Why are the bones of some marine fish blue?

Because of the changes in the genes and living environment of marine fish, the bones of some marine fish are blue. The reason why the bones of marine fish turn blue is actually because there are many of them around the bones of marine fishCollagen, and these collagens contain a type of biliverdin。Biliverdin is an organic substance that is also present in the human body.

When hemoglobin in the human body.

After decomposition, this organic substance is produced in the body.

The human body experiences bruising after an impact, so the bruising is due to the formation of biliverdin. Biliverdin itself is not poisonous, although it looks disgusting, but the sea fish is still relatively good, and the taste is not bad. However, some people do not know that the bones of some marine fish turn blue, so they think that this fish is poisonous.

In fact, there are many kinds of marine fish whose bones turn blue, such as needlefish.

When people eat needlefish, many people think that the fish has gone bad, but in fact, it is just due to its own genetic changes or direct feeding by unscrupulous vendors.

However, the bones of the needlefish are originally blue, but when handling this fish, it is necessary to carefully select the flesh and treat it at the same timeSashimiIf you eat it, the taste is still good. If fishermen catch this kind of fish, they generally do not sell it, but only choose to eat it themselves.

Therefore, although the bones of some marine fish are blue, the flesh is not affected and does not produce toxins. Therefore, if someone eats this fish, there is no need to panic.

However, it is relatively rare in the ocean, after all, most people eat relatively ordinary marine fish, and this kind of marine fish is usually difficult to catch, once it is touched by fishermen, then most of the fishermen will take it to their homes for their families to enjoy, and will not take it to the market to sell. If you see this fish, you don't have to make a fuss.

This is because of the food problem of these fish, and the food that these torpedoes have eaten for a long time is the root cause of the blue color of the bones of marine fish, or because of a substance in the living environment.

According to relatively recent research results, these blue-green colors are mainly caused by biliverdin in the collagen around the fish eggs, the molecular structure of the so-called biliverdin, which also appears in the human body, in which it is hemoglobin. After decomposition, it will be produced, why ecchymoses in the human body take on a blue-green color because of the presence of this substance.

It is caused by the biliverdin in the collagen around the fish bones, which is not toxic and can be eaten.

Labridae of the genus Achoerodus (a locally conserved species).

The picture below shows the green-lipped blue-lipped mammoth, Achoerodus viridis, which is a female.

Distributed in the waters of southeastern Australia, inhabiting depth of 5-65 meters, body length up to 175 cm, inhabiting the continental shelf of rocky bottom, feeding on crustaceans, fish, starfish, molluscs, etc.

Others include the blue parrotfish.

The whole body is blue sea fish called American red fish, also known as eye-spotted totoa, red pseudo-shiju state first stove fish, red drum fish, black spotted red perch, spotted tail perch, etc., belonging to the order perch, totoaba family, pseudotoaba genus. The body is spindle-shaped, the appearance is similar to that of domestic large yellow croaker, the body color of the adult is reddish above the abdomen, there are 1-4 round black spots on the base of the tail peduncle of the juvenile fish, and the edge of the caudal fin is blue.

It's a blue devil. A kind of damselfish, the whole body is blue, the end of the dorsal fin family imitates black spots, the distribution of the large world is chaotic in the tropical Pacific Ocean, is a common seawater ornamental fish, strong physique, fierce character.

The picture below shows the green-lipped fish Achoerodus viridis, and the larger one is the female.

Distributed in the waters of southeastern Australia, inhabiting depth of 5-65 meters or answer, body length can reach 175 cm, inhabit the continental shelf of lead in the rocky bottom, and feed on crustaceans, fish, starfish, mollusks, etc.

Others are: Blue parrotfish.

According to relatively recent research results, these blue-green colors are mainly caused by the biliverdin in the collagen around the fish bonesThe molecular structure of the so-called biliverdin, this substance will also appear in the human body, and this substance will be produced after the hemoglobin in the human body is decomposed.

But you can rest assuredThis biliverdin itself is not toxicIt's just that it looks disgusting. And I heard that the taste of sharpmouth fish is still good, as long as you are not frightened by the blue-green color of the bones, it is also good to taste it. Generally, the number of bones in a fish represents the degree of its evolution.

It's like we humans don't have tails. Fish with few or no spines evolved more perfectly than fish with many spines. However, the specific gravity of seawater also has some truth, but it is not the key.

It turns out that this fish is indeed a serious sea fish, its name is called jaw needlefish, and the people on the seaside call it "green stripe", because the fish bones of this fish are blue-green, so it has such a name. And this blue-green fish bone is also the biggest feature of this green stripeOnly this kind of green strip will appear like this, so the vendor said that it is normal, you can eat it with confidence, there is no need to worry too much, the things they sell by the seaside are all real materials, and there will be some drugs to feed the fish to promote growth.

Needlefish, that is, jaw needlefish, also called billfish, needlefish, is a kind of warm water fierce upper fish, can be eaten, the fish meat is white, the fish bone part is emerald green, the fish bones are hard, there is a row of horizontal spines in the fishing line, and the fish belly contains rows of oblique spines. Veteran foodies know thatMost of the fish of the order of needlefish are rich in biliverdin, and biliverdin is not poisonous and can be eaten, and green bones are the certification of authentic needlefish.

