Ao Muyang said, "If you apply some sunscreen, don't there be sunscreen on the island?"

Chen An shook his head and said, "It's useless. As soon as you dive, the sunscreen will be soaked in sea water. It's okay to lose some skin. This is not ultraviolet poisoning, I'm not afraid."

Ao Muyang said, "Then you have a good idea, don't let yourself suffer."

Chen An smiled and said, "I understand, boss, when will my uncle and others come to the island?"

Ao Muyang shrugged and said, "They can't come for the time being. The town has held an event to revive the traditional fishermen. They have to participate in this event for the time being and let them come after the event is over."

Chen An said: "Oh, I still expect my uncle to come and see what happened to coral bleaching."

When Ao Muyang heard this, he was surprised: "Your uncle still understands coral?"

Chen An said: "When my uncle was young, he went to work in the South China Sea with my father and raised corals. What I know about corals was what they told me."

Ao Muyang said: "Okay, I'll go and check the situation first and ask your uncle how to deal with this matter."

Chen An also knew some knowledge of corals. He said: "I just dived to see it. I think the environment is not good. Symbiosis algae cannot survive here. If the environment is right, it is estimated that Symbiosis algae will reproduce seriously, and then the corals will be able to recover their vitality."

Ao Muyang shook his head and said, "It must have nothing to do with the environment. This coral has lived in the sea for three or four years and has been fine. Now the undersea environment has not changed suddenly. How could the symbiotic algae suddenly die?"

His words made Chen An stunned: "Ah? It's only three or four years old. The coral area is quite large. They can't have expanded in the past three or four years, right?"

Ao Muyang nodded and said, "That's it."

Coral groups on the seabed are indeed expanding rapidly, and there are many reasons to control the reproduction and growth rate of corals. First, the number of new additions to most coral species is very low, and the number of offspring produced by sexual reproduction can survive and then join the group is very small.

Second, the mortality rate of small groups is very high, the growth rate is slow, and it is susceptible to invasion of other organisms, algae spatial competition and sediment coverage, which will lead to coral death.

Third, it takes a long time for small groups to grow to reproductive maturity, which usually takes more than 3 to 5 years.

Due to these factors limitations, only one of the tens of thousands of coral larvae may survive, so the natural reproduction of coral clusters is a long and complex process.

However, Ao Muyang used to keep eating gold drops for them. The coral polyps have extremely strong vitality, low mortality rate, fast growth rate, and amazing new additions. Therefore, the coral area can transform from dozens of square meters into dozens of acres in three or four years.

He couldn't tell Chen An about this, so he didn't say anything more and changed into the diving suit and jumped into the sea.

The seabed in the coral area is very beautiful, and the surrounding sea water changes from blue to bright green, which makes people feel comfortable.

As the scenes Ao Muyang saw became more and more beautiful and the colors became more and more gorgeous. Under the action of symbiotic algae, corals have many colors, and small fish of various colors traveled through them. No wonder corals are known as the "tropical rainforest in the ocean".

Although the corals are diverse in color, they are not white. Now there are white spots in some coral clusters, and the largest white spots are the size of someone's thumb belly.

This made Lao Ao feel very distressed. He began to release the gold droplets at any cost and dilute them.

Suddenly, the coral area became lively.

As the golden drops spread around, colorful fish first emerged from the coral bushes, and then the sea snake king came to hear the news. The fish were frightened and swam around, making the seabed even more lively.

The coral polyps also felt the temptation of the golden drops, and the coral clusters swayed. This was the golden drops that the coral polyps were preying on the sea water.

Seeing that Chen An had not entered the water, Ao Muyang used the skill of underwater magic. He moved around the entire coral area, constantly releasing the golden drops, and evenly dripping rain and dew.

After he had been walking around the coral area, he surfaced and returned to the island.

Chen An, who was squatting on the ground reading a book, looked up and said, "Boss, have you found a problem when you go down this time?"

Ao Muyang asked: "Don't keep it a secret, what's the problem?"

Chen An said: "There are only corals and fish in the coral area. This is not right. The coral area is an ecological area. It also needs jellyfish, sponges, giant clams, shrimps and crabs. Anyway, there are other starfishes."

If he didn't say it, Ao Muyang wouldn't pay attention to this.

There are many shrimp, crabs and fish in the fishing grounds, but none of them have coral symbiosis, so they don’t like corals specifically and accompany corals.

Chen An continued: "I have been reading coral books today. In the coral ecosystem, this symbiotic algae is amazing and has a high status. And not only the coral bodies have symbiotic algae, but many creatures in the coral reefs have symbiotic algae, such as sea anemones, jellyfish, sponges and tridacna. So I thought, maybe the life in this coral area is not rich enough, and there are not enough species of symbiotic algae. You know, if the number of species is small, it is easy to cause diseases to rage..."

As he said this, he suddenly stood up: "Hey, boss, do you think coral bleaching is caused by bacteria? The bacteria caused the death of symbiotic algae?"

Ao Muyang touched his nose and said, "Old Chen, you have proposed a good direction for exploration. Then I will take some samples and go back for testing. In addition, regarding the species problem in the coral area, I will solve it in the past two days."

He took samples from the bleached corals and brought them back to the village and handed them over to Li Ji and Su Penghui, asking them to help analyze whether there are bacteria inside.

This is simple, Li Ji found a student to do the culture medium and said that there would be results in twelve hours.

Taking advantage of this opportunity, Ao Muyang went back to make up for a sleep.

After waking up, he thought that the species in the coral area were not rich enough, so it had to be artificially added. After all, corals are alien species in the waters of Brick Island, and there are no species suitable for coral symbiosis in the surrounding waters.

The giant clams are good friends of coral groups. The former has a kind of zooxanthellae in its body, which can also coexist with corals.

It just so happened that when Ao Muyang helped Shen Zhifu explore the black chimney before, he found that there were many giant clams there, so he decided to find some giant clams in the black chimney waters to transfer to the coral area.

Do it as soon as you say it.

He had to throw a stone to ask for directions first and find out the salvage of the treasure.

Discovering Cai Qian's treasure is a major event. Now there are reports on the Internet that the treasure is coming back to light. However, these reports only introduce the background of Cai Qian's pirates and the antiques going to sea, but there is no introduction to the process.
