Cover Journalist Su Dingwei intern Zheng Na

Post -90s Fish Ecology and Resource Protection Doctor, Associate Professor of the School of Environmental Sciences and Engineering of Xihua Normal University, is Zhang Fubin, a representative of the fourth -generation fish experts in the school. In the past half a century, Zhang Fubin and his predecessors have carried out the survey and research of fish resource in Jialing River.

Zhang Fubin finds information

In the first half of 2022, fish monitoring of the river in the south of the Jialing River just ended, 45. In the past half a century, Jialing River fish has dropped sharply. The Jialing River is a mirror in the Yangtze River, and the responsibility for fishing is great!

The four generations of scholars continue to monitor the Jialing River

Dr. ""'s office is like a big fish hall

"Zhuangzi · Xiaoyaoyou": "There is fish in the north, and its name is 鲲. I do n’t know how many thousand miles are." Zhang Fubin, WeChat name "鲲", mainly attacked fish research. The gentleness and the speed of speech are slow. The post -90s doctoral exchanges with the fish for 13 years and are one of the fourth -generation research fish representatives of the Xihua Normal University.

Zhang Fubin in the laboratory

The "National Freshwater Fisheries Engineering Research Center (Wuhan) Southwest Branch", a large office, fish tanks everywhere, fish specimens in plastic barrels. When I first entered the office, I thought I walked into the fish hall. Zhang Fubin's station is in the corner, crowded and aggressive. The bookcase is full of fish books.

In 1976, Professor Deng Qixiang, the "first -generation heir" of the South Chong Normal University (predecessor of Xihua Normal University), has 156 kinds of fish in the Jialing River. The "Second Generation" is a group of researchers represented by Zhou materials of the Ecological Research Institute. They conducted related research on the algae plant community and water quality of the Jialing River Sichuan. The "Third Generation Hepan" is a researcher represented by the School of Life Sciences. They further promote the study of aquatic biological resources and ecological environment such as fish, algae, etc. of the Jialing River Basin.

Zhang Fubin graduated from the Sichuan Agricultural University of Agricultural University with a bachelor's degree in aquaculture. The fourth -generation research team has a total of 7 people, which mainly revolves around the Jialing River to study the upstream fish resources of the Yangtze River. This monitoring provides basic data for the Yangtze River Fishing forbidden Fishing.

132 stand monitoring the province's water areas

It is estimated that the ten -year ban period will continue to be monitored

Looking at Sichuan Shu, there are many rivers, and since ancient times, fish inhabits a blessing. How much is fish resources? What is the living environment of fish? There are 132 monitoring stations in the province, including the Yangtze River dry flow, the Jialing River, the Minjiang River, and the Minjiang River, all of which are included in the monitoring scope and set up a protected area. A total of eight scientific research units and schools have implemented monitoring. There are 23 monitoring stations in Xihua Normal University, which are mainly concentrated in the Jialing River Basin.

Taking the national aquatic plant quality resource protection zone in the southern section of the Jialing River as an example, on November 25, 2010, the Ministry of Agriculture was established with the approval of Announcement No. 1491. The special protection period is throughout the year. It is located in the Jialing River section in the southern county of Sichuan Province, involving 6 towns and towns in the river, with a total length of 60 kilometers. The main protection targets are Chinese inverted stabs, yellow catfish, southern large mouthpieces, and Sichuan white turtles. Other protection objects include rouge fish, Iwara carp, and Chinese tadpoles.

The effect of banning fishing in the Yangtze River requires long -term monitoring and research in the ban on fishing waters. Since last year, Zhang Fubin and his team have participated in it. "It is estimated that the entire decade will continue to be monitored."

Is fishing illegal fishing overnight?

Fishing more like this

"Some people fishing overnight in the southern basin of Jialing River, is it illegal fishing?" Since late June, residents have discovered that a fishing vessels have seen fishing vessels overnight in the Jialing River waters near the southern county near their home, suspecting that it is illegal fishing.

