Chapter 144 Luminous Insects

Soon, the underwater robot reached the controllable limit, and Li Chengxin operated to recall the robot.

"In addition to the fish photographed today, there must be more fish hiding in this sea area because of the typhoon's waves." Professor Yang asserted, "It's just that the movement of the underwater robot is still too big, so many of them are Scared away."

In order to find more fish, the students set up several fishing cages in the water according to Professor Yang's guidance, and used the leaves blown to the beach by the typhoon to camouflage the fishing cages.This is a traditional method of fishing called "cage fishing," and after sinking it in the sea, fish that prefer shady perches use it as a rock to hide in.

After the fish cages were decorated, Professor Yang sent Li Chengxin and a few students to place the fish cages near the rocky beach that the underwater robot had explored before.

Marine fish often need to find habitats, and they especially like new homes - after all, everyone likes to live in a new house.

The structural design of the fishing cage is to allow the fish to enter without exiting. Its opening is large. Along the inner structure of the cage, the fishing net will become narrower and narrower. The fish that enter are rarely able to find their entrance and escape. go out.

After setting up the fishing cages, the students put buoys on the sea surface. These buoys marked the position of the fishing cages. After a week, just follow the lines below these buoys to fish the fishing cages up again.

"Senior! This seaweed is not right!"

Early that morning, Li Chengxin heard someone calling him under the boat house.

Li Chengxin tidied up sleepily and went to the beach: "What's wrong?"

The student who called him before pointed to the seaweed net and said, "It seems that the seaweed has become less?"

Li Chengxin went over to take a closer look: "Hey, it's really... There is no seaweed left on this line..."

A few days ago, there were fluffy purple seaweeds about three centimeters long on the seaweed net. Today, I saw a large piece of bald seaweed on the seaweed net.

"It seems that after the typhoon, too many fish from other places came to this sea area and ate the seaweed." Li Chengxin made a judgment.

After all, seaweed is very nutritious and delicious for all kinds of creatures, not only fish, but also birds that eat seaweed for a living, and of course humans, otherwise why would they grow seaweed at home.

Li Chengxin went to Professor Yang to borrow an ordinary underwater camera, fixed it near the seaweed net, and pointed the lens at the bottom of the seaweed net.

After waiting for an hour, the student in charge of staring at the screen noticed that a fish had quietly approached.

In the shot, a large black shadow slowly approached from a distance, and the black shadow that appeared from far to near in the green sea water seemed to be the appearance of the villain.Then, the black shadow pecked hard at the seaweed net.

"Isn't this the black snapper that was spotted by the underwater camera a few days ago?" Everyone recognized the criminal who stole seaweed.

"Isn't black sea bream a carnivorous fish? They still eat seaweed?"

"Who said black snapper is carnivorous?" Professor Yang appeared behind the crowd, "Go ahead and read a chapter, it is clearly written that black snapper is omnivorous, and the main food is molluscs, shrimps, crabs, and amphipods. Starfish and algae, etc."

"Ah, black snapper, I want to eat it!" Li Chengxin changed the topic with a dry smile.

It's just that the black snapper was very cautious. When Li Chengxin appeared on the sea with a fishing net, the black snapper flicked its tail and ran away quickly.

You can’t catch the fish, but you can use the timidity of the black snapper to set up a sea “scarecrow” to drive the black snapper away.

The biggest natural enemy of black snapper is seabirds, which are very sensitive to shadows on the sea surface.

After knowing this feature, a few students worked together to cut out some hideous bird shapes with thin wood boards picked up on the beach.

These bird-shaped wooden boards are mounted on bamboo poles to make fan blades that can be driven by the wind, and then inserted in the center of the seaweed net.

From the perspective of the underwater camera set up before, the fan blades that rotate slowly with the sea breeze really look like seabirds hovering above.

Theoretically, in two weeks, nori will be ready for harvest.

Before that, the fishing cage set up a week ago can also be collected.

