Listening to Lu Zhizi's words, Ao Muyang was stunned: "What do you need?

Lu Zhizi ignored his questions and replied to himself: "I checked some information, because the corals are almost fixed, so they are not good at searching for food, they can only filter the surrounding water, waiting 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 stiffened his face and said, "When the teacher is lecturing, students are not allowed to interject indiscriminately. ”

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, and if you encounter a problem, you have to ask questions, okay, now I'll solve your problem." ”

After thinking for a moment, she organized her words and said, "Continuing with what I just said, in order for polyps to draw nutrients from the surrounding seawater, they must first have ingredients to absorb. Fish account for a large proportion of the nutrient sources needed by coral reefs, and they are mobile nutrients for polyps. ”

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

In order to allow the polyps to eat as many small golden droplets as possible, he drove away the fish, and later found that the polyps were not active, and he did not dare to let the fish get close to the polyps, for fear of affecting their vitality.

According to Lu Zhizi's meaning, Ao Muyang's doing this is counterproductive.

Lu Zhizi nodded and said: "Dr. Orgeye, an Australian oceanographer, led a team to study the symbiosis of coral reefs and fish schools in many places. ”

"The relationship between the two sides is symbiotic and mutually beneficial, such as the coral reefs in the Caribbean, where large fish use the reef as a refuge during the day and a hunting ground at night. They naturally secrete ammonium, a nutrient necessary for coral reef growth, through their gills, and phosphorus, which is another key nutrient in the fish's urine. ”

"Of these, fish urine is the most important for coral reefs!" she accentuated the sentence.

Ao Muyang smiled and said, "Is this research reliable? If so, I'll get some urea for the polyps." ”

Lu Zhizi glared at him: "Don't be hippie, Dr. Orgaye investigated 150 species of fish in 43 different coral reefs in the Caribbean Sea, and found that the nearby coral reefs with more predatory fish have a richer diet and are more active. Coral reefs with fewer fish lack some essential nutrients, and the fewer fish they have, the less active they are. ”

Ao Muyang said: "I understand what you mean, in short, this last sentence is the point, if the polyp wants to be vigorous, it must survive with the fish." ”

Lu Zhizi snapped his fingers and said, "Completely correct." ”

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

His face was inexplicable.

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

Ao Muyang took the magazine and looked at it, and the cover was a few letters: "Nature".

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

If Lu Zhizi had obtained information from the journal Nature, he would not have had any doubts, the world's first international scientific journal that has consistently reported and commented on the most important breakthroughs in the global scientific and technological network since its inception in 1869.

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

In order to protect the polyps, he also used nets to cut the living quarters of the polyps independently, separating them from the fish school very thoroughly.

As a result, he did the opposite.

Finally, he asked, "In addition, you just said that it has something to do with whale urine, but the research you said later has nothing to do with fish urine." ”

Lu Zhizi said leisurely: "This involves another feasibility study report, do you want to listen to the detailed version?"

Ao Muyang immediately decided: "No, I want to listen to the summary version." ”

Lu Zhizi smiled slightly and said, "The summary version is that whale urine is the most nutritious in fish urine, and in addition, they also have the largest urine volume. ”

Ao Muyang touched his chin and said: "I don't think it's appropriate to use whale urine to water polyps, their urine may be rich in nutrients, but the so-called too much, in the case of traditional Chinese medicine, eating too much nourishment to make up for it is more terrible than eating poison." ”

Lu Zhizi pursed his lips to speak, Ao Muyang hurriedly said: "Really, there was a grape planted at the door of Fugui's house before, and we wanted to eat grapes early, so the friends made an appointment to pee and fertilize the grapes together, but as a result, they died in two days!"

"This grape is so pitiful, it actually touched you," Lu Zhizi laughed and said, "But those polyps in your fishing ground, I'm afraid they are already crazy with lack of nutrition!"

Ao Muyang finally agreed with Lu Zhizi's words, and he returned to the fishing ground to remove the isolation net first, and then shook off a little gold drop.

Immediately, large yellow croaker, treasure fish, sole, and tuna came together, and the momentum was violent.

There is also one of the most ferocious, and that is the tiger.

The killer whale is a large baleen whale, the tiger's urine volume is very strong, and it can spray three meters against the current, if it turns over and pees on the surface of the sea, it will be like a small fountain!

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

As a result, he racked his brains for a while, but he couldn't figure out how to make the tiger understand the idea of asking him to pee......

Lu Zhizi's advice was very effective, and the activity of the corals began to improve as the fish began to approach the corals.

They are still not as energetic as they are in incubators, but they can already swing their tentacles to hunt, and their colors have 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 didn't expect polyps to break out here.

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

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

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

In addition, he also bought coralal algae, in fact, polyps do not build coral reefs on their own, and in the process of building reefs, the main helpers are coralal algae algae.

These algae are the most essential elements for coral reef growth, corals grow on the surface of coral reefs, can form thin layers as hard as stones, they participate in the deposition of a considerable amount of calcium carbonate, sometimes even more than polyps, and therefore contribute greatly to coral reef growth!
