CATDOLL : CATDOLL: How to distinguish wild and farmed yellow croaker

1. How to distinguish wild and farmed yellow croaker

1. In fact, it is not complicated to distinguish whether the yellow croaker is dyed: the yellow color on the belly of the real yellow croaker is a natural light yellow, and the abdomen and fins are darker in color and will not fade; while the dyed color is easy to fade, and it is more obvious after the fish is thawed.

2. Huangyuanhe fish and yellow croaker are similar in appearance, the biggest difference is that yellow croaker has a distinct yellow color, while yellow croaker is blue-gray.

Experts explain the cracked pants: illegal merchants "stealing and replacing the original"

However, a marine fish expert from the Chinese Academy of Fishery Sciences told the reporter that based on the reporter’s description, it can be judged that what is sold in the market is not yellow croaker, but "yellow croaker." The expert said that the production of yellow croaker (also known as large yellow croaker) in my country’s waters is very small, and there are currently no large schools of fish, so the price is relatively expensive and cannot be less than 10 yuan. Therefore, there are often unscrupulous merchants in the market who dye yellow croaker with artificial pigments such as sunset yellow or lemon yellow and sell them as yellow croaker. It is easy to distinguish them: the yellow color on the belly of a real yellow croaker is a natural light yellow, and the color of the abdomen and fins is darker and will not fade; while the dyed pigment fades easily, and it is more obvious after the fish is thawed.

2. What is the difference between farmed yellow croaker and wild yellow croaker?

In addition to the difference in appearance, farmed yellow croaker and wild yellow croaker also have great differences in taste. The specific differences are as follows:

Dorsal fin. The dorsal fin of wild yellow croaker is serrated and transparent or slightly yellow in color; the dorsal fin of farmed yellow croaker is rough and grayish white in color.

The body is wide. Wild yellow croaker is smaller in size, while farmed yellow croaker is larger in size.

Trunk. The trunk of wild yellow croaker is thin and skinny, while that of farmed yellow croaker is thick and fat.

Viscera: The viscera of wild yellow croaker are clean, while those of farmed yellow croaker are dirty.

Fish lips. The lips of wild yellow croaker are yellow and have a lot of tartar, which is firm, while those of farmed yellow croaker are less and more prone to fall off.

Taste: Wild yellow croaker is very sticky when eaten, while farmed yellow croaker is very sticky, which is most obvious when stewed.

3. How to distinguish wild yellow croaker from artificially raised yellow croaker?

Yellow croaker is a very delicious food. It is rich in protein, trace elements and vitamins. Eating yellow croaker is very good for the human body. People with weak constitutions and the elderly often eat yellow croaker, which has a therapeutic effect. Yellow croaker contains trace elements such as selenium, which can delay aging and is also effective in preventing cancer. Yellow croaker also has a good effect on people with anemia, insomnia and dizziness.

There are wild yellow croakers and farmed yellow croakers on the market. People can't tell the difference when choosing yellow croakers. First of all, there is a big difference in the taste between farmed yellow croakers and wild yellow croakers. The meat of wild yellow croakers is relatively dense and tastes delicious and chewy. Farmed yellow croakers are relatively large and fat, with soft meat and a less authentic taste than wild yellow croakers.

The appearance of the artificially raised yellow croaker can also be used to distinguish whether the yellow croaker is artificially raised or wild. The wild yellow croaker is more yellow in color, its mouth is also bright red, its body is slimmer, and its belly is small. Because of its living environment, it does not eat as much as the artificially raised yellow croaker. The eye circles and mouth of the wild yellow croaker are larger, the scales are also thicker, and the fins on the tail are much longer than those of the farmed yellow croaker. The farmed yellow croaker has limited space to move in the cage.

How to distinguish? Its fins are relatively short and its body is relatively bloated. The fins and body shape of wild yellow croaker swimming in the sea are relatively longer and thinner than those of Pai Hua Zao. It can also be seen from the scales that the scales of artificially raised yellow croaker are irregular and easy to fall off. Wild yellow croaker not only has a slender body, but also has neat and smooth scales that will not fall off. From these aspects, you can distinguish whether it is wild yellow croaker or artificially raised yellow croaker. When buying, buy wild yellow croaker. Wild yellow croaker tastes better and tastes more delicious.

