After saying that, Tu Yishao changed into water and took the fishing rod out of the door.

Ao Muyang looked at the pond next to him and asked, "Old man, are you planning to catch fish and make it?"

Tu Yishang smiled and said, "Yes, guess what fish are you?"

Ao Muyang shook his head: "I can't guess this, but making carp is a dish that tests the chef. Are you going to show off your skills in this regard?"

Tu Yizhang proudly straightened his waist: "Carp? Humph, this thing is well made, just put in the big stuff as much as possible. How can I show my skills?"

There is a small wooden bed next to the pond, painted on it, and after turning it over, it will be a boat, a very simple sampan boat.

Tu Yishao got on the boat and looked at Ao Muyang. Ao Muyang asked, "Is the water in your pond dirty? Is there any pollution?"

The old man shook his head: "Where is pollution? It's very clean. The village garbage is not dumped here. At most, some old ladies come to wash their clothes."

Ao Muyang said: "That's good. If I go down, I will go into the water directly. You go fishing."

He didn't know what fish to catch in Tu Yishao, but the old man was not a fishing expert. He threw the fishing rod several times and picked it up, but he didn't catch any fish.

Time passed, Tu Yishao was a little embarrassed, so he turned around and said, "This fish is not ordinary, we can eat it here, boss, you have to be patient and wait."

Ao Muyang looked at his cell phone and said, "I'm not in a hurry, you can catch it slowly."

The slow tumbler was slow, and the heat came out. In the evening, the red clouds filled the sky, and the night was about to fall.

Ao Muyang asked, "Old man, are you going to have a night fishing?"

The old man said angrily: "Today, this bass is particularly cunning and is easy to catch."

After hearing his words, Ao Muyang asked back: "Perces? Do you have river perch or largemouth black bass here?"

There are many species of fish in Chinese that can be called perch, the four most common species are: sea bass, scientifically known as the Japanese real perch, distributed near the sea and at the intersection of freshwater in the estuary.

There are three other types of freshwater perch, namely Songjiang perch, which is the most famous, but was only produced in the Magic City before, and some even said that it was produced exclusively under the Songjiang Hideo Bridge.

Then there are largemouth black bass and river perch. Largemouth black bass is also called California bass, a new variety introduced from the United States. River perch is also called red bass, which is five black bass and is produced in the northern Xinjiang region.

These perch are not visible in the red ocean freshwater rivers and lakes. If there are introduced varieties, they should be largemouth black bass and river perch. Songjiang perch is too rare. After the 1970s, this fish was almost extinct due to river lane change and sluice blocking.

Later, about two thousand years ago, the Aquatic Products Research Department of the Magic City sent 7 teams to the coastal areas across the country to search. Finally, the traces of this wild fish were found at the mouth of the Yalu River, and then carefully brought them back for artificial breeding.

Even artificially farmed Songjiang perch is rare. It cannot appear in a pond in the mainland because this fish is a coastal migratory fish. The young fish go up the river from late April to early June, with the most prosperous in May, and the adult fish descended to the sea from November to February of the following year.

Every spring, young fish swim from the estuary of the Yangtze River to the growth and fattening of the inland rivers; in autumn, after sexual maturity, they swim to the junction of seawater and freshwater in the Yangtze River estuary to lay eggs, reproduce offspring, and repeat.

But the old man gave him a message that made him stunned: "Not all, it's four-gilled perch!"

Four-gilled perch, this is the nickname of Songjiang perch, because in "Xuyunfu", "the perch in the world has two gills, but only Songjiang perch has four gills".

Ao Muyang said in surprise: "This is impossible. How can you feed four-gilled perch in your pond? How do they breed? Can there be wild four-gilled perch here?"

The old man smiled and said, "It's not wild, it's because someone sent it to me. I worked in Hongyang's guesthouse for many years. Later, this reputation was not bad, so the superior leader asked me to resign myself. I wrote 'Thoughts of Watermelon and Perch' in the resignation letter. The guesthouse happened to get a few live four-gill perch, and then the leader gave it to me. After I got home, I threw them in the lake."

The idiom "Sutra" of Water Vessel and Perch" refers to an official named Zhang Han in Luoyang - a famous scholar in the Jin Dynasty, not the one who shouted "It's not my fault to be handsome" on the screen. Zhang Han was unsuccessful in politics, and saw that the Central Plains were about to be in chaos, so he missed the water Vessel and perch sashimi in his hometown when he saw the autumn wind rising, and resigned and returned.

Listening to his words, Ao Muyang felt something was wrong: "How many perch? How many have you caught? Can there be any remaining one here?"

The four-gilled perch can survive in fresh water, but it can't reproduce offspring.

Tu Yishao shocked him again: "I put a few of them in, but later I found that they were breeding. Really, I occasionally catch one or two, and I have caught dozens of them."

"This is absolutely impossible." Ao Muyang shook his head repeatedly.

Tu Yishang smiled and said, "I don't think it's possible, but later I discovered that this pond is a magical pond. If you can go down, you will know that its upper and lower layers of water are fresh water and sea water!"

Ao Muyang felt that the surprise he had this year was not as good as this afternoon. He was surprised again and asked back: "Is this a double-layer lake?"

Tu Yizhang shook his head: "What double-layer lake? Anyway, this pond is so magical. I only discovered it after raising this bass."

Ao Muyang explained to him: "The double-layer lake is a wonder of the world. There is Newark Lake in Barrow Cape in northern Alaska, USA. The lake water is divided into two layers, maintaining a clear dividing line. The upper layer is fresh water, living with freshwater fish; the lower layer is slightly bitter salt water, with sea animals and plants."

Tu Yishang said, "Oh, that's it, but the pond is too small, not a lake, and there are no sea animals and plants. I happened to find the four-gilled perch inside. No one except my village discovered this secret."

This is indeed a secret. Ao Muyang took off his clothes and jumped into the pond. Tu Yishao had already said that the water quality in this pond was very clean.

Jumping into the water, he looked down.

Although the pond is not big, it is actually quite deep. The center of the pond must be about ten meters deep, which is deeper than many wells in rural areas.

When he looked into the water, he found that the water quality was different. The upper water was clearer and the lower water was bluer. Compared with other ponds, it had a special place, that is, there was no water grass at the bottom of the pond, but there were a lot of water grass growing around the pond.

Not only is there no aquatic plants, but to be precise, there is no life in the lower layer of this pond. There may be some plankton that cannot be seen by this eye, but the level that human eyes can see is nothing.

There are many fish in the upper waters, but there are very few species, such as crucian carp, grass carp, loach, and carp. There is also a fish with a special appearance, which is the key point.
