Can be used as food.

Compared with wheat and rice, the nutritional content of Antarctic krill is quite high.

The protein content in krill exceeds 50%, which is higher than any current food. Krill is also rich in vitamin A, astaxanthin and other ingredients, which are very beneficial to the human body.

Scientists have always hoped to develop Antarctic krill resources and regard krill as mankind's "future food".

Scientists estimate that the total mass of krill living in the Antarctic region alone is 5 billion tons.

In other words, if humans stopped eating food and only ate krill, they would be able to meet the food needs of a population of 7 billion.

Many people like to eat shrimp, which is not only delicious but also has extremely high nutritional value. Shrimp contains 20% protein, which is several to dozens of times more than fish, eggs, and milk.

Among shrimps, krill is the organism with the highest protein content that has been found, reaching more than 50%. The nutritional value of one krill is equivalent to 200 grams of barbecue. Not only that, krill is also rich in amino acids and

Vitamin A.

Since the nutritional value of krill is so high, it will eventually be served on people's tables.

Chinese foodies have also invented delicious recipes such as Jinzhiyuye, Jinwuzangjiao, Jinyu Mantang, etc.

People catch large amounts of Antarctic krill every year, and it is also the main food for baleen whales and some commercial fish.

According to online rumors, nearly 300 million tons of Antarctic krill are eaten every year. Just one adult blue whale can eat 4 tons in a day. Add in human capture and other animal predation, how much Antarctic krill can be produced in a year?

How can we consume so much?

300 million tons, this number is astonishing. You must know that an Antarctic krill weighs only about 2 grams and is 45-60 mm long.

But the amazing thing is, even though so many Antarctic krill are eaten every year, why do they always maintain a safe number and never become extinct?

Antarctic krill, a crustacean zooplankton that lives in the Southern Ocean, lives in colonies, sometimes with a colony density of 10,000-30,000 per cubic meter.

Antarctic krill also have bioluminescent organs that produce light.

These organs are distributed in different parts of the Antarctic krill and emit yellow-green light every 2-3 seconds.

Don't underestimate these built-in lights, they can be compared with flashlights.

However, the function of these lights is still unknown. Some people hypothesize that these lights are used to cover the shadow of Antarctic krill and "invisible" from predators.

It is said that the reserves of Antarctic krill are astonishing, about 400-600 million tons. There is also an exaggerated statement on the Internet that it is 5 billion tons.

If this is the case, then how powerful the reproductive capacity must be! In fact, there are several reasons why Antarctic krill is so durable: First, Antarctic krill has extremely strong reproductive capacity.

The main spawning season for Antarctic krill is from January to March, with females laying 6,000 to 10,000 eggs each time.

After the krill eggs are discharged into the water, they continue to sink before they hatch. They hatch as they sink, and continue to sink to hundreds of meters.

It took even more than 3,000 meters for the larvae to hatch.

The larvae continue to float up during the development process, and develop as they float. When the larvae develops into the shrimp stage, it has almost reached the surface of the sea water.

At this time, it can feed, grow, and swarm on the surface.

When it matures, it reproduces to the next generation.

Generally speaking, the maturity period for Antarctic krill is two years.

Krill that grow for one year can grow to 2 to 3 centimeters long. When they mature in the second year, they are 5 to 7 centimeters long, and they are ready for fishing.

The second is large numbers, plenty of food, and good living environment.

Antarctic krill mainly feed on phytoplankton, similar to seaweed, small zooplankton, copepods, amphipods, etc. There are a lot of algae in the ocean, and the rich seaweed resources are

Krill provide a good living environment, and with these favorable conditions, the number of krill will of course remain in a balanced state.

It is precisely because of these innate favorable conditions that the Antarctic krill transmitted online have never become extinct despite eating 3 tons a year.

Scientific research shows that Antarctic krill is rich in high-quality protein and a wide variety of unsaturated fatty acids.

After analysis, it was found that Antarctic krill contains all the amino acids necessary for the human body, especially the content of lysine, which represents nutritional characteristics, is higher than tuna, tiger shrimp and beef.

In addition, Antarctic krill also contains a large amount of nutritional metal elements, such as calcium, phosphorus, potassium, sodium, etc. needed by the human body, and its eyeballs are also rich in carotene.

In addition to these nutrients, Antarctic krill is also high in glutamic acid, mencoline, glycine, alanine, serine and threonine, which give umami and sweet tastes.

Therefore, Antarctic krill is not only nutritious, but also tastes sweet and tender, making it very suitable for meals for the elderly and children.

In recent years, the concept of "Internet +" has continued to deepen, and people's consumption concepts have also quietly changed.

Consumers are no longer attracted by discounts and promotions, but are more willing to pay for quality and service.

Antarctic krill is an inevitable product that conforms to the trend of the times. It is a high-quality healthy food ingredient that conforms to the consumption concept of the new era.
