What is the method of distinguishing wild yellow croaker from captive bred yellow croaker?

Yellow croaker is a very delicious delicacy, it is rich in protein and trace elements and vitamins, eating yellow croaker is very good for the human body. People with weak constitution and the elderly often eat yellow croaker, which also has a therapeutic effect. Yellow croaker contains trace elements of selenium, which can delay aging and prevent cancer.

Yellow croaker also has a good effect on people with anemia, insomnia and dizziness. <>

Wild croakerThere are wild yellow croakers and artificially bred yellow croakers in the market, and people are stupid and unclear when choosing yellow croaker。First of all, there is a big difference between artificially farmed yellow croaker and wild yellow croaker in taste. Wild yellow croaker has a relatively tight flesh and is also delicious and chewy.

If it is a captive-bred yellow croaker, it is relatively large, and it is relatively fat, and the meat is relatively soft, and the taste is not as pure as wild yellow croaker. <>

Artificially bred yellow croaker can also be distinguished from the appearance of the yellow croaker is artificially bred or wild, the wild yellow croaker is more yellow in color, its fish mouth is also very red, the fish body is more slim, and the belly is very small. Because of the living environment, it is not as fat as the captive-bred yellow croaker. Wild yellow croakers have larger eye circles and mouths, thick scales, and fins on their tails that are much longer than those of farmed croaker.

Farmed yellow croaker, which has limited space to move around in cages. <>

How to tell the difference? Its fins are relatively short and bulky. The wild yellow croaker, which swims in the sea, has a fins and body, which is relatively long and thin.

It can also be seen from the fish scales that the scales of the artificially raised yellow croaker are irregular and easy to fall off. Wild yellow croaker is not only slender, but also has neat and smooth scales, and does not fall off. From these aspects, you can distinguish whether it is wild yellow croaker or artificially bred yellow croaker, and when you buy it, you should buy wild yellow croaker, wild yellow croaker has a better taste and tastes more delicious.

Wild yellow croaker body color is more yellow, fish mouth is more red and bright, fish body is more slender and slender, small belly, because of the relationship of living environment, wild yellow croaker's mouth and eye circles will appear larger, the scales are thick, the meat is relatively close, and it tastes "chewy" and delicious. Artificially cultivated yellow croaker due to the more leisurely life in the cage, lack of exercise, fatter body shape, more swollen fish belly, dark yellow or gray complexion, light color of fish lips.

1. Fish head shape: The head of wild yellow croaker is small and pointed, and the head of farmed yellow croaker is large and round. 2. The length of the fishtail:

Wild yellow croaker has a long and powerful tail, while farmed yellow croaker has a shorter tail. 3. Dorsal fin scales: The dorsal fin of wild yellow croaker has serrated teeth, and the scales are shiny, and the dorsal fin of farmed yellow croaker is smooth and grayish-white.

The head of wild yellow croaker is sharper, and the head of breeding is more round, and the fins of wild yellow croaker are relatively sharp and long, the fish scales do not appear inverted, and the fish tail is relatively large and long, and the farmed one is different, and it can be distinguished from these methods.

First: Compared to the head, the wild yellow croaker has a pointed head, while the farmed head is more rounded. Second:

Looking at the fins, the fins of wild yellow croaker are relatively pointed and long, while the fins of farmed fish are relatively short and wide. Thirdly, observing the fish scales, the scales of wild yellow croaker did not appear inverted, while the scales of farmed fish appeared inverted. Fourth, look at the fish tail, the wild yellow croaker tail is relatively large and long, while the farmed one is relatively short.

We can see from the appearance that the wild yellow croaker is yellowish, and the body of the fish will be more slim. The farmed yellow croaker is relatively fat.

It's hard to tell the difference, but there are a lot of nuances. The wild yellow croaker looks particularly slender, and the outside is particularly yellow, and the mouth of the fish is particularly red. The scales of captive-bred yellow croaker are not particularly regular.

Judging by their color, appearance, body size, and tail of the fish, it is easy for professional fish farmers to tell the difference between them.

Yellow croaker and yellow croaker are not the same type of fish。The differences between yellow croaker and yellow croaker are as follows:

1. The shape is different. Both yellow croaker and yellow croaker belong to the subject of totoaba fish. The head of the yellow croaker has two relatively hard stones, and the stones on the top of the head of the yellow croaker are smaller than the yellow croaker.

In terms of overall size, the size of the yellow croaker is between the large yellow croaker and the small yellow croaker. Large yellow croakers can be taller than people, while yellow croakers are at most the size of an adult's palm; The body of the yellow croaker is flat and elongated, while the yellow croaker is slightly arched.

2. The characteristics are different. Yellow croaker mostly does not emit light, but it does glow at night because the skin of the yellow croaker carries some fluorescent substances.

