Review
At both ends of the planet, there are north and south poles that are cold all year round. These two places are places with almost no permanent population in the world, so the north and south poles are also known as "the last pure land in the world".
Without human interference, there are extremely rich ecological resources living here. As early as the 18th century, people found a rich number of krill in Antarctica, and later, the number of Antarctic krill reached a staggering 1 billion tons.
In the face of such abundant food resources, the countries of the world are also extremely fierce competition for this, which congress is the final winner?
Why is Antarctica so rich in krill resources?
Before the in-depth understanding of Antarctica, humans had always thought that this was just a barren "ice and snow world". Because in the Antarctic, it is cold all year round, so when we come to the Antarctic region, all we can see is white ice and snow.
But it is precisely under these snow and ice that there are actually extremely abundant ecological resources, which are represented by krill resources. Krill are known as "ocean grains" and are extremely nutritious. Although it is not large, it is an important organism in the Antarctic basic ecosystem and the main food provided to higher organisms in the ocean.
Therefore, the status of Antarctic krill in the Earth's marine biosphere is essentially very important.
According to statistics, if the krill in the Antarctic region is gathered, it is likely that the density can reach 30,000 per cubic meter. At present, the world's capture of Antarctic krill is even certain to reach 100 million tons to 150 million tons a year, which is more than twice the total krill catch in the world.
It can be seen that the number of krill in the Antarctic region is far beyond people's imagination.
So, why is there such a rich krill resource in the Antarctic region?
First of all, this has to do with the viability of krill itself. As the main organism in antarctic waters, krill can reach such a large number of scales as it is now, which is actually greatly related to krill itself.
Female krill themselves can reach 6,000 to 10,000 eggs per spawn, and these krill eggs can generally be successfully hatched within 3 to 5 days, so the annual reproduction of krill is actually extremely large.
Coupled with the krill's own super adaptability to the environment, krill can successfully survive in the cold Antarctic waters all year round. According to the research data, even in the absence of any food, krill can successfully survive for nearly 200 days.
Second, the impact of the Antarctic Current. Near the South Pole, there is currently the strongest Antarctic Anipolar Current in the world. These powerful ocean currents flow around the Antarctic Sea, allowing nutrient resources in the Antarctic Sea to be continuously carried above the sea.
In this way, it can bring extremely rich nutrients to the Antarctic basin. For Antarctic krill, the food requirements are not so high, so these nutrients can also help them survive successfully in Antarctic waters. Therefore, in Antarctic waters, there is no shortage of Food for Antarctic Krill.
Without human intervention, the annual reproduction of Antarctic krill is undoubtedly huge under natural conditions. Therefore, on the earth, there are also extremely rich krill resources.
Competition for krill resources in various countries
In our cognition, potatoes, wheat, etc. are crops that we often use as food, and the nutritional value is relatively rich. But in the face of Antarctic krill, these crops can be easily "defeated".
Krill itself is extremely rich in protein resources and very low in fat. At the same time, "krill oil" also has the magical function of "reducing the three highs", which can provide extremely rich nutritional value to the human body.
Therefore, krill is undoubtedly a "biological treasure" for humans. After countries recognized the value of krill, they launched a "battle for contention" against it.
As early as the 1960s, the then world power, the Soviet Union, was the first to fish for krill. At that time, the Soviet Union recorded 500,000 tons of krill catches in a year, accounting for more than 80% of the world's krill catch at that time.
Later, with the collapse of the Soviet Union, Japan followed suit and occupied the top spot in krill fishing. During the years that Japan dominated krill fishing, although the overall catch was not as large as that of the Soviet Union, the total catch was still extremely large.
Later, as the equipment of Japanese ships deteriorated, Norway took over the Seat of Japan, increasing the krill catch at that time by a lot.
It can be seen that the world's competition for krill resources has never stopped.
Why is China the biggest beneficiary?
At present, as a world power, China has naturally not given up the competition for krill resources. And in the krill fishing activities, China has also become the biggest beneficiary, what is going on?
In fact, in the very beginning, because of the backward fishing equipment at that time, the mainland did not have an advantage in the Antarctic krill battle.
However, with the subsequent development of mainland science and technology, the mainland successfully produced advanced fishing equipment such as the "Deep Blue", becoming one of the most competitive fishing vessels in the world at that time.
The Deep Blue ocean fishing vessel
In the future, the mainland also plans to design the "Antarctic" ship to enhance the exploration of the Antarctic region.
Up to now, the continent's Antarctic krill catch has been able to stabilize at more than 100,000 tons per year, becoming the only country that is the second "hegemon" Norway. It is believed that in the future, the mainland will also be able to improve the krill fishing industry chain and become the "fishing hegemon" in the world.
The fishing of Antarctic krill has brought abundant food resources to the mainland, and since the continent is currently the most populous country in the world, China is also the country that benefits the most in a sense.
epilogue
In the future, with the continuous development of human technology, we also believe that more biological resources will be found in the Antarctic region.