Li Chengxin, who was rowing a small sampan to collect the fishing cages, obviously felt that the cages were much heavier than before putting them down, so there were only a few left and they simply exchanged jobs with Zhou Hao.Li Chengxin came with a live broadcast camera and asked a muscular man like Zhou Hao to do the physical work.

【Wow!It's been a long time since I saw the photographer on camera! 】

[Handsome photographer, here are two more fitness sets! 】

[The scene of a muscular man fishing is really beautiful b (￣▽￣)d]

Indeed, when the fishing cage is pulled up, Zhou Hao's tight biceps are indeed worthy of making people lick the screen.

But today's focus is not on muscles, but on fish traps.

Through the leaves decorated outside the fishing cage, netizens in the live broadcast room saw that there were indeed some fish inside.

Open the fishing cage directly on the small sampan, pour out the fish, and then flatten the fishing cage and put it away.

Starfish, crabs, puffer fish, sea cucumbers, scorpionfish...we did catch a lot of species.

Li Chengxin began to introduce them one by one.

"This is the yellow starfish, whose scientific name is Spiny Sea Star. It is a very common starfish along the Yellow Sea coast of my country. It can be eaten."

"This is a stone crab, from the swimming crab family, delicious!"

"The scientific name of this pufferfish is pufferfish. It swims slowly. When it is frightened, it will inhale a large amount of air or water and swell the fish into a ball to scare away predators... Take it back to the town and find a chef with a puffer fish processing license." Just process it and eat it."

"Let me take a look at the scorpionfish. It is the brown calamus, also known as Shigougong and Shijiugong. It is a species of ray-finned fishes, Scorpioniformes, Scorpionidae, and Scorpionidae. It is an oviparous fish and is also an edible fish. Hehe .”

"This scorpionfish looks similar to the brown squid, but the color is still slightly different. It is a thick-headed flat scorpion. They are close relatives. As long as the spines with poisonous glands are removed, they are delicious when stewed or grilled... ...Hey, that's not right, this fish has a bulging belly, and it is probably pregnant, so according to various conventions, I had to release it." Saying this, Li Chengxin carefully put the pachycephalus back into the water.

……

After the students recorded the fish caught in the fishing cage one by one, everyone enjoyed another wave of the freshest seafood feast.

In the evening, the students who were full and the children who came back from the summer vacation in the village played with water on the beach to digest their food.

"Wow! The night light bug is here!"

Hearing the shouts of joy from the beach, Li Chengxin, who was washing the pot, looked up at the beach.

I saw a circle of fluorescent blue around the people standing in the water, and even every wave was fluorescent.

In order to make these blue fluorescent lights appear, everyone started to fetch water even more excitedly. The seaside was full of blue, especially beautiful under the dark orange background sky.

There are also children who filled seawater in glass bottles and waved them in their hands. With the children's movements, the fluorescent blue in the glass bottles flickered.

The one that emits blue fluorescence is a kind of phytoplankton called "noctilucent insects". They have a luminescent substance called luciferin in their bodies, which is similar to fireflies, and they will emit blue fluorescence after being stimulated by the outside world.

On summer nights with constant sun exposure during the day, every spray turns a bright blue.

The longer the sunshine time, the more plankton there will be, which is probably one of the reasons why the mullets that used to eat plankton came here.

This is one of the scenery that can be seen occasionally in summer in the waters near Hongming Village. This scene is also known as the aurora in the sea.

Since the red tide occurred last year, Xiao Jia, the resort's marine consultant, has been monitoring the seaweed populations in the nearby sea early in the morning, and also knows that nocturnal lights have begun to multiply.

For this reason, Zhou Hao's resort has already started advertising, attracting many tourists. After the aurora in the sea is confirmed to appear in the past few days, there should be more tourists coming.

Coincidentally, sea urchins are also harvesting, and Zhou Hao has already ordered a large batch for his resort.With the right time, place and people, the economy of Hongming Village will not be bad this year.
