In fact, the whale's eyes are extremely incommensurate with its stature, a giant whale's eyes are only the size of a small watermelon, and generally can only see objects within 17 meters, and the eyesight is extremely degraded. A huge whale can't see as far as its own body.

But whales have their own way. It has no external ear shell and a thin external auditory canal, but it has a very sensitive sense of hearing, can sense ultrasound, and can rely on echolocation to find food, connect with companions, or escape predators.

This is how the fishery department of the Hantang Group understands the stranding of whales along the coast of the Ming mainland.

Generally speaking, whales swim into the bay in order to chase a school of fish, and when the whale swims close to the sea and emits ultrasound waves towards a beach with a large slope, the echo is often very incorrect, or even completely unreceivable, and the whale becomes disoriented.

This is the main reason why the Ming people are often able to pick up whales on the beach - in that world, there are also sources that say it is due to the influence of chemical pollution in the environment, sonar emitted by humans, and so on.

However, people in the fishery department of the Hantang Group believe that those may only be the reasons for aggravating the whale stranding, but not the fundamentals, otherwise why are most of the county records along the coast of the Ming Continent recording of whales being picked up? Where did chemical pollution and artificial ultrasound come from in the seventeenth century? The joke is the same.

But now it's really there.

The fishery department of the Hantang Group brought an ultrasonic generator for killing whales, which can imitate the ultrasonic waves emitted by many species of whales -- there is only one place in the world that sells them, and the small Japan of the world is not expensive and sells them publicly.

The fishery department of Hantang Group went to sea this time, and the object of the hunt was humpback whales.

The name "humpback" of the humpback whale is derived from the Japanese word "humpback", which means "pipa", referring to the shape of the whale's back. This type of whale is a tropical warm-sea cetaceans. The body is short and wide, generally 13 to 15 meters long, and weighs 25 to 30 tons.

It has a ratio of flesh to bone tissue to 1 to 1, a figure that people in the fishing department of the Hantang Group like.

Humpback whales are known for their out-of-water posture, long forewings and complex calls, and they are more active in pairs, docile and migratory in nature, but swim slowly.

Its staple diet consists of small crustaceans and small squatting fishes, which should be classified as baleen cetaceans.

Humpback whales inhabit the world's oceans, and there are many in the southern waters of Taiwan in that space.

For thousands of years, why did the Ming continent not give birth to a "whaling" culture?

This is a question, but the people of Hantang Group have already discussed it on the Internet, and in the end they reluctantly summed up a few:

The first is the idea of the unity of man and nature.

On the psychological level, the Ming people were mentally afraid of this kind of guy who they thought was the king of the sea, and there was a saying during the Tang Dynasty that "the big fish died, and the kings died" - but the emperor was the son of heaven and could naturally enjoy it with confidence, and a beautiful and magical object could only belong to the emperor. And the common people, even the elite, still have a sense of taboo about eating or using whale products, who called this whale too big?

This naturally affects the marketization of whale-related products in the people, just supply the royal, the market demand is not enough, not to mention, the royal does not give returns, only let the dedication, no one is willing to do.

Perhaps it was precisely because of this that the magnates on the Ming Continent retreated and chose the smaller shark to go under the knife.

They are very, very strange and like to eat shark fin, thinking that it is a great tonic, and that this kind of ordinary collagen, which is the same as pig hand jelly, has special effects, can nourish yin and aphrodisiac, and nourish essence...... This is not a question of whether you understand biology or not, even if science is popularized in the post-Qing era, there will still be a large number of people who think so. But the question is going to be sociology again.

The second is that the Ming people's technical means of killing whales are insufficient, and the Ming government's restrictions on the shipbuilding industry and the policy of banning the sea will have a negative impact.

Finally, the comprehensive utilization of whales is not enough, which is nothing, and the world is at the same level at this time.

Of course, this does not mean that people do not kill it at all, but mainly that there is no large-scale, long-term, and cultural - how many whales can be in this period? Is it a hundred times that of the world? Is there a 300 times?

In addition to its docile personality and its main production area, the humpback whale is also a regular north-south migration every year: migrating to the cold water sea for bait in the summer and breeding in the warm sea in the winter.

In this way, its activity location is relatively stable, and it is easy to block it. Its giving birth is around December, when it is more likely to be arrested with its cubs.

The mate of the humpback whale is monogamous, and the female gives birth every 2 years, and the gestation period is about 10 months, and each litter is born. It has a lifespan of about sixty years, and it can be said responsibly that they live much longer than the average life expectancy of people on the Ming Continent.

Another point is that the male humpback whale sings all day for about six months of the year, and the ratio of percussion to pure sound in his singing is very similar to the ratio of the two in Western symphonies.

According to the Hantang Group, humpback whales are also very good at singing in a "A-B-A" format commonly used by human singers, that is, singing a melody first, then further elaborating, and then returning to the original melody with a slight change.

In addition, they also engage in "artistic exchanges", and it is said that within three years of the Indian Ocean humpback whales migrating to Australia's Pacific waters, Australia's "indigenous" humpback whales abandoned their traditional repertoire in favor of singing new songs brought by these outsiders.

This habit of singing and communicating is exactly what the fishery department of Hantang Group will vigorously use.

According to the information of the Hantang Group, Yusan drove directly to 21 degrees 35 minutes north latitude and 117 degrees 28 minutes east longitude, which is close to the Dongsha group islands, rich in plankton, and theoretically is an active area for baleen whales and humpback whales, but the biological resources of this time and space are too rich...... Humpback whales may be disdainful of this place, so it cannot be inferred from the conventions of later generations.

