Are you afraid of picking fish?Eat "spiny fish" or is about to become a reality

Are you still worrying about the fishbone stuck? Are you still afraid to eat fish because you are afraid of the fishbone? good news! good news! The major breakthrough in colleges and universities, the first wave of thorns -free fish has been successfully studied! Eating fish stabbing may become history, and finally you can eat fish!

The fish is tender and delicious and rich in nutrition, but the existence of the fishbone has dismissed waves of diners. Not only is the foreigners who do not make chopsticks, but also the native Chinese, there are also a lot of stabbing to eat fish. However, there was a good news recently. The team of Huazhong Agricultural University successfully found the gene to control the fishbone and cultivated the first generation of "less stab fish". With the deepening of the research, it is not impossible to cultivate "no thorn fish" in the future. For friends who like to eat fish and are afraid of fishbone, this is simply good news.

What is the use of fish thorns?

Speaking of "fishbone", everyone's first reaction must be "easy to stuck throat". They are thin and sharp, not only difficult to remove, but also easy to get stuck in their throats. If they are not handled in time, they may cause serious consequences. Like us humans, fish also belong to vertebrates. The bones of fish include skulls, spine bones, and attachment bones. Generally speaking, these fish bones are relatively difficult to get stuck in their throats (of course, it depends on the size of the fish bone and eating method). The most crazy and thin fishbone is hidden in the fish. Its formal name is called muscle bone (muscle thorns). The "fishbone" here refers to the muscle bone. Most of the fishes with muscle bones are often exposed to the carp family in fresh water.

The muscle bone is not the spine and the main bones used by fish for swimming, but a small thorns that grow in the muscles. As for why fish have muscle bones, the scientific community has no conclusion. However, scientists have found that in the simplicity of fish from simple to complex evolution, the muscle bone increases first, and then decreases. When it evolves to a certain stage, it will completely disappear. Therefore, scientists believe that muscle bones are used to support relatively loose muscles.

The fishbone is small, thin, and sharp, and it is easy to get stuck in people's throat, and this is why some people like to eat fish but are afraid of the fishbone. Some friends think that since there is a thorn, just pick it off? However, in addition to direct consumption, the fishbone has another negative effect, which is to cause trouble for large -scale production. After all, these muscles that are not thicker than needles are almost 100 % removed on the assembly line. Therefore, "eating fish without stabbing" has always been the dream of many lazy people when facing delicious fresh fish. Now, it may become a reality, and "no stab fish" may be able to board your table.

How to develop without thorn fish?

So how did the thorny fish develop? From the method of gene editing, the fish "remove the thorns" is about four steps: finding fishbone gene-find the "valid" gene-discover the "thorns" gene-obtaining thorns-free fish.

First of all, the researchers should pick out all the fishbone of a fish, degrade it, extract the RNA in the fishbone, and find the gene molecule expression of the fishbone. RNA is the abbreviation of ribosic acid and the carrier of genetic information. Unlike DNA, RNA is mainly distributed in the cytoplasm of biological cells and presents a single spiral structure.

After finding these genes in the fishbone, scientists use gene editing technology to conduct experiments on them one by one, and finally find a "effective" gene that can affect the growth of fishbone. This process is very long, and each test is a re -start. The research team edited about 40 genes. After 7 years of research, it finally found a "effective" gene that affects the fishbone in 2018. This gene can reduce 70%of the fishbone. Although it has not achieved the goal of "no thorn", it has also brought great encouragement to the entire team.

In the end, in 2019, in 2019, in the aspect of research leader Gao Zexia, "Suddenly suddenly", the "main effect" gene affects the "main effect" gene of the fishbone. This gene can reduce the 100%fishbone to truly achieve the goal of "thorns". After several generations of breeding, the taste of fishlessness is also very stable. After the measurement, although the fishbone changes, the nutritional components in the fish are not very different. In other words, there are less fish thorns, but the fish has not changed.

Although this technology has been successful, further verification is still required. At present, the team of Academician Gui Jianfang, the Institute of Aquatic Institute of Gao Zexia and the Chinese Academy of Sciences. It is believed that after generation of cultivation, the transformation from less stabbing fish to thorns -free fish will definitely succeed, and the real stabbing fish is expected to be on the table of ordinary families.

What are the few fish with less natural thorns?

Of course, it is necessary to go through the market for a long time to really enter the market. Is there any natural thorns in nature?

The answer is yes. The existence of fish thorns in different fish is different, and there are many muscle bones such as low -class bone fish. The catfish are fish with more fishbone.

If you are really too lazy to pick up, what fish should you choose?In fact, there are many edible fish to choose from, such as sea bass -shaped fish, such as sea bass, grouper, real sea bream, large and small yellow croaker, and so on.

Most scholars believe that the muscles of these fish are relatively compact and no longer require the support of the muscle bone, so the muscle bone is less or completely disappeared.In addition, some seafish's fishbone is relatively small and relatively neat, such as fish, cod, and biochemical fish.For friends who do not want to pick up, these fish are also good choices.
