Badfish, return!

Cover Journalist Du Jiangqian Du Zhuo Bin Li Jiayu Wu Xuemei Xiaoyang Liangjiaqi Photography Report

This summer, a Chinese cricket is about to usher in the mountains of the mayor of Ning County, Yibin, Sichuan Province. When it was a "water flower" of 1 centimeter, it was brought back to Yibin from Jingzhou, Hubei. It was an autumn. The old man wrapped the small fish bag with a cotton coat and took the boat in his arms for more than 10 days to return home.

Today, at the breeding base of the Yibin Rare Aquatic Animal Research Institute (hereinafter referred to as Yibin), the earliest batch of Chinese crickets had only 3 tails.

It has grown more than two meters of "big fish" and weighs nearly 200 pounds. It is not good -tempered, and it will bring heavy ripples when accelerating the tour, and the momentum of the ancient giant fish is not angry. Therefore, as the current person in charge of Yibin, Zhou Liang specifically set up a pond for it. As for the Yangtze River that arrived here in the same year and it was born in the same year, Zhou Liang could only cover his mouth and laughed. "I can't recognize the first batch.

On August 18th, according to the information released by the Sichuan Provincial Committee of the Communist Party of China, "China Ten Years · Sichuan" theme press conference, in the "Qianhe Province" Sichuan, the province's water environment and quality have been greatly improved in recent years. The best level, the dry water quality of the Yangtze River and the Yellow River stabilizes the II class.

It has become the normal proliferation release activity

The "big fish" in the base did not know these changes.

They grew in the ponds of Yibin. They did not know that their ancestors traveled to the Yangtze River, and they had not experienced the big of the Yangtze River. As for this earliest private Yangtze River rare fish research institution in the country, the increasing breeding pressure, expectations for new policies, and the hope of the Yangtze River are tightly woven year by year.

On the other hand, the academic circles have been working hard to promote the artificial breeding and utilization of the Yangtze River over the years. It seems that on the one hand, the Yangtze River in the wild has not found out of the wild, and on the other hand, it is the maturity of the corresponding artificial breeding technology. The door between the two is waiting for the turbulent river water to break through it.

There is no doubt that there are big fish in the Great River, and the catfish from ancient times are in the new story that belongs to them.

Yangtze River, still hopeful

On August 10, more than 2,000 Yangtze River was put back to the Yangtze River in Jiang'an County, Yibin, Sichuan. These fish -born fish fry had grown to the size of the palm of the adults. When returning, Zhou Liang replaced the more formal coat. He said to the lively Yangtze River, "Go to the Yangtze River to live a happy life."

On August 10, the 2000 Yangtze River Put returned to the scene

As the director of Yiya, this summer, he felt very busy.

On June 6, the culinary "Fish Day" Sichuan proliferation and release activity of the National "Fish Day" was held in Yibin. As a long -term partner, this year Yibin provided more than 600 Yangtze River crickets, including the cultivation of "big fish" weighing more than 10 kilograms and more than 1 meter long, and fishing for about 6 cm long. In late June, Zhou Liang took another fish fry to Chongqing to participate in the release. This year, the Chongqing Fifth Court tried the country's first illegal fishing and consumption of the heavy ecological lawsuit of the Yangtze River, and the defendant voluntarily paid the ecological restoration. After returning from Chongqing, Zhou Liangma rushed to Jiang'an County, Yibin, signed a proliferative release cooperation agreement with the local area, and then hurried back to the breeding base in Changning, Yibin. I am afraid of the hypoxia and illness of the fry.

The river did not stop. Zhou Liang, 50, has been around the fish.

Zhou Liang's daily work

When he first graduated, he was "dragged" by his father Zhou Shiwu to the fish pond. Thirty years ago, the wishes of the father and son could still realize the artificial reproduction of the Chinese and Yangtze River in Yibin. After his father's death, Zhou Liang took over the Yibin Institute. As a manual breeding institution of the Yangtze River in the Agricultural and Rural Ministry, his biggest wish is the wild population that can rebuild the Yangtze River.

Zhou Liang's father Zhou Shiwu

Therefore, on July 21, when the World Nature Conservation Alliance (IUCN) announced that when the white lame is extinct and the Yangtze River's 鲟 因 因, although he had long been mentally prepared, he was still a little bit embarrassed, like a high -speed machine stop. That day, he went down to Nanxi with his intuition.

In 2003, humans were witnessed and touched Bai Yan there for the last time. In the rescue team, this is not the first time that Zhou Liang has seen this legendary animal. In the early 1990s, their father and son had rescued another white magpie. It was a 3 -meter -long "Jiangzhong overlord", the long kiss, which is exactly the same as the "Similar and long nose, no scales and armor" in the "Shan Hai Jing".

"It's particularly beautiful." Zhou Liang remembered that the white pupae that had died due to the serious injury and the healing was not effective. This white cricket was not particularly injured and had thick fish eggs in his belly.

