Krill is a kind of shrimp living in the ocean, the Antarctic region is the most abundant in resources, especially underestimating this small shrimp rice, on the earth its reserves are more than all the total grain production in the world, in 2019 the world's total grain production is 2.722 billion tons, which includes wheat, barley, rice, corn, soybeans, mung beans, sorghum, millet, sweet potatoes, potatoes and other food crops, but the world's marine krill reserves are optimistically estimated at more than 10 billion tons, equivalent to 4 times the world's total food production, The krill resources in antarctica alone are optimistically estimated at about 5 billion tons, equivalent to twice the total global food production.
What is even more valuable is that krill is more nutritious than all of them, with a protein content of more than 50%, far more than any food crop, and the content of vitamin A and astaxanthin is also very high. Therefore, krill resources are considered to be of great development value, and are also known as "marine grain", "human future grain bank", "the largest protein bank on the earth" and so on.
Krill is a krill genus of krill in the arthropods, if we say that our common crayfish, prawns, lobsters, shrimp, etc. are the real shrimp, then krill actually does not belong to the shrimp, because krill belongs to the krill order, and lobsters, prawns, etc. belong to the order Oftes, it can be said that krill are cousins with them, but they are not a family.
Krill all live in the ocean, the world is known to have 85 kinds of krill, antarctic krill is the most famous, its body length is between 8 ~ 60 mm, the size is very small, in China's coastal areas there are more than 20 kinds, such as the Pacific krill is also an important marine fishery resources in China.
From understanding the value of marine krill resources, countries around the world are paying more and more attention to the acquisition and utilization of this marine resources, in the 1980s, the Soviet Union in antarctica every year to obtain 300,000 to 500,000 tons of krill, after the collapse of the Soviet Union fishing fell to about 100,000 tons, this year the Russian Fisheries Company will turn its attention back to the Antarctic krill, in early May, more than a dozen experts from the Russian Fisheries and Oceanographic Research Institute went to antarctic waters to investigate krill resources, ready to pave the way for large-scale fishing in the future. Its related aquatic enterprises are also preparing to obtain $640 million in krill resources this year.
In recent decades, countries around the world have recognized the potential value of Antarctic krill, and countries in the right place have begun to carve up this almost free cake. China has done far less in this regard, it can be said that the starting late catch is small, but China has also recognized the importance of krill resources to the future of food sources, food security and national nutrition access, in recent years at the national level has been attached importance, there are some local actions, such as In January this year, Shandong Province studied and formulated the Antarctic krill industry development plan, accelerated the construction of modern Antarctic krill professional fishing and processing vessels, and accelerated the construction of Antarctic krill resources comprehensive utilization industrial agglomeration area, etc. Gather national science and technology and policy support resources, and strengthen the support and utilization of krill industry development from different levels such as basic research, application and engineering development, regional demonstration, platform construction, and emerging industries.
At present, the international allowable catch of Antarctic krill is more than 6.2 million tons per year, and the number of krill eaten by blue whales, penguins, water birds and fish is more than 300 million tons per year, but the resources of Antarctic krill are still very rich, and even biologists believe that Antarctic krill is a bug in the biological chain of the earth.
This is mainly because of the strong reproductive ability of Antarctic krill, strong environmental adaptability, rich food sources and other reasons to promote, Antarctic krill although small, but female krill each time the amount of eggs up to 6000 to 10,000 grains, can be spawned many times a year, young shrimp grow to the stage of sexual maturity is also very fast, krill can adapt to the cold water environment, to water organic matter and plankton as food, it is easy to survive and grow, so although many organisms are feeding on it, human fishing for it is also increasing, However, the resources of Antarctic krill are still not reduced.
