My Deep-sea Fishery

Although the fin whale is known as the swimming champion, Xiang Yang is confident that he can swim faster than that fin whale. If this fin whale intends to hurt someone, Xiang Yang will definitely escape immediately.

When Xiang Yang got closer, he found that the fin whale that had swum to the South China Sea was very likely to be a North Sea whale.

Fin whales have a very strange phenomenon. Like humans, they also have regional differences. Fin whales in the North Sea have very obvious regional differences. Although their appearance and body parts are similar, fin whales in the North Sea are generally more Fin whales in the southern hemisphere and near the equator are generally fatter, which is related to their diet structure.

Xiang Yang speculated that this fin whale might have lost itself with the group because of its fun or some danger, so it swam all the way from the North Sea to the South China Sea.

Xiang Yang's guess is well-founded. Compared with other cetaceans, fin whales are a group of very gregarious whales. They usually form a group of 6-10 individuals.

When hunting, the number of fin whales is even greater, and sometimes dozens of groups gather together to move together, and the number reaches an astonishing few hundred. The white-headed fin whales float on the sea, and the scene is not to mention how spectacular it is up.

This fin whale has a slender body, and it is alone, not with other fin whales. It is very likely that it is a North Sea fin whale.

In addition, fin whales are famous swimming champions. They are one of the fastest swimming whales. The highest record even reaches 40 kilometers per hour. It is entirely possible to swim from the North Sea to the South China Sea.

The fin whale was slowly eating.

After Xiang Yang swam close, it seemed to have found Xiang Yang, and immediately stopped eating, flicked its tail, and then accelerated to swim elsewhere.

Xiang Yang was stunned, the fin whale didn't like him so much.

But this is not surprising.

The character of fin whales is at two completely different extremes from that of humpback whales. If humpback whales are green forest heroes in the ocean, then fin whales are iceberg beauties in the ocean. They are extremely "proud" in character, basically It will not have too much contact with any creatures other than its own kind and food, and never actively approach humans and passing ships.

For this reason, it is very difficult for biologists to observe fin whales at close range. Human beings have not yet understood the time when fin whales come out of the water. Even if someone occasionally sees them come out of the water, it is usually in the distance.

However, some scientists have made a set of conclusions about the diving of fin whales.

Scientists divide the diving of fin whales into deep diving and shallow diving. During shallow diving, fin whales will surface for air every 2 to 3 minutes, and each breath will take about 5 seconds. When breathing out of the water, the head, shoulders, back and the raised caudal fin will all come out of the water, and sometimes the head will be lifted very high out of the water in order to take a breath.

No one can know the data of deep diving in such detail. Biologists can only confirm that fin whales can dive to a depth of about 200 meters. The longest observation time record is more than 20 minutes. As for Whether this will be the limit of fin whales, no one knows.

This fin whale is now diving shallowly. After avoiding Xiang Yang, it floated towards the surface of the water. When it was about to reach the surface of the water, it suddenly accelerated, and then Xiang Yang saw it leap up, and then flew in the air. Twisting, and then leaning sideways into the water, a huge wave like a bomb exploded on the water.

After falling to the surface, the fin whale continued to beat the waves with its body, and then let out an extremely melodious and low-pitched whale call from its throat.

The call was very long, and there seemed to be many different sounds, each sound lasted about one to two seconds, as if it was a human singing.

The fin whale repeatedly let out a melodious call that sounded sad and deep.

Xiang Yang raised his eyebrows, now he can be 100% sure that this fin whale is really a North Sea fin whale.

The sound frequency of fin whales is very low and can be transmitted hundreds of kilometers away. It is singing like this now, it should be calling its own group.

"Unfortunately, this fin whale is doomed to be in vain." Xiang Yang shook his head, the distance between the South China Sea and the North Sea cannot be crossed by the sound of a whale.

What Xiang Yang didn't know was that he was lamenting for the fin whale on one side, while on the other side the ocean-going fishing boat was blown up.

The fin whale was more than ten kilometers away from the fishing boat. The crew on the boat did not see it when it jumped out of the sea, but when he called, all the crew on the boat heard it immediately.

Xu Fang was sitting beautifully on the edge of the deck, dangling his legs, smoking a cigarette beautifully with his hands lying on the side of the ship.

Suddenly, he heard a low mechanical sound, and he was so frightened that the cigarette in his hand dropped. He thought it was a problem with some mechanical equipment of the ocean-going fishing boat.

That would be terrible, this was his first day as chief engineer, if the fishing boat broke down, let alone what Xiang Yang would do to him, he would not be able to forgive himself.

Not only Xu Fang was nervous, but everyone in the engineering team competed, checking everywhere in a hurry.

In fact, this can not blame them.

It is really that the sound frequency of the fin whale is too low, too much like the hum of a machine.

When humans first recorded fin whale calls, they thought they were mechanical failures.

Until the former Soviet Union period, some people thought it was a phenomenon of geophysics, and even the U.S. Navy once made a joke about it, thinking that it was a submarine from the former Soviet Union, and it cost a lot of manpower and material resources to detect it frantically.

Until today, biologists have determined that the unusually loud, long-lasting and purely regular sound is made by fin whales. If most fishing boats hear this kind of sound at sea, they will immediately call it The boat stopped for a full inspection of some of the hull's so machinery.

After Xu Fang inspected all the machines carefully, and put his ear on some machines and listened for a while, the people on board breathed a sigh of relief, "It's not that the machines on the ship are malfunctioning."

As soon as Xu Fang's words came out, the minds of the crew became active.

Especially those crew members who came from Ocean University, some of them even guessed that there should be a fin whale nearby, and all of them were gearing up and their eyes were shining.

At this time, the crew members who were fishing turbot under the water also returned to the boat.

Xiang Yang also quietly left the fin whale at the right time, swam back to the sea area where he set off first, and swam towards the sea.