"But maybe it is the last white puppet in the Yangtze River." Zhou Liang felt that in Yibin, the vibration and impact surface of this sad news were wider and deeper. For this "first city of the Yangtze River", rivers and cities have long been integrated, and everyone can tell stories related to fish -related stories.

In the summer season, Zhou Liang inspected the growth of the Yangtze River

Zhou Tao, the captain of the Changjiang patrol team in Jiang'an County, is the earliest citizen of spontaneous organizing fish protection operations. He parked the car in the recent highway service area, turned out the full text of the news and read it. Tian Fuyou, a retired reporter of the West China Metropolis Daily, revealed the newspaper's rescue report by him 19 years ago. In a sense, he did not recognize this assertion. He firmly believed that the Yangtze River, which was thousands of kilometers, could not be touched by the current detection technology, "at least the Yangtze River, there is hope." This attitude.

In the catfish family, this relatively small catfish is a unique species in my country, and it is only found in the middle and upper and upstream watersions of the Yangtze River. Although natural reproduction has not been monitored for 20 years, domestic experts have done imitation ecological simulation tests. Under the conditions of the conditions, the Yangtze River can breed naturally.

"Although the natural reproduction of the Yangtze River has stopped for many years, the functionality of habitats such as bait and wintering on the upper reaches of its upstream is still good." Du Hao, a researcher at the Yangtze River Institute of Aquatic Products of the Chinese Academy of Fisheries Science There are natural reproduction activities, but with the continuous advancement of large -scale proliferation and release, the continuous implementation of the relevant Yangtze River protection ecological restoration and protection measures, "the natural population reconstruction of the ancient and endangered species of the Yangtze River can be realized."

Since 2007, Yibin has already released a total of 13.32 million fish.

Ancient fish, stupid fish

In the river in Nanxi, Zhou Liang called Du Hao. In 2006, the two met because of their common ambitions for the protection of the Yangtze River catfish in 2006. Protecting technology research, Yibin cooperates with its relevant experiments and is mainly responsible for breeding engineering technology.

They have been optimistic about the field population that restore the Yangtze River.

"What is the previous survival rate, how much is it now?" On the other side of the phone, Du Hao was a little excited. Although this young expert who has been around the Yangtze River for 20 years, this is only 40 years old. A little change. "When the old man was at it, he could be happy to live. Now, the more than 80,000 fry fry you hatched this year will die less than 100 tails."

On the other side of the phone, Zhou Liang suddenly heard his father's name. Among the tens of millions of lines of the Yangtze River protection, the one he felt he dragged was named inheritance.

"Yibin has a pair of surnames and surnames that has made outstanding contributions to the protection of the Yangtze River." In 2021, in the selection of the top ten green pioneers in Sichuan Province, experts have commented on this.

Judging from several main points, Yibin's first successfully achieved the artificial reproduction of the Yangtze River in 1998. By 2000, the wild Yangtze River was scarce. In 2007, the Yibin Institute successfully achieved the success of the Yangtze River. In 2010, the Yangtze River was upgraded to the "extremely crisis" by the World Nature Conservation Alliance. In 2015, there were only 21 tails of the Yangtze River in the Yangtze River, which were known at the time, and 18 of them came from Yibin. In 2018, the Yibin Institute and the Yangtze River Institute jointly broke through the breeding of the three generations of seedlings in the Yangtze River.

Yangtze River Seedlings

"Most of the Yangtze River crickets that can be found in the Yangtze River now come from the seedlings of Yibin." As a long -term partner of Yibin, the view of Zhou Bo, deputy director of the Institute of Aquatic Research Institute of Sichuan Academy of Agricultural Sciences, is the consensus of the current academic community. The flagship population represented by the Yangtze River 鲟 and Chinese 表 is an important indicator of the ecological restoration of the Yangtze River, and it is also the wish of their generation of researchers.

"Ancient fish is a bit of stupid fish." For 30 years with the fish, Zhou Liang felt that the catfish was stupid. For example, what you eat at birth, it is determined that it will not change, "the brain is not allowed to turn." Therefore, when the first batch of catfish only eat water or earthworms, everyone can only climb into the mountains every day, dig the earthworms in the soft soil, and dig a whole day. Each year, Zhonghua Lang and the Yangtze River are laying eggs. He stayed all night. Under the mountains and forests, he listened to the sound of water. He always felt that after having emotional cognition with those fish, he wanted to go for them. What do you do.

"Go back to the Yangtze River early and go back to my hometown to enjoy blessings." For a long time, Zhou Liang often said to the fish.

Judging from the data collected by Du Hao, in the 10 years from 2007 to 2017, the flow scale of the Yangtze River was less than 50,000. With the development of the Yangtze River, from 2018 to the present, the upper reaches of the Yangtze River guided by the Ministry of Agriculture and Rural Ministry The municipalities along the river have carried out a large -scale growth and release activity of the Yangtze River in the Yangtze River. "In the past 4 years, the release of the Yangtze River in the flowing of the Yangtze River is incomplete statistics. It has about 600 tails of adenic development and nearly 340,000 juveniles."