That's because they have to adapt to the environment, so they become this color.

This fish, called the snake whit, is the only surviving snake tooth fish and is a rare species found off the west coast of North America and is an important commercial and recreational fish.

This is because of the sea fish, his body structure is relatively special, so the bones are all blue.

Because the living environment of those fish is relatively special, the traits are also relatively special.

Because the body structure of each animal is different, it is blue.

Because their own physique structure is very special, so it will be like this.

It may be because these fish grow in different environments and have different structures.

It may be because the body contains some heavy metals or other elements.

It may be because they have special genes, so the bones are blue.

It's actually a chemical entanglement.

The bones are blue and are unique to this species of marine fish.

I guess it's soaked in blue water.

This is because of their special body anatomy.

It's because of the damage of the sea.

These cancer cells have not yet encountered food that will wake them up.

responsibility, let them do their duty.

It is caused by the biliverdin in the collagen around the fish bones.

This is because of the erosive effect of salt water on its bones.

Because the chromosomes in the body of fish are different, it is not surprising that they will appear different colors.

Because of the biliverdin in fish in the deep sea, the bones we see are blue.

Because some marine fish produce some substances in their bodies, which causes the bones to be blue.

According to the latest research results, these blue-green colors are mainly caused by biliverdin in the collagen around fish bones, the so-called biliverdin is the molecular structure shown in the figure below, this substance will also appear in the human body, and this substance will be produced after the hemoglobin in the human body is decomposed. It is because of the existence of this substance.

The blue-boned fish is an endemic fish that grows in the waters of Kyushu, Japan, and is one of the favorite fish of the people of Kyushu, Japan. What is special about this fish is that even the bones are naturally blue, the kind of inky blue that dawns on.

It is more than one meter long, slender and delicate, one is about 2 catties to 3 catties, and the bigger the one, the more beautiful.

Due to its soft and creamy texture, it is not suitable for sashimi, and is most popular in Japanese for pan-frying or boiling. When frying, it is necessary to fry the flowers and powder, but if you want to eat the original flavor, the boss will definitely recommend boiling it in sauce, and boiling it with 10,000 characters thick soy sauce sesame oil flavor is the same, and the fish made is tender and smooth, full of home-style flavor.

Yes, homely, that's what Akita Tsu, hidden in the corner of the lobby of the Zhuhai Special Economic Zone Hotel at the junction of Haizhu Middle Road and Zhongshan Sixth Road, is after.

And the chef is best at home-cooked Japanese food, especially tempura. The owner and head chef here was born in a Japanese restaurant in a five-star hotel, and he learned from a Japanese master, and he felt that the best way to reflect the characteristics of Japanese cuisine was not those expensive dishes, but home-cooked Japanese food, for which everything here is trying to match the recipe of Japanese daily cuisine, and even the tempura noodles here are specially imported from Japan by the local time-honored Showa brand.

As for the sauce, in addition to being shipped directly from Japan, the chef will also adjust the sauce according to the Japanese recipe, so that the resulting dishes will have the essence of Japanese cuisine.

For example, the tempura that Japanese customers must order here, use A-grade tempura powder and egg yolk, ice water to boil the powder, and the oil is Shun Mark tea seed oil, which is fried in a special tempura copper wok at an oil temperature of 160 to 170, and the oil color is changed immediately as soon as it becomes turbid, which is basically a change in the city, which is stricter than many large chain stores.

The bones of some marine fish are blue because the sea has been in the water for so long.

The blue color of the bones of marine fish is caused by some substances in the body.

The blue color of the bones of some marine fish is due to the presence of biliverdin in fish in the deep sea.

It is caused by the biliverdin in the collagen around the fish bones.

Because they have lived in the sea for a long time, some things are alienated, and some things are innate.

It is the color of the animals of the deep sea, and it is pure and natural without pollution, so it is blue.

The bones of most marine fish are not blue, but there are a few exceptions, the only surviving snake toothfish, a rare species found off the west coast of North America and an important commercial and recreational fish. About 20% of snake whiting will have blue or blue-green flesh because they contain a substance called biliverdin in their blood, which makes their flesh blue or blue-green, but does not change the taste or nutrients. Of course, so far, this has not been supported by very direct evidence, so it is only a human conjecture.

After cooking, their color fades and they return to their normal white.

Although they are called snake whiting, they get their name solely because they resemble them and nothing else.

It is a member of the six-line fish family and the only surviving species of the subfamily plesiodontidae. Snake whiting has 18 canine-like teeth, so it is also called long snake tooth monolith, which makes them omnivorous fish that eat everything. Whether it is a small octopus or a large rock fish, whether it is shelled or unshelled, they are all eaten in the stomach first, and the amount of food is breathtaking.

They are mainly found in rock formations about 10 to 100 meters deep off the west coast of North America, and can reach a maximum depth of more than 475 meters. Although it is very edible, it will not grow meat as unscrupulously as a catfish, with an average of 45 centimeters and only 150 centimeters to death. Its liver is rich in vitamin A and its flesh is delicious, making it a popular sport fishing and commercial fish.

But if you want to try what the blue fish tastes like, it's a matter of luck. However, I can't say for sure, with a one-in-five probability, no matter how difficult it is, it's easier than winning the lottery!
