Agriculture Idol

Chapter 246
At this point in time, although Li Chengxin was not in his hometown, the coast of his house in Hongming Village was full of excitement.

More than a dozen students ran and played on a short section of the beach. On the soft sand, they slowly buried their feet in the sand, looking for shellfish.Sandy beaches that allow feet to sink into the ankles are considered to be in excellent condition, and clams like to grow on such sandy beaches.

Judging from the situation in the small bamboo baskets in the hands of the students, they seem to have gained a lot.

Artificial beaches are not formed naturally and require some extra care during times of reduced human and biological activity, one of which is plowing.

If it is a naturally formed beach on an open coast, the waves driven by the wind will roll up the sand and keep the beach soft for a long time.In this way, marine life that likes sand can hide in it or find food.

However, the beach that Li Chengxin created by himself is right behind Zhangba Island. There are only weak sea breezes and waves all year round.In the hard sand, many marine life cannot survive.

Therefore, the soft, wet sand that now looks like it can sink gravel just by weight is indeed the result of long-term maintenance by students.

They use rakes to dig up the sand and loosen the soil, just like arable land, which is very important for unnaturally formed beaches.At Zhou Hao’s artificial beach on the other side of Hongming Village, machines are used to do this job all the year round, but the sand area on Li Chengxin’s side is too small and the sea water is too shallow. Indeed, there is no need to use large machinery.

By plowing the sand, the beach can be made soft and oxygen can enter the sand, so as to create a place suitable for fish breeding.

Of course, apart from the students, Li Chengxin's parents, the neighbor's third uncle, and villagers who have nothing to do will occasionally come to help with the daily work of this coast.

"Look! A lot of small fish are coming!" Several students who were looking for shells on the beach shouted, pointing to the sand that had just been plowed.

Professor Yang recognized it with a casual glance: "Oh, these are mullet fry, they should come to eat the plankton that has just been turned up in the sand..."

"Wow! I was shocked!" Just as he was speaking, a student pointed to a puddle on the beach and screamed.

Professor Yang, who was abandoned by everyone and was about to start a long speech, looked over and immediately recognized the creature in the puddle.

"Don't go there, it's dangerous!"

"Wait! Why is it there!"

"That's amazing."

Professor Yang leaned forward and saw that there was a red stingray in the puddle surrounded by the students: "Fortunately, I saw it. It would be bad luck if one accidentally stepped on it."

Then, Professor Yang pointed at the students and began to preach: "I told you not to run around barefoot, what should I do if I really step on a red stingray!"

Students obviously know the danger of the red stingray. It is a kind of cartilaginous fish that lives in the ocean. The stinger on the long tail is very poisonous. If you get stung once, it will cause severe pain, nausea, and difficulty in breathing. lethal.

In recent years, red stingrays have grown abnormally on the coasts of various places. The last time a few students went fishing with the villagers, they caught more than 50 stingrays in just two hours.

The students stuck out their tongues, obediently went ashore and put on their overshoes, then found fishing nets to catch the red stingray, which was nearly one meter long, and put it in the water basin beside it.

"Fortunately, red stingrays don't take the initiative to attack humans. Generally, as long as you don't step on them, you won't be counterattacked." The students are in charge of doing it, and Professor Yang is in charge of talking. "Generally speaking, if you want to catch red stingrays, you should catch them from the front. The air ports on both sides of it cannot be pierced by poisonous needles."

The students nodded, and some people tried to catch the red stingray in the water basin according to Professor Yang's words, but Professor Yang opened his outstretched hand: "Just know the method, don't try it if you have nothing to do, it's very dangerous!"

The red stingray is a dangerous creature for humans, but it is still an important existence in the marine system. After the students watched it, took pictures and recorded it, they sent it back to the sea.

Watching the red stingray swim farther and farther in the sea, some students waved their hands and said, "Next time you are caught in the open sea, you will be eaten~"

The puddle where the red stingray was in was actually dug by itself. Whenever the red stingray went to the shallows to look for clams, they were often forced to run aground on the beach. Therefore, they would dig a puddle about 10 cm deep by themselves and wait The tide is rising and this is known as a tidal depression.

The tidal depressions thus created are also hiding places for other small creatures, and since large fish cannot get close, it can be said to be an oasis for baby fish.

After seeing off the red stingrays, the students continued to check the tidal flat depressions, and sure enough, they soon found small fish among them.After finding the first one, I immediately found three or four next to it.

Carefully picked up the small fish with fishing nets, the students put the small fish into the aquarium, and then began to look through the illustrated book.

"Is this supposed to be a goby or something?"

After making an inquiry, Professor Yang confirmed from the side: "These few are indeed seedlings of gobies."

Last summer, due to the abnormal rise in seawater temperature, the previous class of students used bamboo tubes to build a hiding place for gobies on the shallow coast.The number of tidal gobies living on the coastline of Huaguo has been decreasing year by year, and it is an endangered animal.Now it seems that the gobies on the coast of Li Chengxin's "affiliated" Ocean University are successfully multiplying in large numbers.

This is the meaning of the existence of the coast of Li Chengxin's family.

In another tidal depression, a large group of seaweed is very conspicuous. Around the seaweed, the students found several small fish with sharp mouths and slender bodies.

After comparing the illustrations, the student wondered: "This fish seems to be found on this coast for the first time, and it is not in the previous illustrations."

A student next to him said: "There are only a few kinds of common fish with sharp mouths. One is swordfish...Although it is unlikely, there is another kind that is needlefish."

Needlefish, also written as squidfish, has a sharp mouth like a needle, but its belly is all black. The word "black belly" actually has a meaning derived from needlefish.Although the individuals of needlefish are not large, there are quite a lot of them, and they are common small edible fish.

After taking photos and recording, the students did not release the needlefish larvae back into the sea, but returned them to the puddle where they were caught before. This can be regarded as a protective measure.Puddles of water are an excellent hiding place for this fry.

Then, several other puddles were also found, such as flounder juveniles, mullet juveniles, sandworms, crabs and so on.It shows that the species on this coast is indeed more abundant year by year.