Wild yellow croaker has a yellower body, a redder mouth, a slimmer body, and a smaller belly. Due to its living environment, the mouth and eye circles of wild yellow croaker appear larger, the scales are thicker, and the meat is arranged relatively tightly, which makes it chewy and delicious. Artificially farmed yellow croaker lives in cages more leisurely and lacks exercise, so it is fatter, has a bulging belly, dark yellow or grayish skin, and has light lips.

1. Fish head shape: The head of wild yellow croaker is small and pointed, while the head of farmed yellow croaker is large and round. 2. Tail length: The tail of wild yellow croaker is long and powerful, while the tail of farmed yellow croaker is relatively short. 3. Dorsal fin and scales: The dorsal fin of wild yellow croaker is serrated and the scales are shiny, while the dorsal fin of farmed yellow croaker is smooth and the scales are grayish white.

The head of wild yellow croaker is relatively pointed, while the head of farmed one is relatively round. In addition, the fins of wild yellow croaker are relatively pointed and long, the scales are not inverted, and the tail is relatively large and long. However, it is different for farmed ones, and they can be distinguished by these methods.

First: Compare the head. The head of wild yellow croaker is more pointed, while the head of farmed fish is more round. Second: Look at the fins. The fins of wild yellow croaker are more pointed and long, while the fins of farmed fish are shorter and wider. Third, observe the scales. The scales of wild yellow croaker do not have the phenomenon of inverted insertion, while the scales of farmed fish do. Fourth, look at the tail. The tail of wild yellow croaker is longer and longer, while that of farmed fish is shorter and smaller.

4. How to tell whether the small yellow croaker is wild or farmed?

Generally, there are fewer wild yellow croakers during the fishing moratorium. The appearance and taste of farmed yellow croakers are very different from those of wild yellow croakers. From the appearance, wild yellow croakers are more yellow, their mouths are more red, their bodies are more slender, and their bellies are smaller. Because of their living environment, their mouths and eye circles appear larger, their scales are thicker, and their meat is arranged relatively tightly, making them chewy and delicious.

The farmed yellow croakers, however, are relatively relaxed in cages and lack exercise, so they are fatter, have swollen bellies, dark yellow or grayish skin, and pale lips. In addition, the fins of wild yellow croakers are clean and complete, with longer fins. When they are caught from the sea, they die from the bursting of their swim bladders due to reduced air pressure, without much painful struggle.

The scales and fins will not show signs of congestion. The fins will look a little red and a little damaged, and the fins will be shorter. If there are red spots and scars on the fish, it can be confirmed that they are farmed.

Because artificially cultivated yellow croakers are usually kept in cages, they are easily injured when swimming in a small space. At present, some deep-sea farmed yellow croakers are somewhat similar to wild yellow croakers in appearance, but the meat tastes a bit soft and the taste is not as pure as wild ones.

Additional information:

Small yellow croaker (Larimichthys polyactis) is also known as small yellow croaker, a vertebrate, bony fish of this class, Sciaenidae, also known as: small fresh, big eyes, colorful, cucumber, ancient fish, yellow scale fish, small spring color, golden dragon, thick scale, also called "yellow croaker", "small yellow flower". It is similar to large yellow croaker, but with a longer head, smaller eyes, larger scales, short and wide caudal peduncle, 5-6 rows of scales from the starting point of the dorsal fin to the lateral line, golden yellow.

Small yellow croaker feeds on planktonic benthic and swimming animals, and has little selectivity for food. It mainly feeds on zooplankton, fish and shrimp, among which zooplankton is mainly copepods, fish are mainly goby, and shrimps include hair shrimp, mysid shrimp, white shrimp and drum shrimp.

In the southern Yellow Sea and the northern East China Sea, small yellow croaker mainly feeds on swimming animals, but the feeding intensity varies in different life periods (wintering, spawning and foraging). The feeding intensity is the weakest in the wintering period (January to March), in the middle during the spawning period (April to May), and the most vigorous during the foraging period (June to December).

Small yellow croaker is rich in protein, sugar, fat, calcium, phosphorus, iron, potassium, sodium, magnesium, selenium and vitamin A, which are various nutrients needed by the human body. It has high edible value. In addition, both traditional Chinese medicine and modern medical research have found that small yellow croaker also has quite high medicinal value.

For example: fish maw has the effects of moistening the lungs, strengthening the spleen, and replenishing qi and blood; the gallbladder can clear away heat and detoxify, calm the liver, and lower blood lipids; fish phosphorus can be made into pharmaceutical glue; the testis is used to extract protamine and arginine; and the ovary can be used to extract lecithin.
