Difference Between Cod and Squid

The most important thing is the price. Although it is possible that cheap fish may be sold at a high price to deceive people, good fish will never be sold at a loss. The market price of cod and silver cod is generally 100-200 yuan per catty. If the price is much lower than this, you should be careful, and if it is higher, you will lose a lot.

Regardless of whether the fish is expensive or not, it comes from the same fishing boats, and the price may vary several times in different stores. The cost price of pure Saury cod is estimated to be between 80-110.

2. Look at the appearance

Nowadays, almost all cod is called Alaskan cod, Canadian cod, and Atlantic cod by merchants, but even if you buy it on an e-commerce platform, you should try to find out through the promotional pictures.

The most obvious one is the Icelandic cod, which is a kind of flatfish. The fish is flat, and of course the fish meat is also flat like the one below. If it is round, then they are lying to you.

The silver cod is generally large in size, with dense scales, very white and clean meat, and the fillets are oval and close to round, which are its characteristics. The most important appearance feature of the real cod is that it has a "beard" and a clear line in the middle of the fish body.

Cod does not have these. The two types of fish we usually see are either frozen or directly made into fish paste.

The oily fish that everyone is most concerned about is indeed similar to silver cod after being cut into sections, but the cross-section is flatter and the meat is not as white. Because of the high fat content, there is a clearer red line between the fish meat.

Cod

The cod has an elongated, slightly laterally flattened body, a large head, a large mouth, an upper jaw slightly longer than the lower jaw, and a tail that tapers toward the back. It is generally 25 to 40 cm long and weighs 300 to 750 grams.

The vibrissae on the neck are equal to or slightly longer than the eye diameter. Both jaws and vomer have velvety teeth. The body is covered with small round scales that are easy to fall off. The lateral line is obvious, there are 3 dorsal fins and 2 anal fins. All fins have no hard spines and are composed entirely of fin rays. The body color varies, from light green or light gray to brown or light black, or from dark red to bright red; the head, back and sides of the body are gray-brown with irregular dark brown markings, and the belly is gray-white.

The fish with square scales is oil fish, and merchants will shave off the scales to pass off the oil fish as cod. The meat of oil fish is yellow with red blood streaks, while the meat of cod is white.

You can't tell by looking at it this way. The cheap ones are usually oil fish, and the ones that cost a few hundred are most likely cod.

3. How much is cod per pound?

The price of frozen food in the supermarket ranges from 5 yuan to 8 or 9 yuan per pound, and will not exceed 10 yuan.
