Ao Jing learned sampling in the unit and collected it on the islands and reefs, and she "didn't learn" about underwater sampling, so she naturally didn't dare to get started easily.

This is not something that can be explained by self-study, even if the little old man taught her, she didn't dare to say that she had learned it without taking it twice.

However, she has a sweet mouth, a quick work, and a job in her eyes, so the teachers who follow her are willing to take her.

This time, the two main researchers of underwater sampling agreed to go into the water with them to observe the whole process.

After resting for the night, the next morning, after getting ready, the three of them went into the water in turn.

Ao Jing came to learn, and she followed the teacher and watched their movements carefully.

She has done underwater sampling many times, but the requirements are different in different eras. When she was studying, the equipment and instruments were already very advanced, and a lot of work could be done by underwater robots. But not now, most of the work still has to rely on manual labor.

Three hours in the morning, only a third of the task was completed.

They got on board for lunch and rested, continuing around three o'clock in the afternoon. If it goes well, I can finish today's work by 8 p.m.

By the afternoon, Ao Jing had been able to cooperate with the two teachers to complete part of the measurement and recording work, and her learning ability was so strong that almost all the teachers who took her praised her.

"In the past, a large area of pearl oysters was found in this area, but then more people collected it, and the surrounding environment was seriously damaged, and now the production of pearls is getting lower and lower, and in two years, maybe even the pearl oysters will not be visible."

One of the teachers sighed, his gaze a little melancholy.

He has been working here for almost six years, and the data show that the ecological environment of the seabed is deteriorating day by day, and the root cause of the depletion of fishery resources is indiscriminate fishing, as well as the extinction of shallow sea plants that have caused the destruction of the ecological chain, and the pollution caused by industrial development cannot be ignored.

"Alas, it is understandable that society needs to develop and progress, but it cannot be at the expense of the environment. It's a pity that we are soft-spoken, and there is no splash at all when the report is handed in. In a few years, I am afraid that I will not even be able to see corals. ”

The big guy is full of pessimism, and even the interest in chatting is almost gone.

In Ao Jing's memory, the island was actually well protected, and later a pearl oyster farm was opened around the island. If you can feed pearl oysters, it means that the surrounding water quality and biological chain should be well maintained.

The pearl oysters here are mainly "Hepu shells" and "white lipped oysters".

Pearl oysters prefer to inhabit shallow sea sand bottoms with clear waves, clear water, warm and smooth water, and abundant bait, and the salinity of the sea water should be appropriate.

Every year in April and May, pearl oyster larvae begin to multiply in large numbers. Artificially raising pearl oysters requires the implantation of a bead nucleus, which is usually implanted with plastic or stones. After a few months, the pearls begin to take shape, but it usually takes a year to several years for the pearls to be harvested.

Ao Jing heard that this was once an ancient pearl field, and immediately asked curiously if he was still harvesting pearls.

"Two years ago it wasn't. Nowadays, it is almost impossible to see mature pearl oysters, and the growth of the surrounding islands and reefs is not optimistic, so if you want to resume pearl oyster farming, you must build artificial islands and reefs. ”

Artificial reefs are easier said than done, and the amount of money invested is not small, and so far, no one has been told of any plans to rebuild a pearl oyster farm here.

"But if you want to play, you can go down and try it, and if you find a pearl oyster, you can catch it and open it."

They are not old pedants of sour rot, and as long as it is not a destructive salvage, generally no one will stop them from going into the water to find shells.

There are a lot of young people on the boat, and a few young people are combined, anyway, there is nothing to do, so they just go into the water to try their luck.

They also made a small bet that the person who found the pearl would be responsible for the dinner.

Ao Jing naturally did not break away from the collective, followed a few colleagues into the water, and then scattered to find the baby.

Her swimming and diving skills are not bad, she rescued the girl who fell into the water before, and she won the first place in diving in the fun sports competition organized by the unit.

This time she hoped that she could find some treasure and exchange money to buy a big house!

The protagonist in the novel always brings his own fortune, and he can find peerless treasures when he goes down to water. She didn't expect to find any rare treasures, just a few pearls in good condition, or other rare things.

Not to mention, she was lucky, next to a collapsed reef, she found a shell with a shell that looked like a rotten stone, and when she pulled it out, she was a good fellow, not much smaller than a soup pot.

This size must weigh at least ten pounds.

Dragging this big shell, Ao Jing floated to the surface of the sea.

"Qinqing, you found it so soon?"

The two older teachers, who were fishing on the boat, laughed and joked when they saw Ao Jing come out.

"This is a big guy, the teacher will help you take a hand."

The people on the boat fished up the shell with nets, and a group of people gathered around to see the surprise.

"With such a big shell, could there be pearls in it?"

Someone was about to open a shell, but was stopped by two teachers.

"They are still in the game, this is salvaged by Ao Jing, and if you want to open Bei, someone should open it."

The person who proposed Kaibei laughed wryly, and then sneakily changed his equipment and went into the water.

There are a lot of people on the ship, and not all of them are in one unit, and there are such people all the time, and they can't stop them.

It's just that there is such a person, so the two teachers simply gave up fishing and concentrated on taking care of the spoils for the young people who went into the water.

Ao Jing was lucky, he found more than a dozen pearl oysters before and after, and I don't know if there are pearls in them.

She also found a small, rusty iron box that she had discovered while digging shells out of the sand.

The little tin box was quite heavy, and the lock was good, but it was covered in green patina, and there were signs of corrosion from the sea, and some oysters and barnacles attached to it.

Such salvaged seabed sediments can be preserved by private individuals as long as they are not cultural relics.

Ao Jing didn't go into the water again after picking up this box, got on the boat and changed his clothes, planning to open the copper box first to take a look.

As she was about to unpack, the young men she had basically bet on were on board.

There is not much difference between everyone's harvests, the worst one finds two or three, and the most is Ao Jing, which is full of twelve.

At the normal level, six or seven are more often found.

Seeing Ao Jing salvage a copper box, the big guys all gathered around curiously.

It is not difficult to open the box, and this copper box is not a valuable cultural relic, and if it is damaged, it will be damaged.

After violently removing the lock, the contents are revealed.

It is a set of porcelain, and the style should be a folk kiln work of the Ming Dynasty. However, after so many years of immersion in seawater, the surface of the porcelain has been slightly damaged.

Ao Jing flipped cautiously, and finally shrugged.

"I thought there would be something valuable, but that's it, I guess the museum won't accept it."

This is true, after all, there are a lot of cultural relics salvaged from the sea every year, and the research value of this kind of porcelain from the folk kiln is not high. If you meet someone you like, you may pay for it to collect it and donate it to the museum, so you can only pile it up in the warehouse.

"Eh, if you don't plan to donate to the museum, I'll introduce you to a person, the other party has always wanted to receive a complete set of Hailao porcelain. I think your set is in good condition, maybe the boss is willing to give money to collect. ”

Hey, someone will send a pillow when you doze off, her old house, okay!