3. The living environment is different. Yellow croaker lives in the sea and is a type of marine fish. Whereas, yellow croaker is generally farmed and belongs to freshwater fish.

Introduction to yellow croaker

Yellow croaker, also known as yellow croaker, is a general term for yellow croaker of the genus Yellow Croaker of the totoaba family. Born in the East China Sea, there are two hard stones in the head of the fish, called otoliths, so it is also called totoaba fish. The white swim bladder in the belly of the fish can be used as fish gelatin.

Yellow croaker is divided into large yellow croaker and small yellow croaker, which is one of the four major marine species in China. Big yellow croaker is also called Daxian, Golden Dragon, cucumber fish, red melon, **Dragon, osmanthus yellow croaker, king fish, big yellow fish; Small yellow croaker is also called plum, plum fish, small kingfish, small first, small spring fish, small cucumber fish, thick scales, and flower fish. All belong to the class of bony fishes, perciformes, totoaba family, and yellow croaker.

The differences between raw yellow croaker and farmed yellow croaker are: different heads, different tail lengths, different dorsal fin scales, different tastes, and different fish lips.

1. The fish head is different:

The head of wild yellow croaker is relatively pointed, while the head of farmed yellow croaker is relatively large and relatively round and blunt.

2. The length of the fishtail is different:

Wild yellow croaker lives in the sea for a long time, so the tail will be more slender; The farmed yellow croaker lives in a narrow environment such as a cage all year round, and the fish tail is relatively short due to the limited living space.

3. The scales of dorsal fin fish are different:

The dorsal fin of wild yellow croaker is serrate, the overall tip is long and the color is yellowish or transparent, and the scales are not inverted; The dorsal fin of farmed yellow croaker is rough, grayish-white in color, and inverted scales appear.

4. Different tastes:

Wild yellow croaker feels very sticky when eaten, and farmed yellow croaker is very sticky and easy to loosen when stewed.

5. Fish lips are different:

The lips of wild yellow squiak are yellow, and the tartar is abundant and strong, while the lips of farmed yellow croaker are lighter in color and tartar is easy to fall off.

Yellow croaker science:

The large yellow croaker is distributed in the southern part of the Yellow Sea Ridge, the East China Sea and the South China Sea, and the small yellow croaker is distributed in the Yellow Sea, Bohai Sea, East China Sea and the west coast of North Korea. Distribution range map wintering in the deep sea in winter, migrating to the coast in spring, spawning between March and June, scattered in the offshore yellow croaker for bait, mainly feeding on mystic shrimp, hairy shrimp and small fish, and returning to the deep sea in late autumn.

Small yellow croaker has planktonic benthic and swimming animal feeding habits, small food selectivity, mainly feeds on zooplankton, fish and shrimp, etc., among which zooplankton is mainly copepods, fish are mainly gobys, shrimp are hairy shrimp, mysis shrimp, spine-tailed white shrimp and drum shrimp.

The difference between wild yellow croaker and farmed yellow croaker is manifested in appearance, color and meat quality, among which wild yellow croaker has jagged fins on its back, its body color is yellow, the fish mouth is red and bright, and the flesh is tight and tender, while the dorsal fin of farmed yellow croaker is rougher, its body color is gray-white, the fish tail is relatively short, and the meat is soft.

1. The appearance is different

The appearance of wild yellow croaker and farmed yellow croaker is different, among them, the head of wild yellow croaker is more round and blunt, its back has jagged fins, and the mouth color is bright red, while the fish head of farmed yellow croaker is sharper, and the dorsal fin on its back is rougher and shorter, and the color of the mouth is dull.

2. The color is different

The color of wild yellow croaker is different from that of farmed croaker, among which wild yellow croaker is light yellow in color, and its tail is more slender and powerful, because it will migrate in the sea, while farmed yellow croaker is grayish-yellow in color and its tail is smaller, because farmed yellow croaker mostly lives in cages and rarely exercises its tail.

3. The meat quality is different

The meat quality of wild yellow croaker and farmed yellow croaker is different, among which wild yellow croaker will look for food in the sea, and its meat will become tender during exercise, while farmed yellow croaker rarely exercises, mostly trapped in a small space, and someone will feed it, so the meat quality of farmed yellow croaker is relatively loose.

4. Variety introduction

Yellow croaker is an animal of the genus of yellow croaker in the totoaba family, its fish head has two hard stones, it is one of the four major marine products in China, and yellow croaker is divided into two kinds, namely large yellow croaker and small yellow croaker, and yellow croaker belongs to warm and warm migratory fish, will reproduce in the spring and autumn of each year.

