Chapter 138 Fish Survey Night Edition

When Geyue Entertainment took advantage of Li Chengxin's four concerts to hit the charts for his new album, he himself had already returned to Hongming Village in Zhou Hao's unremarkable car.

After passing the resort, Li Chengxin naturally went in first to say hello to his parents.

"Why did Xin Wa'er just come back? Your school's teachers and classmates have already arrived!" Li Chengxin's parents asked about the child's recent situation, then kicked him out of the workplace and asked him to go home early to entertain guests.

A row of tents have already been set up in the yard connected to the beach under the houseboat of my house. A dozen young people are busy arranging supplies. Professor Yang of the Ocean College and his proud disciple Xiao Jia who stayed in Hongming Village are on the side. Look through the information.

"Professor Yang, you're all here!" Li Chengxin stepped forward to say hello, and while helping Zhou Hao unload luggage and various gifts from the car, he handed Professor Yang a big fruit basket first.

Professor Yang took it with a smile, and asked a student to share the fruit, and then skillfully arranged work for Li Chengxin, asking him to guide a few young students to familiarize themselves with the coast.

"Senior! Please sign!" A female student took advantage of Professor Yang not paying attention and handed over a CD of Li Chengxin's new album.

Li Chengxin glanced at Professor Yang and saw that the professor was not paying attention. He quickly took out a marker and signed the CD. The female student ran away shyly with satisfaction.

"Senior, what is that?" Another student pointed to a large-hole fishing net fixed on the sea and asked.

Li Chengxin went over to take a look: "Oh, this is the seaweed grown by myself."

"Then what is hanging on the net?" The student continued to ask. This attitude of breaking the casserole made Li Chengxin think of himself when he started the live broadcast of helping farmers.

Li Chengxin followed what the student pointed out and saw that there were a few small net bags hanging under the seaweed net, and there were shells inside.

That is the "parachute method" used to attach the nori spores to the nori net.

Due to the previous sea urchin infestation, there are many empty shells of dead oysters on the bottom of the sea near Hongming Village, and seaweed spores often adhere to them. If you pick up an oyster shell with green inside, the green ones are not dirty things, but seaweed spores .

The oyster shells attached to the seaweed spores are hung under the seaweed net in a small net, and the seaweed spores will adhere to the seaweed net made of nylon rope along with the water flow and begin to germinate and grow.The spores that leave the oyster shells that sink on the seabed and attach to the net of seaweed can grow several millimeters a day.

Li Chengxin checked the light-colored seaweed network cable, and easily found the light purple seaweed that had begun to grow.

In the eyes of unfamiliar people, this is just a stain on the Internet.

"This is how seaweed is grown!" The student suddenly realized, "Can this net be moved? We may need to set up a net in this area to fish at night."

Li Chengxin nodded and said "no problem", paddled the small sampan, and moved the seaweed net to a place a little further away with a few students. After two days, the students finished their tidal flat research and moved it back to the original place. become.

At nine o'clock in the evening, the business started, and Zhou Hao also skillfully set up the night scene camera.

"Okay, let's start setting up an Internet cafe."

Like last year, Professor Yang's first job is still to use lights at night to attract fish to approach, and then confirm the types of offshore fish in this sea area.

But what is different from last year is that this time more students participated in the internship, and the fishing nets laid were even larger. A pulley block was set up on the coast using tripods, which made it much more convenient to collect the nets than before. The net moves away.

Li Chengxin also put on overshoes and walked on the tidal flat to help lay the fishing net. The 12-meter-square fishing net was spread out flat, almost a quarter of the size of the experimental coast, and the fish that were attracted had to be caught in the net in the end. this ending.

Last year, the fishing method of "catching fish" with small nets was used, and the effect was also good. However, in order to enrich the teaching content, this year, the "netting method" of large fishing nets was adopted.

Set up ropes with pulleys at the four corners of the fishing net. The high-power searchlights point directly at the center of the fishing net. Professor Yang, a marine expert, stands on the second floor of the boat house to conduct observation and command. Can catch everything.

