After hearing Lu Zhizi's words, Ao Muyang was stunned: "What do you need? Whale urine?"

Lu Zhizi ignored his questions and replied on his own: "I checked some information. Since the corals are almost fixed, they are not good at searching for food. They can only filter the water around them and wait for the nutrients they need to come to them."

Ao Muyang nodded and said, "I know this, but what does this have to do with whale urine?"

Lu Zhizi stretched her face and said, "When the teacher teaches, students are not allowed to interrupt randomly."

Ao Muyang waved his hand and said, "I'm sorry, Teacher Lu, you continue."

Lu Zhizi suddenly laughed: "Haha, tease you, everyone is equal when studying. When you encounter problems, you have to ask questions. OK, now I will solve your problem."

After thinking for a while, she organized the language and said, "Continue with the topic I just said that if coral polyps want to draw nutrients from the surrounding sea water, they must first have ingredients to absorb. Among them, fish account for a large proportion of the nutrient sources required by coral reefs. They are mobile nutrition for coral polyps."

Hearing this, Ao Muyang vaguely understood what she meant: "Oh, are you saying that I should let the fish get close to these coral polyps?"

In order to allow coral polyps to share as much as possible, he drove all the fish out. Later, he found that coral polyps were not active, so he did not dare to let the fish out of the coral polyps, for fear of affecting their vitality.

According to Lu Zhizi's meaning, Ao Muyang's actions were counterproductive.

Lu Zhizi nodded and said, "Australian oceanography expert Dr. Orgheyer led a team to study the symbiosis of coral reefs and fish schools in many places. In the past, everyone believed that corals were ocean oasis, providing a place for fish schools to survive, and unilaterally contributed to fish schools. In fact, this is not the case."

"The relationship between the two parties is symbiotic and mutually beneficial. For example, the coral reefs in the Caribbean Sea. Large fish will use the coral reefs as shelter during the day and as hunting grounds at night. They will naturally secrete ammonium through the gills of fish, which is a necessary nutrient for the growth of coral reefs. In addition, the phosphorus contained in the urine of fish is another key nutrient."

"Among them, fish urine is the most important thing for coral reefs!" She emphasized her tone in this sentence.

Ao Muyang laughed and said, "Is this research reliable? If so, I will get some urea for the polyps."

Lu Zhizi glared at him: "Don't smile. Dr. Orgheyer investigated 150 species of fish in 43 different coral reefs in the Caribbean Sea, and then found that coral reefs with more predatory fish nearby have richer diets and better activity. Coral reefs with fewer fish lack some essential nutrients. The fewer fish, the worse activity."

Ao Muyang said: "I understand what you mean. In short, this last sentence is the point. If a coral polyps want to be full of vitality, they have to survive with the fish."

Lu Zhizi snapped her fingers and said, "It's totally correct."

Ao Muyang said: "But I still have to ask, this is a bit like a fallacy. Where did you see it? I believe that fish and polyps coexist, but is it because of fish urine?"

He looked puzzled.

Lu Zhizi threw a magazine to him and said, "If you can understand it, just read it yourself. The complete study was published on page 28 of this issue. I asked my classmates from the United States to mail it back."

Ao Muyang took the magazine and saw a few letters on the cover: "nature".

Although his English proficiency is only in high school, he knows this word, nature means nature, so this magazine is the famous "Nature" magazine.

If Lu Zhizi gets the information from Nature magazine, there is no need to have questions. This magazine is the earliest international scientific and technological journal in the world. Since its inception in 1869, it has consistently reported and commented on the most important breakthrough in the global scientific and technological domain.

Since the problem has been found, Ao Muyang has to solve it.

In order to protect the polyps, he also used a net to cut the polyps' living area independently, and separated them from the fish school thoroughly.

As a result, his actions were counterproductive.

Finally he asked again: "In addition, you just said that this is related to whale urine, but the research you later said has nothing to do with fish urine."

Lu Zhizi said: "This involves another feasibility study report. Do you want to listen to the detailed version?"

Ao Muyang made a quick decision: "No, I want to listen to the summary version."

Lu Zhizi smiled slightly and said, "The summary version is that whale urine has the highest nutritional content in fish urine, and in addition, they also have the largest urine volume."

Ao Muyang touched his chin and said, "I think it is not necessary to use whale urine to water coral polyps. Their urine may be rich in nutrients, but as the saying goes, too much is too little. In traditional Chinese medicine, eating too much nourishing supplements is even more terrible than taking poison."

Lu Zhizi curled her lips to speak, and Ao Muyang rushed to say, "Really, there was a grape planted in front of Fugui's house. We wanted to eat grapes early, so my friends made an appointment to urinate the grapes together, but in the end, they were fermented to death within two days!"

"This grape is so pitiful. It actually met you," Lu Zhizi laughed and said, "But the coral polyps in your fishing ground are probably crazy about lacking nutrition!"

Ao Muyang finally recognized Lu Zhizi's words. He returned to the fishing ground and first removed the isolation net, and then threw a little gold.

Immediately, the big yellow croaker, the croaker, the milkfish and the tuna came together, with great momentum.

There is another most fierce one, that is, tigers.

A killer whale is a type of large baleen whale. The amount of urine of a tiger is very strong and can spray three meters against the current. If it turns over and pee at the sea, it will be like a small fountain!

Turning over and sitting on the tiger's head, Ao Muyang patted its head and wanted it to urinate.

As a result, he racked his brains and thought for a while, but no matter what, he could figure out how to make the tiger understand the idea of ​​asking it to pee...

The advice given by Lu Zhizi is very effective. As fish begin to approach coral groups, the activity of corals begins to improve.

They are still not as energetic as they are in the incubator, but they can already sway their tentacles to hunt, and their whole body has become more colorful.

Ao Muyang breathed a sigh of relief. The waters around Brick Island are definitely not the ideal sea areas for polyps to survive. As long as these small insects can survive, he did not expect that the polyps can explode here.

In order to make the polyps live better and create coral reefs faster, he then purchased zooxanthellae through Land Rover.

Zyxozoa can be said to be a kind of seaweed or a golden intercellular symbiotic bacteria.

They are very small, and there are at least 30,000 zooxanthellae in a cubic millimeter of coral tissue. They coexist with coral polyps and can provide coral polyps with photosynthesis products such as glucose, glycerol, amino acids, etc. 90% of the energy required by coral polyps is provided by coral polyps.

Also, he also purchased coral algae. In fact, coral polyps cannot build coral reefs independently. During the reef construction process, the main helper is coral algae.
