My Deep-sea Fishery

A group of people hurried forward under the leadership of Xiang Yang.

"Stop." Only halfway through, Gao Chuang suddenly waved his hand and shouted loudly.

"Um?"

Everyone looked at Gao Chuang.

"What's the matter, Mr. Gao?" Xiang Yang also asked suspiciously.

"Look at the ice." Gao Chuang pointed in one direction and said.

Xiang Yang quickly looked in that direction.

I saw a very hidden depression in the white snow.

"Come on, let's go and have a look." Gao Chuang walked towards the depression in the snow.

When they got closer, Xiang Yang and others discovered that there was actually an oval-shaped ice cave under the depression in the snow. Under the ice cave, a seal was squinting its eyes and greedily breathing the air.

"There really is a freshwater lake." Gao Chuang said in surprise when he saw the seal.

Xiang Yang was a little stunned, "This seal's eyes seem to be broken."

"Oh? Really?" Gao Chuang quickly looked under the ice cave.

Sure enough, the seal's left eye was very bright, but its right eye was half-closed. The eyes were filled with a light yellow semi-liquid substance, which covered its entire right eye. As if blind.

When the seal saw so many people at the entrance of the cave, it panicked and dived into the water, and didn't show up again for a long time.

"That seal must have been under this ice cave for a long time." Xiang Yang analyzed.

Seals are amazing creatures that can live on land, under the sea, and even in fresh water.

However, after staying in fresh water for a long time, seals are prone to eye diseases. Although they are not blind, they are still very serious.

Seals are the most widely distributed species of pinnipeds. Seals have been found from the Antarctic to the Arctic, from seawater to freshwater lakes.

As early as a few years ago, some netizens reported that they saw two seals while visiting Baotu Spring in Jinan, and one of the seals may have eye problems.

This news caused many netizens to join the discussion at the time.

Some netizens said that this is nothing new. Many years ago, Baotu Spring raised seals.

It is said that seals are raised in Baotu Spring because Baotu Spring is dry. If Baotu Spring is dry, tourists will not come here to play.

So, the garden asked a master to give advice. The master said that if Baotu Spring is to keep spraying, it needs to get a few seals to raise.

Seals, seals, with seals, Baotu Spring has the same pronunciation as "Bao".

But then the staff of Baotu Spring refuted the rumors that Baotu Spring has been breeding seals for many years, and the rumors on the Internet that Baotu Spring introduced seals because of Feng Shui are false.

And there is evidence from locals that the two seals existed as early as their childhood.

However, netizens do not agree with this reply. Many people think that in order to retain tourists, Baotu Spring does not necessarily have to raise seals, but other fish or animals can be raised, because seals are adapted to sea water, and Baotu Spring is fresh water.

The eye diseases of Baotu Spring seals are caused by fresh water.

As a marine animal, seals are raised in fresh water, which can easily cause eye inflammation.

The rumors are not credible, but two things are certain, that is, Baotu Spring is indeed a seal, and Baotu Spring is indeed fresh water.

Therefore, seawater seals are absolutely able to live in freshwater.

And, as far as Xiang Yang knows, there is another kind of freshwater seal in this world.

There are many kinds of seals, most of which live in seawater, and the only freshwater seal is called the Baikal seal.

For Baikal seals, the scientific community generally believes that Lake Baikal seals should come from the Arctic Ocean, because they are the closest in blood relationship to the seals there.

The fat and round Baikal seals are quite dexterous in the water, and their swimming speed can reach 20 kilometers per hour.

After investigation, biologists found that the Baikal seals have flipper-like limbs, and the hind limbs are connected to the tail. They are always backward and cannot walk, so they are very clumsy on land.

Therefore, some scientists believe that the ancestors of the Baikal seals came to Lake Baikal from the Angara River.

But this statement has not been universally accepted.

The exact time when the seals came to Lake Baikal is still an unsolved mystery.

Scientists can only speculate that the arrival of seals to Lake Baikal most likely occurred during the ice age.

At that time, the Yenisei and Angara river basins were covered by ice and snow for a long time, and the riverbed became deeper. The range of seals living in the Arctic Ocean continued to expand to the south. They traveled thousands of kilometers to Lake Baikal.

When the ice age ended, the flow of the river decreased greatly and the river bed became shallower. These "guests from afar" had to stay here, and gradually evolved into the unique freshwater seals in the world.

The Baikal seal is the only seal in the world that can live freely in fresh water.

However, how they came to settle in this lake is a difficult thing to explain.

The Baikal seal is closely related to the Arctic Ocean seal.

But according to data, the southern part of the Siberian Plateau, where Lake Baikal is located, has never been submerged by sea water for more than 500 million years.

It is impossible for the ancestors of the Baikal seal to go from the remote Arctic Ocean to a completely different environment and continue to this day.

Gao Chuang lit a cigarette for himself, took a deep puff, and exhaled a puff of smoke mixed with hot air quite happily.

"We're waiting here. After the seal comes up, we put the sonar detector down in the ice cave to see if there are any fish caught in the ice lake."

Xiang Yang nodded in agreement.

The speed of the seal swimming under the water can be said to be as fast as the flash point. As long as the seal is in the water, basically there is no need to think about catching it. You can only climb up from the ice cave by yourself when it needs to take a breath.

Of course, Gao Chuang and the others could just ignore the seal and put the sonar detector down through the ice cave.

But that would undoubtedly lead to the death of the seal under the ice cave due to lack of oxygen.

The seals on the ice floes can slowly bite through the ice cave with their sharp teeth, but it is extremely difficult for the seals under the ice cave to bite through the ice cave.

After all, Gao Chuang's age is there, and his physical fitness is incomparable with that of young people. He is easily damaged by freezing in this icy world.

Xiang Yang couldn't help but said: "Mr. Gao, why don't we stay here, and you take two brothers back to call for someone, and let's try to see if we can receive a wave of goods under this ice cave."

A group of people subconsciously looked at Gao Chuang. In fact, what Xiang Yanggang said was exactly what they wanted to say.

It can be seen from Gao Chuang's slightly trembling hand holding the cigarette that Gao Chuang has actually reached the limit of what he can hold on to.

"I won't go back." Gao Chuang waved his hand, "First, we will detect whether there are any fishery resources worth fishing under this icy lake, and then we will make further plans."
