Golden Fishing Village

After hearing what Lu Zhizi said, Ao Muyang was stunned: "What do you need? Whale urine?"

Lu Zhizi ignored his question and answered to himself: "I checked some information. Since corals are almost immobile, they are not good at searching for food. They can only filter the surrounding water and wait for their needs. Nutrients come to them.”

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

Lu Zhizi said with a straight face: "When the teacher is teaching, students are not allowed to interrupt randomly."

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

Lu Zhizi suddenly laughed: "Haha, I'm kidding you. When studying, everyone is equal. When you encounter problems, you have to ask questions. Okay, now I will solve your problems."

After thinking for a while, she organized her words and said: "Continuing with the topic I just said, in order for coral polyps to absorb nutrients from the surrounding seawater, they must first have ingredients to absorb. Among them, fish account for a large proportion of the nutritional sources required by coral reefs. They are mobile nutrients for coral polyps.”

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

In order to allow the coral polyps to eat as much as possible of the small gold drops, he drove away the fish. Later, he found that the coral polyps were not very active, and he did not dare to let the fish get close to the coral polyps for fear of affecting their vitality.

According to Lu Zhizi's intention, Ao Muyang's behavior was counterproductive.

Lu Zhizi nodded and said: "Australian oceanography expert Dr. Allgeier led a team to study the symbiosis between coral reefs and fish schools in many places. In the past, everyone believed that corals were ocean oases, providing a living place for fish schools. , unilaterally dedicated to the fish, but this is not the case.”

"The relationship between the two parties is symbiotic and mutually beneficial. Take the coral reefs in the Caribbean, for example. Large fish will use the coral reefs as a refuge during the day and as a hunting ground at night. They will naturally secrete ammonium through their gills, which It is an essential nutrient for coral reef growth, and phosphorus contained in fish urine is another key nutrient.”

"Among them, fish urine is the most important to coral reefs!" She emphasized this sentence.

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

Lu Zhizi glared at him: "Don't be so playful, Dr. Allgeier investigated 150 species of fish in 43 different coral reefs in the Caribbean, and found that coral reefs with more predatory fish nearby have a richer diet and better activity. Coral reefs with fewer fish lack some necessary nutrients. The fewer fish, the less active they are. "

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

Lu Zhizi snapped his fingers and said, "That's absolutely correct."

Ao Muyang said: "But I still have to ask, this is a bit like a heresy. Where did you see it? You said that fish and corals live in symbiosis. I believe it, but is it because of fish urine?"

He looked puzzled.

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

Ao Muyang took the magazine and looked at it. On the cover were the letters: "Nature".

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

If the information Lu Zhizi obtained came from the magazine "Nature", then he would not have any doubts. This magazine is the world's earliest international science and technology journal. Since its inception in 1869, it has consistently reported and commented on the global science and technology network. the most important breakthrough.

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

In order to protect the coral polyps, he also used nets to separate the living areas of the coral polyps, completely separating them from the fish.

As a result, what he did was counterproductive.

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

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

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

Lu Zhizi smiled slightly and said: "The summary version is that whale urine has the highest nutritional content among fish urine. In addition, their urine volume is also the largest."

Ao Muyang touched his chin and said: "I don't think it's appropriate to use whale urine to water coral polyps. Their urine may be rich in nutrients, but as the saying goes, too much is not enough. In Chinese medicine, if you eat too much nourishment and overdo it, it will be worse than overdoing it. It’s scary to take poison.”

Lu Zhizi curled his lips and wanted to speak, but Ao Muyang rushed to say: "Really, there used to be a grape planted in front of Fugui's house. We wanted to eat the grapes early, so the friends made an appointment to urinate and fertilize the grapes. As a result, no two It’s so fucking crazy!”

"It's so pitiful that this grape plant has come across you," Lu Zhizi said with a smile, "but those coral polyps in your fishery are probably going crazy due to lack of nutrients!"

Ao Muyang finally agreed with Lu Zhizi's words. He returned to the fishing ground and first removed the isolation net, then dumped some gold drops.

Immediately, large yellow croaker, turbot, sole, and tuna came together with great momentum.

There is another most ferocious one, the tiger.

Killer whales are a large toothed whale. The tiger's urine volume is very strong. It can spray three meters against the current. If it turns over and urinates on the sea surface, it will be like a small fountain!

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

As a result, he racked his brains for a while, but he couldn't figure out how to make the tiger understand that he wanted it to urinate...

The suggestion given by Lu Zhizi was very effective. Since the fish began to approach the coral group, the activity of the corals began to improve.

They are still not as energetic as in the incubator, but they can swing their tentacles to hunt, and the color of the whole body has become gorgeous.

Ao Muyang breathed a sigh of relief. The waters around Zhuantou Island are definitely not ideal for coral polyps to survive. These small worms just need to survive. He didn't expect the coral polyps to explode here.

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

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

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

In addition, he also purchased coral algae. In fact, coral polyps cannot build coral reefs independently. In the process of building reefs, the most important helper is coral algae.

These algae are the most basic elements for the growth of coral reefs. Coral algae grow on the surface of coral reefs and can form a thin layer as hard as stone. They participate in the deposition of a considerable amount of calcium carbonate, sometimes even more than coral polyps, so they have a great contribution to the growth of coral reefs!
