Two days ago, the Internet exposed an incident in which a Harbin trader threw an unknown liquid on the pond-raised Gaga fish and packaged it as wild river fish for sale. This bad method has aroused the dissatisfaction of the majority of netizens, and has also sounded the alarm for consumers to purchase fish.
But you know what? In addition to pond fish posing as wild fish, there are also the following kinds of fish, which are also very easy to be "impostered"!

Rumors about the replacement of the basha fish with the dragon fish, I believe many people have some understanding. Without careful distinction, it is indeed difficult to find the difference between the two from the appearance of the fish alone.
When purchasing dragon fish, you should pay attention to the following points:
1. Look at the price: the new price below 30 yuan is generally basa fish.
2. Look thin and thick: the fish is thin, the surface is smooth, and the texture is clear; The fish is thick and deeper in texture.
3. Flatness after peeling: The body of the dragon fish is flat, the fish skin can be removed in its entirety, and the surface of the peeled fish meat is smooth and flat, retaining the original shape of the fish body. Basha fish body is relatively round, usually close to the vertebrae cut into two pieces of fish meat, and then peel, each piece of fish meat on both sides of the asymmetrical (one side is the fish skin side - the side is the vertebral side), basa fish is not easy to peel, close to the spine to cut the fish fillet is difficult to flat, usually the surface of the fish will appear uneven.
4. Look at the color: the fish body is yellowish, generally for the basha fish.
< h1 class= "pgc-h-center-line" > salmon</h1>
Another fish that is most susceptible to imposters is salmon, and it is difficult for consumers who buy salmon for the first time to distinguish between real salmon and rainbow trout.
When choosing salmon, pay attention to the following points:
1. Look at texture and color:
Salmon: high in fat, orange-yellow flesh, whiter on the surface, wider lines, and blurred edges.
Rainbow trout: Low fat content, thin lines and very hard edges, that is, red and white are obvious.
2. Look at the thickness:
Salmon: The meat is soft and is generally cut into thick pieces (about 0.7cm-1cm).
Rainbow trout: The meat is relatively hard, so it is more chewy, and it is generally thinly cut (0.3-0.5 cm).
3. Look at the gloss:
Salmon: Look at the light with oil.
Rainbow Trout: Dim in the light.
< h1 class= "pgc-h-center-line" > cod</h1>
As a deep-sea fish, cod has a high nutritional value, but some merchants will use oil fish to pretend to be deep-sea fish for sale in order to make a profit. Oil fish contains wax esters, although there is no poison, but it is more difficult to be digested by the human body, will accumulate in the rectum, so some people will have diarrhea, gastrointestinal cramps and other adverse reactions after eating oil fish.
When buying cod, pay attention to the following points:
1, look at the shape:
The skin of the silver cod is whitish or grayish white, the color is lighter, the scales are small, the body of the fish is elongated and flattened, cylindrical, the back of the body is dark blue-gray or greenish-gray, and the abdomen is gray or pale.
The fish has a round lip, a slightly longer body, a round anterior part, a flattened posterior part, an arc of the back of the head, a black or bluish-black upper body, a grayish-white abdomen, a slightly black fin, and most of the scales on the side of the body have black edges, from behind the gill hole to the front of the pectoral fin, the black patches are thicker and thicker into a large black spot.
2. Look at the scales:
Silver cod scales are small, with small silver dots on the body, lighter flesh color; while the scales of oil fish do not have this feature, the general merchant will peel off the scales of oil fish to confuse.
3, look at the feel:
It is difficult to distinguish between oil fish and cod after freezing, but after thawing, cod will be very smooth to the touch, cod skin is very smooth after thawing, like a mucus membrane; while oil fish is relatively rough, silver cod is not scraped when it is sold, but oil fish are scraped and sold.
4, look at the color:
The skin of the cod is white or gray, the color is lighter, and the flesh is delicate. The skin of the oil fish is gray-black, dark in color, mesh-like, and the flesh is hard and rough, and the oil fish meat can be found yellow on closer inspection.
The aquatic market is mixed, and consumers who do not know the truth can easily be deceived. If the source of counterfeit fish used by bad merchants is unknown, it is difficult to ensure that there will be no food safety accidents after eating! Therefore, the purchase of aquatic fish and meat must go through formal channels, and the merchant must also confirm whether the documents of aquatic products are complete when purchasing goods, so as to avoid bringing health and economic losses to consumers.