When he arrived at the exact location, Captain Guo Ziren first turned on the whale detector, warmed up on the LCD screen for a while, and when the enterprising bar was full, the scanning began...... It's a pity that there is not such a good life, and it is basically an irregular red reflection group...... It's just a school of ordinary fish, and there is definitely no stock on the surface and under the water for two nautical miles around.

Captain Guo Ziren took out his walkie-talkie and contacted the observer on the mast, who tied himself to the observation post with a safety belt and looked around with a telescope...... Humpback whales like to jump out of the water and have a habit of spewing two to four meters of water vapor like other cetaceans...... But there's nothing here, and maybe the information on that side of the world isn't accurate.

Captain Guo Ziren smiled and said, "It's okay, they're not here, if we lure them here, they will definitely be fooled." ”

From the observer's walkie-talkie, Captain Guo Ziren could hear the whirring sea breeze and the observer's dissatisfaction...... There was still an hour before it was his turn, and no one liked to blow the sea breeze on it.

Captain Guo Ziren turned on the ultrasonic generator, selected the special humpback whale on the LCD screen, clicked it and left it alone, the design of Little Japan is very humane, it will choose the best combination of temptations by itself...... The joy of eating, the joy of finding a mate, the call for mates, or even the mating sounds, etc., do not make the humpback whale have a memory effect, nor do they cause confusion due to possible "dialects...... The combination is different every time.

Director Lin Shengli is with the ship this time, he has to be the first operator, and of course he has to guide other technicians...... He sat bored in the captain's room, looked at the radar screen, and said, "There is a Ming fishing boat in the distance...... But it doesn't seem to be ......."

Captain Guo Ziren glanced at it and said, "Five nautical miles to the northwest, no more than twenty tons...... It's not small...... There may be some small ones that can't be found, and this is not a traditional fishing ground. ”

"That was the day before yesterday, right?"

"I don't know, but they're going to come and ask us about the weather, the fishing, and so on -- it's too slow for them to look for it themselves."

"Haha, who came up with this trick, to broadcast the weather forecast and sea conditions on a loudspeaker--to make the Ming fishermen learn Mandarin-"

Director Lin Shengli shook his head with a smile and said, then picked up the telescope and looked into the distance...... I only saw two pieces of Daming-style hard sails, and there was a rag strip fluttering in the wind on the mast, which was probably measuring the direction of the wind, as if it was approaching here......

"They're coming towards us, and they look like they've been waiting there for a long time......"

His assistant took his binoculars casually, looked at them, and said, "Almost, didn't you tell them the news?" These Ming people are really unprofitable...... The boat is very fast, I don't know when it will get to us? ”

"More than two hours...... This is the era of sailing, and there are still people who are keen to do it......" Captain Guo Ziren said disdainfully, "I don't want to touch a sailboat in my life......"

The assistant exclaimed, "I'm cāo, looking so close, it's time to walk for so long, and it's too late to get a good night's sleep...... I also saw a small boat, and it was too bold...... Dare to go into the sea at such a young age! ”

Director Lin Shengli smiled and said, "I am more in favor of them mentioning that they will engage in sailing competitions in the future, not because of the pain in the egg...... It's a kind of spiritual training. ”

Captain Guo Ziren scratched his head and said he didn't understand, and Director Lin Shengli smiled and didn't say anything......

Suddenly, cheers came from inside the walkie-talkie.

"I'm here, here, at ten o'clock in the stern, I saw a whale jump out of the water...... It's about ten nautical miles away! ”

If there is one, there are two. Captain Guo Ziren immediately replied: "Continue to observe ......"

He hurriedly walked out of the captain's room, and said before he walked out: "Director Lin, you wait first, why will it take an hour before you can fire......

Captain Guo Ziren walked to the stern of the ship in an extra relaxed mood on the rickety deck, and held up the binoculars to observe...... Sure enough, there was a whale in the distance that jumped out of the sea from time to time, and as the sun flickered, you could still see its long flippers and white belly skin...... Otherwise, it's also called a longfin whale.

Captain Guo Ziren shouted happily: "Brothers, the Sea Boar Arch is here!" ”

Everyone started according to their job requirements...... Yu San slowly drove the car and turned around, but did not drive towards the humpback whales first...... I'm afraid to startle them, let's see how it goes.

Other technicians began to hoist the lifeboat...... There were four in total, and there were five fishermen in each boat, and a Ming security team member...... The security team had a Type 1649 rifle, not to guard the Ming fishermen, but to protect them in times of crisis.

Fortunately, before they saw the whales, these Ming fishermen seemed to be a little eager to try.

Captain Guo Ziren hugged his shoulders and watched them go down to the lifeboat one by one, sure enough, they had all gone to sea, no one looked scared, and the movements were skillful.

He thought to himself, these wise people know that we have a way to deal with whales...... Don't be afraid at all......

In fact, he didn't know that the Ming fishermen were not afraid, but it wasn't because of this, the fishermen had all heard of the power of the 1649-type firecracker...... Stones can be broken, what are you afraid of?!

PS: Since Monday, that is, since December 1st, I have been living entirely on subscriptions, that is, a subscription, giving me three cents - I currently only have a little more than 300 friends subscribed, and there are tens of thousands of friends who watch piracy outside.

The great gods are not afraid of piracy, they have iron fans; Hitting the street is not afraid of piracy, they just want someone to read the text. I'm most afraid of not being able to go up or down like this -- out of the more than 300 subscriptions, about 100 are subscriptions from pirate websites.

On Monday, I'm going to post in the wee hours of the morning, and that's when the book is really decided.
