"The Yangtze River has been the mother river of the Chinese nation since ancient times. This third largest river in the world has a total length of 4,504 kilometers, a drainage area of ​​1 million square kilometers, and a total water resource of 961.6 billion cubic meters, which is 20 times that of the Yellow River. It has rich aquatic resources, liberating In the past, it could provide about 500,000 tons of catch every year. In recent years, due to excessive hunting by humans, the Yangtze River’s aquatic resources have been nearly exhausted, and the annual harvest is less than 80,000 tons. The world-famous Yangtze River shad, saury, Chinese sturgeon, etc. are on the verge of extinction. They are the goddess of the Yangtze River. The so-called Baiji dolphin has been declared functionally extinct. The four most common domestic fishes have also dropped from more than 30 billion fish per year to less than 100 million at present. In order to protect water resources and the reproduction of aquatic organisms, 3-3 fish per year are required. June is the fishing ban season in the Yangtze River, and the specific time is determined by the governments of each river basin..."

On the way to Huayin County, Nangong Huang took an Ipad and sat in the back seat to check information on the Internet.

In fact, this information is meaningless. Su Ming and the others are not from the Yangtze River Bureau. This trip to Huayin County is mainly for tourism and to see if there are any fisheries worth buying. The current situation of the Yangtze River water resources is not something Su Ming should be concerned about. Even if he wants to, he is unable to do so now.

However, since Nangong Huang showed that he was willing to work hard and did his homework beforehand, Su Ming would certainly support him.

Also coming together is Su Meng, the number one personal bodyguard, and Hai Dongqing in the sky. Nangong took almost a month's leave before going to Xiangjiang. After coming back, he worked overtime all day to make up for the work and couldn't leave at all.

I originally wanted to call Liang Shi here, but he is the real aquatic products expert.

Unfortunately, just one day before departure, Liang Shi received bad news: Professor Chu called to say that the two baiji dolphins raised in the provincial conservation center had died.

Yes, it is the Baiji dolphin known as the goddess of the Yangtze River that Nangong Huang mentioned just now.

Su Ming also later learned that the Baiji dolphin is actually even rarer than the finless porpoise. In the wild, both species have basically become extinct. However, under the protection of artificial breeding, there are still a dozen or twenty finless porpoises, but the Baiji dolphin is rarer than the finless porpoise. For dolphins, there are only two single seedlings from the Provincial Fisheries Protection Center in the country.

In other parts of the country, there are a few so-called "Baiji Dolphin Centers", but they all sell dog meat with sheep's heads, and the only animals raised inside are finless porpoises.

After receiving the call, Liang Shi cried and asked for leave to return to the provincial capital. He attended the Baiji Dolphin's farewell ceremony and performed an autopsy to make a specimen... It's not that Liang Shi is a crybaby, she just has too deep feelings. He has been in college for four years. During the first year and a half of my postgraduate studies, except for classes, I spent almost all the remaining time at the conservation center with these two finless porpoises.

Su Ming criticized Liang Shi very seriously, no wonder he couldn't find a girlfriend and deserved to be single all his life!

These two Baiji dolphins died in a relatively peaceful manner, but Professor Chu from the Provincial Academy of Agricultural Sciences and others were dumbfounded. Now they were completely dead. The death of the last two Baiji dolphins could almost declare the Baiji dolphins to be dead. This creature becomes extinct.

When they were alive, they had some hope. Let them make a few babies, or use artificial insemination technology. Now that they are dead, it is like a widow giving up her son, and there is no hope at all.

In the eyes of ordinary people like Su Ming, the extinction of the Baiji dolphin has no impact. It is nothing more than a sigh after dinner. But in the eyes of professionals like Professor Liang Shichu, this was a catastrophic disaster. Even the retired principal Song went to the provincial capital with Liang Shi to take a last look at the Baiji dolphin.

Giant panda, alligator, Baiji dolphin, several of the most representative Chinese creatures, the Baiji dolphin is just gone. Alligators and giant pandas are also living on the verge of extinction. Su Ming estimates that maybe in one or two hundred years, future generations will be extremely excited when they see a big bad wolf: Mom, look, the big bad wolf is a national treasure... …

"Brother-in-law, let me tell you, what a waste of protection! Let those fishermen overfish and until they are all extinct, let those bastard fishermen reap the consequences!" Nangong Huang said angrily from the back row.

"The fisheries in the Yangtze River have dried up, and the fishermen cannot be blamed mainly." Su Ming shook his head. Yes, the fishermen use high technology and use small mesh nets, but if you look at the catch, you can see that fifty years ago, it was 500,000 tons, but now it is less than 80,000 tons, and the fish caught are actually less.

Among the four major factors that cause biological extinction, including overfishing, water conservancy project construction, water environment pollution and sand dredging, overfishing has the smallest impact. The worst thing is that the construction of hydropower stations and dams directly cuts off the river flow, cuts off the migration routes of fish, and destroys fish habitats.

There are also sewage discharges. There are countless heavily polluting enterprises on both sides of the Yangtze River. Liang Shi and his colleagues have investigated and found that 30,000 tons of sewage are discharged into the Yangtze River every second.

Liang Shi half-jokingly said that in the past few decades, sewage pollution has caused far more damage to China than the Japanese invasion of China, and many of the losses are permanent. Some species disappear unknowingly. It will not have as drastic social repercussions as the tainted milk powder incident, but species resources are gone when they disappear. This is a huge harm to species genetic resources and biodiversity. When most of the fish species in the Yangtze River are gone, the Yangtze River will die.

