My Deep-sea Fishery

Xiang Yang was in a great mood when he didn't encounter the terrifying murderous wind in Antarctica.

Just at this time, Xiang Yang saw the seal, which was huddled with the crew at the door of the cabin, stuck out its head in the crowd, and looked out of the cabin eagerly.

Xiang Yang couldn't help laughing, "What's the matter with this seal, why did it run into the cabin?"

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

"It doesn't need your help." Xiang Yang shook his head and said.

In the region of Antarctica, a snowstorm is a terrible disaster for humans and even penguins, but for seals, it is really nothing, and the colder they are, the more excited they are. Thick fur, no fear of any wind and snow.

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

"This harp seal is really cute, much cuter than that leopard seal, captain, can we keep it?" a crew member asked Xiang Yang.

The crew all knew that Xiang Yang liked these spiritual sea creatures very much, otherwise, no matter how cute this seal was, they would not have asked such questions.

However, this seal is really cute and obedient, staying in the middle of a group of crew members, supporting its body with its two forelimbs, and rolling its two black eyeballs.

Xiang Yang actually likes this seal very much, but Xiang Yang still shook his head and said: "No, our ship can't stay in Antarctica forever. After leaving Antarctica, this seal will not be so easy to feed."

In fact, seals are relatively easy to feed, and they don't even need seawater, fresh water can feed them.

In the Baotu Spring Scenic Spot in Jinan, my country, two seals were raised artificially.

There is a bit of controversy surrounding freshwater farmed seals.

But as to whether seals can be raised in fresh water, the answer is yes.

Whether organisms can survive in fresh water depends on whether they can stabilize the osmotic pressure of the body.

During tens of millions of years of biological evolution, pinnipeds such as seals and sea lions have undergone the evolution process from land to sea, so unlike fish, they can survive in both seawater and freshwater.

In the 1980s, my country already had a record of survival of spotted seals bred in freshwater environments. However, due to the difference in the composition of seawater and freshwater, seals living in freshwater for a long time are prone to eye diseases, so they need the careful care of veterinarians and the careful regulation of water quality.

Moreover, seals are a second-class protected animal in our 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 die, they will definitely ask for it Trouble, Xiang Yang doesn't want to ask for trouble.

"You guys, don't surround this seal. There are a lot of bacteria on this seal, so don't get infected." Seeing that the crew members were crowding around the seal, the game crew members even wanted to reach out to touch it, so he hurriedly said Remind.

After being reminded by Xiang Yang, some crew members immediately noticed something was wrong.

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

Several crew members nearby sniffed, and immediately smelled it, and quickly covered their noses with their hands.

Xiang Yang shrugged his shoulders, "This is quite normal. Harp seals also like to bite a hole on the ice, and then dive through the hole. Its teeth and gums must have been damaged long ago, and the bacteria in its mouth are very serious. There are many, so you all stay away from it, and don't be bitten by it."

"Let me see." At this time Fang Youqun walked over, he squatted down, and looked towards the mouth of the harp seal.

Just at this moment, the harp seal yawned, showing its rotten teeth.

"Really, almost all of its teeth have been worn away. Brother Yang, why don't we raise this seal, how can it forage for food underwater like this?" Fang Youqun said with some distress.

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

The crew nodded quickly.

Soon, the accompanying doctor on board gave the harp seal anesthesia.

After the harp seal fainted, he immediately cleaned the wound and rotten flesh in its mouth with medical cotton, and then cleaned it with spirits.

"I've cleaned up the wound, but there's nothing I can do about the teeth, unless I put a brace on it, or implant it directly." The accompanying doctor said.

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

As for dental implants, this is the first time Xiang Yang has heard of this professional term, let alone implement it.

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

The crew felt a little sorry.

In fact, Xiang Yang was also sighing inwardly.

It is the nature of seals to bite ice holes. As long as they live in the wild, how could this harp seal not bite ice holes?

Fang Youqun said with some pity: "Brother Yang, its teeth are all ground flat, so how can it eat?"

"Don't worry, as long as you give it the Antarctic krill, it will definitely be able to eat it." Xiang Yang said.

After the rotten meat in the harp seal's mouth was cleaned, the very unpleasant smell disappeared immediately.

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

Although the vast majority of Antarctic krill live in the surface layer of seawater within 50 meters, they are numerous.

But the mouth of the seal is very small, unlike the whale that can swallow a large amount of Antarctic krill in one bite.

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

In fact, Antarctic krill is also a very delicate marine creature. Although there are a large number of them, their 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 molt and shrink in size, which is not the case with other animals. Scientists speculate that this may be an adaptation of Antarctic krill to the limited food supply in winter.

The water temperature in the Southern Ocean is low all year round, and the salinity does not change much. There are no other factors such as rivers, rivers and people to interfere. Such a stable environment makes the krill become delicate, with poor adaptability, and cannot adapt to slight changes in the environment.
