318. The good helper (3)
"There is a tuna in the fishing ground." Ao Muyang told Lu Zhizi the news.
Lu Zhizi was suspicious: "Real or false? How is it possible? Can you still raise tuna?"
Ao Muyang said: "Wait, I'll put on you in a deep diving suit so that it can resist the cold. Then I'll take you to the water to see, there's really a tuna!"
Seeing his serious expression, Lu Zhizi believed his words and looked surprised: "Then you must see, hasn't the problem of artificial breeding of tuna been overcome yet?"
This tuna does not have deep diving, so they just need to dive on the surface of the ocean. The reason they have to wear deep diving suits is because the deep diving suits are the warmest.
Ao Muyang still dressed up simply, Lu Zhizi said, "Don't you think you're cold?"
"I have strong firepower." He patted his lower abdomen and smiled very flirtatiously.
The two dived into the water and waited around an oxygen generator.
Not long after, the majestic figure of the Bluefin Tuna appeared.
It wandered around the oxygen generator for two minutes, swimming in a spiral shape, and started swimming in a deeper and slower speed. Finally, when it came to the oxygen generator, the slowest speed.
Then, it left the oxygen generator and went to the next oxygen generator, dived again, and at the same time, speeding up again and gradually speeding up until it swam next to an oxygen generator, and then repeated the process...
Lu Zhizi floated out of the water and exclaimed: "Really, this is really a tuna, or a bluefin tuna. I have seen it in Boston, but I have never seen it live!"
Ao Muyang was proud and said: "How is it, it's amazing. I have a bluefin tuna!"
Lu Zhizi said excitedly: "This is amazing. Where did you get this bluefin tuna?"
Ao Muyang lied: "Did it jump in by itself? I don't know. Anyway, I came here this time and found this fish. I was shocked at that time. I probably jumped in from outside. After all, there are many fish fryes in this fishing ground, and for them, this is all food."
After thinking about it, Lu Zhizi said, "If this is the case, there should be bluefin tuna around, and they often like to walk in groups."
Ao Muyang said: "The others may have left, right?"
Lu Zhizi said: "Wait first, I'll recall some information about tuna."
She swam back to the shore and said slowly: "This season, bluefin tuna should have gone to the southern hemisphere. They are subtropical and tropical fish. They will go to the southern hemisphere in winter and then migrate and spawn in spring and summer."
Ao Muyang knows that most fish, like snakes, are cold-blooded creatures, that is, their body temperature will change with changes in the external environment, but the ocean temperature is relatively constant all year round, so their body temperature does not change much year round, unlike the cold-blooded species in mammals that need to migrate in winter or hibernate in winter.
But tuna is one of the few hot-blooded species among fish. Their body temperature can reach 34 to 36 degrees Celsius, especially the muscles and skin on both sides of the spine, which makes them metabolized particularly vigorously.
In this case, in order to better preserve heat, they like relatively high water temperatures and tropical environments.
Lu Zhizi continued: "This tuna appears around in winter, indicating that there is a hot water temperature around, or that there is a warm current here!"
Ao Muyang nodded: "You are right. I found that there is a warm current here, so I built a fishing ground here."
Upon hearing this, Lu Zhizi snapped her fingers: "That's right, I remember that tunas have a habit. Although they can sail for a large mileage throughout their lives, they can stay in a comfortable environment for a short time."
"They also have another habit, which is that they like the tendency of floating objects on the sea to gather. We can use this habit to find out if there are other tunas in the sea."
Ao Muyang asked: "What is the gathering trend of floating objects on the sea?"
He didn't know this, he only knew that the first half of what Lu Zhizi said was that tuna could stay in some environments for a short time.
For example, the yellowfin tuna in the Pacific Ocean, this fish will swim to the edge of ocean islands with coral bushes during the day, and then go to the near sea at night, and return here in the early morning, constantly migrating in a sea area...
Lu Zhizi explained: "It is when tuna finds something floating on the sea, such as wood, plastic fragments or some float, and then they will gather in this place for a while."
"They still have this habit?" Ao Muyang heard of it for the first time.
Lu Zhizi nodded: "Yes, scientific explanations, these floating objects make the sea surface full of three-dimensional space. Tuna swims next to these objects to find reference objects to determine coordinates for their voyage, so as to correct the navigation route."
"It seems like that," she wasn't sure, and she continued, thinking about it for a while, "it should be right. When I was in Boston, some tuna anglers would use this to lure tuna. They artificially create floating objects on the sea to attract tuna."
There was already an Internet signal on the island, so Ao Muyang checked the Internet and found that Lu Zhizi was right.
The information was verified, and Lu Zhizi had an idea: "We go to find the warm waters in the ocean, and then create some floating objects near the warm waters, which may attract tuna."
This idea is good, Ao Muyang immediately said: "I know the waters where the warm current flows through, so let's prepare floating objects."
Lu Zhizi said, "Don't hold too much hope, maybe as you said, this fish have left here."
Ao Muyang was not worried about this, because he had seen this fish just half an hour ago.
It was very simple to make floating objects. He found some wooden boards to tie them with floating balls, put them on the sea together with the raft and sea fishing boat, and made a large floating body.
The next step was to wait patiently. The wind was strong at sea. He asked Lu Zhizi to go back to the house to read a book and rest, and waited on the sea fishing boat.
After Lu Zhizi left, he jumped into the water. There was water vapor and warmth in the water, which was so comfortable.
He equipped the tiger with saddles, and if there were any tunas, they would attack together.
In order to enhance the temptation of this floating object, he also tied a lot of squid, squirrels, and fish meat sections around him, which are all tuna foods to enhance the temptation.
As soon as he finished his work in the water, the motorboat suddenly came over. He knew that it was Lu Zhizi on it, so he quickly turned over to the boat.
Lu Zhizi didn't ask him why he kept soaking in the water, and said directly: "Mobile phone, Mr. Yan from the blue boatman is looking for you and said he is looking for you to help! Please pick it up quickly, but you haven't hung up yet!"
Ao Muyang quickly took the phone and asked, "Hey, Mr. Yan, Zhu Zhu was kidnapped again?"
"No, Xiao Ao, come to the municipal hospital, Zhu Zhu is sick, God! Come and save Zhu Zhu's life!"