"Does the government not care?" Nangong Huang asked.

Su Ming glanced at him and said, "Your brother-in-law, I'm not the government, so it's useless for you to ask me. I didn't realize that you, a guy who can't even recite the English alphabet, are actually quite concerned about the country and the people."

Nangong Huang said something that made Su Ming very upset: "Every man has a share of responsibility for the rise and fall of a country!"

Different positions lead to different ways of settling accounts. Liang Shi only calculated environmental accounts, but it must be said that pollution also brought economic prosperity, and the trade-offs cannot be explained in a few words.

Su Ming was too lazy to think about such a lofty question. It was more important to manage his own piece of land.

Huayin County is just over three kilometers away from Yangchuan City. You don't even need to take the national highway. After leaving the city and driving along the county road for a while, you will arrive at a small county town by the river.

The county town is not big. Standing at a slightly higher place, you can have a panoramic view of the entire county town. It is just a large fishing village with a slightly higher degree of modernization.

It has been the third day since the Yangtze River opened for fishing. After entering the city, there is no sign of water depletion. On the contrary, it is bustling and prosperous.

There are rows of large water tanks at the door of every household, which are densely packed with newly caught river fish; various fishing houses and small restaurants with special features are everywhere.

There are not only simple fishermen with dark skin, but also more tourists coming from all directions in the small county town at this time.

Every year when the fishing season starts, Huayin County will attract many tourists to taste new fish. Huayin County has also developed some water tourism projects, such as cruises and fishing. Tourism has almost become the second industry of Huayin County.

Su Ming came here this time with the idea of ​​looking for economic fish and bringing them back to the reservoir for breeding. He was not in a hurry to rush to the venue of the "Exchange Meeting". He parked his car in the parking lot outside the county town, walked and stopped along the way, asked the price of each fish stall, and inquired about the market.

I didn't see any special fish, mainly the four big fish, there were also many small silver fish, and I saw two eels.

Even Su Ming could tell that the eel was most likely artificially bred. These days, it is hard to find large-scale wild eels in the Yangtze River.

Crabs are good, but the problem is that this place is not far from Poyang Lake. No matter how much they are cultivated, it is difficult to catch up with the reputation of Poyang Lake hairy crabs that have accumulated over the past decade. Moreover, these aggressive guys eat small fish fry. Putting them in the reservoir is not worth the loss. If they are not handled properly, they may become a disaster.

"Brother-in-law, look..." Nangong Huang suddenly pulled Su Ming's sleeve and pointed at a remote fish shop.

The shop was not big, but there were many tourists around the water tank at the door. They curiously stretched their heads to look and pointed at the fish tank.

Squeezing into the crowd, I saw three large water tanks at the door, with hundreds of fat fish about the length of a palm in the water tank.

These fish are round and plump, like a little fat boy, very cute, with blue-gray stripes on the back, white belly, and a straight little thorn on the back, shaking their heads and swimming in the water.

At first glance, it looks like a mutant frog without legs.

Su Ming was happy, no wonder so many people were watching, these fat fish in front of him were the legendary "pufferfish".

Pufferfish are brackish water animals that live in shallow seas. Every year when the fish are in season, a large number of pufferfish will return to the Yangtze River system, and the yield is rich. If they are along the coast, they can be caught almost all year round. Pufferfish muscles are as white as frost, the meat is plump, tender and delicious, and contains extremely high protein. The ancients even said that "if you don't eat pufferfish, you don't know the taste of fish."

The pufferfish in front of him has a green back, strictly speaking, it is called "dark-striped oriental pufferfish".

Nangong Huang introduced with a smile on his face that puffer fish has another nickname. Ancient literati called it "Xi Shi's milk", which means that its meat is as white as milk, plump and delicious, and melts in the mouth, just like the milk of the beautiful Xi Shi.

"Nonsense, ancient literati were all very reserved. Xi Shi's milk is Xi Shi's milk, but it definitely does not refer to Xi Shi's milk." Su Ming said.

"What is that?" Nangong Huang was still a half-grown child after all, and could not immediately understand the mess in Su Ming's mind.

"Uh... forget it, it's nothing." Su Ming closed his mouth. It's okay to discuss this topic with Nangong, but don't teach the child bad things.

In ancient China, there was a saying of "risking life to eat puffer fish". Puffer fish contains a highly toxic substance. From ancient times to the present, many people have been poisoned to death by greedy puffer fish. Even so, there are still generations of gourmets who go to gamble their lives to eat puffer fish, which shows that its taste is indeed tempting.

Plus, pufferfish looks cute, so there are a lot of people watching, but few people pay to buy it. Pufferfish is not something that ordinary housewives can make. Even the hotel chefs dare not try it easily. If they are not careful, they will cause death.

The owner of the fish shop is a dark-skinned middle-aged man. He squatted behind the water tank and shouted anxiously: "Boss, buy a few. This thing is not only delicious, but also fun. You dare not eat it when you buy it home, but you can also keep it as a pet fish!"

Someone pointed at the pufferfish and laughed: "How to play this?"

Yesterday was a good day, 520, and Huo Jianhua suddenly got together with Ruby Lin.

When I got the news, I immediately searched all the toilets in the city, hoping to catch a crying wild Hu Ge~~
