After Qiubai returned to the yard, he first mixed the cement and river sand in proportion, and then left it there without caring about it, and then took Xiaobai to the river, and Ning Ning and the others also came to join in the fun.

The thick peanut vine is soft and soft, and it is very comfortable to step on it, but if you don't pay attention to stepping on it, it is really enough to choke, and the peanut vine by the river is too thick, almost a meter thick.

"Brother, do you want Xiaobai to go down to the river to see if there are any fish eggs?" Orange Orange followed, her eyes wandering around, trying to see if there were any spirit vines, and asked casually.

"Well, if there are fish eggs, it is much better to move them to the yard than to put them in the river."

The number of eggs of wild fish is very large, but the survival rate is pitifully small, there are many creatures in the water that will eat fish eggs to fill their stomachs, and even if they hatch small fish, it does not mean that small fish can grow up smoothly, small fish have too many natural enemies.

But if the fish eggs are taken care of, it will be different, the hatching rate can be more than half, with the number of hundreds of thousands of fish eggs per fish, the hatching rate is quite amazing, and the survival rate can reach up to ninety percent depending on the conditions.

"If that's the case, the space in our yard is not enough, not to mention the space in the yard, even if we expand the yard ten times and a hundred times, it will not be enough."

"Let's take a look first."

Wang Cheng usually talks a lot, but he didn't interject at this time, because he already knew from Qiubai's mouth what kind of education Chengcheng is, now college students are not rare, and doctors are not rare, but it is rare to get a double doctorate at the age of eighteen, I didn't see that Ning Ning is one of the more outstanding in their class, Ning Ning only got a doctorate, and he is seven or eight years older than Chengcheng, so Wang Cheng is a little ashamed of himself.

When he came to the river, Orange Orange put his arm around Xiaobai's neck and talked affectionately to Xiaobai for a while, and Xiaobai got into the river.

After staying quietly for a while, Ning Ning suddenly asked, "By the way, that Ning Zhigang said that there are no big fish in the Axe River anymore?" Why do we still have it in the river? Is it because of this? In the end, Ning Ning looked at Qiu Bai, meaning to ask if it was the reason for the black eyebrows.

Ning Ning didn't know about Tai Sui, and always thought it was because of the black eyebrows, and sometimes Ning Ning would carefully observe the black eyebrows, trying to see if the black eyebrows who could make such a big deal had the potential of a divine snake, but unfortunately they couldn't see why.

Qiu Bai nodded slightly, but did not speak.

Orange Fox glanced at the two of them suspiciously, always feeling that something was in the dark for her.

With a bang, Xiao Bai poked his head out from not far away and nodded to the four of them, which meant that it had found the fish eggs in the river, and it was fast.

The four of Qiubai walked over, Xiaobai dived into the water, and after a while, he climbed up with a huge peanut vine in his mouth and threw the peanut vine towards Orange Orange.

This peanut vine is almost as thick as Qiubai's wrist, more than two meters long, and its surface is covered with dense fish eggs.

These eggs are the size of pigeon eggs, there are some gray spots on the surface of the eggs, which are not too obvious, and there is an obvious black spot on the top of the eggs.

Orange picked a fish egg and held it between his fingers, put the fish egg on the top of his head and looked at the sunlight for a while, shook it and then rested it next to his ear to listen to the sound, and finally said: "Although I am a little incredible, this is indeed a grass carp egg, and it seems that these fish eggs are about to hatch." ”

Grass carp is one of the four major fish in China, and the Chinese people are familiar with it, but the spawning period of grass carp is not August, but May to June, so Orange Orange is a bit incredible, because it means that the biological cycle of grass carp has been chaotic.

Many fish will eat anything when they first hatch, plankton, juvenile fish or insect eggs in the water, and when they are older, they will slowly change their food, such as this grass carp, it will also eat small fish when it is small, but when they grow up, they will switch to eating aquatic plants, so the environment here is indeed the best hunting place for grass carp, and it is not surprising that there are grass carp infested.

For Qiubai, he doesn't care if the biological cycle of grass carp is chaotic, he cares about the fish eggs here.

This stout peanut vine is more than two meters long, sticking to the fish eggs on at least nearly a thousand, according to the hatching rate of fifty percent, that is, about five hundred, after the small grass carp hatches, if Qiubai is fed with Tai Sui water, the death will definitely not exceed one percent, that is to say, the last can grow at least four hundred and fifty, it depends on how big these grass carp can grow, if each can grow into a length of more than ten meters, the space in the yard is really not enough, too insufficient, maybe for a lake or reservoir is about the same.

"Xiaobai, are there any fish eggs down there?" Orange said to Xiaobai.

Xiao Bai nodded, and then climbed from this side to a relatively distant position, and flicked his tail, which was Xiao Bai telling everyone with his actions that the bottom of the river was full of this kind of fish eggs.

The four of them took a breath, Xiaobai's location is at least a few hundred meters away from here, and if it is full of fish eggs, it is estimated that there will be hundreds of millions of fish eggs, and they will all hatch out, well, Dongting Lake can't hold so many big fish.

Qiubai is ready to do a big job, but the site is obviously not enough, the yard has taken up all the space that should be occupied, and other people's broken houses have also been demolished, and if you want to occupy another area, you have to be a bamboo forest and other people's land, not to mention whether you can contract it down, even if you contract it, you can't build such a big fish pond.

What to do?

After thinking for a long time, Ning Ning's eyes lit up: "Orange Orange, do you say that fish can survive if they don't see the sun?" ”

"No sunlight? What does Sister Ning mean? Underground farming? It doesn't seem to work. "Orange Orange reacts pretty quickly.

Qiubai also understood what Ning Ning meant, since there is no space on the ground, then move to the underground, the ground is someone else's land, but the underground is not.

The space underneath is too vast, and it would have been whimsical to have this idea before, but now it's completely different, because there are giant beasts, and giant beasts have their own abilities, such as the pangolin that Orange Orange never forgets.

Pangolin digging holes is a good hand, just look at the name, even the mountain can be dug up, so digging rocks is not a problem, if you have a giant pangolin, then there is no problem in making a big hole in the ground, and then divert water into it, you can form a large lake, when the time comes to raise fish in the underground lake, it is much more convenient, and there is no problem of occupying land.

"Orange Orange, is it really not good? Like the last time we went to Team 10, didn't we also see a kind of fine-scale fish? The fish doesn't seem to need sunlight to survive in the groundwater. ”

"That's different, there are really fish in the ground, but this kind of fish has not evolved for countless years to survive in the groundwater, but many fish can't, like this grass carp, how to say, the role of sunlight is too great, it is difficult to explain one by one."

Indeed, the sun shines on the earth every day, but it is difficult for anyone to describe the real effect, but we should all know that sunlight, air and water are necessary for the origin and health continuation of life.

"It doesn't have to be that there is no sunlight at all, if we really breed underground, then we can open a few holes in the ground that go straight to the ground and let the sunlight shine down, so there should be no problem." Qiubai made a compromise suggestion.

"This" Orange Orange is also a little uncertain, the key is that there is no precedent.

"Oh, there's a lot of people over there." Wang Cheng did not participate in the discussion, so his eyes were the sharpest.
