Chapter 145 Yellowfin Goby
At the beginning of September, at the end of the end of the summer season, the three volts are coming to an end, but the weather has become abnormally hotter.

Brother Xiao Yong's outdoor martial arts scenes that were scheduled to be filmed during this period were also suspended. Taking advantage of this unexpected break, Brother Xiao Yong sneaked back to the village, planning to spend time with Lin Yiyi.

"Why are there so many people here?" Brother Xiaoyong stared at Li Chengxin's shore in bewilderment, "Is it time for the student department to go back to school?"

Li Chengxin spread his hands: "Those undergraduate students who were interns in the previous summer have all gone back. This group is the graduate students and doctoral students who came here to complete the school's internship courses."

Brother Xiao Yong took a closer look and found that indeed, the group of people setting up tents and packing equipment on the beach now looked much more mature than the previous batch of freshmen and sophomores. There were more and more professional diving equipment on the beach than before. up.

Just as they were talking, one of them trotted over to report to Professor Yang who was writing under the eaves of the boat house: "Mr. Yang, the water temperature is abnormally high. Not only is it not suitable for diving, even the fish have no strength to swim."

At the beginning, when he said that the water was too hot to dive, Professor Yang didn't care too much. Even if he didn't dive, there are many other things to do.But the next moment when he mentioned that fish were also injured, Professor Yang immediately put down his computer and stood up.

"What's going on? Take me to see it!"

The man took Professor Yang to the beach, Li Chengxin and brother Xiaoyong naturally followed to watch the excitement, Zhou Hao also followed with the camera on his back.

There were a few students gathered around, pointing in the water, and when they saw Professor Yang approaching, they immediately gave up their seats.

"Professor, that's right there." The student leading the way pointed to the clear, shallow sea with calm waves, and you could easily see every pebble on the underwater beach.

The student pointed to a light brown fish with spots lying on the bottom of the beach.

Even without using the system, Li Chengxin easily recognized this fish: "Yellowfin goby is a small warm-water nearshore fish that inhabits shallow seas with silt and sandy bottom... It is also delicious... ...but this one is a little small."

Li Chengxin compared and found that it only grows to the length of a finger, and gobies only grow up to 30 centimeters, which is not enough to eat now.

"Hey, that's weird, why don't you run away?"

Gobies are generally very vigilant, and as long as they get close, they will use their tails to raise a cloud of sea sand and run away.

This time, the finger that Li Chengxin used to gesticulate the length almost hit the goby, and it didn't run away.

Li Chengxin stretched out his finger again and poked the goby, but it only ran forward a little bit.

Under the reminders of the students, Li Chengxin found that there was more than one such yellow-fin goby, all of which were slow-moving and unresponsive.

Professor Yang pushed Li Chengxin away and observed the goby: "This fish is breathing very rapidly, which seems to be a response to lack of oxygen. It should be because the water temperature is too high."

The student before said: "Yeah, I was talking about this just now. The sea water temperature in the shoal here is actually 28 degrees."

Professor Yang checked the previous records and found that the seawater temperature during the same period last year was only 26 degrees.

It may seem like a difference of only two degrees, but it can really kill a fish.

Fish will change their body temperature according to the water temperature. If the water temperature is too high, the temperature of the fish body will also rise excessively. Even if the human body temperature rises by two degrees, accidents will definitely happen.

The increase in body temperature of the fish will lead to faster breathing and decreased appetite. Coupled with the decrease in dissolved oxygen in seawater at high temperatures, the fish will have difficulty breathing, become weak, and in the worst case may lead to death.

In this regard, Professor Yang issued a task to several students, asking them to come up with ways to cool down the yellowfin goby.

Compared with those undergraduate students before, Professor Yang did more guidance and explained all the problems in detail; for the current graduate students and doctoral students, Professor Yang began to ask them to think of solutions by themselves.

Several students gladly accepted the order, and soon after, they each researched a few proposals and took them to Professor Yang for defense.

After the final plan was finalized, the students came to ask Li Chengxin for help.

Not really helping, just providing some bamboo poles upon request.

The bamboo poles in Li Chengxin's house were all prepared by Brother Xiaoyong in recent years, and they are also raw materials for repairing various floating platforms on the sea.

Hearing that bamboo poles will be used, Brother Xiaoyong also came to help. He is a small construction expert in the village.

Although the students proposed a plan, as city dwellers, they are not very good at manual work. This was demonstrated when they made a black snapper expulsion device for Nori.Therefore, the students are eager for Brother Xiaoyong to help.

The bamboo poles are the thickest ones, and they are sawed into bamboo tubes about 30 centimeters long, and the partitions at the bamboo joints need to be knocked off.

Arrange the prepared ten bamboo tubes into a pyramid shape like billiard balls, and fix them with ropes.

"This should be enough." The students took a few piles of bamboo tubes like this that Xiaoyong helped them make and went to the sea. "In this way, the bamboo tubes can provide a good shade for gobies."

Put the pile of bamboo tubes into the central area of ​​the coast, and then cover the top and vicinity of the pile of bamboo tubes with nearby live rocks to conceal and fix them.

In this way, there are some shaded places on the tidal flats that were originally exposed to the midsummer sun.

In addition, the students set up cameras and thermometers that can transmit data in real time next to the pile of bamboo tubes.

Soon, the students withdrew from the underwater construction area, hid in Li Chengxin's boathouse and monitored the situation in that area with the air conditioner blowing.

The sand and gravel raised by human activities gradually settled down, and the temperature nearby gradually stabilized.

"It really works!" A student looked at the temperature displayed on the screen and cheered, slapping his thigh.

The water temperature outside the bamboo pile is still 28 degrees, but the water temperature inside has dropped to 26 degrees, which is a comfortable temperature for yellowfin gobies.

Soon, the yellow-fin spiny goby that had been patrolling nearby entered the picture transmitted by the camera. After swimming twice vigilantly, it flicked its tail and entered the bottom bamboo tube of the pile.

【Great! 】

[Is this really not a posing? 】

【The man above, how can fish be posed for a photo...】

"Should this be used to write a thesis?" The students talked a lot.

"Wait a minute, there's not enough data for one fish."

After nearly half an hour, several gobies have gathered near the bamboo pile, and the gobies occupying the first layer of the bamboo pile have obviously regained their vitality, and even began to expel other gobies who wanted to enter the bamboo pile .

"It seems that this plan is still flawed. Gobies are bottom-dwelling fish. They only like the bamboo tubes at the bottom, and no fish care about the bamboo tubes in the upper layers."

"Yes, so in fact, we should put only one layer of bamboo tubes, and more stones can be placed on top to create a hiding place."

Continuing to monitor the situation near the bamboo pile, the students found that among the fish waiting to enter the bamboo pile for summer vacation, there were even a few endangered fish species similar in size to the goby with few scales. With dazzling brilliance.

Shaolin has never appeared in the waters near Hongming Village before, and they will spawn in the shallows in summer. It seems that Li Chengxin's coast is very attractive to many fish that like clean sand and gravel.
