Is the meat of marine fish salty? Are the meat of marine fish salty?

Why are marine fish not salty, marine fish have a strong ability to excrete salt, marine fish have a strong ability to excrete salt, in addition to excreting a small part of salt from the kidney, the kidney excretes a small part of salt, and also has a special salt excretion organ, that is, the "chlorine secretion cells" located in the gill sheets, that is, the "chlorine secretion cells" located in the gill sheets. Because different organisms in the sea or on the seashore have salt glands or gills or kidneys to exercise their respective functions. Salt glands are part of the salt-draining glands of birds and reptiles.

Because it is located in the orbital region, it is also called the orbital gland. The main component of the secretion is sodium chloride. Animals such as seabirds and sea lizards that live near and in the sea have particularly developed salt glands.

These animals feed on invertebrates and seaweeds from seafood, and the salt content in their food is high. When an animal eats, the osmotic pressure of body fluids becomes too high. Pass the salt <>

The glands excrete excess salts from the body to maintain the osmotic balance of body fluids.

The meat of marine fish is not salty. The fish that live in the ocean drink the salty and bitter water all the time, but why is their meat not salty? This is because fish in the ocean have their own "desalinations" that remove salt from the salty water they drink.

This "desalination" of bony fish and cartilaginous fish are different. Bony fishes in the ocean have a strong ability to excrete salt, and have specialized organs for salt excretion, which grow in the gills of the fish and are made up of "chlorine-secreting cells". "Chlorine cells" can secrete chloride, like a "freshwater workshop" on the fish, which can desalinate the seawater entering the fish, and the efficiency is quite high, even the world's most advanced "seawater desalination" is beyond the dust.

In order to compensate for the loss of water, they take the method of drinking more water and less urinary to maintain low osmolar pressure in the body. The "desalination" of cartilaginous fishes in the ocean, such as sharks, is another example, which does not have "chlorine-secreting cells" and uses the action of urea in the body to remove salt. The <> of urea in their bodies

The amount is almost 100 times higher than that of other aquatic animals, and these urea can not only keep cartilaginous fish with high osmotic pressure of body fluids and reduce salt infiltration, but also accelerate the excretion of salt in the body, which can be called the "life-saving medicine" of cartilaginous fish. In addition, there are fish such as eels that can breed in the ocean and grow in fresh water. This is because the cell tissue on the gills of the eel is more powerful than the "chlorine cell" function, and it has a dual function, whether it is seawater or fresh water, it can adapt, so the meat of the eel is not salty.

Therefore, the meat of marine fish does not have to be salty, and it varies depending on the type of fish.

No.

This is because fish in the ocean have their own "desalinations" that remove salt from the salty water they drink. This "desalination" of bony fish and cartilaginous fish are different. Bony fishes in the ocean have a strong ability to excrete salt and have organs that specialize in rejecting salt.

Due to the efficient work of these salt-secreting cells, the salt content of marine fish is always kept low.

Cartilaginous fish have another set of skills to keep their bodies low in salt. They have a high concentration of urea in their blood, which is just right to maintain a high osmotic pressure in the body. This reduces the infiltration of salts from seawater, which accelerates the excretion of salts by the kidneys.

As a result, the meat of the fish will never become salty.

Difference Between Marine Fish and Freshwater Fish

Freshwater fish are fish that can live in freshwater with a salinity of 3 parts per thousand. Marine fish are mainly fish that live in the sea, such as hairtail, yellow croaker, etc. Freshwater fish are mostly herbivorous and omnivorous, and a small number are carnivorous. Marine fish, on the other hand, feed on a variety of flora, fauna and microorganisms in the ocean.

Another difference between marine fish and freshwater fish is that marine fish taste better than freshwater fish. This is mainly because the marine fish grow in the sea, and the swimming range and swimming force are very large, so the muscles of the sea water are more elastic and the taste is more delicious. In addition, freshwater fish mainly feed on saprophytes in the river, and the swimming range is also small, and the freshwater fish still have an earthy smell, so the taste of marine fish is better.

The meat of marine fish is not salty, because the fish in the ocean have their own "desalination", and the gills of bony fish in the ocean have "chlorine cells", which excrete chloride, the main component of seawater salt, from the body in the form of chloride. Cartilaginous fish in the ocean, which use the action of urea in the body to remove salt. Urea allows cartilaginous fish to maintain a high tonic pressure of body fluids, reduces the penetration of water into seawater, and also accelerates the excretion of salt in the body.

The meat of most marine fish is salty because the environment in which marine fish live is highly salty. So it must be a salty one. But the ocean fish will be a little fresher.

The fish of marine fish is not salty, it is the same as our normal fish, so it is necessary to put salt when stewing fish.

Marine fish are not salty because of the lack of meat, such as hairtail, which is not salty.

The meat of seafood fish is not very salty. The fish in the ocean have their own desalinators, which can drain the salt water they drink in time. And this desalination is different between bony fish and cartilaginous fish, but the effect is the same, so marine fish are not salty.

Marine fish do not have a salty taste, and bony fish living in the ocean have a strong ability to excrete salt, in addition to their kidneys to excrete a small part of salt, they also have specialized salt-excreting organs, that is, chlorine-secreting cells located in the gill sheets. Chlorine cells are like a desalination workshop that can desalinate seawater with high efficiency.

Due to the high fluidity and salinity of seawater, fish living in the sea are less likely to be infected with parasites, while freshwater fish are much more likely to be infected with parasites.

Problem description: Does it taste salty?

If not salty. So why isn't it salty?

Analysis: Why doesn't marine fish taste salty?

The sea water is salty and has a bitter taste, so it is not edible. But the fish that live in the ocean are not salty, why is that? It turns out that bony fishes in the ocean have a strong ability to excrete salt, and they have specialized organs for salt excretion, which are located in gill sheets and are composed of "chlorine secreting cells".

These "chlorine-secreting cells" are like a desalination workshop that can desalinate seawater, and the efficiency is so high that even the most advanced seawater desalination invented by mankind cannot be reached. In addition, in order to compensate for the loss of water in the body, marine bony fish also take measures to drink more water and less urinary urine to maintain hypotonic pressure in the body.

Cartilaginous fish, such as sharks and rays, do so in a different way. They don't drink seawater like bony fish, but they have a great ability to maintain a balance of osmotic pressure inside and out. They have a lot of urea in their blood, so the concentration of fluid in their bodies is higher than that of seawater, which forces them to urinate to remove excess water that seeps into their bodies.

Sometimes when we eat sharks, we always feel that there is a general pungent smell, and the reason for this is that sharks contain urea in their bodies. Urea can not only maintain the hyperosmolar pressure of body fluids in cartilaginous fish and reduce salt infiltration, but also play a role in accelerating salt excretion.

Not all the fish in the Hai Hui group are salty.

For example, bony fish in the ocean have a strong ability to excrete salt, and they have specialized organs for salt excretion, which are located in gill sheets and are composed of "chlorine-secreting cells". "Chlorine cells" can desalinate seawater with high efficiency. In order to make up for the loss of water in the body, marine bony fish also take measures to drink more water and less urinary to maintain low tonic pressure in the body.

Cartilaginous fish, such as sharks and rays, contain a lot of urine pyrin in their blood, so the concentration of orange in the body fluid is higher than that of seawater, forcing them to urinate to eliminate excess water that has seeped into their bodies. Urea can not only maintain the hyperosmolar pressure of body fluids in cartilaginous fish, reduce salt infiltration, but also accelerate salt excretion.
