Golden Fishing Village

Ao Muyang then said: "Put on some sunscreen. Isn't there sunscreen on the island?"

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

Ao Muyang said: "Then just be aware of it and don't let yourself suffer."

Chen An'an smiled and said: "I understand, boss, when will my uncle and the 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 tradition of the fishermen. They have to participate in this event for the time being. We will let them come after the event is over."

Chen An'an said: "Oh, I also hope that my uncle will come to see about coral bleaching."

Upon hearing this, Ao Muyang was greatly surprised: "Your uncle still knows about coral?"

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

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

Chen An'an also knows some knowledge about corals. He said: "I just went diving to see it. I think the environment is not good and the symbiotic algae cannot survive here. If the environment is suitable, it is estimated that the symbiotic algae will reproduce properly. That way The coral will be able to regain its vitality.”

Ao Muyang shook his head and said: "It must not be directly related to the environment. This coral has been living in the sea for three or four years and has been fine. There is no sudden change in the seabed environment. How could the symbiotic algae suddenly die?"

His words made Chen An'an stunned: "Huh? It's only been three or four years? The coral area is not small. They didn't expand in the past three or four years, right?"

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

The coral colonies on the seabed are indeed expanding rapidly. There are many reasons that control the rate of coral reproduction and growth. First, the number of new additions to most coral species is very low, and the number of offspring produced by sexual reproduction can survive to join the population.

Second, the mortality rate of small groups is high, the growth rate is slow, and they are easily affected by factors such as invasion by other organisms, competition for algal space, and sediment coverage, which will all lead to the death of corals.

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

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

But Ao Muyang kept feeding them gold drops before. The coral polyps have extremely strong vitality, low mortality rate, fast growth rate, and an amazing amount of new additions. Therefore, the coral area can be transformed from dozens of square meters to one in three or four years. An area of ​​dozens of acres.

He couldn't tell Chen Ping'an this, so he changed into a diving suit and jumped into the sea without saying anything more.

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

As he dived from the surface of the water, the scenes Ao Muyang saw became more and more beautiful, and the colors became more and more brilliant. Under the influence of symbiotic algae, the corals had many colors, and there were also small fish of various colors shuttled among them. No wonder Corals are known as the 'tropical rainforest in the ocean'.

Although the colors of corals were originally diverse, there was no white color. Now white spots appear in some coral bushes. The largest white spot is the size of a person's thumb.

This made Lao Ao feel bad, and he began to release gold drops and dilute them regardless of the cost.

Suddenly, the coral area became lively.

As the gold droplets spread all around, first colorful small fishes jumped out from the corals, and then the Sea Serpent King came after hearing the news. The small fishes were frightened and swam around randomly, making the seabed even more lively.

The coral polyps also felt the temptation of the gold drops, and the coral bush swayed. This was the coral polyps preying on the gold drops in the seawater.

Ao Muyang saw that Chen Ping'an had not entered the water, so he used the skill of underwater magic. He moved around the entire coral area, constantly releasing gold droplets, so that the rain and dew would be absorbed.

After he walked around the coral area, he surfaced and returned to the island.

Chen An'an, who was squatting on the ground reading a book, raised his head and said, "Boss, did you find any problem when you went down this time?"

Ao Muyang asked: "Don't show off, what's the problem?"

Chen An'an said: "There are only corals and fish in the coral area, which is wrong. The coral area is an ecological area. It also has jellyfish, sponges, clams, shrimps and crabs. Anyway, there are no starfish."

If he hadn't said it, Ao Muyang really wouldn't have noticed this.

There are many shrimps, crabs and fish in the fishery, but they are not symbiotic with corals, that is, they do not love corals and live with them.

Chen An'an continued: "I have been reading books about corals today. In the coral ecosystem, this symbiotic algae is amazing and has a very high status. And not only are there symbiotic algae in the bodies of corals, but also in the bodies of many organisms in the coral reefs. There are symbiotic algae, such as sea anemones, jellyfish, sponges and clams, so I thought that maybe the life in this coral area is not rich enough, and the types of symbiotic algae are not enough. You know the boss, in an ecological area, Once the number of species is small, it is easy for diseases to spread..."

After saying this, he suddenly stood up: "Hey, boss, do you think coral bleaching is caused by bacteria? Bacteria cause the death of symbiotic algae?"

Ao Muyang touched his nose and said: "Old Chen, you have proposed a good exploration direction. 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 next two days."

He took a sample from the bleached coral and brought it back to the village to give it to Li Ji and Su Penghui, asking them to help analyze whether there were any bacteria in it.

This was simple. Li Ji found a student to make a culture medium and said that the results would be available in twelve hours.

Taking advantage of this opportunity, Ao Muyang went back to catch up on his 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 were alien species in the waters of Zhuantou Island, and there were no species suitable for coral symbiosis in the surrounding waters.

Giant clams are good friends of coral groups. The former have a kind of zooxanthellae in their bodies, which can also coexist with corals.

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

He did it right away.

He had to test the waters first and find out about the salvage of the treasure.

The discovery of Cai Qian's treasure was a big deal. Now the Internet is flooded with reports about the recovery of this treasure. However, these reports only introduce the background of Cai Qian's pirates and the information of the antiques that went out to sea, but there is no introduction to the progress.

The Coast Guard is responsible for the safety of the treasure salvage team, so Su Jinnan has the latest information about the treasure salvage, so he called Su Jinnan.
