My Deep-sea Fishery

Speaking of it, dugongs are also an extremely poor marine creature. They need to spend a lot of time eating every day, because it takes in a lot of food, but its movement speed is very slow, and it lacks effective It attacks the means of defense, so its natural enemies are very numerous.

Basically, as long as there are marine predators larger than dugongs in the ocean, they are the natural enemies of dugongs.

Because the body fat content of dugongs is very high, so for humans, dugongs are also treasures all over their bodies.

The most valuable thing on a dugong is its oil. The long-burning lamp made of dugong fat is loved by countless dignitaries at home and abroad. It is said that the legendary shark oil lamp is made of dugong oil.

In addition, dugong skin is also the best material for making leather. In Paris, which is full of romanticism, there was a time when a trouser belt made of dugong leather was sold at a sky-high price of 70,000 francs.

In addition, the dugong has a large skeleton, and its bones can be made into valuable sculpture decorations.

So there was a time when fishermen all over the world were hunting dugongs crazily. The docile dugongs became victims of human commercial interests. edge.

The group of dugongs that Xiang Yang saw in front of him consisted of five dugongs, two big ones, one half-big one, and two small ones. It looked like a family of five.

In fact, this family of five is considered a very large group among the dugong group.

Dugongs like to live together as a family unit. A normal dugong group usually has two to three heads, usually two big ones and one small one. Young dugongs will leave their parents to live alone after adulthood, while adult dugongs generally have When the offspring are minors, they will not continue to reproduce.

The gestation period of a dugong is generally 11 to 14 months, and it takes 7-8 years for a newborn dugong to become an adult. Xiang Yang guessed that the half-old dugong in front of him should be about five years old. The young dugongs are under two years old, because it usually takes about three years for an adult dugong to conceive a second time after giving birth to a young dugong.

It is really not easy for dugongs with such low reproductive ability to form a family of five, because young dugongs often become food for other large carnivorous marine organisms, and normally only one of ten young dugongs can grow up to adulthood.

The slow reproduction rate of dugongs and the harsh living environment have reduced the number of dugongs in recent years. Up to now, few fishermen can hear "mermaids" singing on the seaside reefs in summer.

Xiang Yang didn't want to scare this group of docile dugongs, and slowly retreated towards the muddy ground behind.

Seeing Xiang Yang retreating, a little dugong seemed to be curious about Xiang Yang, trying to swim towards Xiang Yang by pulling its clumsy limbs.

The action of the little dugong immediately frightened the big dugong, the female dugong hurriedly pulled the little dugong back, while the male dugong kept watching Xiang Yang covetously.

Xiang Yang smiled, and he really understood the saying that a newborn calf is not afraid of tigers. According to the temperament of an adult dugong, he saw that he was in ruins and ran away at this time. It must be because of protecting the two little dugongs, but the little dugong is still aggressive towards him. Swimming here, thanks to Xiang Yang is not a ferocious marine predator, otherwise the little dugong must have delivered food.

Returning to the silt-covered sea area, Xiang Yang didn't look for the clam shells any more, and went directly to the sea. He had been separated from the crew for a while, and if he didn't return to the sea, it might cause unnecessary trouble. flustered.

"Captain, you have finally come up. I was looking for you under the water just now. Where have you been?" Chen Qingsheng shouted when he saw Xiang Yang showing his head.

Xiang Yang climbed onto the deck and took off the helmet on his head, "I saw a few dugongs under the sea just now, so I chased them to have a look."

"Dugong is a big guy, Xiaoyang, are you not injured?" He Mingde asked with concern.

"It's okay, creatures like dugongs look big, but they are actually very timid. They ran away immediately when they saw me, and I didn't get close to them." Xiang Yang said with a smile.

"That's right, creatures like dugongs will run away as soon as they get the slightest fright. I've never heard of dugongs attacking humans." He Mingde nodded.

Fang Youqun came over and said regretfully, "Brother Yang, uncle, what is this dugong you are talking about? Why have I never heard of it?"

"I've never heard of a dugong, but you must have heard of its other name." Chen Qingsheng said slyly.

"That's not necessarily the case. I've read far fewer books than you can imagine."

Fang Youqun actually went to a junior high school, but he didn't even know how he got through that junior high school. Excluding biology and geography, the final exam of the last semester of the third year of junior high school added up to seven subjects that he had failed to pass. 100 points.

"It's a mermaid." Xiang Yang smiled and said, "Is it impossible for you not to have heard of this?"

Fang Youqun opened his mouth into an O shape, "A mermaid?"

"That's right." Chen Qingsheng said with a half-smile.

Xiang Yang smiled and nodded.

He Mingde also looked at him with a smile.

"The kind of mermaid with a human upper body and a fish lower body?" Fang Youqun asked.

"What do you think?" Chen Qingsheng asked back.

Fang Youqun ignored Chen Qingsheng, chased Xiang Yang and asked, "Brother Yang, is the mermaid you saw a male or a female?"

At this time, Song Chaoshu came over, "The mermaid your boss saw is not the same creature as the mermaid you thought of. The dugong is a close relative of the manatee. It is a vegetarian mammal. It looks like a manatee except for its tail. Almost identical."

"So it's a manatee." Fang Youqun clearly showed a hint of disappointment on his face.

"Boss Song." Xiang Yang hurriedly greeted him, "Have you heard of dugongs as well?"

"It's not just that I've heard of it, I've seen it." Song Chaoshu said with a smile: "I don't know if the group I saw with Boss Xiang is the same group, if it's the group I saw, then they often appear at night There are five in total near the coast in this sea area, so they come here to look for food during the day."

Xiang Yang raised his eyebrows, "I see five heads, two big ones and three small ones, Boss Song often sees them?"

"Yes, I prefer the location by the sea. The sea view villas in the city are generally open, and many people go for a walk every day, making it too noisy, so I bought a piece of land in the countryside and built it myself. I didn't expect to find out that I'm a neighbor with 'Mermaid'." Song Chaoshu nodded.
