Review
Antarctica has no one to settle, but there has never been a shortage of heat, and researchers from all over the world are very concerned, such as the United States, Britain, Russia, and China, who have set up scientific research stations here to carry out scientific research activities.
The discovery of Antarctic krill has once again aroused people's attention, and even there has been a scramble between countries.
What is Antarctic Krill?
Hearing the name Antarctic krill, many people may think that it is a kind of shrimp, but it is not.
Antarctic krill belongs to the krill class, and its appearance is different from the shrimp eaten in life, it is transparent throughout and emits light in the deep sea.
Krill, a marine species, has a wide range of distribution, but it is most abundant in Antarctica, with about hundreds of millions of tons detected so far, and this number may increase in the future. Many economically valuable fish feed on krill, which is also a key target for human fishing, and even has the reputation of "the food bank of the world's future".
Antarctic krill is similar in appearance to shrimp, but it is an invertebrate, like to live in groups, up to 10,000-30,000 krill per cubic meter, "population density" must be said to be very high.
What do they feed on? This is similar to shrimp, which also use a large number of plankton as prey objects to obtain survival energy. Their shape is similar to that of the shrimp we eat, and the adult individual can reach 6 centimeters in length and can live for about 6 years.
Do not underestimate these small invertebrates, which play an irreplaceable role in the stability and health of the Antarctic ecosystem.
Looking around the Arctic Ocean, antarctic krill is the key to energy transfer between lower and higher animals, and in the cute penguins and seals that feed on them, without Antarctic krill, Antarctic biodiversity will encounter great difficulties.
Antarctic krill compete for the storm
Antarctic krill is mainly distributed in the rarely populated Antarctica, and it is gradually known with Antarctic scientific research. However, due to the cold weather in Antarctica, there are extreme days and nights, thin oxygen and other conditions, large-scale fishing activities have only begun in the 1960s and 1970s.
The first major fishing household to appear, the Soviet Union deserved it.
The climatic conditions of the Soviet Union itself were very similar to those of Antarctica, and the Soviet Union was strong at that time, and the fishing technology in the coastal areas was relatively advanced, so it was not too difficult to enter the Antarctic for fishing.
In the first few years of fishing, the Soviet Union harvested a full harvest, no one can compare, however, after the collapse of the 90s, its national strength suffered great damage, domestic affairs were overwhelmed, the throne of the big brother of shrimp fishing, it was changed.
Coastal countries such as Japan and Norway have all competed to become the leading countries in Antarctic krill fishing during this time. Japan is not only famous for whaling, but also antarctic krill fishing.
At present, Norway is the most developed country in the world's shrimp fishery, and their annual shrimp catch can account for half of the world's total, which is shocking, which is of course related to its geographical environment.
We in China should not be underestimated.
Although we did not show much performance in the shrimp fishing war in the last century, with the progress of science and technology and social and economic development in our country, the country has paid more and more attention to the development and research of Antarctic resources.
In recent years, the mainland has independently developed fishing boats, as well as icebreakers, built a new Antarctic station, and also emerged in Antarctic krill fishing, fishing activities have become more and more efficient, and it is expected to overtake in curves and lead the world.
Why are the great powers scrambling for Antarctic krill?
What's so good about Antarctic krill? Why are the great powers rushing into Antarctica to scramble?
First of all, Antarctica is a borderless land, which needs to be developed urgently, and various countries pay close attention to various resources here, and the scientific research value is very high; And it's a free thing.
Second, Antarctic krill itself has economic value, it can become a potential food for mankind in the future, and it also has a huge shallow energy in medicine.
In terms of nutrition, Antarctic krill is rich in high protein, but the fat is very low, and in addition to the first time, it is rich in minerals, which is higher than the nutritional value of Japanese shrimp, clams, etc. Antarctic krill is very friendly to people with high cholesterol, its sterol content is only 4%-7%, and the vast majority of sterols are cholesterol.
In addition, scientists have also found a variety of active substances in Antarctic krill, such as protein-digesting enzymes.
In terms of medical value, Antarctic krill is even more surprising. People's economic conditions are better, more and more attention is paid to health, the medical industry has been greatly developed, and drugs are the basis for the development of medicine.
Antarctic krill, like other crustaceans, contains a lot of chitin, but other animals, difficult to extract, Antarctic krill shell is almost transparent, very thin, which greatly facilitates researchers, the extraction of chitin. Medicine has achieved industrialization, and it is inevitable to pursue efficiency and profit.
The reason why chitin is so popular is because it has several medical functions that concern everyone, first of all, it can enhance immunity, and the most basic thing for people to maintain a healthy body is to increase their own resistance. Drugs are only auxiliary, not dependent, and now the problem of drug resistance is so serious.
Secondly, it can fight cancer, since entering modern times, people are almost talking about cancer discoloration, there are still many cancers that are incurable diseases, leaving patients and families with only endless pain, which is also one of the motivations for anti-cancer drugs and foods to be highly sought after.
Finally, the improvement of modern quality of life has also brought new health troubles to people, and the so-called rich diseases such as high cholesterol, high blood pressure, and high blood sugar have appeared, and the components in Antarctic krill have a certain effect on reducing these indicators.
The edible value and medical value of Antarctic krill are still under further development, all in all, Antarctic krill is a treasure trove of nutrition and medicinal uses.
epilogue
Antarctic krill is not only a gift from nature to the Antarctic biosphere, but also to the world. Our country attaches more and more importance to the scientific research and development of Antarctica and explores Antarctica for peaceful purposes.
