After speaking, Tu Yisho changed the water and went out with a fishing rod.

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

Tu Yisho smiled: "Yes, guess what fish?"

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

Tu Yisho straightened his waist proudly: "Carp, hum, this thing is well done, just make a lot of ingredients, how can I show my ability?"

There was a small plank bed by the pond, painted on it, and when it was turned over and thrown into the water, it was a boat, a very simple sampan.

Tu Yisho got into the boat and looked at Ao Muyang, Ao Muyang asked, "Is the water in your pond dirty?"

The old man shook his head: "How can there be pollution? It's very clean, the garbage in the village is not dumped here, at most some old ladies come to wash clothes." ”

Ao Muyang said: "That's good, if I go down, I will go directly into the water, and you can go fishing." ”

He didn't know what fish Tu Yisho was going to catch, but the old man was not a master of fishing, and after throwing the fishing rod down, he brought it up several times, but he didn't catch any fish.

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

Ao Muyang looked at his phone and said, "I'm not in a hurry, you fish slowly." ”

Tu Yi's shovel is slow, and the evening is full of red clouds, and the night is coming.

Ao Muyang asked, "Old man, are you going to go fishing at night?"

The old man said stupidly: "Today's perch is particularly cunning, and it is usually very easy to catch." ”

Hearing his words, Ao Muyang asked rhetorically: "Perch, do you have river bass or largemouth bass here?"

There are many species of fish in Chinese that can be called sea bass, and the four most common ones are: sea bass, scientific name Dongying true sea bass, distributed in the offshore and estuarine seawater and fresh water confluence.

There are also three types of freshwater perch, namely Matsue perch, which is the most famous, but it was only produced in the magic capital before, and some even said that it was only produced under the Matsue Hideno Bridge.

Then there is the largemouth bass and the perch, the largemouth bass, also known as the California bass, a new species introduced from the United States. River perch, also known as red perch and Wudaohei, is produced in northern Xinjiang.

These perch are not visible in the red ocean freshwater rivers and lakes, if there are introduced species, it should be largemouth bass and perch, Songjiang perch is too rare, after the 70s of the 20th century, due to the river change lanes, sluice blockage and other reasons, this fish is almost extinct.

Later, around 2,000 years later, the Modu Fisheries Research Department sent seven teams to the coastal areas of the country to search, and finally found traces of this wild fish at the mouth of the Yalu River, and then carefully brought it back for artificial breeding.

Even the captive-cultured Songjiang perch is rare, and it is unlikely to be found in a pond in the mainland, because it is a coastal migratory fish, and the juveniles travel the river from late April to early June, with the peak in May, and the adults fall to the sea from November to February.

Every spring, juveniles swim from the Yangtze River estuary to the inland river to grow and fatten, and in autumn, after sexual maturity, they swim to the junction of the Yangtze River estuary and freshwater to spawn and reproduce offspring, and the cycle repeats.

But the old man gave him a piece of news that made him stunned: "No, it's a four-gill perch!"

Four-gill perch, this is another name for Songjiang perch, because in "Continuation of the Rhyme", "the perch in the world are all two-gills, only the perch of Songjiang is four-gill".

Ao Muyang said in surprise: "This is impossible, how can you feed fourgill perch in this pond? How can they breed? Can there be wild fourgill perch here?"

The old man smiled: "It's not wild, someone sent it to me, I worked in the guest house in Hongyang for many years, and then this is not a good reputation, the leader asked me to resign myself, I wrote in the resignation letter at that time" Thoughts of the perch', the guest house happened to get a few live fourgill perch at that time, and then the leader gave it to me, I went home and threw them in this lake. ”

The idiom of the thought of the perch is about an official named Zhang Han in Luoyang - this Zhang Han is a famous man in the Jin Dynasty, not the one who shouts on the screen now 'It's not my fault that he looks handsome', Zhang Han is politically unwilling, and he saw that the Central Plains was about to be in chaos, so he pretended to see the autumn wind and miss the Ulva and perch in his hometown, and resigned and returned.

Listening to his words, Ao Muyang felt that something was wrong: "How many perch? How many have you usually fished? Is there anything left here?"

Fourgill perch can survive in freshwater, but they can't reproduce offspring.

Tu Yisho's words shocked him again: "I put a few in it, but then I found out that they have multiplied, really, I usually catch one or two occasionally, and I must have caught dozens of them before and after." ”

"It's impossible. Ao Muyang shook his head again and again.

Tu Yisho smiled and said: "I also think it's impossible, but then I found out that this pond is a divine 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 his surprise this year was not as good as this afternoon, so he was surprised again and asked, "Is this a double-decker lake?"

Tu Yisho shook his head: "What double-decker lake? Anyway, this pond is so godly, and I only found out after raising this perch." ”

Ao Muyang explained to him: "The double-decker lake is a wonder of the world, there is a Newark Lake in Barrow Point in northern Alaska, where the lake has two layers of water, maintaining a clear dividing line, the upper layer is freshwater, where freshwater fish live, and the lower layer is slightly bitter saltwater, with marine animals and plants. ”

Tu Yisho said: "Oh, then this is, but the pond is too small, not a lake, and there are no marine animals and plants, just the four-gill perch is in it, I also happened to find it, except for my village, no one has discovered this secret." ”

This is indeed a secret, Ao Muyang took off his clothes and jumped into the pond, anyway, Tu Yisho has already said that the water quality of this pond is very clean.

Jumping into the water, he looked down.

Don't look at this pond is not big, in fact, it is quite deep, the center of the pond has to be about ten meters deep, which is deeper than many wells in the countryside.

He looked into the water and found that the water quality was different, the upper water was clearer, the lower water was bluer, and it had a special place compared to other ponds, that is, there were no aquatic plants at the bottom of the pond, but there were many aquatic plants growing along the four sides of the pond.

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

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