My Deep-sea Fishery

This is a sad thing.

Moreover, the human influence on blue whales is much more than that.

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

Although most of these are not enough to make blue whales deadly, they can cause blue whales to be injured.

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

At the beginning of the 20th century, there were quite a lot of blue whales in almost every sea area in the world.

In the mid-twentieth century, the wild hunting of whalers made the blue whales almost extinct.

It was not 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 about 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 was caught, which meant the birth of a rich man, or a richer family.

In recent years, due to the ban on whaling, the number of blue whales in the world has remained basically unchanged, probably at 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. It consists of approximately two thousand blue whale individuals. They are concentrated between Alaska and Costa Rica, but are common in California during the summer.

This blue whale population in the Pacific is the hope for a long-term recovery in 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 Pacific Northwest. It has been recorded between the Kamchatka Peninsula and the northern tip of Japan. Therefore, the protection of this blue whale population is very difficult, and it is still possible to be hunted down to this day. .

The southern ocean blue whale population is about 1,000.

Humans have yet to have a good understanding of how the blue whale population migrates in the Southern Ocean.

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

In addition, there are two blue whale populations living in the North Atlantic.

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

The second one is further east and appears in the Azores in spring and Iceland in summer. It is speculated that whales move between the two volcanic islands along the mid-Atlantic ridge.

"Captain, let's leave here as soon as possible." Fang Youqun suddenly said at this time.

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

Fang Youqun curled his lips, "I can't catch it. Just look at what's good, and this blue whale screams from time to time. The key is that I still can't hear it. When I think of this, my heart feels hairy."

Xiang Yang smiled, feeling Fang Youqun, the boy, was afraid because of the blue whale's call.

Thinking about it, Xiang Yang suddenly looked down. To be honest, if this blue whale really kept yelling, and people have been in such violent infrasound waves for a long time, it might not be a good thing.

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

As a result, the blue whale also chased here, and it seemed to be swimming at full force.

Xiang Yang felt strange, frowning and staring at the blue whale behind him.

To be fair, blue whales shouldn't 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 blue whales want to attack human ships, they shouldn't pick such a large ship to attack, right?

There is no reason.

Staring at the blue whale for dozens of seconds, Xiang Yang realized that there were still several water waves behind the blue whale.

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

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

It's no wonder that this blue whale will continuously spray water on the sea to change its breath, and then swim quickly. No wonder it will make the sound of whales. It turns out that it has encountered a natural enemy.

Xiang Yang took a close look at the blue whale and found that there was nothing injured on the blue whale. It seemed that the group of killer whales had not caught up with it.

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

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

But less than 25% of blue whales have traces of attack by killer whales.

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

Most of the time, killer whales can only kill blue whales by launching a surprise attack while they are eating.

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

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

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~www.readwn.com ~Finally, the blue whale is eaten by the killer whale.

Xiang Yang has seen this news. When Xiang Yang first saw this report, he still sighed that killer whales are powerful. As the largest animal on this planet, blue whales will be taken away by a group of killer whales with such a big gap. Kill head-on.

In Xiang Yang’s impression, it is not normal for killer whales to hunt blue whales.

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

But the body of the blue whale is there after all, and its terrifying power can severely wound the killer whale with only a light hit.

Thinking of this, Xiang Yang suddenly felt that killer whales are really very similar to lions on the grassland. Blue whales, like lions, are also typical social animals. Even the smallest killer whale group consists of at least five members. This is really too similar to the habits of lions.