Fortunately, before the Yangtze River walked to extremely dangerous, his father Zhou Shiwu left the fish species with intuition. It was an old man who was a little "axis". The earliest people began to do the ornamental fish business because of their hobbies. During the period, they felt that they should leave the Yangtze River and Chinese crickets for their future generations, and then pierced the artificial reproduction of two catfish. In 2016, the old man died, and Zhou Liang had always kept all the letters written by his father to him. In the powerful and bright handwriting, the old man told his son, "As a friend with nature and science, be a sweet and beautiful dream. "

"If the old man still cares about before walking, it must be that the wild population of catfish has recovered." Around 2015, the Yangtze River was found in Yibin. Zhou Liang rushed to the scene. Grow up.

In terms of overall data, before 2018, the total number of arrests and misunderstandings in the Yangtze River in the Yangtze River was 591. In 2021, the investigation team launched a survey and monitoring of the Yangtze River in Baixi, Yangtze River, Hejiang, and Luzhou River in Jinsha River. The number before the arrest. Taking Yibao as an example, since 2007, a total of 13.32 million fishes have been distributed, which has effectively promoted the diversity of aquatic biodiversity in the Yangtze River and promoted the continuous improvement of the ecological environment of the Yangtze River waters.

In Du Hao's view, the monitoring in recent years has also proved that the proliferation and release after the ban on fishing in the Yangtze River has a significant role in promoting the breeding population in the water. Growth is good.

This means that "stupid" fish is growing up in the Yangtze River.

Yangtze New Story

But returning to the Yangtze River is only the first step in the reconstruction of the Yangtze River's Langye.

Today, there are two breeding bases in Yibin, which are distributed throughout Changning, and the third breeding base will be used within this year. From the perspective of the academic community, the "Yangtze River" of the breeding base is not a real "Yangtze River" 鲟, and one step away is to achieve wild breeding and reconstruction in the Yangtze River.

This includes two aspects of conditions, a certain size of the age, and the appropriate spawning place.

"This is actually a very difficult condition." Du Hao's team has experimented indoors. Under the conditions of the conditions, the Yangtze River can spontaneously meet the spawning reproduction in an artificially simulated spawning environment. However, the Yangtze River Basin is the most densely economic activity area. Some human activities will affect the development, metabolism, and laying of fish. Therefore, in order to realize the reconstruction of the wild population in the Yangtze River, the ecological restoration of the Yangtze River should also include the restoration of the natural spawning field environment of the Yangtze River.

At the same time, the base of the Yangtze River in the Yangtze River is still too small, and it is difficult to meet mature male and female fish.

In 2018, Yibin began to participate in the Yangtze River rescue plan of the Ministry of Agriculture and Rural Ministry. For two consecutive years, the proliferation and release of 180,000 Yangtze River seedlings. "Our subsequent feedback is probably estimated to have an accurate survival rate. 1%to 1.6%. In this kind of base, there are fewer male and female fish growing up, and they must be encountered. This is like a pair of young men and women, one in Shanghai and one in Sichuan. Object. "

In this regard, experts have made an estimate that the annual flow volume of the Yangtze River seedlings is 30-5 million, and after 5-10 years in a row, it has the basis of the number of wild reproduction.

On the other hand, in the major Yangtze River breeding bases in the country, the annual egg yield can be guaranteed to be more than one million, huge breeding pressure, limited special funding support, how to explore the use of protection strategies to allow Yangtze River to enter artificial artificial artificial artificial manual The key list of breeding has been promoted in the industry.

In April 2021, at the Aquatic Wildlife Protection Branch of the China Wildlife Protection Association, experts held a special demonstration meeting to discuss artificially breeding the second generation and later generations of the second generation of Chinese crickets, the Yangtze River Dispaye "Aquatic Wildlife List".

At the meeting, Du Hao took out the way to carry out breeding and utilization on the premise of ensuring the repair of field resources and the proposal of "using protection". It is recommended to mention that through standardized and rational use, the pressures, venues and other pressures faced by artificial insurance can be alleviated to use the funding problems of promoting protection, solving the funding of artificial preservation, proliferation and release, and scientific research, and then promote the protection of Chinese and Yangtze River. develop.

As far as Yu Zhou Liang is concerned, he has been preparing for artificial breeding in the Yangtze River. In the breeding base of Yiyi, there is a special pond, which has been accumulated in the past 30 years and chosen from hundreds of thousands of breeding fry per batch. Chan Ruojin chrysanthemum.

Zhou Liang longed for his father Zhou Shiwu told him that he saw a fisherman pushing a giant "salad fish" on the streets on the street. To leave this kind of fish. "

For more ordinary people, what is more important than hope is to become a habit of protecting behavior.

Just this summer, Yibin Jiang'an occasionally encountered the Yangtze River. They called the local fishery administration department and let them go together.

This is not unusual in the local area.

"More and more people are involved in protection." Zhou Liang felt that he was in a reasonable hope. He believes that in the ten years of banning fishing in the Yangtze River, it is said that the scene of catfish jumping out of the river will reproduce, which is a new story of Yangtze River in this era.
