Chapter 146 Underwater Rock Mountain

In the summer when the seawater temperature in the shoals rises, taking advantage of the fact that the appetite of carnivorous fish decreases due to the water temperature during this period, many small fishes will come to the shoals to lay eggs. The Shaolin found by Li Chengxin and the others is one of them.

In addition, other fish that have been caught before, such as three-line fish, puffer fish, and flat scorpionfish, may appear in this sea area to reproduce in addition to avoiding typhoons.

The large octopus that was caught and eaten before is also one of the creatures that reproduce in summer.

And now this wave of students who come to practice, one of their topics is to solve the problem of octopus reproduction.

The coastal area where Hongming Village is located was once a famous octopus production area. The octopuses here are full of nutritious food such as lobster and abalone all year round. The octopus meat is extremely delicious. I have eaten local octopus.

The open sea near Zhangba Island is one of the famous octopus breeding places in Huaguo. Octopuses play a very important role in the sea environment. Baby octopuses born on Zhangba Island will follow the currents to reach the coasts of this area. Then grow up smoothly.

In other words, if the octopus in Zhangba Island cannot lay eggs, the octopus in the entire sea area will decrease.

Zhangba Island was contracted out a few years ago and does not belong to Hongming Village, but now it belongs to Geyue Entertainment.

Li Chengxin greeted Yuan Zhao, and helped to hand in the activity plan issued by Professor Yang and the activity sea area. The Geyue Entertainment Corporation quickly approved the students from the Ocean College to practice and collect materials near Zhangba Island.

Professor Yang is very satisfied with this: "Student Li Chengxin is really easy to use!"

After contacting Li·Toolman·Cheng Xin and reporting to the Coast Guard and the staff of Zhangba Island, Professor Yang couldn't wait to rent a fishing boat and transport the students and the equipment they needed to Zhangba Island.

The film and television city of Zhangba Island is built in the inner bay, and Professor Yang is going to the outer bay.Although Zhangba Island is not very big, walking from the island, there is a mountain between the inner and outer bays, which is still far away. Tourists and infrastructure basically will not go to the outer bay.

Fortunately, Professor Yang and the students were well prepared and skilled in setting up the tent camp.

Li Chengxin, Brother Xiaoyong, and Zhou Hao also went to help, and by the way, they also agreed on a time for them to do live broadcasts and regularly replenish supplies for the students.

While Brother Xiaoyong and Zhou Hao were helping to carry the supplies, Li Chengxin was chatting with Professor Yang.

"Is it because of the weather that octopuses don't lay eggs?" In recent years, seawater temperatures have been getting higher and higher, which has had a huge impact on various marine life.

Professor Yang shook his head: "Unlike fish, molluscs such as octopuses are more active in a hot environment. Many places have seen an increase in molluscs due to rising ocean temperatures, but Zhangba Island is just the opposite. "

Originally, August and September are the breeding season for octopuses, and they will keep eating to prepare energy for reproduction.But octopuses, which are supposed to be actively courting this season, are strangely not laying eggs this year. To determine why, we need to do this research.

After the students' camp was cleaned up, Professor Yang saw that it was still early, so he decided to go to the scene to investigate.

Octopuses typically spawn in water depths above 3 meters, which is where those dive gear come in.

The topography of the outer bay of Zhangba Island is very characteristic. The rock formation is basically composed of volcanic rocks. According to research, it was formed by a volcanic eruption about 500 million years ago.There is a large stretch of rock bone in the outer bay, which is the most suitable terrain for octopus spawning.

These rock bones are a huge rock mountain 30 meters deep underwater. When the sea currents in the open sea hit the rock mountain, it will cause complex and powerful changes in the surrounding currents. Even experienced divers can easily be swept away by the current. A few hundred meters away, the worst-case scenario is that the person loses consciousness and drowns as the water hits the rocky mountain.

Every summer, there will be one or two related reports.

In order to ensure the safety of the students, the task of the first two groups of students wearing diving suits to dive was not to explore the underwater environment, but to install rivets and safety straps for fixing ropes on rocky mountains like rock climbing.

Originally, for this section, Li Chengxin planned to ask Professor Yang for the video of the students wearing Go Pro, and finally edited and played it. Unexpectedly, Zhou Hao asked to go directly into the water to record.

"How is this possible! The water flow environment is already complicated enough, don't add confusion to our subject!" Professor Yang snapped.

Zhou Hao did a few warm-up actions before going into the water: "Don't look at me like this, I have the qualification of underwater photography for more than 20000 hours."

Professor Yang couldn't believe it: "Since I have 20000 hours of experience, I should know that diving requires a partner. Among my students, there is no diver who can match your level with 100% confidence."

Zhou Hao suddenly realized: "It turned out to be the reason, I just went to the resort and called a few employees."

Fortunately, the telecommunications infrastructure of Zhangba Island is also very complete. After Zhou Hao finished making the phone call, not long after, someone drove over in a speedboat from the resort.

After introducing each other to everyone present, Professor Yang felt ashamed. These are very professional divers. With their escort, his students will be much safer.

As soon as they got into the water, several students immediately felt the difference in the water flow, and they began to wobble a little and had nowhere to focus.Fortunately, Professor Yang had already warned about the dangerous water flow in this area before, so the students didn't care, and started to work step by step, supporting the rocky mountain, communicating with each other by radio, and fixing nails at the same time.

On the other side of the camera crew, Zhou Hao, who took the camera into the water, and a diving instructor from the resort stabilized their figures in the strong current just by swinging their flippers.

Professor Yang and other divers made safety confirmation above the water surface, and at the same time held the safety cables of several people underwater with fear.

Little by little, several groups of divers in the water began to go to the bottom of the sea at a depth of 30 meters.

From the real-time images sent back by the camera, the surface of the rocky mountain is uneven. The reason for this appearance is that the volcanic ash layer of the rocky mountain is constantly washed by the water flow. This is a very perfect hiding place and a terrain that many creatures like.

At this time, Zhou Hao found a flounder estimated to be half a meter long at the bottom of the rocky mountain. The color of the flounder perfectly imitated the rock under him, and he couldn't see it unless he was careful.

Not long after, a black and white lionfish with teeth and claws was also found. The lionfish is also a kind of scorpionfish. Although it looks very beautiful, it has poisonous glands on its fin spines.

In addition, a variety of small fish such as sea bass and three-line perch were also found, as well as shells, Leiber shrimp and other crustaceans. In addition to the lush kelp and seaweed nearby, at first glance, These are all foods that octopuses like.

Theoretically, there are more than 500 species of fish and shrimps near Zhangba Island, and octopus does not lay eggs because of lack of food.
