My Deep-sea Fishery

Xiang Yang was in a very good mood without encountering the terrifying murderous wind of Antarctica.

At exactly this time, Xiang Yang saw the seal, huddling with the crew at the door of the cabin, sticking his head out of the crowd, looking at the outside of the cabin eagerly.

Xiang Yang couldn't help but laughed, "What's the matter with this seal, why did he even ran into the cabin?"

"Brother Yang, I brought it in. Didn't you just say it was going to blow a snowstorm? I want to save him." Fang Youqun said.

"It doesn't need you to save it." Xiang Yang shook his head.

In the Antarctic region, for humans and even for penguins, a blizzard is an extremely terrifying disaster, but for the seals, a blizzard is really nothing. Even the colder they are, the more excited they are. Thick fur, without fear of any wind and snow.

Seeing that the danger was lifted, the crew members who had survived the catastrophe became interested in the cute harp seal, and many people began to tease it.

"This harp seal is so cute. It's much cuter than other leopard seals. Captain, can we keep it?" a crew member asked Xiang Yang.

The crew knew that Xiang Yang liked these spiritual marine creatures, otherwise, no matter how cute this seal is, they would not ask such questions.

However, this seal is indeed very cute and well-behaved. He stayed in the middle of a group of crew members, supported his body with his two forelimbs, and his two black eyeballs were turning round and round.

Xiang Yang actually liked this seal very much, but Xiang Yang still shook his head and said: "No, our ship cannot stay in the Antarctic forever. After leaving the Antarctic, this seal is not so easy to feed."

In fact, seals are relatively easy to feed, even without sea water, fresh water can feed them.

Two seals were raised artificially in Baotu Spring Scenic Area in Jinan, my country.

The controversy about freshwater culture of seals is a bit big.

But as to whether fresh water can raise seals, the answer is yes.

What determines whether organisms can survive in fresh water is whether they can stabilize the osmotic pressure of the body.

In the process of tens of millions of years of biological evolution, seals, sea lions and other pinnipeds have gone through the evolution process from land to the ocean, so unlike fish, they can survive in both seawater and freshwater.

In the 1980s, my country had a record of survival of harbor seals breeding in freshwater environments. However, due to the difference in the composition of seawater and freshwater, seals that have lived in freshwater for a long time are prone to eye diseases, and therefore require veterinarian care and careful control of water quality.

Moreover, the seal is a second-class protected animal in my country. Although other countries kill about 100,000 harp seals every year, in our country, private individuals are not allowed to raise them, let alone kill them. If they are raised dead, they are definitely asking themselves. Trouble, Xiang Yang didn't want to ask for trouble.

"Don't surround this seal, you guys, this seal has a lot of bacteria, don't get infected." Xiang Yang saw that the crew was crowded next to the seal, the game crew even wanted to reach out and touch it, and said quickly. Reminded.

Upon Xiang Yang's reminder, the crew immediately discovered something was wrong.

I saw Xia Pengjie clutching his nose and frowning, "This harp seal's mouth smells so bad."

Several crew members nearby sniffed, and immediately smelt them, and hurriedly covered their noses with their hands.

Xiang Yang shrugged his shoulders, "This is too normal. The harp seal also likes to bite a hole on the ice, and then dive through the hole. It is estimated that its teeth and gums have long been bitten, and the bacteria in the mouth are very serious. Many, so you all stay away from it and don't be bitten by it."

"Let me see." Fang Youqun walked over at this moment, he squatted down and looked at the harp seal's mouth.

Just then, the harp seal yawned, showing its rotten teeth.

"Really, almost all of its teeth are melted away, Brother Yang, how about we keep this seal, how can it forage under the water like this?" Fang Youqun said distressedly.

"This." Xiang Yang hesitated for a moment, "You can let it stay on the boat for a while, clean up the wound in its mouth, and then send it to the rescue station, or put it back into the sea after its injury is better. , Absolutely cannot be taken back."

The crew nodded quickly.

Soon, the doctor accompanying the ship gave the harp seal anesthetic.

After the harp seal passed out, he immediately used medical cotton to clean the wounds and rotten meat in his mouth, and then cleaned it with spirits.

"I have cleaned the wound, but the teeth can't help it unless you bring it with braces, or directly implant teeth for it." The accompanying doctor said.

Of course Xiang Yang couldn't put braces on this harp seal.

As for implanting teeth, this professional term Xiangyang Ting is the first time to listen, let alone implement it.

Helpless, Xiang Yang had no choice but to say: "Let’s do this first. After it wakes up, feed it some krill, and then clean up its wound again tomorrow. As long as it doesn’t bite the ice, then this harp seal It's almost healed."

The crew felt a little sorry.

In fact, Xiang Yang was also sighing inside.

It is the nature of seals to bite the ice cave. As long as it lives in the wild, how could this harp seal not bite the ice cave?

Fang Youqun said with some pity, "Brother Yang, his teeth are all flattened out, so how can he eat?"

"Don't worry, you only need to give it the Antarctic krill, it will definitely have a way to eat it." Xiang Yang said.

After the rotten meat in the mouth of this harp seal was cleaned up, the very unpleasant odor disappeared immediately.

Xiang Yang squatted down and gently rubbed the head of the harp seal.

Although the vast majority of Antarctic krill live on the surface of the sea within 50 meters ~ www.readwn.com ~ and there are a lot of them.

But the seals have small mouths, unlike whales that can swallow massive amounts of Antarctic krill in one bite.

Therefore, in nature, it is difficult for seals to feed themselves just by devouring krill. They have to go to deeper sea areas to prey on some slightly larger cold-water fishes.

In fact, Antarctic krill is also a very delicate marine creature. Although there are many in number, its vitality is not tenacious at all.

In the aquarium, Antarctic krill will even eat each other's companions.

When Antarctic krill are not fed in the aquarium, they will shed their shells and shrink in size, which other animals do not have. Scientists speculate that this may be an adaptation of Antarctic krill to food supply restrictions in winter.

The water temperature of the Southern Ocean is low all year round, and the salinity has not changed greatly. There is no interference from other factors such as rivers and people. Such a stable environment makes the krill become tender, poor adaptability, and cannot adapt to slight changes in the environment.