"The fishing boats they see are actually special fishing for the monitoring of aquatic biological resources in key waters in the Yangtze River Basin," Zhang Fubin told the cover journalist that the residents were puzzled that he and their team were in the national water production in the southern section of the Jialing River. Monitor the quality resource protection area.

The survey and monitoring of the province is distributed in the Yangtze River dry flow, main tributaries, and key waters. A total of 132 monitoring stations are responsible for different scientific research units and schools. The specific time is from June-July, September-November, 2022, and each position is monitored for not less than 10 days each time. Xihua Normal University is monitoring through special fishing methods in Guangyuan City, Nanchong City, Guang'an City and other places in the Jialing River Basin.

"Approved by the Special Fishing of the Provincial Agricultural and Rural Affairs Department, wearing the" Yangtze River Ban Fishing "monitoring and evaluation red vest in specific areas, and the inspection of maritime ships in the monitoring area. The comprehensive law enforcement brigade, fishery administration and other departments will urge the implementation units to carry out monitoring and investigation in strict accordance with the standards, and strengthen law enforcement supervision of special fishing. "Zhang Fubin said that because of the habits of fish, there are more fish types fishing at night, and the special specialty can meet the special specialty. Monitoring needs.

The monitoring team hired three fishermen to fish for fishing. They turned out to be fishing for fish. After the Yangtze River banned fishing, they went ashore to become fishermen to assist in law enforcement and guard the Jialing River. Generally, the network will be 2-3 times in the night, and the monitoring personnel will be monitored at the designated place early the next morning.

The fish is classified according to the variety, and the monitor conducts professional appraisal, analysis and records of its body length, weight, food, and health. Except for the invasion of the invasion of the invasion or the fish that is harmful to the waters, fish with good physical fitness will be put back in time to the original waters; In some specimens, the national and provincial key protected fish have not saved the specimen at a time of no more than 3 tails, and the rest of the specimens each time will not exceed 50 tails. Fish decreased sharply

Dr. "" advocates not to "release" blindly

From mid -June to the end of the month, during the 13 -day monitoring period, a total of about 2,000 catties was caught. The monitoring team of Xihua Normal University monitored 45 fish in the waters. Among them, there are 2 types of fish in the national secondary, 3 kinds of fish on the upstream of the Yangtze River, and the advantages of yellow tails, like 鳊, 鳜, and carp. On June 22, the monitoring team also monitored a large mouth of 157 cm in length and 50 catties of weight, the largest single -tailed fish that had been discovered since the monitoring. At present, through the letter of contact, Dakou has been sent to the Institute of Aquatic Research Institute of the Sichuan Academy of Agricultural Sciences for further research.

The Jialing River is the richest river in addition to the Jinsha River and Chishui River. With the changes in the environment, the fish in the Jialing River are also declining sharply. The monitoring in the first half of the year has ended. At present, 45 types of fish have been found in the monitoring of the basin.

Since the Guling River Shangqu, there have been more than a dozen avionics hubs that cut the Jialing River into multiple "lakes". Zhang Fubin told the cover journalist that due to the influence of hydropower stations and fish release. The situation of this river section cannot be reflected in the entire Jialing River Basin. In the monitoring of 1976, there were 156 species of Jialing River. The current monitoring reflects the reality of the sharp decline in the fish of the Jialing River from the side.

Zhang Fubin introduced that the types of "release" were found in the monitoring and evaluation of the Jialing River waters. This is caused by the citizens' ornamental fish release, breeding escape, and invasion of foreign species. "If you want to release it, you must find out the source of fish. Private release will destroy the local aquatic biological ecological balance, and it will also cause local fish gene pollution and ecological disorders."

In addition to monitoring the Jialing River fish resources, Zhang Fubin also investigated the poisonous fish in the Jialing River. There are fewer research on poisonous fish, and science has not been done yet. "It is said that fish gallbladder can be clear. In fact, most fish gallbladder is toxic. Carp, catfish, grass carp and other fish bile on the market are not edible. Poisonous fish bile will be poisoned regardless of raw, cooked food, and brewing wine."