"Although spring is actually the best season for observation, there are also a lot of fish in summer. Because the statistics were done at this time last year, we will continue to choose this time period this year, so that we can make comparisons."

Professor Yang explained the theoretical knowledge to Li Chengxin, the students, and the netizens in the live broadcast room.

As seawater temperatures rise in summer, plankton continue to bloom in large numbers, so small fish hunting for food will gather, and then large carnivorous fish will follow the small fish.

Two hours after the fishing net was laid, the tide overflowed the fishing net, and the naked eye observed fine air bubbles on the surface of the water, which were small fish swimming in groups.If you look carefully, you can see small fish swimming in groups under the light, jumping out of the sea from time to time, and casting a silver light under the light.

【A lot of fish!Feels like an aquarium! 】

[Haozi is really rich, the quality of this night scene camera is really good]

【I want to eat small fried fish ˋ(°▽、°)! 】

The angle of view of the camera is switched to the underwater camera set above the fishing net. From this angle, densely packed small fish swim in the water above the fishing net.

Li Chengxin introduced casually: "These are basically mullets, that is, mullets, which are economic fish in the middle and upper layers of warm and shallow seas."

The student next to him was surprised: "These reflective spots are all mullets? How many should there be?"

"Like a flying fish, looking at it makes one's scalp tingle."

Hearing the discussion among the students, Li Chengxin's parents, who came over to entertain guests with homemade snacks, also came to the shore to watch.

Li Chengxin’s father said longingly: “I haven’t seen such a scene in many years!”

The villagers watching the students work also nodded: "This may be the largest group of mullets in the vicinity, and they all came here."

Mullet is a common economic fish found in coastal waters all over the world. Because it can continue to survive in polluted seas, it is very easy to find.But of course, mullet from clean waters tastes better.

Mullets originally like algae that grow in clean tidal areas. There are no tidal flats near Hongming Village, but Li Chengxin’s coast and Zhou Hao’s resort have created artificial beaches. There is a tidal flat, so the nearby mullets may gather.

At this time, Professor Yang who was on a high place suddenly said, "A big guy has come in! Pull the net! Pull the net!"

The students who had been prepared to stand by the pulleys began to pull the net together.

When the four corners of the fishing net were pulled up and the fish in the net had no possibility of escaping, Li Chengxin took a small net and put it into the net.

Before I found the "big guy" that Professor Yang mentioned, I first saw a few red jellyfish floating on the sea.

"Is this a jellyfish or a red jellyfish?" Li Chengxin asked.

The system answered him one step ahead of Professor Yang: [Red jellyfish, the canopy has reddish-brown stripes, and the tentacles are very poisonous]

QAQ...

Li Chengxin put on the thick rubber gloves stuffed in the breast pocket of the waterproof suit, and carefully put the three red jellyfish in front of him into the fish tank handed over by the student.

Among the long tentacles of the red jellyfish, there are countless capsules wrapped with toxins, and the toxins will be released when a little external force is applied.

Professor Yang took a severed tentacle and placed it under a microscope for students to observe.

In the microscope, the 0.01mm venomous spine protruded from the surface of the tentacles, shaking in the water droplets, and the toxin was scattered.

"Even if it is a fish, if it accidentally swallows the broken tentacles, it will basically not survive. The symptoms of human beings after poisoning are red rashes, which can lead to breathing difficulties in severe cases." Professor Yang is not only teaching students, but also Teach hundreds of thousands of netizens in the live broadcast room.

At this time, a student found a silvery thing inside a jellyfish, turned the angle of the fish tank, and everyone saw a small mullet wrapped under the canopy of the red jellyfish.

【Wow!Amazing! 】

【This is too scary! 】

[I always thought that jellyfish eat plankton...]

"The small fish can easily get entangled in the jellyfish's tentacles, then get stunned, die, and be digested by the jellyfish."

　I am addicted to the animal forest and cannot extricate myself.
