My Deep-sea Fishery

It's a sad thing.

Moreover, the impact of humans on blue whales goes far beyond that.

In addition to direct damage to blue whales by humans through whaling ships, there are also a large number of blue whales colliding with ships or becoming entangled in fishing equipment.

Although most of these are not enough to kill the blue whale, they can hurt the blue whale.

Coupled with more and more human activities in the ocean, more and more noise in the sea makes it difficult for blue whales to communicate with each other, which may also lead to the death of blue whales.

At the beginning of the 20th century, blue whales were abundant in almost every ocean in the world.

In the middle of the twentieth century, the crazy hunting of whalers made the blue whale almost extinct.

It wasn't until humans began to consciously protect blue whales in 1966 that the number of blue whales gradually increased.

In 2002, a research report estimated that the number of blue whales in the world was around 5,000.

Xiang Yang knew that this was impossible.

The blue whale is one of the most important economic species in the entire sea. It has a lot of fat. In the last century, every blue whale captured meant that a rich man was born, or a rich man had a richer family.

Due to the prohibition of whaling in recent years, the number of blue whales in the world has remained basically unchanged, at about 5,000.

Since the creation of the Red List of Threatened Species, blue whales have been listed as endangered species on the Red List.

Currently, the blue whale population in the northeastern Pacific Ocean is the largest of all blue whale populations, consisting of about two thousand individuals, and they are concentrated between Alaska and Costa Rica, but are common in California during the summer.

This population of blue whales in the Pacific Ocean is the hope for the long-term recovery of the number of blue whales in the future. It is protected by many countries in the world and all hunting is prohibited.

However, sometimes this blue whale population will drift to the northwest of the Pacific Ocean. It has been recorded that it appeared between the Kamchatka Peninsula and the northern tip of Japan. Therefore, the protection of this blue whale population is very difficult, and it may still be hunted to this day. .

The population of blue whales in the Southern Ocean is around 1,000 individuals.

The migration patterns of this population of blue whales in the Southern Ocean are not yet well understood.

In Chile, locals often find blue whales gathering along the coast of Chilu Island for food. Therefore, the Chilean Cetacean Conservation Center, with the support of the Chilean Navy, conducts extensive research and protection on it.

In addition to this, two populations of blue whales live in the North Atlantic.

The first was in the Gulf of St. Lawrence. It is estimated that there are about 500 heads.

The second is more easterly, with the Azores in spring and Iceland in summer, where the whales are presumed to travel along the mid-Atlantic ridge between the two volcanic islands.

"Captain, why don't we leave here quickly." Fang Youqun suddenly said at this moment.

Xiang Yang raised his eyebrows, "Why, don't want to see more blue whales? There are not many blue whales in the world now. If you miss this one, you don't know when you want to see blue whales again next time."

Fang Youqun curled his lips, "I can't catch it, just to see what's interesting, and this blue whale roars from time to time, the key point is that I still can't hear it. When I think of it, I feel hairy."

Xiang Yang smiled, feeling that Fang Youqun is afraid of the blue whale's cry.

Thinking about it, Xiang Yang suddenly turned serious. To be honest, if this blue whale is really screaming and people have been in this kind of intense infrasound waves for a long time, it may not be a good thing.

Thinking of this, Xiang Yang immediately ordered the boat to start sailing in the opposite direction of the blue whale.

As a result, the blue whale also chased this way, and seemed to be swimming with all its strength.

Xiang Yang felt strange, frowned and stared at the blue whale behind him.

Reasonably speaking, blue whales should not attack human ships.

Moreover, the fleet that Xiang Yang is currently in is not a simple fleet. Every fishing boat in it is bigger than the blue whale.

Even if the blue whale wants to attack human ships, it shouldn't choose such a large ship to attack, right?

There's no reason for that.

After staring at the blue whale for dozens of seconds, Xiang Yang discovered that there were actually a few waves of water behind the blue whale.

Xiang Yang took a closer look, and immediately took a deep breath. It turned out that a group of tiger sharks were chasing the blue whale under the water.

This group of killer whales has seven or eight heads. It is not a big group in the killer whale group, but in the ocean, it is definitely a group of unscrupulous creatures.

No wonder this blue whale sprays water continuously on the sea surface to breathe, and then swims quickly. No wonder it makes a whale cry, it turns out that it has encountered a natural enemy.

Xiang Yang took a closer look at the blue whale, and found that there was no injury on the blue whale. It seemed that the group of orcas hadn't caught up with it.

In fact, Xiang Yang knew that as long as the killer whale was noticed by the blue whale, it was basically impossible to kill the blue whale.

According to statistics, more than half of the blue whales in the world have been attacked by killer whales.

But less than 25% of blue whales have signs of being attacked by killer whales.

This means that most of the time, even if killer whales attack blue whales, they can't even leave injuries on blue whales.

Most of the time, killer whales can only kill blue whales if they attack while they are eating.

But things are not absolute. If there are enough killer whales, there is a chance to kill the blue whale.

Just in March of this year, something happened in the sea that many ocean lovers all over the world are talking about.

On March 18 this year, the British "Daily Mail" reported that on the west coast of Australia, an adult blue whale strayed into the breeding grounds of killer whales and was killed by 75 killer whales. Whales share their food.

Xiang Yang has seen this news before. When Xiang Yang first saw this report, he was still lamenting the powerful fighting power of killer whales. As the largest animal on the planet, blue whales would be killed by a group of killer whales with such a large difference in size. Frontal kill.

In Xiang Yang's impression, it is not normal for killer whales to kill blue whales. When killer whales and blue whales meet, it is normal for both sides to lose.

Although killer whales are the largest dolphins in existence and the most ferocious toothed whales, their ecological niche in the ocean is similar to lions on the African savannah. Not only are they huge in size, adult killer whales have an average body length of about 6 meters and a weight of The average is about 5 tons, and the killer whale's big mouth has very sharp conical teeth, which are standard for top predators in the ocean.

But the body of the blue whale is there after all, and its terrifying power can seriously injure the killer whale with just a light bump.

Thinking of this, Xiang Yang suddenly felt that killer whales were very similar to lions on the grassland. Blue whales, like lions, were also a typical group animal. Even the smallest group of killer whales had at least five members. This is really too similar to the habits of lions.
