Chu Jiaqiang took the duck egg, glanced at it, and immediately said, "This duck egg is bad and can't be eaten." ”

"Huh! How so? Although the shell has some signs, it can't be so arbitrary? If you don't knock it out and take a look, no one is 100% sure? Zhou Furong said.

"That's a good judgment! I'm sure it must be a badass. The shell of a good egg is fresh and has a layer of hoarfrost. If the head shines on the shell of a white egg, that is, the egg that has not been fertilized after two or three days of incubation has a large stomata; The shell of the eggs has gray-black spots, which are due to rain or moisture. The shell of the rotten egg is black. Chu Jiaqiang said affirmatively.

In addition, there are other ways to judge. The fresh egg is heavy in the hand, and there is a feeling of pressing the hand. White eggs are smooth and lightweight. The shell of the black paste egg and the moldy egg is astringent.

Or, hold three eggs in your hand and touch each other, commonly known as shaking eggs. The sound of good eggs is real, like the sound of hitting bricks, the sound of holes in the big empty heads, the sound of "popping" of cracked eggs, and the sound of sticking preserved eggs and rotten eggs like knocking on rubble.

If possible, fluorescent lamps or lights can be used to take care of them. Good eggs are translucent, rotten eggs are black, and scattered yellow eggs are like clouds. The red skin is partially red, the black skin is partially black, the epsom yellow egg is blurred, the yolk of the heat wound egg is expanded, and the air chamber is large.

Of course, people with a smart nose can also smell the smell, fresh eggs have no peculiar smell, fresh duck eggs have egg smell, such as eggshell mildew, or stinky is moldy eggs or bad eggs, gasoline, pesticides and other odors are polluted eggs.

"If you don't believe me, put it in the water. Eggs that sink to the bottom of the water are good eggs, half-sinking and half-floating eggs are old eggs, and those that float on the surface of the water are spoiled eggs. Chu Jiaqiang said to him.

Hearing this, Zhou Furong suddenly had nothing to say and threw away the duck eggs. When I picked it up just now, the duck egg was floating on the water, otherwise it wouldn't be so easy to find.

"Hehe, you're an unlucky guy." Li Quan teased. Just now, Zhou Furong looked so proud, he wanted to hit someone.

Several people were talking. While working, I don't feel hard at all, and the cool breeze is gusting, I don't know how comfortable it is!

"Oops! There's a big yellow eel here, so come here. It didn't take long for Li Quan to suddenly shout loudly. But he made such a big noise. The yellow eel shrank into the eel cave at once.

"Where? You liar! Zhou Furong and the others walked over. found that there was no shadow of the yellow eel, and thought that Li Quan's guy was a liar.

"What are you lying to? I was shocked by my voice just now, and I have slipped into the cave, you see, this is the Yellow Eel Cave, I just saw it retracted with my own eyes, is this still fake? I'm not that bored. Li Quan immediately explained.

Chen Wu and the others immediately disappeared, and they pointed to a small hole and said this, seamlessly. What else can I say? Is it true, who knows? You can't see what's going on inside.

Chu Jiaqiang also glanced at it, it was indeed the Yellow Eel Cave. Generally speaking, there are only two places where eels can hide. One is the mud hole he drilled himself, which is generally 1-2 meters deep, and the hole will not be straight. Sometimes the hole also forks. The other is natural, such as stone caves and stone crevices, which is not certain.

"Poke your finger in and see." Li Quan saw that they still didn't believe it, so he suggested.

Chu Jiaqiang hurriedly stopped: "Don't, don't be afraid of biting, just stick in!" At this time of summer, many eels are spawning. At this time, the yellow eel is very fierce. If you find a yellow eel burrow, and you put your hand in it, there's a good chance that the yellow eel will bite you. ”

His words are not to scare people, and the yellow eel bites people very powerfully. Chu Jiaqiang had tried to be bitten by a yellow eel before.

Perhaps, in the eyes of many people, the yellow eel is a bit of a "hermit" bearing, without special attack skills, nor strong defensive weapons, the only skill is "thirty-six strategies, escape is the upper plan".

What's more, they secrete a very oily mucus all over their bodies, and if you're not careful, they can slip out of your hands. In fact, the main functions of the mucus on the eel are: to prevent bacteria and germs from infecting the body and reduce diseases; Prevent the entanglement of parasitic animals and plants, which is conducive to growth; The smooth surface of the oil head is conducive to its passage in the mud without hindrance.

But those who really know the yellow eel will know that the yellow eel has a lot of sharp teeth, and biting people is no joke.

"Don't look at it, this is indeed the Yellow Eel Cave." Chu Jiaqiang said to them.

"How do you know?" Chen Wu and the others immediately asked, just now, Chu Jiaqiang didn't see the yellow eel slipping in, just a small hole, it doesn't make sense?

"Another easy way to find eels when they hatch their eggs is to have a circle of tiny white bubbles about 10 centimeters in diameter on the surface of the water at the entrance of the cave. Look there, are there white bubbles? Chu Jiaqiang pointed to the white bubbles in the circle and said.

Yellow eel lays eggs near the entrance of its burrow, spits foam into a nest before spawning, and the fertilized eggs develop on the water surface with the buoyancy of foam in the foam, and both male and female fish have the habit of protecting the nest.

"I see! If you didn't have this circle of bubbles, would you still be able to tell the yellow eel hole? Li Quan suddenly asked.

"Why not? In the past, when you often fished for yellow eels, you had to know how to judge the yellow eel holes. Chu Jiaqiang replied.

Later, I told them some ways to judge the yellow eel hole: "The yellow eel is in the water, and it generally burrows in the soft mud or burrows in the natural mud hole or stone cave, so the first thing to find when fishing for the yellow eel is to find the yellow eel hole." Yellow eel holes are mostly hit in the water near the shore of ponds, lakes, paddy fields or small river ditches, and consist of an upper hole, a lower hole and a nest. ”

The upper hole is generally about 10 cm below the water surface, and the lower hole is about 30~40 cm below the water surface. The diameter of the hole varies according to the size of the eel, the small finger is thick, and the large one can reach 6~7 cm. The nest is between the upper hole and the lower hole, it is round, about 10~15 cm in diameter, and it is the place where the yellow eel turns, lays eggs, and incubates eggs.

The eel cave in the soft soil is mostly close to the water line, even if it is submerged under the water, it is temporary, and the eel will constantly change the position of the hole, so that the hole is often at the level of the water line, so as to keep the hole moist and avoid being flooded by water.

Eel holes can be identified by the rounded, smooth opening of the hole, located in an area of 8 cm above the waterline. After discovering the cave, look for signs of creeping from the entrance to the waterline. Sometimes, the eel's burrow is also below the waterline, mostly because the water rises and there is no time to adjust the entrance to the cave.

"As for the eel cave in the river, it's a little harder to judge. The eel burrows in rivers have no obvious features and are generally below the waterline. On some stone shores, those stone crevices are also where yellow eels like to hide, and there are often several yellow eels hidden in a stone cave. Chu Jiaqiang said to them.
