My Deep-sea Fishery

This is also one of the important reasons why Xiang Yang is resolutely unwilling to bring this harp seal back.

Harp seals that are accustomed to Antarctic krill and other cold-water fishes are almost impossible to feed after taking them home.

After all, after leaving the Antarctic, Xiang Yang couldn't get the krill for this harp seal.

The adult krill is only suitable for living in high temperature and low salt waters. Its suitable temperature range is only 0.64 degrees Celsius to 1.32 degrees Celsius. If the temperature is higher than 1.80 degrees Celsius, it may bring it fatal danger.

Therefore, Antarctic krill is only suitable for living in the relatively cold waters around Antarctica, and there is no trace of Antarctic krill in the sea far away from Antarctica.

"Brother Yang, why don't we stop feeding him Antarctic krill this time, what do you think of giving him something better?" Fang Youqun asked suddenly.

Xiang Yang suddenly laughed, "Do you think Antarctic krill is not a nutritious seafood?"

In fact, the nutritional value of Antarctic krill is extremely high.

Although Antarctic krill is a shrimp, its shrimp shell is composed of crustaceans and insect shells.

Harp seals can use special enzymes to degrade chitin to obtain energy after preying on Antarctic krill.

In addition, Antarctic krill is also very precious to humans.

For example, disease control, prevention, and elimination rely on vaccines and chemotherapeutic substances, which all require the use of Antarctic krill.

Some diseases have not yet found effective treatments. For example, there are no clear and effective preventive and curative measures for diseases that occurred in the salmon farming industry in Chile and the diseases that have severely affected the shrimp farming industry around the world, but the shell of Antarctic krill can cure that disease.

In addition, Antarctic krill can also promote the ingestion of substances for the immune function of animals.

The shell material of Antarctic krill contains complex polysaccharides like chitosan.

Chitosan is a derivative of chitin, which is contained in the body of krill. Chitosan can be used as an immunostimulant for salmon and trout by adding it to feed or by injection. Chitin is proven to be a stimulant for many organisms to enhance the immune system, and krill is one of the sources of chitin.

Someone once did an experiment where Antarctic krill was used to feed ordinary shrimp.

In the experiment, the feed added with krill can greatly enhance the growth rate of shrimp.

In addition, studies have also shown that adding krill to salmon and trout feed can directly promote the health of their spawning and reproduction of offspring, reducing mortality and true pathogens.

Other applications of krill include capsule food for juvenile shrimp and prawns, special ingredients for feeding marine and tropical fish, and as a food attractant to increase food intake.

In addition, Antarctic krill can also be made into dried Antarctic krill.

Dried Antarctic krill is made up of selected high-quality precious live shrimps that grow in the cold waters of Antarctica without any pollution. They are real green food. It plays an important role in the Southern Ocean food chain, including seals, whales, penguins and various fishes. The food is also an important marine biological resource.

Antarctic krill dried shrimp is processed by freshly harvested krill within 1 to 5 hours, and processed by freezing and vacuum drying under aseptic conditions.

Dried Antarctic krill fully retains the rich nutrients and deliciousness of the shrimp.

As dried Antarctic krill and shrimp are pure natural substances without any additives, it is still the top fish feed. Fish are easy to absorb. The enzymes contained in krill promote the digestion of fish, and the water quality can be kept clean for a long time.

Xiang Yang said all this.

Fang Youqun was immediately stunned, "Can these Antarctic krill that are everywhere be so precious?"

"Price parity does not mean that there is no good product. After all, what the market emphasizes is that a thing is rare and expensive. Once there were many yellow croakers, it was very cheap. Look at the current price of yellow croaker." Xiang Yang smiled.

It can be said that the shell of Antarctic krill will produce a substance harmful to the human body after death, and it is definitely a first-class aquatic product.

Fang Youqun nodded quickly, "Okay, then we will feed it Antarctic krill these few days."

"Well, that's it, get a bigger water tank, put a few large ice cubes in it, let it stay in the water tank first, and then clean the wound twice, and wait for its wound to grow new meat. , This seal is safe." Xiang Yang said with a smile.

It's the nature of seals to bite ice, but if their teeth are gone, naturally they can't bite anymore.

After this harp seal is well wounded, it is nothing more than a little more difficult to hunt. Fortunately, there are so many Antarctic krill in this sea area that it can never starve to death.

Although the crew members were very reluctant to bear this poor and cute seal, Xiang Yang had already spoken, so naturally they did not dare to object.

Gao Chuang saw the end from the beginning, and he said in amazement: "This is the first time I have seen someone catch a harp seal and will release it again. Do you know how much its fur is worth?"

Xiang Yang smiled, "Mr. Gao, let's stop discussing this. Harp seals are counted among all the seals, but even so, there are not many of them now. These are all species that are about to become extinct. , Just let them go."

"It was your people who arrested it anyway, so you can do whatever you want." Gao Chuang said casually.

Then Gao Chuang tightened the winter clothes on his body and looked at the sky anxiously and said: "How do I feel that the snow is getting bigger and bigger, but don't freeze the whole sea for me, then we can see that it is really troublesome."

"Isn't there an icebreaker?" Fang Youqun questioned.

"The role of the icebreaker is to allow us to clean up some ice-bound sections of the channel. It is not directly letting us sail on the ice, nor is it a nuclear-powered icebreaker." Gao Chuang said helplessly.

The reason why these icebreakers have gradually changed from scientific research to civilian use, and some have even been transformed into tourist boats, is that they have been eliminated by scientific research laboratories.

Nowadays, in countries with strong national power, almost all icebreakers used in Antarctica are nuclear-powered. UU reading www.uukanshu. com

Xiang Yang smiled and said, "Don't worry, if it were to freeze, this sea area would have been frozen long ago, and there is no need to wait until now."

"I hope so." Gao Chuang said anxiously.

Xiang Yang smiled and didn't speak. In Xiang Yang's view, this was an ordinary snowfall at best. As long as there was no blizzard, a little snow would pose no threat to Xiang Yang.

However, the temperature became colder due to heavy snowfall in the sky.

Xiang Yang was wearing thick winter clothes, and he still felt that his hands and feet were starting to become cold, and his face was flushed with cold.

"Let's eat Antarctic krill later." Xiang Yang suggested.

Antarctic krill contains various nutritional metal elements, such as calcium, phosphorus, potassium, sodium, etc., which are needed by the human body.

In addition, the eyeballs of krill are also rich in carotene, eating a little bit is helpful for keeping out the cold.
