmon with cheap oily fish for high profits.