<> fish heads are different: wild yellow croaker has a pointed head, while farmed yellow croaker has a larger, rounded and blunt head. Fishtails are different:

Wild yellow croaker has a slender tail, while farmed yellow croaker has a short tail due to its limited living space. The dorsal fin scales are different: the dorsal fin of wild yellow croaker is serrate, the overall tip is long, the color is yellowish or transparent, and the scales will not be inverted, while the dorsal fin of farmed yellow croaker is rough, the color is grayish-white, and there are inverted scales.

1. The difference between wild yellow croaker and farmed yellow croaker

1. The fish head is different: the head of wild yellow croaker is relatively sharp, while the head of farmed yellow croaker is relatively large and relatively round and blunt.

2. The length of the fish tail is different: wild yellow croaker lives in the sea for a long time, so the tail will be more slender; The farmed yellow croaker lives in a narrow environment such as a cage all year round, and the fish tail is relatively short due to the limited living space.

3. The dorsal fin scales are different: the dorsal fin of wild yellow croaker is serrate, the overall tip is long and the color is yellowish or transparent, and the scales will not be inverted; The dorsal fin of farmed yellow croaker is rough, grayish-white in color, and inverted scales appear.

4. Different taste: wild yellow croaker feels very sticky when eating, and farmed yellow croaker is very sticky, and it is easy to loosen when stewing.

5. Different fish lips: the lips of wild yellow croaker are yellow, and the tartar is more and firm, while the color of the lips of farmed yellow croaker is relatively light, and the tartar is easy to fall off.

2. Why is wild yellow croaker expensive?

1. Because most of the water quality is polluted due to industrial reasons, most of the wild fish grow in better water quality, while the wild yellow croaker is purely natural and relatively less polluted, so it is more expensive.

2. The nutritional composition of wild yellow croaker is relatively rich, the water and protein content of wild yellow croaker is relatively high, while the fat content of farmed yellow croaker is relatively high. Therefore, the ** of wild yellow croaker is more expensive.

3. The living environment of wild yellow croaker is relatively harsh, resulting in its tight meat and chewy taste. The farmed yellow croaker lives in a leisurely environment and lacks exercise, and the meat is relatively soft. Therefore, the ** of wild yellow croaker is more expensive.

4. Yellow croaker mainly feeds on mystic shrimp, hairy shrimp and small fish, but the feeding intensity is different in different life periods (wintering period, spawning period and feeding period), among which the feeding intensity is the weakest in January and March in the wintering period, the feeding intensity is in the middle in April and May during the spawning period, and the feeding intensity is strong in June and December during the feeding period.

Many people don't know how to distinguish between wild yellow croaker and farmed yellow croaker, what are the skills to distinguish between the two? I was entrusted by a friend to buy the above two wild big yellow croakers in Xiapu County, Fujian Province that day, the big catty and the small catty cost 5,000 yuan! In recent years, it is rare to buy this kind of natural wild large yellow croaker.

You can't usually touch it. Either one is sky-high. But Huang Guyu, Huang Gu is also Huang Mian Po, of course, this metaphor is too inappropriate, it is just a profiteer who takes a name for himself in order to make money.

Now that there are fewer wild croakers, ** of course it is higher. In fact, if the yellow croaker is cooked well, it tastes good.

A quality of fish is yellow croaker, that variety is also yellow croaker, but think about the buyer, as long as the money is expensive is a good fish, and yellow croaker is also a classification of yellow croaker, so the real yellow croaker can not be excessive. However, the following yellow croaker species can only owe some yellowish brown on the dorsal and upper sides, golden yellow on the lower and ventral surfaces, yellow pectoral fins and pelvic fins, and orange-red lips. Warm temperature cluster migratory fish inhabit the middle and lower layers of the offshore sea with a shallow water depth of less than 60 m, and are distributed in the Taiwan Strait, the East China Sea and the southern Yellow Sea in the South China Sea.

Yellow croaker is commonly known, because the fish flood is in full bloom around the Qingming Festival, fishermen have gone to the sea to catch, and the fish at this time is called yellow croaker and has been passed down to this day. Later, it was divided into large yellow croaker and small yellow croaker. The body is relatively round, and the large individual can reach more than one or two catties.

The meat is tender and tender, with few bone spurs, the market is high, and the individual sells at a sky-high price. It is often reported that the sky-high price of fish slaughtered by restaurants is this fish. However, there are wild and artificially farmed yellow croaker, and it is difficult for people who don't understand it to distinguish.

This phenomenon is common in the mainland and in restaurants. Now the yellow croaker on the market is farmed yellow croaker, the wild one is very rare, the farmed yellow croaker is the main fish in the market, the coastal cities are very clear about these fish, the fish seller will mark it very clearly, plum fish Xiaoxian, white fruit, Balaga is what? Count it its brothers and sisters?

It seems that the catfish is different.
