Many people like to eat shrimp, which is not only delicious, but also extremely nutritious. Shrimp contains 20% protein, which is several times to dozens of times that of fish, eggs and milk. Among shrimps, krill is the organism with the highest content in protein, accounting for more than 50%. The nutritional value of a krill is equivalent to 200 grams of barbecue. Not only that, krill is also rich in amino acids and vitamin A. Since krill has such high nutritional value, it naturally comes to people's table at last. China gourmets also invented a delicious way to eat, with golden branches and jade leaves, and the golden house hides the charming, and they have been happy ever since.
People catch a large number of Antarctic krill every year, which is also the main bait for baleen whales and some economic fish. According to the Internet, Antarctic krill is eaten nearly 300 million tons every year, and only one adult blue whale can eat 4 tons a day. Coupled with human capture and predation by other animals, how many Antarctic krill can be produced a year to be consumed like this? 300 million tons, this figure is amazing, you know, an Antarctic krill only weighs about 2 grams and is 45-60 mm long. But surprisingly, even though Antarctic krill is eaten so much every year, why does it always keep a safe quantity and will never become extinct?
Antarctic krill, a crustacean zooplankton living in the southern ocean, lives in groups, and sometimes the population density reaches 0/0000-30000 per cubic meter. Antarctic krill also has bioluminescent organs that can emit light. These organs are distributed in different parts of Antarctic krill and emit yellow-green light every 2-3 seconds. Don't underestimate these self-contained lamps, which can be compared with flashlights. However, the function of these lights is still unknown, and some people have put forward the hypothesis that these lights are used to hide the shadow of Antarctic krill and are "invisible" to hunters.
It is said that the Antarctic krill reserves are amazing, about 400-600 million tons, and there are also exaggerated statements on the Internet, with 5 billion tons. If so, how powerful the reproductive capacity must be!
In fact, Antarctic krill is very resistant to eating for the following reasons:
First of all, Antarctic krill is extremely fertile. The main spawning period of Antarctic krill is 65438+ 10 to March of the following year, and the females will lay 6000 eggs each time. 10000 eggs. After the krill eggs are discharged into the water, before hatching, they continue to sink and hatch until they sink to hundreds of meters. Even more than 3000 meters, just hatched larvae. During the development process, the larvae keep floating, floating and developing. When the larvae develop into shrimp stage, they almost reach the surface of the sea. At this time, it can feed, grow and cluster on the surface. When it matures, it will reproduce in the next generation. Generally speaking, the maturity of Antarctic krill is two years. Krill that grows for one year can grow to 2 to 3 centimeters long, and it will be 5 to 7 centimeters long when it matures in the second year, so it can be caught.
Secondly, there are more quantities, more food and a good living environment. Antarctic krill mainly feeds on phytoplankton, similar to algae, micro-zooplankton, copepods, amphipods and so on. And there are many algae in the sea. Abundant algae resources provide a good living environment for krill. It is with these favorable conditions that the number of krill will of course remain in balance. It is precisely because of these innate advantages that the Antarctic krill transmitted by net does not eat 3 tons a year and has never been extinct.
Scientific research shows that Antarctic krill is rich in high-quality protein and a variety of unsaturated fatty acids. It is found that Antarctic krill contains all essential amino acids, especially lysine, which represents nutritional characteristics, higher than tuna, tiger shrimp and beef. In addition, Antarctic krill also contains a large number of nutrient metal elements, such as calcium, phosphorus, potassium, sodium and so on. Its eyeballs are rich in carotene. In addition to these nutrients, the contents of glutamic acid, aspartic acid, glycine, alanine, serine and threonine in Antarctic krill are also high. Therefore, Antarctic krill is not only nutritious, but also sweet and tender, which is very suitable for the diet of the elderly and children.
In recent years, internet plus? With the deepening of the concept, people's consumption concept is also quietly changing. Consumers no longer blindly follow the crowd? Discount? 、? A promotion? Attracted, but what would you rather do? Quality? 、? Service? Pay the bill. Antarctic krill is the inevitable product of this trend of the times, and it is a fine health food that conforms to the consumption concept of the new era. In order to maximize the nutrition of Antarctic krill, all Antarctic krill sold online are caught from Antarctic waters? In the hands of consumers, the whole process is transported in a strict cold chain state, and every link is traceable, thus achieving real significance? Antarctic direct? .
In the after-sales aspect, online shopping not only provides consumers with nearly 100 kinds of Antarctic krill recipes, but also guarantees all the defective products received by customers. The inner packaging of Antarctic krill is vacuum-treated, the main purpose of which is to facilitate transportation without affecting eating. But? Antarctic direct? Customers get an extra pack of Antarctic krill and a pack of Antarctic krill meat as compensation. Such thoughtful service has won unanimous praise from customers.
